    Full Text Available On account of its tectonic setting, both seismic and volcanic events are frequent in the Azores archipelago. During the historical period earthquakes and seismic swarms of tectonic and/or volcanic origin have struck S. Miguel Island causing a significant number of casualties and severe damages. The information present in historical records made possible a new macroseismic analysis of these major events using the European Macroseismic Scale-1998 (EMS-98. Among the strongest earthquakes of tectonic origin that affected S. Miguel Island, six events were selected for this study. The isoseismal maps drawn for these events enabled the identification of areas characterized by anomalous values of seismic intensity, either positive or negative, to constrain epicentre locations and to identify some new seismogenic areas. Regarding seismic activity associated with volcanic phenomena six cases were also selected. For each of the studied cases cumulative intensity values were assessed for each locality. The distribution of local intensity values shows that the effects are not homogeneous within a certain distance from the eruptive centre, the area of major impacts relates with the eruptive style and damages equivalent to high intensities may occur in Furnas and Sete Cidades calderas. Combining all the historical macroseismic data, a maximum intensity map was produced for S. Miguel Island.

    Full Text Available The Azores archipelago is located at the triple junction between the Eurasian, Nubian and North American lithospheric plates, whose boundaries are the Mid-Atlantic Ridge and the Azores-Gibraltar Fault Zone. São Miguel is the largest island of the archipelago and is located on the eastern part of the western segment of the Azores-Gibraltar Fault Zone. The Achada das Furnas plateau, located in the central part of the island, between Fogo and Furnas central volcanoes, is dominated by several WNW-ESE and E-W trending alignments of basaltic cinder cones. Two E-W trending scarps were identified by aerial photo interpretation. Transect trenches exposed two active normal faults-the Altiprado Faults – confirming the tectonic nature of the scarps. Several paleoearthquakes were deduced, most of which in historical times, producing 1.38 m and 0.48 m of cumulative displacement. Maximum expected magnitudes (MW determined from slip per event range from 5.7 to 6.7. One of the events probably corresponds to the historical earthquake of October 22nd, 1522, the deadliest in the archipelago. Radiocarbon ages are in agreement with this interpretation.

    Full Text Available Since the settlement of S. Miguel Island (Azores, in the XV century, several earthquakes caused important human losses and severe damages on the island. Sete Cidades Volcano area, located in the westernmost part of the island, was attained by strong seismic crises of tectonic and volcanic origin and major events reached a maximum historical intensity of IX (European Macroseismic Scale 1998 in this zone. Aiming to evaluate the impact of a future major earthquakes, a field survey was carried out in ten parishes of Ponta Delgada County, located on the flanks of Sete Cidades volcano and inside it is caldera. A total of 7019 buildings were identified, being 4351 recognized as dwellings. The total number of inhabitants in the studied area is 11429. In this work, dwellings were classified according to their vulnerability to earthquakes (Classes A to F, using the structure types table of the EMS-98, adapted to the types of constructions made in the Azores. It was concluded that 76% (3306 of the houses belong to Class A, and 17% (740 to Class B, which are the classes of higher vulnerability. If the area is affected by a seismic event with intensity IX it is estimated, that 57% (2480 to 77% (3350 of the dwellings will partially or totally collapse and 15% (652 to 25% (1088 will need to be rehabilitated. In this scenario, considering the average of inhabitants per house for each parish, 82% (9372 to 92% (10515 of the population will be affected. The number of deaths, injured and dislodged people will pose severe problems to the civil protection authorities and will cause social and economic disruption in the entire archipelago.

    Full Text Available Sete Cidades is an active central volcano with a summit caldera located in the westernmost part of S. Miguel Island (Azores. Since the settlement of the Island, in the 15th century, many landslide events occurred in this volcano, causing extensive damages in buildings and infrastructures. The study of historical records and the observation of new occurrences showed that landslides in the region have been triggered by heavy rainfall periods, earthquakes and erosion. In order to assess landslide susceptibility at Sete Cidades Volcano, landslide scars and associated deposits were mapped through aerial photographs and field surveys. The obtained data were inserted in a GIS to produce a landslide distribution map. It was concluded that the high density landslide areas are related with (1 major scarp faults, (2 the margin of fluvial channels, (3 the sea cliffs and (4 volcanic landforms, namely the caldera wall. About 73% of the mapped events took place in areas where pyroclastic deposits are the dominant lithology and more than 77% occurred where slopes are equal or higher than 20°. These two parameters were integrated and used to generate a preliminary susceptibility map. The incorporation of vulnerability data into the GIS allowed concluding that 30% of dwellings and most of the roads on Sete Cidades Volcano are located in areas where landslide susceptibility is high to very high. Such conclusion should be taken into account for emergency and land use planning.

  8. Fluoride content in drinking water supply in São Miguel volcanic island (Azores, Portugal).

    High fluoride contents in the water supply of the city of Ponta Delgada, located in the volcanic island of São Miguel (Azores, Portugal) have been reported. Dental fluorosis in São Miguel has been identified and described in several medical surveys. The water supply in Ponta Delgada consists entirely of groundwater. A study was carried out in order to characterize the natural F-pollution of a group of springs (30) and wells (3), that are associated to active central volcanoes of a trachytic nature. Two springs known for their high content in fluoride were sampled, both located in the central volcano of Furnas. The sampled waters are cold, ranging from slightly acidic to slightly alkaline (pH range 6.53-7.60), exhibiting a low electrical conductivity (springs range 87-502 μS/cm; wells range 237-1761 μS/cm), and are mainly from the Na-HCO(3), Na-HCO(3)-Cl and Na-Cl-HCO(3) water types. Results suggest two main trends of geochemical evolution: silicate weathering, enhanced by CO(2) dilution, and seawater spraying. Fluoride contents range between 0.17 mg/L and 2 mg/L, and no seasonal variations were detected. Results in the sources of the water supply system are lower than those of the Furnas volcano, which reach 5.09 mgF/L, demonstrating the effect of F-rich gaseous emanations in this area. Instead, the higher fluoride contents in the water supply are mainly due to silicate weathering in aquifers made of more evolved volcanic rocks. Copyright © 2012 Elsevier B.V. All rights reserved.

    The evolution of hyperslow oceanic rifts, like the Terceira Rift (TR) in the Azores, is still poorly understood. Here we examine the distribution of strain and magmatism in the portion of the TR making up the Nubia-Eurasia plate boundary. We use São Miguel Island because it stretches most of the TR width, which allows to investigate the TR's architecture and shedding light on TR's age and mode of deformation. From topography and structural analysis, and new measurements of 380 faults and dikes, we show that (1) São Miguel has two main structural directions, N150 and N110, mostly concentrated in the eastern part of the island as an onshore continuation of the faults observed offshore in the NE (N110 faults) and SW (N140) TR walls; (2) a new N50-N80 fault system is identified in São Miguel; (3) fault and dike geometries indicate that eastern São Miguel comprises the TR's northern boundary, and the lack of major faults in central and western São Miguel indicates that rifting is mostly concentrated at master faults bounding the TR. Based on TR's geometry, structural observations and plate kinematics, we estimate that the TR initiated between 1.4 and 2.7 Ma ago and that there is no appreciable seafloor spreading associated with rifting. Based on plate kinematics, on the new structural data, and on São Miguel's structural and volcanic trends, we propose that the eastern two thirds of São Miguel lie along a main TR-related transform fault striking N70-N80, which connects two widely separated N130-N150 TR-trending segments.

    The Azores archipelago has provided significant clues to the ecological, biogeographic and evolutionary knowledge of oceanic islands. Palaeoecological records are comparatively scarce, but they can provide relevant information on these subjects. We report the palynological reconstruction of the vegetation and landscape dynamics of the São Miguel Island before and after human settlement using the sediments of Lake Azul. The landscape was dominated by dense laurisilvas of Juniperus brevifolia and Morella faya from ca. 1280 CE to the official European establishment (1449 CE). After this date, the original forests were replaced by a complex of Erica azorica/Myrsine africana forests/shrublands and grassy meadows, which remained until ca. 1800 CE. Extractive forestry, cereal cultivation (rye, maize, wheat) and animal husbandry progressed until another extensive deforestation (ca. 1774 CE), followed by the large-scale introduction (1845 CE) of the exotic forest species Cryptomeria japonica and Pinus pinaster, which shaped the present-day landscape. Fire was a significant driver in these vegetation changes. The lake levels experienced a progressive rise during the time interval studied, reaching a maximum by ca. 1778-1852 CE, followed by a hydrological decline likely due to a combination of climatic and anthropogenic drivers. Our pollen record suggests that São Miguel were already settled by humans by ca. 1287 CE, approximately one century and a half prior to the official historically documented occupation of the archipelago. The results of this study are compared with the few palynological records available from other Azores islands (Pico and Flores).

    The Geographic Information Systems (GIS) are becoming a major tool in the domain of geological hazard assessment and risk mitigation. When available, hazard and vulnerability data can easily be represented in a GIS and a great diversity of risk maps can be produced following the implementation of specific predicting models. A major difficulty for those that deal with GIS is to obtain high quality, well geo-referenced and validated data. This situation is particularly evident in the scope of risk analysis due to the diversity of data that need to be considered. In order to develop a coherent database for the geological risk analysis of the Azores archipelago it was decided to use the digital maps edited in 2001 by the Instituto Geográfico do Exército de Portugal (scale 1:25000), comprising altimetry, urban areas, roads and streams network. For the particular case of S. Miguel Island the information contained in these layers was revised and rectifications were made whenever needed. Moreover basic additional layers were added to the system, including counties and parishes administrative limits, agriculture and forested areas. For detailed studies all the edifices (e.g. houses, public buildings, monuments) are being individualized and characterized taking in account several parameters that can become crucial to assess their direct vulnerability to geological hazards (e.g. type of construction, number of floors, roof stability). Geological data obtained (1) through the interpretation of historical documents, (2) during recent fieldwork campaigns (e.g. mapping of volcanic centres and associated deposits, faults, dikes, soil degassing anomalies, landslides) and (3) by the existent monitoring networks (e.g. seismic, geodetic, fluid geochemistry) are also being digitised. The acquisition, storage and maintenance of all this information following the same criteria of quality are critical to guarantee the accuracy and consistency of the GIS database through time.

    Since October 2001, four soil CO 2 flux stations were installed in the island of São Miguel (Azores archipelago), at Fogo and Furnas quiescent central volcanoes. These stations perform measurements by the accumulation chamber method and, as the gas flux may be influenced by external variables, the stations are equipped with several meteorological sensors. Multivariate regression analysis applied to the large datasets obtained allowed observing that the meteorological variables may influence the soil CO 2 flux oscillations from 18% to 50.5% at the different monitoring sites. Additionally, it was observed that meteorological variables (mainly soil water content, barometric pressure, wind speed and rainfall) play a different role in the control of the gas flux, depending on the selected monitoring site and may cause significant short-term (spike-like) fluctuations. These divergences may be potentially explained by the porosity and hydraulic conductivity of the soils, topographic effects, drainage area and different exposure of the monitoring sites to the weather conditions. Seasonal effects are responsible for long-term oscillations on the gas flux. Before a reliable application of soil CO 2 flux to seismic and/or volcanic monitoring, it is important to recognize those environmental influences on the gas flux. In addition, understanding the external meteorological influences on the gas flux may be important for the public health risk assessment, since meteorological parameters may cause also significant indoor CO 2 increases. In a house at Furnas Village (in Furnas volcano caldera), the values detected reached percentages as high as 20.8% due to significant decreases in the barometric pressure.

    The extinct São Miguel Scops Owl Otusfrutuosoi n. sp. is described from fossil bones found in Gruta de Água de Pau, a volcanic tube in São Miguel Island (Azores Archipelago, North Atlantic Ocean). It is the first extinct bird described from the Azores and, after the Madeiran Scops Owl (O. mauli Rando, Pieper, Alcover & Olson 2012a), the second extinct species of Strigiformes known in Macaronesia. The forelimb elements of the new taxon are shorter, the hindlimb elements are longer, and the pelvis is shorter and broader than in the Eurasian Scops Owl (O. scops Linnaeus). The new species differs from O. mauli in the smaller size of many of its bones, especially the ulna and tibiotarsus. Its measurements (estimated weight, wing area, and wing loading, and the ratio of humerus + ulna + carpometacarpus length/femur length) indicate weak powers of flight and ground-dwelling habits. The latest occurrence of the new species, as evidenced by a radiocarbon date of 1970 ± 40 BP from bone collagen, indicates a Late Holocene extinction event subsequent to 49 cal BC, and was probably linked to human arrival and subsequent habitat alterations.

    Many studies in volcanic air pollution only have in consideration the acute toxic effects of gas or ash releases however the impact of chronic exposure to ground gas emissions in human health is yet poorly known. In the Azores archipelago (Portugal), São Miguel island has one of the most active and dangerous volcanoes: Furnas Volcano. Highly active fumarolic fields, hot springs and soil diffuse degassing phenomena are the main secondary volcanic phenomena that can be seen at the volcano surroundings. One of the main gases released in these diffuse degassing areas is radon (222Rn), which decay results in solid particles that readily settle within the airways. These decay particles emit alpha radiation that is capable of causing severe DNA damage that cumulatively can eventually cause cancer. Previous studies have established that chronic exposure to chromosome-damaging agents can lead to the formation of nuclear anomalies, such as micronuclei that is used for monitoring DNA damage in human populations. The present study was designed to evaluate whether chronic exposure to volcanic air pollution, associated to 222Rn, might result in DNA damage in human oral epithelial cells. A cross sectional study was performed in a study group of 142 individuals inhabiting an area where volcanic activity is marked by active fumarolic fields and soil degassing (hydrothermal area), and a reference group of 368 individuals inhabiting an area without these secondary manifestations of volcanism (non-hydrothermal area). For each individual, 1000 buccal epithelial cells were analyzed for the frequency of micronucleated cells (MNc) and the frequency of cells with other nuclear anomalies (ONA: pyknosis, karyolysis and karyorrhexis), by using the micronucleus assay. Information on lifestyle factors and an informed consent were obtained from each participant. Assessment of indoor radon was performed with the use of radon detectors. Data were analyzed with logistic regression models, adjusted

    Carbon dioxide (CO2) diffuse degassing structures (DDS) at Furnas volcano (São Miguel Island, Azores) are mostly associated with the main fumarolic fields, evidence that CO2 soil degassing is the surface expression of rising steam from the hydrothermal system. Locations with anomalous CO2 flux are mainly controlled by tectonic structures oriented WNW-ESE and NW-SE and by the geomorphology of the volcano, as evidenced by several DDS located in depressed areas associated with crater margins. Hydrothermal soil CO2 emissions in Furnas volcano are estimated to be ˜968 t d-1. Discrimination between biogenic and hydrothermal CO2 was determined using a statistical approach and the carbon isotope composition of the CO2 efflux. Different sampling densities were used to evaluate uncertainty in the estimation of the total CO2 flux and showed that a low density of points may not be adequate to quantify soil emanations from a relatively small DDS. Thermal energy release associated with diffuse degassing at Furnas caldera is about 118 MW (from an area of ˜4.8 km2) based on the H2O/CO2 ratio in fumarolic gas. The DDS also affect Furnas and Ribeira Quente villages, which are located inside the caldera and in the south flank of the volcano, respectively. At these sites, 58% and 98% of the houses are built over hydrothermal CO2 emanations, and the populations are at risk due to potential high concentrations of CO2 accumulating inside the dwellings.

    We report 63 new radiocarbon analyses of samples from Sao Miguel, the largest island in the Azores archipelago. The samples are mainly carbonized tree roots and other plant material collected from beneath 20 mafic lava flows and spatter deposits and from within and beneath 42 trachytic pyroclastic flow, pyroclastic surge, mudflow, pumice-fall and lacustrine deposits and lava flows. One calcite date is reported. These dates establish ages for 48 previously undated lava flows and pyroclastic deposits, and revise three ages previously reported. These data are critical to deciphering the Holocene and late Pleistocene eruptive history of Sao Miguel and evaluating its potential volcanic hazards. Average dormant intervals during the past 3000 years are about 400 years for Sete Cidades volcano, 145 years for volcanic Zone 2, 1150 years for Agua de Pau volcano and 320 years for Furnas volcano. No known eruptions have occurred in volcanic Zone 4 during the past 3000 years. -from Authors

    Full Text Available Iron overload is associated with acquired and genetic conditions, the most common being hereditary hemochromatosis (HH type-I, caused by HFE mutations. Here, we conducted a hospital-based case-control study of 41 patients from the São Miguel Island (Azores, Portugal, six belonging to a family with HH type-I pseudodominant inheritance, and 35 unrelated individuals fulfilling the biochemical criteria of iron overload compatible with HH type-I. For this purpose, we analyzed the most common HFE mutations- c.845G>A [p.Cys282Tyr], c.187C>G [p.His63Asp], and c.193A>T [p.Ser65Cys]. Results revealed that the family's HH pseudodominant pattern is due to consanguineous marriage of HFE-c.845G>A carriers, and to marriage with a genetically unrelated spouse that is a -c.187G carrier. Regarding unrelated patients, six were homozygous for c.845A, and three were c.845A/c.187G compound heterozygous. We then performed sequencing of HFE exons 2, 4, 5 and their intron-flanking regions. No other mutations were observed, but we identified the -c.340+4C [IVS2+4C] splice variant in 26 (74.3% patients. Functionally, the c.340+4C may generate alternative splicing by HFE exon 2 skipping and consequently, a protein missing the α1-domain essential for HFE/ transferrin receptor-1 interactions. Finally, we investigated HFE mutations configuration with iron overload by determining haplotypes and genotypic profiles. Results evidenced that carriers of HFE-c.187G allele also carry -c.340+4C, suggesting in-cis configuration. This data is corroborated by the association analysis where carriers of the complex allele HFE-c.[187C>G;340+4T>C] have an increased iron overload risk (RR = 2.08, 95% CI = 1.40-2.94, pG;340+4T>C] has a role, as genetic predisposition factor, on iron overload in the São Miguel population. Independent replication studies in other populations are needed to confirm this association.

    Slope instability research and susceptibility mapping is a fundamental component of hazard assessment and is of extreme importance for risk mitigation, land-use management and emergency planning. Landslide susceptibility zonation has been actively pursued during the last two decades and several methodologies are still being improved. Among all the methods presented in the literature, indirect quantitative probabilistic methods have been extensively used. In this work different linear probabilistic methods, both bi-variate and multi-variate (Informative Value, Fuzzy Logic, Weights of Evidence and Logistic Regression), were used for the computation of the spatial probability of landslide occurrence, using the pixel as mapping unit. The methods used are based on linear relationships between landslides and 9 considered conditioning factors (altimetry, slope angle, exposition, curvature, distance to streams, wetness index, contribution area, lithology and land-use). It was assumed that future landslides will be conditioned by the same factors as past landslides in the study area. The presented work was developed for Ribeira Quente Valley (S. Miguel Island, Azores), a study area of 9,5 km2, mainly composed of volcanic deposits (ash and pumice lapilli) produced by explosive eruptions in Furnas Volcano. This materials associated to the steepness of the slopes (38,9% of the area has slope angles higher than 35°, reaching a maximum of 87,5°), make the area very prone to landslide activity. A total of 1.495 shallow landslides were mapped (at 1:5.000 scale) and included in a GIS database. The total affected area is 401.744 m2 (4,5% of the study area). Most slope movements are translational slides frequently evolving into debris-flows. The landslides are elongated, with maximum length generally equivalent to the slope extent, and their width normally does not exceed 25 m. The failure depth rarely exceeds 1,5 m and the volume is usually smaller than 700 m3. For modelling

    A study on diffuse CO2 degassing was undertaken at Furnas lake (São Miguel island, Azores) in order to estimate the total diffuse CO2 output and identify anomalous degassing areas over the lake. Furnas lake is located in Furnas Volcano, the easternmost of the three active central volcanoes of the São Miguel island. The lake has an area of 1.87 km2 and a maximum length and width equal to 2025 and 1600 m, respectively. The maximum depth of the water column is 15 m and the estimated water storage is 14 × 106 m3. Lake water temperature is cold, with temperature values between 13 °C and 15 °C in the winter period and 18.9 °C to 19.3 °C in early autumn, and the variation along the water column suggests a monomictic character. The major-ion relative composition is in decreasing order Na+ > K+ > Ca2+ > Mg2 + for cations and HCO3- > Cl- > SO42- for anions, and conductivity and pH measurements, respectively in the range of 152 to 165 μS cm- 1 and 5.3 to 8.7, suggests that Furnas has neutral-diluted waters and can be classified as a non-active lake. Diffuse CO2 flux measurements were made using the accumulation chamber method with a total of 1537 and 2577 measurements performed in two different sampling campaigns. The total amount of diffuse CO2 emitted to the atmosphere was estimated between 28 and 321 t km- 2 d- 1, respectively, in the second and first sampling campaigns, corresponding to ~ 52 and ~ 600 t d- 1. The main anomalous degassing area identified over the Furnas lake during both surveys is probably associated to a WNW-ESE trending tectonic structure. Other secondary areas are also suggested to be tectonically influenced. Identified anomalous areas showed similarities to the ones observed during previous soil CO2 degassing studies.

    This study aimed to assess the degree of contamination of bulk tank milk (BTM) by Staphylococcus spp. and coliform bacteria and to identify major milking practices that help perpetuate them in dairy cattle herds in São Miguel Island. In July 2014, BTM was sampled and a survey concerning local milking practices was conducted on 100 herds. Semi quantitative multiplex polymerase chain reaction detected coagulase-negative staphylococci, Escherichia coli, Staphylococcus aureus, and other coliform bacteria (Klebsiella oxytoca, Klebsiella pneumoniae, and Serratia marcescens) in 100, 75, 59, and 35 % of BTM, respectively. According to multivariable univariate models, on herds not using hot water for cleaning the milking machine and teat liners, there was at least 3.4 more odds (P < 0.01) to have S. aureus or coliform bacteria contamination in BTM. The likelihood of finding S. aureus in BTM was higher (P < 0.001) on herds without high hygiene during milking, when milking mastitic cows at the end, on abrupt cessation of milking at dry-off, and official milk control implementation. The glove use also favored (odds ratio (OR) 5.8; P < 0.01) the detection of coliform bacteria in BTM. Poor milking practices identified in this study should be avoided in order to decrease S. aureus and coliform bacteria contamination of BTM. Other factors associated with milk quality in São Miguel Island also should be further investigated.

    A field study was developed at Sete Cidades, the westernmost of the three active composite volcanoes that dominate the geology of São Miguel, the largest of the nine islands from the Azores archipelago. Research methodology comprehends the characterization of soil-water composition at several depths, sampled by means of ceramic suction cups. Previously to their installation, cups were all submitted to several stages of washing, first in the laboratory with supra pure water, until aliquot conductivity stabilizes, and after in the field. This study was planned in order to study the water pollution due to agriculture, one of the main economic activities in the Azores, as shown by the gross value added to regional product. The negative effects of groundwater pollution due to agriculture have been reported in the majority of the nine islands, reflected by high contents of nitrogen species, derived from the inadequate use of synthetic and organic fertilizers, as well as from animal wastes leaching, or also by microbiology parameters. The relation between water pollution and agriculture results in some cases in the failure to comply regarding EU and national water quality regulations, through quality deterioration and compromising groundwater as strategic natural resource in the Azores. The studied area corresponds to Sete Cidades volcano caldera, a 5 km-diameter circular shaped depression, contoured by steep walls from 30 m high up to 400 m. In order to characterize unsaturated water composition in the caldera floor, five pasture locations were selected and monitored, as well as one site with the same physical conditions, but without agricultural activity. From the 5 pasture lands we discuss further results obtained in the so-called Pavão I (Pa I), which corresponds to the most extensive data set. On this site, 6 suction cups were installed, at depths 0.35 m, 0.7 m, 1 m, 1.3 m, 1.6 m and 1.9 m. In the site without agricultural activity, in the vicinity of Sete Cidades

    The volcanic islands making up the Azores Archipelago rise above sea from a prominent submarine topographic high (the “Azores Plateau”), marked by the 2000-m bathymetric contour. Specifically, the Azores Islands lie at the so-called “Azores Triple Junction” (ATJ), where the Eurasian, North American, and African (or Nubian) tectonic plates meet. In general terms, the ATJ is defined by the Mid-Atlantic Ridge (MAR) separating the North American plate from the other two, and the Azores–Gibraltar fault zone separating the Eurasian and African plates. In addition, the existence of a mantle plume (“hotspot) beneath Azores Plateau has been inferred in many previous investigations. Not surprisingly, because of its distinctive plate-tectonics setting and attributes, the Azores Archipelago has been the site of intense research, serving as an ideal natural laboratory for scientific studies involving diverse disciplines, including geology, seismotectonics, climatology, ecology, and oceanography. Of course, a special field of interest and research is volcanology, with particular emphasis not only on the eruptive processes and products of the individual island volcanoes, but also of the volcanic and structural evolution of the ATJ and the “Azores Plateau” as a whole.There has been, and remains, considerable scientific debate about the dynamics of the ATJ, including the characterization of the nature and location of the involved plate boundaries, the determination of the sense and amount of plate motions, and the influence of the Azores hotspot on the involved three plates. At present, the basic nature of the ATJ is still not fully understood and the main unresolved issues are: where is the westernmost extent of Azores–Gibraltar fault zone? What is the nature of that extent? Is this fault zone a single, narrowly constricted linear boundary, or does it behave as a much larger, complex tectonic block (i.e., a “miniplate“ or “microplate”)? What is the size

    Iodine deficiency is the most common cause of preventable mental impairment. Although several studies have established an association between ocean proximity and iodine environmental availability, recent studies revealed an inadequate iodine intake in the Azorean islands. In this study, we aim to understand the underlying causes of iodine environmental availability in oceanic islands and its association with iodine intake in schoolchildren, using the Azores as case-study. Iodine concentration in soil and grass pasture was measured by INAA and in drinking water by spectrophotometry. Urinary iodine concentration (UIC) in schoolchildren was assessed by ICP-MS in a randomized cross-sectional survey with 315 participants from S. Miguel (study group) and Sta. Maria islands (reference group). A validated diet questionnaire assessing sources of iodine was recorded. The iodine concentration in soils of the reference group was significantly higher than in the study group (58.1 ppm vs. 14.5 ppm, respectively; p = 0.001). The prevalence of schoolchildren with inadequate UIC was significantly higher in the study group than in the reference one (63.0% vs. 37.8%, respectively; p < 0.001). Chronic exposure to low iodine environmental availability was significantly associated with the exacerbation in iodine deficiency, with a risk 4.94 times higher in the study group. The differences observed in the studied islands are related with each island geomorphology (soil properties and orography) and climate, which can promote or inhibit iodine environmental availability, contributing distinctively to iodine bioavailability and human intake. These findings draw attention to an urgent need for a full investigation of Azores iodine status to apply evidence-based recommendations for iodine supplementation. - Highlights: • Iodine intake in schoolchildren differs between islands of the Azorean archipelago. • Island geomorphology and climate modulate iodine environmental availability. • In

    The management and sustainability of the traditional vineyards of the Azores settled on lava field terrains is strongly affected by practical limitations of mechanization and high demand on man labor imposed by the typical micro parcel structure of the vineyards. In a recent macrozoning approach study Madruga et al (2015) showed that besides the traditional vineyards there are significant areas in some of the Azores islands whose soils, climate and physiographic characteristics indicate a potential for the development of new vineyard areas offering conditions for better management and sustainability. The objective of this study was to conduct a detailed viticultural zoning at the level of the small mapscale (smaller than 1:25,000), for the island of Graciosa where, besides the traditional lava field terroir, there are also some localized experiences of grapevine production over normal soils, offering thus some comparative information on this type of production conditions. The zoning approach for the present study was based in a geographic information system (GIS) analysis incorporating factors related to climate and topography which was then combined with the soil mapping units fulfilling the suitable criteria concerning the soil properties taken as the most relevant for viticulture, being the result a map of homogeneous environmental units. The climatic zoning examined the direct quantitative variables (precipitation, temperature, evaporation) in relation to climate index, bioclimatic and viticultural specific values. Topography (elevation, slope, aspect, orientation) was analyzed based on the tridimensional models of the islands in GIS to include the best slopes for the mechanization of the vineyard cultural operations (0-15%). Soils were analyzed based on data and soil map units as defined in the soil surveys of the Azores archipelago. The soil properties taken for the analysis and definition of the potential vineyard areas were drainage, water holding capacity

  7. The Persistence of Stereotyped Dialect Features among Portuguese-American Immigrants from São Miguel, Azores

    Full Text Available Among dialects of Portuguese, the variety indigenous to the island of São Miguel exhibits an inventory of vocalic features not found elsewhere in the Lusophone world. The most emblematic characteristics of this dialect are the front round vowels [y] and [ø], which correspond to [u] and [ou/oi] (respectively of the European standard language. There are also systematic differences in the pronunciation of the tonic vowels, reflexes of a historical chain shift: sete ‘seven’ is often rendered in S. Miguel as [sæt] (Std. [sεt], avó ‘grandmother’ as [ɐ'vo] (Std. [ɐ'vɔ], and avô ‘grandfather’ as [ɐ'vu] (Std. [ɐ'vo]. While these characteristic are attested in the contemporary speech of the island, one might ask whether they persist in the speech of Azorean emigrants in the United States. This paper presents a phonetic analysis of four emigrants from the village of Nordeste, members of the same family, each of whom presents different phonetic behaviors. While three speakers preserve most of the speech reflexes characteristic of the island, one presents a vocalic inventory more like that of the standard language. This variability reflects a tension between behaviors emblematic of Micaelense identity (e.g., [y] < [u] and a need to accommodate to sociolinguistic pressures exerted by the standard language, which predominates in the larger community of Portuguese immigrants.

    Corvo and Flores islands belong to the western group of the Azores archipelago, to the west of the Mid-Atlantic Ridge. Several studies have proposed a common magmatic evolution for both islands. However, most of these studies focus on other Azorean islands. In order to investigate the processes that control the evolution of Corvo and Flores we have studied representative samples of the whole volcanostratigraphical sequence in both islands, including lava flows and dikes. Similarly to other oceanic islands, Corvo and Flores are made up of an alternation of porphyritic rocks and microlitic rocks. The former are picrobasalts and basalts with 5 to 60 volume fraction of large (2-15 mm), primitive antecrysts of olivine, clinopyroxene and plagioclase. The latter are Mg-poor hawaites to trachytes. The Mg-rich composition of the porphyritic rocks is due to the accumulation of primitive antecrysts within a more evolved groundmass. In contrast, the composition of the microlitic rocks provides information on the differentiation processes that controlled the evolution of both islands. The microlitic rocks present holocrystalline to hypocrystalline textures with a mineral assemblage mainly composed of microcrysts of plagioclase, olivine, clinopyroxene opaque minerals and accessory amphibole and apatite. Their major element whole rock composition can be best modeled by a polybaric fractional crystallization process (MELTS software) starting at 500 MPa with cooling steps of 5 degrees Celsius and a water content of 1 %, starting from the most primitive analyzed microlitic rock (MgO: 9.04%; Cr: 630 ppm; Ni: 200 ppm). Hence, we confirm that both islands derived from a common primary magma. The crystallization of the antecrysts included in the porphyritic rocks was probably related to the initial stages of the differentiation process. On the other hand, the microlitic rocks and the groundmass of the porphyritic rocks are related to the residual melts of the polybaric fractional

    The growth and decay of ocean-island volcanoes are intrinsically linked to vertical movements. While the causes for subsidence are better understood, uplift mechanisms remain enigmatic. Santa Maria Island in the Azores Archipelago is an ocean-island volcano resting on top of young lithosphere, barely 480 km away from the Mid-Atlantic Ridge. Like most other Azorean islands, Santa Maria should be experiencing subsidence. Yet, several features indicate an uplift trend instead. In this paper, we reconstruct the evolutionary history of Santa Maria with respect to the timing and magnitude of its vertical movements, using detailed field work and 40Ar/39Ar geochronology. Our investigations revealed a complex evolutionary history spanning ∼6 m.y., with subsidence up to ca. 3.5 Ma followed by uplift extending to the present day. The fact that an island located in young lithosphere experienced a pronounced uplift trend is remarkable and raises important questions concerning possible uplift mechanisms. Localized uplift in response to the tectonic regime affecting the southeastern tip of the Azores Plateau is unlikely, since the area is under transtension. Our analysis shows that the only viable mechanism able to explain the uplift is crustal thickening by basal intrusions, suggesting that intrusive processes play a significant role even on islands standing on young lithosphere, such as in the Azores.

    Full Text Available This paper aims to assess the effectiveness of ASTER imagery to support the mapping of Pittosporum undulatum, an invasive woody species, in Pico da Vara Natural Reserve (S. Miguel Island, Archipelago of the Azores, Portugal. This assessment was done by applying K-Nearest Neighbor (KNN, Support Vector Machine (SVM and Maximum Likelihood (MLC pixel-based supervised classifications to 4 different geographic and remote sensing datasets constituted by the Visible, Near-Infrared (VNIR and Short Wave Infrared (SWIR of the ASTER sensor and by digital cartography associated to orography (altitude and "distance to water streams" of which the spatial distribution of Pittosporum undulatum directly depends. Overall, most performed classifications showed a strong agreement and high accuracy. At targeted species level, the two higher classification accuracies were obtained when applying MLC and KNN to the VNIR bands coupled with auxiliary geographic information use. Results improved significantly by including ecology and occurrence information of species (altitude and distance to water streams in the classification scheme. These results show that the use of ASTER sensor VNIR spectral bands, when coupled to relevant ancillary GIS data, can constitute an effective and low cost approach for the evaluation and continuous assessment of Pittosporum undulatum woodland propagation and distribution within Protected Areas of the Azores Islands.

    A 16 station array was operated over the 200 km**2 central portion of Sao Miguel utilizing 8 permanent Instituto Nacional de Meterologia e Geofisica stations and 8 USGS portable stations. Forty four local events with well constrained solutions and 15 regional events were located. In addition, hundreds of unlocatable seismic events were recorded. The most interesting seismic activity occurred in a swarm on September 6 and 7, 1983 when over 200 events were recorded in a 16 hour period. The seismic activity around Agua de Pau was centered on the east and northeast slopes of the volcano. The data suggest a boiling hydrothermal system beneath the Agua de Pau volcano, consistent with a variety of other data.

    The Azores archipelago (Portugal), located in the Atlantic Ocean, 1,500 km from the European mainland, is formed by nine islands of volcanic origin. The relative position of these islands allows the definition of three geographical groups: Eastern, Central and Western. Previous studies of the Azores using Short Tandem Repeats (STRs) have highlighted differences in the frequencies of several loci, when compared to Mainland Portugal or Madleira Island. Furthermore, linkage disequilibrium (LD), described for Azorean samples has been tentatively explained as reflecting the presence of genetic sub-structuring in the archipelago. To provide information concerning the genetic profile of the Azores Islands and to evaluate the presence of substructuring we have determined the allelic frequencies of 15 autosomal STR loci, using the AmpFlSTR Identifiler Kit, in representative samples from the Azorean Islands. Either considering the Azores as a whole, or analysing by island all the loci were in conformity with Hardy-Weinberg equilibrium. Average gene diversity ranged from 0.7669 in Corvo to 0.7972 in Terceira Island. Allelic independence between loci, tested for the global sample, detected significant LD (after correction for multiple tests) for pairs D21S11/D7S820 and D3S1358/D5S818. The exact test of population differentiation, combining the information of the 15 markers analysed, revealed significant differences between the three groups of islands, and between islands. Inter-island analysis reinforces the previous data that suggested the existence of sub-structuring in the Azores archipelago. Moreover, the data generated by this study can be used in a future forensic genetic database of the Azores after the appropriate enlacement of sample size by island, preventing, in that way, misinterpretations caused by population substructuring and small sample sizes.

    Eutrophication of lakes in the Azores archipelago (Portugal) has been described since the 80s, and due to water quality deterioration several remediation methodologies were applied. Long-term monitoring data on water quality from Sete Cidades and Furnas lakes (São Miguel island) were analyzed in order to address that the success of the ongoing policy reverses their eutrophic status. Sete Cidades lake (4.46 km2), made by two branches (so-called Green and Blue lakes), has a water volume equal to 58×10(6) m3 and a depth in the range between 24 and 28.5m. Furnas lake (1.87 km2) has a volume equal to 14×10(6) m3 and a maximum depth of 15m. In Sete Cidades lake mean water temperature and pH range respectively between 13.4°C to 17.7°C and 7.04 to 8.06. Instead, mean temperature in Lake Furnas ranges between 16.6°C and 17.2°C, with a pH between 7.36 and 7.84. Mean water conductivity shows that both lakes correspond to very diluted waters, with values between 98.1 and 136.5 μS/cm. Water chemistry is influenced by the monomictic character of the lakes, as anoxic environment in the hypolimnion due to O2 consumption during the summer, when stratification prevents mixing along the water column, explains sharp increase in TP, TN, N-ammoniacal, Mn and Fe. Major-ion content is rather constant along time, with some seasonal fluctuations, despite a decrease in SO4 observed in Sete Cidades lake which is suggested to be a result of runoff diversion, a result also shown by the decrease of the molal ratio TN/TP in both studied lakes. Nevertheless, the application of the trophic state index (TSITP) does not suggest an improvement in what concerns trophic status, which is explained by the internal P-loading, a source that have to be managed by environmental authorities in the near future in order to revert eutrophication.

    The 4.6 ka Fogo A trachytic Plinian eruption on São Miguel Island, Azores, Portugal, is composed by four main phases: 1) Initial phreatomagmatic activity which emplaced thin surge deposits with accretionary lapilli; 2) fully buoyant steady Plinian activity which generated a prominent trachytic basal fall-out deposit; 3) partial collapsing activity, which led to the emplacement of two trachytic-trachydacitic intra-plinian ignimbrites (pink and black ignimbrites) and associated surge deposits, inter-stratified within two fall-out deposits; 4) vent widening and fully collapsing activity which caused the emplacement of the climactic brown trachydacitic ignimbrite. The deposits of these four main phases have been organised into three members FGA1, FGA2 and FGA3, sub-divided into 15 stratigraphic or emplacement units. The fluctuations from a steady to unsteady Plinian eruption column parallel the change in composition of the magma from trachytic to trachydacitic. Although minimal, the change in composition resulted in a marked change in colour of the juvenile clasts from white at the base (first phase) to pink and light-dark grey banded and black (second and third phases) and to dark brown (fourth phase). Density analysis of juvenile clasts revealed that the change in composition did not significantly affect the density of the juvenile pumice pyroclasts, the vesicularity of which increases from 70% to 85% up through the sequence. The pink and the black intra-plinian ignimbrites were emplaced only, within the narrow paleo-valleys of the southern flank with maximum thicknesses of 9 m and 5 m respectively, transitioning onto adjacent topographic highs where thin veneer surge layers were deposited. The fall-out deposits inter-bedded between the ignimbrites lack basal reverse grading, indicating that the eruption column continued to be sustained during the partial collapses generating the intra-plinian ignimbrites. The climactic dark brown ignimbrite was emplaced radially

    The paper briefly describe the basic studies, design and construction at the Island of Pico, Azores, of a shoreline wave-energy pilot plant of oscillating water column (OWC) type. Research in wave energy started in Portugal in 1978 at Instituto Superior Tecnico (IST), later (1983) joined by Instituto Nacional de Engenharia e Tecnologia Industrial (INETI, a national laboratory owned by Ministry of Industry and Energy). The first plans to build a wave power plant at the Azores can be traced back to 1986, when a team from IST, INETI and Heriot-Watt University visited the archipelago at the invitation of EDA, the Azores utility. This was followed by further visits. A suitable site for erecting a shoreline OWC plant was identified in 1987 at Porto Cachorro, on the northern coast of the Island of Pico. In 1991 the European Commission (JOULE programme) started a series of Preliminary Actions in Wave Energy R&D. One of these actions was an European Pilot Plant Study (1992-93), which was carried out by an international team. The study identified several sites suitable for a shoreline pilot plant in European coastal waters. One of them was Porto Cachorro, in the Azores. In 1993 and 1995, contracts were signed with the European Commission (JOULE programme) for the basic studies, design and construction of a pilot plant at the island of Pico. This was to be carried out by an European team from Portugal, the United Kingdom and Ireland.

    The literature concerning Strategic Environmental Assessment (SEA) often refers to the importance of context-specific approaches. However, there is a lack of systematised and consistent studies that enhance tailor-made SEA practices and procedures. Small islands are bounded units of study which may help explore SEA theory and practice in special territories. Small islands present particular features and unique values, such as, small size and population, geographic isolation, limited resources and vulnerable ecosystems. Hence, the main goal of this research was to profile SEA practices and procedures in European small islands and provide a background for future research aiming to improve context-specific SEA applications. To achieve this goal, an exploratory case study was developed using Azores (Portugal) and Orkney (Scotland) archipelagos. An analysis of the corresponding mainland was also carried out to contextualise both case studies. The data collection was achieved through a qualitative content analysis of 43 Environmental Reports. The research found that there is not an SEA context-specific approach used within these European small islands, including guidelines, assessment topics, assessment techniques, follow-up and stakeholders engagement. The debate concerning specific approaches to small islands must be re-focused on the enhancement of SEA capacity-building amongst different stakeholders (including decision-makers), on the development and implementation of collaborative approaches, and on the exchange of knowledge and experiences between small islands networks. - Highlights: • Reviewed the differences between the Portuguese and Scottish SEA system • Showed a low integration of SEA specific features in reports of European small islands • Provides background for future SEA research for small islands approaches.

    The Ribeira Grande geothermal field is a water-dominated geothermal system, located within Água de Pau/Fogo Volcano in the central part of the São Miguel Island. This geothermal system is exploited for energy production by wells sustaining two power plants. The wells produce from a formation of pillow lavas divided into different aquifers, with a fairly isothermal zone from 800 to 1300 m in depth, where reservoir temperature reaches 230 to 245 °C. Below the depth of 1300 m there is a slight temperature reversal. The fluid produced has excess enthalpy and, separated at atmospheric pressure, is characterized by mineralization of sodium-chloride type up to 6-7 g/l, the concentration of dissolved silica varies between 450 and 650 mg/l and the pH ranges between 8 and 8.6. The gas phase is dominantly CO 2, at a concentration of 98% of NCG. The composition of the deep geothermal fluid was obtained by computer simulation, using the WATCH program, and was compared with the composition of the bottom-hole samples. The approximations, in this simulation, were considered the single- and multi-step steam separation. The reference temperatures were based on: (i) the measured temperature in wells; (ii) the Na/K geothermometric temperature and (iii) the enthalpy-saturation temperature. According to both the measured and geothermometric temperatures, the deep fluid of the wells has two phases with a steam fraction up to 0.34, at higher well discharges. The measured enthalpy is always greater than the calculated enthalpy. The calcite equilibrium indicates scaling, since the fluid is flashing, around 2.28 mg/l CaCO 3 at the maximum discharge. The geothermal wells exploit three different aquifers, the lower of which is liquid and slightly colder than the upper ones. The intermediate is a two-phase aquifer with a steam fraction up to 0.081. The upper aquifer is probably of steam phase. The main differences between the aquifers are the temperature and boiling; both enthalpy and

    The Azores islands in the central North-Atlantic originate from a regional melting anomaly, probably created by melting hot, unusually hydrous and geochemically enriched mantle. Here, we present Hf, Pb and Os isotopic data in geochemically well-characterised primitive lavas from the islands Flores and Corvo that are located west of the Mid-Atlantic Ridge (MAR), as well as submarine samples from a subsided island west of Flores and from Deep Sea Drilling Project (DSDP) holes drilled in the western part of the Azores platform and beyond. These are compared to existing data from the Azores islands east of the MAR. The geodynamic origin of the two islands west of the ridge axis and furthest from the inferred plume centre in the central part of the plateau is enigmatic. The new data constrain the source compositions of the Flores and Corvo lavas and show that the western and eastern Azores mantle is isotopically similar, with the exception of an enriched component found exclusively on eastern São Miguel. Trace element ratios involving high field strength elements (HFSE) are distinctly different in the western islands (e.g. twofold higher Nb/Zr) compared to any of the islands east of the MAR. A similar signature is observed in MAR basalts to the south of the Azores platform and inferred to originate from (auto-) metasomatic enrichment of the sub-ridge mantle (Gale et al., 2011, 2013). In a similar fashion, low degree melts from an enriched source component may metasomatise the ambient plume mantle underneath the western Azores islands. Melting such a modified plume mantle can explain the chemical differences between lavas from the western and eastern Azores islands without the need for additional plume components. Recent re-enrichment and intra melting column modification of the upwelling mantle can cause local to regional scale geochemical differences in mantle-derived melts.

    In a baseline study, muscle and liver from important commercial fish belonging to different trophic levels were analysed for organochlorines. Samples of sole, sardine and hake were collected from seven locations off the Continental coast and greater forkbeard and horse mackerel off two Azores islands. Residues of pp'DDT, pp'DDE and PCBs were present in all muscle and liver samples. pp'DDD occurred in all liver samples and in most muscle samples, except in sole where it occurred in 29% of the samples. Dieldrin was detected less frequently and did not occur in samples from the Azores. The residue levels were generally similar to those detected in related species from the North Sea, except for samples of sole collected between the Tagus and Sado estuaries where much higher residues were obtained. In view of the low consumption of insecticides in the Azores, it is proposed that long-range transport of organochlorines by winds and/or marine currents is responsible for their presence in this area. The organochlorine residues found in these fish showed no relationship with their position in the food chain but the values did increase with the quantity of lipids present. An unknown compound analysed by GC-MS interfered with DDE quantification in one sample of greater forkbeard.

    The late Pliocene to Quaternary (5 Ma) volcanism in the central and eastern Azores Archipelago is related to the Eurasia/Africa divergence, but a clear deformation pattern has not yet been established at this location. This work focuses on the contribution of Synthetic Aperture Radar (SAR) scenes and Digital Elevation Models (DEM), complemented with geophysical, geodetic and morpho-structural data, to establish the geometric relationships between volcanic edifices and tectonic structures in the central and eastern Azores Archipelago. Bathymetric data were also used to extend field observations to the significant submarine area of the Azores plateau. Strikes of extension fractures, directly observed or inferred from elongated volcanic vents or linear volcanic clusters in Terceira Island, indicate that volcanism is mainly controlled by regional extension as given by NUVEL-1A plate motion model. Additionally, other directions were also detected for extension fractures around the Santa Barbara volcano (defining a radial pattern) and in the central part of the island (exhibiting an S-shape pattern). Although most of the volcanic vents are controlled by extension fractures, some seem to be controlled by faulting, such as the case of the ones rooted in releasing bends along strike-slip or oblique-slip faults in the central part of the island. Concerning the Azores plateau, most of the structures have directions that do not directly fit with present-day direction of relative motion (˜ N70°) between Eurasia and Africa. Directions ranging from N110° to N125°, found mainly along the Terceira rift, are interpreted as ancient transform directions, reactivating as transtensional fault zones due to the present-day plate motion. N-S directions are also visible in the plateau, being interpreted as former middle-oceanic rift faults reactivated as left-lateral fault zones. These results contrast with the volcanic expression in other hotspot dominated oceanic islands such as the

    The Azores archipelago is composed of nine volcanic islands located at the triple junction between the North American, Eurasian and Nubian plates. Nowadays the volcanic activity in the archipelago is characterized by the presence of secondary manifestations of volcanism, such as hydrothermal fumaroles, thermal and cold CO2-rich springs as well as soil diffuse degassing areas, and low magnitude seismicity. Soil CO2 degassing (concentration and flux) surveys have been performed at Pico, Faial and São Jorge islands to identify possible diffuse degassing structures. Since the settlement of the Azores in the 15th Century these three islands were affected by seven onshore volcanic eruptions and at least six destructive earthquakes. These islands are crossed by numerous active tectonic structures with dominant WNW-ESE direction, and less abundant conjugate NNW-SSE trending faults. A total of 2855 soil CO2 concentration measurements have been carried out with values varying from 0 to 20.7 vol.%. Soil CO2 flux measurements, using the accumulation chamber method, have also been performed at Pico and Faial islands in the summer of 2011 and values varied from absence of CO2 to 339 g m-2 d-1. The highest CO2 emissions were recorded at Faial Island and were associated with the Pedro Miguel graben faults, which seem to control the CO2 diffuse degassing and were interpreted as the pathways for the CO2 ascending from deep reservoirs to the surface. At São Jorge Island, four main degassing zones have been identified at the intersection of faults or associated to WNW-ESE tectonic structures. Four diffuse degassing structures were identified at Pico Island essentially where different faults intersect. Pico geomorphology is dominated by a 2351 m high central volcano that presents several steam emissions at its summit. These emissions are located along a NW-SE fault and the highest measured soil CO2 concentration reached 7.6 vol.% with a maximum temperature of 77 ºC. The diffuse

    Full Text Available Necropsy and extensive parasitological examination of dead northern elephant seal (NES pups was done on San Miguel Island, California, in February, 2015. The main interest in the current study was to determine if hookworms were present in NESs on San Miguel Island where two hookworm species of the genus Uncinaria are known to be present - Uncinaria lyonsi in California sea lions and Uncinaria lucasi in northern fur seals. Hookworms were not detected in any of the NESs examined: stomachs or intestines of 16 pups, blubber of 13 pups and blubber of one bull. The results obtained in the present study of NESs on San Miguel Island plus similar finding on Año Nuevo State Reserve and The Marine Mammal Center provide strong indication that NES are not appropriate hosts for Uncinaria spp. Hookworm free-living third stage larvae, developed from eggs of California sea lions and northern fur seals, were recovered from sand. It seems that at this time, further search for hookworms in NESs would be nonproductive.

    The Azores plateau is located near the Mid-Atlantic Ridge and consists of nine islands. Various methods including seismic reflection, gravity, and passive seismology, have been used to investigate the crustal thickness beneath the islands. They have yielded depth estimates that range between roughly 10 km and 30 km, but until now, a model of the fine-scale crustal structure has been lacking. Geochemical studies carried out across the islands suggest the existence of volcanic interfaces within the shallow crust. Moreover, magma might have accumulated beneath the existing crust (magmatic underplating), causing a shift of the crust-mantle boundary to lower depths. In this study, we use data from ten seismic stations located on the Azores Islands to investigate the crustal structure with P-wave receiver functions (PRFs). A challenge of using ocean island data is oceanic noise that interferes with the useful conversion signals. Here, we employ a frequency-domain deconvolution with objective regularisation based on the pre-event noise spectrum to reduce the effect of the oceanic noise. Our fine-scale PRFs yield conversions at about 0.3 s, 1 s, and 2-3.5 s, which we attribute to a shallow volcanic interface, a mid-crustal interface, and the crust-mantle boundary, respectively. Following the interpretation of similar PRF studies beneath other volcanic ocean islands, the 1 s signal (mid-crustal interface) may correspond to a conversion at the top of the underplated magmatic material. Underplating is most pronounced in the southeastern portion of the Azores plateau. Considering lower seismic P- and S-wave velocities within the volcanic interfaces (vp=4.9 km/s, vs=2.6 km/s) and higher velocities within the underplated material (vp=7.3 km/s, vs=4.2 km/s) compared to the normal crust (vp=6.3 km/s, vs=3.6 km/s), the total crustal thickness amounts to approximately 12-15 km.

    Childhood overweight and obesity are increasing all over the world and have been associated with low levels of physical activity (PA). To determine the prevalence of overweight, obesity and PA levels in Azorean children according to age and sex; and to determine the association between levels of PA and prevalence of overweight and obesity. Weight, height and PA levels were measured in 3699 children aged 6-10 years, from the Azores Islands, Portugal. Overweight and obesity were classified according to the cut-offs of Cole et al. (BMJ 320:1240-1243, 2000) . In girls, prevalences of overweight and obesity were 22.8% and 13.2%, and in boys 17.6% and 12.3%, respectively. No age trends were found in the prevalence of overweight or obesity; however, girls had a higher risk of being overweight (OR = 1.4, 95% CI = 1.2-1.7) than boys. Levels of PA were higher in boys compared to girls (F(1) = 52.8, p active versus less active) was observed for obesity (OR = 0.7; 95% CI = 0.5-0.9). The results demonstrate the existence of high prevalence of overweight and obesity in children from the Azores Islands, which is associated with low levels of PA.

    ABSTRACT Objectives: to dimension abuse against vulnerable adults within the family and community environment in the Azores Islands, identify risk factors for abuse and describe the profile of an abused elder. Method: descriptive cross-sectional study. Random sampling. The instruments used were: clinical histories of the users, Mini-Mental State Examination, Index of Independence in Basic Activities of Daily Living, Family APGAR Scale, Elder Abuse Suspicion Index and Social Work Assessment Form. Descriptive statistical analysis was used for qualitative and quantitative variables and multiple logistic regression was used to identify factors associated with elder mistreatment. Results: abuse suspicion was identified in 24.5% of elderly participants. Psychological abuse was the most common type of abuse and sons were the main abusers. Conclusion: being a woman and belonging to a dysfunctional family is associated with an increased risk of becoming a victim of abuse; the high level of domestic violence against the elderly in the Azores Islands is in line with the rest of Portugal.

    Population dynamics studies are very important for any area-wide control program as they provide detailed knowledge about the relationship of Medfly [Ceratitis capitata (Wiedemann)] life cycle with host availability and abundance. The main goal of this study is to analyse seasonality of C. capitata in Terceira and Sao Jorge Islands (Azores archipelago) using field and laboratory data collected during (2010–2014) CABMEDMAC (MAC/3/A163) project. The results from Sao Jorge Island indicate significantly lower male/female ratio than on Terceira Island. This is an important finding specially regarding when stablishing the scenario parameters for a sterile insect technique application in each island. The population dynamics of C. capitata are generally linked with host fruit availability and abundance. However, on Terceira Island fruit infestation levels are not synchronized with the trap counts. For example, there was Medfly infestations in some fruits [e.g., Solanum mauritianum (Scop.)] while in the nearby traps there were no captures at the same time. From this perspective, it is important to denote the importance of wild invasive plants, on the population dynamics of C. capitata, as well important to consider the possibility of having different densities of traps according to the characteristics of each area in order to improve the network of traps surveillance’s sensitivity on Terceira Island.

    Analyses of species-diversity patterns of remote islands have been crucial to the development of biogeographic theory, yet little is known about corresponding patterns in functional traits on islands and how, for example, they may be affected by the introduction of exotic species. We collated trait data for spiders and beetles and used a functional diversity index (FRic) to test for nonrandomness in the contribution of endemic, other native (also combined as indigenous), and exotic species to functional-trait space across the nine islands of the Azores. In general, for both taxa and for each distributional category, functional diversity increases with species richness, which, in turn scales with island area. Null simulations support the hypothesis that each distributional group contributes to functional diversity in proportion to their species richness. Exotic spiders have added novel trait space to a greater degree than have exotic beetles, likely indicating greater impact of the reduction of immigration filters and/or differential historical losses of indigenous species. Analyses of species occurring in native-forest remnants provide limited indications of the operation of habitat filtering of exotics for three islands, but only for beetles. Although the general linear (not saturating) pattern of trait-space increase with richness of exotics suggests an ongoing process of functional enrichment and accommodation, further work is urgently needed to determine how estimates of extinction debt of indigenous species should be adjusted in the light of these findings.

    Background A central aim of island biogeography is to understand the colonization history of insular species using current distributions, fossil records and genetic diversity. Here, we analyze five plastid DNA regions of the endangered Juniperus brevifolia, which is endemic to the Azores archipelago. Methodology/Principal Findings The phylogeny of the section Juniperus and the phylogeographic analyses of J. brevifolia based on the coalescence theory of allele (plastid) diversity suggest that: (1) a single introduction event likely occurred from Europe; (2) genetic diversification and inter-island dispersal postdated the emergence of the oldest island (Santa Maria, 8.12 Ma); (3) the genetic differentiation found in populations on the islands with higher age and smaller distance to the continent is significantly higher than that on the younger, more remote ones; (4) the high number of haplotypes observed (16), and the widespread distribution of the most frequent and ancestral ones across the archipelago, are indicating early diversification, demographic expansion, and recurrent dispersal. In contrast, restriction of six of the seven derived haplotypes to single islands is construed as reflecting significant isolation time prior to colonization. Conclusions/Significance Our phylogeographic reconstruction points to the sequence of island emergence as the key factor to explain the distribution of plastid DNA variation. The reproductive traits of this juniper species (anemophily, ornithochory, multi-seeded cones), together with its broad ecological range, appear to be largely responsible for recurrent inter-island colonization of ancestral haplotypes. In contrast, certain delay in colonization of new haplotypes may reflect intraspecific habitat competition on islands where this juniper was already present. PMID:22110727

The molecular characterization of a group of 33 possible cases of FH of Azorean background was undertaken in this study. A DNA array was initially used to search mutations in the LDLR, APOB and PCSK9 loci in 10 unrelated possible cases of FH. No mutations were detected in the array; after sequencing the full LDLR gene, 18 variants were identified, corresponding to two missense (c.806G > A; c.1171G > A and sixteen synonymous alterations. Six of the synonymous variants which are consistently described in the literature as associated with altered cholesterol levels were used to build haplotypes. The most frequent haplotype corresponded to TTCGCC (45%, a “risk” haplotype, formed exclusively by alleles that were reported to increase cholesterol levels. Some of the variants detected in the full sequencing of the LDLR gene fell within the ligand-binding domain of this gene, defined by exons 2 to 6. To add information as to the role of such variants, these exons were sequenced in the remaining 23 possible FH cases. Two missense alterations (c.185C > T; c.806G > A were found in this subset of possible FH cases. The missense alteration c.185C > T, identified in one individual, is novel for the Portuguese population. In silico analysis was not conclusive for this alteration, whose role will have to be further investigated.

    Engineering IT-Enabled Electricity Services: The Tale of Two Low-Cost Green Azores Islands covers sustainable energy services to customers - a balanced choice and coordination of energy generated by traditional and alternative sources. The “Green Islands” project represents a decade of work by over a dozen researchers who have developed a model designed to utilize the potential of distributed clean resources. The key is the proper use of Information Technology (IT).  Sited on two islands in the Azores, the project developed the model of careful forecasting of demand and supply, down to the minute, coordinating the output of conventional power plants, wind energy, fly wheels, hydroelectricity, demand reduction, and even plug-in electric vehicles to take full advantage of the clean resources available. This contributed volume presents methods for predicting variable resources, such as wind power generation, and analyzes the achievable accuracy of these predictions. Throughout this book, contributors sho...

    Oceanic islands are by nature unstable volcanic buildings generally marked by rapid growth that alternates with destruction due to a variety of mass-wasting processes, including giant sector collapses, vertical caldera subsidence, fault generation/propagation, shallow landslides and coastal erosion. Due to its diverse volcanic and tectonic frameworks, the Azores archipelago represents an excellent case study for geophysical and geological proposes. Main results of a paleomagnetic study, conducted on oriented samples from approximately 60 accessible lava piles of three islands of Azores archipelago central group (Faial, Pico and Terceira islands) and covering as much as possible spatially and temporally these islands are: i) The paleomagnetic polarity is in close agreement with the radiometric results known for these islands; ii) Onshore volcanic activity began during the Matuyama geochron for Faial and during Brunhes for Terceira and Pico; iii) The mean ChRMs from Terceira and Pico islands result in a paleomagnetic pole similar to the ones retrieved from the studies of Johnson et al (1998) and Silva et al (2012), from S. Miguel and S. Jorge islands (other islands of Azores archipelago), respectively; iv) ChRMs from Faial show an elliptical distribution perpendicular to the WNW-ESE grabben that is the major structure of the island, suggesting tilting towards SSW of the southern wall and towards NNE of the northern one. The presence of listric faults plunging towards the middle of the grabben and aligned along the N110º azimuth could explain the elliptical distribution of paleomagnetic directions. This study is a contribution for the research project REGENA (PTDC/GEO-FIQ/3648/2012).

    Oceanic volcanic islands typically evolve through large-scale short-term events, either constructing or destructing the volcanic edifice. This tug of war between construction and catastrophic destruction should be recorded within a volcanic island, but old collapse events are sometimes hard to recognize because a number of processes modify the associated structures; therefore, recognition of the testimony of such events onshore, without recourse to offshore high-resolution bathymetry, is challenging and comprises our main objective. Additionally, no large-scale catastrophic sector collapses have ever been reported in the Azores, which makes Santa Maria Island a particularly interesting target. In Santa Maria, lava flows of the two main sub-aerial volcanic complexes dip gently to the west, they are separated by a volcano-sedimentary complex lying on an unconformity dipping gently to the east, and the ages decrease to the east. From this geometry and geochronology, we infer that: (1) more than half of the early shield volcano is missing (absence of all eastern flank, summit and part of the western flank), which we interpret as a large-scale sector collapse whose scar is in part the east-dipping unconformity covered with sediments ca. 4.2 Ma old; (2) the scar was filled by a younger shield volcano that grew very rapidly (ca. 4.0-3.6 Ma); (3) a second large-scale sector collapse followed, which again spared only part of the western flank of the younger shield volcano; (4) new volcanism made of dykes and volcanic cones aligned with the arcuate collapse scar indicate that the slide may have occurred ca. 3.6 Ma ago. We conclude that Santa Maria records onshore evidence of two large-scale sector collapses.

    Full Text Available Building up a professional identity assuming a main role to teachers autonomy as well as assuming cooperation as a fundamental issue in teacher training methodology, are commonly being considered main goals for teachers professional learning, along with the new demands in the contemporaneous society and the answers to new challenges as well as the conviction of students «educability». In this paper we describe how these goals have been systematically and almost obsessively undertaken by a group of teachers in Terceira Island, Azores archipelago, Portugal, during the last ten years. A collaborative pedagogy, i.e. changing practices for student achievement as well as making their practice open to peer critique, the student-centered teachers instruction along with a democratic practice within the classroom, which they always try to improve, are the main issues which characterize the work of these professionals. The strategies adopted by this group include the formation of organized working groups where there is a truly cooperation, reflection and sharing of their practices. The learning groups are in the core of the methodology where teachers assist each other in a day-by-day routine and use an open dialogue to express their feelings, expectations and distresses about their own practices.

    2013-05-01

    Full Text Available Contending and competing geographies are often implicitly involved in archipelagic spaces. Various small island states and territories with multi-island geographies have flourishing tourism industries that presuppose an archipelagic experience: visitors are encouraged to explore and sample different island constituents of the territory. This strategy taps into different tourism niche markets, improves local value added, and shares tourism revenue beyond key nodes and urban centers. The organization of such an important economic activity however often reflects a ‘one-size-fits-all’, tightly coordinated, frequently contrived process that does not necessarily speak to the cultural and biogeographical forms of diversity that reside in the archipelago. This paper offers the notion of archipelago as a new way of rethinking problems and challenges encountered in island tourism, and then assesses the implications of this conceptualization on the representation of ‘the archipelago’ in the Azores, Portugal, and reviews what this approach means and implies for sustainable tourism policy.

  3. Felsic lavas of Terceira Island, Azores: distribution, morphology and mode of emplacement

    Terceira Island in the Azores archipelago is a remarkable example of effusive felsic volcanism. It is located in a geodynamic setting dominated by the WNW-ESE slow-spreading Terceira Rift that separates the Eurasian and Nubia plates, east of the Mid-Atlantic Ridge. Terceira differs from the other islands of the archipelago for the abundance of peralkaline felsic domes and coulees, which are the product with the largest volumetric expression (4.1 km3 DRE) in the recent eruptive history of the island (Morphological, morphometric and geological analysis provided the means to constraint the emplacement modes of these peralkaline felsic lavas. From the spatial distribution of the eruptive centres it was possible to determine the presence of extensive WNW-ESE, NW-SE and ENE-WSW alignments, suggesting that these lavas were fed from depth by dykes strongly influenced by regional stress fields, although sometimes locally subjugated by magmatic stress. Lavas from both volcanoes are peralkaline trachytes and comendites very uniform in appearance with black, scoriaceous, rubbly surfaces, ranging from almost aphyric to porphyritic. They show surface morphologies typical of viscous magmas such as ogive-like rigdes, convex in the direction of flow, high levees, lava channels and spines. The lava domes are 14-183 m in height, with radius of 50-372 m, ranging in volume from 7x104 to 4x107 m3. Coulees can reach lengths in excess of 2800 m, with widths ranging from 110 to 900 m and thicknesses of 15-70 m. The calculated volumes range from about 3x105 to 108 m3. The morphometric analysis indicate that domes follow a geometrical growth pattern of low domes (H = 0,36R), dominated essentially by an endogenous regime, although exogenous growth involving extrusions of small lobes is also present. This suggests a low magma viscosity at time of extrusion, compatible with the yield strengths (3x104 - 7x105 Pa) and plastic viscosities (3x107 - 7x1010 Pa.s) estimated and the peralkaline nature

    In order to characterize the natural coccolithophore community occurring offshore Azores and to determine their annual and interannual patterns, monthly samples were collected, from September 2010 to December 2014, in the photic zone off Terceira Island. The present study revealed a clear seasonal distribution and a considerable interannual variability of the living coccolithophore community. The highest coccolithophore abundances were observed during spring and winter months, especially due to the smaller species Emiliania huxleyi and Gephyrocapsa ericsonii. In fact, the highest biomass period was registered during April 2011, associated with enhanced abundance of the overcalcified morphotype of E. huxleyi, which was possibly influenced by subpolar waters and subsequent upwelling conditions. The highest abundances of Gephyrocapsa muellerae were recorded during June 2011 and 2014, indicating that this species characterizes the transition between the period of maximum productivity and the subsequent smoother environmental conditions, the first and the later stages of the phytoplankton succession described by Margalef, respectively. During summer to early fall, a gradual decrease of the overall coccolithophore abundance was observed, while the species richness (Margalef diversity index) increased. A subtropical coccolithophore assemblage mainly composed by Umbellosphaera tenuis, Syracosphaera spp., Discosphaera tubifera, Rhabdosphaera clavigera and Coronosphaera mediterranea indicated the presence of surface warmer waters accompanied by reduced mixing and low nutrients concentration. During late fall to winter, the coccolithophore abundance increased again with a concomitant reduction in species diversity. This is potentially linked to low sea surface temperatures, moderate nutrients concentration and surface mixed layer deepening. During 2011, colder and productive waters led to an increase in the total coccolithophore abundances. On contrary, during 2012

    Protected areas (PAs) are considered key priorities for ensuring long-term sustainability of small islands. The traditional approach of conservation versus development is currently being replaced by an approach of "win-win" relationships. During the last decades PAs have been increasingly requested to simultaneously ensure biodiversity conservation, mainstream ecosystem services into main development policies, and accounting for leisure-related revenues to sustain local and regional economies. Following this new paradigm, the Smartparks project (Planning and Management System for Small Islands Protected Areas), encompassing this study, aimed at an innovative approach for supporting the management of PAs in small islands. In this study, we propose a methodology based on Environmental Functional Analyses (EFA) to compare the potential for conservation and the potential for use of PAs that can be used not only on small islands but also in other territories. For this purpose, a set of environmental and socio-economic components was defined and selected indicators describing each component to calculate conservation and use/development functions of PAs were established. Pico Island, in the Azores archipelago (Portugal), was selected as the case study for testing the methodology. The EFA for all PAs of Pico Island was performed identifying those with more potential for conservation or for development of human activities, and also those with high levels of conflict. A total of 34 indicators was applied (assigning a value from 1 to 3) to the 22 PAs composing the INP of Pico Island: 44% were scored with a value of 1, in both ecological and social components; 22% and 29% were scored 3 in ecological and social components respectively. Social indicators were generally considered less important than environmental ones. In general, PAs presented higher values for conservation. The results further show that the potential for conservation and/or development was consistent with the

    We examined the presence of borreliae and rickettsiae bacteria in ticks from wild passerine birds on three islands of the Archipelago of the Azores, the westernmost region of Palearctic. A total of 266 birds belonging to eight species from seven families were examined on São Miguel, Santa Maria and Graciosa islands in 2013. Ticks collected from these birds consisted of 55 Ixodes frontalis (22 larvae, 32 nymphs, 1 adult female) and 16 Haemaphysalis punctata nymphs. Turdus merula and Erithacus rubecula were the birds most infested with both tick species. Three T. merula in Santa Maria were infested with 4 I. frontalis infected with Borrelia turdi. No rickettsiae were found in the ticks. We report for the first time the presence of I. frontalis and B. turdi on the Azores islands and we showed that the spatial distribution reaches further west than previously thought.

    Clenbuterol is a well-known growth promoter, illegally used in farm animals, especially in cattle. Samples collected for the screening of beta(2)-agonist residues in Portuguese Azores Islands must travel through all the nine islands until they reach Azores Central Laboratory. If any suspicious sample is detected, it must be further transported to the National Reference Laboratory in Lisbon for confirmation. As a consequence of these circumstances, samples are submitted to different transport and storage times, as well as different temperature conditions and in some cases successive freezing and thawing cycles. As clenbuterol is the most detected beta(2)-agonist growth promoter in the Portuguese Residue Monitoring Plan, studies were conducted on the stability of this compound in incurred samples (bovine liver and urine) at +4, -20 and -60 degrees C over time. Samples kept at -20 degrees C were also analyzed over time after successive freezing and thawing cycles. The analyses of clenbuterol over time were performed by gas chromatography-mass spectrometry (GC-MS) with selected ion monitoring (SIM). Clenbuterol in incurred urine and liver samples was significantly stable up to 20 weeks at -20 and -60 degrees C and after, at least, six consecutive freezings and thawings. At +4 degrees C, clenbuterol remained stable, at least until 12 weeks in urine and up to 20 weeks in liver.

    2014-02-01

    Full Text Available Graciosa is a mid-Pleistocene to Holocene volcanic island that lies in a complex plate boundary between the North American, Eurasian, and Nubian plates. Large fault scarps displace the oldest (Middle Pleistocene volcanic units, but in the younger areas recent volcanism (Holocene to Upper Pleistocene conceals the surface expression of faulting, limiting neotectonic observations. The large displacement accumulated by the older volcanic units when compared with the younger formations suggests a variability of deformation rates and the possibility of alternating periods of higher and lower tectonic deformation rates; this would increase the recurrence interval of surface rupturing earthquakes. Nevertheless, in historical times a few destructive earthquakes affected the island attesting for its seismic hazard. Regarding the structural data, two main fault systems, incompatible with a single stress field, were identified at Graciosa Island. Thus, it is proposed that the region is affected by two alternating stress fields. The stress field #1 corresponds to the regional stress regime proposed by several authors for the interplate shear zone that constitutes the Azorean segment of the Eurasia-Nubia plate boundary. It is suggested that the stress field #2 will act when the area under the influence of the regional stress field #1 narrows as a result of variations in the differential spreading rates north and south of Azores. The islands closer to the edge of the sheared region will temporarily come under the influence of a different (external stress field (stress field #2. Such data support the concept that, in the Azores, the Eurasia-Nubia boundary corresponds to a complex and wide deformation zone, variable in time.

    The Azores islands are located in the North Atlantic Ocean near a triple junction, between the African, Eurasian and North American plates, at about 1500 km from the European continent and 3900 km from the North America east coast. It is formed by nine volcanic islands and a few islets dispersed along a 600 km NW-SE direction axis. The complex geological and geodynamic setting of the Azores explains its significant seismic and volcanic activity, including eruptions and degassing processes. Important landslides triggered either by earthquakes, volcanic eruptions, extreme meteorological conditions and/or coastal erosion processes frequently affect the islands, and tsunamis related with earthquakes and landslides were reported to have occurred in the past. The national curriculum for the school subject of Biology and Geology sees the Azores as a laboratory for the earth sciences and many topics revolve around it. For these reasons, we organised a field trip to the island of São Miguel, with pupils of the 11th grade who live in the Portuguese mainland, in a region that is geologically very different. During the six days of this trip, we attended training sessions in the Centre for Volcanology and Geological Risks Assessment (CVARG) of the Azores University. This multidisciplinary research unit organises activities around the prediction and prevention of disasters and natural hazards in the fields of volcanology and correlated phenomena, including volcanic eruptions, earthquakes, volcanic fumes, air pollution and water contaminants, landslides, floods and tsunamis, among others. The pupils explored volcanic calderas, lava caves, fumaroles and hot springs. They also collected and analysed extremophile bacteria that live in local hot springs.

    Azores islands of the Eastern and Central groups are located at the triple junction of the American, Eurasian and Nubian plates inducing a large number of low magnitude earthquakes. Since its settlement in the 15th century, 33 earthquakes with intensity ≥ VII have caused severe damage and high death toll. The most severe ones occurred in 1522 at São Miguel Island with a maximum MM intensity of X; in 1614 at Terceira Island (X) in 1757 at São Jorge Island (XI); 1852 at São Miguel Island (VIII); 1926 at Faial Island (Mb 5.3-5.9); in 1980 at Terceira Island (Mw7.1) and in 1998 at Faial Island (Mw6.2). The analysis of the Probabilistic Seismic Hazard Assessment (PSHA) were carried out using the classical Cornell-McGuire approach using seismogenic zones recently defined by Fontiela et al. (2014). We create a new earthquake catalogue merging local and global datasets with a large time span (1522 - 2016) to calculate recurrence times and maximum magnitudes. In order to reduce the epistemic uncertainties, we test several ground motion prediction equations in agreement with the geological heterogeneities typical of young volcanic islands. Probabilistic seismic hazard maps are proposed for 475 and 975 years returns periods as well as hazard curves and uniform hazard spectra for the main cities. REFERENCES: Fontiela, J. et al., 2014.

    Quaternary vertebrate fossils, most notably mammoth remains, are relatively common on the northern Channel Islands of California. Well-preserved cranial, dental, and appendicular elements of Mammuthus exilis (pygmy mammoth) and Mammuthus columbi (Columbian mammoth) have been recovered from hundreds of localities on the islands during the past half-century or more. Despite this paleontological wealth, the geologic context of the fossils is described in the published literature only briefly or not at all, which has hampered the interpretation of associated 14C ages and reconstruction of past environmental conditions. We recently discovered a partial tusk, several large bones, and a tooth enamel plate (all likely mammoth) at two sites on the northwest flank of San Miguel Island, California. At both localities, we documented the stratigraphic context of the fossils, described the host sediments in detail, and collected charcoal and terrestrial gastropod shells for radiocarbon dating. The resulting 14C ages indicate that the mammoths were present on San Miguel Island between ∼20 and 17 ka as well as between ∼14 and 13 ka (thousands of calibrated 14C years before present), similar to other mammoth sites on San Miguel, Santa Cruz, and Santa Rosa Islands. In addition to documenting the geologic context and ages of the fossils, we present a series of protocols for documenting and reporting geologic and stratigraphic information at fossil sites on the California Channel Islands in general, and in Channel Islands National Park in particular, so that pertinent information is collected prior to excavation of vertebrate materials, thus maximizing their scientific value.

    2016-05-01

    Full Text Available Establishing Protected Areas (PAs is considered one of the most appropriate ways to conserve nature and cultural landscapes. However, conservation constraints can generate social conflicts, especially at a local level. In small islands (SIs, local conflicts may escalate due to an increase in competition for limited space and resources. Pico island in the Azores Archipelago (Portugal, part of the Outermost European region, was considered a good case to study conservation-development conflicts due to the amount of designated protected land (> 35% of its surface and the approval of a new Azorean PA network in 2007. This paper presents a new approach to understanding and mapping local conflicts within PAs in SIs by integrating qualitative data and spatially explicit information. This research takes stock of the benefits, needs and constraints related to Pico Natural Park as perceived by local stakeholders through face-to-face semi-structured interviews; it subsequently identifies and transposes the conflicts distilled from stakeholder discourse into spatially representative visual maps via GIS. Research outcomes show that PAs are perceived mainly as constraints to local development, showing inconsistency between local expectations and regional conservation policy. This highlights the importance of including public participation processes prior to any implementation of conservation strategies. The proposed method provides a springboard towards effective conflict management for PAs on Pico island, showing a relatively low-cost and straightforward approach to minimising future local conflicts which could be adapted to other similar Outermost European regions and SIs.

    Full Text Available This paper discusses the touristic asset of the Azores Lake Gardens, analysing landscape transformations and testing the currently visual preferences of local people (C. Steinitz 1990; C. Castel-Branco et al. 2011. On the volcanic Islands of the Azores lake gardens built in the 19th century in the old craters of Furnas and Sete Cidades at S. Miguel Island had a naturally picturesque setting. Since then, they became cultural landscapes; encompassing extensive woodland gardens and romantic buildings (I. Albergaria 2000, these Lake Gardens have turned into iconic symbols of local identity becoming the subject of representations as part of the tourist attractions of the island. Albeit the high standards of environmental and landscape quality of the Azores, promoted in international publicity as the most sustainable tourist destination in the world (Global Sustainable Tourism Review, 2014, these two lakes are polluted due to an intensive dairy practice impact and became eutrophic. A long term goal of the project envisions to protect these lakes and landscapes to promote them through cultural landscape management and spatial planning within a sustainable tourism framework.

    2014-06-01

    Full Text Available Pinna rudis is known as one of the biggest fan mussels in the Azores, reaching a length of up to 80cm. The specimens are generally found attached by numerous byssus threads, with their pointed anterior ends buried vertically in the substratum (mud, sandy mud or gravel. However, currently there is a notorious lack of basic knowledge about this species, with no specific studies available in the literature. The objective of the present work was to study the occurrence of Pinna rudis in the coast of Terceira Island, by analysing the spatial distribution of the individuals, and investigate the symbiotic association with the shrimp Pontonia pinnophylax. Along the south coast of Terceira Island, 23 dives in 13 sites were performed using 30 meters transects. The dives were made from August to October 2004, limited by meteorological conditions. The length of each pinnid was measured in situ, and above the sediment, to avoid unnecessary removal. During the study period, 28 P. rudis were observed with a length range from 10 to 30cm. The majority measured about 10 to 15cm. The occurrence of P. rudis was not the same at the different sites selected, occurring mainly in small patches of sand in rocky bottoms. Only solitary individuals were observed. No correlation between the length of the animals and the depth of their occurrence was detected. The shrimp Pontonia pinnophylax was found living within the largest bivalves and at deeper depths. The occupancy rate of Pinna rudis by Pontonia pinnophylax was 57% (containing one or two shrimps. It is believed that the life cycles of these two species may be linked. The exact relationship between these two species remains unclear and needs to be studied experimentally; however it is believed that this is a mutualistic association.

    The Pico Island constitutes the easternmost sub-aerial domain of a steep WNW-ESE volcanic ridge, which has developed within the Nubia-Eurasia diffuse plate boundary (Azores Triple Junction). The island comprises three volcanic systems, from older to younger: the Topo Volcano, the Fissural System, and the Pico Stratovolcano. From a high-resolution Digital Elevation Model (10 m), and new bathymetric, stratigraphic, structural, and high-precision K-Ar data, we reconstruct the main successive stages of growth and partial destruction of the island over the last 200 kyr. We especially concentrate on the central sector of the island, which has recorded gradual movements through slumping and catastrophic flank collapses since ca. 130 kyr. The remmants of the Topo Volcano are partly exposed on Pico's SE flank, and are here dated between 186 ± 5 and 115 ± 4 ka. Topo was significantly destroyed by N- and S-directed large-scale flank collapses between ca. 125 and 70 ka. On Pico's N flank, collapse seems to have removed all the unstable material, but in the S the collapse structure is composite, including a major flank collapse and a remnant slump complex that is still active. A first episode of deformation occurred between ca. 125 and 115 ka along the master fault of the slump. Between ca. 115 and 69 ka, most of the unstable material was removed by a major flank collapse, leaving behind a still considerable volume of unstable material that comprises the active slump. This first collapse was catastrophic and generated a large debris deposit recognized on the high-resolution bathymetry, with a minimum run-out of ca. 17 km. The scar was partially filled by volcanic products erupted from volcanic cones developed within the slump depression, and possibly also from the early WNW-ESE Fissural System. Subsequent deformation in the slump area affected in part the filling units, leading to the individualization of secondary curved faults. Younger volcanic products have gradually

    The Terceira rift is a oblique ultra-slow spreading system where a transtensive regime results from differential movement between Eurasian and African plates. So far no classical ridge segmentation pattern has here been observed. The predominant morphological features are fault controlled rhombic shaped basins and volcanism related morphologies like circular seamounts and volcanic ridges. We present SIMRAD EM300 (bathymetry + backscatter) images acquired over one of these ridges located SE of Terceira Island, during the SIRENA cruise (PI J. Goslin), which complements previous TOBI mosaics performed over the same area during the AZZORRE99 cruise (PI M. Ligi). The ridge presents a NW-SE orientation, it is seismically active (a seismic crisis was documented in 1997) and corresponds to the southern branch of a V shape bathymetric feature enclosing the Terceira Island and which tip is located west of the Island near the 1998 Serreta ridge eruption site. NE of the ridge, the core of the V, corresponds to the North Hirondelle basin. All this area corresponds mainly to Brunhes magnetic epoch. The new bathymetry maps reveal a partition between tectonic processes, centred in the ridge, and volcanism present at the bottom of the North Hirondelle basin. The ridge high backscatter surface is cut by a set of sub-parallel anastomosed normal faults striking between N130º and N150º. Some faults present horse-tail terminations. Fault splays sometimes link to neighbour faults defining extensional duplexes and fault wedge basins and highs of rhombic shape. The faulting geometry suggests that a left-lateral strike slip component should be present. The top of the ridge consists on an arched demi-.horst, and it is probably a volcanic structure remnant (caldera system?), existing prior to onset of the tectonic stage in the ridge. Both ridge flanks display gullies and mass wasting fans at the base of the slope. The ridge vicinities are almost exclusively composed of a grayish homogeneous

    Full Text Available Fluid geochemistry monitoring in the Azores involves the regular sampling and analysis of gas discharges from fumaroles and measurements of CO2 diffuse soil gas emissions. Main degassing areas under monitoring are associated with hydrothermal systems of active central volcanoes in S. Miguel, Terceira and Graciosa islands. Fumarole discharge analysis since 1991 show that apart from steam these gas emissions are CO2 dominated with H2S, H2, CH4 and N2 in minor amounts. Mapping of CO2 diffuse soil emissions in S. Miguel Island lead to the conclusion that some inhabited areas are located within hazard-zones. At Furnas village, inside Furnas volcano caldera, about 62% of the 896 houses are within the CO2 anomaly, 5% being in areas of moderate to high risk. At Ribeira Seca, on the north flank of Fogo volcano, few family houses were evacuated when CO2 concentrations in the air reached 8 mol%. To assess and analyse the CO2 soil flux emissions, continuous monitoring stations were installed in S. Miguel (2, Terceira and Graciosa islands. The statistical analysis of the data showed that some meteorological parameters influence the CO2 flux. The average of CO2 flux in S. Miguel stations ranges from 250 g/m2/d at Furnas volcano to 530 g/m2/d at Fogo volcano. At Terceira Island it is about 330 g/m2/d and at Graciosa 4400 g/m2/d.

  2. Magnetic study of the Furnas caldera (Azores

    Full Text Available A local ground magnetic study of the Furnas caldera (S. Miguel Island, Azores has provided new insight into the magnetic structure of this volcano. Analysis of the data comprised removal of the IGRF, reduction to the pole, pseudogravity integration and upward continuation. Also, a spectral method was applied to estimate the depth to the magnetic sources, as well as a 2.5D forward modelling technique. Magnetic properties obtained at the laboratory for some representative sample rocks were considered in the modelling process. The most relevant features are the existence of an important negative anomaly inside the caldera and of an intense positive anomaly to the south of the coast. The former points out a decrease in the magnetization of the caldera filling materials with respect to the surrounding rocks, which could be explained as the result of post-eruption processes such as hydrothermal alteration. This is expected as Furnas has an active hydrothermal system probably related with a magmatic reservoir at high temperature. The positive anomaly suggests the existence of a strongly-magnetized body beneath the south coast.

    Full Text Available Downy mildew is one of the most economically important disease affecting vine production in Terceira island, Azores. By its incidence, frequency and quantity of pathogens, supported with favourable temperate humid climate conditions, this disease is difficult to control in terms of sustainable integrated plant protection policy. The objectives of INTERFRUTA project were to determine the incidence of the disease, to better understand it and to adopt an adequate forecasting model with necessary adjustments to predict the disease appearance and its in-time integrated plant protection control measures. Plasmopara viticola was directly observed in two weeks time periods on seven representative vineyards at different altitudes. Three of the monitored plots were established during study inside one plantation. Incidence was registered as result of visual symptoms in percentage, where 10% of plants in each vineyard were observed. Seasonal evolution of the disease was studied in one of the wine producing area.O Míldio é uma das doenças que mais afecta a vinha, na ilha Terceira, Açores. É uma doença fúngica de difícil controlo, pela sua incidência e frequência de aparecimento. Os objectivos do projecto INTERFRUTA II foram determinar a incidência desta doença para melhorar o conhecimento sobre esta e adoptar e validar um modelo matemático adequado à previsão do aparecimento da doença de modo a permitir a aplicação de medidas de protecção integrada. A evolução do míldio foi acompanhada em sete parcelas de vinha, da área vitivinícola dos Biscoitos, através da observação visual de folhas. Numa das parcelas, três dos talhões não foram tratados para servirem de controlo. Em cada parcela foram observadas 10% das plantas, tendo sido registada a percentagem de plantas com sintomas visuais da presença de míldio.

    There is evidence that the CCR5-delta32 mutation confers protection against HIV-1 infection to homozygous individuals. It is believed that this mutation spread through Europe with the Vikings and that it has been subjected to positive selection, leading to a high frequency in Europe (approximately 10%). We carried out the present study to determine the 32-bp deletion allele and genotype frequencies of the CCR5 gene (CCR5-delta32) in the Atlantic island populations of Madeira, the Azores, Cabo Verde, and São Tomé e Principe. These Atlantic archipelagos were all colonized by the Portuguese in the 15th and 16th centuries, but the latter two received most of their settlers from the West African coast. The frequency of the CCR5-delta32 mutation varies between 0% in São Tomé e Príncipe and 16.5% in the Azores. The Azores Islands have one of the highest frequencies of homozygotes found in Europe (4.8%). There are significant differences (P < 0.05) between some of these populations, for example, between São Tomé e Príncipe and Cabo Verde, and even within populations (e.g., Portugal, Madeira, and the Azores).

Miguel Island. The rupture process of these earthquakes has been studied from body wave inversion of broad band data at telesesimic distances. Results obtained shown normal faulting for both shocks, with planes oriented in NW-SE direction, with focus at shallow depth (10 km and 6 km respectively). The slip distribution over the fault plane (152/44/-88) shows for the 05-04-07 event, the rupture propagating downward and a duration of 12s for the source time function. For the 07-04-07 event, the slip distribution over the fault plane (125/52/-81) shows de rupture propagating downward and duration of 10s for the STF. From these results we have estimated the static Coulomb stress change. We find that the static stress change caused by the 5 April event is higher, about 2 bar at epicenter the location of the second event (April 7), triggering the second rupture. Locations of aftershocks do not agree well with areas of increased Coulomb failure stress, which can be explained by the complexities of the rupture process oy by uncertainties at the hypocerter location

    Global homogenization of biota is underway through worldwide introduction and establishment of non-indigenous (exotic) species. Organisms fouling ship hulls are continually in transit and can affect communities through biodiversity loss and serious damage to economy and public health. In the Azores, for the first time, underwater alien species prospection was conducted in marinas and recreational harbours, at São Miguel Island. Populations of three locally previously unknown barnacle species were found: Amphibalanus amphitrite, Amphibalanus eburneus and Perforatus perforatus. These species account for the more than 50% of alien barnacles worldwide that belong to Balanidae family. Hence, some considerations about morphology and life cycle of this family are advanced, discussed and related to their invasive potential.

    We present multibeam and high-resolution reflection seismic data which elucidate the architecture of three submarine intraplate volcanoes located in the southern Azores Archipelago. Data have been collected during RV Meteor cruise M113 in 2015. Four GI-Guns served as the seismic source. The digital streamer comprised 144 channels distributed over a length of 600 m. The three cones are situated in a depth down to 2300 m with heights varying between 200 m and 243 m, an average diameter of 1360 m and an average slope angle of ca. 22°. All three circular cones are surrounded by a circular channel. These features, previously named "fried eggs" were previously interpreted as impact crater (Dias et al., 2009). A comparison with nearby submarine volcanoes close to São Miguel island (Weiß et al., 2015), however, strongly suggests a volcanic origin. The seismic data indicate that the volcanic cones formed on top of a ca. 100 m thick pelagic succession covering the igneous basement. Magma ascent deformed the volcanic basement, displaced the pelagic sediments and a first eruption phase formed a small, seismically transparent volcanic cone. Further eruptions created a volcanic cone with rather transparent reflections within the inferior region changing to strong reflection amplitudes with a chaotic pattern in the superior area. Compared to the igneous basement internal reflection amplitudes are mainly weak. The seismic transparency and slope angle exclude the presence of effusive rocks, since lavas usually create strong impedance contrasts. A comparison of the seismic characteristics with those from submarine Kolumbo volcano (Hübscher et al., 2015) suggests volcaniclastic lithologies from explosive eruptions. The circular channel around the volcanic cone shows the characteristics of a moat channel created by bottom currents.

    Calodium hepaticum (Syn. Capillaria hepatica) is a zoonotic liver nematode of mammals distributed worldwide. Rodents are believed to be the main reservoirs of this nematode. In this paper, prevalence of the parasite was analyzed in liver histological sections from 51 house mice (Mus musculus) caught in human-inhabited houses, from two localities (Furnas and Rabo de Peixe) on São Miguel island from the Azores archipelago (Portugal). Mean prevalence of infection was 19.6%, with 33.3% prevalence in Furnas and 4.1% in Rabo de Peixe (P=0.07). No significant differences were found between the prevalence of infection and the age, body weight and the sex of mice. Hepatic lesions found were either acute and/or chronic stage and consisted of moderate to severe multifocal pyogranulomatous hepatitis with encapsulated eggs with typical bipolar plugs and moderate to severe necrotizing hepatitis consistent with larva tracks. Periportal inflammatory infiltration, hepatocyte regeneration and bile duct hyperplasia were also noted. In most cases, hepatic lesions occupied more than 50% of the liver, but despite severe lesions, in some mice, no signs of hepatic failure were noticed. The high rate of infection found in the present study suggests that house mice are an important reservoir for this parasite in the Azores and could have a role in human transmission.

    Fogo volcano is an active central volcano, with a lake filled caldera, in the central part of Sao Miguel Island, Azores, whose current activity is limited to fumarolic and hydrothermal activity. It is affected by important active tectonic structures, with extremely high seismic activity and micro-seismicity concentrated in very frequent swarms. A recurrent feature of the seismicity observed in volcanic regions is the occurrence of seismic families, whose origins can be attributed to the same source mechanism, acting in the same small rock volume. Doublets/multiplets were identified in this study within a catalogue of small magnitude (usually lack of any main-shock after-shock sequence and organized migration of the hypocenters. This is suggestive of a very heterogeneous stress field. Vp/Vs is found to be lower than usually observed in volcanic areas, an occurrence likely related to the presence of fluid associated with the geothermal system (Saccorotti et al., 2004). Taken together, these two observations suggest that fluid migration/pressurization play a major role in triggering the recorded seismicity. The geothermal fluids around Fogo massif have been identified as derived from meteoric water, which infiltrates through Fogo Lake and the volcano flank and flows from south to north on the northern flank (Carvalho, 1999). These results point to the important role played by rainfall in triggering seismicity at Sao Miguel, possibly through pressure changes at depth in response to surface rain and/or interaction with the geothermal system.

    2015-07-01

    Full Text Available Waters from natural sources of the São Miguel Island in the Azores archipelago have been investigated regarding their corrosive action on metallic materials. The corrosive and encrusting characteristics of the waters have been established in terms of relevant chemical parameters (namely pH, conductivity, total dissolved solids (TDS, and concentrations of bicarbonate, calcium, magnesium, chloride, and sulfate ions and their temperature by using Langelier, Ryznar, Puckorius and Larson–Skold indexes. The validity of this methodology has been tested by measuring the corrosion rates of various metals exposed to various waters using electrochemical methods. The materials of industrial interest under investigation were carbon and galvanized steel, zinc, 304 and 316L grade stainless steels, brass, and Cr–Ni alloys. The greater aggressiveness of these waters was found for the less noble materials, and they experienced high corrosion rates.

    The AD 1761 eruption on Terceira was the only historical subaerial event on the island and one of the last recorded in the Azores. The eruption occurred along the fissure zone that crosses the island and produced a trachybasalt lava flow and scoria cones. Small comenditic trachyte lava domes (known as Mistérios Negros) were also thought by some to have formed simultaneously on the eastern flank of Santa Bárbara Volcano. Following a multidisciplinary approach, we combined geological mapping, paleomagnetic, petrographic, mineral and whole-rock geochemical and structural analyses to study this eruption. The paleomagnetic dating method compared geomagnetic vectors (directions and intensities) recorded by both the AD 1761 lava flow and Mistérios Negros domes and revealed that the two events were indeed coeval. Based on new data and interpretation of historical records, we have accordingly reconstructed the AD 1761 eruptive dynamics and distinguished three phases: (1) a precursory phase characterized by decreased degassing in the fumarolic field of Pico Alto Volcano and a gradual increase of seismic activity, which marked the intrusion of trachybasalt magma; (2) a first eruptive phase that started with phreatic explosions on the eastern flank of Santa Bárbara Volcano, followed by the inconspicuous effusion of comenditic trachyte (66 wt% SiO2), forming a WNW-ESE-oriented chain of lava domes; and (3) a second eruptive phase on the central part of the fissure zone, where a Hawaiian to Strombolian-style eruption formed small scoria cones (E-W to ENE-WSW-oriented) and a trachybasalt lava flow (50 wt% SiO2) which buried 27 houses in Biscoitos village. Petrological analyses show that the two batches of magma were emitted independently without evidence of interaction. We envisage that the dome-forming event was triggered by local stress changes induced by intrusion of the trachybasalt dyke along the fissure zone, which created tensile stress conditions that promoted ascent

    Domoic acid is a glutaminergic neurotoxin produced by marine algae such as Pseudo-nitzschia australis. California sea lions (Zalophus californianus) ingest the toxin when foraging on planktivorous fish. Adult females comprise 60% of stranded animals admitted for rehabilitation due to acute domoic acid toxicosis and commonly suffer from reproductive failure, including abortions and premature live births. Domoic acid has been shown to cross the placenta exposing the fetus to the toxin. To determine whether domoic acid was playing a role in reproductive failure in sea lion rookeries, 67 aborted and live-born premature pups were sampled on San Miguel Island in 2005 and 2006 to investigate the causes for reproductive failure. Analyses included domoic acid, contaminant and infectious disease testing, and histologic examination. Pseudo-nitzschia spp. were present both in the environment and in sea lion feces, and domoic acid was detected in the sea lion feces and in 17% of pup samples tested. Histopathologic findings included systemic and localized inflammation and bacterial infections of amniotic origin, placental abruption, and brain edema. The primary lesion in five animals with measurable domoic acid concentrations was brain edema, a common finding and, in some cases, the only lesion observed in aborted premature pups born to domoic acid-intoxicated females in rehabilitation. Blubber organochlorine concentrations were lower than those measured previously in premature sea lion pups collected in the 1970s. While the etiology of abortion and premature parturition was varied in this study, these results suggest that domoic acid contributes to reproductive failure on California sea lion rookeries.

    Noble gas data (He and Ne) on olivine phenocrysts obtained from Azores’ lavas sampled along the Terceira Rift will be presented in this work. The Terceira Rift is considered as one of the slowest spreading system in the world (Vogt & Jung, 2004). Lava samples were collected inland at S. Miguel, Terceira, Graciosa, Pico and Faial Islands as well at sea at D. João de Castro Bank and south Hirondelle basin, the latter being sampled by the ROV cruises in 2008 and 2009. Noble gas data were analyzed in the Noblesse mass spectrometer housed at the IPGP. The most primitive He isotopic ratios were obtained from Pico, Terceira and Hirondelle olivines. Most Ne isotopic ratios are similar to the present-day atmosphere, but distinct 20Ne/22Ne ratios were found for the majority of submarine samples and also Pico and Faial Islands, defining mixing lines with the atmospheric end-member with slopes greater than that defined from MORB lavas. The He-Ne systematics shows that most of the new noble gas data fit in a mixing model between a dominant MORB-type mantle source and a relatively primitive mantle source related with the regional Azores component. However, data from the D. João de Castro Bank argue for the presence of a radiogenic He end-member distinct from MORB. References: Vogt, P. & Jung W. (2004). Earth Planet. Sci. Lett., 218: 77 90.

    The present study deals with the development of systematic conservation planning as management instrument in small oceanic islands, ensuring open systems of governance, and able to integrate an informed and involved participation of the stakeholders. Marxan software was used to define management areas according a set of alternative land use scenarios considering different conservation and management paradigms. Modeled conservation zones were interpreted and compared with the existing protected areas allowing more fused information for future trade-outs and stakeholder's involvement. The results, allowing the identification of Target Management Units (TMU) based on the consideration of different development scenarios proved to be consistent with a feasible development of evaluation approaches able to support sound governance systems. Moreover, the detailed geographic identification of TMU seems to be able to support participated policies towards a more sustainable management of the entire island.

    Full Text Available A região dos Biscoitos na ilha Terceira, nos Açores, é mundialmente conhecida pela vinha em curraletas destinada à produção de Vinhos Licorosos de Qualidade Produzidos em Região Demarcada (VLQPRD. As castas predominantes são Verdelho branco e Verdelho roxo mas também estão presentes Terrantez, Arinto e Boal branco. Um dos objectivos do projecto Interfruta-II é avaliar o actual estado sanitário destas videiras em relação aos principais vírus. Assim, em Fevereiro de 2006, foi realizada uma prospecção em sete vinhas tendo sido analisados por ELISA os vírus GLRaV-1, GLRaV-2, GLRaV-3, GLRaV-7, GFLV, ArMV, GVA, GVB e GFkV. Os resultados são analisados por casta e vinha. No global mostram que a infecção por GLRaV-3 atinge os 100% e que a infecção por um ou dois Nepovirus é superior a 50%. Os restantes vírus foram detectados em menor percentagem. Existe elevada percentagem de infecções mistas. Atendendo ao prejudicial efeito qualitativo e/ou quantitativo das infecções detectadas, é apresentada uma estratégia de intervenção fitossanitária pretendendo contribuir para a recuperação da vinha nos Biscoitos.At Terceira island in Azores, the region Biscoitos is well known by its vineyards in typical “curraletas”. The grapevines are for the production of VLQPRD (i.e. Quality Liquorus Wines Produced in Demarcated Region. The predominant varieties are Verdelho branco and Verdelho roxo but also Terrantez, Arinto and Boal branco are present. One of the objectives of the project Interfruta-II is the evaluation of the actual sanitary status of those grapevines in relation to the main viruses. Therefore, in February 2006, a survey was done in seven vineyards evaluating by ELISA the virus GLRaV-1, GLRaV-2, GLRaV-3, GLRaV-7, GFLV, ArMV, GVA, GVB and GFkV. The results are analyzed by vineyard and by variety. In general they show that infection by GLRaV-3 is 100% and that infection by one or two Nepovirus is above 50%. The other

    We report on 33 new paleomagnetic directions obtained from 16 lava flows emplaced in the last 3 ka on São Miguel, the largest island of the Azores. The data provide 27 directions from historical or 14C dated flows which, together with 6 directions previously gathered from the same flows by Johyson et al., (1998), yield the first paleomagnetic record of the last 3 ka from the Atlantic Ocean. Within-flow directions are consistent, suggesting that inclination swings from 60° to 25° and declination changes between -10° to 20° reflect variations in the geomagnetic field over the last 3 ka. To a first approximation, the declination record is consistent with predictions from CALS3k.4 and gufm1 global field models. Conversely, inclination values are lower than model predictions at two different ages: 1) four different sites from the 1652 AD flow yield I=48° instead of I=63° predicted by gufm1; 2) data from several flows nicely mimic the inclination minimum of 800-1400 AD, but inclination values are lower by ca. 10° than CALS3k.4 model predictions. By interpolating a cubic spline fit on declination / inclination versus age data, we tentatively infer the directional evolution of the geomagnetic field at the Azores from 1000 BC to 1600 AD.The obtained curve shows three tracks in virtual overlap during the 1000-800 BC, 800-500 BC, and 400-700 AD time spans; Cubic spline interpolation of flow mean declinations (a) and inclinations (b) versus respective calendar ages; c) directions derived every 100 years from cubic spline interpolation, superimposed on paleomagnetic directions (and relative confidence cones) from three loosely-dated flows (Fig. 1). For ages older than 750 AD the fit line is dashed, as it is constrained by a limited number of data. Vertical error bars for declination and inclination data are α95 /cos(I) and α95 values, respectively

  3. Historical tsunami in the Azores archipelago (Portugal)

    Because of its exposed northern mid-Atlantic location, morphology and plate-tectonics setting, the Azores Archipelago is highly vulnerable to tsunami hazards associated with landslides and seismic or volcanic triggers, local or distal. Critical examination of available data - written accounts and geologic evidence - indicates that, since the settlement of the archipelago in the 15th century, at least 23 tsunami have struck Azorean coastal zones. Most of the recorded tsunami are generated by earthquakes. The highest known run-up (11-15 m) was recorded on 1 November 1755 at Terceira Island, corresponding to an event of intensity VII-VIII (damaging-heavily damaging) on the Papadopolous-Imamura scale. To date, eruptive activity, while relatively frequent in the Azores, does not appear to have generated destructive tsunami. However, this apparent paucity of volcanogenic tsunami in the historical record may be misleading because of limited instrumental and documentary data, and small source-volumes released during historical eruptions. The latter are in contrast with the geological record of massive pyroclastic flows and caldera explosions with potential to generate high-magnitude tsunami, predating settlement. In addition, limited evidence suggests that submarine landslides from unstable volcano flanks may have also triggered some damaging tsunamigenic floods that perhaps were erroneously attributed to intense storms. The lack of destructive tsunami since the mid-18th century has led to governmental complacency and public disinterest in the Azores, as demonstrated by the fact that existing emergency regulations concerning seismic events in the Azores Autonomous Region make no mention of tsunami and their attendant hazards. We suspect that the coastal fringe of the Azores may well preserve a sedimentary record of some past tsunamigenic flooding events. Geological field studies must be accelerated to expand the existing database to include prehistoric events

    Rabbit haemorrhagic disease virus 2 (RHDV2) is widespread in several countries of Western Europe, but it has not been introduced to other continents. However, between late 2014 and early 2015, the presence of RHDV2 was confirmed outside of the European continent, in the Azores, initially in the islands of Graciosa, Flores, S. Jorge and Terceira. In this study we report the subsequent detection of RHDV2 in wild rabbits from the islands of Faial, St. Maria and S. Miguel, and display the necropsy and microscopic examination data obtained, which showed lesions similar to those induced by classical strains of RHDV, with severe affection of lungs and liver. We also disclose the result of a genetic investigation carried out with RHDV2 positive samples from wild rabbits found dead in the seven islands. Partial vp60 sequences were amplified from 27 tissue samples. Nucleotide analysis showed that the Azorean strains are closely related to each other, sharing a high genetic identity (>99.15%). None of the obtained sequences were identical to any RHDV2 sequence publically known, hampering a clue for the source of the outbreaks. However, Bayesian and maximum likelihood phylogenetic analyses disclosed that Azorean strains are more closely related to a few strains from Southern Portugal than with any others presently known. In the analysed region comprising the terminal 942 nucleotides of the vp60 gene, four new single nucleotide polymorphisms (SNP) were identified. Based on the present data, these four SNPs, which are unique in the strains from Azores, may constitute putative molecular geographic markers for Azorean RHDV2 strains, if they persist in the future. One of these variations is a non-synonymous substitution that involves the replacement of one amino acid in a hypervariable region of the capsid protein.

    The variability of North Atlantic tropical storms has been the focus of several studies. Duration and seasonality has been attributed to a number of climate patterns and processes such as El Niño-Southern Oscillation, Atlantic Meridional Mode, African easterly waves, and atmospheric Rossby waves, but their tracks have been widely related to the North Atlantic Oscillation. Several authors have pointed out an increase and track shifting of North Atlantic tropical cyclones since 1995 with increased probability of these turning north far away from the North American continent. However, this cannot be regarded as an infrequent phenomenon as most proxy records from the Atlantic North have shown the existence of similar patterns in the past. Sao Miguel Island (Azores archipelago, Portugal) is settled in the middle of the Atlantic Ocean. This location makes this island an excellent natural laboratory to record shifts on North Atlantic tropical storms tracks that can reach the archipelago as low intensity hurricanes (e.g. Nadine in 2012) or downgraded to tropical storm (e.g. Grace in 2009). In the present work, lake sediment records have been used as a proxy sensor of tropical storms. Lagoa Azul is located inside Sete Cidades volcanic caldera and its catchment is characterized by stepped and forested caldera walls. Tropical storms and heavy rainfalls produce a flashy and substantial enhancement in the erosion of the catchment, increasing the sediments reaching the lake by rockfalls deposits (in littoral zones) and flood events deposits (in offshore zones). These flood events can be recognized in the sedimentary record as lobe deposits dominated by terrestrial components. It can be found in the sedimentary record and the bathymetry. Instrumental meteorological data and historical records have been compiled to reconstruct the most recent history of the North Atlantic tropical storms that have landed or affected the Sao Miguel Island (Andrade et al., 2008). In addition, a 1

    Full Text Available Nos Açores a produção de beterraba sacarina com fim industrial é exclusiva da ilha de S. Miguel onde, ao longo do último século, tem ocupado áreas com altitude até 300 metros e declives inferiores a 7%. A área variou entre 3000 hectares na década de sessenta e 200 hectares actualmente. A produtividade é variável situando-se entre as 20 e as 90 toneladas por hectare. Nos Açores a SINAGA é responsável pela transformação e distribuição dos produtos da beterraba. Com base num modelo de programação linear que estima o comportamento dos agricultores dos Açores foi possível concluir que o preço da beterraba influencia a quantidade de beterraba produzida, enquanto o preço do leite tem uma influência reduzida; que o maior efeito no aumento de produção é conseguido com o aumento de área mobilizável para a cultura o que só é possível com a redefinição do apoio técnico ao maneio da cultura.In the Azores the production of sugar beet for industrial uses is exclusive of the island of S. Miguel where along the last century it has occupied areas up to 300 meters and slopes inferior to 7 %. The used area varied between 3000 hectares in the sixties and 200 hectares at present. The productivity is variable being situated between 20 and 90 tons per hectare. In the Azores the SINAGA is responsible for the transformation and distribution of the products of the sugar beet. Using a linear programming model to explain the behaviour of farmers in the Azores it was possible to conclude that the price of sugar beet influences the quantity produced of beetroot while the price of the milk has a reduced influence; and that the biggest effect in the increase of production is got by the increase of cultivable area and with technical support.

    Full Text Available The archipelago of the Azores is like an oasis in the middle of the Atlantic Ocean. Surrounded by deep waters, those islands are a “must stop” place for every traveler, including, of course, cetaceans. Around the archipelago more than 24 different species of whales and dolphins can be seen. Some of them are resident such as the common dolphin or the emblematic sperm whale. But others are seasonal or sporadic, such as the spotted dolphin or the big baleen whales. The aim of this study is to assess the temporal distribution of the baleen whales sighted off Azores. We analyzed data gathered off the south coast of São Miguel (Azores from 2006 to 2013 from whale watching vessels. The whale watching company is located in Ponta Delgada and it works all throughout the year, always when the weather, the sea state and the number of tourists allow doing it. In Azores, whale watching companies use to locate cetaceans from land, with specialized lookouts spotting the animals from strategic points on the shore (as whalers did. These lookouts use powerful binoculars to locate the animals, and then give instructions to the boats to get to them. Once there, the boat registers date, hour, sea state, visibility, position (GPS, species, number of individuals, number of adults, juveniles and calves, behavior, association with other species and if there are other boats in the area. Photos are taken whenever it is possible and they are analyzed when the quality is good enough to distinguish natural marks and shapes. Most of the photos used in this study were taken in the last 5 years. Photo-Id catalogues were created for blue whales, fin whales and humpback whales. Data collected are more complete and frequent since 2009. In this case we have analyzed a total of 7691 sightings, belonging to 20 different species of cetaceans, 14 Odontoceti and 6 Mysticeti. In the latter group we recorded 491 sightings. The three most sighted Mysticeti species were the three great

    Okadaic acid and its analogues are potent phosphatase inhibitors that cause Diarrheic Shellfish Poisoning (DSP) through the ingestion of contaminated shellfish by humans. This group of toxins is transmitted worldwide but the number of poisoning incidents has declined over the last 20 years due to legislation and monitoring programs that were implemented for bivalves. In the summer of 2012 and 2013, we collected a total of 101 samples of 22 different species that were made up of benthic and subtidal organisms such echinoderms, crustaceans, bivalves and gastropods from Madeira, São Miguel Island (Azores archipelago) and the northwestern coast of Morocco. The samples were analyzed by UPLC-MS/MS. Our main objective was to detect new vectors for these biotoxins. We can report nine new vectors for these toxins in the North Atlantic: Astropecten aranciacus, Arbacia lixula, Echinaster sepositus, Holothuria sanctori, Ophidiaster ophidianus, Onchidella celtica, Aplysia depilans, Patella spp., and Stramonita haemostoma. Differences in toxin contents among the species were found. Even though low concentrations were detected, the levels of toxins that were present, especially in edible species, indicate the importance of these types of studies. Routine monitoring should be extended to comprise a wider number of vectors other than for bivalves of okadaic acid and its analogues.

    Five new species of recently extinct rails from two Macaronesian archipelagoes (Madeira and Azores) are described. All the species are smaller in size than their presumed ancestor, the European rail Rallus aquaticus. Two species inhabited the Madeira archipelago: (1) Rallus lowei n. sp., the stouter of the species described herein, was a flightless rail with a robust tarsometatarsus and reduced wings that lived on Madeira Island; (2) Rallus adolfocaesaris n. sp., a flightless and more gracile species than its Madeiran counterpart, inhabited Porto Santo. So far, six Azorean islands have been paleontologically explored, and the remains of fossil rails have been found on all of them. Here we formally describe the best-preserved remains from three islands (Pico, São Miguel and São Jorge): (1) Rallus montivagorum n. sp., a rail smaller than R. aquaticus with a somewhat reduced flying capability, inhabited Pico; (2) Rallus carvaoensis n. sp., a small flightless rail with short and stout legs and a bill apparently more curved than in R. aquaticus, was restricted to São Miguel; (3) Rallus minutus n. sp., a very small (approaching Atlantisia rogersi in size) flightless rail with a shortened robust tarsometatarsus, lived in São Jorge. We note also the presence of rail fossils on three other Azorean islands (Terceira, Graciosa and Santa Maria). In addition, we describe an extraordinarily complete fossil of an unnamed Rallus preserved in silica from the locality of Algar do Carvão on Terceira.

    The capacity of the Azores Archipelago to capture and retain incoming particles and organisms that are drifting with the oceanic currents was the main focus of this study. Using the Hybrid Coordinate Ocean Model coupled with the Connectivity Modeling System (an offline Lagrangian tool) a series of experiments were conducted to determine: i) the origin of the particles that reach the archipelago, ii) the capacity of each island sub-group to retain incoming particles and organisms, as well as the iii) oceanographic phenomena that lead to their transport and retention. The Gulf Stream (GS) and the westward propagating eddy corridors were identified as the main transport pathways affecting the Azores region. Eddy Kinetic Energy from altimetry data and Lyapunov exponent analysis suggest that eddies and filaments are the main delivery mechanisms. In the upper mixed layer, the GS and its associated eddies are a predominant regional oceanographic feature injecting particles from the north and west boundaries toward the Azores. The capacity to capture particles of each island sub-group was directly proportional to their size, while the retention time within the Azores region increased with depth, associated with the decrease in velocity of the intermediate water currents. This study opens new prospects to understand transport in the Mid-Atlantic (Azores) region and the islands' role in marine colonization, dispersal, fisheries recruitment and speciation.

    Full Text Available The Azores archipelago in the North Atlantic is an important area for biodiversity because it is rich in rare species and habitats, and almost undisturbed. Sanguinhal mire was originally a lake that evolved through paludification into a peat habitat. It is located inside Nature 2000 (European Union for Protection of Nature and Biodiversity, Council Directive 92/43/EEC of 21 May 1992 on the conservation of natural habitats and of wild fauna and flora, Habitat Directive Annex I(b habitat 7140 area of Santa Bárbara and Pico Alto Mountains on the island of Terceira, and it is a good example of a basin peatland type that was first discovered in 1998. This paper provides baseline information on its flora, vegetation communities, structure, surface hydrology and chemistry. Forty-one plant species including six Sphagnum species and ten endemic vascular plants have been recorded, and eight plant communities are distinguished. The maximum peat depth is 2.5 m. The mire receives flowing water from its margins, in addition to intercepted precipitation and fog. After precipitation, water drains through several placic rupture points. Both pH and water conductivity were measured, with some ecological tendencies observed. The conservation status of the mire is good, but it is subject to increasing pressure from cattle pasture and a walking trail that constrains natural surface water movement.O Arquipélago dos Açores no Atlântico Norte é uma área importante em biodiversidade, rica em espécies e habitats raros em estado selvagem.

    Each summer, the Center for Integrating Research and Learning (CIRL) at the National High Magnetic Field Laboratory (NHMFL) operates a Research Experiences for Teachers (RET) program. This six-week program provides stipends for teachers to work in the laboratories of NHMFL scientists. Faculty members of the Geochemistry Program at the NHMFL frequently host RET teachers to facilitate the broader dissemination of Geoscience knowledge among K-12 educators. During the summer of 2009, David d’Albany and Charles Carpenter, participated in the RET program for K-12 teachers at the NHMFL in Tallahassee, Florida. Mr. d’Albany is a Biology teacher at King IB High School in Tampa, Florida. Mr. Carpenter is a Physics teacher at Lawton Chiles High School in Tallahassee, Florida. Both teachers had the opportunity to analyze the elemental composition of a volcanic rock from the Azores Islands, in the North Atlantic. The Azores Islands represent a set of nine volcanic islands, near the active Azores Triple Junction, on the mid-Atlantic Ridge around 38°N, generally conceived as the products of a deep mantle plume. The analytical method used was Laser Ablation Inductively Coupled Plasma Mass Spectrometry (ICP-MS) using a New Wave UP193FX excimer laser ablation system coupled to a Thermo Element XR magnetic sector ICP-MS. This method allowed solid sampling of a large area of the basaltic matrix, and separately of the olivine (peridot) crystals within the matrix, from a lava sample from the island of Faial. Elemental data were obtained on a broader spectrum of elements (65 elements) than currently available in the geochemical literature for these islands. Chondrite-normalized rare earth element abundances for the sample provided a precise match with data for other lavas from the island of Faial from the GEOROC database. It should be noted that all 14 lanthanides, excluding Pm, were measured with ICP-MS, compared with about 8 elements determined by previous bulk rock techniques

    The Azores platform, where the Eurasian, Nubian and American plates meet, comprises nine volcanic islands extending to both sides of the Mid-Atlantic Ridge (MAR). East of the MAR, the plate boundary between Eurasian and Nubian plates is defined by the Terceira Rift, interpreted as an intra-oceanic spreading system where the Islands of S. Miguel, Terceira and Graciosa emerge as well and the submarine D.João de Castro Bank, separated by deep avolcanic zones [1, 2]. Submarine and subaerial lavas from the Terceira Rift are characterized by small-scale elemental and isotopic variations, and several distinct compositional end-members have been identified [2,3] supporting the concept of significant mantle source heterogeneity. A recent submarine eruption (1998-2001) occurred ~4-5 NM WNW of Terceira Island, at the Serreta Ridge where lava balloons were observed floating at the surface [4]. In 2008, an oceanographic cruise was conducted to the Serreta ridge to investigate the site of the 1998-2001 eruption, map the seafloor, identify vent location, and characterize possible products of eruption [5]. An ROV from the EMEPC (Task Group for the Extension of the Continental Shelf) was used in this survey providing high-definition video footage and fresh lava samples. Three survey ROV dives (D15, D16, D17) were made on the Serreta ridge. D15 and D17 dives were located on the southern wall of the crater, whereas D16 explored the central and northern areas of the crater floor. Sr-Nd-Pb isotope compositions of representative samples from the Serreta submarine ridge are presented for the first time. On the 208Pb/204Pb vs. 206Pb/204Pb diagram Serreta samples plot on a linear array with the remaining Terceira rift samples. However, these results show that Serreta submarine volcanics lay on the most depleted end of the Terceira Rift array. Radiogenic isotopes also show that samples from the central and northern wall of the crater are distinct from the younger southern wall sector

    In the Azores archipelago, a significant proportion of buildings are infested with the urban exotic drywood termite Cryptotermes brevis (Walker), causing major economical and patrimonial losses. This work aims to understand the potential spread of this termite species in the Azores and estimate the costs for both treatment and reconstruction of infested buildings in the entire archipelago. A maximum entropy niche modeling process was used to determine the potential occurrence of the species on each island. Different scenarios were built using independent global and regional incidence and environmental data. Both projections reveal the same pattern. Generally, the probability of occurrence is higher near the coast line, where, in Azores, the majority of the towns and villages are located. We also predict that the infestation has potential to spread to yet unaffected towns and islands. It is estimated that the cost of treating all currently infested buildings in the archipelago is Euro 51 million, while reconstruction of the same buildings would rise the costs to Euro 175 million. We predict that the absence of a control strategy will cause a further expansion of the pest to more localities in the Azores. An estimate to future scenarios implies higher costs, with treatment and rebuilding values rising up to eight times the current values.

    Full Text Available Miguel Fisac was a pithy person, sculpted from a single stone. There is no point in distinguishing parts where there were none, but it is worthwhile to attempt to analyze different points of view on the activity of a monolithic personality. Architects, designers, contractors, inventors, troublemakers and theologians among others could rightly claim him as one of their own. Given the exclusive attitudes adopted by most trades, however, they would be more likely to define him as “an outsider who did things”. At the age of nearly 93, in his last project, which he left in the design phase, he was planning to use the “construction system with precast members combining architecture and strength“ that he had patented years before in Spain and 21 other countries, the United States and Russia among them.Miguel Fisac era un personaje escueto, de una sola pieza, no cabe distinguir partes donde no las hay, pero si tratar de analizar desde distintos puntos de vista la actividad de una personalidad monolítica; arquitectos, diseñadores, constructores, inventores, polemistas y teólogos entre otros podrían con facilidad reivindicar su figura como uno de los suyos, aunque dado el afán de exclusividad que caracteriza a todo gremio, es más probable que lo calificaran como “alguien, de fuera, que ha hecho cosas”. Al filo de los 93 años, en su última obra, aún en proyecto, iba a emplear un “sistema de construcción mediante elementos prefabricados con funciones arquitectónicas y resistentes conjuntas” patentado por él hace años en España y en otros 21 países, entre ellos, Estados Unidos y Rusia.

    During 25-28 July 2003 the US Navy submarine NR-1 dove on the seamount D. Joao de Castro Bank, compiling reconnaissance sonar and visual data. Castro Bank sits along strike and between the eastern Azorian islands of Terceira and S. Miguel, occupying a seismically active region ˜60 km from each of these islands and apparently controlled by the same underlying tectonics as other islands found along the Azores' northern margin. Castro Bank's last recorded eruptions built a ˜1 km diameter ephemeral island in the 1720s. The bathimetry of the uppermost 40 m or so of the Bank is rather well known via single beam sonar, scuba diving and AUV surveys (IH, DOP/UA and ISR/IST, unpublished work). Our dives compiled data in concentric rings along contours, collecting side- and forward-looking sonar along an overall track length of ˜20 km, with the deepest ring approaching ˜200 m depth. To document key features we came near the sea floor and took videos in water with typical visibility of ˜10-15 m. This is the first progress report on our work, which found the edifice morphologically complex and irregular. We noted that the seamount was often covered by aerially extensive yellow-brown hyaloclastic tuffs that were presumably products of the 1720s eruption, but also cut by faults and fissures (with offsets of ten's of meters) exposing abundant areas of older edifice. The faults typically lacked sediment cover, and in one case a very fresh, sediment-free fault trended along the base of a steep cliff. This suggested the faults were much younger than the 1720 eruption, an observation in accord with intense seismicity recorded in this area. The faults provided exposures of older rocks, which included abundant breccia and lesser clearly identified pillows or thick lava flows. The NW quadrant contains two small, shallow, elliptical craters. These lie side-by-side and crosscut inferred 1720s-age tuffs. One crater held a lava lake, the body of which apparently withdrew or subsided

    The Southern Azores Seamount Chain (SASC) is a group of large seamounts located south of the Azores Plateau and east of the Mid-Atlantic Ridge (MAR) and part of the natural prolongation of the Azores land mass. The SASC, including the Great Meteor Seamount (aprox. 1000km south of São Miguel), is rooted on a flat, gently SE dipping Terrace, surrounded by steep scarps with almost 2000 m high. Only a few studies from the 70-80's discuss the geologic and/or geodynamic evolution of this region based on scarce bathymetry and geophysical data. Wendt et al. (1976) presented geochemical data and K-Ar ages on three basalt from the Great Meteor Seamount (<16Ma old), later analyzed for Sr-Nd-Pb isotopes by Geldmacher et al. (2006). Given the rarity of geochemical data, the origin of the seamounts and the regional evolution of this large area of the Atlantic, remains largely unknown. During the preparatory work of the PECSP, the EMEPC promoted three oceanographic campaigns to the SASC (2007, 2008 and 2009) with multidisciplinary teams. Within these cruises, more than 120 samples were dredged or collected with the Luso ROV (rated to 6000m depth) although less than 50 were suitable for major and trace elements analysis, for Sr-Nd-Pb-Hf isotopes and for K-Ar radiometric dating. Early studies relating the SASC with the New England Seamounts can be refuted by geophysical data and kinematic models presented by Gente et al. (2003) and, also by our new isotopic data, which shows that isotope ratios are clearly distinct from New England (Ribeiro et al., in prep). However, the analyzed SASC basalts display isotope ratios that overlap the Azores isotopic signature. Two new K-Ar ages (unspiked Cassignol-Gillot technique on fresh separated groundmass and/or plagioclase microlites) on the seamounts show coeval volcanism at Plato Seamount SE flank (33.4±0.5 Ma) an at Small Hyeres Seamount (31.7±0.5Ma). The SASC basalts erupted on the Terrace through an oceanic crust with 26Ma and 43Ma

  7. Benthic macroinvertebrate based indices for assessing the ecological status of freshwaters on oceanic islands

    Full Text Available Following the Water Framework Directive (2000/60/EC, macroinvertebrates are required biological elements for monitoring European aquatic ecosystems. Several efforts have been made towards establishing a biomonitoring programme for the Azores freshwater systems using benthic macroinvertebrates. However, little was previously known concerning Azorean freshwater macroinvertebrate fauna. Data from a major ongoing survey of macroinvertebrate freshwater fauna for two islands are presented and the use ofmacroinvertebrates as water quality indicators for the Azorean streams is evaluated. The upper, middle and lower reaches of streams longer than 10 km from São Miguel (10 and Santa Maria (1 were surveyed (a total of 33 samples. A total of 21 taxa were collected;Diptera, in particular chironomidae, were dominant; chironomids were collected from all sampling sites. The Azorean lotic fauna is characterized by low levels of abundance and the absence of macroinvertebrate groups commonly associated with continental systems.Traditional biotic indices, used to classify ecological quality, yielded poor to bad classifications despite little or no environmental impacts at the sampling sites. The paucityof macroinvertebrate fauna is probably due to the result of geological and physicochemical processes, the oceanic character of the islands, their volcanic origin, small size and geological youth and climate related factors such as seasonal peaks in rainfall. Considering these constraints, we demonstrate that watershed age plays a determinant role in shaping Azorean macroinvertebrate freshwater communities which can confound the water quality classification via the use of traditional biotic indices.

  12. Post-eruptive Submarine Terrace Development of Capelinhos, Azores

    Erosion of the coasts of volcanic islands by waves creates shallow banks, but how erosion proceeds with time to create them and how it relates to wave climate is unclear. In this study, historical and recent marine geophysical data collected around the Capelinhos promontory (western Faial Island, Azores) offer an unusual opportunity to characterize how a submarine terrace developed after the eruption. The promontory was formed in 1957/58 during a Surtseyan eruption that terminated with extensive lava forming new rocky coastal cliffs. Historical measurements of coastline position are supplemented here with coastlines measured from 2004 and 2014 Google Earth images in order to characterize coastline retreat rate and distance for lava- and tephra-dominated cliffs. Swath mapping sonars were used to characterize the submarine geometry of the resulting terrace (terrace edge position, gradient and morphology). Limited photographs are available from a SCUBA dive and drop-down camera deployments to ground truth the submarine geomorphology. The results reveal that coastal retreat rates have decreased rapidly with the time after the eruption, possibly explained by the evolving resistance to erosion of cliff base materials. Surprisingly, coastline retreat rate decreases with terrace width in a simple inverse power law with terrace width. We suspect this is only a fortuitous result as wave attenuation over the terrace will not obviously produce the variation, but nevertheless it shows how rapidly the retreat rate declines. Understanding the relationship between terrace widening shelf and coastal cliff retreat rate may be more widely interesting if they can be used to understand how islands evolve over time into abrasional banks and guyots.

  13. Evidence for recycled Archaean oceanic mantle lithosphere in the Azores plume.

    The compositional differences between mid-ocean-ridge and ocean-island basalts place important constraints on the form of mantle convection. Also, it is thought that the scale and nature of heterogeneities within plumes and the degree to which heterogeneous material endures within the mantle might be reflected in spatial variations of basalt composition observed at the Earth's surface. Here we report osmium isotope data on lavas from a transect across the Azores archipelago which vary in a symmetrical pattern across what is thought to be a mantle plume. Many of the lavas from the centre of the plume have lower 187Os/188Os ratios than most ocean-island basalts and some extend to subchondritic 187Os/188Os ratios-lower than any yet reported from ocean-island basalts. These low ratios require derivation from a depleted, harzburgitic mantle, consistent with the low-iron signature of the Azores plume. Rhenium-depletion model ages extend to 2.5 Gyr, and we infer that the osmium isotope signature is unlikely to be derived from Iberian subcontinental lithospheric mantle. Instead, we interpret the osmium isotope signature as having a deep origin and infer that it may be recycled, Archaean oceanic mantle lithosphere that has delaminated from its overlying oceanic crust. If correct, our data provide evidence for deep mantle subduction and storage of oceanic mantle lithosphere during the Archaean era.

    Outbreaks of pithomycotoxicosis (facial eczema), a hepatogenous photosensitisation caused by the mycotoxin sporidesmin, have affected ruminants in the Azores Islands of Portugal after warm, humid periods during late summer and autumn. Twenty-two outbreaks were recorded in cattle between 1999 and 2001, affecting 11.4 per cent of the animals in the affected herds, and in 2000 there was an outbreak in one sheep flock in which more than 20 per cent of the sheep died. The clinical signs included decreases in milk production, weight loss, photosensitisation and its sequelae, including death. The animals had high activities of gamma glutamyltransferase in their serum, and icterus and severe liver disease, including biliary hyperplasia and fibrosis, were found postmortem. The characteristic spores of the toxigenic saprophytic fungus Pithomyces chartarum were found on grass; all 381 isolates of the fungus were toxigenic for sporidesmin by elisa, and the results were confirmed by high-performance liquid chromatography analysis. Cattle from farms at greatest risk of pithomycotoxicosis were protected by supplementing their concentrate feed with zinc oxide, or using a slow-release intraruminal zinc bolus.

    1999-09-01

    A health hazard assessment of exposure to soil gases (carbon dioxide and radon) was undertaken in the village of Furnas, located in the caldera of an active volcano. A soil survey to map the area of soil gas flow was undertaken, gas emissions were monitored at fumaroles and in eight houses, and a preliminary radon survey of 23 houses in the main anomaly area was performed. Potential volcanic sources of toxic contamination of air, food, and water were also investigated, and ambient air quality was evaluated. About one-third (41 ha) of the houses were located in areas of elevated carbon dioxide soil degassing. Unventilated, confined spaces in some houses contained levels of carbon dioxide which could cause asphyxiation. Mean indoor radon levels exceeded UK and US action levels in the winter months. A tenfold increase in radon levels in one house over 2 h indicated that large and potentially lethal surges of carbon dioxide could occur without warning. Toxic exposures from the gaseous emissions and from contamination of soil and water were minimal, but sulphur dioxide levels were mildly elevated close to fumaroles. In contrast, evidence of dental fluorosis was manifested in the population of the nearby fishing village of Ribeira Quente where drinking water in the past had contained elevated levels of fluoride. The disaster potential of volcanic carbon dioxide in the area could also be associated with the hydrothermal system storing dissolved carbon dioxide beneath the village. Felt, or unfelt, seismic activity, or magma unrest, especially with a reawakening of explosive volcanic activity (30% probability in the next 100 years) could result in an increase in gas flow or even a gas burst from the hydrothermal system. A survey of all houses in Furnas is advised as structural measures to prevent the ingress of soil gases, including radon, were needed in some of the study houses. Evaluations of the human hazards of volcanic gases should be undertaken in all settlements in volcanic and hydrothermal areas associated with soil gas emissions.

    Full Text Available Since 1999, our knowledge of arthropods in native forests of the Azores has improved greatly. Under the BALA project (Biodiversity of Arthropods of Laurisilva of the Azores, an extensive standardised sampling protocol was employed in most of the native forest cover of the Archipelago. Additionally, in 2003 and 2004, more intensive sampling was carried out in several fragments, resulting in nearly a doubling of the number of samples collected. A total of 6,770 samples from 100 sites distributed amongst 18 fragments of seven islands have been collected, resulting in almost 140,000 specimens having been caught. Overall, 452 arthropod species belonging to Araneae, Opilionida, Pseudoscorpionida, Myriapoda and Insecta (excluding Diptera and Hymenoptera were recorded. Altogether, Coleoptera, Hemiptera, Araneae and Lepidoptera comprised the major proportion of the total diversity (84% and total abundance (78% found. Endemic species comprised almost half of the individuals sampled. Most of the taxonomic, colonization, and trophic groups analysed showed a significantly left unimodal distribution of species occurrences, with almost all islands, fragments or sites having exclusive species. Araneae was the only group to show a strong bimodal distribution. Only a third of the species was common to both the canopy and soil, the remaining being equally exclusive to each stratum. Canopy and soil strata showed a strongly distinct species composition, the composition being more similar within the same stratum regardless of the location, than within samples from both strata at the same location. Possible reasons for these findings are explored. The procedures applied in the sampling protocol are also discussed.

    2017-08-01

    Full Text Available Miguel de Unamuno, one of the most prominent intellectuals of Spain towards the end of the 19th century and first third of the 20th century, since his crisis in 1987 strived to warn of the limits to intellectualism. In his paper Intellectualism and Spirituality (March 1904, he reflected on the bodily, intellectual and spiritual dimensions of the human being, mindful of the First Letter of St. Paul to the Corinthians. He defined three types of people: the carnal (the downright uneducated, the intellectual (those who show logic and common sense and the spiritual (dreamers and poets. Without undermining intellectualism and facing the reductionism of any sign, as Pascal Unamuno highlighted the importance and significance of spirituality by being aware that it focuses on creating meaning and conquering the ideal, paving the way for a more fruitful life.

  10. Short-term variability of gamma radiation at the ARM Eastern North Atlantic (ENA) site (Azores)

    Barbosa, Susana; Miranda, Pedro; Azevedo, Eduardo

    2017-04-01

    Naturally-occurring radionuclides, and radon and its progeny in particular, can be used as a sensitive atmospheric tracer and an indicator of dynamic processes in the lower troposphere. Radiation from gamma-emitting radionuclides (including Rn-222 progeny) is being continuously monitored since May 2015 in the framework of an ARM campaign at the Eastern North Atlantic (ENA) facility located in the Graciosa island (Azores, 39N; 28W), a fixed site of the Atmospheric Radiation Measurement programme (ARM), established and supported by the Department of Energy (DOE) of the United States of America with the collaboration of the Government of the Autonomous Region of the Azores and University of the Azores. The resulting time series of 15-minute gamma ray counts radiation is characterized by occasional anomalies over a slowly-varying signal. Sharp peaks lasting typically 2-4 hours are coincident with heavy precipitation (> 10 mm/hour) and result from the scavenging effect of precipitation bringing radon progeny from the upper levels to the ground surface. However, the connection between gamma variability and precipitation is not straightforward as a result of the complex interplay of factors such as the precipitation intensity, the boundary layer height, the cloud's base height and thickness, or the air mass origin and atmospheric concentration of sub-micron aerosols, which influence the scavenging processes and therefore the concentration of radon progeny. Convective precipitation associated with cumuliform clouds forming under conditions of warming of the ground relative to the air does not produce enhancements in gamma radiation, likely as a result of the drop growing process being dominated by the fast accretion of liquid water, resulting in the reduction of the concentration of radionuclides by dilution. Events of convective precipitation further contribute to a reduction in gamma counts by inhibiting radon release from the soil surface and by attenuating gamma rays

    San Miguel volcano, also known as Chaparrastique, is one of many volcanoes along the volcanic arc in El Salvador. The volcano, located in the eastern part of the country, rises to an altitude of about 2130 meters and towers above the communities of San Miguel, El Transito, San Rafael Oriente, and San Jorge. In addition to the larger communities that surround the volcano, several smaller communities and coffee plantations are located on or around the flanks of the volcano, and the PanAmerican and coastal highways cross the lowermost northern and southern flanks of the volcano. The population density around San Miguel volcano coupled with the proximity of major transportation routes increases the risk that even small volcano-related events, like landslides or eruptions, may have significant impact on people and infrastructure. San Miguel volcano is one of the most active volcanoes in El Salvador; it has erupted at least 29 times since 1699. Historical eruptions of the volcano consisted mainly of relatively quiescent emplacement of lava flows or minor explosions that generated modest tephra falls (erupted fragments of microscopic ash to meter sized blocks that are dispersed into the atmosphere and fall to the ground). Little is known, however, about prehistoric eruptions of the volcano. Chemical analyses of prehistoric lava flows and thin tephra falls from San Miguel volcano indicate that the volcano is composed dominantly of basalt (rock having silica content

    The diagenetic history of calcareous fossils is required for their application as palaeoenvironmental indicators. In this study, cathodoluminescence-microscopy (CL microscopy) and back scatter electron image-energy dispersive X-ray spectroscopy (BSE-EDS microscopy) were applied to Pliocene rhodoliths from the Azores Archipelago (NE Atlantic) in order to gain additional insight regarding the trace element content distribution throughout the algae thalli, and to ascertain palaeoenvironmental interpretations. Two types of luminescence were obtained: (1) high and (2) low luminescence. Rhodoliths with high luminescence are related with high concentrations of Mn(2+) in seawater and low luminescence rhodoliths are related with low concentrations of Mn(2+) in seawater. When the rhodoliths were deposited at about 4.0-4.5 Ma, the shoreline configuration of Santa Maria Island was much different than today. The influence of volcanic activity due to the extrusion of lavas and associated products and/or the presence of active shallow-water hydrothermal vents, was reflected in the sea water chemistry, with penecontemporaneous palaeoshores of the island featuring a high sea water concentration of Mn(2+), which mirrored on the rhodolith Mn(2+) high concentration. By contrast, rhodoliths located about 2.8 and 2.9 km from the shore, in areas with low seawater Mn(2+) concentration, had low luminescence, reflecting the low Mn(2+) concentration in seawater. Rhodoliths chemical data and the geological history of the island proved to be congruent with the palaeogeographical reconstruction of Santa Maria Island at the time of the formation of the rhodoliths.

    Neves, Verónica; Nolf, Dirk; Clarke, Malcolm

    2012-12-01

    The diet of Cory's shearwater Calonectris diomedea in the Azores was studied in four islands of the archipelago over four breeding seasons, using stomach flushings from 959 birds. Fish were identified from flesh, otoliths and vertebrae and cephalopods from flesh and lower beaks. The frequency of occurrence of prey taxa, and the numerical frequency of fish and cephalopods, showed marked variations both spatially, across the breeding cycle and between years. Overall, cephalopods from 37 species representing 17 families and fish from 33 species representing 18 families were identified, representing over 70 prey species and trebling what was previously known. Histioteuthidae, Ommastrephidae and Cranchiidae were the only cephalopod families present every year and represented two thirds of the cephalopods' consumption by number. Blue jack mackerel Trachurus picturatus was the most abundant prey species present in 1998 and 2002 but was absent in 1999 and 2000, representing on average 57.2% of prey by number in the years it occurred. Apart from blue jack mackerel, most fish species were present in very low numbers with the exception of Cubiceps gracilis, Scomberesox saurus and Maurolicus muellerii. Diaphus adenomus, was recorded for the first time for the Azores archipelago.

  18. Volcano-tectonic framework of a linear volcanic ridge (Faial-Pico ridge, Azores Archipelago) assessed by paleomagnetic studies

    The morphology of volcanic oceanic islands results from the alternation between constructive and destructive episodes. In this study directional analyses obtained from paleomagnetic studies are used as a tool to achieve relative rotations related with destructive processes intra the Pico-Faial linear volcanic ridge (Azores archipelago; North Atlantic). A total of 45 lava flows and one dyke were sampled preferable along lava piles though to record volcano-tectonic movements. The respective paleomagnetic results are able to show important rotations within the two islands that resemble the onshore signature of this ridge. Paleomagnetic directions retrieved here mostly show elliptical distribution of ChRM's sub-perpendicular to volcanic ridge. Such distribution agrees with the development of listric faults plunging towards the axis of the volcanic ridge at Faial Island and towards offshore at the Topo complex of Pico Island. In Faial Island, the "collapse" related to the magma chamber decompression was accommodated by brittle deformation with listric faults plunging toward the core of the formed graben. On Pico Island, this collapse was probably of less importance and simply accommodated by a local tilting. Listric faults then should have been developed, in the opposite direction (compared to Faial Island case) relatively to the collapsed area, to compensate a relative local uplift. Accordingly paleomagnetic studies appear as key data to retrieve intra-islands deformations due to the volcano-tectonic balance responsible for the construction and destruction of such unstable buildings. This important tool to address georisks and natural hazards remains poorly explored and need to be strongly developed. The author wish to acknowledge MEGAHAZARDS (PTDC/CTE-GIX/108149/2008) and REGENA (PTDC/GEO-FIQ/3648/2012) projects for its major contribution without which this work wouldn't be possible.

    The most recent submarine eruption observed offshore the Azores archipelago occurred between 1998 and 2001 along the submarine Serreta ridge (SSR), 4-5 nautical miles WNW of Terceira Island. This submarine eruption delivered abundant basaltic lava balloons floating at the sea surface and significantly changed the bathymetry around the eruption area. Our work combines bathymetry, volcanic facies cartography, petrography, rock magnetism and geochemistry in order to (1) track the possible vent source at seabed, (2) better constrain the Azores magma source(s) sampled through the Serreta submarine volcanic event, and (3) interpret the data within the small-scale mantle source heterogeneity framework that has been demonstrated for the Azores archipelago. Lava balloons sampled at sea surface display a radiogenic signature, which is also correlated with relatively primitive (low) 4He/3He isotopic ratios. Conversely, SSR lavas are characterized by significantly lower radiogenic 87Sr/86Sr, 206Pb/204Pb and 208Pb/204Pb ratios than the lava balloons and the onshore lavas from the Terceira Island. SSR lavas are primitive, but incompatible trace-enriched. Apparent decoupling between the enriched incompatible trace element abundances and depleted radiogenic isotope ratios is best explained by binary mixing of a depleted MORB source and a HIMU­type component into magma batches that evolved by similar shallower processes in their travel to the surface. The collected data suggest that the freshest samples collected in the SSR may correspond to volcanic products of an unnoticed and more recent eruption than the 1998-2001 episode.

    The valley of San Miguel, located in the state of Baja California, Mexico, is an important region because of the wine industry. It is therefore important to know groundwater characteristics. Two aquifers can be recognized in the San Miguel basin, first one is in fractured granitic rocks (in the upper part of the basin, called UB) and other is free-type in detritc sediments (in the lower part of the basin, close to the sea, called LB). The water temperature ranges between 25°C y 11°C without significant variations along the year. The conductivity increases with the water temperature and decreases in February when the temperature is lower. The pH of the waters in UB is between 8.5 and 6.5 but in the LB is in the range of 6.8 to 7.3. Our data show that Na, Mg, and HCO3- concentrations decrease during the rainy season due to ion exchange. According to the Stiff diagrams the waters of the LB are classified as sodium chloride. In the UB the water classification includes calcium and magnesium bicarbonate, magnesium chloride, and few calcium chloride and sodium chloride. The saturation indexes of the waters suggest that the mineral phases which can be present are: K-feldspar, gibbsite, albite, quartz, calcite, aragonite, gypsum, and magnesite. Because of SI>0 then the first four phases can precipitate but the SI of magnesite and gypsum is negative thus the can be dissolved. Finally, calcite and aragonite are in equilibrium due to they are close to zero. Our results suggest that the aquifers of the San Miguel basin do not show evidence of saline intrusion.

    Miguel Torga (Sao Martinho de Anta 1907 - Coimbra 1995) was one of the most important portuguese writers of the twentieth century. There is such identity between his medical and literary activity that he used to say that "his own hand not only writes but also prescribes". Reading his work, mainly autobiographical, allows us to analyze their vision of medicine, the patient physician relationship and how a doctor lives his own disease. In the first case medicine constitute an essential tool to help nature and, therefore, an instrument that makes hope possible. In the second case indicates that in the patient physician relationship are present sadness, stress, anxiety and a supreme exercise of the human condition which is the anamnesis when the patients open their intimity to the doctor. In the third case Torga's work illustrates how a physician can live his own illness as an advantage, as a judicial sentence or as a possibility. Approaching to the medicine under perspective of Miguel Torga, doctor and writer, will help us to understand medicine in a more human context in which the life of the doctor is not stranger to their patients, or to the nature and the concrete world that both share.

    This article reports the necropsy of a specimen of striped dolphinStenella coeruleoalba found stranded in the north coast of Terceira Island, Azores, Portugal. Here, the importance of standard protocols in post-mortem examinations and the need to adequately proceed were discussed. Stranded marine mammals are valuable specimens for several studies of pathology and other veterinary medical aspects. Although the causa mortis was not determined, the full access to stranded specimens was crucial, not only for pathology studies but also for a proper training to veterinary medicine students whenever possible.

    The majority of our knowledge on marine tapeworms (cestodes) is limited to taxa that are relatively easy to obtain (i.e., those that parasitize shallower-water species). The invitation to participate in a deep-water research survey off the Condor seamount in the Azores offered the opportunity to gain information regarding parasites of the less often studied sharks of the mesopelagic and bathypelagic zone. All tapeworms (Platyhelminthes: Cestoda) found parasitizing the spiral intestine of squaliform shark species (Elasmobranchii: Squaliformes) encountered as part of this survey, as well as some additional Azorean sampling from previous years obtained from local fishermen are reported. In total, 112 shark specimens of 12 species of squaliform sharks representing 4 different families from depths ranging between 400 and 1290 m were examined. Cestodes were found in the spiral intestines from 11 of the 12 squaliform species examined: Deania calcea, D. cf. profundorum, D. profundorum, Etmopterus princeps, E. pusillus, E. spinax, Centroscyllium fabricii, Centroscymnus coelolepis, C. cryptacanthus, C. crepidater, and Dalatias licha. No cestodes were found in the spiral intestines of Centrophorus squamosus. Light microscopy and scanning electron microscopy revealed several potentially novel trypanorhynch and biloculated tetraphyllidean species. Aporhynchid and gilquiniid trypanorhynchs dominated the adult cestode fauna of Etmopterus and Deania host species, respectively, while larval phyllobothriids were found across several host genera, including, Deania, Centroscyllium, and Centroscymnus. These results corroborate previous findings that deep-water cestode faunas are relatively depauperate and consist primarily of trypanorhynchs of the families Gilquiniidae and Aporhynchidae and larval tetraphyllideans. A subset of specimens of most cestode species was preserved in ethanol for future molecular analysis to allow more definitive determinations of the identification of the

    New collections of cestodes from the spiral intestines of the lanternsharks Etmopterus spinax and Etmopterus pusillus off the island of Faial, in the Azores, Atlantic Ocean, have yielded 2 new species of trypanorhynchs belonging to Aporhynchus. Both species share the distinctive lack of all elements of the rhyncheal system that are characteristic of this genus. The identity of Aporhynchus norvegicus is clarified to allow it to be distinguished from A. menezesi n. sp., which also parasitizes E. spinax. This new species differs conspicuously from its congeners in that its mature and gravid proglottids are wider than long, rather than longer than wide, and also in its lack of spinitriches on the scolex. Aporhynchus pickeringae n. sp., the new species from E. pusillus , differs from all of its congeners except A. norvegicus in that it is a relatively delicate worm with relatively fewer testes. It also possesses fewer proglottids and a wider pedunculus scolecis than does A. norvegicus. Sections through the scolex of A. menezesi n. sp. support use of the term bothriate, rather than difossate, in reference to the scolex configuration of some trypanorhynchs. A key to the 4 species of Aporhynchus is provided.

    The location of the Azores Archipelago in the North Atlantic makes this group of islands an excellent setting to study the long-term behavior of large oceanic and atmospheric climate dynamic patterns, such as the Atlantic Multidecadal Oscillation (AMO) and the North Atlantic Oscillation (NAO). Here, we present the impacts of these patterns on Lake Empadadas (Azores Archipelago) from the Medieval Climate Anomaly (MCA) - Little Ice Age (LIA) transition to the present based on sedimentological, geochemical and biological characterizations of the sedimentary record. Multivariate analyses of a number of proxies including X-ray fluorescence (XRF), X-ray diffraction (XRD), total organic and inorganic carbon (TOC and TIC) and diatom life forms abundance reveal that the sedimentary infill evolution has been controlled by (i) fluctuations in the lake level and (ii) variations in organic matter accumulation. Both processes are governed by climate variability and modulated by anthropogenic activities associated with changes on the lake catchment. Changes in these two sedimentary processes have been used to infer five stages: (i) the MCA-LIA transition (ca. 1350-1450 CE) was characterized by a predominantly positive AMO phase, which led to intermediate lake levels and high organic matter concentration; (ii) the first half of the LIA (ca. 1450-1600 CE) was characterized by predominant lowstand conditions and intermediate organic matter deposition mainly related to negative AMO phases; (iii) the second half of the LIA (ca. 1600-1850 CE) was characterized by negative AMO and NAO phases, implying intermediate lake levels and high organic matter deposition; (iv) the Industrial era (ca. 1850-1980 CE) was characterized by the lowest lake level and organic matter accumulation associated with negative AMO phases; and (v) the period spanning between 1980 CE and the present reveals the highest lake levels and low organic matter deposition, being associated with very positive AMO

    Marine stratocumulus clouds are low, persistent, liquid phase clouds that cover large areas and play a significant role in moderating the climate by reflecting large quantities of incoming solar radiation. The deficiencies in simulating these clouds in global climate models are widely recognized. Much of the uncertainty arises from sub-grid scale variability in the cloud albedo that is not accurately parameterized in climate models. The Clouds, Aerosol and Precipitation in the Marine Boundary Layer (CAP–MBL) observational campaign and the ongoing ARM site measurements on Graciosa Island in the Azores aim to sample the Northeast Atlantic low cloud regime. These data represent, the longest continuous research quality cloud radar/lidar/radiometer/aerosol data set of open-ocean shallow marine clouds in existence. Data coverage from CAP–MBL and the series of cruises to the southeast Pacific culminating in VOCALS will both be of sufficient length to contrast the two low cloud regimes and explore the joint variability of clouds in response to several environmental factors implicated in cloudiness transitions. Our research seeks to better understand cloud system processes in an underexplored but climatologically important maritime region. Our primary goal is an improved physical understanding of low marine clouds on temporal scales of hours to days. It is well understood that aerosols, synoptic-scale forcing, surface fluxes, mesoscale dynamics, and cloud microphysics all play a role in cloudiness transitions. However, the relative importance of each mechanism as a function of different environmental conditions is unknown. To better understand cloud forcing and response, we are documenting the joint variability of observed environmental factors and associated cloud characteristics. In order to narrow the realm of likely parameter ranges, we assess the relative importance of parameter conditions based primarily on two criteria: how often the condition occurs (frequency

    Measurements of nonmethane hydrocarbons (NMHC) at the Pico Mountain observatory at 2225 m asl on Pico Island, Azores, Portugal, from August 2004 to August 2005 (in part overlapping with the field campaign of the International Consortium on Atmospheric Research on Transport and Transformation study) were used to investigate NMHC sources and seasonal oxidation chemistry in the central North Atlantic region. Levels of anthropogenic NMHC were characteristic of the marine free troposphere. Their concentrations were low compared to continental sites at higher northern latitudes, but higher than data reported from a similarly located Pacific mountain site at Mauna Loa Observatory, Hawaii. These higher NMHC levels are indicative of a greater influence of the adjacent continents on air composition at Pico. Substantially enhanced NMHC concentrations during the summers of 2004 and 2005 were attributed to long-range transport of biomass burning plumes originating from fires in northern Canada, Alaska, and Siberia. This finding exemplifies the continuing impact of biomass burning plumes on atmospheric composition and chemistry many days downwind of these emission sources. Seasonal cycles with lower NMHC concentrations and lower ratios of more reactive to less reactive NMHC during summer reflect the higher degree of photochemical processing occurring during transport. The NMHC concentrations indicate no significant role of chlorine atom oxidation on NMHC. Ozone above 35 ppbv was measured at Pico Mountain throughout all seasons. Enhanced ozone levels were observed in air that had relatively "fresh" photochemical signatures (e.g., ln [propane]/[ethane] > -2.5). During spring-summer air that was more processed ("older" air with ln [propane]/[ethane] < -2.5) on average had lower ozone levels (down to <20 ppbv). This relationship indicates that conditions in the lower free troposphere over the mid-North Atlantic during the spring and summer lead to net photochemical ozone destruction

    Pico Mountain (2325m asl) is a dormant volcano in the archipelago of the Azores1500 km west of Lisbon, Portugal in the North Atlantic. It differs from typical mountain ranges such as the Alps or the Rockies, which are large and present a complex orography. Pico Mountain has a simple cone-like structure with only one main peak and is thousands of kilometers away from any other significant mountain range. In summer months, it is typical for air masses to move around the mountain rather than traveling up its face. This implies that often the peak of the mountain lies above the marine boundary layer in the free troposphere, while the lower part of the mountain is affected by marine clouds and marine air-masses. An atmospheric monitoring station, the Pico Mountain Observatory was established in 2001 in the summit caldera of the volcano at 2225m above sea level. The observatory is far from large populations or pollution sources, which makes the station ideal to study atmospheric gases and aerosols transported over long-ranges in the free troposphere. The station is reachable only by foot following a steep and strenuous hiking trail. In the summer of 2013 we began to collect vertical profiles of aerosol by carrying an instrumented backpack up to the summit of the mountain, with the goal of studying the vertical structure of atmospheric aerosols from the marine boundary layer to the free troposphere. The backpack was carried from the base of trail at 1200m asl. The backpack was equipped with the following instruments: 1. Nephelometer to measure light scattering from aerosol 2. 2-size optical particle counter (300-500 nm) 3. Portable micro-aethalometer to measure absorbing aerosols 4. SEM/TEM sampler to collect particles for off-line electron microscopy analysis 5. Battery powered data logger to measure relative humidity, temperature and pressure 6. GPS tracking device We provide a preliminary analysis of data collected in 2013 to gain insight on the vertical distribution

    The genetic relationships between 10 rabbit hemorrhagic disease strains collected in Portugal between 2006 and 2013, originated in the mainland and Azorean islands, were investigated based on the vp60 gene variability. A genetic diversity ranging from 2% to 13% was determined among the 10-vp60 complete sequences revealing a significant level of genetic heterogeneity between same strains. Phylogenetic Bayesian analysis showed that the Portuguese RHDV strains fell within different genogroups, namely G1, G5 and G6. Interestingly, all strains obtained from Azores, where RHDV was first detected in 1988, belong to G5 genogroup. G5 strains, that were not identified in the continent so far, seem to be the dominant group in these Atlantic islands. G1-related strains belonging to the Iberian group 3 (n=3) and G6 (RHDVa) strains (n=2) were identified among the samples originated in mainland which were collected between 2006 and 2008. Although the presence of G1 and G6 in Portugal had been shown before, our data refines the time of circulation of these strains until at least 2008. In summary, this study revises the epidemiological information of RHDV in Portugal since it reports for the first time the presence of G5 strains in Azores and demonstrates the circulation of G1 and G6 strains in mainland Portugal until the late 2000s.

    The prevalence of antibiotic resistance and the implicated mechanisms of resistance were evaluated in Enterococcus spp. and Escherichia coli, isolated from a total of 250 faecal samples of echinoderms collected from Azorean waters (Portugal). A total of 144 enterococci (120 Enterococcus faecium, 14 E. hirae, 8 E. faecalis, 2 E. gallinarum) and 10 E. coli were recovered. High percentages of resistance in enterococci were found for erythromycin, ampicillin, tetracyclin and ciprofloxacin. The erm(A) or erm(B), tet(M) and/or tet(L), vat(D), aac(6')-aph(2″) and aph(3')-IIIa genes were found in isolates resistant to erythromycin, tetracycline, quinupristin/dalfopristin, high-level gentamicin and high-level kanamycin, respectively. Resistance in E. coli isolates was detected for streptomycin, amikacin, tetracycline and tobramycin. The aadA gene was found in streptomycin-resistant isolates and tet(A)+tet(B) genes in tetracycline-resistant isolates. The data recovered are essential to improve knowledge about the dissemination of resistant strains through marine ecosystems and the possible implications involved in transferring these resistances either to other animals or to humans.

During the process of the democratic reorganization of the autocratic-bourgeois State, Reale was a legal counselor to João Figueiredo. In that capacity, he fought for a conservative political opening to be abided and understood by the people as a “gift.” This proximity created numerous issues because if Reale could not deny his old commitments, he could not likewise publicly admit his defense of the regime. Seeking to secure his position as an intellectual, Reale took several coordinated actions, the most important of which was to publish his memoirs.

    The Furnas volcanic complex is located in the eastern part of the São Miguel Island and comprises a 5 km × 8 km summit depression filled by two nested calderas with several craters and a lake. Present-day volcanic activity of Furnas volcano is mostly located in the northern part of the caldera, within the Furnas village and north to Furnas Lake, where hydrothermal manifestations are mainly fumarolic fields, steam vents, thermal springs, and intense soil diffuse degassing. Considering the Furnas volcano as a whole, the total integrated CO2 efflux is extremely high, with a total amount of CO2 close to 1000 ton per day (Viveiros et al., 2009). We present the first results of an electrical resistivity tomography (ERT), combined with audio-magneto-telluric (AMT) measurements aligned along two profiles inside the caldera. The purpose of this survey is to delimit the extent, the geometry, and the depth of the hydrothermal system and to correlate the deep resistivity structure with high resolution cartography of diffuse CO2 flux (Viveiros et al, 2015). The ERT and AMT methods are complementary in terms of resolution and penetration depth: ERT can image the structural details of shallow hydrothermal system (down to 100 m in our study) while AMT can image at lower resolution deeper structures at the roots of a volcano (down to 4 km in our study). Our first independent 2D inversions of the ERT-AMT data show a good agreement between the surficial and deeper features. Below the main fumarole area we observe a low resistivity body (less than 1 Ohmm) which corresponds well to the high CO2 flux at the surface and is associated with an extended conductive body at larger depth. These results strongly suggest the presence of hydrothermal waters at depth or/and the presence of altered clay-rich material. On a larger scale however, the geometry of the conducting zones differs slightly from what was expected from earlier surface studies, and may not be directly related to fault zones

    The COPERNICUS EMS Risk & Recovery Mapping (RRM) activity offers services to support efficient design and implementation of mitigation measures and recovery planning based on EO data exploitation. The Azores Archipelagos case was realized in the context of the FWC 259811 Copernicus EMS RRM, and provides potential impact information for a number of natural disasters. The analysis identified population and assets at risk (infrastructures and environment). The risk assessment was based on hazard and vulnerability of structural elements, road network characteristics, etc. Integration of different hazards and risks was accounted in establishing the necessary first response/ first aid infrastructure. EO data (Pleiades and WV-2), were used to establish a detailed background information, common for the assessment of the whole of the risks. A qualitative Flood hazard level was established, through a "Flood Susceptibility Index" that accounts for upstream drainage area and local slope along the drainage network (Manfreda et al. 2014). Indicators, representing different vulnerability typologies, were accounted for. The risk was established through intersecting hazard and vulnerability (risk- specific lookup table). Probabilistic seismic hazards maps (PGA) were obtained by applying the Cornell (1968) methodology as implemented in CRISIS2007 (Ordaz et al. 2007). The approach relied on the identification of potential sources, the assessment of earthquake recurrence and magnitude distribution, the selection of ground motion model, and the mathematical model to calculate seismic hazard. Lava eruption areas and a volcanic activity related coefficient were established through available historical data. Lava flow paths and their convergence were estimated through applying a cellular, automata based, Lava Flow Hazard numerical model (Gestur Leó Gislason, 2013).

    Oceanographic cruises have been conducted on the Condor seamount (SW Faial Island, Azores archipelago, NE Atlantic) since 2009 to collect in situ data and understand potential seamount effects on local biodiversity. Satellite data have been concurrently collected to infer the space-time upper-ocean optical property variability and the associated physical processes. The main limitation of this analysis is the persistent and significant cloud coverage above the region that, especially in some seasons, can significantly hinder satellite data availability. This study was meant to test the robust satellite technique (RST) over the Condor seamount, assess its capability to estimate multiyear trends and identify space-time anomalies. To this aim, 11-year MODIS/AQUA level 2-derived chlorophyll-a (chl-a) data were used. Results achieved for October 2010 show, within a large-scale analysis, the presence of well-defined areas of near-surface chl-a anomalies, highlighting the occurrence of a trapping effect due to flow-topography interaction processes. Regarding the Condor area, the chl-a anomalies detected along the eastern side of the seamount were linked to a strong vertical mixing that provided sufficient inorganic nutrients requested for productivity. The achieved results, whose accuracy was also tested through a comparison with in situ data, are consistent with those independently obtained by other authors who described the phytoplankton variability around the Condor seamount. This study shows the high potential of the RST approach to assess the chl-a variability in the space-time domain in oligotrophic regions such as the Azores, allowing the identification of the most important areas to be preserved and/or managed.

  20. Mantle Plume Upwelling Rates: Evidence from U-Series in Young Ocean Island Basalts

    U-series disequilibria measured in recent lavas at intraplate volcanoes provide a powerful probe to examine the validity of the plume model. U-Th and U-Pa fractionation produced during melting is a function of the melting rate. In turn, this parameter should scale with mantle upwelling velocities. Simply stated, a larger melting rate (larger mantle upwelling velocity) yields smaller Th and Pa excess relative to their parent nuclides. A number of observations supports this approach: (1) there is a negative correlation between 230Th excess and buoyancy fluxes (2) based on new measurements of 231Pa in the Azores, Iceland and the Galapagos and literature data, we show here that there is also a well defined correlation between 231Pa excess and buoyancy flux (3) For Hawaii, Iceland and the Azores, 230Th excess (or 231Pa excess) increases as a function of the distance from the centre of the `hotspot'. These observations suggests that `hotspot' buoyancy fluxes are associated with a greater melt production per unit of time and that the centre of `hotspot' corresponds to a faster mantle upwelling velocity than its periphery. This is therefore in strong support of a model where ocean islands are associated with faster upwelling at depth. However, there is in fact not a simple relationship between melt productivity and upwelling velocities. Notably, the presence of volatiles, of mafic lithologies or of variably enriched peridotitic source could all affect melting rate and hence U-Th-Pa fractionation. We have considered these issues in great detail using a large data base for the Azores islands. While there are clear variations in mantle source composition, they cannot explain the observations of increasing 231Pa/235U ratio with distance from the centre of the Azores hotspot . If we take into account the effect of water in the source of the Azores, it clearly affects the scaling between U-series fractionation and upwelling velocity but not the overall conclusions.

    Two species of stick insects are currently known to be present in the Macaronesian archipelagos: Clonopsis gallica (Charpentier) (Phasmatodea: Bacillidae) on the Canary Islands and in the Azores and Carausius morosus (Sinéty) (Phasmatidae) in the Azores. Here, we provide the first reliable records of the presence and distribution of C. gallica and C. morosus on Madeira Island. Egg and adult stages are briefly described along with some notes on the life history of these species in captivity. Data on islandwide distribution are based on specimens donated by the public in response to an article published in a daily newspaper. This method of data collection raised great popular interest in stick insects. The role of newspapers as a means of communicating awareness in biodiversity issues is discussed.

    Full Text Available In this article it is analyzed the role of the “Sustainable Development Multidisciplinary Committee of San Miguel Almaya” created in this community with an otomi background in the State of Mexico, with the purpose to continue with the touristic acts supported in 2006 by the Federal and State Secretaries of Tourism. All with the aim to get benefit from its potential, centered on a lagoon and an extinct volcano. The Committee was created in 2010 because an Eco Tourist Park wanted to be constructed; Even though two stages of the eco tourist park were constructed, it was not concluded; in order to give it continuity, the local authorities decided to negotiate resources. The purpose of the present document is to analyze through the Public Policy Networks the role its members played at the moment of taking decisions to determine if they created the necessary conditions to promote the tourist and the sustainability of the community. The study was based on the methodology of Cruz (2008 and Zabaleta (2006 which identifies the objectives, interests, resources, capabilities, limitations and attributions, between the elements that have an influence on establishing links; in this case, among the actors of the network formed inside the committee. The information was obtained from an empiric and documental investigation that included reunions with the local authorities. One of the most important results is that, the decisions taken within the committee and the exclusion of some of the actors stopped the sustainable development due to a lack of negotiation between its members and differences in their objectives and interests, resulting in a lack of compromise and cooperation to solve the normative, economic, ecologic and cultural problems of the community that could put into risk the touristic potential of the zone.

    Full Text Available El abordaje imaginario a la obra de Azorín nos incita a creer en un núcleo emocional constante, anterior a sus textos, e implicado en el proceso creador. Sobre esta base analizamos una de las obras más queridas por el propio Azorín: Al margen de los clásicos. De ella extraemos las imágenes y tendencias afectivas más relevantes en las que se manifiesta un contenido profundo acorde con la universalidad imaginaria en sus distintos regímenes de la imagen, y con la singularidad afectiva de la sensibilidad creadora. El paso del tiempo y la muerte constituyen el sentimiento vertebrador de un imaginario que pretende contrarrestar los efectos negativos de dicho sentimiento y rescatar los aspectos más puros y auténticos del espíritu humano, individual y colectivo. Al margen de los clásicos confirma la unidad afectiva e imaginaria que precede y cohesiona los distintos escritos de Azorín.

    Rabbit hemorrhagic disease is caused by a calicivirus, rabbit hemorrhagic disease virus (RHDV), which is responsible for high mortality in domestic and wild European rabbits (Oryctolagus cuniculus). RHDV strains were sequenced from wild European rabbits (Oryctolagus cuniculus algirus) collected in the Azorean island of Pico, Portugal. Phylogenetic analyses showed that the Pico RHDV strains diverge from all of the others described so far, but cluster with the genogroups 1-5 (G1-G5). The genetic distance between the Pico RHDV sequences and each G1, G2 and G3-G5 genogroup (~0.08) is compatible with an RHDV introduction at least 17 years ago. Our results show that in Pico, RHDV is the outcome of an independent evolution from the original RHDV strain that appeared in its European rabbit population. These are the first sequences of RHDV obtained in the subspecies O. c. algirus, outside of its original region, the Iberian Peninsula. Furthermore, we discuss the risk of rabbit translocations from the Azores to the Iberian Peninsula, where the rabbit wild populations are suffering high mortalities.

    The location of Azores turns it into an ideal platform for tracking the long-range transport of air masses from surrounding continents over the North Atlantic Ocean. Aerosol samples (PM{sub 10}) have been collected using an aethalometer located at PICO-NARE observatory, in Pico island, from 15 July 2001 to 18 April 2004. The instrument is at an altitude of 2225 m above mean sea level (AMSL), and sampled for 24 h in most cases, and for a few periods continuously. The data herein refer to daily collections of PM{sub 10} in the period July 2001-July 2002. Samples were assessed through instrumental neutron activation analysis, k{sub 0}-variant (k{sub 0}-INAA). The lanthanoids and actinoids with concentrations above detection limits and above blank backgrounds were La, Sm, Lu, and Th, U, respectively. Back-trajectory results by the HYSPLIT model have shown that the highest values of La are of African origin, likely related to Saharan-dust episodes, while U comes mainly from northern Europe and North-Central America, down to the Caribbean. Every element presents the same enrichment-factor pattern concerning its annual, summer and winter averages. As for lanthanoids, La and Sm are not enriched relatively to soil while Lu is (actinoids are enriched as well), which indicates preferential enrichment of heavy rare earths compared to the light ones.

    Oceanographic research in the Azores has only started 15 years ago. Nevertheless, it has been possible to evolve from the typical "research cruise approach" to a more versatile and integrated approach, that has proofed to be further rewarding and adequate for the size and resources of the group. The Azorean Oceanographers have participated and conducted several research cruises since 1990, and anticipating the importance of correlating in situ data with satellite data has lead us to plan the last of these, so that there was a coincidence of transects, moorings and satellite ground tracks. On the other hand, the group has invested in data processing and merging hydrological historical data with the results from the above mentioned oceanographic cruises, creating a hydrological database for the whole Atlantic Ocean. Also, through the application of a novel methodology and approach, the group has contributed to a new vision of the currents systems in the South Atlantic Ocean, namely with the newly found St. Helena Current, the congener of the Azores Current. As a result of this continued shift in methodology, the group is now using an integrated approach where field data, model output and processed altimeter data are merged to produce operational oceanography products, such as sea state charts and daily oceanic current charts.

    Jiménez-Munt, Ivone; Bird, Peter; Fernàndez, Manel

    We applied the thin-shell neotectonic modeling method to study the neotectonics of the Africa/Eurasia plate boundary in the Azores-Gibraltar region. The plate boundary consists of a simple fault system running from Azores to the Gorringe Bank where it branches along the Betics and Rift-Tell thrust fronts. Major faults in west Iberia and NW Africa have also been incorporated. Results are compared with seismic strain rates, fault slip rates and stress orientations. The best estimate for the fault friction coefficient is 0.1-0.15 meaning that the plate-boundary is only about 1/4 as strong as the adjacent lithosphere. The largest fault slip rates (>1.5 mm/yr) are obtained along the Gloria fault (strike-slip), and the Betic (transpressive) and Rif-Tell (compressive) thrust systems. Whereas tectonic activity in the Atlas region is comparable to that obtained along the plate boundary, the fault slip rates in the west Iberia fault systems are one order of magnitude less.

  9. MODELLING THE POTENTIAL DISTRIBUTION AND RICHNESS OF CETACEANS IN THE AZORES FROM FISHERIES OBSERVER PROGRAM DATA

    Full Text Available Marine spatial planning and ecological research call for high-resolution species distribution data. However, those data are still not available for most marine large vertebrates. The dynamic nature of oceanographic processes and the wide-ranging behavior of many marine vertebrates create further difficulties, as distribution data must incorporate both the spatial and temporal dimensions. Cetaceans play an essential role in structuring and maintaining marine ecosystems and face increasing threats from human activities. The Azores holds a high diversity of cetaceans but the information about spatial and temporal patterns of distribution for this marine megafauna group in the region is still very limited. To tackle this issue, we created monthly predictive cetacean distribution maps for spring and summer months, using data collected by the Azores Fisheries Observer Programme between 2004 and 2009. We then combined the individual predictive maps to obtain species richness maps for the same period. Our results reflect a great heterogeneity in distribution among species and within species among different months. This heterogeneity reflects a contrasting influence of oceanographic processes on the distribution of cetacean species. However, some persistent areas of increased species richness could also be identified from our results. We argue that policies aimed at effectively protecting cetaceans and their habitats must include the principle of dynamic ocean management coupled with other area-based management such as marine spatial planning.

    Marine boundary layer (MBL) cloud properties derived from the NASA Clouds and the Earth's Radiant Energy System (CERES) project using Terra and Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) data are compared with observations taken at the Department of Energy Atmospheric Radiation Measurement (ARM) Mobile Facility at the Azores (AMF-Azores) site from June 2009 through December 2010. Cloud properties derived from ARM ground-based observations were averaged over a 1 h interval centered at the satellite overpass time, while the CERES-MODIS (CM) results were averaged within a 30 km × 30 km grid box centered over the Azores site. A total of 63 daytime and 92 nighttime single-layered overcast MBL cloud cases were selected from 19 months of ARM radar-lidar and satellite observations. The CM cloud top/base heights (Htop/Hbase) were determined from cloud top/base temperatures (Ttop/Tbase) using a regional boundary layer lapse rate method. For daytime comparisons, the CM-derived Htop (Hbase), on average, is 0.063 km (0.068 km) higher (lower) than its ARM radar-lidar-observed counterpart, and the CM-derived Ttop and Tbase are 0.9 K less and 2.5 K greater than the surface values with high correlations (R2 = 0.82 and 0.84, respectively). In general, the cloud top comparisons agree better than the cloud base comparisons, because the CM cloud base temperatures and heights are secondary products determined from cloud top temperatures and heights. No significant day-night difference was found in the analyses. The comparisons of MBL cloud microphysical properties reveal that when averaged over a 30 km × 30 km area, the CM-retrieved cloud droplet effective radius (re) at 3.7 µm is 1.3 µm larger than that from the ARM retrievals (12.8 µm), while the CM-retrieved cloud liquid water path (LWP) is 13.5 gm-2 less than its ARM counterpart (114.2 gm-2) due to its small optical depth (9.6 versus 13.7). The differences are reduced by 50% when the CM averages are computed

  19. Diffusive Soil Degassing of Radon and Carbon Dioxide at San Miguel Volcano, El Salvador, Central America

    2001-12-01

    San Miguel volcano is located 15 km to the Southwest of San Miguel City (population ~300,000) and lies on the southern fault of the Central American graben at an intersection with NW-SE faults. The composition of San Miguel lavas varies from olivine-pyroxene basalts for the older lava flows to more andesitic compositions for the more recent products. This volcano have been degassing and having small ash emission since the late nineteen eighties. During December 1999 and January 2000, radon gas concentrations (pCi/l) in soils were measured using a Pylon AB5 radon monitor, and flux of CO2 (g/m2/day) was determined using the accumulation chamber method at 205 sampling stations. High gas emission inside the crater did not allow measurements to be taken in that region. CO2 fluxes throughout the soils of the volcanic edifice show low values compared to other active volcanoes of the world, suggesting that San Miguel is degassing preferentially throughout the summit region. CO2 fluxes range from less than 1 to 14 g/m2/day, with an average value of 5.6 g/m2/day. Radon concentrations range from 2 to 833 pCi/l with an average value of 110 pCi/l. Thoron concentrations range from 20 to 2178 pCi/l with an average value of 362 pCi/l. These values are comparable to radon concentrations found in other active volcanoes (e.g. Cerro Negro, Connor et al., 1996). CO2 flux, radon and thoron concentrations show higher values to the northwest and northeast faulted regions. Some anomalies seem to be related to the contact region between the older and more recent lava flows. Thoron/radon ratios show high anomalies aligning in the NW-SE direction where faulting also occurs. These results suggests that low permeability rocks forming the volcanic edifice of San Miguel volcano do not allow large fluxes of magmatic CO2 to be discharged throughout the soils. Higher permeability at faults and contacts allow slightly larger fluxes of CO2 and radon and thoron concentrations.

    Water frogs, Pelophylax perezi, that are introduced in the Azores, were screened for parasites using PCR primers known to amplify Apicomplexa parasites, and using nematode-specific primers. With the former, three different organisms were detected: Hepatozoon, a trichodinid protozoan ciliate and a possible Stramenopile. Using the latter set of primers, a single unknown spirurid nematode was also detected. Phylogenetic analyses indicate that Hepatozoon detected within amphibian hosts appear to form a clade, although relationships of these parasites do not match the vertebrate intermediate host phylogeny. Regarding the possible Stramenopile, it is unclear whether this organism was actually present on the amphibian or in the water on the surface of the tissue sample. Our findings highlight that many different organisms can be detected with these primers and that they can be used to screen introduced host populations to detect parasites that have been brought with them.

    Full Text Available This work describes and identifies the macroscopic and corresponding microscopic changes of the gonads of an important commercial fish species, Helicolenus dactylopterus dactylopterus, from Azores Archipelago. The new contribution relates the macroscopic scale with the histological stages. The annual changes in the gonad, together with the analysis of the monthly gonadosomatic indices, and complementary observations with scanning electron microscopy, allow us to conclude that the females are internally inseminated between July and November and spawn between January and March. There is a separation between female and male reproductive cycles. The overall sex-ratio observed was 1:1, but seasonal and length related differences were observed. This suggests differences and changes in availability, probably related to the annual reproductive cycle and changes in feeding behaviour

    Common dolphins (Delphinus delphis) are responsible for the large majority of interactions with the pole-and-line tuna fishery in the Azores but the underlying drivers remain poorly understood. In this study we investigate the influence of various environmental and fisheries-related factors in promoting the interaction of common dolphins with this fishery and estimate the resultant catch losses. We analysed 15 years of fishery and cetacean interaction data (1998–2012) collected by observers placed aboard tuna fishing vessels. Dolphins interacted in less than 3% of the fishing events observed during the study period. The probability of dolphin interaction varied significantly between years with no evident trend over time. Generalized additive modeling results suggest that fishing duration, sea surface temperature and prey abundance in the region were the most important factors explaining common dolphin interaction. Dolphin interaction had no impact on the catches of albacore, skipjack and yellowfin tuna but resulted in significantly lower catches of bigeye tuna, with a predicted median annual loss of 13.5% in the number of fish captured. However, impact on bigeye catches varied considerably both by year and fishing area. Our work shows that rates of common dolphin interaction with the pole-and-line tuna fishery in the Azores are low and showed no signs of increase over the study period. Although overall economic impact was low, the interaction may lead to significant losses in some years. These findings emphasize the need for continued monitoring and for further research into the consequences and economic viability of potential mitigation measures. PMID:27851763

    Full Text Available Assessment of underwater noise is of particular interest given the increase in noise-generating human activities and the potential negative effects on marine mammals which depend on sound for many vital processes. The Azores archipelago is an important migratory and feeding habitat for blue (Balaenoptera musculus, fin (Balaenoptera physalus and sei whales (Balaenoptera borealis en route to summering grounds in northern Atlantic waters. High levels of low frequency noise in this area could displace whales or interfere with foraging behavior, impacting energy intake during a critical stage of their annual cycle. In this study, bottom-mounted Ecological Acoustic Recorders were deployed at three Azorean seamounts (Condor, Açores, and Gigante to measure temporal variations in background noise levels and ship noise in the 18–1,000 Hz frequency band, used by baleen whales to emit and receive sounds. Monthly average noise levels ranged from 90.3 dB re 1 μPa (Açores seamount to 103.1 dB re 1 μPa (Condor seamount and local ship noise was present up to 13% of the recording time in Condor. At this location, average contribution of local boat noise to background noise levels is almost 10 dB higher than wind contribution, which might temporally affect detection ranges for baleen whale calls and difficult communication at long ranges. Given the low time percentatge with noise levels above 120 dB re 1 μPa found here (3.3% at Condor, we woud expect limited behavioral responses to ships from baleen whales. Sound pressure levels measured in the Azores are lower than those reported for the Mediterranean basin and the Strait of Gibraltar. However, the currently unknown effects of baleen whale vocalization masking and the increasing presence of boats at the monitored sites underline the need for continuous monitoring to understand any long-term impacts on whales.

    Full Text Available In his exemplary novel El amante liberal, Miguel de Cervantes uses the oriental setting to question the conventional representations of matrimony, gender, masculinity and feminity, individualism and freedom. Unlike other contemporary texts, his novel does not establish an opposition between the Muslim and the Christian world, but instead subtly points to the parallels between the two. In the following, our interpretation will lead to a new understanding of the novel’s title as well as of its exemplarity. It will be demonstrated that the official (Christian discourse of love and matrimony takes on a new meaning when paralleled to its equivalent in the Muslim world.

    Full Text Available In this paper, we examine the works produced by Miguel Ciera against the backdrop of the Third Delimitation Expedition, which was sent by Portugal to explore the interior of South America between 1752 and 1756. As the astronomer and cosmographer of the demarcation team, this Paduan engineer sailed up Paraguay River all the way to the mouth of Jauru River and there, with his companions, he set the border line, thus substantiating at site the Treaty of Boundaries. It was during this expedition that Ciera gathered information to design his Mappa geographicum quo flumen Argentum, Paranà et Paraguay [¿], a beautiful atlas that he later bestowed upon King Joseph I in 1758. In addition to accurate geographic charts, the atlas included depictions of fauna, popular types and landscapes made in pencil and watercolor, forming the first set of images available of that region, which was named Pantanal as from the 18th century. Here, we analyze this specific piece and seek to demonstrate that it was not merely a beautiful atlas; in fact, it was a refined visual document with which Miguel Ciera offered the Portuguese monarch valuable information about the hinterland here the border line was laid.

    2014-04-07

    Owing to the catastrophic extinction events that occurred following the Holocene arrival of alien species, extant oceanic island biotas are a mixture of recently incorporated alien fauna and remnants of the original fauna. Knowledge of the Late Quaternary pristine island faunas and a reliable chronology of the earliest presence of alien species on each archipelago are critical in understanding the magnitude and tempo of Quaternary island extinctions. Until now, two successive waves of human arrivals have been identified in the North Atlantic Macaronesian archipelagos (Azores, Madeira, Selvagens, Canary and Cape Verde Islands): 'aboriginal', which is limited to the Canary Islands around two millennia ago, and 'colonial', from the fourteenth century onwards. New surveys in Ponta de São Lourenço (Madeira Island) have allowed us to obtain and date ancient bones of mice. The date obtained (1033 ± 28 BP) documents the earliest evidence for the presence of mice on the island. This date extends the time frame in which the most significant ecological changes occurred on the island. It also suggests that humans could have reached Madeira before 1036 cal AD, around four centuries before Portugal officially took possession of the island.

  7. The role of lithospheric processes on the development of linear volcanic ridges in the Azores

    2013-11-01

    Linear volcanic ridges (LVRs) are widespread along the Azores plateau and are often used as a tectonic marker of the surface stress field. Nevertheless, the mechanisms that drive the emplacement and development of these structures are not well established and they have been attributed to the plateau diffuse deformation, off-rift extension or the result of the interaction between a hotspot and the brittle lithosphere. This study hypothesizes that linear volcanic ridges are the result of magma emplacement into pre-existing damaged lithosphere, using a 3D finite-element representation of the brittle lithosphere and underlying ductile mantle, and assuming that the deformation is driven by plate boundary forces applied at the edges, as describe by global plate kinematic models. The brittle layer is described by an elastoplastic rheology with progressive damage, where fractures are assumed to be analogous to localized shear bands. The ductile mantle underneath is modeled as a viscoelastic layer that exerts a shear drag at the base of the brittle layer. The modeling shows that lithospheric processes alone can justify the spatial distribution of linear volcanic ridges, and even the development of the Faial Ridge. The factors controlling the fracturing pattern are the plate geometry and velocity boundary conditions, the shearing introduced at the East Azores Fracture Zone/Gloria fault limit and the interaction between the viscous mantle and the spatially varying brittle plate thickness. Along the Terceira Rift the predicted fractures match the orientation of the LVRs in the second (~ N135°-N140°) and third (N150° to N-S) sectors and provide an explanation for the arcuate shape of the rift itself. The brittle plate thickness variations are crucial for the development of the more recent LVRs, which are predicted to occur along the Faial Ridge. In the best fit model the top mantle viscosity is 1 × 1022 Pa s at 5-15 km depth, and the present-day fracture network takes ~ 3

    This true-color image of the Galapagos Islands was acquired on March 12, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra satellite. The Galapagos Islands, which are part of Ecuador, sit in the Pacific Ocean about 1000 km (620 miles) west of South America. As the three craters on the largest island (Isabela Island) suggest, the archipelago was created by volcanic eruptions, which took place millions of years ago. Unlike most remote islands in the Pacific, the Galapagos have gone relatively untouched by humans over the past few millennia. As a result, many unique species have continued to thrive on the islands. Over 95 percent of the islands' reptile species and nearly three quarters of its land bird species cannot be found anywhere else in the world. Two of the more well known are the Galapagos giant tortoise and marine iguanas. The unhindered evolutionary development of the islands' species inspired Charles Darwin to begin The Origin of Species eight years after his visit there. To preserve the unique wildlife on the islands, the Ecuadorian government made the entire archipelago a national park in 1959. Each year roughly 60,000 tourists visit these islands to experience what Darwin did over a century and a half ago. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC

    Santiago Island, the biggest and most populated island of the Cape Verde Republic, is characterised by limited surface waters and strong dependence on groundwater sources as the primary source of natural water supply for extensive agricultural activity and human use. However, as a consequence of the scarce precipitation and high evaporation as well as the intense overexploitation of the groundwater resources, the freshwater management is also in a delicate balance with saltwater at coastal areas. The time-domain electromagnetic (TDEM) method is used to locate the extent of saltwater intrusion in four important agricultural regions in Santiago Island; São Domingos, Santa Cruz, São Miguel, and Tarrafal. The application of this method in Santiago Island proves it to be a successful tool in imaging the fresh/saltwater interface location. Depths to the saline zones and extensions of saline water are mapped along eight TDEM profiles.

    2012-01-01

    The U.S. Geological Survey (USGS), in cooperation with San Miguel County, New Mexico, conducted a study to assess publicly available information regarding the hydrologic resources of San Miguel County and to identify data gaps in that information and hydrologic information that could aid in the management of available water resources. The USGS operates four continuous annual streamgages in San Miguel County. Monthly discharge at these streamgages is generally bimodally distributed, with most runoff corresponding to spring runoff and to summer monsoonal rains. Data compiled since 1951 on the geology and groundwater resources of San Miguel County are generally consistent with the original characterization of depth and availability of groundwater resources and of source aquifers. Subsequent exploratory drilling identified deep available groundwater in some locations. Most current (2011) development of groundwater resources is in western San Miguel County, particularly in the vicinity of El Creston hogback, the hogback ridge just west of Las Vegas, where USGS groundwater-monitoring wells indicate that groundwater levels are declining. Regarding future studies to address identified data gaps, the ability to evaluate and quantify surface-water resources, both as runoff and as potential groundwater recharge, could be enhanced by expanding the network of streamgages and groundwater-monitoring wells throughout the county. A series of seepage surveys along the lengths of the rivers could help to determine locations of surface-water losses to and gains from the local groundwater system and could help to quantify the component of streamflow attributable to irrigation return flow; associated synoptic water-quality sampling could help to identify potential effects to water quality attributable to irrigation return flow. Effects of groundwater withdrawals on streamflow could be assessed by constructing monitoring wells along transects between production wells and stream reaches

    Plastic pollution in the marine environment attracts much attention from both researchers and the general public. Plastic items and other debris are commonly observed everywhere in the ocean, from the surface down to the deep ocean floor. In this study, we analysed 45.2km of video footage, collected during 56 transects surveying the seafloor of the Faial-Pico Passage in order to quantify the abundance of marine litter and its interactions with benthic fauna. The footage was collected by a Remotely Operated Vehicle (ROV) and a manned submersible at depths ranging between 40 and 525m. The mean litter density in the passage was 0.26±0.03 items·100m(-1) (±SE) and was significantly higher between 151 and 250m compared to other depth strata. Overall, derelict fishing gear, mostly made of plastic, were the most common objects found on the seafloor, representing 64% of all items. Although we observed few evidence of direct deleterious effects by the litter, interactions with fauna were observed in more than half of the items. This study makes an important contribution in quantifying the abundance of marine litter on the seafloor of the Azores. The location of the Faial-Pico Passage, close to shore, makes it an appropriate site for long-term monitoring of litter on the seafloor and evaluate the efficiency of upcoming public policies aimed at reducing litter input into the oceans.

    Islands with horizontal scales of the order of tens of km, as is the case of the Atlantic Islands of Macaronesia, are subscale orographic features for Global Climate Models (GCMs) since the horizontal scales of these models are too coarse to give a detailed representation of the islands' topography. Even the Regional Climate Models (RCMs) reveals limitations when they are forced to reproduce the climate of small islands mainly by the way they flat and lowers the elevation of the islands, reducing the capacity of the model to reproduce important local mechanisms that lead to a very deep local climate differentiation. Important local thermodynamics mechanisms like Foehn effect, or the influence of topography on radiation balance, have a prominent role in the climatic spatial differentiation. Advective transport of air - and the consequent induced adiabatic cooling due to orography - lead to transformations of the state parameters of the air that leads to the spatial configuration of the fields of pressure, temperature and humidity. The same mechanism is in the origin of the orographic clouds cover that, besides the direct role as water source by the reinforcement of precipitation, act like a filter to direct solar radiation and as a source of long-wave radiation that affect the local balance of energy. Also, the saturation (or near saturation) conditions that they provide constitute a barrier to water vapour diffusion in the mechanisms of evapotranspiration. Topographic factors like slope, aspect and orographic mask have also significant importance in the local energy balance. Therefore, the simulation of the local scale climate (past, present and future) in these archipelagos requires the use of downscaling techniques to adjust locally outputs obtained at upper scales. This presentation will discuss and analyse the evolution of the CIELO model (acronym for Clima Insular à Escala LOcal) a statistical/dynamical technique developed at the University of the Azores

    Full Text Available The reduced critical attention paid by philologists to Miguel Sánchez, poet and playwright who enjoyed considerable fame in the years of change between the 16th and 17th century, is astonishing. Authors like Rojas Villandrando, Cervantes and several others have devoted sincere praise to Sánchez. Lope de Vega refers to him several times with heartfelt admiration and in the Arte nuevo de hacer comedias credits his theatrical invention of «deceiving with the truth». After Stefano Arata’s monography, Miguel Sánchez begins to be recognized as a playwright in the theater of the Golden Age, but no one had cared to gather, edit and study his poetry. This paper provides a handful of verses allowing us to discover his original idiosyncrasy and versatility as a poet. Furthermore, some comical features of this poetic corpus give us clear reasons for the author’s success among contemporaries and perhaps the inner motives of his silent disappearance of the literary scene in the first decade of the 17th century.Sorprende la escasa atención de la filología hacia un poeta y dramaturgo como Miguel Sánchez que gozó de fama notable a finales del siglo XVI y principios del XVII.

    2015-12-01

    In this paper we presented synthetic acceleration records in the Miguel Hidalgo refinery, Hidalgo due to a seismic scenario originated in the graben Acambay, such as occurred in 1912 (70 km distance to it). This earthquake had a magnitude of 6.9 and caused extensive damage, according to reports caused 164 deaths and numerous houses collapsing. To simulate the event of M = 6.9 we used the empirical Greeńs function method proposed by Irikura (1986). Due to the low seismic activity we have not any small earthquake record or an "element earthquake" so that we generated a synthetic seismogram of M = 4.1 to be used as empirical Greeńs function. The seismogram was constructed in two parts. For low frequencies we constructed from cross-correlations of seismic noise, while for high frequencies we made a stochastic simulation. Subsequently, we applied a "matched filter" to join the two frequency bands of synthetic earthquake. For the construction of seismic scenario the method of Irikura (1986) was used. We consider a square fault of 47.75 km long, a radial rupture propagation, rupture velocity of 3.06 m/s, and with the following focal mechanism: strike of 280°, dip of 66 ° and rake of -138 °. With these parameters we obtained the synthetic seismograms. Since there was not any observed earthquake to validate the model, the 1912 event was simulated and then from relationships of intensity (obtained Wald et al.,2005; Sandoval et al., 2013; and Arias, 1969), we estimated the Modified Mercalli Intensity (MMI) for the refinery. We compare our result with isoseismal map obtained by Suter et al. (1996) for the earthquake of 1912. In agreement with Suter, our results shown a MMI V-VI for the Miguel Hidalgo refinery. With this qualitative validation we search the seismic scenario with the higher accelerations and from this synthetic seismogram, we obtained parameters that are of interest in engineering to estimate the possible affectations to the Miguel Hidalgo refinery, such as

    In a rural village located near San Miguel de Allende in the State of Guanajuato, Mexico, lung cancer is the primary cause of death. Medical and mortality records show that near to 40% of the deaths correspond to different neoplasms of the lung and near to 10% to malignant mesothelioma. Epidemiological and environmental surveys are conducted to provide insight into the causes of this health problem. Erionite was found in altered volcanic tuffs nearby the village and in fine-granular materials used for the construction of adobe houses in the past. Preliminary results relate erionite fibers as the main carcinogenic agent with almost the same annual rate of deaths by mesothelioma than in the Cappadocian region of Turkey.

    This paper presents an interview with Miguel Sabido, a writer-producer-director of theater and soap operas in Mexico concerning the social uses of commercial soap operas. According to Sabido, television soap operas can play multiple roles in educating the public: 1) melodramatic soap operas represent a mediation between good and bad; 2) soap operas allow people to gossip on different characters, their dilemmas, and create a climate for social change, especially if it centers on key social issues; and 3) soap operas provide role models to emulate. Sabido stressed the importance of a theory-based method for producing drama and mentioned how theoreticians Bentley, Bandura, Maclean, and Jung influenced his writing and production of soap operas. According to Sabido, the social uses of commercial television are possible with socially responsible soap operas.

    Full Text Available La publicación de los sonetos incluidos en El rayo que no cesa puso de relieve que Miguel Hernández aprendió a construirlos en los clásicos de nuestro Siglo de Oro y, entre ellos, quizá más aún que en ningún otro, en Lope de Vega, al que por aquellos años seguía igualmente de forma muy fiel en sus dramas Los hijos de la piedra y El labrador de más aire. En El rayo que no cesa logró, sin embargo, una cierta independencia y originalidad al conseguir revitalizar un esquema clásico y al obtener de él resultados óptimos en todos y cada uno de los poemas que componen su libro publicado en 1936, tras las conmemoraciones del centenario de Lope en 1935.

    Full Text Available More than any other member of his (post-war generation, Miguel Fisac was the epitome of the modern architect. His oeuvre spanned the second half of the twentieth century. With over 60 years in the profession and author of more than 450 designs, Fisac was one of the longestlived and prolific Spanish architects. But he never failed to mention the two battles he lost: town planning and social housing. Neither ever made it past the design stage: the first, embodied in the theories set out in his book La molécula urbana (The urban molecule and the second, in his patents for precast prestressed concrete systems that he was never able to implement.La personalidad de Miguel Fisac aglutina mejor que la de ningún otro de su generación, en los años de posguerra, la figura del arquitecto moderno por antonomasia. Su trabajo recorre toda la segunda mitad del siglo XX. Con más de 60 años de profesión y más de 450 proyectos, Fisac ha sido uno de los arquitectos más longevos y más prolíficos de nuestro país pero, aun así, siempre menciona sus dos grandes batallas perdidas: el urbanismo y la vivienda social. Ambas han quedado simplemente en un intento: la primera, desde sus teorías formuladas en su libro La molécula urbana, y la segunda, desde sus patentes de sistemas prefabricados de hormigón pretensado que no ha conseguido llevar a cabo.

    Full Text Available Endomarketing ou marketing interno são ações de Marketing voltadas para o público interno das empresas. O artigo que se apresenta a seguir foi baseado em uma pesquisa de campo financiada pelo Projeto PIC SENAC realizada na cidade de São Miguel do Oeste/SC, no ano de 2010, onde, em um primeiro momento, pesquisou-se os gestores das empresas que eram associados à Câmara de Dirigentes Lojistas naquele ano. Com os rumos daquela pesquisa, buscou-se, no ano de 2011, trabalhar uma segunda etapa, desta vez, pesquisando os funcionários das empresas cadastradas na Câmara de Dirigentes Lojistas (CDL da mesma cidade. Os pesquisadores procuraram identificar o grau de uso de algumas ferramentas do Endomarketing nas empresas da referida cidade, na visão dos funcionários. Neste estudo, trabalhamos com pesquisa bibliográfica e exploratória. A partir deste estudo, buscamos cruzar alguns dados a fim de diagnosticar se realmente as informações apresentadas pelos gestores no ano de 2010 condiziam com a visão dos funcionários na etapa de 2011. Percebemos com esta pesquisa que o uso de algumas ferramentas do endomarketing por parte das empresas de São Miguel do Oeste ainda é pequeno. Também constatamos, ao longo deste estudo, que trabalhar o capital humano dentro das organizações trará resultados positivos para elas, pois, quando os funcionários estão motivados, certamente seus trabalhos refletem no público externo (consumidores das empresas.

    Full Text Available In this document we analyze the decision making process on tourism in San Miguel Almaya, Mexico, an Otomi locality which preserves uses and customs based on the regime of communal land tenancy, yet slowly this community has experienced transformation basically as a result from its transition from agricultural to commercial community in recent decades. The analysis was based on the approach of Policy Networks that studies the relations generated among actors gathered around public problems; in this particular case: ecologic, normative, cultural and technical, among other associated at a different extent with tourism, which hinder sustainable conditions for their inhabitants. The methodology employed was based on the proposal by Cruz (2008 that identifies the objectives and interests of the actors respect to touristic activity and its linked actions; the resources they used and the cooperative relations established to reach their ends, as well as the dependence observed with other member of the policy network constructed as an abstraction of the complex fabric of interactions in the reality of San Miguel Almaya. The documental revision, in particularly of specialized literature, in-depth interviews with key actors, fieldwork and continual meetings with local authorities provided elements to analyze the political game unfolded by local and municipal authorities, private actors and the academy, all of them members of the network. As a result we detected how some uses and customs have been surpassed by economic, social and cultural transformations and their repercussions on the natural and cultural heritage of the community, which consequently compromise tourism that is the articulating axis of actions headed to rescue, exploitation and preservation of the forest, lake, religious festivities, identity, communal labor and urban image.

    The Padre Miguel Group in western Honduras is a silicic volcanic sequence that forms part of the Central American Miocene volcanic arc built on the Chortis continental fragment. We report new 40Ar/39Ar data of 16.1 ± 0.2 Ma and 14.42 ± 0.08 Ma for the Padre Miguel Group, and present paleomagnetic data for 36 cooling units (mainly ignimbrites) from localities north and northeast of the capital city of Tegucigalpa. These rocks are characterized by univectorial characteristic magnetization carried mainly by low-Ti titanomagnetites, or two component magnetizations with a minor secondary overprint. Dual polarity magnetizations suggest that it is a primary thermo-remanence and the obtained data scatter can be straightforwardly explained by paleosecular variation. The overall mean of 33 selected sites (14.39°N, 87.14°W) defines a paleomagnetic pole at lat = 80.0°N, lon = 142.9°E (K = 24.5, A95 = 5.2°). The overall mean compared with the North America expected direction indicates statistically insignificant rotation and inclination anomaly (R = - 4.1° ± 6.1° and an F = - 8.6° ± 11.3°). Restoring 255 km of sinistral slip in the Polochic-Motagua fault system, as suggested by Cayman Trough reconstructions since 15 Ma, brings the mid-Miocene arcs of southern Mexico (Oaxaca) and the Central America ignimbrite province into alignment; this is consistent with a derivation of the Chortis Block from southern Mexico. Our paleomagnetic and geochronological studies hence support models that explain the offset of the Miocene ignimbrite belt of Central America by post-Middle Miocene displacement of the Chortis Block relative to North America.

  16. Definition of a methodology for the management of geological heritage. An application to the Azores archipelago (Portugal)

    2013-04-01

    The conservation of the geological heritage requires the support of appropriate policies, which should be the result of the integration of nature conservation, environmental and land-use planning, and environmental education perspectives. There are several papers about inventory methodologies for geological heritage and its scientific, educational and tourism uses (e.g. Cendrero, 2000, Lago et al., 2000; Brilha, 2005; Carcavilla et al., 2007). However, management methodologies for geological heritage are still poorly developed. They should be included in environmental and land-use planning and nature conservation policies, in order to support a holistic approach to natural heritage. This gap is explained by the fact that geoconservation is a new geoscience still needed of more basic scientific research, like any other geoscience (Henriques et al., 2011). It is necessary to establish protocols and mechanisms for the conservation and management of geological heritage. This is a complex type of management because it needs to address not only the fragile natural features to preserve but also legal, economic, cultural, educational and recreational aspects. In addition, a management methodology should ensure the geosites conservation, the local development and the dissemination of the geological heritage (Carcavilla et al., 2007). This work is part of a PhD project aiming to contribute to fill this gap that exists in the geoconservation domain, specifically in terms of establishing an appropriate methodology for the management of geological heritage, taking into account the natural diversity of geosites and the variety of natural and anthropic threats. The proposed methodology will be applied to the geological heritage of the Azores archipelago, which management acquires particular importance and urgency after the decision of the Regional Government to create the Azores Geopark and its application to the European and Global Geoparks Networks.

    The aim of this study is to assess evaluation the tsunamigenic potential of the Azores-Gibraltar Fracture Zone (AGFZ). This work is part of the French project TANDEM (Tsunamis in the Atlantic and English ChaNnel: Definition of the Effects through numerical Modeling; www-tandem.cea.fr), special attention is paid to French Atlantic coasts. Structurally, the AGFZ region is complex and not well understood. However, a lot of its faults produce earthquakes with significant vertical slip, of a type that can result in tsunami. We use the major tsunami event of the AGFZ on purpose to have a regional estimation of the tsunamigenic potential of this zone. The major reported event for this zone is the 1755 Lisbon event. There are large uncertainties concerning source location and focal mechanism of this earthquake. Hence, simple deterministic approach is not sufficient to cover on the one side the whole AGFZ with its geological complexity and on the other side the lack of information concerning the 1755 Lisbon tsunami. A parametric modeling environment Promethée (promethee.irsn.org/doku.php) was coupled to tsunami simulation software based on shallow water equations with the aim of propagation of uncertainties. Such a statistic point of view allows us to work with multiple hypotheses simultaneously. In our work we introduce the seismic source parameters in a form of distributions, thus giving a data base of thousands of tsunami scenarios and tsunami wave height distributions. Exploring our tsunami scenarios data base we present preliminary results for France. Tsunami wave heights (within one standard deviation of the mean) can be about 0.5 m - 1 m for the Atlantic coast and approaching 0.3 m for the English Channel.

    2017-06-01

    Full Text Available Miguel del Prado, a painter who formed a company with Miguel Esteve in order to paint the now-lost Valencia town hall chapel in 1519, is an artist for whom there is scant documentary evidence. He has been identified with the anonymous Master of the Grifo, but this has been questioned recently. The author here offers news of a contract given to del Prado for an altarpiece in the Rosary Chapel of the old convent of Santo Domingo in Valencia that he was unable to fulfill due to his untimely death. It has been possible to certify that he perished on the battlefield of Almenara during the Germanías Revolt of 1521. Therefore the chronology for this painter has now been reduced by more than 16 years, because he was thought to have died in 1537.

  7. Assessment of the ocean circulation in the Azores region as predicted by a numerical model assimilating altimeter data from Topex/Poseidon and ERS-1 satellites

    Directory of Open Access Journals (Sweden)

    T. Mailly

    Full Text Available Two years of altimetric data from Topex/Poseidon (October 1992–September 1994 and ERS-1 (October 1992–December 1993 were assimilated into a numerical model of the North Atlantic. The results of these simulations are analysed in the Azores region to assess the performance of our model in this particular region. Maps of instantaneous dynamic topography and transports show that the model performs well in reproducing the velocities and transports of the Azores Front. Drifter data from the Semaphore experiment are also used to study the correlation between the drifter velocities and the corresponding model velocities. Some interesting oceanographic results are also obtained by examining the seasonal and interannual variability of the circulation and the influence of bathymetry on the variability of the Azores Front. Thus, on the basis of our two year experiment, it is possible to confirm the circulation patterns proposed by previous studies regarding the seasonal variations in the origin of the Azores Current. Moreover, it is shown that the Azores Current is quite narrow in the first year of assimilation (1992–1993, but becomes much wider in the second year (1993–1994. The role of the bathymetry appears important in this area since the mesoscale activity is shown to be strongly related to the presence of topographic slopes. Finally, spectral analyses of sea-level changes over time and space are used to identify two types of wave already noticed in other studies: a wave with (300 km–1 wave number and (120 days–1 frequency, which is characteristic of mesoscale undulation, and a wave with (600 km–1 wave number and (250 days–1 frequency which probably corresponds to a Rossby wave generated in the east of the basin.

  8. Nuances in the representation of time in the works of Miguel Delibes

    Directory of Open Access Journals (Sweden)

    Maria-Teresa De Pieri

    2012-12-01

    Full Text Available This work analyzes the representation of time and its nuances in the novels and newspaper articles of Miguel Delibes. The category of time is related to an idea of existence that follows the cycles of nature; it is a natural and mythical time, both a personal and collective one, whose fleeting nature can be halted only by the power of words. In his works Delibes tries to preserve a vocabulary on the verge of extinction in today’s day and age. The ironic tone in which he reflects on the relentless fl owing of existence – such as in La hoja roja, Cartas de amor de un sexagenario voluptuoso and other articles – is juxtaposed to a more serious and careful tone adopted for instance, in Viejas historias de Castilla la Vieja (1964. Moreover, the theme of death is linked to the passing of time. In Señora de rojo sobre fondo gris Delibes analyzes it as a reflection of his tough personal experience, while in Cinco horas con Mario the author takes advantage of the absence of the male protagonist, who has just died, in order to reflect on the abyss separating the present from the past.

    2017-02-01

    Full Text Available Pervasive social and ecological water crises in Mexico remain, despite over two decades of legal and institutional backing for Integrated Water Resources Management (IWRM as a policy tenet. In this article we apply a socialshed analysis to uncover and understand the geographical and jurisdictional forces influencing the social construction and simultaneous fragmentation of the San Miguel Watershed (SMW in the state of Sonora, in Mexico’s water-scarcity bulls-eye. Specific insights derived from an empirical analysis include that water management (WM is socially embedded in dense networks of family and friends, farmers and ranchers, citizens and local government – all to varying degrees sharing information about local water crises. Irrigation water user representatives (WUR are connected across communities and within their own municipalities, but inter-watershed social links with other WUR are virtually nonexistent, despite high levels of awareness of cross-municipality WM problems. Implementation of IWRM as a federal policy by a single agency and the creation of basin councils and subsidiary technical committees for groundwater management have not been sufficient for technical – much less social – integration at the watershed level. This study shows that the SMW socialshed remains fragmented by local jurisdictions; without coordinated agency-jurisdiction-local action fomenting social connections, a socialshed will not emerge.

  12. Embodied Cognition and Empathy in Miguel de Cervantes's El celoso extremeño.

    Science.gov (United States)

    Carrera, Elena

    2014-03-01

    This article examines the portrayal of cognitive experience in the published version of Miguel de Cervantes's short story El celoso extremeño (1613), drawing both on recent studies of empathy and current debates about the inseparability of cognition and emotion. It considers how cognitive experience is marked by particular bodily sensations and shaped by internal representations (i.e., mental images) that are closely tied to emotions such as fear, jealousy, joy, and sorrow. Paying particular attention to the ways in which the narrative underscores the characters' limited sensory experiences and their defective understanding of each other's positions, the article argues that this provides the reader with the opportunity to simulate mentally his or her own challenging situations, faulty judgments, and injudicious actions. While being invited to use his or her imagination and judgment to enjoy being placed in a position of greater power and knowledge than the characters, Cervantes's reader is also encouraged to consider the possibility of not knowing and to accept the limits of empathy.

  13. Problems and constraints in Philippine municipal fisheries: The case of San Miguel Bay, Camarines Sur

    Lim, Cristina P.; Matsuda, Yoshiaki; Shigemi, Yukio

    1995-11-01

    The Philippine fisheries accounted for 3.7% of the gross national product at current prices. The sector employed about 990,872 persons. Of the divisions comprising the industry, municipal fisheries continued to contribute the largest share of fish production. However, the sector is beset with problems, many of which are best examplified by the case of San Miguel Bay (SMB). This paper presents the problems and constraints confronting SMB, a common property resource. This bay's open access condition has led to various problems, such as declining fishery resources, depressed socioeconomic conditions, illegal fishing, increasing population, and conflict among resource users. A poor marketing system, low level of fishing technology, fishermen's noncompliance and authorities' lax enforcement of rules and regulations, as well as lack of alternative sources of income further characterize the condition in SMB. Establishment of fishing rights, improvement of the marketing system, provision of alternative sources of income, and improvement of fishing technology were some of the solutions suggested. One major constraint, however, is financial, Comanagement complemented with other management tools has been proposed in addressing the problems in SMB.

The major motivation for such a geographical location choice was the abundance of renewable resources like wind, sea waves and geothermal enthalpy, which are of fundamental importance for the demonstration of renewable hydrogen economy sustainability. Three main campus will be implemented: one at Cume Hill, where the majority of renewable hydrogen production will take place using the wind as the primary energy source, a second one at Angra do Heroismo Industrial park, where a cogen electrical – heat power station will be installed, mainly to feed a Municipal Solid Waste processing plant and a third one, the Praia da Vitoria Hydrogenopolis, where several final consumer demonstrators will be installed both for public awareness and intensive study of economic sustainability and optimization. Some of these units are already under construction, particularly the renewable hydrogen generation facilities.

    San Miguel volcano, also known as Chaparrastique, is a basaltic volcano along the Central American Volcanic Arc (CAVA). Volcanism is induced by the convergence of the Cocos Plate underneath the Caribbean Plate, along a 1200-km arc, extending from Guatemala to Costa Rica and parallel to the Central American Trench. The volcano is located in the eastern part of El Salvador, in proximity to the large communities of San Miguel, San Rafael Oriente, and San Jorge. Approximately 70,000 residents, mostly farmers, live around the crater and the city of San Miguel, the second largest city of El Salvador, ten km from the summit, has a population of ~180,000 inhabitants. The Pan-American and Coastal highways cross the north and south flanks of the volcano.San Miguel volcano has produced modest eruptions, with at least 28 VEI 1-2 events between 1699 and 1967 (datafrom Smithsonian Institution http://www.volcano.si.edu/volcano.cfm?vn=343100). It is characterized by visible milddegassing from a summit vent and fumarole field, and by intermittent lava flows and Strombolian activity. Since the last vigorous fire fountaining of 1976, San Miguel has only experienced small steam explosions and gas emissions, minor ash fall and rock avalanches. On 29 December 2013 the volcano erupted producing an eruption that has been classified as VEI 2. While eruptions tend to be low-VEI, the presence of major routes and the dense population in the surrounding of the volcano increases the risk that weak explosions with gas and/or ash emission may pose. In this study, we present the first inventory of SO2, CO2, HCl, and HF emission rates on San Miguel volcano, and an analysis of the hazard from volcanogenic SO2 discharged before, during, and after the December 2013 eruption. SO2 was chosen as it is amongst the most critical volcanogenic pollutants, which may cause acute and chronicle disease to humans. Data were gathered by the geochemical monitoring network managed by the Ministerio de Medio Ambiente

    Full Text Available Durante el siglo XIX, las vivas polémicas ideológicas sobre la conquista y la colonización de América, se intensificaron entre las elites latinoamericanas. El caso ejemplar fue el del conservador ultramontano Miguel Antonio Caro (1843-1909, militante activo del partido nacionalista de la “Regeneración” y ejecutor como también promotor principal de la “Constitución de 1886”. Su proyecto político concebido como misional y patriótico fue enfurecido en la disutopía que planteó, la de salvaguardar la herencia española y desestimar la ruptura peninsular, que tantos liberales radicales del continente exigieron como presupuesto de desarrollo y civilización de nuestros pueblos. El siguiente artículo hace una estimación de las principales ideas que Caro tuvo frente al problema sociopolítico de las independencias latinoamericanas, la polémica pasional que desató en su defensa de España como su acendrada y acérrima recuperación de la civilización hispánica en nuestros territorios. Al cumplirse los 200 años de nuestro proceso de emancipación, este escrito brinda la posibilidad de repensarnos en la construcción de nuestra identidad y construcción de la nacionalidad, a partir de uno de los líderes, dirigentes y batalladores insignes del pensamiento latinoamericano.

    Full Text Available This article focuses in the relationships between subject and space in El camino and Mi idolatrado hijo Sisí, by Miguel Delibes. Both novels show the reflection on infantry, the formative process and the environment. An important difference appears in the contrast of city and the country area, symbolically present and past. In the two texts there is not a single thesis about man and society, but what the reader has, through dialogues, third person narrative and free indirect style, is a consciousness deciding freely. When we try to establish a relationship between both novels, their time and space, it seems that the second could be in the origin of a society that produces a critical answer in the reader.Este artículo se centra en el examen de algunas relaciones entre el sujeto y el espacio. En las dos novelas de Delibes existe una preocupación por la infancia, el proceso de formación y el medio social. Una diferencia básica tiene que ver con la separación del medio rural, en El camino, y el ciudadano, en Mi idolatrado hijo Sisí. La narración no se configura para mantener una tesis, sino que vemos, a través de la tercera persona, del diálogo y el estilo directo libre, una conciencia decidiendo libremente. Si relacionamos los dos textos, su espacio y tiempo, es la segunda la que parece estar en el origen de una configuración social en la que la respuesta del lector debe ser crítica.

    Full Text Available The study aimed to analyze the Passion for Philippine Social Transformation in the Novel Ilustrado of Miguel Syjuco. In view of the prevailing social problems encountered in the Philippines such as social injustices, corruption, and the like, and the need for transformation or change of its societal structures, the researcher’s interest being a literature teacher is aroused or stimulated. The qualitative approach was used in this descriptive study of the novel of socio-political nature in order to project a social transformation through critical investigation on the values projected in it. Hence, the study used analytical approach, psychological approach, philosophical or moral/ethical approach, and sociological approach in analyzing its content. Results showed that social transformation in making wise preferences, having smooth family relationship, and decreasing social injustices apparently were the social transformations depicted in the novel. The author’s rejection to join politics and desiring to expose social ills were the major incidents in his life that showed his passion for social change. The structures of the society that needed to be changed were moral values of the leaders, personal interests, Filipinos culture, and the motives of the politicians to maintain their hold in power. The use of symbolism as the predominant literary device gave the readers clearer picture of the condition of the society and understanding of the author’s passion for Philippine social transformation. The moral ethical values of courage in saving other’s lives from devastation, honesty to self and to the country, devotion to Filipino writings and writers, faith in God, and forgiveness reflected in the story were made alive and real in the readers.

    Miguel Hidalgo Hospital in Aguascalientes is dependent from the Federal Secretary of Health and operates in integrity with State health system in Aguascalientes. It capacity is based on 132 censored beds and 71 no censored beds. Is considered a specialty hospital in the region of Bajío. Renal transplant program activity was initiated in 1990 and gives care for adult and pediatric population. Retrospective, comparative and longitudinal study to describe and analyze our experience. Data base and clinical charts of renal transplant recipients were reviewed. Age, gender, date of transplant, etiology of renal disease, type of donor, HLA compatibility and PRA, immunosuppressive therapy, acute rejection, serum creatinina, graft loss and mortality were registered. Statistical analysis included 2, unpaired Student T test and Kaplan-Meier survival analysis with Log Rank test. Cox Analysis was also done. 1050 renal transplants were done from November 1990 to June 2011. 50 were excluded because follow-up was not longer than 3 months. 1000 consecutive renal transplant patients from January 1995 to June 2011 were included for analysis. Patients were divided in 2 groups: group A transplanted January 1995 to December 2004; group B transplanted January 2005 to June 2011. Etiology for end stage renal disease is unknown in 61% of cases, 11% developed renal disease to diabetes mellitus. 93% patient survival was observed at median follow-up and 84.9% graft survival at median follow-up (6 years). Biopsy proven acute rejection in group A 19.9 vs. 10% in group B. Two haplotype matching shows 92% graft survival. Diabetic patients exhibit 73% graft survival vs. other as hypertension (87%). PRA >0 and serum creatinine > 2.0 mg/dL increase risk for graft loss according to Cox analysis. CONCLUSION. Results are comparable to international data. Importance of developing regional transplant centers is emphasized.

    Full Text Available Agricultural societies in the state of Mexico involved a form of legal resistance used by indigenous communities in the face of liberal individualization policies of communal property, particularly the federal seizure law of June 25, 1956. In this context, some residents of the towns of Santa Cruz and San Miguel created an agricultural association, as did residents from the town of San Pedro, to retain the collective use of their communal goods and acquire some legal capacity. This condition thus allowed indigenous peoples to present writs of amparo to defend "private" rights.

  12. Modelling the extreme precipitation event over Madeira Island on 20 February 2010

    Full Text Available In the morning of the 20 February of 2010 an extreme precipitation event occurred over Madeira Island. This event triggered several flash floods and mudslides in the southern parts of the island, resulting in 42 confirmed deaths, 100 injured, and at least 8 people still missing. These extreme weather conditions were associated to a weather frontal system moving northeastwards embedded in a low pressure area centered in the Azores archipelago. This storm was one in a series of such storms that affected Portugal, Spain, Morocco and the Canary islands causing flooding and strong winds. These storms were bolstered by an unusually strong sea surface temperature gradient across the Atlantic Ocean.

    In this study, the WRF model is used to evaluate the intensity and predictability of this precipitation extreme event over the island. The synoptic/orographic nature of the precipitation is also evaluated, as well as the sensitivity of the model to horizontal resolution and cumulus parameterization. Orography was found to be the main factor explaining the occurrence, amplitude and phase of precipitation over the Island.

    Hematologic and serum biochemical data collected must be interpreted by comparison with normal reference intervals generated from healthy animals, within a similar population, because many blood parameters are influenced by diet, environment, and stress. Species-specific reference intervals for the endangered island fox (Urocyon littoralis) are not available. We reviewed hematology and serum biochemistry panels from 280 island foxes sampled from 1999-2008 and established normal reference intervals from clinically healthy foxes using a nonparametric approach. Blood parameters were analyzed for differences in age, sex, island of origin, and captivity status. Alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, and creatine kinase activities, as well as calcium and phosphorus concentrations, were significantly higher in juveniles than in adults, but total protein and globulin concentration was lower for juveniles than for adults. Lymphocyte and eosinophil counts, and blood urea nitrogen (BUN) concentration, in foxes from the northern Channel islands of California, USA (Santa Cruz, Santa Rosa, and San Miguel) were higher when compared with foxes from Santa Catalina Island to the south. Higher lymphocyte and eosinophil numbers in the northern island foxes may be associated with increased levels of parasitism on the northern islands. Differences in BUN concentration in both free-ranging and captive foxes may reflect dietary differences among islands. Although aggressive conservation programs have been enacted, island foxes are still susceptible to infectious and neoplastic diseases and, potentially, to toxins. Island fox species-specific reference intervals will enable managers and veterinarians to better care for sick and injured foxes and will contribute to future population health monitoring.

    The helminth parasite fauna of the oceanic horse mackerel Trachurus picturatus Bowdich 1825, caught off the Madeira Islands was composed of six different taxa. Prevalence and abundance of larval Anisakis sp. (Nematoda: Anisakidae) and Nybelinia lingualis (Trypanorhyncha: Tentaculariidae), the most common parasite taxa, were 24.3%, 0.9 and 37.9%, 0.7, respectively. Bolbosoma vasculosum (Acanthocephala: Polymorphidae) and the monogeneans Heteraxinoides atlanticus (Monogenea: Heteraxinidae) and Pseudaxine trachuri (Monogenea: Gastrocotylidae) were comparatively rare. The depauperate helminth fauna of the oceanic horse mackerel at Madeira compared to other geographical regions of the north-eastern Atlantic, namely the Azores banks and the West African coast, may be attributed to the paucity of nutrients off oceanic islands and to a low density of the fish population.

    Full Text Available The Azores Regional Government, through the Sustainable Energy Action Plan for the Azorean Islands, assumed that by the year 2018, 60% of electricity would be generated from renewable energy sources. Nevertheless, by increasing renewable energy sources share in the electricity mix, peak energy that exceeds grid capacity cannot be used unless when considering energy storage systems. Therefore, this article aims at determining, among batteries and Pumped Hydro Systems, the most cost-effective energy storage system to deploy in Terceira Island, along with geothermal, wind, thermal and bio waste energy, while considering demand and supply constraints. It is concluded that a pumped hydro system sited in Serra do Morião-Nasce Água is the best option for storage of the excess generated energy when compared with batteries. However, further studies should analyze environmental constraints. It is demonstrated that by increasing the storage power capacity, a pumped hydro system improves its cost efficiency when compared with batteries. It is also demonstrated that, to ensure quality, economic feasibility, reliability and a reduction of external costs, it is preferable to replace fuel-oil by wind to generate electricity up to a conceivable technical limit, while building a pumped hydro system, or dumping the excess peak energy generated.

    Full Text Available RESUMEN DEL TRABAJO Desde el establecimiento del Régimen franquista se creó el organismo de la censura que controlaba todo tipo de producción creativa e intelectual, entre ésta la novela. El insigne novelista español Miguel Delibes escribió su obra “Cinco horas con Mario” para difundir algunas ideas no afines al régimen, describir la escena sociopolítica del país y criticar algunos aspectos de la Dictadura. La obra cuenta la vida de un matrimonio español en las décadas posteriores a la Guerra Civil hasta 1966. Se trata de un prólogo, 27 capítulos y un epílogo. Los 27 capítulos, encabezados por textos bíblicos, son un monólogo larguísimo, en el cual la esposa de Mario cuenta su vida con su marido y la de su patria, antes que le entierran, muerto ya, y puesto en su despacho. Dado el carácter crítico de la obra, el autor utilizó diversas técnicas para escapar del control del organismo opresor. Éstas son aspectos costumbristas, de adulación, y desconcertantes. La característica general de todas estas es el uso del “perspectivismo irónico”, se trata de decir cosas autorizadas por parte del Régimen de una forma irónica que convierte los elogios en críticas. Las conclusiones son las siguientes: • La peligrosidad de ejercer la “autocensura”, pues, hace difícil al autor transmitir su mensaje con la claridad deseada. • Llamar la atención sobre la gran pérdida que sufrió el pueblo español debido a la actividad dañina de la censura. • La necesidad de estudiar otras obras similares para obtener resultados generales y cuantificar la magnitud del daño hecho por la censura.

    Species richness on oceanic islands has been related to a series of ecological factors including island size and isolation (i.e. the Equilibrium Model of Island Biogeography, EMIB), habitat diversity, climate (i.e., temperature and precipitation) and more recently island ontogeny (i.e. the General Dynamic Model of oceanic island biogeography, GDM). Here we evaluate the relationship of these factors with the diversity of bryophytes in the Macaronesian region (Azores, Madeira, Canary Islands and Cape Verde). The predictive power of EMIB, habitat diversity, climate and the GDM on total bryophyte richness, as well as moss and liverwort richness (the two dominant bryophyte groups), was evaluated through ordinary least squares regressions. After choosing the best subset of variables using inference statistics, we used partial regression analyses to identify the independent and shared effects of each model. The variables included within each model were similar for mosses and liverworts, with orographic mist layer being one of the most important predictors of richness. Models combining climate with either the GDM or habitat diversity explained most of richness variation (up to 91%). There was a high portion of shared variance between all pairwise combinations of factors in mosses, while in liverworts around half of the variability in species richness was accounted for exclusively by climate. Our results suggest that the effects of climate and habitat are strong and prevalent in this region, while geographical factors have limited influence on Macaronesian bryophyte diversity. Although climate is of great importance for liverwort richness, in mosses its effect is similar to or, at least, indiscernible from the effect of habitat diversity and, strikingly, the effect of island ontogeny. These results indicate that for highly vagile taxa on oceanic islands, the dispersal process may be less important for successful colonization than the availability of suitable ecological

    Full Text Available Zoantharians are a group of cnidarians that are often found in association with marine invertebrates, including corals, in shallow and deep-sea environments. However, little is known about deep-sea zoantharian taxonomy, specificity and nature of their associations with their coral hosts. In this study, analyses of molecular data (mtDNA COI, 16S, and 12S rDNA coupled with ecological and morphological characteristics were used to examine zoantharian specimens associated with cold-water corals (CWC at depths between 110 and 800 m from seamounts and island slopes in the Azores region. The zoantharians examined were found living in association with stylasterids, antipatharians and octocorals. From the collected specimens, four new species were identified: (1 Epizoanthus martinsae sp. n. associated with the antipatharian Leiopathes sp.; (2 Parazoanthus aliceae sp. n. associated with the stylasterid Errina dabneyi (Pourtalès, 1871; (3 Zibrowius alberti sp. n. associated with octocorals of the family Primnoidae [Paracalyptrophora josephinae (Lindström, 1877] and the family Plexauridae (Dentomuricea aff. meteor Grasshoff, 1977; (4 Hurlizoanthus hirondelleae sp. n. associated with the primnoid octocoral Candidella imbricata (Johnson, 1862. In addition, based on newly collected material, morphological and molecular data and phylogenic reconstruction, the zoantharian Isozoanthus primnoidus Carreiro-Silva, Braga-Henriques, Sampaio, de Matos, Porteiro & Ocaña, 2011, associated with the primnoid octocoral Callogorgia verticillata (Pallas, 1766, was reclassified as Zibrowius primnoidus comb. nov. The zoantharians, Z. primnoidus comb. nov., Z. alberti sp. n., and H. hirondelleae sp. n. associated with octocorals showed evidence of a parasitic relationship, where the zoantharian progressively eliminates gorgonian tissue and uses the gorgonian axis for structure and support, and coral sclerites for protection. In contrast, the zoantharian P. aliceae sp. n

    Full Text Available Cold-water corals are widely considered as important structural components of benthic habitats, potentially enhancing local abundance in a variety of fish and invertebrate species. Yet, current knowledge of the taxonomic diversity and distribution patterns of these vulnerable, slow-growing organisms is scarce and fragmented, limiting the effectiveness of spatial management and conservation measures. We have conducted an exhaustive compilation of records of alcyonaceans, antipatharians, scleractinians and stylasterids available until the present day to assess the diversity, distribution, and spatial structure of coral assemblages in the Azores Exclusive Economic Zone (EEZ. The resulting database comprises 2501 entries concerning historical oceanographic expeditions and other published sources, as well as recent data from longline bycatch. Our taxonomic inventory appears to be fairly complete for the explored habitats, accounting for 164 species (79 alcyonaceans, 58 scleractinians, 18 antipatharians and 9 stylasterids, nine of which were new records. The Azores EEZ harbours a mixed coral fauna with several zoogeographic origins, showing the closest affinity with the Lusitanian–Mediterranean region. Very few apparent endemics were found (14%, and only in part supported by consistent sampling. Coral diversity is particularly high between 300 and 900 m depths, in areas recognized as traditional fishing grounds or exploitable fish habitat within the 100-mile limit of the EEZ. The composition of coral assemblages shows significant geographical structure among longitudinal sections of the study area at comparable depths (100–1500 m. There is no evidence of a possible role of the Mid-Atlantic Ridge or latitudinal effects underlying this pattern, which suggests that it may instead reflect assemblage variability among features. Stronger changes in species composition were found along the bathymetric gradient. Notwithstanding the mix of partially

    Full Text Available GEODYNAMICS AND NATURAL HAZARDS IN THE AZORES ISLANDS. The central islands of the Azores archipelago exhibit significant volcanic and seismic activity. The most important tectonic structure responsible for this activity seems to be the leaky transform Terceira Rift, a branch of the Azores triple junction separating the Eurasia and Africa plates. In historical time (since the XV century, the most frequent volcanic eruptions were of the hawaiian and strombolian types, but the level of explosivity has occasionally reached subplinian magnitude, as it happened in the Fogo (1563 and Furnas (1630 volcanoes (hydromagmatic eruptions in the calderas. As in other volcanic regions of the world, effusive volcanism is not particularly dangerous in the Azores islands; explosive activity, however, can be catastrophic (ignimbrites formed in some islands over the last millennia. Still, throughout historical time, earthquakes have been the most dangerous natural phenomena in the Azores, sometimes bringing about tragic consequences: in 1757, an earthquake struck the São Jorge island, killing one thousand people (20% of the total population. But the most catastrophic seismic event of all occurred in the island of São Miguel in 1522: an earthquake triggered an earthflow that submerged the capital (Vila Franca do Campo and killed nearly all of its inhabitants (several thousands. Whether or not they are triggered by earthquakes, mass movements are most common along the coast of the islands: huge falls and rotational slides are attested for by the so-called fajãs, detrital platforms on the foot of cliffs that are several hundred meters high; in death-defying fashion, some of these platforms are actually inhabitated.

    Full Text Available Fossil fish teeth are contained in marine deposits dated at ca 4.8 Ma found on the islands of Gran Canaria and Fuerteventura (Canary Islands, Spain. These islands, situated in the North Atlantic Subtropical Gyre, can be considered a mid-way stopover point between the Caribbean Sea, with the Central American Seaway about to close in this epoch, and the Mediterranean, in the first stage of its post-Messinian Gibraltar Seaway period. Accordingly, there existed extensive pantropical communication, particularly for nektonic animals capable of travelling large distances. In this paper, we present a number of fossil fishes, most of which are identified for the first time on the basis of their teeth: the Chondrichthyes species Carcharocles megalodon, Parotodus benedeni, Cosmopolitodus hastalis, Isurus oxyrinchus, Carcharias cf. acutissima, Carcharhinus cf. leucas, Carcharhinus cf. priscus, Galeocerdo cf. aduncus, and the Osteichthyes species Archosargus cinctus, Labrodon pavimentatum, and Diodon scillae. Coincidences are observed between these ichthyofauna and specimens found in the Azores Islands, the Pacific coast of America and the Mediterranean Sea.

    Full Text Available The article herein shows some conceptual features of Miguel Antonio Caro’s intellectual project and its intrinsic strengths. Furthermore, it details the type of politicization which Caro imposed on some of the work of his contemporaries politicization which, in turn, was later imposed on him-self by contemporary historiography. More to the point, I evidence how Caro, when asserting that a particular text by Jorge Isaacs (The native tribes of the Magdalena basin was scientific, immediately proceeded to politicize Isaac’s work, among other things, because he (Caro did not have the relevant arguments needed to confront Isaacs’ text in its own terms and framework. Thus, in order to dismiss Isaacs’ objections raised against the government of Nuñez, Caro places the aforementioned work by the author of María, among the texts that threatened social order by presenting it as part and parcel of positivism, empiricism, liberalism, and all other intellectual efforts based on a damaging sensualism.//Aquí muestran algunos aspectos conceptuales del proyecto intelectual de Miguel Antonio Caro y su consistencia interna. Además, preciso el tipo específico de politización que este escritor impuso sobre algunos trabajos que le fueron contemporáneos –politización de la cual el mismo Caro ha sido objeto por parte de historiografía contemporánea–. Específicamente, presento cómo Miguel Antonio Caro, al afirmar que un texto de Isaacs (Las tribus indígenas del Magdalena es científico, politiza su trabajo por la imposibilidad de atacarlo dentro de los límites argumentativos del texto de Isaacs. De esta forma, para hacer a un lado las objeciones que Isaac eleva contra el gobierno de Núñez, Caro ubica el trabajo del autor de María en el grupo de escritos que amenazan el orden social, al presentarlo de la mano con el positivismo, empirismo, liberalismo y demás esfuerzos intelectuales fundados en un “nocivo” criterio sensualista.

    We relate fish biological and ecological characteristics to total and organic mercury concentrations to determine whether accumulation is influenced by trophic level, Hg concentration in the diet, and vertical distribution. Levels of total mercury and methylmercury were determined in the muscle tissue of eight species of fish: Pagellus acarne, Trachurus picturatus, Phycis phycis, P. blennoides, Polyprion americanus, Conger conger, Lepidopus caudatus and Mora moro, caught in the Azores. All such fishes are commercially valuable and were selected to include species from a wide range of vertical distributions from epipelagic (300 m) environments. Methylmercury was the major form accumulated in all species, comprising an average of 88.1% of total mercury. Concentrations of mercury (total and methylmercury) increased with age, length and weight. Based on data from other studies, mercury concentrations in fish diet were estimated. Mercury levels in food ranged from 0.08 to 0.32 ppm, dry weight. Hg concentrations in the food and in muscle tissue from different species were positively correlated. Total Hg levels in the muscles were approximately nine times those estimated in food. Total mercury concentrations in muscle were positively correlated with both trophic level and median depth. Such enhanced mercury bioaccumulation in relation to depth appears to be determined primarily by concentrations in food and ultimately by water chemistry, which controls mercury speciation and uptake at the base of the food chain.

The title of Unamuno's most famous work, Del Sentimiento Trágico de la Vida (The Tragic Sense of Life, refers to the human condition of the desire for immortality when faced with the certainty of death. According to Unamuno this desire to live forever is an irrational desire, but it is this desire that makes us human. Thus there is a conflict between our perpetual desire for immortality and our reason - which contradicts it; out of this conflict comes the desire to believe in God, which reason cannot confirm.

    Full Text Available Miguel Querol is mainly known as musicologist, although he was deeply interested in Philosophy and, specifically, in aesthetics and music thought. In this field, he wrote several articles on Joan Maragall, one of his favourite poets, besides vocal music based on texts by him, noteworthy the Cant espiritual. In this work we study how the latter piece synthesizes the style and thinking of both artists, becoming a reflection on art, creativity and the human being. Our approach is based on the analysis and comparison between the aesthetic postulates adopted by Querol and Maragall and the musical resources of Cant espiritual.Miguel Querol es conocido sobre todo como musicólogo, pero uno de los temas que más le interesó fue la filosofía y, en concreto, el pensamiento estético y musical. En este aspecto, Querol sintió especial predilección por Joan Maragall, sobre quien hizo diversos artículos y del que musicó algunos poemas, entre los cuales destaca el Cant espiritual. En este trabajo, a partir del análisis y la comparación entre los postulados estéticos de Querol y Maragall y los recursos musicales del Cant espiritual, se estudia cómo esta pieza sintetiza el pensamiento y estilo de ambos autores, convirtiéndose en una reflexión sobre el arte, la capacidad creativa del hombre y el ser humano en sí.

    Full Text Available A new Cryptorchestia species, Cryptorchestia ruffoi Latella & Vonk, sp. n. from the island of Rhodes in south-eastern Greece, can be distinguished on the basis of morphological and phylogenetic data. Morphological analysis and DNA sequencing of mitochondrial and nuclear protein-coding genes indicated that this species is related to C. cavimana (Cyprus and C. garbinii (Mediterranean regions, with a recent northward expansion. Results supported a genetic separation between the Cryptorchestia species of the east Mediterranean regions and those of the northeast Atlantic volcanic islands examined in this study (C. canariensis, C. gomeri, C. guancha, and C. stocki from the Canary islands, C. monticola from Madeira, and C. chevreuxi from the Azores. The Mediterranean and Atlantic Cryptorchestia species appear to be also morphologically distinct. Cryptorchestia ruffoi sp. n., C. cavimana, C. garbinii, and C. kosswigi (Turkish coast clearly have a small lobe on the male gnathopod 1 merus. This character was the main diagnostic difference between Cryptorchestia (sensu Lowry, 2013 and Orchestia. However, among the six northeast Atlantic island Cryptorchestia species only C. stocki has a small lobe on the merus of gnathopod 1. Reduction or loss of the lobe in the Atlantic Island species cannot be ruled out; however, molecular phylogenetic analysis leads us to presume that this lobe independently evolved between the east Mediterranean Cryptorchestia species and C. stocki from Gran Canaria.

    Whale Habitat and Prey Studies were conducted off southern California during August 1995 (WHAPS95) and July 1996 (WHAPS96) to (1) study the distribution and activities of blue whales and other large whales, (2) survey the distribution of prey organisms (krill), and (3) measure physical and biological habitat variables that influence the distribution of whales and prey. A total of 1307 cetacean sightings included 460 blue whale, 78 fin whale and 101 humpback whale sightings. Most blue whales were found in cold, well-mixed and productive water that had upwelled along the coast north of Point Conception and then advected south. They were aggregated in this water near San Miguel and Santa Rosa Islands, where they fed on dense, subsurface layers of euphausiids both on the shelf and extending off the shelf edge. Two species of euphausiids were consumed by blue whales, Thysanoessa spinifera and Euphausia pacifica, with evidence of preference for the former, a larger and more coastal species. These krill patches on the Channel Island feeding grounds are a resource exploited during summer-fall by the world's largest stock of blue whales.

  14. Radon progeny monitoring at the Eastern North Atlantic (ENA), Graciosa Island ARM facility and a potential earthquake precursory signal

    Radon has been considered a promising earthquake precursor, the main rationale being an expected increase in radon exhalation in soil and rocks due to stress associated with the preparatory stages of an earthquake. However, the precursory nature of radon is far from being convincingly demonstrated so far. A major hindrance is the many meteorological and geophysical factors diving radon temporal variability, including the geophysical parameters influencing its emanation (grain size, moisture content, temperature), as well as the meteorological factors (atmospheric pressure, moisture, temperature, winds) influencing its mobility. Despite the challenges, radon remains one of the strongest candidates as a potential earthquake precursor, and it is of crucial importance to investigate the many factors driving its variability and its potential association with seismic events. Continuous monitoring of radon progeny is performed at the Eastern North Atlantic (ENA) facility located in the Graciosa island (Azores, 39N; 28W), a fixed site of the Atmospheric Radiation Measurement programme (ARM), established and supported by the Department of Energy (DOE) of the United States of America with the collaboration of the local government and University of the Azores. The Azores archipelago is associated with a complex geodynamic setting on the Azores triple junction where the American, Eurasian and African litospheric plates meet, resulting in significant seismic and volcanic activity. A considerable advantage of the monitoring site is the availability of a comprehensive dataset of concurrent meteorological observations performed at the ENA facility and freely available from the ARM data archive, enabling a detailed analysis of the environmental factors influencing the temporal variability of radon's progeny. Gamma radiation is being measured continuously every 15 minutes since May 2015. The time series of gamma radiation counts is dominated by sharp peaks lasting a few hours and

  4. Arctic ice islands

    The development of offshore oil and gas resources in the Arctic waters of Alaska requires offshore structures which successfully resist the lateral forces due to moving, drifting ice. Ice islands are floating, a tabular icebergs, up to 60 meters thick, of solid ice throughout their thickness. The ice islands are thus regarded as the strongest ice features in the Arctic; fixed offshore structures which can directly withstand the impact of ice islands are possible but in some locations may be so expensive as to make oilfield development uneconomic. The resolution of the ice island problem requires two research steps: (1) calculation of the probability of interaction between an ice island and an offshore structure in a given region; and (2) if the probability if sufficiently large, then the study of possible interactions between ice island and structure, to discover mitigative measures to deal with the moving ice island. The ice island research conducted during the 1983-1988 interval, which is summarized in this report, was concerned with the first step. Monte Carlo simulations of ice island generation and movement suggest that ice island lifetimes range from 0 to 70 years, and that 85% of the lifetimes are less then 35 years. The simulation shows a mean value of 18 ice islands present at any time in the Arctic Ocean, with a 90% probability of less than 30 ice islands. At this time, approximately 34 ice islands are known, from observations, to exist in the Arctic Ocean, not including the 10-meter thick class of ice islands. Return interval plots from the simulation show that coastal zones of the Beaufort and Chukchi Seas, already leased for oil development, have ice island recurrences of 10 to 100 years. This implies that the ice island hazard must be considered thoroughly, and appropriate safety measures adopted, when offshore oil production plans are formulated for the Alaskan Arctic offshore. 132 refs., 161 figs., 17 tabs.

    One source of uncertainty that thwarts accurate and comprehensive representation of the present and future climate in models is the response of shallow cloud systems to changes in atmospheric greenhouse gases and aerosols. Low clouds systems that prevail over subtropical oceans, in particular, play a critical role in boundary layer dynamics and in the global climate, despite being poorly represented in climate models. The Azores have been identified as an optimal site to conduct research aimed at better understanding the physical processes and life cycle of marine stratocumulus and other marine boundary layer clouds. The United States Department of Energy's Atmospheric Radiation Measurement (ARM) Climate Research Program has been providing data to advance research from atmospheric observations at diverse climatic regimes around the world (http://www.arm.gov/) for over 20 years. Since 2009, the Azores has been included in this global program. The campaign of the ARM Mobile Facility at Graciosa Island, Azores, in the context of the Clouds, Aerosol and Precipitation in the Marine Boundary Layer (CAP-MBL) project, added the most extensive and comprehensive dataset of marine boundary layer (MBL) clouds to date. Solid preliminary findings from this valuable data set have been used to understand interactions between the cloud microphysical and macrophysical processes in marine boundary layer clouds that play a fundamental role in the cloud dynamics and precipitation, which in turn determine cloud radiative properties that impact on the energy balance of the Earth. Based upon the design and siting from the previous ARM Mobile Facility in support of CAP-MBL, the new Eastern North Atlantic (ENA) fixed site joined the global network of ARM Climate Research Facilities in October 2013. Since then, this user facility has augmented its baseline measurement capability to include a Ka-/W-Band scanning cloud radar, an X-Band precipitation radar and Raman and Doppler lidars. Coupled

    The plate boundary at the eastern terminus of the Azores-Gibraltar transform fault between Africa and Iberia is poorly defined. The deformation in the area is forced by the slow NW-SE convergence of 4 mm/yr between the oceanic domains of Iberia/Eurasia and Africa and is accommodated over a 200 km broad tectonically-active deformation zone. The region, however, is also characterized by large earthquakes, such as the 1969 Mw=7.9 Horseshoe event and the November 1, 1755 Great Lisbon earthquake with an estimated magnitude of Mw~8.5. The exact location of the source of the 1755 Lisbon earthquake is still unknown. Recent work may suggest that the event occurred in the vicinity of the Horseshoe fault, an oblique thrust fault. However, estimates of tsunami arrival times suggested a source near the Gorringe Bank, a ~180 km-long and ~70 km-wide ridge that has a relieve of ~5000 m. Deep Sea Drilling (DSDP) and rock samples indicated that the bank is mainly composed of serpentinized peridotites with gabbroic intrusions, perhaps being created by overthrusting of the Horseshoe Abyssal Plain onto the Tagus Abyssal Plain in NW direction. Further, the Horseshoe Abyssal Plain is marked by the presence of compressive structures with a roughly NE-SW orientation and E-W trending, segmented, crustal-scale, strike slip faults that extend from the Gorringe Bank to the Gibraltar Arc in the eastern Gulf of Cadiz, which were called "South West Iberian Margin" or SWIM faults. The fault system may mark a developing Eurasia-Africa plate boundary. Two local seismic networks were operated in the area. First, a network of 14 ocean-bottom seismometers (OBS) was operated between April and October 2012 in the vicinity of the Horseshoe fault between 10°W to 11°W, and 35°50'N to 36°10'N. From October 2013 to March 2014 a second network of 15 OBS monitored seismicity at the Gorringe Bank. Both networks benefitted from seismic stations operated in Portugal.

    In the sixteenth century there were great advances in science, literature, and the arts. During this century, urology as a specialty was conceived, thanks to the contributions of Andreas Vesalius, anatomist and leading physician to the court of Charles V, and Dr. Francisco Diaz, a native of Alcala de Henares, surgeon and clinician. Dr. Diaz had a close relationship with Miguel de Cervantes, who at one point in his life suffered from renal colic. In his masterpiece "Re-Printed Treaty of all diseases of the kidneys, bladder and wattles of the Cock and Urina, divided into three books," of which the first book of urology is the History of Medicine, describes in detail the clinical and therapeutic aspects of urological diseases, known as the "bad stone" and urethral strictures known as "wattles", in addition to describing the different surgical techniques and the development of new instruments for urological procedures, which include the cisorio instrument and the Speculum pudendi. For the above, Dr. Francisco Diaz is considered the father of urology.

Taking into account that the cultural tourism is an agent of development, this article deals with the trajectory of the Guarani Mbya community from 1988 to 2003 in the county of São Miguel das Missões, in the state of Rio Grande do Sul, where the touristic attraction is the “Jesuitic Ruins of Saint Michael of the Missions”. The article tries to identify the benefits wich the community has had, due to the local touristic activity. It was confirmed that the Guarani, as a result of this activity, are now the owners of the land and that their permanence in the Inhacapetum reserve is a way of showing the development factor in this analized period of time and the role that touristic activity has had in their lives. Even though the State of Rio Grande do Sul has claimed it is the responsible for all this accomplishment, this isn’t confirmed. Citizens related to the local government where the indian settlement is located, are main responsibles for the benefits reached by the Guarani community.

Como instrumentos son útiles según el conservadurismo ultramontano de este intelectual patricio para homogeneizar, uniformar y contrarrestar la pluralidad de las sociedades. El orden de la sociedad está por encima de cualquier demanda por la libertad, y por ello al potenciar la contienda ideológica y aumentar la intolerancia se genera una sociedad en abierta lucha contra la disidencia, la confrontación y la controversia, de modo, que la opción de la oposición política como garantía del reconocimiento de los derechos de las minorías y de las opiniones diversas debe ser aniquilada, censurada y, por supuesto, extirpada.

    Full Text Available Contemporary spanish poetry tends to be divided into two big groups: “seventies'poetry” or “Novísima” and “Poetry of experience”. This clasification is due not only to some generalizing studies promoted by the institution, but also to the desire of the poets to create a group in which they can be attached to and in which they are able to differ from the feared “other”. Such dual caracterization has prompted numerous debates over the belonging and appropriateness of those categories, wich remain in the perspectives that are used to approach the phenomenon now a days. In this way, the aesthetic proposal of the poet José-Miguel Ullán, traditionally considered as a member of the generation known as the seventies, can be taken as an example of an author that can't be clasified in any of the mentioned groups, and because of it, as a starting point for a possible revision and dismountage of a history that has been partially told: the history of spanish contemporary poetry.

    2007-01-01

    Full Text Available Los varones tienden a omitir o minimizar los daños causados por el trabajo, pues, como hombres, los consideran una naturalización de su desempeño laboral, y, por tanto, asocian la manera masculina de conducirse con ideas de mayor fortaleza e invulnerabilidad ante los riesgos y padecimientos laborales. El presente artículo explora las vivencias de los jornaleros agrícolas del poblado Miguel Alemán (PMA, en Sonora, en los procesos de salud-enfermedad y la construcción social de la masculinidad dominante. El objetivo principal es documentar las prácticas de autoatención y autocuidado de los varones de la región y los costos para la salud en un contexto de orden de género. Después de revisar los postulados teóricos utilizados, se analizan casos de accidentes de trabajo (como la intoxicación por el agroquímico cianamida hidrogenada, las hemorroides y el efecto de la relación entre la idea de una inmunidad subjetiva (IS y la identidad masculina, frente a la enfermedad y el peligro. El artículo permite acercarse a los procesos microsociales con enlaces empírico-metodológicos de los ámbitos laboral y doméstico, y describe etnográficamente prácticas y discursos de los actores y actrices.

    2013-07-01

    Full Text Available Tanto la arquitectura tradicional japonesa como los pensamientos del filósofo chino Lao zi son referencias fundamentales en la obra de Miguel Fisac, uno de los arquitectos españoles más destacados de la segunda mitad del siglo XX. A pesar de haber reconocido estas influencias en numerosas ocasiones, este hecho todavía no ha sido objeto de un estudio profundo. Sin embargo, el análisis de su obra y de su interés por Japón, a donde viajó varias veces, pone de relieve que la arquitectura española fue permeable a este influjo. El presente artículo aporta una visión más completa de la evolución de Fisac y ofrece un panorama histórico de su desarrollo durante las décadas de los años cuarenta y cincuenta, cuando concibió su personal concepto de la arquitectura tomando ideas de diferentes fuentes, entre las que Oriente se encuentra en un lugar principal. Además, se examina en detalle la repercusión que el contacto con la arquitectura japonesa tuvo en su producción.

  20. A Phenomenology of Islands

    Directory of Open Access Journals (Sweden)

    2006-05-01

    Full Text Available The question is posed: is a coherent theory of islandness – nissology – possible? Faultlines within constructions of islands and islandness are noted. Some of these axes of contestation have remained latent but have the potential to be sharply divisive. Three of the identified faultlines are examined – the nature of the island ‘edge’, the import for questions of island memory and identity of massive inward and outward movements of people, and the appropriation of island ‘realness’ by those for whom ‘island’ best functions as metaphor. A case is made for the excision of the latter from the purview of island studies. Despite apparent irreconcilability within island studies’ emerging faultlines, it is argued that place theory does constitute a theoretical framing that can work for island studies. Following a brief overview of the faultlines that also exist within place studies, it is noted that the difference-respecting and identity focused nature of phenomenology of place is particularly apposite for island studies, and the paper concludes with a consideration of what a phenomenology of islands might look like.

  3. Paradise Islands? Island States and Environmental Performance

    Full Text Available Island states have been shown to outperform continental states on a number of large-scale coordination-related outcomes, such as levels of democracy and institutional quality. The argument developed and tested in this article contends that the same kind of logic may apply to islands’ environmental performance, too. However, the empirical analysis shows mixed results. Among the 105 environmental outcomes that we analyzed, being an island only has a positive impact on 20 of them. For example, island states tend to outcompete continental states with respect to several indicators related to water quality but not in aspects related to biodiversity, protected areas, or environmental regulations. In addition, the causal factors previously suggested to make islands outperform continental states in terms of coordination have weak explanatory power in predicting islands’ environmental performance. We conclude the paper by discussing how these interesting findings can be further explored.

  4. Electrochemical island growth

    Science.gov (United States)

    Guo, Lian

    The ability to independently dictate the shape and crystal orientation of islands in electrocrystallization remains a significant challenge. The main reason for this is that the complex interplay between the substrate, nucleation, and surface chemistry are not fully understood. Here the kinetics of 3D island growth for copper on ruthenium oxide is studied. The small nucleation overpotential leads to enhanced lateral growth and the formation of hexagonal, disk-shaped islands. The amorphous substrate allows the nuclei to achieve the thermodynamically favorable orientation, i.e. a surface normal. Island growth follows power law kinetics in both lateral and vertical directions. At shorter times, the two growth exponents are equal to 1/2 whereas at longer times lateral growth slows down while vertical growth speeds up. Accordingly, a growth mechanism is proposed, wherein the lateral growth of disk-shaped islands is initiated by attachment of Cu adatoms on the ruthenium oxide surface onto the island periphery while vertical growth is initiated by 2D nucleation on the top terrace and followed by lateral step propagation. These results indicate three criteria for enhanced lateral growth in electrodeposition: (i) a substrate that leads to a small nucleation overpotential, (ii) fast adatom surface diffusion on substrate to promote lateral growth, and (iii) preferential anion adsorption to stabilize the basal plane. The surface roughness evolution, during isolated island growth, island coalescence, and continuous film growth, has also been studied as a function of island shape and island density. It is shown that the surface width wsat(l,t) initially follows anomalous scaling in the isolated island growth regime but exhibits normal scaling during the early stages of continuous film growth. Furthermore, the short length scale roughness is dependent primarily on island shape while the long length scale roughness is dependent on island density. Electrochemical deposition of

    Full Text Available ABSTRACT: The seventh novel written by Miguel Delibes, "La hoja roja" (1959 is branded by a recognizable individual style in which is found a double compromise that can’t be easily separated: human –preoccupied with the creation of voracious and intimate characters– and geographical –by utilizing his native Castile, both urban and rural, as the setting for his stories. With the objective of achieving the highest degree of credibility regarding the characters of his novels, Delibes makes use of various narrative techniques, among which it is important to mention one in particular: the fact that his characters have memories. This characteristic, together with the description of with the practices of their everyday lives, contributes to create individuals with a personal past as well as a present where interaction with the rest of the characters results crucial. Paradoxically, within the numerous and varied critical approaches to Delibes’ work, the topic of memory has never been considered as the central element in the investigation, although there are instances in which it is obliquely mentioned. Through these particular stories, that interweave the lives of the principal and secondary characters, Delibes recovers a collective memory as he narrates the present. In the author’s particular vision one can read the direct relationship between solitude and death as a warning on the precarious condition in human relationships in Spain’s society in the fifties, where the main pathology is solitude.. RESUMEN: Séptima novela escrita por Miguel Delibes, "La hoja roja" (1959 está marcada por un reconocido estilo propio donde se puede distinguir un doble compromiso de difícil separación: humano –preocupado por crear personajes veraces y entrañables– y geográfico –que utiliza su Castilla natal, la rural y la urbana, como escenario de sus historias–.

    Full Text Available The study was carried out in the eastern plains from June to September 1999. The material wascollected in Villavicencio and San Miguel (Meta - Colombia. A total of 315 birds representing74 species of 23 families were examined for haematozoa. 50 birds harboured blood parasites.These included: Microfilariae(8.25%; Haemoproteus(6.67%; Plasmodiumand Trypanosoma(0.95% and Hepatozoon(0.32%. The prevalence of infection is this sample is low in comparisonto that recorded for Neartic birds as reported by Greiner et al.

The most striking aspect ofthis survey, is the high prevalence of Microfilariaecompared to that recorded elsewhere in theworld, almost 50% of the total infection. We hypothesize that microfilariaeare transmitted bya vector that is not utilized by either the haemoproteids or the plasmodiids. Finally 8 specieswere examined for blood parasites for the first time, 15 new host-parasite records for the worldand 15 new for Colombia were established from this sample. This survey and other similarstudies, clearly indicate that research on this topic is urgently required, particularly since thereare direct correlations between stress (e.g. from habitat destruction and pathogenicity ofhaematozoa to their bird hosts.El estudio se llevó a cabo en los llanos orientales de junio a septiembre de 1999.

    In this work was used the technique of Neutron Activation Analysis to characterize obsidian samples and of archaeological ceramic coming from the archaeological site of San Miguel Ixtapan, Estado de Mexico; and samples of clay of three banks bordering to the site. The characterization of the ceramic, was complemented with the analysis of pastes (cooked clay) and pigments, with the techniques of X ray diffraction (XRD) and Scanning Electron Microscopy (SEM). With the technique of NAA was determined the concentration of 13 elements (Eu,Ce,Lu, Yb, U, Th, Sb, Cs, Sc, Rb, Fe, Co and La) in 44 obsidian samples, in some of them were also determined Na, K and Mn. The analysis of the data, with different techniques of multivariable analysis, indicated that the obsidian comes from three locations that are: Sierra de las Navajas in the Estado de Hidalgo, Zinaparo and Zinapecuaro, both located in the Estado de Michoacan. On the other hand, in the ceramic samples and local clay 19 elements were measured (Sm, Nd, Ce, Lu, Eu, Yb, U, Th, Tb, Cr, Hf, As, Sb, Cs, Sc, Rb, Fe, Co and La). The statistical analysis of the data revealed differences in the elementary composition of the samples, being three main groups that in accordance with the archaeological classification they correspond to the ceramic types: local, foreign and regional. By means of the determination of the elementary composition of the local clays was possible to identify the local ceramic. These results are confirmed with those of the study of XRD, in the one which were observed differences in the mineralogical composition among these three groups. (Author)

    The seismicity of the South Atlantic Ocean has been recorded by the MARCHE network of 4 autonomous underwater hydrophones (AUH) moored within the SOFAR channel on the flanks of the Mid-Atlantic Ridge (MAR). The instruments were deployed south of the Azores Plateau between 32° and 39°N from July 2005 to August 2008. The low attenuation properties of the SOFAR channel for earthquake T-wave propagation result in a detection threshold reduction from a magnitude completeness level (Mc) of ~4.3 for MAR events recorded by the land-based seismic networks to Mc=2.1 using this hydrophone array. A spatio-temporal analysis has been performed among the 5600 events recorded inside the MARCHE array. Most events are distributed along the ridge between lat. 39°N on the Azores Platform and the Rainbow (36°N) segment. In the hydrophone catalogue, acoustic magnitude (Source Level, SL) is used as a measure of earthquake size. The source level above which the data set is complete is SLc=205 dB. We look for seismic swarms using the cluster software of the SEISAN package. The criterion used are a minimum SL of 210 to detect a possible mainshock, and a radius of 30 km and a time window of 40 days after this mainshock (Cevatoglu, 2010, Goslin et al., 2012). 7 swarms with more than 15 events are identified using this approach between 32°et 39°N of latitude. The maximum number of earthquake in a swarm is 57 events. This result differs from the study of Simao et al. (2010) as we processed a further year of data and selected sequences with fewer events. Looking at the distribution of the SL as a function of time after the mainshock, we discuss the possible mechanism of these earthquakes : tectonic events with a "mainshock-aftershock" distribution fitting a modified Omori law or volcanic events showing more constant SL values. We also present the geophysical setting of these 7 swarms, using gravity, bathymetry, and available local geological data. This study illustrates the potential of

    Satellite altimetry has been widely used to study the variability of the ocean currents such as the Azores Current (AzC) in the North Atlantic. Most analyses are performed over the region that encloses the current, thus being somehow affected by other oceanographic signals, e.g., eddies. In this study, a new approach for extracting the axis of a zonal current solely based on satellite altimetry is presented. This is a semi-automatic procedure that searches for the maximum values of the gradient of absolute dynamic topography (ADT), using the geostrophic velocity as auxiliary information. The advantage of this approach is to allow the analyses to be performed over a buffer centered on the current axis instead of using a wider region. It is here applied to the AzC for the period June 1995-October 2006.

    Una vez más, en este Claustro Venerable, se me concede honor superior a mis cortos merecimientos al otorgarme la palabra para celebrar uno de los muchos hitos que resplandecen en los casi cuatro siglos de historia que han transcurrido desde el glorioso momento en que Fray Cristóbal de Torres dio vida legal e inmarcesible impulso a nuestro Colegio Mayor.
    Hoy tengo el encargo de evocar la figura ascética de quien fuera mano derecha del Sabio José Celestino Mutis en el establecimiento de los estudios médicos, el galeno Don Miguel de Isla, doscientos años exactos después de ese dos de Octubre de 1801 en que la Real Cédula de Carlos IV le permitió llegar a la cátedra y abrir así, formal y estable, la escuela que graduaría los primeros médicos de la Nueva Granada.

  12. The transition from linear to diffuse plate boundary in the Azores-Gibraltar region: results from a thin-sheet model

    We use the thin-sheet plane-stress approach to study the present-day dynamic behavior of the plate boundary between Eurasia and Africa along the Azores-Gibraltar region. This plate boundary, which extends from the Azores triple junction to the Gibraltar strait, shows a tectonic regime that changes from transtension in the west to transpression in the east, with a strike-slip motion in its central segment. Seismological data reveal that the western and central segments are currently marked by a linear series of earthquakes indicating that the plate boundary is located in a narrow zone. In contrast, the eastern segment is not so well defined and deformation spreads over a much broader area. To apply the thin-sheet approach, we combined heat flow, elevation and crustal thickness data to calculate the steady-state geotherm and the total strength of the lithosphere. Several models with different fault friction coefficients and geometries at the eastern segment of the plate boundary were tested. Results are compared with the maximum compressive stress directions from the World Stress Map, and the calculated seismic strain rates and slip vectors from earthquake data. The best fitting models are consistent with the rotation pole of Argus et al. [D.F. Argus et al., J. Geophys. Res. 94 (1989) 5585-5602], and show that the rheological behavior of the plate boundary must necessarily change from the western and central segments to the eastern segment. The diffuse character of the plate boundary east of the Gorringe Bank is dominated by the transition from oceanic to continental lithosphere, the weakness of the Alboran domain, and the convergence between the African and the Eurasian plates. The displacement of the Alboran domain relative to the African plate may play a major role in stress propagation through the Iberian Peninsula and its Atlantic margin.

    Tea is the second most commonly consumed beverage in the world. It is well recognized that the consumption of tea in high quantities can promote the development of fluorosis. The main objective of this study is to estimate the exposure to fluoride in the Azores through drinking tea prepared with water from different volcanic locations, by i) investigating the fluoride (F) content of various commercial brands of tea (Camellia sinensis) marketed in Azores and ii) comparing tea releasing rates of F according to brewing time, considering the fluoride concentration in the different types of water used for the infusion. Fluoride contents were determined by ion-selective electrode in 30 samples of drinking water from three different locations and in 450 samples of tea (black and green tea) from three different brands. Fluoride concentration in water ranged from 0.29 to 1.56 ppm (Porto Formoso and Sete Cidades village, respectively). Fluoride concentrations increased with brewing time, reaching the highest values in the Azorean black and green tea infusions. For all the studied brands, a negative correlation was found between tea fluoride contents and the pH of the water used to prepare the infusion. Fluoride concentration in infusions was significantly associated with the background fluoride concentration in drinking water. Since the fluoride concentration in groundwater varies accordingly to the geological conditions and tea consumption can contribute to fluoride intake, it is important to define the limits for tea consumption, particularly in fluoride-rich areas. Graphical Abstract Fluoride concentrations in black and green tea for 3 minutes of brewing time and, association between fluoride concentration and pH with brewing time.

  15. Imaging active faulting in a region of distributed deformation from the joint clustering of focal mechanisms and hypocentres: Application to the Azores-western Mediterranean region

    The matching between linear trends of hypocentres and fault planes indicated by focal mechanisms (FMs) is frequently used to infer the location and geometry of active faults. This practice works well in regions of fast lithospheric deformation, where earthquake patterns are clear and major structures accommodate the bulk of deformation, but typically fails in regions of slow and distributed deformation. We present a new joint FM and hypocentre cluster algorithm that is able to detect systematically the consistency between hypocentre lineations and FMs, even in regions of distributed deformation. We apply the method to the Azores-western Mediterranean region, with particular emphasis on western Iberia. The analysis relies on a compilation of hypocentres and FMs taken from regional and global earthquake catalogues, academic theses and technical reports, complemented by new FMs for western Iberia. The joint clustering algorithm images both well-known and new seismo-tectonic features. The Azores triple junction is characterised by FMs with vertical pressure (P) axes, in good agreement with the divergent setting, and the Iberian domain is characterised by NW-SE oriented P axes, indicating a response of the lithosphere to the ongoing oblique convergence between Nubia and Eurasia. Several earthquakes remain unclustered in the western Mediterranean domain, which may indicate a response to local stresses. The major regions of consistent faulting that we identify are the mid-Atlantic ridge, the Terceira rift, the Trans-Alboran shear zone and the north coast of Algeria. In addition, other smaller earthquake clusters present a good match between epicentre lineations and FM fault planes. These clusters may signal single active faults or wide zones of distributed but consistent faulting. Mainland Portugal is dominated by strike-slip earthquakes with fault planes coincident with the predominant NNE-SSW and WNW-ESE oriented earthquake lineations. Clusters offshore SW Iberia are

  17. Diagenesis of tetrapyrrole pigments at Site 467 Leg 63 San Miguel Gap (offshore California): A detailed study

    1991-01-01

    Sediments from DSDP Leg 63, Site 467 (San Miguel Gap, offshore California, USA) offer an unusual opportunity to study and quantify the distributional changes in tetrapyrrole pigment composition with burial depth. The samples available included an immature, wet and unconsolidated sample containing functionalised chlorins, to those approaching the onset of generation. The tetrapyrrole pigments have been quantified by UV/vis spectroscopy, while EIMS and HPLC were used to investigate the distributional changes. During this study a number of pigment types were encountered: (i) chlorins, (ii) free base alkyl and acid porphyrins, (iii) copper, nickel and vanadyl alkyl porphyrins, as well as their acid counterparts. Copper and vanadyl carboxylic acid porphyrins are reported for the first time in DSDP/IPOD sediments. Individual components have been examined by EIMS and HPLC coinjection with standards, as appropriate. During this study, free base C[sub 32] DPEP and C[sub 33] DPE, copper and nickel alkyl and acid porphyrins occurred in a wet and unconsolidated Upper Pliocene sediment (Section 18-5). Such a suite of porphyrins demonstrates that aromatisation, reduction of the C-13[sup 1] keto moiety present in all chlorophylls, decarboxylation and chelation can occur at a very early stage of diagenesis. The importance of thermal mechanisms occurring on components surviving early diagenesis is discussed in light of the findings herein. Copper alkyl porphyrins previously ascribed to an allochthonous source are now considered, along with porphyrin acid counterparts, as autochtonous components. The behaviour of Cu(II), Ni(II) and VO(II) species under differing redox conditions is discussed in relation to pigment preservation and the porphyrin distributions associated with these chelates. A C[sub 31] 15-17 ethanoporphyrin was tentatively assigned in all samples, indicated a chlorophyll c input to the sediments. A source, at least in part, from dinoflagellates is considered.

    Detailed geologic surveys and different microscopic and analytical techniques were conducted near Tierra Blanca de Abajo where lung cancer and malignant mesothelioma (MM) are the primary causes of death. Results show that erionite-K occurs as a diagenetic product in altered Oligocene-Miocene rhyolitic tuffs. The microscopic structure of erionite minerals shows concentrations of individual fibers in the range of 0.14-0.547 μm in diameter and 2.81-50 μm in length, with a few "bundles" about 0.2-2.5 μm wide by 10-50 μm long. Chemical properties of erionite show Si/Al in the range of 3.23-3.58 (at.%) and T Si in the range of 0.76-0.78 (at.%). Potassium is the dominant cation (K > Ca > Mg > Fe). Associated minerals are heulandite, clinoptilolite, quartz, sanidine, anorthite, smectite and opal. This mineral assemblage formed in the lower part of an open catchment, where bicarbonate-rich (T > 30 °C, pH > 8) groundwater discharge conditions prevailed in the past. The physical and chemical characteristics of erionite near San Miguel de Allende are similar to those of erionite from the Cappadocian region of Turkey where erionite is associated with MM. The presence of erionite and the type of respiratory diseases that occur in the village strongly suggest the need for detailed health-based studies in the region. Pliocene-Holocene fine-grain deposits, used in the past for the construction of adobe-houses and exposed in recreational areas, also contain erionite associated with erosion and alluvial transport from the rhyolitic tuffs, potentially affecting more than 13 villages located downstream toward the Allende Dam.

    The Jesuit Missions the Guaranis were one of the great examples of cultural, social, and scientific of the eighteenth century, which had its decline from successive wars that followed the exchange of territories domain occupied by Portugal and Spain with the Madrid Treaty of January 13, 1750. One of the great examples of this development is materialized in the ruins of 30 churches and villages that remain in a territory that now comprises part of Brazil, Argentina and Paraguay. These Churches, São Miguel das Missões is among the Brazilian ruins, the best preserved. The ruins of São Miguel das Missões were declared a UNESCO World Cultural Heritage in 1983 and the Institute of National Historical Heritage (IPHAN) is the Brazilian Federal agency that manages and maintains this heritage. In order to produce a geographic database to assist the IPHAN in the management of the Ruins of São Miguel das Missões it was proposed a three-dimensional mapping of these ruins never performed in this location before. The proposal is integrated data acquired from multiple sensors: two micro-UAV, an Asctec Falcon 8 (rotary wing) and a Sensefly e-Bee (fixed wing); photos from terrestrial cameras; two terrestrial LIDAR sensors, one Faro Focus 3D S-120 and Optec 3D-HD ILRIS. With this abundance of sensors has been possible to perform comparisons and integration of the acquired data, and produce a 3D reconstruction of the church with high completeness and accuracy (better than 25 mm), as can be seen in the presentation of this work.

    2015-04-01

    Full Text Available An approach to Miguel Angel Bustos's poetry requires a methodological reexamination that does not sever its semantic flow. A poetry that seeks deep and heightened sense and that conceives its word as verb of divine origin cannot be analyzed without the understanding of the prefigured transcendence of its genesis. Attending to this predicament, we observe that the ricoeurian hermeneutics provides us with a consonant tool which forges a bond between word and existence. In Vision de los hijos del mal, Ricoeur's concepts of symbol and myth allow an access to the close relation among the experience of evil, language and sense.

  13. Floating sandstones off El Hierro (Canary Islands, Spain: the peculiar case of the October 2011 eruption

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available The eruption that started off the south coast of El Hierro, Canary Islands, in October 2011 has emitted intriguing eruption products found floating in the sea. These specimens appeared as floating volcanic "bombs" that have in the meantime been termed "restingolites" (after the close-by village of La Restinga and exhibit cores of white and porous pumice-like material. Currently the nature and origin of these "floating stones" is vigorously debated among researchers, with important implications for the interpretation of the hazard potential of the ongoing eruption. The "restingolites" have been proposed to be either (i juvenile high-silica magma (e.g. rhyolite, (ii remelted magmatic material (trachyte, (iii altered volcanic rock, or (iv reheated hyaloclastites or zeolite from the submarine slopes of El Hierro. Here, we provide evidence that supports yet a different conclusion. We have collected and analysed the structure and composition of samples and compared the results to previous work on similar rocks found in the archipelago. Based on their high silica content, the lack of igneous trace element signatures, and the presence of remnant quartz crystals, jasper fragments and carbonate relicts, we conclude that "restingolites" are in fact xenoliths from pre-island sedimentary rocks that were picked up and heated by the ascending magma causing them to partially melt and vesiculate. They hence represent messengers from depth that help us to understand the interaction between ascending magma and crustal lithologies in the Canary Islands as well as in similar Atlantic islands that rest on sediment/covered ocean crust (e.g. Cape Verdes, Azores. The occurrence of these "restingolites" does therefore not indicate the presence of an explosive high-silica magma that is involved in the ongoing eruption.

    Goslin, J.; Bazin, S.; Dziak, R. P.; Fox, C.; Fowler, M.; Haxel, J.; Lourenco, N.; Luis, J.; Martin, C.; Matsumoto, H.; Perrot, J.; Royer, J.

    2004-12-01

    The seismicity of the North Atlantic was recorded by two networks of hydrophones moored in the SOFAR channel, north and south of the Azores Plateau. The interpretation of the hydro-acoustic signals recorded during the first six-month common period of operation of the two networks (June 2002 to Nov. 2002) provides a unique data set on the spatial and time distributions of the numerous low-magnitude earthquakes which occurred along the Mid-Atlantic Ridge. Close to 2000 events were localized during this six-month period between latitudes 15° N and 63° N, 501 of which are localized within the SIRENA network (40° N-51° N) and 692 within the wider South Azores network (17° N-33° N). Using hydrophones to locate seafloor earthquakes by interpreting T-wave signals lowers the detection threshold of Mid-Atlantic Ridge events to 3.0 mb from the 4.7 mb of global seismic networks. This represents an average thirty-fold increase in the number of events: 62 events were detected by global seismological networks within the same area during the same period. An along-ridge spatial distribution of the seismicity is obtained by computing the cumulated numbers of events in 1° -wide latitudinal bins. When plotted vs. latitude, this first-order distribution shows remarkable long-wavelength patterns: the seismicity rate is low when approaching the Azores and Iceland (reaching values as low as 10 events/d° ), while it peaks to 70 events/d° in the vicinity of the Gibbs FZ. Moreover, the latitudinal distribution of the seismicity hints at an asymmetric influence of the Azores hotpot on the MAR. Finally, the spatial distribution of the seismicity anti-correlates well at long wavelengths with the zero-age depths along the MAR and correlates with the zero-age Mantle Bouguer (MBA) anomaly values and the Vs velocity anomalies at 100 km in the upper mantle. It is thus proposed that the seismicity level would be partly tied to the rheology and thickness of the brittle layer and be thus

    Full Text Available The Marine Strategy Framework Directive intends to adopt ecosystem-based management for resources, biodiversity and habitats that puts emphasis on maintaining the health of the ecosystem alongside appropriate human use of the marine environment, for the benefit of current and future generations. Within the overall framework of ecosystem-based management, ecosystem models are tools to evaluate and gain insights in ecosystem properties. The low data availability and complexity of modelling deep-water ecosystems has limited the application of ecosystem models to few deep-water ecosystems. Here, we aim to develop an ecosystem model for the deep-sea and open ocean in the Azores exclusive economic zone with the overarching objective of characterising the food-web and ecosystem structure of the ecosystem. An ecosystem model with 45 functional groups, including a detritus group, two primary producer groups, eight invertebrate groups, 29 fish groups, three marine mammal groups, a turtle and a seabird group was built. Overall data quality measured by the pedigree index was estimated to be higher than the mean value of all published models. Therefore, the model was built with source data of an overall reasonable quality, especially considering the normally low data availability for deep-sea ecosystems. The total biomass (excluding detritus of the modelled ecosystem for the whole area was calculated as 24.7 t km-². The mean trophic level for the total marine catch of the Azores was estimated to be 3.95, similar to the trophic level of the bathypelagic and medium-size pelagic fish. Trophic levels for the different functional groups were estimated to be similar to those obtained with stable isotopes and stomach contents analyses, with some exceptions on both ends of the trophic spectra. Omnivory indices were in general low, indicating prey speciation for the majority of the groups. Cephalopods, pelagic sharks and toothed whales were identified as groups with

  11. CIELO-A GIS integrated model for climatic and water balance simulation in islands environments

    Science.gov (United States)

    Azevedo, E. B.; Pereira, L. S.

    2003-04-01

    The model CIELO (acronym for "Clima Insular à Escala Local") is a physically based model that simulates the climatic variables in an island using data from a single synoptic reference meteorological station. The reference station "knows" its position in the orographic and dynamic regime context. The domain of computation is a GIS raster grid parameterised with a digital elevation model (DEM). The grid is oriented following the direction of the air masses circulation through a specific algorithm named rotational terrain model (RTM). The model consists of two main sub-models. One, relative to the advective component simulation, assumes the Foehn effect to reproduce the dynamic and thermodynamic processes occurring when an air mass moves through the island orographic obstacle. This makes possible to simulate the air temperature, air humidity, cloudiness and precipitation as influenced by the orography along the air displacement. The second concerns the radiative component as affected by the clouds of orographic origin and by the shadow produced by the relief. The initial state parameters are computed starting from the reference meteorological station across the DEM transept until the sea level at the windward side. Then, starting from the sea level, the model computes the local scale meteorological parameters according to the direction of the air displacement, which is adjusted with the RTM. The air pressure, temperature and humidity are directly calculated for each cell in the computational grid, while several algorithms are used to compute the cloudiness, net radiation, evapotranspiration, and precipitation. The model presented in this paper has been calibrated and validated using data from some meteorological stations and a larger number of rainfall stations located at various elevations in the Azores Islands.

    Full Text Available This investigation arose as a practical part of the PhD thesis: Fisac's "bones"; the search for the ideal piece. The thesis analyzes Miguel Fisac’s patented architectural inventions. An exhaustive analysis of his patents allows for the discovery of the evolution of Fisac’s work and the Spanish master’s thought processes. They crystallized in his last and still current patented system:"Poured Architecture". Fisac dies in 2006 without seeing a practical application for his last invention. This is the basis to the present work, whose aim is to develop Fisac’s patent in the field of low cost single-family housing. A real practical case was developed which served as testing ground to analyse the possibilities and limitations of the system. The methodology and conclusions allow us to visualize as a whole the evolution of Miguel Fisac's thought processes, whilst covering Spain’s most recent building tradition and its relationship with current reality.

    Investigación planteada como parte práctica de la tesis doctoral: Los “huesos” de Fisac; la búsqueda de la pieza ideal. La tesis analiza las patentes del arquitecto Miguel Fisac. Un análisis exhaustivo de estas experiencias permite descubrir la evolución de la obra y el pensamiento del arquitecto que termina por condensarse en su última patente aun vigente: “arquitectura vertida”. Fisac fallece en 2006 sin ver ejecutado su último invento y este hecho servirá de base al presente trabajo que tiene por objetivo desarrollar esta patente en el campo de la vivienda unifamiliar de bajo coste. Para ello se plantea un caso práctico real que servirá como campo de pruebas para analizar las posibilidades y limitaciones del sistema. Su metodología y conclusiones permiten ver en conjunto la evolución del pensamiento constructivo de Fisac y además establecer un recorrido por la tradición constructiva española más próxima y su relación con la realidad actual.

    En el marco de esa alargada fiesta patriótica, el gobierno financió filmes con temáticas nacionalistas. Uno de ellos es Hidalgo: la historia jamás contada (Antonio Serrano, 2010, que ofrece una perspectiva totalmente inusual de la vida del héroe insurgente Miguel Hidalgo y Costilla. El presente artículo propone la tesis de que filmes como éste fueron financiados con el ánimo de (reapreciar símbolos históricos ante la crisis de identidad, valores y seguridad nacional que aqueja al país. En el caso de Hidalgo… fue un intento por reimpulsar a un personaje mítico que ayudase a enaltecer nuevamente lo idealizadamente mexicano.

Our aim is, firstly, to show that the translator added to the original story some literary influences whose origins are to be found in the 17th-century precious movement in France. Secondly, it is our aim to show that, eventually and taking the contributions of Preciosity as a starting point, the author of Les deux Amantes uses Cervantes’s work to put forward more personal ideas on the defence of women’s freedom.

    Full Text Available Most of the damages that the brick walls of historical buildings show, have the origin in capillary humidity. The way to remove this capillary humidities, is frequently by the deflection of the freatic level. This method causes the desiccation of the soil where lays the foundation of the building, and when the soil is constituted of clays of high plasticity, it happens processes of retraction, that causes the differential settling of the foundation, affecting negatively to the structure of the building. To explain this fact, we describe the studies realized in the foundation of the church of San Miguel in Morón, Sevilla.

    Gran parte de los daños que sufren las fábricas de las edificaciones históricas, tienen su origen en las humedades de capilaridad. Una de las propuestas para eliminarlas es la desviación o modificación del nivel freático. Ello trae consigo la desecación del terreno de apoyo de la cimentación, al pasar de un estado saturado a otro de humedad natural En aquellos casos en los que los suelos de apoyo de la cimentación estén constituidos por arcillas de alta plasticidad se producirían procesos de retracción, cuya consecuencia podría ser la aparición de asientos diferenciales, que afectarían de forma negativa a la estructura. Para explicar este fenómeno se describe el estudio realizado en la iglesia de San Miguel de Morón de la Frontera (Sevilla.

    Full Text Available Friar-architects carried out important projects in the Valencia area. These monks, who combined architectural with spiritual labors, accomplished works in which they knew how to combine tradition with new architectural tendencies. The church of St. Michael Archangel of Burjassot by Friar Francisco de Santa Bárbara, provides the chance to study this constructive phenomenon in relation to its doorway and twin altarpieces at the crossing. Without doubt, these structures demonstrate the direct influence of the Jesuit Andrea Pozzo's treatise Perspectiva Pictorum et Architectorum (1693-1700, which had a broad repercussion in the Valencia region.

    La actividad de los frailes arquitectos en el medio valenciano fue muy destacada. Estos frailes, que compaginaban su labor arquitectónica con la espiritual, realizaron obras en las que supieron compaginar la tradición con la nueva arquitectura moderna. En este sentido, la iglesia de San Miguel Arcángel de Burjassot, de fray Francisco de Santa Bárbara, nos ofrece la posibilidad de estudiar todo este fenómeno constructivo en su portada y retablos gemelos del crucero. Sin duda, tanto la portada como los retablos de esta iglesia, nos hablan de la influencia directa que en ellos se puede apreciar de la obra Perspectiva Pictorum et Architectorum, del jesuíta Andrea Pozzo. Evidentemente, este influjo del tratado de Pozzo en San Miguel Arcángel de Burjassot es un ejemplo más de la gran repercusión que tuvo esta obra en el ámbito valenciano.

    Full Text Available A global review of islands and their connections with astronomy throughout history up to the contemporary times suggests eight compelling, distinct yet interlocking reasons why islands have been and remain so important to astronomy and astronomers. Islands constitute favourable locations for various types of astronomy-related activities: from tracking satellites and monitoring significant celestial events, to providing exceptional locations to jurisdictions with mandated dark and unpolluted skies. They appeal for their favourable longitude and (especially southern latitude, as well as for their disposition towards the conditions that the scientific community may expect in an ideal world: relatively clear viewing conditions from a secure, self-contained platform that is, however, endowed with connectivity.

    Full Text Available This article proposes a process framework for developing and managing visitor attractions (VA in small island developing states with Trinidad and Tobago, a two-island state in the Caribbean, as the case study. An extensive literature review was conducted, supported by field observations, individual depth interviews, and small and large focus group meetings. The process framework identified four sets of processes: national policy formulation and legislation; inventory, classification, evaluation, and ranking of VA; general operations management involving project management activities; and site specific activities of development, operations, and maintenance. The value of the framework lies in the fact that no similar framework applicable to small islands was covered in the literature and validation was obtained from a panel of experts and a cross section of tourism stakeholders in Tobago.

    Human leukocyte antigen (HLA)-A, HLA-B, and HLA-DRB1 polymorphisms were examined in Madeira Island populations. The data was obtained at high-resolution level, using sequence-based typing (SBT). The most frequent alleles at each loci were: A*020101 (24.6%), B*5101 (9.7%), B*440201 (9.2%), and DRB1*070101 (15.7%). The predominant three-loci haplotypes in Madeira were A*020101-B*510101-DRB1*130101 (2.7%) and A*010101-B*0801-DRB1*030101 (2.4%), previously found in north and central Portugal. The present study corroborates historical sources and other genetic studies that say Madeira were populated not only by Europeans, mostly Portuguese, but also sub-Saharan Africans due to slave trade. Comparison with other populations shows that Madeira experienced a stronger African influence due to slave trade than Portugal mainland and even the Azores archipelago. Despite this African genetic input, haplotype and allele frequencies were predominantly from European origin, mostly common to mainland Portugal.

    Astronomer priests or "skywatchers" on Easter Island lived in stone towers that were used as observatories and built stone markers in the periphery that indicated the heliacal rising of certain stars that served to indicate the arrival of marine birds, turtles, the offshore fishing season, and times for planting and harvest. Petroglyphs related to such sites depict outriggers, fishhooks, pelagic fish, and turtles and supposedly represented a star map. In this chapter, we analyze a set of such skywatchers dwellings, and stone markers located upon the North coast of Easter Island that have astronomic orientations, its related petroglyphs, and the relations between these directions with their yearly activities and their ritual calendar.

    Continuous monitoring of gamma radiation is often performed in nuclear facilities and industrial environments as a way to control the ambient radioactivity and give warning of potential accidents. However, gamma radiation is also ubiquitous in the natural environment. The main sources are i) cosmic radiation from space, including secondary radiation from the interaction with atoms in the atmosphere, ii) terrestrial sources from mineral grains in soils and rocks, particularly Potassium (K-40), Uranium (U-238) and Thorium (Th-232) and their decay products (e.g. Radium, Ra-226) , and iii) airborne Radon gas (Rn-222), which is the dominant source of natural environmental radioactivity. The temporal variability of this natural radiation background needs to be well understood and quantified in order to discriminate non-natural sources of radiation in the environment and artificial radionuclides contamination. To this end, continuous gamma radiation monitoring is being performed at the Eastern North Atlantic (ENA) facility located in the Graciosa island (Azores, 39N; 28W), a fixed site of the Atmospheric Radiation Measurement programme (ARM), established and supported by the Department of Energy (DOE) of the United States of America with the collaboration of the local government and University of the Azores. The site is unique for the study of the natural radioactivity background on one hand due to the remote oceanic geographical location, in the middle of the North Atlantic Ocean and clear of direct continental influence, and on the other hand because of the comprehensive dataset of atmospheric parameters that is available for enhancing the interpretation of the radiation measurements, as a result of the vast array of very detailed and high-quality atmospheric measurements performed at the ARM-ENA facility. Gamma radiation in the range 475 KeV to 3000 KeV is measured continuously with a 3" x 3" NaI(Tl) scintillator. The campaign started started in May 2015, with gamma

What is often discussed, sometimes angrily, is the exact nature of U.S. colonialism, the extent to which the Island has acquired certain “postcolonial” traits such as linguistic and cultural autonomy, and the possibility of waging an effective decolonization process. The issue of national identity in Puerto Rico is still contested as intensely as ever. What is new about current scholarly discussions is that many intellectuals, especially those who align themselves with postmodernism, are highly critical of nationalist discourses. Other debates focus on the appropriate approach to population movements between the Island and the U.S. mainland. For example, some outside observers insist that, technically speaking, the Puerto Rican exodus should be considered an internal, not international, migration, while others, including myself, refer to such a massive dispersal of people as transnational or diasporic.

    Objective. To determine the incidence of bone islands in leprosy patients. Design. X-rays of feet and hands of patients with Hansen`s disease (leprosy) were reviewed retrospectively. A second group of related age- and sex-matched patients who did not have Hansen`s disease was used for control purposes. Controls had undergone hand or foot X-rays during diagnosis of other pathologies. The patients with Hansen`s disease were compared with the control group, and were also analyzed as subgroups with different types of leprosy. The results were subjected to statistical analysis. Patients. Ninety patients with Hansen`s disease were randomly selected for this study. Patients who had had ulcers on hands or feet were excluded from the study. Results and conclusions. Bone islands were demonstrated in 20 patients with Hansen`s disease; no bone islands were observed in the controls. This was statistically significant (P<0.01). Bone islands were only seen in patients with lepromatous leprosy and borderline types but were not demonstrated in patients with tuberculoid leprosy. There was also a statistically significant relationship for a disease duration of 15 years or more. The cause of this raised incidence of enostosis in leprosy patients is not clear, but there may be a genetic predisposition in patients with leprosy, or it may be a side effect of leprosy, especially the lepromatous form.

    On December 12, 1992, at 5:30 A.M. GMT, an earthquake of magnitude Ms 7.5 struck the eastern region of Flores Island, Indonesia (Figure 1), a volcanic island located just at the transition between the Sunda and Banda Island arc systems. The local newspaper reported that 25-m high tsunamis struck the town of Maumere, causing substantial casualties and property damage. On December 16, television reports broadcast in Japan via satellite reported that 1000 people had been killed in Maumere and twothirds of the population of Babi Island had been swept away by the tsunamis.The current toll of the Flores earthquake is 2080 deaths and 2144 injuries, approximately 50% of which are attributed to the tsunamis. A tsunami survey plan was initiated within 3 days of the earthquake, and a cooperative international survey team was formed with four scientists from Indonesia, nine from Japan, three from the United States, one from the United Kingdom, and one from Korea.

    Full Text Available To understand the impact of the northwestern Azores Current Front (NW-AzC/AzF system on HCO3--and N2-fixation activities and unicellular diazotrophic cyanobacteria (UCYN distribution, we combined geochemical and biological approaches from the oligotrophic surface to upper mesopelagic waters. N2-fixation was observed to sustain 45-85% of the HCO3--fixation in the picoplanktonic fraction performing 47% of the total C-fixation at the deep chlorophyll maximum north and south of the AzF. N2-fixation rates as high as 10.9 μmol N m-3 d-1 and surface nitrate δ15N as low as 2.7‰ were found in the warm (18-24°C, most saline (36.5-37.0 and least productive waters south of the AzF, where UCYN were the least abundant. However, picoplanktonic UCYN abundances up to 55 cells mL-1 were found at 45-200m depths in the coolest nutrient-rich waters north of the AzF. In this area, N2-fixation rates up to 4.5 μmol N m-3 d-1 were detected, associated with depth-integrated H13CO3--fixation rates at least 50% higher than observed south of the AzF. The numerous eddies generated at the NW-AzC/AzF seem to enhance exchanges of plankton between water masses, as well as vertical and horizontal diapycnal diffusion of nutrients, whose increase probably enhances the growth of diazotrophs and the productivity of C-fixers.

    New absolute paleomagnetic intensity (PI) are investigated from 37 lava flows located at Tenerife and Gran Canaria (Canary Islands). They complete previously published directional results from the same flows and therefore allow to examine the time variations of the full geomagnetic vector. Twenty-eight flows are radiocarbon dated between 1706 AD and about 13 200 BC and one is historical. Eight other flows are not dated but they have stratigraphic links with the dated flows and archeomagnetic ages had been attributed to them based on their paleomagnetic directions. Various mineralogical analyses were conducted, giving access to the nature of the magnetic minerals and to their grain size. We performed the original Thellier and Thellier paleointensity (PI) experiments with a success rate of about 65% coupling this experiment with the strict set of selection criteria PICRIT-03. The mean PIs at the flow level are based on 3 to 12 independent PI determinations except for one site in which only one reliable determination could be obtained. The data indicate some variability in the local field intensity with a prominent PI peak centered around 600 BC and reaching 80 μT (VADM 16 ×1022 Am2), documented for the first time in this region. Combined with the published data obtained from western Africa, Spain, Portugal, Morocco and the Azores within a 2000 km-radius around the Canary Islands, our data allow to construct a curve illustrating the Earth magnetic field intensity fluctuations for Southwestern Europe/Western Africa. This curve, compared to the one produced for the Middle East and one calculated for Central Asia shows that maximum intensity patches have a very large geographical extent. They do not yet appear clearly in the models of variations of the dipolar field intensity.

    Santa Rosa Island (SRI) is the second-largest of the California Channel Islands. It is one of 4 east–west aligned islands forming the northern Channel Islands chain, and one of the 5 islands in Channel Islands National Park. The landforms, and collections of landforms called landscapes, of Santa Rosa Island have been created by tectonic uplift and faulting, rising and falling sea level, landslides, erosion and deposition, floods, and droughts. Landscape features, and areas delineating groups of related features on Santa Rosa Island, are mapped, classified, and described in this paper. Notable landscapes on the island include beaches, coastal plains formed on marine terraces, sand dunes, and sand sheets. In this study, the inland physiography has been classified into 4 areas based on relief and degree of fluvial dissection. Most of the larger streams on the island occupy broad valleys that have been filled with alluvium and later incised to form steep- to vertical-walled arroyos, or barrancas, leaving a relict floodplain above the present channel. A better understanding of the processes and mechanisms that created these landscapes enhances visitors’ enjoyment of their surroundings and contributes to improving land and resource management strategies in order to optimize and balance the multiple goals of conservation, preservation, restoration, and visitor experience.

    Full Text Available The problems affecting the small Renaissance chapel dedicated to Virgen de la Antigua in the parish church of San Miguel in Morón de la Frontera have led to a state of decay verging on total ruin. When we addressed the intervention required by the building, we realised that we needed to know what had caused the structural instability which had led to urgent bracing in 1998. We knew that we could not simply take the current state of the building as our starting point for calculating the necessary reinforcements. The precariousness of its current state reveals the scars and traces of a complex fate which we would have to decode by designing and programming a series of examinations to arrive at a diagnosis. All of these processes have enabled us to identify and understand the various phases of construction and destruction, that is, to acquire the necessary - although never sufficient - references to conduct the architectural restoration project.Los problemas que aquejan a la pequeña capilla renacentista dedicada a la Virgen de la Antigua, en la iglesia parroquial de San Miguel de Morón de la Frontera, la han llevado a un estado de degradación cercano a la ruina. Al plantearnos la intervención sobre este edificio surgió la necesidad de conocer las causas de la inestabilidad estructural que llevó a su urgente apuntalamiento en 1998. Para ello entendíamos que no era suficiente tomar como punto de partida el estado actual del edificio y calcular sobre él los refuerzos necesarios. El precario estado en que se encuentra muestra, a simple vista, las cicatrices y huellas de un complejo devenir que debíamos descodificar, diseñando para ello una serie de trabajos de auscultación y reconocimiento. Todos estos trabajos nos han permitido conocer y comprender sus etapas constructivas y destructivas, esto es, contar con las referencias necesarias, aunque nunca suficientes, para la realización del proyecto de restauración arquitectónica.

  14. Miguel Prieto y la escenografía en la España de los años treinta

    Full Text Available The artist Miguel Prieto (1907-1956 worked in three main areas: painting-drawing, graphic design and set design. The latter was the one in which he demonstrated most interest in avant-garde and political commitment during the thirties, but due to his subsequent Mexican exile, has not been dealt with in recent research. This article, focused on his years in Spain, analyses his contributions to scenic design. Prieto’s first professional period, when he worked for the puppet theatre, coincided with the young Second Republic and then the convulsion of the Civil War. This popular genre was utilized for agitation, propaganda and the revolutionary theatre, and adopted both the classical repertoire and modern works by Alberti, Dieste, Lorca and other committed youthful intellectuals.

    Las tres grandes vertientes en las que el pintor Miguel Prieto (1907-1956 plasmó su creatividad fueron la pintura-dibujo, el diseño gráfico y la escenografía. Esta última, que fue en la que más énfasis puso tanto en su acercamiento a la vanguardia y el compromiso socio-político de los años treinta, como en los años finales de su trayectoria en el exilio mexicano, no ha sido suficientemente atendida. Este artículo, centrado en esa etapa española, analiza y pone en valor la aportación a la escena de Prieto coincidente con esos momentos de construcción de la joven II República y la convulsión de la Guerra Civil, que principalmente se plasmó en la escenificación de espectáculos de guiñol (extraídos del repertorio clásico o expresamente escritos por Alberti, Dieste, Lorca y otros jóvenes inquietos, ya que su tradición y clara aceptación popular los convertían en adecuado instrumento para encauzar la agitación y propaganda que querían sembrar el teatro revolucionario y la creatividad más avanzada y comprometida.

    Full Text Available Carrying out restoration works at old constructions offers a valuable opportunity for learning more about the building legacy they conceal, especially when they are the result of historical remodellings and extensions. A knowledge of the solutions that the builders adopted for stone walls, arches and vaults, of the construction logics followed and of the techniques applied provides vital clues for understanding their structural behaviour and the reasons for the discernible lesions, and for evaluating their condition correctly. During our restoration of the chapel of La Antigua adjoining the church of San Miguel in Morón, we were able to observe this legacy and confirm the importance of compiling knowledge obtained from various sources such as the graphic survey of the construction, the building sequence, geotechnical and documentary studies, and the analysis of the formal graphic control systems used to draw the plans, known as architecture treatises and manuscripts.Las obras de restauración sobre construcciones antiguas es un momento indispensable para el conocimiento del legado constructivo que permanece oculto en ellas, sobre todo cuando son resultado de reformas y ampliaciones históricas. El conocimiento de las soluciones en muros, arcos y bóvedas de piedra adoptadas por los constructores, la lógica constructiva seguida y las técnicas aplicadas, es indispensable para comprender su comportamiento estructural, las causas de las lesiones perceptibles, y proceder a su correcta evaluación. Durante la restauración de la capilla de La Antigua, adosada al templo de San Miguel en Morón, hemos podido observar este legado y confirmar hasta que punto era necesario su conocimiento interrelacionando diversas fuentes como la información obtenida mediante su levantamiento gráfico, la lectura de la secuencia constructiva, los estudios geotécnicos y documentales, así como el análisis de los sistemas gráficos de control formal que permitieron su

    Full Text Available La Chronique du Connétable, au-delà du propos apologétique centré sur la figure de Miguel de Iranzo, peut être lue comme un récit circonstancié et détaillé des pratiques itinérantes de la royauté, pratiques partagées par les élites nobiliaires. Il s’agit, dans un premier temps, de définir le concept de cour puis, dans un second temps, d’établir une typologie des déplacements opérés par le monarque durant deux années, 1458 et 1459. Cette analyse révèle que la Chronique donne du gouvernement d’Henri IV une vision plus contrastée et par là même moins négative que celle proposée généralement par les chroniques commanditées a posteriori par les Rois Catholiques dans un souci de propagande.La Crónica del Condestable, más allá de su contenido apologético centrado en la figura de Miguel de Iranzo, se da a leer como un relato detallado de las prácticas itinerantes de la realeza, prácticas compartidas por las élites nobiliarias. Se trata, primero, de definir el concepto de corte, y luego de establecer una tipología de los desplazamientos realizados por el monarca durante dos años, 1458 y 1459. El análisis pone en evidencia que la Crónica propone del gobierno de Enrique IV una visión matizada y por lo tanto menos negativa que la visión que encontramos en las crónicas comanditadas en años posteriores por los Reyes Católicos con una meta propagandista.

    The IL4 gene is located on chromosome 5q23.3-31.2. Polymorphisms within this cytokine gene, like the derivative allele T of IL4-590, have been reported as being associated to elevated IgE serum levels and asthma. In the present work, the allelic and genotypic frequency of the IL4-590 and IL4 RP2 polymorphisms was carried out in 599 individuals from Madeira, Azores, Portugal mainland, Cape Verde and Guinea-Bissau and in a sample of 101 asthmatics from Madeira population. In all populations the polymorphisms were in LD and presented a significant dissimilar allelic and genotypic distribution (pMadeira when compared to Azores. Significant differences regarding both loci were found between Madeira population and the group of asthmatics. Genotype 183183TT frequency is higher for African populations while 253253CC prevails in Caucasian populations. The existence of a Hardy-Weinberg Disequilibrium in Guinea-Bissau population not observed in neutral markers leads to the hypothesis of natural selection occurring in these loci probably associated to a rapid population growth an hypothesis strengthened by neutral STRs D5S818 and CSF1PO gene diversity.

  20. La estética del reposo en la representación de las pequeñas ciudades provincianas de la prosa de Azorín

    Full Text Available Este artículo analiza la estética del reposo y la pequeña filosofía en la obra de Azorín, asociada a la representación de los pueblos y las ciudades abúlicas. El Eterno retorno de las cosas, desde una variante pesimista de la propuesta de Nietzsche, domina la temporalidad de las pequeñas ciudades provincianas representadas en sus novelas y ensayos: la noción de Progreso ha desaparecido. Domina en este espacio la repetición monótona de los mismos ritos y prácticas. Para Azorín, ante este panorama nihilista, el sujeto de inquietudes intelectuales debe encontrar su lugar en el mundo mediante el disfrute modesto de los pequeños placeres, aquellos proporcionados por los objetos y las experiencias cotidianas, símbolos del ‘alma nacional’. Este es el programa de acción de la pequeña filosofía. Su formulación literaria se canaliza a través de la estética del reposo, que describe el silencio, la quietud, el ritmo pausado de las actividades y los acompasados sonidos de las campanas de estos espacios sociales.
