  1. Space schemes of ecological zonation and morphology of the atolls lagoons and reef complex of an oceanic archipelago of the Caribbean: San Andres and Providence (Colombia)

    International Nuclear Information System (INIS)

    The oceanic atolls and reef-complexes of the Archipelago of San Andres and Providencia exhibit semi-enclosed to rather open lagoon basins, where various characteristic bottom habitats occur. Certain areas of the lagoon floor are covered by sediments, being in some settings vegetated by algae or sea grass, and other areas by coralline framework of different types according to the composition and dominance of coral species and to their morphology and level of reef development. This study seeks to determine the spatial distribution patterns of lagoon bottom habitats based on the analysis of gradients of most relevant physical factors. Patterns in the occurrence and abundance of most habitats became evident in relation with wave-energy level, water depth, and the occurrence of islands. Some morphological reef types are oriented in a preferential direction and show spatial arrangements of development that are presumably related to prevailing current speed and direction and wave exposure

  2. Marine macroalgae in the agronomy and potential use of floating sargassum for manure production in the San Andres and Providencia Archipelago, Colombia

    International Nuclear Information System (INIS)

    An account is made on the use of marine macroalgae in agronomy and the potential that floating Sargassum arriving to san Andres and Providencia has for this activity. This Sargassum, which has been a nuisance for the tourist economy of the islands, promises to be an excellent resource for manure production

  3. Miocene and Pleistocene mollusks from San Andres Island (Caribbean Sea, Colombia) and Paleogeographic considerations

    International Nuclear Information System (INIS)

    San Andres Island is the largest emerged portion of the oceanic archipelago of San Andres and Providencia, southwestern Caribbean Sea; it originated as a coralline atoll during Miocene times. The central and highest part of the island consists of a calcareous crest, the San Andres Formation, formed by Neogene lagoonal and reefal deposits. This crest is surrounded by a calcareous platform of Pleistocene age (San Luis Formation) which emerges only along the island coast, whereas its most part is submerged and covered by a Recent reef complex. Fossil material of molluscs from these two formations was collected in various sites throughout the island and taxonomically identified. In the four sites sampled in the San Andres Formation, material belonging to 19 gastropod and 37 bivalve species was obtained, most of them relatively well represented in other geologic formations of the Caribbean region that are stratigraphically situated between the upper Miocene and the middle Pliocene. Some elements occurring in this formation, such as Ostrea haitiensis, Meretrix dariena and Siphocypraea henekeni, were widely distributed in the Caribbean Miocene Province. In the San Luis Formation, material belonging to 18 gastropod and 11 bivalve species was obtained, most of them also represented in the Recent molluscan fauna of the region. The estimated age of this formation is Sangamonian, hence corresponding to similar formations occurring in Grand Cayman, Jamaica, Hispaniola, the Netherld Cayman, Jamaica, Hispaniola, the Netherlands Antilles and other Caribbean islands, with which it also shows a great similarity in the composition of the molluscan fauna.

    Full Text Available A partir de datos registrados en 1994 y 1995 durante un estudio de línea de base llevado a cabo en cuatro atolones del archipiélago de San Andrés y Providencia (Albuquerque, Courtown, Roncador y Serrana), se analizó la incidencia de la depredación por peces en coral vivo y su relación con la abundan [...] cia de los peces loro Sparisoma viride y Scarus vetula. De las especies de corales depredadas, Montastraea annularis y M. faveolata presentaron la mayor incidencia de depredación, con 25.9% y 18.7% respectivamente. Se encontró que no hay diferencias significativas en la incidencia de depredación entre los atolones (Kruskal-Wallis, p = 0.07). Al comparar entre unidades geomorfológicas, la laguna presentó la mayor incidencia de depredación (14.3%) e igualmente las mayores abundancias de S. viride y S. vetula, sin embargo no se encontró una relación significativa entre ambas variables. Las mayores incidencias de depredación y abundancia de loros en la laguna pueden estar asociadas con la dominancia en este ambiente del complejo Montastraea spp., puesto que dichos corales se han reconocido como los sustratos de pastoreo preferidos por estos peces loro. La depredación por peces, sumada a los demás factores de deterioro presentes en los atolones, probablemente ha contribuido a la degradación reciente de sus arrecifes coralinos. Abstract in english Based on data recorded in 1994 and 1995 during a baseline study carried out at four western Caribbean atolls (Albuquerque, Courtown, Roncador and Serrana) of the San Andrés and Providencia archipelago, the incidence of hard coral predation by fishes and its relation with the abundance of the parrotf [...] ishes Sparisoma viride and Scarus vetula was analyzed. Among affected corals, Montastraea annularis and M. faveolata showed the highest incidence of fish bites (29.5% and 18.7% respectively). There were no significant differences between the atolls on the incidence of coral predation by fishes (Kruskall-Wallis, p = 0.07). When comparing between geomorphologic units the lagoon showed the highest level of predation (14.3%), and also the largest populations of S. viride and S. vetula, but both parameters were not significantly related. Highest predatory incidence and parrotfish abundance in the lagoon could be related to the dominance of the Montastraea spp. complex in this environment, because these coral species have been recognized as the preferred grazing substrates for the two parrotfishes. The predatory activity by the parrotfishes probably has contributed to the general degradation process of the coral reefs in the atolls, when combined with the other agents of stress.

  5. Origins of the Salado, Seven Rivers, and San Andres salt margins in Texas and New Mexico: Revision 1: Topical report

    International Nuclear Information System (INIS)

    The present boundaries of the San Andres, Seven Rivers, and Salado salts generally lie along the periphery of the Palo Duro and Tucumcari Basins. Various geologic mechanisms occurring singularly or in combination determined the positions of the salt margins. These mechanisms include nondeposition of salt and syndepositional and postdepositional dissolution. In New Mexico, San Andres units pinch out against the Pedernal and Sierra Grande Uplifts, indicating that nondeposition established the original salt margins there. Syndepositional dissolution of exposed Upper San Andres salts occurred in response to Guadalupian upwarp of the basin margins. Triassic erosion differentially removed Permian salt-bearing formations along the uplifts. Late Tertiary dissolution is indicated by fill of north-south trending collapse valleys. In Texas, Guadalupian upwarp along the Amarillo Uplift caused pinchout of Units 2 and 3 in the Lower San Andres and influenced the deposition of subsequent salt-bearing strata. The discontinuity of Upper San Andres evaporites across the Amarillo Uplift suggests syndepositional dissolution. Along the eastern and northeastern basin margin, dissolution may have accompanied Triassic erosion of locally uplifted Upper Permian strata. Tertiary dissolution is recognized beneath anomalously thick Ogallala Formation sections that overlie collasped Permian strata. 49 refs., 31 figs., 2 tabs

  6. Composition and stratigraphic distribution of materials in the lower San Andres Salt Unit

    International Nuclear Information System (INIS)

    The salt bed in depositional cycle 4 of the Permian Lower San Andres Formation, Palo Duro Basin, Deaf Smith County, Texas consists of massive salt interlayered with discrete bands and beds of anhydrite and claystone. The massive salt consists of about 90% halite, with 7% anhydrite and 3% clays disseminated in and among the halite crystals. The halite in this salt bed contains fluid inclusions filled with a (Na, K, Mg)Cl brine, with an average Mg concentration of about 50,000 mg/liter. The anhydrite in the salt will saturate the brines in CaSO4, which in turn may coat the waste package with anhydrite because of the retrograde solubility of CaSO4. This may increase waste package lifetime to failure by corrosion. 16 references, 5 figures, 1 table

The response of the surface layer, to atmospheric events, allowed to differentiate the pass of two cold fron [...] ts by Johnny Cay station (San Andres Island) and the arrival of the "Veranillo" in the sensors of Tesoro Island (Islas del Rosario, Cartagena). The cold fronts produced a decrease in the atmospheric pressure, air temperature, caused radical changes in wind direction and speed followed by precipitation. This situation lowered the sea surface temperature, the surface layer pH and rose momentarily the sea level. The "Veranillo" came to Archipelago of Rosario generating a strong increase in wind speed and solar radiation. The response in the sea surface layer was evident through a significant increase in sea level.

  10. Survey of benthic dinoflagellates associated to beds of Thalassia testudinumin San Andres Island, Seaflower biosphere reserve, Caribbean Colombia

    International Nuclear Information System (INIS)

    In order to determine the occurrence of epiphytic toxic dinoflagellates in the coastal waters of San Andres Island, Caribbean Colombia, we analyzed the sea grass beds on the northern and eastern sides of the island. We found seven species of toxicogenic dinoflagellates, belonging to the genera Prorocentrum and Ostreopsis. The cell densities were generally low if compared with previous studies in other Caribbean sites, ranging from 0 to 836 cells/dry weights. The species encountered are known to produce toxins causing the diarrheic shellfish poisoning and ciguatera, poisonings which have been documented in the island.

    Full Text Available El objetivo de este artículo es analizar el estado actual de la recolonización del archipiélago de San Benito por el lobo fino de Guadalupe (Arctocephalus townsendi). El archipiélago tiene una gran importancia para esta especie, ya que puede consolidarse en un futuro como otro sitio de reproducción, [...] lo que implicaría un gran avance en su recuperación natural. El incremento y la estructura poblacional, el comportamiento alimenticio, la duración de los viajes de alimentación (que evidencian una fuente importante de alimento cercana) y la atención a las crías son factores que permiten analizar y estudiar el proceso de crecimiento de San Benito como una nueva colonia reproductiva. Esta expansión del territorio puede ser reflejo de la naturaleza gregaria de la especie y la fidelidad hacia los sitios reproductivos. La importancia de este trabajo radica en que es una descripción inicial de la recolonización de una especie que estuvo a punto de desaparecer. Puede esperarse que el número de individuos en el archipiélago continúe aumentando, ya que es poco probable que a corto plazo el espacio reproductivo y la disponibilidad de alimento limiten el nacimiento de crías y el crecimiento de la población. Abstract in english The aim of this paper is to analize the re-colonization process of the San Benito Archipelago by the Guadalupe fur seal (Arctocephalus townsendi). The archipelago is of great importance for the species, since it can be consolidated in the future as a breeding colony, which would imply a great achiev [...] ement for the fur seal's natural recovery. Population growth, population structure, feeding behavior, foraging trips duration (which shows an important feeding area near), behavior and pup attendance, are characteristics that help analyze and study this process; where San Benito grows as a colony and, therefore, is established as a new breeding colony. Furthermore, this expansion of the breeding territory might reflect the gregarious nature of the species, and fidelity to breeding areas as well. The importance of this work is that it is an initial description of the recolonization of a species that almost disappears. It can be expected to continue increasing the number of individuals at the archipelago, since it is unlikely that in a short period of time, the breeding territory and the food availability limit the birth of offspring and the population growth.

  12. An Integrated Study of the Grayburg/San Andres Reservoir, Foster and South Cowden Fields, Ector County Texas

    For a part of the Foster and South Cowden (Grayburg-San Andres) oil fields, improvement in oil production has been accomplished, in part, by using ?pipeline fracturing? technology in the most recent completion to improve fluid flow rates, and filtration of waterflood injection water to preserve reservoir permeability. The 3D seismic survey acquired in conjunction with this DOE project has been used to calculate a 3D seismic inversion model, which has been analyzed to provide detailed maps of porosity within the productive upper 250 feet of the Grayburg Formation. Geologic data, particularly from logs and cores, have been combined with the geophysical interpretation and production history information to develop a model of the reservoir that defines estimations of remaining producible oil. The integrated result is greater than the sum of its parts, since no single data form adequately describes the reservoir. Each discipline relies upon computer software that runs on PC-type computers, allowing virtually any size company to affordably access the technology required to achieve similar results.

  13. Petrographic report on samples from units 4 and 5 salt, lower San Andres formation, J. Friemel No. 1 well, Deaf Smith County, Palo Duro Basin, Texas

    International Nuclear Information System (INIS)

    This report presents the results of mineralogic and petrographic analyses performed on samples of salt-bearing rock from a potential repository site in the Palo Duro Basin, Texas. The samples are from Permian Units 4 and 5 salt, Lower San Andres Formation, J. Friemel No. 1 well, Deaf Smith County, Texas. The mineralogic and petrographic data were obtained from polished thin sections cut parallel to the axis of the core for each sample. The polished thin sections were examined in order to determine the abundances of soluble (halite) and insoluble components (anhydrite, clay, carbonate, quartz, gypsum, etc.). The information reported here includes mineral associations (detrital, authigenic, cement, alteration, etc.), texture, grain size, and sedimentary fabrics. The report also includes representative photomicrographs with superimposed bar scales. Photomicrographs of polished thin sections have the up-core direction designated. X-ray diffraction was also used for identification of soluble and insoluble minerals. 7 refs., 2 tabs

    Full Text Available El archipiélago de San Bernardo ha sido reconocido como un hábitat de anidación esporádica y alimentación de las tortugas verde, carey y caguamo. Teniendo en cuenta estos antecedentes y debido a que el archipiélago presenta áreas coralinas, praderas de pastos marinos y playas arenosas relevantes en [...] el Caribe colombiano, cuya oferta ambiental no ha sido descrita para el recurso tortugas marinas, se realizó este estudio entre julio y octubre de 2002, cuyos objetivos fueron describir las playas de anidación y zonas de alimentación en función de su geomorfología, aspectos bióticos y, para las últimas áreas, algunos oceanográficos. Fueron evaluadas siete playas potenciales de anidación y 20 bajos de alimentación para identificar las amenazas naturales y antrópicas para las tortugas y los hábitats. La carey es la única especie que aún anida en la zona, pero sus áreas de desove se han reducido por la erosión del mar y la construcción existente (blindaje). Los únicos lugares de anidación encontrados fueron el costado sureste de isla Palma y el norte de isla Tintipán. En áreas de alimentación, la mayoría de las estaciones (n=14) presentaron pastos marinos con predominio de fondo blando. A partir de la caracterización de estas áreas se describieron como objeto de alimentación de la carey nueve especies de esponjas y tres de algas. Con el objeto de documentar los componentes de la dieta de las tortugas en el archipiélago, cinco contenidos estomacales de carey y seis de verde fueron analizados. Los ítems más abundantes para la carey fueron las esponjas Eicionemia sp. y Geodia sp. (96% en peso seco) y en la tortuga verde los pastos Thalassia testudinum y Syringodium filiforme (98% en peso seco), observados comúnmente en campo. En áreas de forrajeo la captura directa de tortugas juveniles y adultas fue la amenaza principal, por lo que se deben dirigir esfuerzos para reducir el número de individuos capturados, determinar el grado de intervención y las posibles soluciones. Abstract in english The San Bernardo Archipelago, in the Colombian Caribbean zone, is well recognized for being a sporadic nesting and feeding area for the green, hawksbill and loggerhead turtles. Due to the fact that the San Bernardo Archipelago has outstanding coral areas, marine grasses and sandy beaches and their e [...] nvironmental offers for the marine turtles have not been described yet, it was opportune to carry out this study between July and October of 2002. Thus, this research tends to fill this gap by describing the nesting beaches and feeding areas according to their geomorphologic and biotic aspects and, for the later areas, some oceanographic aspects too. Seven potential nesting beaches and 20 stations on feeding areas were evaluated to identify natural and anthropogenic threats that could affect sea turtles and their habitats. The only species that still nests on these islands is the hawksbill turtle, but its nesting areas are being reduced because of erosion and constructions on the beach. The remaining nesting places observed during the 2002 season were on the southeastern side of Palma island and on the northern side of Tintipán island. In the feeding areas, the majority of stations (n=14) have marine grass with predominance of soft bottom. From these characterizations in the feeding areas, nine sponges and two seaweeds species were described as index species hawksbill turtles feed on. In order to gather information about the marine turtles diet components, five stomach contents of hawskbill turtle and six of green turtle were analyzed. They showed that the sponges Eicionemia sp. and Geodia sp. are the principal diet components (96% dry weight) in the hawksbill turtle diet. In the case of the green turtle, Thalassia testudinum and Syringodium filiforme grasses were identified as index species (98% dry weight); they were the most common during the field observations. The principal threat for sea turtles was the direct capture of adults and juveniles in feeding areas, for what effort

    Full Text Available Exploitation of the Guadalupe fur seal (GFS during the XVIII and XIX centuries almost extirpated the species. GFS were distributed from the Revillagigedo islands (Mexico to the gulf of Farallones (USA. At present, reproductive colonies are found at Guadalupe Island and San Benito Archipelago (SBA. The aim of this work was to analyze the process of re-colonization and the current status of GFS at SBA. The first births and the occupation of the west island of the SBA are also reported. Census data from 1997 to 2007 indicated an annual growth rate for the population of 21.6%. The population size, growth tendency of the colony, reproductive biology, and food preferences were also studied. A total of 2,227 GFS were counted at SBA. Three squid species (Loligo opalescens, Onychoteuthis banksii, Dosidicus gigas were found to be the main dietary components. Territoriality, activity patterns, and reproductive behavior were similar for the seals from Guadalupe Island and SBA. The mean growth rate for pups from SBA was calculated and compared to that of the pups at Guadalupe Island (SBA: 6.7 ± 1.4 kg, 68.9 ± 2.64 cm; Guadalupe Island: 5.9 ± 0.5 kg, 67.29 ± 4.3 cm. The length of food foraging trips by females was measured, suggesting that the SBA colony is probably near an important feeding area. Maternal care patterns could indicate different strategies of nursing-foraging trips between the SBA and Guadalupe Island. The population of fur seals at SBA is expected to increase as there are no limitations in terms of reproductive space or available food resources in the area.La explotación del lobo fino de Guadalupe (LFG durante los siglos XVIII y XIX casi extinguió a la especie.

El subgrupo banano AAA presentó dos materiales Gros Michel (denominados Común y Chino) y uno de banano (Rojo). El plátano tiene gran importancia para los agricultores de la Isla, siendo el Boscó el clon más aceptado entre consumidores por su adaptación a las condiciones edafológicas y climáticas. El banano es menos cultivado; ya que los suelos, el clima y las enfermedades como sigatoka negra, condicionaron el desarrollo de clones. El trabajo sugiere prácticas de fácil implementación que podrían aumentar la producción en los sistemas de huerto mixto tropical que predominan en la Isla. Abstract in english During the first semester, 2005 we studied the plantain and banana cultivars in small farms of 15 volunteer regular producers, who were participating in joint programs of the Agriculture and Fisheries Secretariat of San Andres Island and the Colombian National University Caribbean Headquarters. We d [...] escribed morphologically the Musa cultivars identified in the island, as well as agricultural practices of the island producers, using the INIBAP, IPGRI and CIRAD (1996) descriptors and bibliographical reviews. We identified four clones within the plantain sub-group Musa AAB: a Horn type and three French-Horn; and within the ABB sub-group a Bluggoe (dubbed “Boscó”) and a Felipita type. The banana sub-group AAA had two Gros Michel type, known as “Banano Común” and “Banano Chino”, as well as one of red banana (“Banano Rojo”). The plantain culture has paramount importance for San Andres farmers, and the clone named “Boscó” is the preferred one for its taste, and its adaptation to the edaphic and climatic conditions. Banana is less cultivated; the soil and the climate, as well as diseases (v.gr. the leaf spot disease or sigatoka) determined the growth of their clones. This work suggests a list of easy to implement agronomic practices that would enhance the production of the predominant producing systems of the island.

    Full Text Available A pesar de la importancia de las capturas del atún de aleta negra Thunnus atlanticus en el noreste de Brasil y en las cercanías del Archipiélago San Pedro y San Pablo (ASPSP), hay una escasez de información sobre su reproducción, especialmente en las islas. La reproducción del atún de aleta negra en [...] este archipiélago se estudió de diciembre 2008 a julio 2010. Con este fin, se recolectaron 361 gónadas de hembras y machos, los machos fueron predominantemente más frecuentes en la muestra total, con una proporción sexual de 1?:2.2 ?. La longitud furcal todos los ejemplares muestreados varió entre 38 y 98 cm, y los machos fueron más abundantes en las clases de mayor longitud. Los valores medios mensuales del índice gonadal (IG) variaron de 6.6 (SD=4.1) a 58.4 (SD=34.7) y de 2.6 (SD=1.3) a 66.2 (SD=30.4) para hembras y machos, respectivamente. Los mayores valores de IG para ambos sexos fueron observados el inicio del primer semestre. Los análisis histológicos mostraron que la mayoría de los ovarios y testículos correspondieron a especímenes aptos para reproducirse. Sin embargo, hembras con ovarios maduros, con gran cantidad de oócitos hidratados y folículos post ovulatorios, se encontraron principalmente de diciembre a marzo, que se considera es la época de reproducción del atún de aleta negra alrededor del ASPSP. Abstract in english The reproduction of Blackfin tuna Thunnus atlanticus has been described for coastal regions, and for a long time, this species was considered to be a strictly continental spawner. Recently, this species was observed around a seamount habitat 500 nautical miles Northeast of Brazil, located between So [...] uth America and Africa. In this study we describe the reproductive biology of Blackfin tuna at Saint Peter and Saint Paul Archipelago (SPSPA). Male and female gonads were sampled from December 2008 to July 2010, and analyzed macro and microscopically. A total of 361 fish were sampled (247 males and 114 females). Males were more common than females, with a sex ratio of 2.2 ?:1?. The fork length (FL) of all sampled specimens ranged from 38 to 98cm, and larger length classes were more frequent in males. It was possible to distinguish six maturity phases for females: immature, developing, spawning capable, actively spawning, regressing and recovering. Five phases were identified for males: immature, developing, spawning capable, actively spawning and recovering. The gonad index (GI) mean monthly values ranged from 6.6 (SD=4.1) to 58.4 (SD=34.7) for females, and from 2.6 (SD=1.3) to 66.2 (SD=30.4) for males. For both sexes, the largest GI values were observed at the beginning of the first semester of the year. Size at first maturity was estimated at 48cm FL and 55cm FL for females and males respectively. Approximately 80% of the specimens were adults and considered to be in reproductive conditions. Histological analysis of the ovaries and testes showed that most of the specimens were sexually mature and were reproductively active during all months of the year. However, females with mature ovaries, with large amounts of hydrated oocytes and post-ovulatory follicles, were mainly found from December to March, thus these months may constitute the main spawning season in SPSPA. Batch fecundity varied between 272 025 and 1 140 584 oocytes for 56 and 68cm FL females respectively. Oocyte development and spawning patterns suggest a multiple spawning behavior. The results revealed that Blackfin tuna is using the SPSPA as a spawning ground, similar to other species commonly observed in the same area during the same reproductive season.

  1. An integrated study of the Grayburg/San Andres Reservoir, Foster and South Cowden Fields, Ector County, Texas. Annual report, August 1, 1996--July 31, 1997

    The objective of this two-phase study is to demonstrate an integrated methodology for reservoir characterization of shallow shelf carbonate reservoir that is feasible, and cost effective for the independent operator. Furthermore, it will provide one of the first public demonstrations of the enhancement of reservoir characterization using high-resolution three dimensional (3D) seismic data. This particular project is evaluating the Grayburg and San Andres reservoirs in the Foster and South Cowden Fields, Ector County, Texas. This 68 year old field was approaching its economic limit and the leases evaluated would have been abandoned in 10 years. A multidisciplinary approach to waterflood design and implementation, along with the addition of reserves by selective infill drilling and deepening, is being applied to this field. This approach in reservoir development will be applicable to a wide range of shallow shelf carbonate reservoirs throughout the US. The first phase of the project included the design, acquisition, and interpretation of the 3D seismic survey, the collection and evaluation of geologic (core and log) data, and engineering (historical production, well test, injection) data from a variety of sources. From this work, a geologically based production history model was simulated. Based on the recommendations made at the end of Phase One, three new wells were drilled, one existing well was deepened, two wells were worked over, one TA`d well was re-entered, and one well was converted to injection. In addition, the quality of the injection water was greatly improved, a step necessary prior to increasing injection in the project area. The realignment of the waterflood and all additional well work await the completion of the seismic based history match and engineering simulation.

    Full Text Available El artículo analiza la riqueza e importancia del concepto de etnomapa, como herramienta de análisis cultural y espacial por medio de un mapa elaborado por pobladores mayas itzaes de dos asentamientos localizados en el Petén, Guatemala. El estudio se llevó a cabo entre octubre 2006 y septiembre de 20 [...] 07, se completó con la aplicación de encuestas mediante muestreo proporcional a unidades familiares itzaes de dos poblados del Petén central, San José (n = 40) y San Andrés (n = 22). A través de la interpretación de la información y mediante el enfoque de sistemas, se logró dilucidar los componentes agrícolas y los recursos naturales que practican y utilizan los mayas en ambas localidades. Los resultados hallados sugieren que los sistemas agrícolas y de utilización de los bosques tropicales húmedos practicados por los itzaes, representan una actividad económica importante, caracterizada por una amplia utilización de especies agrícolas y naturales. Estas actividades representan una base de recursos fundamental para los itzaes. Las características de estos sistemas son comparables a los encontrados en otros estudios en diferentes grupos mayas confirmando la diversidad de posibilidades de los modelos de adaptación y manejo de recursos de los itzaes. La creación del etnomapa valida del profundo conocimiento local, de la distribución territorial de los recursos naturales y antropogénicos. Se posibilita además el analizar los cambios que enfrentan los poblados itzaes, debido a las presiones socioeconómicas y tecnológicas que se desarrollan actualmente en la región del Petén central de Guatemala. Abstract in english This article analyses the richness and importance of the concept of the ethnomap, as a tool for cultural and spatial analyses, based on a map prepared by mayan Itzae inhabitants of two communities located in El Petén, Guatemala. The study took place between October 2006 and September 2007, and inclu [...] ded surveys carried out with a proportional sampling of Itzae family units in two settlements of the central Petén, San José (n = 40) and San Andrés (n = 22). A systems theory was applied in the analysis and interpretation of the data, resulting in the definition of the agricultural components and the natural resources that the Mayas use in the two communities. Findings suggest that the agricultural and tropical forest activities carried out by the Itzaes represent important economic activities, characterised by the use of a wide range of natural and agricultural species. These activities represent a fundamental resource base for the Itzae-maya population. The characteristics of these systems are comparable to those recorded by other studies on different Maya groups, confirming the diversity of possibilities for the adaptation and resource management models of the Itzaes. The ethnomap validates the profound local knowledge of the territorial distribution of anthropogenic and natural resources. It also makes it possible to analyse the changes facing the local Itzae populations, following the socioeconomic and technological pressures that are present in the central Petén region of Guatemala.

    Full Text Available Con el propósito de evaluar la abundancia y la composición de dinoflagelados potencialmente tóxicos asociados al material orgánico flotante (drift) en la isla de San Andrés, se seleccionaron siete sitios de muestreo a lo largo de la margen Norte y Este, paralelos a la barrera arrecifal y a las princ [...] ipales praderas de fanerógamas marinas y macroalgas de la isla. Durante la época de mayor intensidad de vientos, se recolectaron muestras de drift; se identificaron los sustratos a especie y posteriormente se sumergieron en solución 1:1 agua de mar filtrada y solución de Transeau. Luego de agitar vigorosamente las muestras para remover los dinoflagelados, se tamizo la suspensión con una malla de 80 µm y el filtrado se observó al microscopio óptico. Se encontraron cinco sustratos, dos especies de pastos marinos y tres de macroalgas. Sobre los sustratos se identificaron doce especies de dinoflagelados, diez reportadas como tóxicas, causantes de diarrea, parálisis y ciguatera. La abundancia de dinoflagelados varió ampliamente con promedios máximos (±DE) de 15 354±15 749 células/g peso seco de sustrato. De las especies de dinoflagelados, cinco son nuevos registros para San Andrés. No se encontraron diferencias significativas en los valores de diversidad de dinoflagelados entre drift y praderas de pastos y macroalgas, no obstante, la abundancia fue mucho mayor en el drift. Los resultados indican que el drift es un importante sustrato para dinoflagelados y dada su naturaleza flotante, representa tal vez el vector más importante para la dispersión de estos agentes de toxicidad en la isla. Para mitigar el efecto de eventos tóxicos asociados a dinoflagelados en salud pública, pesca y turismo, es necesario diseñar un plan de manejo del material orgánico flotante, que permita mejorar el entendimiento de su composición y dinámica temporal, monitorear las toxinas asociadas e implementar mecanismos de recolección y tratamiento. Abstract in english To assess the composition and abundance of potentially toxic dinoflagellates associated to drift on San Andres island, we selected seven sampling sites along the northern and eastern side of the island. During the wind season, we collected drift samples, identified the main substrates to species, an [...] d submerged them in 1:1 filtered seawater and Transeau solution. After shaking to remove the dinoflagellates, we sieved through an 80 µm screen and analyzed the detached dinoflagellates under an optical microscope. We found five substrates, two seagrass species and three macroalgae. Associated to these substrates, we identified twelve dinoflagellates species, ten of which are reported as toxic and are known to produce diarrhea, paralysis and ciguatera, syndromes reported in San Andrés and other Caribbean places where their frequency is apparently increasing. The dinoflagellate abundance presented strong variation with maximum average values (±SD) of 15354±15749 cel. /g of substrate dry weight. Five of the dinoflagellates associated to drift are new records for the island. We did not found significant differences in diversity of benthic dinoflagellates between drift and seagrass and macroalgae beds; however, the abundance was much higher in drift. The results showed that drift is a very important substrate for potentially toxic dinoflagellates and, considering its buoyant nature, it may represent one of the main dispersion vectors for these species on the island. To mitigate the effect of intoxication events on public health, fisheries and tourism, it is necessary to design a floating organic material management plan, improve the understanding of drift composition and its temporal dynamics, as well as to monitor associated toxins and pursue collection and treatment mechanisms of the floating biomass.

Así mismo, se cuantificó la frecuencia de mortalidad parcial, total, enfermedades y signos de depredación en los juveniles, en 47 cuadrantes de 1m², distribuidos a lo largo de una cuerda guía. Se registró un total de 397 juveniles coralinos pertenecientes a 16 especies. La densidad promedio y riqueza de juveniles no mostraron diferencias significativas entre Reggae Nest y El Faro. La densidad promedio de las localidades fue alta respecto a lo registrado en arrecifes colombianos y baja en relación a otros arrecifes del Caribe. Las especies con valores de importancia mayores, Agaricia agaricites, Scolymia sp. y Porites astreoides, aportaron el 54.9 % de todos los juveniles, lo que concuerda con lo hallado en otros arrecifes del Caribe. Los géneros de juveniles con mayor densidad, cobertura y frecuencia no concordaron con los adultos dominantes (ej. Montastraea, Colpophyllia, Diploria y Siderastrea); ya que M. annularis y Diploria sp. exhibieron los valores más bajos de importancia como juveniles. Las comunidades coralinas de Reggae Nest y El Faro, deterioradas en las últimas décadas, podría recuperarse naturalmente, teniendo en cuenta la siguiente evidencia: 1) alta densidad de corales juveniles respecto al Caribe colombiano; 2) alta riqueza de juveniles, representados en 16 de las 23 especies de corales adultos registrados para la isla; 3) alto porcentaje de especies comunes entre juveniles y adultos (mantenimiento de cada población); 4) bajos porcentajes de mortalidad parcial (0.7 %; 3 juveniles de 397) y de blanqueamiento encontrados en los juveniles (0.5 %; 2 juveniles de 397). Queda aún por comprobar, la sobrevivencia a largo plazo, si estos juveniles son de especies fugitivas o si la comunidad de constructores está siendo reemplazada.

In adittion, in 47 quadrants of 1m² distributed throughout a guide line, frequency of partial mortality, total diseases and depredation signs in juvenile corals were quantified. A total of 397 juveniles of 16 species were registered. The average density and richness of juveniles were not significantly different between Reggae Nest and El Faro. The average density of both localities was high compared to other colombian reefs and lower compared to other reefs in the Caribbean. The species with higher importance value, Agaricia agaricites, Scolymia sp. and Porites astreoides, represented 54.9% of all juveniles, similar to other Caribbean reefs. The genera of juveniles with higher importance value were not the same as the dominant adults (ej. Montastraea, Colpophyllia, Diploria and Siderastrea); which showed the lowest importance value as juveniles (Montastraea annularis and Diploria sp.). The coral communities of Reggae Nest and El Faro, deteriorated in the last decades, could recover naturally, considering the following evidence: 1) high juvenile coral density compared to the Colombian Caribbean; 2) high richness of juveniles, 16 from the 23 coral adults species reported for the island; 3) high percentage of common species between juveniles and adults (maintenance of each population); 4) low partial mortality (0.7%; 3 of 397 juveniles) and bleaching found in juvenile corals (0.5%; 2 juveniles of 397). It is still to verify if these juveniles are fugitive species or if the community of builder species may be replaced.

Charlottesville: University of Virginia Press, 1998. xii + 197 pp. (Cloth US$ 42.50, Paper US$ 18.50 In his most recent theoretical work, Traite du Tout-Monde, Edouard Glissant stresses the virtues of what he calls "archipelagic thinking." "The entire world is becoming an archipelago," he asserts (1997:194, and for this reason we need to distance ourselves from both insular and continental ways of thinking if we are to register the complexities of that global creolization process. The archipelago is situated between the solitary confines of the islands that constitute it and the expansive territory of the mainland toward which it points, relating the one to the other while retaining its own indeterminately distinct identity. For Glissant, actual archipelagos such as the Caribbean are exemplary sites for understanding the complex new relations that ambivalently and chaotically join together all the hitherto unconnected parts of the world. As a consequence of this, the need for understanding the Caribbean as an archipelago becomes ever more pressing: the Caribbean must be considered in its archipelagic totality, as a region that can only be adequately understood through comparative, cross-cultural analysis focusing less on its discrete parts than on the way these parts exist in relation with and to one another.

    Full Text Available Los depósitos de la Aloformación Punta San Andrés (Plio-Pleistoceno), registran la evolución de diferentes estilos de sistemas fluviales. Durante la primera etapa de la misma evolución, se desarrollaron sistemas de carga mixta, con canales de baja sinuosidad y alta participación de depósitos de plan [...] icie de inundación. Durante la segunda etapa, se verificó el cambio hacia un sistema de canales de mayor sinuosidad, entrelazados, donde los depósitos de planicie de inundación no tuvieron tanto protagonismo. Finalmente, la tercera etapa se caracterizó por el desarrollo de un sistema fluvial entrelazado clásico, sin preservación de depósitos de planicie de inundación. Durante la acumulación de la Aloformación Punta San Andrés, la glacioeustacia en asociación con el clima condicionó directamente el balance entre la tasa de generación de acomodación y el aporte sedimentario. Sin embargo, el análisis comparativo de los diversos índices e indicadores (arquitectura fluvial, paleosuelos, etc.) ha mostrado una variabilidad para los sistemas bajo estudio la cual puede asignarse a diferentes jerarquías de procesos. De esta manera, se identificaron ciclos de agradación fluvial representados por una alternancia de alta frecuencia entre paleosuelos vérticos y cálcicos. En este caso las fluctuaciones en el nivel de base fueron las responsables de los cambios cíclicos en la tasa de generación de espacio de acomodación y de aporte sedimentario. La evolución de los sistemas depositacionales identificados puede asignarse a ciclos de mayor jerarquía, los cuales controlaron el diseño del drenaje mediante cambios en el espacio de acomodación y representan cambios en la tasa de generación de espacio de acomodación relacionados a cambios glacieustáticos de escala global. Abstract in english The deposits of the Punta San Andrés Alloformation (Plio-Pleistocene) register the evolution of different styles of fluvial systems.

Finally, the third stage was characterized by the development of a classic braided fluvial system, without any preservation of floodplain deposits. During the Punta San Andrés Alloformation accummulation, glaci-eustatic changes and climate exerted a fundamental control on the balance between generation of accommodation space rate and sedimentary supply. Nevertheless, comparative analysis of the diverse indicators (fluvial architecture, paleosols, etc.) has shown a strong variability for the studied depositional systems that can be assigned to different process hierarchies. In this way, fluvial aggradational cycles are represented by high-frequency alternation between calcic and vertic paleosols. In this case, base level fluctuations were responsible for the cyclic accommodation rate - sediment supply change. The evolution of the identified depositional systems can be assigned to higher-order cycles, which controlled drainage design by changes in accommodation space and represents changes in the rate of generation of accommodation space linked to glaci-eustatic changes at a global scale.

    Full Text Available Los depósitos de la Aloformación Punta San Andrés (Plio-Pleistoceno, registran la evolución de diferentes estilos de sistemas fluviales. Durante la primera etapa de la misma evolución, se desarrollaron sistemas de carga mixta, con canales de baja sinuosidad y alta participación de depósitos de planicie de inundación. Durante la segunda etapa, se verificó el cambio hacia un sistema de canales de mayor sinuosidad, entrelazados, donde los depósitos de planicie de inundación no tuvieron tanto protagonismo. Finalmente, la tercera etapa se caracterizó por el desarrollo de un sistema fluvial entrelazado clásico, sin preservación de depósitos de planicie de inundación. Durante la acumulación de la Aloformación Punta San Andrés, la glacioeustacia en asociación con el clima condicionó directamente el balance entre la tasa de generación de acomodación y el aporte sedimentario. Sin embargo, el análisis comparativo de los diversos índices e indicadores (arquitectura fluvial, paleosuelos, etc. ha mostrado una variabilidad para los sistemas bajo estudio la cual puede asignarse a diferentes jerarquías de procesos. De esta manera, se identificaron ciclos de agradación fluvial representados por una alternancia de alta frecuencia entre paleosuelos vérticos y cálcicos. En este caso las fluctuaciones en el nivel de base fueron las responsables de los cambios cíclicos en la tasa de generación de espacio de acomodación y de aporte sedimentario. La evolución de los sistemas depositacionales identificados puede asignarse a ciclos de mayor jerarquía, los cuales controlaron el diseño del drenaje mediante cambios en el espacio de acomodación y representan cambios en la tasa de generación de espacio de acomodación relacionados a cambios glacieustáticos de escala global.The deposits of the Punta San Andrés Alloformation (Plio-Pleistocene register the evolution of different styles of fluvial systems.

  13. Regional Oceanography of the Philippine Archipelago

    2011-03-01

    Full Text Available Confined by the intricate configuration of the Philippine Archipelago, forced by the monsoonal climate and tides, responding to the remote forcing from the open Pacific and adjacent seas of Southeast Asia, the internal Philippine seas present a challenging environment to both observe and model. The Philippine Experiment (PhilEx observations reported here provide a view of the regional oceanography for specific periods. Interaction with the western Pacific occurs by way of the shallow San Bernardino and Surigao straits. More significant interaction occurs via Mindoro and Panay straits with the South China Sea, which is connected to the open Pacific through Luzon Strait. The Mindoro/Panay throughflow reaches into the Sulu Sea and adjacent Bohol and Sibuyan seas via the Verde Island Passage and the straits of Tablas and Dipolog. The deep, isolated basins are ventilated by flow over confining topographic sills, causing upward displacement of older residence water, made more buoyant by vertical mixing, which is then exported to surrounding seas to close the overturning circulation circuit.

    The dynamics of the seasonal surface circulation in the Philippine Archipelago (117E-128E, 0N-14N) are investigated using a high-resolution Regional Ocean Modeling System (ROMS) for the period of 2004 - March 2008. Three experiments are performed to estimate the relative importance of local, remote and tidal forcing. On annual mean, circulation in the Sulu Sea is dominated by the inflow from the South China Sea at the Mindoro and Balabac Straits, outflow into the Sulawesi Sea at the Sibutu Passage, and cyclonic circulation in the Sulu basin. A strong jet forms in the northeast Sulu Sea when currents from the Mindoro and Tablas Straits converge. Within the Archipelago, strong westward currents in the Bohol Sea carry the western Pacific (WP) Water from the Surigao Strait into the Sulu Sea via the Dipolog Strait. In the Sibuyan Sea, currents flow westward, which carry part of the WP water from the San Bernardino Strait into the Sulu Sea via the Tablas Strait. The surface circulations exhibit strong seasonal variations or reversals from winter to summer. The variations of volume transports above 40m at the Mindoro Strait, Balabac Strait and Sibutu Passage of the Sulu Sea and at the Verde Island Passage are dominated by remote forcing, although local forcing can be large sometimes. At the Tablas and Dipolog Straits, variations of transports result from both remote and local forcing. The cyclonic (anticyclonic) gyres during winter (summer) in the Sulu Sea and seasonally reversing currents in the Archipelago result mainly from local forcing. Nonlinear rectification of tides acts to reduce the mean transports at the Surigao, San Bernardino and Dipolog Straits, and it also affects the Sulu Sea circulation perhaps by tidal mixing and shifting the locations of jets and eddies.

Los análisis revelaron débil similaridad entre la parte interna de Bahía Hooker y las estaciones restantes. Se calcularon los índices de diversidad de Shannon-Wiener, uniformidad de Pielou, riqueza de Margalef y predominio de Simpson a lo largo del estudio; los tres primeros presentaron mayores valores en Bahía Hooker que en Honda, mientras que el índice de predominio fue mayor en Bahía Honda. Hubo organismos pioneros como el anélido Spirorbis sp. y transitorios como los crustáceos; los moluscos parecieron necesitar periodos más prolongados para asentarse. Estas respuestas revelan que características geomorfológicas, presencia o ausencia de corrientes de agua dulce, mareas y lluvias, principalmente, y factores antrópicos pueden influir en el desarrollo de estas comunidades. Dispersión larval y proximidad con otros ecosistemas aumentan o disminuyen las poblaciones; sólo algunos organismos adaptados a condiciones extremas se establecen y mantienen en el área.

A total of 34,175 individuals in 130 experimental units were counted, where the annelids represented the largest proportion (77.1%) from the whole sample. A dendrogram and a nonmetric multidimensional scaling (NMDS) were constructed for each one of the three studied taxa. The analyses showed a weak similarity between the internal part of the Hooker Bay and the remaining stations. Shannon-Wiener diversity, Pielou evenness, Margalef richness and Simpson predominance indexes were calculated throughout the study; the three first indices showed greater values in Hooker Bay than in Honda Bay, while the predominance index was greater in Bay Honda. There were pioneers organisms such as Spirorbis sp., and transient ones, such as crustaceans, whilst molluscs seemed to need longer periods to settle in. These responses reveal that geomorphological characteristics, presence or absence of freshwater currents, tides and rainfall mainly, as well as anthropic factors can influence the development of these communities. Larval dispersion and the proximity to other ecosystems increase or reduce the populations, and only some organisms, adapted to extreme conditions, settle down and maintain in the area. Under favorable conditions, abundance and species diversity tend to increase

  1. Island Movements: Thinking with the Archipelago

    Directory of Open Access Journals (Sweden)

    Jonathan Pugh

    2013-05-01

    Full Text Available Whether in Homer or Plato, Shakespeare or Huxley, throughout history, thinking about islands has shaped how we think about human nature and our place in the world. However, to date archipelagos have received far less attention. This is problematic because we live, increasingly, in a world of island-island movements and not static forms. Not only in the more obvious cases of the Caribbean, Hawaii or the Philippines but, as Stratford et al (2011 say, many ‘continental forms’ like Canada and Australia are in fact archipelagos composed of thousands of island movements. To this list we can add more manufactured archipelagos: wind turbine arrays, industrial oil and military constellations. The key question therefore arises: what does it mean to think with the archipelago? This paper argues firstly that archipelagic thinking denaturalizes the conceptual basis of space and place, and therefore engages ‘the spatial turn’ presently sweeping the social sciences and humanities. Secondly, such thinking highlights the trope of what I call ‘metamorphosis’, of the adaptation and transformation of material, cultural and political practices through island movements. In both cases, I argue that thinking with the archipelago requires an important shift in how we frame analysis and engagement.

    The chemical quality of water and sediment was analyzed in some bays of Sabana-Camaguey Archipelago (SCA). This analysis was done using the existing information that covers from 1976 to 2011. In the rainy one there was oxygen sub-saturation in the bays of West Santa Clara, East Santa Clara, Puerto de Sagua and Los Perros. The nature of organic matter was quite complex and BOD5 and COD values greater than 2 mg.L-1prevailed. The ammonia concentrations were between 2 and 5 ??mol.L -1, and organic nitrogen represented 90 % of total nitrogen. Phosphorus in water was not very abundant, it acted as limiting nutrient for primary producers. Sediments were characterized by significant amounts of organic carbon and low content of organic nitrogen. The bays of Cardenas, San Juan de los Remedios, Buenavista and Los Perros, were impacts of heavy metals

    The dynamics of the seasonal surface circulation in the Philippine Archipelago (117°E-128°E, 0°N-14°N) are investigated using a high-resolution configuration of the Regional Ocean Modeling System (ROMS) for the period of January 2004-March 2008. Three experiments were performed to estimate the relative importance of local, remote and tidal forcing. On the annual mean, the circulation in the Sulu Sea shows inflow from the South China Sea at the Mindoro and Balabac Straits, outflow into the Sulawesi Sea at the Sibutu Passage, and cyclonic circulation in the southern basin. A strong jet with a maximum speed exceeding 100 cm s -1 forms in the northeast Sulu Sea where currents from the Mindoro and Tablas Straits converge. Within the Archipelago, strong westward currents in the Bohol Sea carry the surface water of the western Pacific (WP) from the Surigao Strait into the Sulu Sea via the Dipolog Strait. In the Sibuyan Sea, currents flow westward, which carry the surface water from the WP near the San Bernardino Strait into the Sulu Sea via the Tablas Strait. These surface currents exhibit strong variations or reversals from winter to summer. The cyclonic (anticyclonic) circulation during winter (summer) in the Sulu Sea and seasonally reversing currents within the Archipelago region during the peak of the winter (summer) monsoon result mainly from local wind forcing, while remote forcing dominates the current variations at the Mindoro Strait, western Sulu Sea and Sibutu passage before the monsoons reach their peaks. The temporal variations (with the mean removed), also referred to as anomalies, of volume transports in the upper 40 m at eight major Straits are caused predominantly by remote forcing, although local forcing can be large during sometime of a year. For example, at the Mindoro Strait, the correlation between the time series of transport anomalies due to total forcing (local, remote and tides) and that due only to the remote forcing is 0.81 above 95% significance, comparing to the correlation of 0.64 between the total and local forcing. Similarly, at the Sibutu Passage, the correlation is 0.96 for total versus remote effects, comparing to 0.53 for total versus local forcing. The standard deviations of transports from the total, remote and local effects are 0.59 Sv, 0.50 Sv, and 0.36 Sv, respectively, at the Mindoro Strait; and 1.21 Sv, 1.13 Sv, and 0.59 Sv at the Sibutu Passage. Nonlinear rectification of tides reduces the mean westward transports at the Surigao, San Bernardino and Dipolog Straits, and it also has non-negligible influence on the seasonal circulation in the Sulu Sea.

  17. New geological data of New Siberian Archipelago

    Science.gov (United States)

    Sobolev, Nikolay; Petrov, Evgeniy

    2014-05-01

    The area of New Siberian Archipelago (NSA) encompasses different tectonic blocks is a clue for reconstruction of geological structure and geodynamic evolution of East Arctic. According to palaeomagnetic study two parts of the archipelago - Bennett and Anjou Islands formed a single continental block at least from the Early Palaeozoic. Isotope dating of De Long Islands igneous and sedimentary rocks suggests Neoproterozoic (Baikalian) age of its basement. The De Long platform sedimentary cover may be subdivided into two complexes: (1) intermediate of PZ-J variously deformed and metamorphosed rocks and (2) K-KZ of weakly lithified sediments. The former complex comprises the Cambrian riftogenic volcanic-clastic member which overlain by Cambrian-Ordovician turbiditic sequence, deposited on a continental margin. This Lower Palaeozoic complex is unconformably overlain by Early Cretaceous (K-Ar age of c.120 Ma) basalts with HALIP petrochemical affinities. In Anjou Islands the intermediate sedimentary complex encompasses the lower Ordovician -Lower Carboniferous sequence of shallow-marine limestone and subordinate dolomite, mudstone and sandstone that bear fossils characteristic of the Siberian biogeographic province. The upper Mid Carboniferous - Jurassic part is dominated by shallow-marine clastic sediments, mainly clays. The K-KZ complex rests upon the lower one with angular unconformity and consists mainly of coal-bearing clastic sediments with rhyolite lavas and tuffs in the bottom (117-110 Ma by K-Ar) while the complexe's upper part contains intraplate alkalic basalt and Neogene-Quaternary limburgite. The De-Long-Anjou block's features of geology and evolution resemble those of Wrangel Island located some 1000 km eastward. The Laptev Sea shelf outcrops in intrashelf rises (Belkovsky and Stolbovoy Islands) where its geology and structure may be observed directly. On Belkovsky Island non-dislocated Oligocene-Miocene sedimentary cover of littoral-marine coal-bearing unconformably overlies folded basement. The latter encompasses two sedimentary units: the Middle Devonian shallow-marine carbonate and Late-Devonian-Permian olistostrome - flysch deposited in transitional environment from carbonate platform to passive margin. Dating of detrital zircons suggests the Siberian Platform and Taimyr-Severnaya Zemlya areas as the most possible provenance. The magmatic activity on Belkovsky Island resulted in formation of Early Triassic gabbro-dolerite similar to the Siberian Platform traps. Proximity of Belkovsky Island to the north of Verkhoyansk foldbelt allows continuation of the latter into the Laptev Sea shelf. The geology of Bolshoy Lyakhovsky Island is discrepant from the rest of the NSA. In the south of Bolshoy Lyakhovsky Island the ophiolite crops complex out: it is composed of tectonic melange of serpentinized peridotite, bandedf gabbro, pillow-basalt, and pelagic sediments (black shales and cherts). All the rocks underwent epidot - amphibolite, glaucophane and greenschist facies metamorphism. The ophiolite is intruded by various in composition igneous massifs - from gabbro-diorite to leuco-granite, which occurred at 110-120 Ma. The Bolshoy Lyakhovsky Island structure is thought to be a westerly continuation of the South Anui suture of Chukchi.

  3. Investigating the multifractality of point precipitation in the Madeira archipelago

    Directory of Open Access Journals (Sweden)

    M. I. P. de Lima

    2009-04-01

    Full Text Available The purpose of this work is to contribute to a better understanding of the variability of precipitation in the Madeira archipelago. This archipelago is located in the Atlantic subtropical belt under the direct influence of the Azores high pressure system. It is formed by Madeira Island (728 km2 and Porto Santo Island (42 km2 and by two other groups of very small inhabited islands. The complex topography of the islands in the Madeira archipelago and their small size play a crucial role in the local precipitation regime, which is marked by high spatial variability.

    This paper explores the invariance of properties manifested across scales and determines the fractal and multifractal behaviour observed in the temporal structure of precipitation using daily and 10-min time series from several locations scattered over the main islands. The period covered by the precipitation records is 34 years for the daily data and almost 4 months for the 10-min data. The results show that the temporal structure of precipitation in the Madeira Archipelago exhibits scale-invariant and multifractal properties. The empirical exponent functions describing the scaling statistical properties of the precipitation intensity were characterized using multifractal parameters; these parameters are increasing our awareness of the dynamics of this process in these islands.

  8. Pelagic microplastics around an archipelago of the Equatorial Atlantic.

    Plastic marine debris is presently widely recognised as an important environmental pollutant. Such debris is reported in every habitat of the oceans, from urban tourist beaches to remote islands and from the ocean surface to submarine canyons, and is found buried and deposited on sandy and cobble beaches. Plastic marine debris varies from micrometres to several metres in length and is potentially ingested by animals of every level of the marine food web. Here, we show that synthetic polymers are present in subsurface plankton samples around Saint Peter and Saint Paul Archipelago in the Equatorial Atlantic Ocean. To explain the distribution of microplastics around the Archipelago, we proposed a generalised linear model (GLM) that suggests the existence of an outward gradient of mean plastic-particle densities. Plastic items can be autochthonous or transported over large oceanic distances. One probable source is the small but persistent fishing fleet using the area. PMID:23953893

  11. A Transnational World Fractured but Not Forgotten: British West Indian Migration to the Colombian Islands of San Andrés and Providence

    Directory of Open Access Journals (Sweden)

    Sharika Crawford

    2011-06-01

    Full Text Available This article examines British West Indian migration to the Colombian archipelago of San Andrés and Providence in the late nineteenth to early twentieth century. While the United Fruit plantations, Panama Canal, oil fields in Venezuela, and railroad projects in Central America generated a strong demand for a large West Indian workforce, no such development took place on San Andrés and Providence. As a result, the profile of West Indian migration looks different than to the Spanish-speaking circum-Caribbean, with more professionals and merchants and fewer unskilled laborers. In the absence of mass migration, there was less hostility toward West Indian newcomers to San Andrés and Providence islands.

  15. Samarbejdets natur hos mennesket og andre aber

    DEFF Research Database (Denmark)

    Byrnit, Jill

    2015-01-01

    Omfattende grader af dele-adfærd og samarbejde hos mennesker finder sted overalt på jorden, men det er ikke et menneskeligt særtræk at være generøs og dele. Mange dyrearter deler med artsfæller, skønt måden, der deles på varierer mellem dyrearter. Igennem de sidste 20 år er der foretaget omfattende forskning omkring delings-adfærd hos andre aber end mennesket og forsøgene har givet os indsigt i flere forskellige ting omkring den menneskelige samarbejdsnatur i forhold til andre dyrs. Delingsadfærden hos mennesket antager former, der på nogle punkter er langt mere sammenlignelige med fjernere beslægtede aber end med menneskeaberne. Visse dyrearter viser sig desuden at klare sig mærkbart bedre end menneskeaberne i samarbejdsforsøg, hvor menneskelige signaler skal forstås. Især hunde udmærker sig ved dette og lader til at gå til opgaven med omtrent lige så få gnidninger som småbørn. Dette kan forklares ved, at der implicit i evnen til menneskeligt samarbejde ligger en motivation for at indgå i opgaveløsende relationer og en basal tillidsfuldhed omkring flokmedlemmer, som ikke er en selvfølgelighed for alle flokdyr, men som mennesket har fremavlet hos den tamme hund.

  17. The Idea of the Archipelago: Contemplating Island Relations

    Directory of Open Access Journals (Sweden)

    Elaine Stratford

    2013-05-01

    Full Text Available Creative, innovative, and timely research on islands and island futures is warranted and pressing, not least because island(ers are poorly served by established tropes of them as subordinate to continents or mainlands. Opportunities exist to provide a more thoroughgoing account of island life and island relations, and the seven papers in this special issue address that task. In works that consider islands in the Timor Sea, the Caribbean, the Pacific, Atlantic and Southern Oceans, and that span several different disciplinary frames—archival-historical, critical theoretical, literary, cultural, geopolitical, sociological and artistic—these papers evidence both the diversity of approach to thinking with the archipelago, and numerous points in common. Among the latter is an understanding that island relations are built on connection, assemblage, mobility, and multiplicity, and a commitment to critically examine the ways in which these entanglements affect and give effect to island life. The models of island relationality brought to light by this collective focus on the archipelago reveal new and diverse connections of island peoples with their physical and cultural environments, and with the world beyond; create spaces for growing resilience, association and engagement; and invite further study.

  18. Optimizing velocities and transports for complex coastal regions and archipelagos

    Science.gov (United States)

    Haley, Patrick J.; Agarwal, Arpit; Lermusiaux, Pierre F. J.

    2015-05-01

    We derive and apply a methodology for the initialization of velocity and transport fields in complex multiply-connected regions with multiscale dynamics. The result is initial fields that are consistent with observations, complex geometry and dynamics, and that can simulate the evolution of ocean processes without large spurious initial transients. A class of constrained weighted least squares optimizations is defined to best fit first-guess velocities while satisfying the complex bathymetry, coastline and divergence strong constraints. A weak constraint towards the minimum inter-island transports that are in accord with the first-guess velocities provides important velocity corrections in complex archipelagos. In the optimization weights, the minimum distance and vertical area between pairs of coasts are computed using a Fast Marching Method. Additional information on velocity and transports are included as strong or weak constraints. We apply our methodology around the Hawaiian islands of Kauai/Niihau, in the Taiwan/Kuroshio region and in the Philippines Archipelago. Comparisons with other common initialization strategies, among hindcasts from these initial conditions (ICs), and with independent in situ observations show that our optimization corrects transports, satisfies boundary conditions and redirects currents. Differences between the hindcasts from these different ICs are found to grow for at least 2-3 weeks. When compared to independent in situ observations, simulations from our optimized ICs are shown to have the smallest errors.

I artiklen beskriver jeg desuden, hvordan de forskellige videnskabelige discipliner historiske har udviklet sig, ligesom jeg beskriver, hvordan undervisningen på forskellige samfunds-videnskabelige uddannelser er tilrettelagt for at ruste de studerende til en fremtidige karriere inden for de, også temmeligt forskellige, hverv, som de færdige kandidater typisk bliver ansat i efter endt uddannelse. Det er mit håb, at denne artikels beskrivelse af forskellene mellem juraen og andre human- og samfundsvidenskaber kan bidrage til, at jurastuderende får en bedre forståelse for juraens særlige beskaffenhed – herunder forstår, hvordan juraen skiller sig ud fra andre samfundsvidenskaber.

More precisely, in this case we show that $\\psi$ is complete intersection at $\\phi^{-1}(\\fn)$ for every prime ideal $\\fn$ of $S$. Using these results, we describe all algebra retracts $S\\to R\\to S$ for which the $S$-algebra $Tor^R(S,S)$ is finitely generated.

  14. Seismic Hazard Maps for the Maltese Archipelago: Preliminary Results

    Science.gov (United States)

    D'Amico, S.; Panzera, F.; Galea, P. M.

    2013-12-01

    The Maltese islands form an archipelago of three major islands lying in the Sicily channel at about 140 km south of Sicily and 300 km north of Libya. So far very few investigations have been carried out on seismicity around the Maltese islands and no maps of seismic hazard for the archipelago are available. Assessing the seismic hazard for the region is currently of prime interest for the near-future development of industrial and touristic facilities as well as for urban expansion. A culture of seismic risk awareness has never really been developed in the country, and the public perception is that the islands are relatively safe, and that any earthquake phenomena are mild and infrequent. However, the Archipelago has been struck by several moderate/large events. Although recent constructions of a certain structural and strategic importance have been built according to high engineering standards, the same probably cannot be said for all residential buildings, many higher than 3 storeys, which have mushroomed rapidly in recent years. Such buildings are mostly of unreinforced masonry, with heavy concrete floor slabs, which are known to be highly vulnerable to even moderate ground shaking. We can surely state that in this context planning and design should be based on available national hazard maps. Unfortunately, these kinds of maps are not available for the Maltese islands. In this paper we attempt to compute a first and preliminary probabilistic seismic hazard assessment of the Maltese islands in terms of Peak Ground Acceleration (PGA) and Spectral Acceleration (SA) at different periods. Seismic hazard has been computed using the Esteva-Cornell (1968) approach which is the most widely utilized probabilistic method. It is a zone-dependent approach: seismotectonic and geological data are used coupled with earthquake catalogues to identify seismogenic zones within which earthquakes occur at certain rates. Therefore the earthquake catalogues can be reduced to the activity rate, the b-value of the Gutenberg-Richter relationship and an estimate of the maximum magnitude. In this article we also defined a new seismogenic zones in the central Mediterranean never considered before. In order to determine the ground motion parameters related to a specified probability of exceedance, the above statistical parameters are combined with ground motion prediction equations. Seismic hazard computations have been performed within the island boundaries. The preliminary maps for PGA distribution on rock site obtained for a 10% probability of exceedance shows values ranging between 0.09-0.18 g whereas, SA for 0.2, 04, 1.0 s show values of about 0.21-0.40 g, 0.14-0.24 g and 0.05-0.08 g respectively.

    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).

    Precise repeat airborne laser surveys were conducted over the major ice caps in the Canadian Arctic Archipelago in the spring of 1995 and 2000 in order to measure elevation changes in the region. Our measurements reveal thinning at lower elevations (below 1600 m) on most of the ice caps and glaciers but either very little change or thickening at higher elevations in the ice cap accumulation zones. Recent increases in precipitation in the area can account for the slight thickening where it was observed but not for the thinning at lower elevations. For the northern ice caps on the Queen Elizabeth Islands, thinning was generally <0.5 m yr-1, which is consistent with what would be expected from the warm temperature anomalies in the region for the 5 year period between surveys, and appears to be a continuation of a trend that began in the mid-1980s. Farther south, however, on the Barnes and Penny ice caps on Baffin Island, this thinning was much more pronounced at over 1 m yr-1 in the lower elevations. Here temperature anomalies were very small, and the thinning at low elevations far exceeds any associated enhanced ablation. The observations on Barnes, and perhaps Penny, are consistent with the idea that the observed thinning is part of a much longer term deglaciation, as has been previously suggested for Barnes ice cap. On the basis of the regional relationships between elevation and elevation change in our data, the 1995-2000 mass balance for the archipelago is estimated to be -25 km3 yr-1 of ice, which corresponds to a sea level increase of 0.064 mm yr-1. This places it among the more significant sources of eustatic sea level rise, though not as substantial as the Greenland ice sheet, Alaskan glaciers, or the Patagonian ice fields.

  7. Geochemistry of Isla Santa Cruz, Galapagos Archipelago, Ecuador

    The geochemistry of Galapagos volcanoes extends to more depleted signatures than most hotspots, and do not appear to follow a classical tholeiitic to alkalic evolutionary sequence (i.e., Hawaiian Islands). Thus far, no such predictable sequence has been identified for Galapagos volcanoes. Isla Santa Cruz is one of the oldest volcanoes in the archipelago. Bow (1979) identified 3 volcanic stages: the Platform Series, the Shield Series, and the Shield-Modifying stage. The Platform Series defines a liquid line of descent that differs from the one shared by the Shield and Shield-Modifying units, which are genetically related to each other. Within the Shield and Shield-Modifying lavas, K2O/TiO2 ratios reveal three distinct compositional sub-groups: 1) a MORB-like, low-K suite (0.25). These 3 sub-groups are geographically distributed across the island; the low-K suite is only in the north, whereas the alkaline suite constitutes the center highlands and the tholeiitic suite is on the eastern and northern flanks. Variations in La/Sm and Sm/Yb indicate that the magmas supplying the Shield and Shield-Modifying units were generated over a wide range of melting conditions: the alkaline suite melts were generated at the greatest depths and from the smallest melt fraction of the three suites, whereas the low-K suite originates from shallower, greater extents of melting; the tholeiitic lavas were generated at depths intermediate between the other 2 sub-groups. None of the lavas from Santa Cruz resemble material erupted at Fernandina volcano, the presumed center of the plume; radiogenic isotope ratios from previous research indicate that all Santa Cruz lavas are significantly more depleted than western Galapagos lavas. The ~1.2 Ma Platform Series is the most enriched of the Santa Cruz units. The Shield and Shield-Modifying lavas are all shifted towards more depleted signatures, approaching those of MORB, in terms of isotopic and incompatible trace element ratios and were erupted approximately 0.5 Ma. We consider several working hypotheses to explain these observations. First, lavas collected on Santa Cruz may be a late rejuvenescent phase, dominated by melting of the depleted upper mantle. Santa Cruz, however, is located too close to the plume center to have been generated via either of the prevailing rejuvenescence volcanism models (Bianco et al., 2005; Ribe & Christensen, 1999). An alternative hypothesis to explain the depleted signatures at Santa Cruz is that the lithosphere underlying the island is shallower than it is beneath the western archipelago, lengthening melt columns to shallower depths and allowing greater melt amounts of depleted upper mantle. Finally, it is possible that when Santa Cruz was forming ~3 million years ago, the plume center was located closer to the GSC, resulting in dilution of plume material by ridge-related magmas. In our presentation, we assess these models in light of new major and trace element data from fieldwork on Santa Cruz.

    The Aeolian archipelago (Italy) represents an approximately one-million-year-old volcanic arc related to the subduction of the Ionian oceanic plate beneath the Calabrian continental crust. The objective of this work is to develop a better understanding of the regional structure of the whole archipelago. The crustal structure under each station was obtained applying P-receiver function technique to the teleseismic P-coda data recorded by the broadband seismic network (10 stations) installed by the Istituto Nazionale di Geofisica e Volcanologia (INGV-CT). Receiver functions were computed by using the Extended-Time Multitaper Frequency Domain Cross-Correlation Receiver Function (ET-MTRF) method. The preliminary results suggest a very similar listhospheric structure below all the islands of the Aeolian archipelago, with the exception of Stromboli. The boundary between the subducting ocean crust of the Ionian plate and the Thyrrenian mantle is clearly observed below all the stations.

  11. A conservation strategy in San Andres Island: school projects and values in environmental education

    International Nuclear Information System (INIS)

    With the scope of showing and preserving an island endangered species, the Swanka turtle, a campaign and an environmental education program were conducted. The campaign consisted in showing the species to the community, its characteristics and its threats, through mass media and visits to different local schools. The environmental education program was carried out through a Scholar Environmental Project, which consisted on the conformation of an environmental group, where cognitive, attitudinal and participative aspects were worked together. Using a constrictive methodology the children developed some knowledge about the species and Its habitats. The scope was that they modified attitudes and behaviors towards situations that contribute to environmental damage; the reinforcement of values was the central point during all the activities. The knowledge gained by the pupils and the observed changes on their attitudes and participation show the positive results that arise when the action of environmental education focuses on the people and not the resources that are to be preserved

    Full Text Available Mangrove forest is an important ecosystem that provides many services, but in Panama, as in other countries, they are under threat due to a variety of human activities. Nowadays, large areas of mangroves continue to be lost without been described and lack of management strategies. This study focused on the mangrove structure in the two largest islands, Isla del Rey and Isla San Jose, of Las Perlas Archipelago (LPA, Pacific Panama. Assessment of Landsat satellite imagery revealed loss of mangroves in the LPA of 965ha in the period 1974-1986, and 248ha in the period 1986-2000. The majority of the loss (>77% from the two study islands was due to timber extraction and agricultural development. In May 2006, permanent plots following the CARICOMP protocol were established at two sites on Isla del Rey (R1 and R2 and one site on Isla San Jose (SJ where standardized metrics such as species, height and diameter at breast height of adult trees and seedlings were recorded. Forest structure differed at the three sites, although R1 and R2 were most similar. At R1, Laguncularia racemosa was the important species and R2 was dominated by Pelliciera rhizophorae. Examination of the forest structure and classified imagery indicated that these sites are spatially dynamic and appear to be rejuvenating. The forest structure would indicate that the sites have been growth-limited previously by human activities and possibly by other factors. SJ was dominated by Rhizophora mangle and appears to have a mature forest with large adult trees and few seedlings. It does not appear to have shown the same extent of spatial regrowth as the other two sites between 1986 and 2000 and is relatively static. The establishment of permanent plots and monitoring will be useful as part of the management plan, as the LPA shows a variety of mangrove structures and could be subject to further coastal development.

  20. Earthquakes: San Francisco

    Science.gov (United States)

    The prediction of earthquakes may be inexact, but it is vital, especially when large cities such as San Francisco or Los Angeles are threatened. The San Andreas Fault and two other faults, the Heyward and Calaveras faults, all have the potential to deliver a massive earthquake to the San Francisco Bay area. In this video segment, a seismologist explains the historical pattern of seismic activity in the Bay area, and how this information may be used to predict the location and timing of San Francisco's next big earthquake. The segment is three minutes twenty-eight seconds in length. A background essay and discussion questions are included.

    2007-03-01

    This paper focuses on the invasion by Turbinaria ornata (a brown algae) in the Tuamotu archipelago, French Polynesia [(5-35°S)/(200-230°E)]. Prior to 1980, this alga existed only in the Society and Austral archipelagoes. Between 1985 and 1990, it began to appear in the southern and northern parts of the Tuamotu archipelago. Genetic analyses have been shown not to be appropriate in determining the origin of this algae population. This study investigated the possible ocean drift of floating aggregates of algae. Ocean currents were calculated from satellite data from 1993 to 2001. Their spatial variations as well as their seasonal and interannual variations are described along with calculated drift trajectories. While it was found that mean currents cannot directly transport algae from the Society and Austral archipelagoes to the Tuamotu, the large interannual changes during the El Niño-Southern Oscillation phenomenon produce current reversals that are strong enough to create a transport pathway in a short enough time to allow their survival.

    Detailed aerosol chemical predictions by a carefully designed model system (i.e. PMCAMx, WRF, GEOS-CHEM), along with airborne and ground-based observations, are presented and analyzed over a wide domain covering the Aegean Archipelago. The studied period is ten successive days during the summer of 2011, characterized by the most frequent prevailing wind conditions (Etesian regime). The submicron aerosol load in the lower troposphere above the Archipelago (organics (2.3 and 4.4 ?g m-3) and ammonium (1.5 and 1.7 ?g m-3). Aerosol concentrations smoothly decline aloft, reaching lower values (chloride, elemental carbon, organic carbon and total PM10 mass concentration, indicating a satisfactory representation of the aerosol chemistry and precursors. Higher model discrepancies are confined to the highest (e.g. peak sulfate values) and lowest ends (e.g. nitrate) of the airborne aerosol mass size distribution, as well as in airborne organic concentrations (model underestimation around 50%). The latter is most probably related to the intense fire activity upwind the Archipelago (i.e. Balkan area and Black Sea coastline), which is not represented in the current model application. Overall, the model system shows the best agreement with observations under strong northeastern winds over the Archipelago and up to 2.2 km altitude. The activation of the chemical ageing of biogenic particles is suggested to be used for the aerosol chemistry module, when treating organics in a sufficient nitrogen and sulfate-rich environment, such as that over the Aegean basin. More than 70% of the predicted aerosol mass over the Aegean Archipelago during a representative Etesian episode is related to transport of aerosols and their precursors from outside the modeling domain.

    2015-01-01

    The occurrence of Varanus nebulosus (Gray, 1831) on Sumatra still remains open for debates, while records are limited, especially those associated with a voucher specimen. The oldest record of V. nebulosus that is associated with a specimen, i.e. SMF 11554 is dated back to 1889 and presumably from Bengal ("Bengalen"), which now lies around Bangladesh. The specimen is kept at Senckenberg Museum Frankfurt (SMF) in Germany. We collected specimens from two islands in the Riau Archipelago, just west of Sumatra and provided new distribution data for this protected species of Monitor lizard in Indonesia. The two recent records represent populations of V. nebulosus other than those already known in the literature and are among the closest known occurrences to Sumatra. We suggest that islands in the Riau Archipelago might have been the stepping stones for a historical dispersal of this species from mainland Southeast Asia and Singapore. PMID:25781125

    Full Text Available According to the special circumstances of the archipelago berth allocation, this paper proposes a model of Archipelago Berth Allocation Problem(ABAP, which considers numerous constraints such as the adaptability of berths, the depth of channels and the characteristics of ships. The objective of the problem is to minimize the sum of the handling time, waiting time and the sailing time in the port area of every ship. We introduce a formulation for solving this problem. Next, we present a Discrete Particle Swarm Optimization (DPSO to find an approximate solution for the problem. Some reasonable parameters of DPSO are determined through several tests. Finally, we set the Zhoushan Islands, China as an example. Computational experiments show that the algorithm is effective, and has achieved great results in terms of stability, convergence and running time.

    2007-11-01

    Full Text Available Political architecture differences have only seldom been explained in the political science literature by reference to physical factors like size and geography. Correcting this neglect while focusing on microstates and especially on archipelago geographies, this article aims at uncovering the impact of geographical non-contiguity on political institution-building. Three separate devices for power devolution - federalism, bicameralism and assembly quotas - perform as dependent variables, and the guiding hypothesis is, for each device, that the device is implemented among archipelagos to a higher extent than among contiguous entities. Although there are marked differences between devices, the findings in general support the belief that territorial non-contiguity is more likely to foster power devolution. The findings also survive controls that investigate the impact of contesting factors.

    2010-07-01

    As heavier crude oil reserves with higher asphaltene content are being more and more exploited, better understanding of asphaltenes becomes a necessity. Two models are proposed for the structure of asphaltenes, a topic of intense debate. The island model presents a large aromatic core with alkyl chains branching out. The archipelago model features multiple aromatic cores that are linked by alkyl chains, with possible alkyl chains branching out also. Several model compounds of the two structural models were studied using a variety of mass spectrometry (MS) methods: laser-induced acoustic desorption combined with electron ionization (LIAD/EI) MS, electrospray ionization (ESI) MS, and atmospheric pressure chemical ionization (APCI) MS. The observed fragmentation pathways were then compared to those of asphaltenes. Ions from island vs. archipelago model compounds showed distinct fragmentation characteristics, which will help in elucidating the complex molecular structure of asphaltenes.

A number of well-known 'ulama' came from this region, including Hamzah Fansuri, Shamsuddin al-Sumatrani, Nuruddin al-Raniri and Abdurrauf Singkel, who were extraordinarily productive in writing manuscripts, both for teaching and learning, and for other purposes. This manuscript writing tradition in Aceh then spread to a number of other areas in the Archipelago, such as Sulawesi, Java, and others. As a result, many Iocal manuscripts cat be found in these areas, which store knowledge specifically related to that area.Copyright (c 2014 by SDI. All right reserved.DOI: 10.15408/sdi.v11i2.621

    International Nuclear Information System (INIS)

    Full text : In Azerbaijan domestic and foreign companies hold wide-scaled prospecting operations in the central and southern parts of the Baku Archipelago and also in the Kobystan. There are hydrocarbons deposits determined in the northern of the Baku Archipelago. Deposits location by phase condition of hydrocarbons mainly follows the general regularity determined on many oil and gas bearing areas, pass of oil deposits to oil-gas and gas-condensate ones in the direction of increase of layers occurrence depth. There is also a considerable influence of a tectonic factor on the area location of deposits observed, expressing in difference of deposits height on different tectonic blocks and also there is an influence of a lithological factor. Results of works conducted on drilling and wells testing are still not enough for judging about lack of oil and gas content.

    Cox, Brett F.; Conyac, Martin D.

    1984-01-01

    The San Jacinto Wilderness, located in the San Jacinto Mountains approximately 4 to 11 mi west of Palm Springs, California, was investigated by field and laboratory studies. The wilderness contains no known mineral deposits and no evidence of past mineral production. Geologic, geochemical, and geophysical studies indicate that the San Jacinto Wilderness has little promise for the occurrence of mineral or energy resources. However, if future studies of plutonism and related processes of mineralization are conducted in the San Jacinto Mountains and vicinity, the metasedimentary rocks and bordering intrusive contacts in the south parcel of the wilderness might merit further examination. In particular, such future studies might further evaluate the origin and significance of minor stream-sediment geochemical anomalies for tungsten, cerium, and lanthanum detected in our panned-concentrate samples collected near the heads of Murray and Andreas Canyons.

    2009-01-01

    One of the greatest logicians of the twentieth century, Bertrand Russell, proposed that Economic power, unlike military power, is not primary, but derivative. Curiously, this conjecture has received scarce attention. This paper explores this theory. Our illustrative discourse tests this overlooked theory in the light of evolution: We model Homo evolution by sampling the past ?1000 years of cultural evolution in the Hawaiian archipelago. Our analysis concludes Russell's theory is true.

  11. Phylogeography of the prehensile-tailed skink Corucia zebrata on the Solomon Archipelago.

    Science.gov (United States)

    Hagen, Ingerid J; Donnellan, Stephen C; Bull, C Michael

    2012-06-01

    The biogeography of islands is often strongly influenced by prior geological events. Corucia zebrata (Squamata: Scincidae) is endemic to the geologically complex Solomon Archipelago in Northern Melanesia. We examined the level of divergence for different island populations of C. zebrata and discussed these patterns in light of Pleistocene land bridges, island isolation, and island age. Corucia zebrata was sampled from 14 locations across the Solomon Archipelago and sequenced at two mitochondrial genes (ND2 and ND4; 1697 bp in total) and four nuclear loci (rhodopsin, an unknown intron, AKAP9, and PTPN12). Measures of genetic divergence, analyses of genetic variation, and Bayesian phylogenetic inference were used and the data assessed in light of geological information. Populations of C. zebrata on separate islands were found to be genetically different from each other, with reciprocal monophyly on mitochondrial DNA. Populations on islands previously connected by Pleistocene land bridges were marginally less divergent from each other than from populations on other nearby but isolated islands. There are indications that C. zebrata has radiated across the eastern islands of the archipelago within the last 1-4 million years. Nuclear loci were not sufficiently informative to yield further information about the phylogeography of C. zebrata on the Solomon Archipelago. Analyses of the mitochondrial data suggest that dispersal between islands has been very limited and that there are barriers to gene flow within the major islands. Islands that have been isolated during the Pleistocene glacial cycles are somewhat divergent in their mitochondrial genotypes, however, isolation by distance (IBD) and recent colonization of isolated but geologically younger islands appear to have had stronger effects on the phylogeography of C. zebrata than the Pleistocene glacial cycles. This contrasts with patterns reported for avian taxa, and highlights the fact that biogeographic regions for island species cannot be directly extrapolated among taxa of differing dispersal ability.

  12. The volcanism of the Comores archipelago: mantle plume or lithosperic deformation?

    2015-04-01

    The development of the Comores archipelago in the Mozambique channel has been diversely interpreted since the 1970's. The two end-members causes are, on the one hand, a deep mantle plume that developed a hotspot track from the Seychelles Plateau to the Grande Comore, and, on the other hand, a lithospheric deformation that reactivated transform faults and controlled the magma path. The present work first surveys the sparse geological, geophysical and geochronological data available for this archipelago, re-evaluates the age of the magmatic activity and integrates this evolution at a regional scale. Combining realistic magma production rates, the volume of each edifice and the geochronological, it is showed that the magmatic activity started first in Mayotte about 20 Ma and second, almost simultaneously, in Anjouan, Mohéli and Grande Comore about 10 Ma ago. This magmatism, coeval with magmatic periods in areas surrounding the Mozambic channel, the southern East African rift and Madagascar, is organised in three periods since Late Oligocene. Magmatic provinces are now superimposed with seismic zones and graben structures. In consequence, the Comores archipelago is tentatively interpret as part of the East African rift rather than related to a distinct deep mantle plume.

  13. Aerosol chemistry above an extended Archipelago of the Eastern Mediterranean basin during strong northern winds

    Full Text Available Detailed aerosol chemical predictions by a carefully designed model system (i.e. PMCAMx, WRF, GEOS-CHEM, along with airborne and ground-based observations, are presented and analyzed over a wide domain covering the Aegean Archipelago. The studied period is ten successive days during the summer of 2011, characterized by the most frequent prevailing wind conditions (Etesian regime. The submicron aerosol load in the lower troposphere above the Archipelago (< 2.2 km altitude is homogenously enriched in sulfate (average modeled and measured submicron sulfate of 5.5 and 5.8 ?g m?3, respectively, followed by organics (2.3 and 4.4 ?g m?3 and ammonium (1.5 and 1.7 ?g m?3. Aerosol concentrations smoothly decline aloft, reaching lower values (< 1 ?g m?3 above 4.2 km altitude. Model performance is found good (according the selected evaluation criteria for sulfate, ammonium, chloride, elemental carbon, organic carbon and total PM10 mass concentration, indicating a satisfactory representation of the aerosol chemistry and precursors. Higher model discrepancies are confined to the highest (e.g. peak sulfate values and lowest ends (e.g. nitrate of the airborne aerosol mass size distribution, as well as in airborne organic concentrations (model underestimation around 50%. The latter is most probably related to the intense fire activity upwind the Archipelago (i.e. Balkan area and Black Sea coastline, which is not represented in the current model application. Overall, the model system shows the best agreement with observations under strong northeastern winds over the Archipelago and up to 2.2 km altitude. The activation of the chemical ageing of biogenic particles is suggested to be used for the aerosol chemistry module, when treating organics in a sufficient nitrogen and sulfate-rich environment, such as that over the Aegean basin. More than 70% of the predicted aerosol mass over the Aegean Archipelago during a representative Etesian episode is related to transport of aerosols and their precursors from outside the modeling domain.

  15. Toward a Theory of Island Pedogeography: Testing the driving forces for pedological assemblages in archipelagos of different origins

    Science.gov (United States)

    Ibáñez, Juan-José; Effland, William R.

    2011-12-01

    The Theory of Island Biogeography has been based on biodiversity studies and used as a powerful predictive tool. Currently pedogeography does not have a similar theoretical construct. Although island biodiversity and biological assemblages have been topics of widespread interest in biogeography, ecology and conservation biology, soil scientists have conducted few studies of pedodiversity and pedological assemblages in archipelagos. Several studies have demonstrated that pedodiversity and biodiversity patterns have striking similarities in very disparate environments and at different scales, thus it is possible to test for a similar construct of island pedogeography. We analyze similarities and differences in the pedosphere for three archipelagos with different origins: (i) oceanic-intra-plate chains islands (Hawaiian Islands), (ii) oceanic-intra-plate cluster islands (Canary Islands), (iii) non-marine land-bridge islands with volcanism associated with plate boundary conditions (Aegean Islands) and (iv) as a comparison, islands in a nonplate boundary setting (the British Isles). In the Canary Islands, we also compiled selected biological, physiographical, geological and climatic data for further analysis of pedodiversity, climatic diversity, geodiversity and biodiversity. Our pedogeographic analysis of the three archipelagos indicates archipelagos of varying origins contain different soil assemblages with plate tectonics as the main driving force. The similarities between pedodiversity and biodiversity are more remarkable than the differences. We tested the hypothesis that soil taxa distributions on island chains can be modelled as a power function similar to the species-area relationship (SAR) proposed by McArthur and Wilson for archipelagos. The SAR functional relationship has been widely corroborated in other biodiversity studies. The same patterns were obtained for pedodiversity and biodiversity in the British Isles, and after that in the Aegean Archipelago. In this study we show similar results in the Canary Islands. Furthermore, in the Canary Archipelago, a strong relationship exists between pedodiversity, biodiversity, climate diversity, habitat heterogeneity and relief. For the Hawaii Archipelago, we did not obtain a statistically significant relationship because soil inventories are not published for the smallest islands and islets. However, Hawaii does have a chronosequence from the older to the younger land units. Overall, the dynamics of the underlying plate tectonic hot spots seems to be the major driving force affecting the various diversity types. Based on these results, we suggest a theoretical proposal of "Island pedogeography" consistent and similar to the Theory of Island Biogeography, in view that the latter one also predicts the pedodiversity of soil assemblages in archipelagos. This study illustrates several possibilities for further research in soil geography.

  14. On Simplicial Commutative Algebras with Finite Andre-Quillen Homology

    CERN Document Server

    Turner, J M

    2003-01-01

    L. Avramov, following D. Quillen, posed a conjecture to the effect that if $R \\to A$ is a homomorphism of Noetherian rings then the Andr\\'e-Quillen homology on the category of A-modules satisfies: $D_{s}(A|R;-) = 0$ for $s\\gg 0$ implies $D_{s}(A|R;-) = 0$ for s>2. In an earlier paper, the author posed an extended version of this conjecture which considered A to be a simplicial commutative R-algebra with Noetherian homotopy such that the characteristic of $\\pi_{0}A$ is non-zero. In addition, a homotopy characterization of such algebras was described. The main goal of this paper is to develop a strategy for establishing this extended conjecture and provide a complete proof when R is Cohen-Macaulay of characteristic 2.

    Hvilken rolle spiller forældrene i børns mobning i skolen? Det er et emne, der igennem de senere år har været genstand for tiltagende opmærksomhed blandt både forskere, politikere, og forskellige børneretslige og skolepolitiske organisationer i Danmark. I takt med, at mobning blandt de danske skolebørn er blevet en stadig mere synlig problematik, er interessen for forældrenes andel i og ansvar for børns mobning også blevet skærpet. På tværs af interesseniveauer synes indgangen til problematikken at være den, at der findes kausale sammenhænge imellem børns sociale adfærd i skolen og deres forældres måder at opdrage og fungere som rollemodeller på. I min forskning på området har jeg taget et andet afsæt og har interesseret mig for, hvordan forældres positioner og mulige agens i dette felt betinges af og virker sammen med en række andre aktører på såvel lokale som på samfundsmæssige og politiske niveauer.

    The rise in sea level following the Last Glacial Maximum (LGM) radically altered pre-existing geography, pushing back the former shorelines. The effect of this eustatic change was particularly intense and dramatic in flat lands and shelves, such as the Sicilian Channel. High-resolution bathymetric maps and Chirp seismic profiles analyzed in this study show that the Sicilian Channel, now lying at depths rarely exceeding 150 m, has emerged several times during its geological history. The last emergence was during the Early Holocene, when kilometre-sized islands punctuated the north-western sector of the Sicilian Channel, the Adventure Plateau, forming a broad archipelago. Many of these islands, now located in water ranging in depth from - 10 to - 40 m, are composed of highly deformed Neogene sedimentary rocks (Talbot, Ante-Talbot, Nereo, and Pantelleria Vecchia banks), while others represent submarine Pleistocene volcanic edifices (Galatea, Anfitrite and Tetide banks). Sedimentary cover in all of these banks is virtually absent. High-resolution seismic profiles allowed the identification of post-LGM morphological markers associated with the marine transgression, some of which are characterized by melt water-pulses, as demonstrated by the presence of specific and distinct erosional features. Combining swath bathymetric data with the seismic profiles, we have generated two palaeogeographic maps of the former Adventure Archipelago at two specific time frames: (1) at the end of the Younger Dryas stadial (11,500 yr B.P., corresponding to a former sea level of - 60 m), and (2) at the end of the melt-water pulse 1B (11,200 yr B.P., corresponding to a former sea level of - 42 m). Maps clearly show that in just 300 years the geography of the archipelago has changed dramatically, so much so that some islands have disappeared and some have decreased by more than 80% of their pre-Younger Dryas size.

    Madeira forms a mid-Atlantic volcanic archipelago, whose economy is largely dependent on tourism. There, one can encounter different types of sand beach: natural basaltic, natural calcareous and artificial calcareous. Microbiological and mycological quality of the sand was analyzed in two different years. Bacterial indicators were detected in higher number in 2010 (36.7% of the samples) than in 2011 (9.1%). Mycological indicators were detected in a similar percentage of samples in 2010 (68.3%) and 2011 (75%), even though the total number of colonies detected in 2010 was much higher (827 in 41 samples) than in 2011 (427 in 66 samples). Enterococci and potentially pathogenic and allergenic fungi (particularly Penicillium sp.) were the most common indicators detected in both years. Candida sp. yeast was also commonly detected in the samples. The analysis of the 3rd quartile and maximum numbers of all indicators in samples showed that artificial beaches tend to be more contaminated than the natural ones. However, a significant difference between the variables was lacking. More monitoring data (number of bathers, sea birds, radiation intensity variation, and a greater number of samples) should be collected in order to confirm if these differences are significant. In general, the sand quality in the archipelago's beaches was good. As the sand may be a vector of diseases, an international common set of indicators and values and a compatible methodologies for assessing sand contamination, should be defined, in order to provide the bather's with an indication of beach sand quality, rather than only the water. - Highlights: • Microbial indicators were studied in the beach sands of Madeira archipelago. • Differences between years may be attributed to extreme weather. • Sand of artificial beaches has higher levels of microbial contamination. • Microbial analysis of the sand showed that the beaches have mainly good quality.

  19. Competing Notions of Diversity in Archipelago Tourism: Transport Logistics, Official Rhetoric and Inter-Island Rivalry in the Azores

    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.

    New Earth glaciation due to the Quaternary glaciation .epohami and modern climate. We distinguish four types of ice sheets: small glaciers and snowfields - a capacity of up to 100 m .; mountain-valley glaciation - up to 200 m .; net (transition to the coverslip) - up to 300 m. and glaciation (ice sheet) - up to 500 m. The archipelago is characterized by continuous permafrost raprosraneniem, which is located under the roof of the seasonally thawed layer at a depth of 0.1 to 3.2 m . The depth is increased by its lakes and man-made Taliko up to 35 m. The temperature of the permafrost Paleozoic sandstones and shales at a depth of 15 m. Reaches -3,5°; limestones and shales containing cryopeg it reaches -2,8° at a depth of 130 m. Power Cryolithozone on drilling data and calculations 265-280 m. The average temperature of ice sheets are formed depending on the type of ice, its cut and the power supply type and morphology of the surface. It differs from the temperature of the surrounding glacier rocks on 3-7° and is at a depth from the surface of the glacier 13-15 m .: -3 - -4,5°; at a depth of 30 m .: -2°. In the age of the Quaternary glaciation entire archipelago was covered with continental ice. Global warming has resulted in a reduction of its area by 25% In the northern part of the South Island there are snowfields and small lednichki. In the area of Matochkin Shar and further north to South Bay Sulmenova, found mainly hanging and cirque glaciers, severely degraded, and in most cases do not reach the sea. At the same time, in the South Bay and Sulmenova and a number of other areas there are powerful lobes were associated with the ice sheet interior of the North Island, and reaching the sea. In the west of the archipelago to reach the sea only a few branches of the Central ice sheet; in the eastern part of the North Island ice sheet breaks in the sea in the form of ice walls up to 400 meters. This part is called the Nordenskiöld glacier. The maximum ice thickness reaches 480 m. Observations of the authors of the glaciers of Novaya Zemlya (Hammer and Sickle, Rose et al.), Carried out in the monitor mode, the last 15 years show an intensive retreat from the shoreline inland archipelago and sharply higher flow of silt-pelitic material kut bays. Lithological changes the picture of the bottom of the bays, which causes certain biogenic transformation of ecosystems.

Main focus of this work was concentrated on the Early-Jurassic basalts widely represented on the Hooker island [1]. Together with the previous data [2] statistically reasonable paleomagnetic pole for the age boundary of 190 million years for the FJL is received (PLat.=62.4; PLon.=140.2; dp/dm=5.5/5.0; N=13). Paleomagnetic data allow to assume that the position of the FJL relative to the Europe in the Early Jurassic significantly differs from the present one. But to the Early Cretaceous it reached relative position very close to the presently observed [2]. We suggest that at least during Early-Middle Jurassic there was rifting processes between the North Barentz terrane (FJL and (may be) Svalbard) and the other part of the European tectonic domain. This rift was accompanied by shifting of the FLJ to the north-eastward on about 500 km. Also obtained paleomagnetic data agree with a hypothesis assuming that the FJL was passing over the Icelandic-Siberian hot spot during Jurassic-Cretaceous time: main paleolatitudes correspond to the Island's present latitude and the paleolatitude of the Siberian trapps. Paleomagnetic study of FJL has a reconnaissance character and cannot lead to any ultimate deductions as the data is obviously not enough. And further work on the basaltic covers of the archipelago seems to be very promising. Research was supported by grant RFBR 13-05-00177. 1. Karyakin Yu.V., Shipilov E.V.

  2. SANS. An introduction

    International Nuclear Information System (INIS)

    At the origin of the neutron scattering technique there is the interaction of thermal neutrons with the nuclei of atoms. In SANS experiments, as in other diffraction studies, one measures the scattered intensity, as a function of the direction of scattering. Density and concentration fluctuations, form factors, structure factors are presented. Data treatment and experimental aspects are also discussed. (K.A.)

    A common mode of speciation in oceanic islands is by anagenesis, wherein an immigrant arrives and through time transforms by mutation, recombination, and drift into a morphologically and genetically distinct species, with the new species accumulating a high level of genetic diversity. We investigate speciation in Drimys confertifolia, endemic to the two major islands of the Juan Fernández Archipelago, Chile, to determine genetic consequences of anagenesis, to examine relationships among populations of D. confertifolia and the continental species D. winteri and D. andina, and to test probable migration routes between the major islands. Population genetic analyses were conducted using AFLPs and nuclear microsatellites of 421 individuals from 42 populations from the Juan Fernández islands and the continent. Drimys confertifolia shows a wide genetic variation within populations on both islands, and values of genetic diversity within populations are similar to those found within populations of the continental progenitor. The genetic results are compatible with the hypothesis of high levels of genetic variation accumulating within anagenetically derived species in oceanic islands, and with the concept of little or no geographical partitioning of this variation over the landscape. Analysis of the probability of migration within the archipelago confirms colonization from the older island, Robinson Crusoe, to the younger island Alejandro Selkirk. PMID:25292282

    Enhanced mesoscale eddy activity northeast of the Hawaiian archipelago was investigated by using the high-pass filtered satellite altimetric sea surface height (SSH) data of the past 16 years. The level of eddy kinetic energy (EKE) shows significant interannual variations, which appear well correlated to the large-scale atmospheric wind forcing associated with the Pacific Decadal Oscillation index; the EKE levels in the area along the Subtropical Front zone in 1997-1998 and 2003-2005, for example, were three times as large as those in the low EKE years. Spectral analyses in the 3° latitude by 5° longitude subregions revealed the dominant mesoscale periods ranging from 90 days near 18°N to 180 days near 36°N. A 3?-layer quasi-geostrophic model constrained by World Ocean Atlas 2005 climatologies was used to explore instability of the regional circulation. The analysis shows a geographical match between baroclinic instability strength and the observed RMS SSH variability and a temporal match between seasonally varying instability strength and the observed seasonal EKE modulation, and suggests that baroclinic instability by the vertically sheared, regional mean circulation provides the energy source for the enhanced eddy variability northeast of the Hawaiian archipelago.

    Drosophila simulans and D. sechellia are sister species that serve as a model to study the evolution of reproductive isolation. While D. simulans is a human commensal that has spread all over the world, D. sechellia is restricted to the Seychelles archipelago and is found to breed exclusively on the toxic fruit of Morinda citrifolia. We surveyed the relative frequency of males from these two species in a variety of substrates found on five islands of the Seychelles archipelago. We sampled different fruits and found that putative D. simulans can be found in a variety of substrates, including, surprisingly, M. citrifolia. Putative D. sechellia was found preferentially on M. citrifolia fruits, but a small proportion was found in other substrates. Our survey also shows the existence of putative hybrid males in areas where D. simulans is present in Seychelles. The results from this field survey support the hypothesis of current interbreeding between these species in the central islands of Seychelles and open the possibility for fine measurements of admixture between these two Drosophila species to be made.

    Full Text Available This article discusses the challenges of developing a regional ocean prediction model for the Philippine Archipelago, a complex area in terms of geometry, bathymetry-dominated dynamics and variability, and strong local and remote wind forcing, where there are limited temporal and spatial ocean measurements. We used the Regional Ocean Modeling System (ROMS for real-time forecasting during the Philippines Experiment (2007–2009 observational program. The article focuses on the prediction experiments before and during the exploratory cruise period, June 6–July 3, 2007. The gathered observations were not available in real time, so the 4-Dimensional Variational (4D-Var data assimilation experiments were carried out in hindcast mode. The best estimate of ocean state (nowcast is determined by combining satellite-derived products for sea surface temperature and height, and subsurface temperature and salinity measurements from several hydrographic assets over a sequential five-day data assimilation window. The largest source of forecast uncertainty is from the prescribed lateral boundary conditions in the nearby Pacific Ocean, especially excessive salt flux. This result suggests that remote forcing and inflows from the Pacific are crucial for predicting ocean circulation in the Philippine Archipelago region. The lateral boundary conditions are derived from 1/12° global Hybrid Coordinate Ocean Model (HYCOM daily snapshots. The incremental, strong-constraint 4D-Var data assimilation successfully decreased temperature and salinity errors of the real-time, nonassimilative control forecast by 38% and 49%, respectively.

    The statistical characteristics of hourly mean wind speed data recorded at 16 weather stations located in the Canarian Archipelago are analyzed in this paper. As a result of this analysis we see that the typical two parameter Weibull wind speed distribution (W-pdf) does not accurately represent all wind regimes observed in that region. However, a Singly Truncated from below Normal Weibull mixture distribution (TNW-pdf) and a two component mixture Weibull distribution (WW-pdf) developed here do provide very good fits for both unimodal and bimodal wind speed frequency distributions observed in that region and offer less relative errors in determining the annual mean wind power density. The parameters of the distributions are estimated using the least squares method, which is resolved in this paper using the Levenberg-Marquardt algorithm. The suitability of the distributions is judged from the probability plot correlation coefficient plot R {sup 2}, adjusted for degrees of freedom. Based on the results obtained, we conclude that the two mixture distributions proposed here provide very flexible models for wind speed studies and can be applied in a widespread manner to represent the wind regimes in the Canarian archipelago and in other regions with similar characteristics. The TNW-pdf takes into account the frequency of null winds, whereas the WW-pdf and W-pdf do not. It can, therefore, better represent wind regimes with high percentages of null wind speeds. However, calculation of the TNW-pdf is markedly slower.

  9. Present situation and future prospects of electricity generation in Aegean Archipelago islands

    International Nuclear Information System (INIS)

    The Aegean Archipelago is a remote Hellenic area, including several hundreds of scattered islands of various sizes. In these islands more than 600,000 people are living mainly in small remote communities. The main economical activities of the islanders are apart from tourism, seafaring, fishery, agriculture and stock farming. One of the major problems of the area is the insufficient infrastructure, strongly related with the absence of an integrated and cost-effective electrification plan. In this context, the present work is concentrated on analyzing the present situation and demonstrating the future prospects of electricity generation in the Aegean Archipelago islands. For this purpose, one should first investigate the time evolution of the corresponding electricity generation parameters (i.e. annual electricity consumption, peak power demand, capacity factor, specific fuel consumption) for the last 30 years. Subsequently, the corresponding diesel and heavy-oil consumption along with the electricity production cost for every specific autonomous power station of the area are investigated. Special attention is paid in order to estimate the contribution of renewable energy sources (RES) in the energy balance of each island. Finally, an attempt is made to describe in brief the most realistic electricity production solutions available, including the operation of hybrid RES-based power plants in collaboration with appropriate energy storage facilities. Additionally, the idy storage facilities. Additionally, the idea of connecting the islands of the area with the mainland and interconnecting them is also taken into consideration

    The Saint Peter and Saint Paul Archipelago (SPSPA) are located close to the Equator in the Atlantic Ocean. The aim of this study was to assess the spatial variations in the copepod community abundance, and the biomass and production patterns of the three most abundant calanoid species in the SPSPA. Plankton samples were collected with a 300 µm mesh size net along four transects (north, east, south and west of the SPSPA), with four stations plotted in each transect. All transects exhibited a tendency toward a decrease in copepod density with increasing distance from the SPSPA, statistically proved in the North. Density varied from 3.33 to 182.18 ind.m-3, and differences were also found between the first perimeter (first circular distance band) and the others. The total biomass varied from 15.25 to 524.50 10-3 mg C m-3 and production from 1.19 to 22.04 10-3 mg C m-3d-1. The biomass and production of Undinula vulgaris (Dana, 1849), Acrocalanus longicornis Giesbrecht, 1888 and Calocalanus pavo (Dana, 1849) showed differences between some transects. A trend of declining biodiversity and production with increasing distance from archipelago was observed, suggesting that even small features like the SPSPA can affect the copepod community in tropical oligotrophic oceanic areas.

    Pollen analysis of continuous sediment cores from two lakes in the northern Chonos Archipelago (44°S) in southern Chile shows a complete postglacial record of vegetation change. The fossil records indicate that deglaciation was complete in the northern Chonos by at least 13,600 14C yr BP. Ericaceous heath and grassland persisted for more than 600 years after deglaciation under the influence of dry/cold climates and frequent burning. Nothofagus- Pilgerodendron- Podocarpus forest, with modern analogues in the southern Chonos Archipelago, was established across the northern islands by 12,400 14C yr BP under increasingly warm and wet climates. There is no evidence for a return to cooler climates during the Younger Dryas chronozone. The rise of Tepualia stipularis and Weinmannia trichosperma as important forest components between 10,600 and 6000 14C yr BP may be associated with climates that were warmer than present. The collapse of Pilgerodendron communities during this time may have been triggered by a combination of factors related to disturbance frequency including tephra deposition events, fire and climate change. After 6000 14C yr BP Pilgerodendron recovers and Nothofagus-Pilgerodendron-Tepualia forest persists until the present. European logging and burning activity may have increased the susceptibility of North Patagonian Rainforest to invasion by introduced species and to future collapse of the long-lived Pilgerodendron communities.

    Rainwater samples were collected at Zhoushan Archipelago in 2002 - 2003, 4 main anion concentrations (F-, Cl-, NO3-, SO4(2-)) and pH value of rainwater sample were determined. The concentration variation range and character were depicted. Principal component analysis (PCA) and factor analysis (FA) were used to acquire a further knowledge on the characteristics of anions and pH value. Distribution character of samples was clearly depicted in the new PC1-PC2 ordinate generated by orthogonal projection and the reasons that caused the outliers in samples were discussed. In order to get the latent variables which most distinguishably effect the sample distribution, data profiles were investigated by factor analysis: two latent variables were responsible for the sample distribution within sufficient analysis accuracy, SO4(2-) -NO3- factor (FA1), called as "anthropogenic factor", and Cl- (FA2), called as "marine factor", which corresponding to PC1 and PC2 in orthogonal projection respectively. Results from factor analysis were more practical than from orthogonal projection, that is, the reasons attributed the outlier sample distribution at Zhoushan Archipelago were ascribed into two latent variables: anthropogenic factor (SO4(2-) -NO3-) and marine factor (Cl-).

Thishas led to more epidemiological research into violence, and a stronger medical interest in the etiology and preventionof violence. However, epidemiological research on the prevalence of violence in different societies is stillmainly criminological in nature, being based on information about violence that has come to the attention of thepolice or processed in the courts. The study of the relationship between alcohol use and violent behaviour is alsopredominantly based on police and court materials, although an increasing number of emergency room andhospitalization studies have examined the role of alcohol in injuries caused by violence.There are two basic methodological approaches in the study of the relationship between alcohol use andviolence. The alcohol-involvement studies estimate the extent to which drinking by the offender or the victim waspresent in episodes of violence. Time trend studies and so-called natural experiments measure how rates of violentcrime covary with levels of alcohol consumption in a population. Generally, these studies indicate that alcohol useis a potent factor in determining the prevalence of violent behaviour in a society. However, there is no evidenceshowing that a significant part of alcohol-related violence is directly caused by the presence of alcohol in theorganism. Four types of conditional factors affecting the risk of violent behaviour after drinking are discussed: (1the nature of the alcohol factor, (2 characteristics of the individual drinker, (3 the socio-cultural context in whichdrinking occurs, and (4 situational factors.The epidemiological evidence for a relationship between violence and the use of other drugs is much morescattered. It is complicated by the fact that most drug users use more than one type of drug. When an illegalpsychoactive drug is implicated in violent behaviour, it is often also accompanied by alcohol use. Clinical andexperimental evidence shows that the risk of aggression and physical violence depends, in addition to the type ofdrug, on the amounts used, the method of application, the phase of acute intoxication, and the long-term pattern ofuse. However, the violence associated with the use of illegal drugs is perhaps most closely determined by thecharacteristics of an illegal economy. Rival criminal organizations manufacture, distribute and sell these drugs,and they use violence and threats as a means of regulating this economy. In addition, many drug users resort toviolent crime in an effort to secure the funds needed for their addiction.1996; 6 (1: 29-36.

    New Caledonia is a remote archipelago of the South-West Pacific, whose flora is rich, distinctive, and disharmonic. The interest of botanists has long been attracted by the spatio-temporal origin of this flora, but little attention has been paid to the modes of colonization and the diversification processes that have led to the archipelago's modern flora. To date, no explosive plant radiation has yet been highlighted for New Caledonia. A dated phylogenetic framework on the second richest New Caledonian genus--Psychotria s.l. and its allied genera (tribes Psychotrieae and Palicoureeae, Rubiaceae; ca. 85 species)--is provided in this study to explore its patterns of colonization and diversification in the archipelago. This study is based on a comprehensive species sampling, two nuclear and four plastid loci. Results show that New Caledonia was colonized four times by Psychotria and its allied genera during the Neogene long after its mid-Eocene re-emergence from the sea. The Pacific clade of Psychotrieae, one of the largest plant diversifications in the Pacific islands and the Indo-Pacific region, is absent from New Caledonia, possibly due to niche competition. Although the four lineages colonized New Caledonia relatively simultaneously during the Neogene, they express different evolutionary histories, as revealed by unevenness in species richness and net diversification rates. The genus Geophila has not diversified on New Caledonia, as a non-endemic single species has been documented in the archipelago. The genus Margaritopsis had a moderate level of diversification (four species) similar to that on other Pacific islands. The Psychotria clade NC1 appears to be a relictual lineage, which probably underwent a drastic extinction, with a narrow ecological habitat and dispersal limitations. The Psychotria clade NC2 is the largest and youngest New Caledonian plant radiation, and has undergone the fastest recorded diversification of any endemic lineage in the archipelago, and could be the result of a 'non-adaptive radiation', originating from Australian rainforests.

    Small-plastic beach debris from nine coastal locations throughout the Hawaiian Archipelago was analyzed. At each beach, replicate 20 l samples of sediment were collected, sieved for debris between 1 and 15 mm in size, sorted by type, counted and weighed. Small-plastic debris occurred on all of the beaches, but the greatest quantity was found at three of the most remote beaches on Midway Atoll and Moloka'i. Of the debris analyzed, 72% by weight was plastic. A total of 19100 pieces of plastic were collected from the nine beaches, 11% of which was pre-production plastic pellets. This study documents for the first time the presence of small-plastic debris on Hawaiian beaches and corroborates estimates of the abundance of plastics in the marine environment in the North Pacific.

    Four morphotypes are recognized in the photosymbiotic ascidian Didemnum molle in the Ryukyu Archipelago: three color morphs (white, dark gray, and brown) of small-type colonies and one large-type colony (white with gray patches). The genetic variation among these four morphotypes was investigated by constructing phylogenetic trees based on a 401-bp fragment of the cytochrome oxidase subunit I (COI) gene of 29 specimens collected from five islands (Okinawajima, Sesokojima, Ikeijima, Kumejima, and Ishigakijima). The results support the monophyly of the genus Didemnum and that of the four morphotypes of D. molle. Moreover, the phylogenetic trees discriminated four clades corresponding to each morphotype. The geographic differences of the sequences were much smaller than the differences among the morphotypes, suggesting that the four morphotypes in D. molle are discrete sibling species.

    Full Text Available Models of biogeographic processes can both enhance and inhibit our ability to ask questions that guide our understanding of patterns and processes. The two ‘traditional’ models of island biogeography, the Equilibrium Model and the Vicariance Model, raise important and insightful questions about relevant processes, but both fail to raise many crucial questions. An example involving the non-volant mammals of the Philippine archipelago shows that both models highlight some, but not all, relevant patterns and processes. The more recently proposed General Dynamic Model successfully combines many of the positive aspects of the two traditional models, but leaves some important questions unasked. We pose a number of questions here that may help guide further development of models of island biogeography.

    Full Text Available This article studies the metaphors in San?'?’s ghazals with the pivotal theme of love. The theoretical basis of the article is the theory of conceptual metaphor which has elevated metaphor from a mere rhetorical technique to a device of cogitation and cognition. At first, we present the principles of the theory considering the key words and terms coined by cognitive linguists and then give a detailed account of love metaphors in San?'?’s poems. Next, based on the thematic type, we categorize the metaphors into three groups: the metaphors which express a positive view of love, the ones which designate love as having negative characteristics and features and the double-edged metaphors. Subsequently, we analyze each group cognitively. The next entry is the aesthetic and rhetorical study of the metaphors under which we elucidate the main techniques as employed by San?'? , the innovator of the rhetoric of mystical ghazal.

This rocky reef system consists of a small group of coastal islands 5 km south off Ipanema Beach, Rio de Janeiro city, Brazil. A relatively diverse and disturbed fish community (99 species from 39 families was found in this archipelago. Two different visual census techniques were utilized and a large difference was observed in the number of species compared to other Brazilian reef sites. Trophic structure and biogeographical affinities are discussed. The absence of some reef fish species, mainly top predators, suggests severe environmental impact in this area and exhorts the Brazilian authorities to create a marine protected area. Results obtained in this study will serve to future environmental studies in Cagarras.A extensa costa brasileira abriga uma grande diversidade de peixes recifais.

Here, we report a pioneer study on the reef fish community composition of the Cagarras Archipelago. This rocky reef system consists of a small group of coastal islands 5 km south off Ipanema Beach, Rio de Janeiro city, Brazil. A [...] relatively diverse and disturbed fish community (99 species from 39 families) was found in this archipelago. Two different visual census techniques were utilized and a large difference was observed in the number of species compared to other Brazilian reef sites. Trophic structure and biogeographical affinities are discussed. The absence of some reef fish species, mainly top predators, suggests severe environmental impact in this area and exhorts the Brazilian authorities to create a marine protected area. Results obtained in this study will serve to future environmental studies in Cagarras.

  7. Unexpectedly high radioactivity burdens in ice-rafted sediments from the Canadian Arctic Archipelago

    International Nuclear Information System (INIS)

    Unexpectedly high specific activities of 137Cs (1800-2000 Bq kg-1 dry weight) have been detected in fine-grained sediments entrained in multi-year sea ice floes grounded in Resolute Bay near the center of the Northwest Passage through the Canadian Arctic Archipelago. These results are remarkable because: (1) the specific activities are about two orders of magnitude higher than average specific activities detected in previous studies of sea ice rafted sediments from the Arctic Ocean (2) two independent observations of these unexpectedly high specific activities were made several years apart (3) the sampling site is on the opposite side of the Arctic basin from potential radioactive sources such as disposal and weapons testing sites of the former Soviet Union and nuclear fuel reprocessing sites in western Europe, and (4) the closest compositional match to known geologic source regions is Banks Island, on the western edge of the Arctic Archipelago, although a smaller number of grains from one of the two samples were mineralogically matched to sediments in the Laptev Sea. Consequently, the sediments are probably not from a single distinct source and were likely mixed during sea ice transport. Coupled with previous observations of higher radionuclide specific activities in some sea ice rafted sediments relative to bottom sediments, these new observations indicate that comparatively high as well as variable radioactive contaminant burdens in ice raftedioactive contaminant burdens in ice rafted sediments must be common and geographically independent of proximity to known contaminant sources. The mechanisms that would facilitate these unexpected high radionuclide burdens in sea ice are not known and require additional study, as well as investigations of the implications for the transport and fate of contaminants in Arctic sea ice

  8. New data on Perkinsus mediterraneus in the Balearic Archipelago: locations and affected species.

    Perkinsus mediterraneus, a protozoan parasite that can cause perkinsosis (marine mollusc disease), was first detected in oysters Ostrea edulis from Mahon (Minorca, Balearic Islands, Spain) in 2004. Several years later it was also found in Andratx Harbour (Majorca, Balearic Islands) and in the Gulf of Manfredonia (Adriatic coast of Italy) in oyster populations. Since 2007, Perkinsus surveys have been conducted in different localities and shellfish species in the Balearic Archipelago. In the present work, we found P. mediterraneus in the Balearic Islands infecting oyster and other shellfish species. We describe infection with P. mediterraneus for the first time in Arca noae and Mimachlamys varia. The detection was carried out using Ray's fluid thioglycolate medium (RFTM), histology and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodologies. The internal transcribed spacer (ITS) region (including ITS1, 5.8S and ITS2) of P. mediterraneus ribosomal DNA was sequenced from infected bivalve gills (or from the body in Chamelea gallina) from Balearic Archipelago localities. Twelve haplotypes with a strong genetic similarity between them (97-100%) were observed in our samples. These data were completed with 12 more haplotypes from GenBank sequences. The phylogenetic relationship between Balearic P. mediterraneus haplotypes found in this study, those previously obtained in Mahon Harbour, and the Perkinsus spp. sequences available in GenBank clearly grouped the different Perkinsus spp. in distinct clades supported by strong bootstrap values. Moreover, these analyses detected different P. mediterraneus groups in O. edulis from Minorca Island. No abnormal mortalities or decline in populations were detected during the survey, except for C. gallina, which is also affected by Marteilia refringens. PMID:25392044

  11. Detailed geochemical survey data release for the San Andres-Oscura Mountains special study area, New Mexico

    International Nuclear Information System (INIS)

    The work reported here includes field data and the results of analyses for uranium and additional elements for each sample. This special study is a follow-up to the uranium reconnaissance previously conducted by Los Alamos in the surrounding Tularosa NTMS quadrangle as part of the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR). The HSSR program is part of the United States Department of Energy (DOE) National Uranium Resource Evaluation (NURE), which is designed to provide an improved estimate of the available information for industry use in the development and production of uranium resources. Each rock sample collected for this special study was crushed and the minus 100-mesh fraction was put into a prewashed 25-ml polyethylene vial and a clean 4-ml rabbit before undergoing analysis. The possibility exists of sample contamination with crusher alloys, especially in the rhyolite samples. The samples were analyzed for uranium and thorium as well as aluminum, antimony, arsenic, barium, beryllium, bismuth, cadmium, calcium, cerium, cesium, chlorine, chromium, cobalt, copper, dysprosium, europium, gold, hafnium, iron, lanthanum, lead, lithium, lutetium, magnesium, manganese, molybdenum, nickel, niobium, potassium, rubidium, samarium, scandium, selenium, silver, sodium, strontium, tantalum, terbium, tin, titanium, tungsten, vanadium, ytterbium, zinc, and zirconium. Descriptions of field and analytical methods can be found in Appendix II-A. Sample locations are pl in Appendix II-A. Sample locations are plotted on Plate I. All samples were analyzed for uranium by delayed neutron counting. Other elemental concentrations in samples were determined by neutron-activation analysis, x-ray fluorescence, and arc-source emission spectrography. Analytical results for samples are reported as parts per million

    Full Text Available Las islas Desventuradas (San Félix y San Ambrosio) y del Archipiélago de Juan Fernández (Robinson Crusoe y Alejandro Selkirk) son islas oceánicas de origen volcánico ubicadas en el Pacífico Sudeste, frente a Chile. Sobre la base de material recolectado desde 1997 hasta la fecha, revisiones de colecc [...] iones de las expediciones del R/V Anton Bruun y actualizaciones taxonómicas, la fauna de peces litorales del Archipélago de Juan Fernández y las islas Desventuradas tienen un total de 52 especies, con 41 y 43 especies, respectivamente. Los peces costeros endémicos de Juan Fernández son solamente cinco (12,2%) y tres son las especies registradas aquí como nuevas para las islas (Gymnothorax cf. obesus, Gnathophis sp., Suezichthys sp.). Las Desventuradas tienen solamente dos especies endémicas (4,6%) y cuatro son los nuevos registros (Scorpaenodes englerti, Maxillicosta reticulata, Suezichthys sp., Aseraggodes bahamondei). El reducido número de especies endémicas para Juan Fernández comparado con trabajos previos (15 especies) se debe a que muchas resultaron ser endémicas de ambos grupos de islas (22 especies = 42,3% total peces litorales), apoyando la propuesta que ambos grupos de islas debieran formar una sola unidad biogeográfica. La extensión oriental de la región Indo Pacífico Oeste para incluir la cordillera de Nazca, las islas Desventuradas y Juan Fernández encuentra apoyo en este trabajo. La afinidad zoogeográfica entre las Desventuradas y las islas del Pacífico Oeste (Isla de Pascua hasta Australia) incluye 16 especies, agregando cinco nuevos registros a listas anteriores. Filogenias de tres géneros señalan un centro de origen en el Pacífico Oeste, con uno o más eventos de dispersión hacia las islas Desventuradas y Juan Fernández. Este patrón de dispersión puede repetirse en otros siete géneros de pocas especies y relativamente restringidas en distribución. Solo una filogenia (Odontesthes) propone un origen continental con una dispersión hacia el Oeste, sin embargo otros tres géneros parecen tener este mismo patrón de dispersión. Abstract in english The Desventuradas Islands (San Félix and San Ambrosio) and Juan Fernández Archipelago (Robinson Crusoe and Alejandro Selkirk) are oceanic islands of volcanic origin located in the southeastern Pacific off Chile. Based on new material collected since 1997, revision of the R/V Anton Bruun expeditions [...] collections, and a taxonomic update, the coastal fish fauna of Juan Fernández Archipelago and Desventuradas Islands found a total of 52 species, with 41 and 43 species, respectively. The number of coastal fish species recorded herein as endemic for Juan Fernández is only five (12,2%) and three species are new records (Gymnothorax cf. obesus, Gnathophis sp., Suezichthys sp). The Desventuradas Islands have only two endemic species (4,6%) and four species are new records (Scorpaenodes englerti, Maxillicosta reticulata, Suezichthys sp., Aseraggodes bahamondei). The reduced number of endemic species for the Juan Fernández Islands as compared with previous accounts (15 species) is the result that more species were found to be endemic to both islands groups (22 species = 42,3% all coastal fishes), suggesting these two island groups should be considered a single biogeographic unit. The eastern extension of the Indo West Pacific Region to include the Nazca Ridge, Desventuradas and Juan Fernández Islands is supported herein. The zoogeographical affinities between Desventuradas and western Pacific Islands (Easter Island to Australia), includes 16 species, adding five new species to previous lists. Relationships of three genera indicate a Western Pacific origin with one or more dispersal events to the Desventuradas and Juan Fernández Islands. Another seven genera, with relatively few species and restricted distribution, may have this same pattern. Only one phylogenetic study indicates a continental origin with a westward dispersal (Odontesthes), however another three genera may have this same pattern of dispersal.

    The coastal and archipelago waters of the northern Baltic Sea are influenced by increasing eutrophication (significantly increasing temporal trends in nutrient availability). Increased nutrient levels and pelagic primary production have led to decreased transparency in the water body, increased plankton biomass, and increased amounts of filamentous algae. Large-scale and long-term (15-30 years) comparisons have shown that zoobenthic communities have changed significantly (altered species dive...

  1. An upper mantle seismic discontinuity beneath the Galápagos Archipelago and its implications for studies of the lithosphere-asthenosphere boundary

    An upper mantle seismic discontinuity (the Gutenberg or G discontinuity), at which shear wave velocity decreases with depth, has been mapped from S-to-p conversions in radial receiver functions recorded across the Galápagos Archipelago. The mean depth of the discontinuity is 91 ± 8 km beneath the southeastern archipelago and 72 ± 5 km beneath surrounding regions. The discontinuity appears deeper beneath the portion of the Nazca plate that we infer passed over the Galápagos mantle plume than elsewhere in the region. We equate the depth of the G discontinuity to the maximum depth extent of anhydrous melting, which forms an overlying layer of dehydrated and depleted mantle. We attribute areas of shallow discontinuity depth to the formation of the dehydrated layer near the Galápagos Spreading Center and areas of greater discontinuity depth to its modification over a mantle plume with an excess temperature of 115 ± 30°C. The G discontinuity lies within a high-seismic-velocity anomaly that we conclude forms by partial dehydration and a gradual but steady increase in seismic velocity with decreasing depth after upwelling mantle first encounters the solidus for volatile-bearing mantle material. At the depth of the solidus for anhydrous mantle material, removal of remaining water creates a sharp decrease in velocity with depth; this discontinuity may also mark a site of melt accumulation. Results from seismic imaging, the compositions of Galápagos lavas, and rare-earth-element concentrations across the archipelago require that mantle upwelling and partial melting occur over a broad region within the dehydrated and depleted layer. We conclude that the G discontinuity beneath the archipelago does not mark the boundary between rigid lithosphere and convecting asthenosphere.

  4. Archipelago-wide island restoration in the Galápagos Islands: reducing costs of invasive mammal eradication programs and reinvasion risk.

    Carrion, Victor; Donlan, C Josh; Campbell, Karl J; Lavoie, Christian; Cruz, Felipe

    2011-01-01

    Invasive alien mammals are the major driver of biodiversity loss and ecosystem degradation on islands. Over the past three decades, invasive mammal eradication from islands has become one of society's most powerful tools for preventing extinction of insular endemics and restoring insular ecosystems. As practitioners tackle larger islands for restoration, three factors will heavily influence success and outcomes: the degree of local support, the ability to mitigate for non-target impacts, and the ability to eradicate non-native species more cost-effectively. Investments in removing invasive species, however, must be weighed against the risk of reintroduction. One way to reduce reintroduction risks is to eradicate the target invasive species from an entire archipelago, and thus eliminate readily available sources. We illustrate the costs and benefits of this approach with the efforts to remove invasive goats from the Galápagos Islands. Project Isabela, the world's largest island restoration effort to date, removed >140,000 goats from >500,000 ha for a cost of US$10.5 million. Leveraging the capacity built during Project Isabela, and given that goat reintroductions have been common over the past decade, we implemented an archipelago-wide goat eradication strategy. Feral goats remain on three islands in the archipelago, and removal efforts are underway. Efforts on the Galápagos Islands demonstrate that for some species, island size is no longer the limiting factor with respect to eradication. Rather, bureaucratic processes, financing, political will, and stakeholder approval appear to be the new challenges. Eradication efforts have delivered a suite of biodiversity benefits that are in the process of revealing themselves. The costs of rectifying intentional reintroductions are high in terms of financial and human resources. Reducing the archipelago-wide goat density to low levels is a technical approach to reducing reintroduction risk in the short-term, and is being complemented with a longer-term social approach focused on education and governance.

    2015-04-01

    Within the scope of the two major international projects of long-term reanalysis for the 20th century coordinated by NOAA (Compo et al. 2011) and ECMWF (Hersbach et al. 2013) the IDL Institute from the University of Lisbon has digitized a large number of long-term stations records from Portugal and former Portuguese Colonies (Stickler et al. 2014). Recently we have finished the digitization of all precipitation values from Ponta Delgada (capital of the Azores archipelago) obtaining an uninterrupted precipitation monthly time series since 1864 and additionally an almost complete corresponding daily precipitation series, with the exception of some years (1864/1872; 1878/1879; 1888/1905; 1931; 1936 and 1938) for which only monthly values are available. Here, we present an annually, seasonally and daily resolution study of the rainfall regime in Ponta Delgada for the last 150 years and the North Atlantic Oscillation (NAO) influence over this precipitation regime. The distribution of precipitation presents an evident seasonal pattern, with a strong difference between the 'rainy season' (November/March) and the 'dry season' (June/August) with very little rainfall. April/May and September/October correspond to the transitional seasons. The mean annual rainfall in Ponta Delgada is approximately 910 mm and is accumulated (on average) in about 120 rainy days. The precipitation regime in Azores archipelago reveals large inter-annual and intra-annual variability and both have increased considerably in the last decades. The entire studied period (1865-2012) shows an increase in the rainfall conditions between a drier earlier period (1865-1938) and a wetter recent period (1939-2012). At daily resolution, we have used an approach based on different characteristics of rain spells (consecutive days with rainfall accumulation) that has been proved to be satisfactory for the analysis of the different parameters related to the rainfall regime (Kutiel and Trigo, 2014). This approach shows that the increase in precipitation is mainly due to more intense events which are reflected by higher rain spell yields (amount of precipitation) and rain spell intensity (amount of precipitation by day) values in the last decades. On the other hand, despite the fact that one of the most widely used NAO definitions includes sea level pressure from the Ponta Delgada station, its long-term impact on the Azores archipelago climate is not well established yet. Here, we assessed the NAO influence over the precipitation regime according to Spearman's rank correlation coefficients. Results show that the inter-annual variability of precipitation is largely modulated by the NAO mode. Correlation values of r=-0.90, r=-0.79 and r=-0.63 were obtained for years with positive (>1) or negative (

  10. Features of shoreline displacement in the Holocene of Franz josef Land Archipelago

    Changes in the global sea level after the LGM caused the significant alteration in relation of land and sea in Arctic. The rise of the sea level in Arctic was accompanied with present tectonic processes. Marine terraces are formed with the combination of eustatic sea level fluctuations and glacioisostatic uplift of the territory with the significant role of complicated tectonic block movements. There are nearly about 150 radiocarbon ages data for Franz-Josef Land archipelago now. The represented conclusions are a generalization of the published data and results of our field researches with series of new radiocarbon dates. We managed to collect valuable factual material during the Russian Arctic National Park expedition in 2012. The distinctions of post-glacial rise of different islands and peculiarities of Holocene deglaciation were identified with the help of marine terraces analysis. The altitude of the terraces with the same age on different islands exceeds 15 meters in some cases. However, analysis of the data suggests that the continuous series of raised beaches from 35 m a.s.l. formed during the last 10000 years. It is impossible to build up an univocal model of emergence isobases with the existing data. Alexandra Land Island was the special object of this investigation. The large beach ridge from Lunar Ice Cap to Kropotkina Ice Cap divides the island on two parts. The northern one is covered with marine sediments, whereas the southern - with glaciofluvial sediments with negligible areas of marine sediments. The difference between the terraces' ages of Alexandra Land on the Dezhneva Bay shore and the northern shore of island suggests that: 1) In the early Holocene the rate of the transgression exceeded the tectonic uplift of the territory; 2) Formation of the large central beach ridge occurred near 6700 years ago, the maximum marine limit in the Alexandra Land Island; 3) The rate of the tectonic rise of the territory exceeded the eustatic sea level rise in the period after 6700 years ago; 4) The formation of the large central beach ridge took place when the Ice Capes occupied less space than now. We express our gratitude to the administration of Russian Arctic National Park for providing access to FJL archipelago and organization of the expedition.

    The Indonesian Mixing program (INDOMIX) was designed to quantify the very strong mixing that transforms Pacific waters into homohaline Indonesian Waters in the Indonesian archipelago. The turbulent dissipation rates and associated mixing were estimated and analyzed using a multidisciplinary approach that combines physical and geochemical observations: 1) direct measurements of the dissipation using a microstructure profiler, 2) use of density-based fine-scale methods, and 3) study of the vertical distribution of natural radionuclides (radium isotopes and actinium-227). Data were collected at five contrasting stations within the Indonesian archipelago. Strong instabilities, inversions of the density profiles and a very strong water mass transformation were observed. A wide range of values is obtained for dissipation within [10-10, 10-4] W.kg-1 with spots of higher dissipation in the ocean interior correlated with a strong internal tide signal. Both Fine-scale and micro-scale methods allow us to identify very strong dissipation energy levels above the straits, ranging within [10-7, 10-4] W.kg-1, in contrast to lower values at stations far from generation sites. However, the dissipation in the interior water column for the station located in the center of Halmahera [10-9, 10-8] W.kg-1 is stronger than for the Banda station [10-11, 10-10] W.kg-1, which is further away from generation sites. The three approaches agree relatively well and provide Kz values ranging between 5 10-4 and 5 10-1 m2.s-1, except in the Banda Sea where values are similar to the ones found in the open ocean (10-6 m2.s-1). Kz values mainly increase toward the bottom, where stratification decreases. Surface mixing, at the base of the mixed layer is found to be still very strong with values within [10-4, 10-3 m2.s-1]. These results confirm the results of modelling studies, in which hypothesis of intensified subsurface mixing were made, a mixing that strongly modifies the whole tropical mean state and variability. We conclude, therefore, that climate models need to take into account this intensified ocean mixing to properly represent the mean state of the atmosphere and its climate variability.

    The Indonesian archipelago produces large internal tides dissipation in the thermocline. The recent Indonesian Mixing program (INDOMIX) has been designed to quantify this mixing using direct and indirect measure of the mixing.A wide range of values is obtained for dissipation within [10-8, 10-4] W/kg with spots of higher dissipation in the ocean interior correlated with a strong internal tide signal. Deduced Kz values are found between 510-4 to 5 10-1 m2/s, much more higher than open ocean values. Surface mixing, below the base of the mixed layer is found to be very strong above all straits, with values within [10-4, 10-3 m2/s]. Introduced in a model using an adapted parameterisation to the Indonesian archipelago, models show good agreement with the observations, where strong water mass transformation has been previously diagnosed. This additional mixing produce a ~0.5°C surface cooling and reduces by 20% the overlying deep convection. This improves both the amount and structure of the rainfall and weakens the wind convergence relaxes the equatorial Pacific trade winds and strengthens the winds along Java coast. These wind changes causes the thermocline to be deeper in the eastern equatorial Pacific and shallower in the eastern Indian Ocean. The El Nino Southern Oscillation (ENSO) amplitude is therefore slightly reduced while the Indian Ocean Dipole/Zonal Mode (IODZM) variability increases. IODZM precursors, related to ENSO events the preceding winter in this model, are also shown to be more efficient in promoting an IODZM thanks to an enhanced wind/thermocline coupling. The MJO is also improved in the model.Changes in the coupled system in response tidal mixing are as large as those found when closing the Indonesian Throughflow, emphasizing the key role of IA on the Indo-Pacific climate. This suggests that climate models need to take into account this intensified mixing to properly represent the mean state of the atmosphere and its climate variability.

    In the 1936 film, "San Francisco" Jeannette MacDonald sings the film's title song, which of course includes the Gus Kahn-penned lyric "San Francisco, welcome me home again/I'm not at home to go roaming no more." For those who might be pining for Baghdad by the Bay (or for images from the infamous earthquake in 1906), this online collection from the San Francisco Public Library will be most welcome. All told, the San Francisco Historical Photograph Collection contains more than 250,000 photographs of San Francisco and California, although not all of these photographs are available online here. Visitors should begin their voyage through these images by using their search engine, which allows them to search by photographer, subject index, or by date. Perhaps the most novel way to search the images is to look through the photos by using an interactive map of the entire city. Here visitors can find photographs of the historic Moulin Rouge nightclub in the historic Barbary Coast area, or move on over to Sutro Heights over on the Pacific Ocean. For those who might be feeling a bit less adventurous, there are a number of thematic collections, including "Picture This: Family Photographs of Everyday San Francisco".

  16. Spatial distribution of oxygen-18 and deuterium in stream waters across the Japanese archipelago

    Directory of Open Access Journals (Sweden)

    M. Katsuyama

    2014-09-01

    Full Text Available The spatial distribution of oxygen and hydrogen isotopic composition (?18O and ?2H of stream waters across Japan was clarified with a data set compiling sample data obtained from 1278 forest catchments during the summer of 2003. Both ?18O and ?2H values showed positive correlations with the mean annual air temperature and annual evapotranspiration, and negative correlations with latitude and elevation. Deuterium excess (d excess values in stream waters were higher on the Sea of Japan side, and lower on the Pacific Ocean side, of the Japanese archipelago. The d excess in precipitation was generally higher in winter and lower in summer in Japan. The Sea of Japan side experiences a great deal of snowfall, and seasonal changes in monthly precipitation are rather small. In contrast, the Pacific Ocean side experiences a large amount of rainfall during summer with low levels of precipitation during the winter. Therefore, the lower d excess in stream waters on the Pacific Ocean side reflects summer precipitation, and the higher values on the Sea of Japan side are affected by delayed recharge from snowmelt. The isoscapes of stream water connote not only spatially integrated but also temporally integrated isotope signals of precipitation, and provide a framework for addressing applied hydrological, ecological, or meteorological research questions at regional scales, such as the effects of climate change.

  17. Volatile organic compounds (VOCs) in air from Nisyros Island (Dodecanese Archipelago, Greece): Natural versus anthropogenic sources

    International Nuclear Information System (INIS)

    This study presents the chemical composition of VOCs in air and gas discharges collected at Nisyros Island (Dodecanese Archipelago, Greece). The main goals are i) to discriminate between natural and anthropogenic VOC sources and ii) to evaluate their impact on local air quality. Up to 63 different VOCs were recognized and quantitatively determined in 6 fumaroles and 19 air samples collected in the Lakki caldera, where fumarolic emissions are located, and the outer ring of the island, including the Mandraki village and the main harbor. Air samples from the crater area show significant concentrations of alkanes, alkenes, cyclic, aromatics, and S- and O-bearing heterocycles directly deriving from the hydrothermal system, as well as secondary O-bearing compounds from oxidation of primary VOCs. At Mandraki village, C6H6/?(methylated aromatics) and ?(linear)/?(branched) alkanes ratios 2O–CO2–H2S rich and discharge a large variety of VOC species. •Benzene/toluene ratios identify anthropogenic and natural sources of VOCs in air. •Aldehydes in air are produced by oxidation of alkanes and alkenes. •Geogenic furans and hydrogenated halocarbons in air are recalcitrant. -- Anthropogenic and natural VOCs in air are distinguished on the basis of aromatic, O-substituted, S-substituted and halogenated compounds

  18. Winds of time: Lessons from Utö in the Stockholm Archipelago, 1990–2001

    International Nuclear Information System (INIS)

    When investigating the success or failure of different wind power projects, it is essential to take into account how they were historically situated. This study focuses on attempts to develop wind power in an archipelago setting, at Utö in Sweden. It has been argued that the development of Swedish wind power slowed during the 1990s; by revisiting the early days of wind power, looking at resistance and support, and connecting success factors, this can be further investigated. Whereas earlier research pointed out institutional conditions and site-specific conditions as crucial for successful wind power development and acceptance, the picture can be made more complete by discussing how wind power projects are affected by time-specific historical conditions. In the case of Utö, these can partly be associated with a newly launched political support program that gave the project political legitimacy and added a “pioneering spirit” to the endeavor. Conversely, when wind power is not seen as “pioneering” or “experimental” any more, but as a mere industrial activity, other incentives may need to be offered to municipalities. -- Highlights: •When evaluating wind power projects, the historical context is important to complement the picture. •The case of Utö is tells important lessons of the Swedish early 1990s. •Success factors in this case: political legitimacy, local support, pioneering spirit, promising technology. •This wind power establishment was not seen as a threat to recreation or landscape. •Lessons for today: how to deal with socio-political acceptance when wind power becomes “industrial”

  19. Number of endemic and native plant species in the Galapagos Archipelago in relation to geographical parameters

    DEFF Research Database (Denmark)

    Willerslev, E.; Hansen, Anders J.

    2002-01-01

    By simple and multiple regression analyses we investigate updated species numbers of endemic and native vascular plants and seed plants in the Galapagos Archipelago in relation to geographical parameters. We find that the best models to describe species numbers are regression models with log-transformed species numbers as dependent and log-transformed modified area (i.e. area not covered with barren lava) as an independent variable. This holds both for total species number, for native species number, for endemic species number and for total number of seed plants as well as number of endemic seed plants. For the ratio between endemic and native species, modified area is also the major significant variable, but with a negative regression slope. Multiple regression models show that some isolation measures are significant contributors and may explain some of the residual variation, but their contribution to total explained variation is in general small. The results show that the species area relationships are different for native and endemic species. This is discussed in relation to classical island biogeographical models, and the concepts of radiative speciation. Udgivelsesdato: 2002

  20. Aesthetics and Empire: The Sense of Feminine Beauty in the Making of the US Imperial Archipelago

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available This article examines the “sense of beauty” in the United States imperial archipelago, composed of the island territories of Cuba, Hawai`i, Philippines, and Puerto Rico, all acquired in 1898. The theoretical connection among these two elements –aesthetics and empire– is provided by a revision of the concepts “economy of colonial desire” and “complex of visuality.” This paper analyzes the most advanced visual technology of the late nineteenth century: the mass- produced, printed photograph. In particular, it focuses upon the representations of feminine beauty as found the illustrated “new-possessions” books which described recent island acquisitions of the United States. The connections between aesthetics and the forms of governance in each territory will also be elucidated.Este artículo examina el “sentido de belleza” en el archipiélago imperial estadounidense, compuesto de los territorios isleños de Cuba, Hawai`i, Filipinas y Puerto Rico, todos adquiridos en 1898.

  1. Field observations of recent transgression on northern and eastern Melville Island, western Canadian Arctic Archipelago

    Science.gov (United States)

    Lajeunesse, Patrick; Hanson, Michelle A.

    2008-11-01

    After ~ 11,000 years of glacio-isostatically induced forced regression, geomorphological evidence indicates that the coastline of eastern Melville Island, western Canadian Arctic Archipelago, is now being transgressed. Recently developed coastal features associated with this transgression include: drowned gullies and small estuaries, barriers and lagoons, barrier islands, erosional notches, backstepping beaches, and drowned tundra vegetation and vehicle tracks dating from the 1970s. We mainly attribute this relative sea-level rise to the eastward migration of a peripheral crustal forebulge. Furthermore, the reported transgression also includes a component from recent eustatic sea-level rise during the 20th century. Recent earthquakes recorded in the Gustav-Lougheed Arch Seismic Zone located in Byam Martin Channel, 70 km east of Melville Island, suggest that neotectonics could also be involved in local relative sea-level adjustments. Other factors associated with global warming, especially the formation of an earlier shore-ice lead coupled with increased storm activity might also be responsible for some of the coastal changes. Our study indicates that the current zero isobase, separating areas of net transgression from those of net regression, is now located off the east coast of the island. Our field observations support recent glacio-isostatic modelling that shows the island is presently undergoing a transgression.

  2. Effects of fish stocking on ecosystem services: an overview and case study using the Stockholm Archipelago.

    Holmlund, Cecilia M; Hammer, Monica

    2004-06-01

    In this article, we focus on documented and possible effects of fish stocking in terms of ecosystem services. The increasing use of fish stocking between 1970 and 2000 in the semiurban setting of Stockholm archipelago, Sweden, is used as case study. The objective is to analyze this management practice from an ecosystem perspective, accounting for both the ecological and social context of releasing fish. The results show that enhancements of four native species (Salmo S. trutta, Salmo salar, Stizostedion lucioperca, and Anguilla anguilla) have dominated over new introductions of one nonnative species. (Oncorhynchus mykiss). The major objective has been to increase fish catches for local resource users. Involved stakeholders include three management agencies, one hydropower company, and several local sport fishing associations. Documented effects focus on recapture and production rates. However, our analysis suggests that additional positive or negative effects on biodiversity, food web dynamics, mobile links, or ecological information may also result, with possible consequences for the long-term provision of food, game, and aesthetic values. We conclude that a more adaptive and cooperative management approach could benefit from a deeper analysis of where, when, and what species is released, by whom, which stakeholders that use the fish and those ecosystem services the fish generate, and of the role of formal and informal institutions for monitoring and evaluating the success of releasing fish.

    2007-09-01

    The multi-parametric data observed by the Synthetic Aperture Radar (SAR) and the Moderate Image Scanning Radiometer (MODIS) were applied to analyze the water distribution in the Philippine Archipelago to build a new radar imaging model. The SAR provides information on the surface structure of the water affected by various phenomena such as currents, internal waves, swells, surface winds, rain falls, natural films, and so on. One difficult parameter among them is the natural film, which exhibits a damping effect to the surface roughness from breaking waves to capillary ones. The chlorophyll-a concentration observed by satellite sensors such as MODIS provide estimates of the standing stock of phytoplankton, which is considered as the parameter estimating the standing stock of zooplankton. The standing stocks of phytoplankton and zooplankton could be a proportional parameter to the amount of the natural film. In this study, a frequency dependent multi-parametric equation was proposed to rebuild the surface roughness with various parameters in the spectrum domain. Possible validation study was conducted with the relationship between the sum of power spectrum for certain frequency range with chlorophyll-a concentration on the Mindanao Sea and the Surigao Strait.

    2010-12-01

    More than 150 Global Positioning System (GPS) points across the Philippine archipelago have been installed by the Philippine Institute of Volcanology and Seismology (PHIVOLCS) and its collaborative partners. Results from the repeated GPS measurements conducted since 1996 up to the present on these points showed the following: (1) Based on uniform motion and velocity directions gathered from the GPS data, the Philippine Mobile Belt can generally be subdivided into three blocks: Central to Northern Luzon; Southern Luzon to Southern Visayas; Mindanao; (2) There is a significant internal deformation in the Philippine Mobile Belt as seen from variable velocities and azimuth directions relative to Eurasian plate. (3) Relative velocities across the Philippine Fault vary from 20 mm/yr to 29 mm/yr (vector azimuths from 322 deg to 4 deg) in Northern Luzon; 31.2 mm/yr to 53.3 mm/yr (300 deg to 310 deg) in Southern Luzon; 20.5 mm/yr to 25.1 mm/yr (305 deg to 347 deg) in Visayas and 14 mm/yr to 33 mm/yr (338 deg to 40 deg) in Mindanao. (4) There is an active extensional deformation (18 mm/yr) in Macolod Corridor while compressional deformation (24 mm/yr) exists between Southern Visayas and Mindanao. This reverse analogue of deformation is probably the result of the collision between Palawan and the Philippine Mobile Belt.

    During Late Wisconsinan glaciation the northern Laurentide and Innuitian ice sheets converged over the Canadian Arctic Archipelago. This ice sheet complex included several major ice streams, which constituted important dynamical components. Discharging into the Beaufort Sea and Baffin Bay, these ice streams were a primary control on ice sheet mass balance and ice age sedimentation on adjacent continental margins, including the Arctic Ocean basin. This study presents a new compilation of multibeam echosounder data, sub-bottom profiler data, radiocarbon ages, and marine sediment cores acquired primarily during regional surveys with the CCGS Amundsen. These data characterize the nature and thickness of seafloor sediments in Parry Channel (and many of its connecting channels) and Amundsen Gulf. When combined with the results of terrestrial geomorphological mapping of the adjacent islands, this dataset constrains the maximum extent, chronology, and behaviour of former ice streams in M'Clure Strait, Viscount Melville Sound, Lancaster Sound, and Amundsen Gulf. Importantly, these data highlight complex patterns of past ice stream flow during regional deglaciation. These results contribute to a better understanding of the causal mechanisms that occasioned retreat of the terrestrial and marine sectors of the Laurentide and Innuitian ice sheets. As well, this study helps to quantify past iceberg fluxes to the Arctic Ocean, which has implications for assessing past climate, and the origin of ice-rafted sediment and deep iceberg scours in the Arctic Ocean basin.

  7. Patch-Based Generative Shape Model and MDL Model Selection for Statistical Analysis of Archipelagos

    2010-01-01

    We propose a statistical generative shape model for archipelago-like structures. These kind of structures occur, for instance, in medical images, where our intention is to model the appearance and shapes of calcifications in x-ray radio graphs. The generative model is constructed by (1) learning a patch-based dictionary for possible shapes, (2) building up a time-homogeneous Markov model to model the neighbourhood correlations between the patches, and (3) automatic selection of the model complexity by the minimum description length principle. The generative shape model is proposed as a probability distribution of a binary image where the model is intended to facilitate sequential simulation. Our results show that a relatively simple model is able to generate structures visually similar to calcifications. Furthermore, we used the shape model as a shape prior in the statistical segmentation of calcifications, where the area overlap with the ground truth shapes improved significantly compared to the case where the prior was not used.

    Indonesia, an island nation linking mainland Asia with the Pacific world, hosts a wide range of linguistic, ethnic and genetic diversity. Despite the complexity of this cultural environment, genetic studies in Indonesia remain surprisingly sparse. Here, we report mitochondrial DNA (mtDNA) and associated Y-chromosome diversity for the largest cohort of Indonesians examined to date-2740 individuals from 70 communities spanning 12 islands across the breadth of the Indonesian archipelago. We reconstruct 50 000 years of population movements, from mitochondrial lineages reflecting the very earliest settlers in island southeast Asia, to Neolithic population dispersals. Historic contacts from Chinese, Indians, Arabs and Europeans comprise a noticeable fraction of Y-chromosome variation, but are not reflected in the maternally inherited mtDNA. While this historic immigration favored men, patterns of genetic diversity show that women moved more widely in earlier times. However, measures of population differentiation signal that Indonesian communities are trending away from the matri- or ambilocality of early Austronesian societies toward the more common practice of patrilocal residence today. Such sex-specific dispersal patterns remain even after correcting for the different mutation rates of mtDNA and the Y chromosome. This detailed palimpsest of Indonesian genetic diversity is a direct outcome of the region's complex history of immigration, transitory migrants and populations that have endured in situ since the region's first settlement.

    The main shield of Santa Cruz Island, at the center of the Galapagos Archipelago, is formed by series of thick fractured basaltic lava flows dissected by faults. The low-lying, extensive "basal" aquifer is the unique groundwater body currently identified on the island and is subjected to sea-water intrusion. Water abstracted from fault scarps in the coastal area and a 150 m deep borehole further inland is brackish and requires expensive desalination technique. Sea-water intrusion was mapped from electrical resistivity imaging with an airborne electromagnetic SkyTEM survey. At the regional and local scales, the fracturation network was described from satellite imagery and field measurements. A groundwater monitoring network was set up. The hydraulic properties of this heterogeneous geological environment was characterized by pumping tests and tidal signal propagation. In order to investigate recharge dynamics, a yearlong climatic monitoring was conducted in the humid highlands and compared to water level fluctuations in the deep borehole. Hydrodynamic properties were determined and recharge processes identified. Since cooling joints form a dense network of fractures, the aquifer is highly permeable. This facilitates sea-water intrusion and freshwater drainage to the ocean. Surprisingly, the highly conductive heterogeneities formed by fault scarps are not regional preferential groundwater flow paths. This is compatible with structural and geomorphological observations made at the ground surface where faults are seen to be discontinuous successions of "en echelon" tension fractures. A 2D numerical model will be used to determine the optimal location of a new borehole.

    Las Perlas Archipelago (LPA) is located off the Pacific Coast of Panama and was designated as a marine protected area (MPA) in 2007. This baseline study of the shallow and deeper sedimentary habitats of the islands partly informed the MPA designation. Ninety-two grab stations and twenty trawl stations were sampled. Sediment grab sample results were interpolated to produce a map that showed the area to be dominated by mud (1246 km2, 40%) and sand/shell sediments (780 km2, 25%). A total of 201 taxa were recorded and over 5800 individual specimens were processed, revealing that the sediments hold varying community compositions, with annelids being the dominant group (73%) followed by crustaceans (14%). Relationships were evident between community, feeding guilds, and sediment types, which give an indication of communities that can be expected in similar sediments in other areas of the Tropical Eastern Pacific. A study of this scale and level of detail is rare for this biogeographic region and provides a valuable, comprehensive appreciation of the LPA's benthos. PMID:19081116

  11. Restrictions on the compatibility of equipment in archipelago countries: PERTAMINA experiences in Indonesia

    International Nuclear Information System (INIS)

    Being an archipelago state, the sea area of Indonesia is four times larger than its land area. Oil and natural gas play significant roles in the country's economic development. These activities at sea are showing signs of increasing, inevitably rendering the marine environment and living resources vulnerable to oil spills. Accidents, particularly grounding and collision occurrences in Malacca and the Singapore Straits sea lanes pose imminent threats. At PERTAMINA, the state-owned oil, gas and geothermal enterprise, oil spill contingency planning is entrusted to the Corporate Center for Environment Protection, Health and Safety. Marine activities are managed under the Directorate of Shipping, Harbour and Communication. In this paper oil spill response planning and coordination activities, which are based on the International Petroleum Industry Environmental Conservation Association (IPIECA) tiered preparedness concept, are described. The tiered preparedness concept addresses the limited availability of equipment, and incorporates specific response plans for each type of spill scenario (e.g. passing tanker, loading/unloading ship at terminal, major inland spill, etc), for each area of operation. It also specifies the type of equipment that must be available in the area to respond to the type of spill (using the concept of maximum credible spill in each case) that may occur in that area. 5 figs

  12. 137Cs dating of laminated sediments in Swedish archipelago areas of the Baltic Sea

    International Nuclear Information System (INIS)

    In deep off-shore areas of the Baltic Sea, sediment accumulation rates are typically on the order of one or a few millimeters per year, and even less in consolidated sediments, based on laming counts and radiometric dating. In lacustrine and marine basins, the highest sedimentation rates are usually found in the deepest part, since sediments and associated contaminants are known to be gradually 'focused' from shallow to deep areas by resuspension. Accordingly, net sedimentation in coastal areas is usually low or absent due to strong erosion forces. On the other hand, coastal sediments are likely to be important in controlling the fate and turnover of contaminants that are released into coastal waters. Since little is known about the turnover of coastal sediments, in particular for heterogeneous semi-enclosed areas such as the Baltic archipelagos, a study of sediment accumulation rates has been initaited, with a focus on areas where erosion is likely to be minimal. The study is part of a project focusing on the relationship between eutrophication and contaminant cycling (EUCON). 88 sediment cores were collected during summer 1996 from accumulation bottoms of 18 more or less protected bays in archipalgo areas along the swedish coast of the Baltic Sea

  13. Feeding Habits of Introduced Black Rats, Rattus rattus, in Nesting Colonies of Galapagos Petrel on San Cristóbal Island, Galapagos.

    Introduced rodents are responsible for ecosystem changes in islands around the world. In the Galapagos archipelago, their effects on the native flora and fauna are adverse, including the extinction of endemic rodents in some islands and the reduction in the reproductive success of the Galapagos petrel (Pterodroma phaeopygia) in its nesting zones. Understanding the feeding behavior of introduced rodents and their trophic interactions with native and non-native species on islands, can assist in the design of management strategies and conservation plans of invasive and endemic species respectively. Four petrel nesting colonies were monitored during June 2013 on San Cristóbal Island (El Plátano, El Junco, San Joaquín, and La Comuna). The feeding habits of black rats were evaluated by analyzing stomach contents and stable isotopes in hair. Three species of introduced rodents were captured. R. rattus was the most abundant at all sites (n=43, capture success (CS) = 55.8%), followed by the house mouse, Mus musculus (n = 17, CS = 37.8%), and the Norwegian rat, R. norvegicus (n = 4, CS = 4.5%), captured only at La Comuna. The omnivorous black rat ate mostly plants (98%) and arthropods (2%). Intact seeds of Miconia robinsoniana were the main food at all sites (relative abundance=72.1%, present in 95% of the analyzed stomachs), showing the black rats' possible role in the archipelago as endemic seed dispersers. There was no evidence of petrel's intake; however, its possible consumption is not discarded at all. The ?15N and ?13C analysis corroborated the primarily herbivorous diet of black rats. The isotopic signatures of the three rodent species reflect the inter- and intra-specific differential use of food resources. Black rat showed a wider diet in La Comuna, which was related to a lower availability of its primary prey and its ability to adapt to the available resources in its habitat. PMID:25984724

  14. Circulation in the Philippine Archipelago Simulated by 1/12° and 1/25° Global HYCOM and EAS NCOM

    Full Text Available Three ocean models, 1/25° global HYbrid Coordinate Ocean Model (HYCOM, 1/12° global HYCOM, and EAS NCOM nested in global NCOM, were used to provide a global context for simulation of the circulation within the Philippine Archipelago as part of the Philippines Experiment (PhilEx. The Philippine Archipelago provides two significant secondary routes for both the Indonesian throughflow and the western boundary current of the Pacific northern tropical gyre. The deeper route enters the archipelago from the north through Mindoro Strait, after passing through Luzon Strait and the South China Sea. The second route enters directly from the Pacific via the shallow Surigao Strait and passes through Dipolog Strait downstream of the Bohol Sea. Both pathways exit via Sibutu Passage and the adjacent Sulu Archipelago along the southern edge of the Sulu Sea, and both are deeper than the pathway into the Indonesian Archipelago via Karimata Strait in the Java Sea. Within the Philippine Archipelago, these pathways make the dominant contribution to the mean circulation and much of its variability, while their outflow contributes to the flow through Makassar Strait, the primary conduit of the Indonesian throughflow, at all depths above the Sibutu Passage sill. Because of the narrow straits and small interior seas, the simulations are very sensitive to model resolution (4.4 km in 1/25° global HYCOM, 8.7 km in 1/12° global HYCOM, and 9.6 km in EAS NCOM in this latitude range and to topographic errors, especially sill depths. The model simulations for 2004 and 2008 (the latter the central year of the PhilEx observational program show extreme opposite anomalous years with anomalously strong southward Mindoro transport in 2004 and mean northward transport in 2008, but with little effect on the Surigao-Dipolog transport. Satellite altimetry verified the associated HYCOM sea surface height anomalies in the western tropical Pacific and the South China Sea during these extreme years. A 15-month (December 2007–March 2009 PhilEx mooring in Mindoro Strait measured velocity nearly top to bottom at a location close to the sill. The 1/12° global HYCOM, which showed the strongest flow above 200 m lay west of the mooring, was used to adjust a Mindoro transport estimate from the mooring data for cross-sectional distribution of the velocity, giving 0.24 Sv northward over the anomalous observational period. The results from the observational period were then used to adjust the 2004–2009 model transport, giving a mean of 0.95 Sv southward. The 1/25° global HYCOM simulated the observed four-layer flow in Dipolog Strait and the vigorous and persistent cyclonic gyre in the western Bohol Sea, observed during all four PhilEx cruises and in ocean color imagery. This gyre was poorly simulated by the two models with ~ 9 km resolution. Finally, a 1/12° global HYCOM simulation with tides generated the hydrostatic aspect of the internal tides within the Philippine Archipelago, including a strong internal tidal beam initiated at Sibutu Passage and observed crossing the Sulu Sea.

  19. Facies, Stratigraphic and Depositional Model of the Sediments in the Abrolhos Archipelago (Bahia, BRAZIL)

    Matte, R. R.; Zambonato, E. E.

    2012-04-01

    Located in the Mucuri Basin on the continental shelf of southern Bahia state, northeast Brazil, about 70 km from the city of Caravelas,the Abrolhos archipelago is made up of five islands; Santa Barbara, Redonda, Siriba, Guarita and Sueste. The exhumed sediments in the Abrolhos archipelago are a rare record of the turbidite systems which fill the Brazilian Atlantic Basin, and are probably an unprecedented example of a plataform turbidite system (Dr. Mutti, personal communication). Despite the limited area, the outcrops display a wide facies variation produced by different depositional processes, and also allow for the observation of the layer geometries. Associated with such sedimentary rocks, the Abrolhos Volcanic Complex belongs stratigraphically to the Abrolhos Formation. These igneous rocks were dated by the Ar / Ar method, with ages ranging from 60 to 40 My, placing such Volcanic Complex between the Paleocene and Eocene. The sedimentary section is best exposed in the Santa Barbara and Redonda islands and altogether it is 70 m thick. The measured vertical sections show a good stratigraphic correlation between the rocks of the western portion of the first island and those of Redonda Island. However, there is no correlation between the eastern and western portions of Santa Barbara Island, since they are very likely interrupted by the igneous intrusion and possibly by faulting. The sedimentary stack consists of deposits with alternated regressive and transgressive episodes interpreted as high frequency sequences. The coarse facies, sandstones and conglomerates, with abrupt or erosive bases record regressive phases. On the other hand, finer sandstones and siltstones facies, which are partly bioturbated, correspond to phases of a little sediment supply. In the central and eastern portions of Santa Barbara Island, there is a trend of progradational stacking, while both in the western portion of Santa Barbara and in Redonda islands an agradational trend is observed. The predominance of layers with tabular geometry, characteristic of turbidite lobes, the presence of hummocky stratification, trace fossils typical of shallow water (Ophiomorphs and Thalassinoides), all associated with the occurrence of the carbonaceous material as well as plant fragments suggest a deltaic/ plataform depositional context. Textural features and sedimentary structures observed in the conglomerates and sandstones show the action of gravitational flows of high and low density. The fine interlaminated sandstones and siltstones later deformed as slumps or slides, and conglomerates with oriented clasts indicate, respectively, mass movements and action of debris flow. Conglomeratic lags levels record a bypass phenomenon. There are no biostratigraphic data in these studied outcrops. However, petrographic analyses revealed the presence of fragments of igneous rocks (basalts and diabases) in both sandstones and conglomerates, suggesting a relative contemporaneity between igneous activity and sediment deposition. Futhermore, petrographic analyses also found poor permo-porous conditions in the reservoirs due to the presence of fragments of volcanic rocks and the abundance of intraclasts / pseudomatrix.

[...] Plankton samples were collected with a 300 µm mesh size net along four transects (north, east, south and west of the SPSPA), with four stations plotted in each transect. All transects exhibited a tendency toward a decrease in copepod density with increasing distance from the SPSPA, statistically proved in the North. Density varied from 3.33 to 182.18 ind.m?3, and differences were also found between the first perimeter (first circular distance band) and the others. The total biomass varied from 15.25 to 524.50 10?3 mg C m?3 and production from 1.19 to 22.04 10?3 mg C m?3d?1. The biomass and production of Undinula vulgaris (Dana, 1849), Acrocalanus longicornis Giesbrecht, 1888 and Calocalanus pavo (Dana, 1849) showed differences between some transects. A trend of declining biodiversity and production with increasing distance from archipelago was observed, suggesting that even small features like the SPSPA can affect the copepod community in tropical oligotrophic oceanic areas.

    Localization properties of particles in one-dimensional incommensurate lattices without interaction are investigated with models beyond the tight-binding Aubry-Andr\\'e (AA) model. Based on a tight-binding t_1 - t_2 model with finite next-nearest-neighbor hopping t_2, we find the localization properties qualitatively different from those of the AA model, signaled by the appearance of mobility edges. We then further go beyond the tight-binding assumption and directly study the...

  6. Macrophytobenthic flora of the Abrolhos Archipelago and the Sebastião Gomes Reef, Brazil

    The Abrolhos Bank, located on the coast of Bahia, Brazil, harbors the largest coral reef system in the South Atlantic. This area has attracted the attention of biologists because of its peculiar mushroom-shaped structures, locally known as "chapeirões", and endemic species of corals and other organisms. The macrophytobenthos compartment plays an important ecological role in the functioning of the bank, and some reports on the presence of seaweeds and seagrasses have been published; however, the data are fragmentary, and a more detailed survey of the macrophytobenthos compartment is lacking. Here we consolidate the information available and add new data obtained from two expeditions focused on seaweed and seagrass diversity from two sectors of the bank: the islands of the Abrolhos archipelago (AA) and the Sebastião Gomes Reef (SG). These sites were selected for their contrasting characteristics. Specifically, SG (15 km off the mouth of the Caravelas River) is subjected to a broader range of anthropogenic impacts and to input of terrigenous sediments, while the AA (54 km offshore) is surrounded by calcareous biogenic sediments, has clearer water and is less affected by human activities. Macrophytobenthic species richness on both reference areas is larger than previously thought. Considering previous records, there are 164 species of macrophytes in AA and 111 species in SG, of which 59 and 74 species are first records for each respective location. The higher species richness at the AA may result from a higher habitat complexity and lower turbidity, but a potential negative effect of enhanced human impacts at SG cannot be ruled out. Considering that macroalgae are relevant components of the benthic community, as producers and structurer organisms, the data presented herein provide a reliable baseline for future environmental studies, and thus may contribute to improve management policies within the unique ecosystem of Abrolhos.

    During the Kerguelen Ocean and Plateau compared Study (KEOPS; January-February 2005) cruise, the area southeast of the Kerguelen Archipelago in the Indian sector of the Southern Ocean was investigated to identify the mechanisms of natural iron fertilization of the Kerguelen Plateau. In this study, the organic speciation of Fe is described. Samples were determined immediately on board using competing ligand-adsorptive cathodic stripping voltammetry (CL-AdCSV). The dissolved organic ligands were always in excess of the dissolved Fe concentration, increasing the residence time in the water column and the potential availability for phytoplankton. The concentration of the dissolved organic ligands ranged from 0.44 to 1.61 nEq of M Fe (=complexation site for Fe), with an average concentration of 0.91 nEq of M Fe (S.D.=0.28, n=113) and a mean logarithm of conditional stability constant (log K') of 21.7 (S.D.=0.28, n=113). A second weaker dissolved organic ligand group was detected in 32% of the samples, with Fe-binding characteristics at the edge of the detection window of the applied method. The occurrence of the highest concentrations of dissolved organic ligands in the wind-mixed surface layer and near the sediment at the bottom of the water column indicated that both phytoplankton and the sediment act as sources. Both sources are in concert with the general conclusions from the KEOPS research on the sources of Fe, where Fe was regenerated, organic Fe-binding ligands were formed in the upper layers, and both Fe and ligands were supplied by the sediment.

  8. Multiscaling statistics of high frequency global solar radiation data in the Guadeloupean Archipelago

    The part of the solar power production from photovoltaiccs systems is constantly increasing in the electric grids. Solar energy converter devices such as photovoltaic cells are very sensitive to instantaneous solar radiation fluctuations. Thus rapid variation of solar radiation due to changes in the local meteorological condition can induce large amplitude fluctuations of the produced electrical power and reduce the overall efficiency of the system. When large amount of photovoltaic electricity is send into a weak or small electricity network such as island network, the electric grid security can be in jeopardy due to these power fluctuations. The integration of this energy into the electrical network remains a major challenge, due to the high variability of solar radiation in time and space. To palliate these difficulties, it is essential to identify the characteristic of these fluctuations in order to anticipate the eventuality of power shortage or power surge. A good knowledge of the intermittency of global solar radiation is crucial for selecting the location of a solar power plant and predicting the generation of electricity. This work presents a multifractal analysis study of 367 daily global solar radiation sequences measured with a sampling rate of 1 Hz over one year at Guadeloupean Archipelago (French West Indies) located at 16o15'N latitude and 60o30'W longitude. The mean power spectrum computed follows a power law behaviour close to the Kolmogorov spectrum. The intermittent and multifractal properties of global solar radiation data are investigated using several methods. Under this basis, a characterization for each day using three multifractal parameters is proposed.

    Late Miocene basanites of Nosy Be and Nosy Sakatia islands (Nosy Be Archipelago, northern Madagascar) carry spinel-facies anhydrous ultramafic xenoliths (lherzolites, harzburgites and wehrlites). Geothermobarometric estimates indicate that these xenoliths derive from shallow mantle depths of 35-40 km, with those from Nosy Be island showing equilibration T (averages in the range of 945-985 °C) lower than the Nosy Sakatia analogues (averages ranging from 1010 to 1110 °C). One Nosy Sakatia mantle xenolith exhibits relatively fertile lherzolite composition, with trace and major element mineral chemistry consistent with a residual character after low degrees (1-2%) of mafic melt extraction. We interpret this composition as that resembling a depleted mantle (DM)-like lithospheric composition before metasomatic overprints. The other lherzolites and harzburgites display petrochemical characters consistent with variable extent of partial melting (up to 18%), associated with pronounced metasomatic overprints caused by migrating melts, as highlighted by enrichments in highly incompatible trace elements (e.g. light rare earth elements, LREE and Sr), together with the abundant occurrence of wehrlitic lithologies. The variability of petrochemical features points to different styles of metasomatism and metasomatic agents. The estimated composition of the parental melts of wehrlites matches that of host basanites. The combination of this evidence with the petrographic features, characterized by coarse-granular to porphyroclastic textures and by the presence of olivine without kink-banding, suggests that wehrlites are veins or pockets of high pressure cumulates within the mantle peridotite. The same melts also metasomatized via porous-flow percolation some lherzolites and harzburgites. Distinctly, a group of lherzolites and harzburgites was metasomatized by a different alkaline melt having markedly lower incompatible trace element contents. Late infiltration of metasomatic fluids is responsible for the spongy texture of some clinopyroxenes of lherzolites, harzburgites and wehrlites.

      Being the first of a series dealing with the entomofauna of the Madeira and Selvagens Islands, this catalogue is a list of all Lepidoptera recorded from this region of Macaronesia, with references to the relevant literature. The checklist includes 37 families, 211 genera and 331 species. 31 species are recorded from Madeira for the first time, and exact data and locality are given for these in the notes. 32 species, which had previously been recorded from Madeira, are removed from the list of Lepidoptera found in the Madeira Islands being misidentifications, doubtful and unconfirmed records, undetermined species requiring further study and accidentally introduced species which have not established themselves in Madeira. No genus of Lepidoptera is endemic to Madeira, but 81 species are endemic to the Madeira Archipelago, and a further 36 species are considered Macaronesian endemics. One species occurs as two distinct subspecies on Madeira Island and Deserta Grande, respectively. We also comment on taxonomicand nomenclatorial problems in a number of species and provide information on host plants in Madeira and other biological details. Index to Latin names of Lepidoptera and host plants are given. The reference list includes 431 references for Madeiran Lepidoptera. The following nomenclatorial changes are proposed: Clepsis retiferana (Stainton, 1859) is removed from synonymy with C. subcostana (Stainton, 1859) (sp. rev.), Cyclophora maderensis ssp. lundbladi (Bryk, 1940) is a synonym of C. maderensis ssp. maderensis (Bethune-Baker, 1891) (n. syn). Agrotis selvagensis Pinker & Bacallado, 1978 is a synonym of A. lanzarotensis Rebel, 1894 (n. syn) and Agrotis trux spp. maderensis Pinker, 1971 is a synonym of A. trux ssp. trux (Hübner, 1824) (n. syn.).

    In the Canadian Arctic Archipelago (CAA), multiyear ice (MYI) replenishment from first-year ice aging (CAAMYI-Oct-1) and Arctic Ocean MYI exchange (CAAMYI-exchange) contribute to the CAA's relatively heavy sea ice conditions at the end of the summer melt season. We estimate these components using RADARSAT and the Canadian Ice Service Digital Archive and explore processes responsible for interannual variability from 1997 to 2013. CAAMYI-Oct-1 (52 ± 36 × 103 km2) provides a larger contribution than CAAMYI-exchange (13 ± 11 × 103 km2). CAAMYI-Oct-1 represents ˜10% of the amount that occurs in the Arctic Ocean. CAAMYI-exchange represents ˜50% of Nares Strait MYI export to Baffin Bay and ˜12% of Fram Strait MYI export to the Greenland Sea. CAAMYI-Oct-1 exhibits dependence on warmer (cooler) summers that increase (decrease) melt evident from strong relationships to surface air temperature (SAT), albedo and total absorbed solar radiation (Qtotal). CAAMYI-exchange is influenced by summer sea level pressure (SLP) anomalies over the Beaufort Sea and Canadian Basin which shifts the primary source of CAAMYI-exchange between less obstructed M'Clure Strait (low SLP anomalies) and the more obstructed Queen Elizabeth Islands (high SLP anomalies). Over the 17-record, appreciable replenishment occurred for most years from 1997 to 2004, reduced replenishment from 2005 to 2012, and large replenishment in 2013. The reduced replenishment period was associated with positive SAT, negative albedo, and positive Qtotal anomalies that facilitated more melt and less CAAMYI-Oct-1, together with high SLP anomalies that facilitated less CAAMYI-exchange. Large replenishment in 2013 was primarily from CAAMYI-Oct-1 attributed to strongly negative SAT and Qtotal anomalies and strongly positive albedo that impeded melt.

    Full Text Available Abstract Background Two concomitant dengue 3 (DEN-3 epidemics occurred in Cape Verde Archipelago and Senegal between September and October 2009. Aedes aegypti was identified as the vector of these epidemics as several DEN-3 virus strains were isolated from this species in both countries. The susceptibility to pyrethroids, organochlorine, organophosphates and carbamate was investigated in two field strains of Aedes aegypti from both countries using WHO diagnostic bioassay kits in order to monitor their the current status of insecticide susceptibility. Findings The two tested strains were highly resistant to DDT. The Cape Verde strain was found to be susceptible to all others tested insecticides except for propoxur 0.1%, which needs further investigation. The Dakar strain was susceptible to fenitrothion 1% and permethrin 0.75%, but displayed reduced susceptibility to deltamethrin, lambda-cyhalothrin and propoxur. Conclusions As base-line results, our observations stress a careful management of insecticide use for the control of Ae. aegypti. Indeed, they indicate that DDT is no longer efficient for the control of Ae. aegypti populations in Cape Verde and Dakar and further suggest a thorough follow-up of propoxur susceptibility status in both sites and that of deltamethrin and lambda-cyhalothrin in Ae. aegypti populations in Dakar. Thus, regular monitoring of susceptibility is greatly needed as well as the knowing if this observed resistance/susceptibility is focal or not and for observed resistance, the use of biochemical methods is needed with detailed comparison of resistance levels over a large geographic area.

  14. Low-frequency western Pacific Ocean sea level and circulation changes due to the connectivity of the Philippine Archipelago

    2013-12-01

    Interannual-to-decadal sea level and circulation changes associated with the oceanic connectivity around the Philippine Archipelago are studied using satellite altimeter sea surface height (SSH) data and a reduced gravity ocean model. SSHs in the tropical North Pacific, the Sulu Sea and the eastern South China Sea (ESCS) display very similar low-frequency oscillations that are highly correlated with El Niño and Southern Oscillation. Model experiments reveal that these variations are mainly forced by the low-frequency winds over the North Pacific tropical gyre and affected little by the winds over the marginal seas and the North Pacific subtropical gyre. The wind-driven baroclinic Rossby waves impinge on the eastern Philippine coast and excite coastal Kelvin waves, conveying the SSH signals through the Sibutu Passage-Mindoro Strait pathway into the Sulu Sea and the ESCS. Closures of the Luzon Strait, Karimata Strait, and ITF passages have little impacts on the low-frequency sea level changes in the Sulu Sea and the ESCS. The oceanic pathway west of the Philippine Archipelago modulates the western boundary current system in the tropical North Pacific. Opening of this pathway weakens the time-varying amplitudes of the North Equatorial Current bifurcation latitude and Kuroshio transport. Changes of the amplitudes can be explained by the conceptual framework of island rule that allows for baroclinic adjustment. Although it fails to capture the interannual changes in the strongly nonlinear Mindanao Current, the time-dependent island rule is nevertheless helpful in clarifying the role of the archipelago in regulating its multidecadal variations.

    Full Text Available Property rights are important institutions for regulating the use of valuable natural resources from coastal ecosystems. In this case study, we identify and analyze property rights and user patterns related to small-scale coastal fisheries in the Stockholm Archipelago, Sweden. User patterns and user groups have changed significantly over the last century, as commercial fishing has been increasingly replaced by recreational activities. Interviews with local resource users and owners of water properties in two different areas, Möja and Ornö parishes within the Stockholm Archipelago, revealed a very diverse pattern of property and user rights, with a large number of water and fishing rights owners. Recreational fisheries, including both sport and household fishing, seem to predominate in both areas, but ownership differs. In Möja, most waters are collectively owned, whereas in Ornö, individual ownership predominates. Very few examples of local influence on fisheries management were found in either area, although the social structure for joint management does exist in Möja. Instead, larger-scale institutions at the regional, national, or international level regulate fisheries, often not addressing local conditions and fish populations. The ongoing shift in resource use has created a heterogeneous user group, and the limitations of centralized management authorities in dealing with the diversity in the coastal ecosystem have created mismatches within the social–ecological system. Combined with a large-scale decline in coastal fish stocks, these mismatches challenge the existing local property rights arrangements as well as the more centralized regulatory management structure. A key issue for fisheries management is how to develop and stimulate appropriate distribution of management functions at different geographical scales and organizational levels. The complexity and diversity in archipelago fisheries call for multilevel arrangements and cross-scale coordination, and initiatives have been taken by both central governmental authorities and local user groups to collaborate concerning habitat restoration and protection of important spawning grounds.

  17. Structure of microemulsions by SANS

    International Nuclear Information System (INIS)

    Small-angle neutron scattering (SANS) has been used to determine the structure of microemulsions in the system hydrocarbon-water-sodium di-ethylhexylsulfosuccinate (AOT). SANS spectra taken in a deuterated solvent showed a perfect Guinier fit with a radius of gyration of 15A regardless of the amount of AOT from 0.1 to 5% present. By varying the proportions of deuterated and undeuterated solvent to vary the contrast between the micelles and the solvent, it is concluded that the micelles are basically monodispersed spherical aggregations of 22 AOT molecules

  20. Long-term changes of species richness in a breeding bird community of a small Mediterranean archipelago

    Martínez-Abraín, A.

    2005-12-01

    Full Text Available We analyzed the pattern of species richness changes in a bird–breeding bird community on a small western Mediterranean archipelago (Columbretes Islands over a 40–year period (1964–2003. The aim of this study was to qualitatively account for the relative roles of local and regional factors in shaping the community. As expected, we found that regional factors (at the metapopulation spatial scale increased diversity whereas local factors (i.e. ecological probably prevented further increases in diversity. We found that the archipelago gained four new species (two seabirds and two falconids during the study period, whereas no extinctions were recorded. The community seems partially or completely closed to some groups of species (e.g. small–sized birds such as passerines and storm–petrels, probably owing to predatory exclusion by Eleonora falcons (Falco eleonorae. As newly arrived species have breeding calendars that do not fully overlap with those of resident species, competition for space in a rather saturated area is prevented. Preservation of rare species which increase gamma (regional diversity rather than alpha diversity with common species should be the main local conservation goal.

    We report palaeointensity estimates obtained from three Oligocene volcanic sections from the Kerguelen Archipelago (Mont des Ruches, Mont des Tempetes, and Mont Rabouillere). Of 402 available samples, 102 were suitable for a palaeofield strength determination after a preliminary selection, among which 49 provide a reliable estimate. Application of strict a posteriori criteria make us confident about the quality of the 12 new mean-flow determinations, which are the first reliable data available for the Kerguelen Archipelago. The Virtual Dipole Moments (VDM) calculated for these flows vary from 2.78 to 9.47 10e22 Am2 with an arithmetic mean value of 6.15+-2.1 10e22 Am2. Compilation of these results with a selection of the 2002 updated IAGA palaeointensity database lead to a higher (5.4+-2.3 10e22 Am2) Oligocene mean VDM than previously reported, identical to the 5.5+-2.4 10e22 Am2 mean VDM obtained for the 0.3-5 Ma time window. However, these Kerguelen palaeointensity estimates represent half of the reliable Ol...

  2. New data on Upper Carboniferous–Lower Permian deposits of Bol'shevik Island, Severnaya Zemlya Archipelago

    Victoria B. Ershova

    2015-05-01

    Full Text Available We present here a detailed study of the Upper Carboniferous–Lower Permian stratigraphy of Bol'shevik Island in the Severnaya Zemlya Archipelago, consisting of the analysis of sedimentary structures and lithostratigraphy, U/Pb detrital zircon dating and structural studies. The preserved sedimentary structures suggest that the studied strata were deposited in a relatively small meandering fluvial system. U/Pb dating of detrital zircons reveals that the Upper Carboniferous–Lower Permian sandstones contain a primary age population ranging from 450 to 570 millions of years, with a predominance of Early–Middle Ordovician zircons. This detrital zircon distribution indicates that the studied formations were derived locally from the erosion of Lower Ordovician deposits of Bol'shevik Island or elsewhere in the archipelago. Our structural studies suggest that Upper Carboniferous–Lower Permian deposits are deformed into a series of west–north-west verging open asymmetric folds, suggesting a west–north-west direction of tectonic transport and that deformation across the island is post-Early Permian in age.

  3. Microsatellite variation suggests a recent fine-scale population structure of Drosophila sechellia, a species endemic of the Seychelles archipelago.

    Drosophila sechellia is closely related to the cosmopolitan and widespread model species, D. simulans. This species, endemic to the Seychelles archipelago, is specialized on the fruits of Morinda citrifolia, and harbours the lowest overall genetic diversity compared to other species of Drosophila. This low diversity is associated with a small population size. In addition, no obvious population structure has been evidenced so far across islands of the Seychelles archipelago. Here, a microsatellite panel of 17 loci in ten populations from nine islands of the Seychelles was used to assess the effect of the D. sechellia's fragmented distribution on the fine-scale population genetic structure, the migration pattern, as well as on the demography of the species. Contrary to previous results, also based on microsatellites, no evidence for population contraction in D. sechellia was found. The results confirm previous studies based on gene sequence polymorphism that showed a long-term stable population size for this species. Interestingly, a pattern of Isolation By Distance which had not been described yet in D. sechellia was found, with evidence of first-generation migrants between some neighbouring islands. Bayesian structuring algorithm results were consistent with a split of D. sechellia into two main groups of populations: Silhouette/Mahé versus all the other islands. Thus, microsatellites suggest that variability in D. sechellia is most likely explained by local genetic exchanges between neighbouring islands that have recently resulted in slight differentiation of the two largest island populations from all the others.

  4. A spatio-temporal model for the invasion of New Zealand archipelago by the Pacific rat Rattus exulans

    International Nuclear Information System (INIS)

    New Zealand is at the southern limits of the human-extended geographic range of the Pacific rat Rattus exulans. On the two main islands, radiocarbon dates on rat bones from natural sites show that rat populations were established more than 1000 years before permanent human settlement, presumably during transient visits by Polynesian voyagers. Both main islands were colonised after these first contacts, but offshore and outlying islands were not reached by rats until after Polynesian settlement about 700 years BP. Chatham Island was not colonised by Pacific rats until about 650 years BP. I present a model that relates the time of first appearance of rats in the fossil record and the exploitation of native fauna to the pattern of spread of the rat through the archipelago. I hypothesise that the stepwise spread of the rat through the archipelago is mirrored by the pattern of reduction and extinction of indigenous fauna vulnerable to rat predation. The 1000 year delay between the arrival of rats and permanent human settlement suggests that the New Zealand biota was already stressed by an introduced predator before humans added habitat destruction and over-hunting.

    The preferential formation of Ca-rich dolomite precursors in modern peritidal environments has been associated with the degradation of buried microbial mats, with complexation of Ca and Mg cations by extracellular polysaccharides, and alkalinity generation, mostly through bacterial sulfate reduction. However, it remains unclear why Ca-dolomite would not occur in suboxic sediments where bacterial Mn(IV) and/or Fe(III) reduction are important sources of alkalinity, and the role, if any, of Fe- and Mn-recycling in its diagenetic stabilization to more stoichiometric dolomite is unknown. In a shoaling-upward parasequence in the Archipelago Los Roques, Venezuela, an abundance of Ca-dolomite coincides with a relative decrease in bulk-sediment iron concentrations. These sediments were analyzed with multiple analytical tools, including EPMA, ICP-MS, synchrotron-based XRF, XRD, and spatially resolved XANES. Results demonstrate that the distribution of spheroidal aggregates of nanometer-scale Ca-rich dolomite rhombohedra is linked with interstitial elemental sulfur and manganese accumulations, with Mn occurring in several oxidation states (Fig. 1). Based on our observations at this novel dolomite-forming site, we suggest that in peritidal settings the burial of metal-reactive microbial mats act as a barrier capable of concentrating dissolved reactive species that promote greater sediment residence times in suboxic (manganic) zones, where the recycling of Mn not only plays an important role in the remineralization of organic matter, but also sustains elevated alkalinity and dissolved pore water sulfide concentrations. The last two effects have been previously suggested to promote Mg dehydration, the major kinetic barrier to dolomite nucleation. Figure 1. Normalized Mn K-edge merged spectra of a 5 x 5 ?m analytical area bearing dolomite cements. A: The K-edge exhibits two main features at about 6554 and 6558 eV. B: Intermediate Mn (III) is identified by the positive slope of the first derivative of the XANES spectra in the interval 6547.9-6549.0 eV. C: A least-squares fitting of the spectra was performed to quantify the Mn species present. The spectra can be fitted with four model compounds, Mn2O3 (52.5 × 5.2%), MnCO3 (22.2 × 1.3%), gamma-MnOOH (15.0 × 5.0%), and Mn3O4 (10.3 × 7.7%), suggesting that these phases coexist in the dolomite-bearing microcrystalline cements.

    Among highly inclined asteroids, the region of the central main belt between the 3J:-1A and 5J:-2A mean-motion resonances has long been known to host the Pallas and Hansa dynamical families. This region is characterized by the presence of the ?6,?5 and ?16 secular resonances, which in conjunction with the 8J:-3A mean-motion resonance divide the area into eight regions, the stable islands of the archipelago. Using a set of proper elements available at the Asteroids Dynamic Site (AstDyS) at the time, Gil-Hutton identified a family around (686) Gersuind and two more minor clumps around (945) Barcelona and (148) Gallia in the space of synthetic proper elements. In this work I compute a new set of synthetic proper elements for 2310 numbered and 2142 multi-opposition objects in this region. The use of the frequency-modified Fourier transform method allowed me to obtain non-negative estimates of the proper frequency of argument of pericentre precession g for members of the Hansa families characterized by values of eforced larger than efree, and to solve the problem of the non-linear dependence of g versus n observed by Carruba & Michtchenko. My analysis shows that the two minor clumps of Gil-Hutton should now be considered dynamical families. Also, a new family in the domains of both proper elements (a, e, sini) and frequencies (n, g, g + s) around (1222) Tina is discovered in this work, as well as a new frequency family around (4203) Brucato. Nine minor clumps, one of which is visible in both domains, are also observed. The taxonomical analysis of family members suggests that the Pallas family is compatible with a B-type composition (but two members are classified as C interlopers), while the Hansa family is possibly an S-type one. Sloan Digital Sky Survey Moving Object Catalog (SDSS-MOC3) data suggest that the Barcelona family might be an Sq group, and the Gersuind, Gallia and Tina ones should belong to the S complex. Geometric albedo data seem to confirm the possibility that the Barcelona and Gersuind families belong to the S complex. Data on cumulative size distributions, collisions time-scales, rotation rates and dynamics in this region are also revised in this work.

    The Hornsund fjord is located in the southwestern part of Spitsbergen- the biggest island of the Svalbard Archipelago. The fjord is influenced by two major currents in this area. The first one is the current carrying the cold and less saline waters around the southern Spitsbergen tip, often called the Sørkapp Current or the South Cape Current. The second is the well-known West Spitsbergen Current (WSC), carrying salty and warm Atlantic Waters through Fram Strait into the Arctic Ocean. From a biological point of view, Hornsund can be treated as a young unstable system or cold system, which suggests that it is under an influence of the South Cape Current. Because of limited measurements in this area, the hydrodynamic model MIKE3D has been implemented for this fjord to diagnose which current has the main influence on Hornsund. The fjord domain was extended into the shelf area. At the lateral boundary of the extended domain, data from the ROMS simulation of the Svalbard area made by the Norwegian Institute of Marine Research (IMR) with resolution of 800 m have been used. Atmospheric data from European Centre for Medium Weather Forecast (ECMWF) were employed as well as from the Global Data Assimilation System (GDAS, 1 and 0.5 degrees) reanalysis that uses metrological data from Polish Polar Station located in Hornsund. Based on 5 years of simulation (2005-2010) seasonal and annual general circulation in the fjord has been described. Estimation of the heat transport between fjord and ocean, and between fjord and atmosphere will permit to establish the heat budget and help to evaluate the influence of the South Cape Current and WSC on the fjord ecosystem development. An influence of the fresh water fluxes and vertical structure of water masses and their transformations will be also discussed. This work was partially performed in the frame of the projects GAME (DEC-2012/04/A/NZ8/00661) and AWAKE2 (Pol-Nor/198675/17/2013)

    Indonesian archipelago region is located in active tectonic setting and high seismicity zone. During the last decade, Indonesian was experienced with destructive major earthquakes causing damage and victims. The information of precise earthquake location parameters are very important in partular for earthquake early warning to the society and for advance seismic studies. In this study, we attempted to improve hypocenter location compiled by BMKG for time periods of April, 2009 up to June, 2014 for about 22,000 earthquake events around Indonesian region. For the firts time, we applied teleseismic double-difference relocation algorithm (teletomoDD) to improve hypocenter region in Indonesia region combining regional and teleseismic stations. Hypocenter relocation was performed utilizing local, regional, and teleseismic P-wave arrival time data. Our relocation result show that travel-time RMS errors were greatly reduced compared to the BMKG catalog. Seismicity at shallower depth (less than 50 km) shows significantly improvement especially in depth, and refined shallow geological structures, e.g. trench and major strike slip faults. Clustered seismicity is also detected beneath volcanic region, and probably related volcano activities and also major faults nearby. In the Sunda arc region, seismicity at shallower depth centered at two major distributions parallel to the trench strike direction, i.e. around fore-arc and in mainland that related to major fault, e.g. the Sumatran fault, and volcanic fronts. Below Central Java region, relocated hypocenter result showed double seismic zone pattern. A seismic gap is detected around the Sunda-Banda transition zone where transition between oceanic subduction to continental crust collision of Australian plate occurs. In Eastern Indonesia region, shallow earthquakes are observed related to major strike slip faults, e.g. Sorong and Palu-Koro fault, volcanism, and shallow part of subduction and collision zones. We also compare our result in the Sunda Arc region with slab1.0 model and our relocated seismicity shows good agreement with the previous slab geometry. Horizontal position shift of relocated events are mostly perpendicular to the trench directions.

    In this paper, we report a highly efficient, scalable approach to the total synthesis of conformationally unrestricted, electronically isolated arrays of alkyl-tethered polycyclic aromatic chromophores. This new class of modular molecules consists of polycyclic aromatic "islands" comprising significant structural fragments present in unrefined heavy petroleum, tethered together by short saturated alkyl chains, as represented in the "archipelago model" of asphaltene structure. The most highly branched archipelago compounds reported here share an architecture with first-generation dendrimeric constructs, making the convergent, chromatography-free synthesis described herein particularly attractive for further extensions in scope and applications to materials chemistry. The syntheses are efficient, selective, and readily adaptable to a multigram scale, requiring only inexpensive, "earth-abundant" transition-metal catalysts for cross-coupling reactions and extraction and fractional crystallization for purification. This approach avoids typical limitations in cost, scale, and operational practicality. All of the archipelago compounds and synthetic intermediates have been fully characterized spectroscopically and analytically. The solid-state structure of one archipelago model compound has been determined by X-ray crystallography. PMID:25569143

    Let K(n) be the nth Morava K--theory at a prime p. This paper is a thorough study of questions like the following: to what extent does the K(n)--localization, or the K(n)--homology, of a spectrum X determine the K(n)--homology of its 0th space X_0? Our methods combine techniques from modern homotopical algebra with chromatic homotopy. In particular, we use the telescopic functors of Bousfield and the author (dependent on the Nilpotence Theorem of Devanitz, Hopkins, and Smith), as wel as Topological Andre--Quillen Homology and Goodwillie calculus in nonconnective settings.

  16. Are There Spatial or Temporal Patterns to Holocene Explosive Eruptions in the Aleutian Archipelago? A Work in Progress

    By examining the existing geological and archeological record of radiocarbon dated Aleutian tephras of the last 12,000 years, this study sought to determine whether there were spatial or temporal patterns of explosive eruptive activity. The Holocene tephra record has important implications because two episodes of migration and colonization by humans of distinct cultures established the Unangan/Aleut peoples of the Aleutian Islands concurrently with the volcanic activity. From Aniakchak Volcano on the Alaska Peninsula to the Andreanof Islands (158 to 178° W longitude), 55 distinct tephras represent significant explosive eruptions of the last 12,000 years. Initial results suggest that the Andreanof and Fox Island regions of the archipelago have had frequent explosive eruptions whereas the Islands of Four Mountains, Rat, and Near Island regions have apparently had little or no eruptive activity. However, one clear result of the investigation is that sampling bias strongly influences the apparent spatial patterns. For example field reconnaissance in the Islands of Four Mountains documents two Holocene calderas and a minimum of 20 undated tephras in addition to the large ignimbrites. Only the lack of significant explosive activity in the Near Islands seems a valid spatial result as archeological excavations and geologic reports failed to document Holocene tephras there. An intriguing preliminary temporal pattern is the apparent absence of large explosive eruptions across the archipelago from ca. 4,800 to 6,000 yBP. To test the validity of apparent patterns, a statistical treatment of the compiled data grappled with the sampling bias by considering three confounding variables: larger island size allows more opportunity for geologic preservation of tephras; larger magnitude eruption promotes tephra preservation by creating thicker and more widespread deposits; the comprehensiveness of the tephra sampling of each volcano and island varies widely because of logistical and financial limitations. This initial statistical investigation proposes variables to mitigate the effects of sampling bias and makes recommendations for sampling strategies to enable statistically valid examination of research questions. Further, though caldera-forming eruptions occurred throughout the Holocene - and several remain undated - four of six dated eruptions occurred throughout the archipelago between 8,000-9,100 yBP, a period coinciding with some of the earliest human occupation (Early Anangula Phase) of the eastern Aleutians.

  1. Seismicity of Barentsburg area at the Spitsbergen Archipelago: overlapping the tectonic and technogenic sources ?

    2003-04-01

    The Western Spitsbergen Island (WSI) is located at a passive margin of the Barents shelf platform, close to the North Atlantic spreading zone marked by the Knipovich Ridge at the ocean bottom. Sublateral transform faults intersect a continental slope and provide a segmentation of uplifted over sea level block of continental crust. As a result, the Spitsbergen Archipelago is divided on small "lands" and islands by deep fiords and straights (for example, the Isfiord and Van Mijen fiord in WSI). A scope of seismic data for the last 40 years shows that earthquakes locates along the Knipovich Ridge in the ocean, and along interplate transform faults in the platform margin. In the WSI the earthquakes are concentrated in two narrow belts: Van Mijen Fiord - Heer Land and Horsund Fiord - Hamber Baystributed. A frequency of seismic events here vary of 5 to 15 ones per day, in contrast to "a quiet areas" out of the belts where the frequency use to be less in many times. The most strong earthquake with magnitude 6.0 was recorded in the Heer Land at 18 January, 1976. The Russian settlement and coal mines Barentsburg is situated within the "quiet area" of 40 km to the North from the Van Mijen seismic belt. In this area the earthquakes with local magnitude ML > 2.0 never been recorded, but underground mining operations at depth of 300-600 meters below surface associate with rock bursts. Due to evaluate a seismic hazard and clarify relationships between natural and human induced seismicity, the digital 3-component seismic station GBV 316B was installed in Barentsburg by the Kola Regional Seismological Centre (KRSC), and recording of weak seismic emission was performed in co-operation with NORSAR during a period since 01/12/2000 till 19/04/2001. Within the term a mining activity was stable till 25/03/2001, and in period from 26 March till 19 April the mines were idle. Totally of 541 seismic events were detected in the reference area 5x6 km, and only the largest one with ML of 3.0 were also detected 28012001 by the remote IMS stations, including ARCES in Norway at distance of 1000 km from WSI. There was found two main "local source sites" coinciding in space with the Southern and Northern mine fields of the "Arctikugol'" coal mines. The size of sites are 1x1 km and 0.5x1.5 km correspondingly, and they accumulated 523 weak seismic events, induced by rock bursts in the mines or by stress release in wall rocks. Time series in both sites are similar (the correlation ratio was evaluated for 10-days sets as 0.72). Only 12 very weak events in the sites and no one outside were detected when the mines were idle. During the period of active mining operations totally 18 events were detected outside of the "source sites". The obtain data allow to suggest, that mining activity is the main factor triggering both the seismic emission within mining fields and the local earthquakes in surrounding area, but more detail and continuous observations are needed to clarify an effect of technogenic seismicity on a geodynamic regime in nearby interplate faults.

    Full Text Available El presente trabajo retoma la problemática de los límites y las limitaciones del "Archipiélago Vertical" planteada hace tres décadas por John V. Murra y a la que todavía no se le ha podido dar una respuesta satisfactoria. Con esto no pretendemos resolver el desafío legado por Murra, sino dar una diferente lectura a la información arqueológica existente y con ello formular una hipótesis que pueda orientar el debate y la búsqueda de respuestas bajo un panorama de mayor amplitud. Nuestro enfoque se centra en el segmento de la vertiente occidental andina correspondiente al norte del actual territorio chileno, planteando que en esta franja el modelo de verticalidad archipielágica, tal como definido por Murra, se consolidó solamente en el Período Intermedio Tardío. Con anterioridad (período Medio, la necesidad de complementariedad vertical habría sido resuelta a través del macrosistema orquestado por Tiwanaku, entidad que perfeccionó el "sistema de interacción reticular" (Llagostera 2006, de data anterior, por lo que no necesariamente tuvo que recurrir a colonias. En el Intermedio Tardío se conjugaron acontecimientos sociopolíticos y eventos medioambientales que motivaron una reestructuración sin precedentes en las tierras altoandinas y en los Valles Occidentales. En estos últimos, las poblaciones vallunas que habían alcanzado su apogeo sociocultural se habrían reestructurado bajo mecanismos que podrían asimilarse a los sistemas de "dualidad". En tanto, las poblaciones del altiplano, que estaban siendo flageladas por una intensa sequía, habrían iniciado un clima de agresión y de violencia hacia las poblaciones de las cabeceras de los valles occidentales para apoderarse de la producción hortícola y de sus tierras. Finalmente, los reductos de estas poblaciones precordilleranas (que originalmente hacían parte de la dualidad valluna habrían caído en poder de las poblaciones altiplánicas, convirtiéndose en colonias ("islas" de estas últimas, consolidando la estructura de "archipiélago vertical", con cabecera en el altiplano. De esta manera se habría dado forma a los archipiélagos étnicos Caranga, Quillaca y Lipes, que serían los más meridionales del mundo andino.The present work returns to the problem of the limits and limitations of the 'vertical archipelago', raised three decades ago by John V. Murra, and which still remains without a satisfactory solution. Rather than resolve the challenge left by Murra, / here offer a different approach to the archaeological information, which leads me to formulate a hypothesis that may guide the debate and search for answers within a wider context. Concentrating on the Western slopes of the Andes in the North of Chile, I propose that the model of the vertical archipelago, as defined by Murra, was consolidated only in the Late Intermediate Period. During the Middle Horizon, the need for vertical complementarity could have been resolved through the macro-system organized by Tiwanaku, a civilization that perfected the older "system of reticulated interaction " (Llagostera 2006, and did not depend on colonies for access to distant resources. But in the Late Intermediate Period, sociopolitical and environmental events combined to bring about a new form of organization in the Andean highlands and in the Western Valleys of the Pacific. In the latter, populations that had reached their sociocultural upper limit would have been restructured under mechanisms assimilable to those of 'duality'. Meanwhile the highland populations, afflicted by an intense drought, would have unleashed violent attacks against those living in the head-waters of the Western Valleys to get hold of their agricultural lands. Finally, the remnants of these pre-Andean populations (originally part of the valley dual organization would have fallen into the hands of the altiplanic populations, becoming colonies ('islands' which consolidated a 'vertical archipelago structure' whose nuclei lay on the Altiplano. In this way were formed the southernmost archipelagoes of the An

The diploid number is 46, with nine [...] pairs of macrochromosomes (three metacentrics, four subtelocentrics and two acrocentrics) and 14 pairs of microchromosomes. The Ag-NOR is located in the telomeric region of the long arm of metacentric chromosome 2 and FISH revealed signals only in the telomeric region of all chromosomes. Further cytogenetic data on other amphisbaenians as well as a robust phylogenetic hypothesis of this clade is needed in order to understand the evolutionary changes on amphisbaenian karyotypes.

    Full Text Available The relationship between bacterioplankton and environmental forcing in the Berlengas Archipelago (Western Coast of Portugal were studied between February 2006 and February 2007 in two sampling stations: Berlenga and Canal, using an HJ-biplot. The HJ-biplot showed a simultaneous display of the three main metabolic groups of bacteria involved in carbon cycling (aerobic heterotrophic bacteria, sulphate-reducing bacteria and nitrate-reducing bacteria and environmental parameters, in low dimensions. Our results indicated thatbacterial dynamics are mainly affected by temporal gradients (seasonal gradients with a clear winter versus summer opposition, and less by the spatial structure (Berlenga and Canal. The yearly variation in the abundance of aerobic heterotrophic bacteria were positively correlated with those in chlorophyll a concentration, whereas ammonium concentration and temperature decreased with increasing phosphates and nitrites concentration. The relationship between aerobic heterotrophic bacteria, chlorophyll a and ammonium reveals that phytoplankton is an important source of organic substrates for bacteria.

    The economic development and population growth in recent Asia have been increasing air pollution. A computer simulation study showed that air pollutants emitted from Asian continent could spread quickly within northern hemisphere. We initiated a study to elucidate the special distribution and chemical characterization of atmospheric aerosols around Okinawa archipelago, Japan. Okinawa Island is situated approximately 1500 km south of Tokyo, Japan, 2000 km southeast of Beijing, China, and 1000 km south of South Korea. Its location in Asia is well suited for studying long-range transport of air pollutants in East Asia because maritime air mass prevails during summer, while continental air mass dominates during fall, winter, and spring. The maritime air mass data can be seen as background and can be compared with continental air masses which have been affected by anthropogenic activities. We simultaneously collected bulk aerosol samples by using the same types of high volume air samplers at Cape Hedo Atmosphere and Aerosol Monitoring Station (CHAAMS, Okinawa Island), Kume Island (ca. 160 km south-west of CHAAMS) and Minami-daitou Island (ca. 320 km south-east of CHAAMS). We determined the concentrations of water-soluble anions, cations and dissolved organic carbon (DOC) using ion chromatography, atomic absorption spectrometry, and total organic carbon analyzer, respectively. We report and discuss spatial distribution and temporal variation of chemical species concentrations in bulk atmospheric aerosols collected during July, 2008 to July, 2009. We determine “background” concentration of chemical components in Okinawa archipelago. We then compare each chemical component among CHAAMS, Kume Island and Minami-daito Island to elucidate the influence of the long-range transport of chemical species from Asian continent.

    Threespine stickleback populations are model systems for studying adaptive evolution and the underlying genetics. In lakes on the Haida Gwaii archipelago (off western Canada), stickleback have undergone a remarkable local radiation and show phenotypic diversity matching that seen throughout the species distribution. To provide a historical context for this radiation, we surveyed genetic variation at >1000 single nucleotide polymorphism (SNP) loci in stickleback from over 100 populations. SNPs included markers evenly distributed throughout genome and candidate SNPs tagging adaptive genomic regions. Based on evenly distributed SNPs, the phylogeographic pattern differs substantially from the disjunct pattern previously observed between two highly divergent mtDNA lineages. The SNP tree instead shows extensive within watershed population clustering and different watersheds separated by short branches deep in the tree. These data are consistent with separate colonizations of most watersheds, despite underlying genetic connections between some independent drainages. This supports previous suppositions that morphological diversity observed between watersheds has been shaped independently, with populations exhibiting complete loss of lateral plates and giant size each occurring in several distinct clades. Throughout the archipelago, we see repeated selection of SNPs tagging candidate freshwater adaptive variants at several genomic regions differentiated between marine-freshwater populations on a global scale (e.g. EDA, Na/K ATPase). In estuarine sites, both marine and freshwater allelic variants were commonly detected. We also found typically marine alleles present in a few freshwater lakes, especially those with completely plated morphology. These results provide a general model for postglacial colonization of freshwater habitat by sticklebacks and illustrate the tremendous potential of genome-wide SNP data sets hold for resolving patterns and processes underlying recent adaptive divergences.

    The susceptibility of reef-building corals to climatic anomalies is well documented and a cause of great concern for the future of coral reefs. Reef corals are normally considered to tolerate only a narrow range of climatic conditions with only a small number of species considered heat-tolerant. Occasionally however, corals can be seen thriving in unusually harsh reef settings and these are cause for some optimism about the future of coral reefs. Here we document for the first time a diverse assemblage of 225 species of hard corals occurring in the intertidal zone of the Bonaparte Archipelago, north western Australia. We compare the environmental conditions at our study site (tidal regime, SST and level of turbidity) with those experienced at four other more typical tropical reef locations with similar levels of diversity. Physical extremes in the Bonaparte Archipelago include tidal oscillations of up to 8 m, long subaerial exposure times (>3.5 hrs), prolonged exposure to high SST and fluctuating turbidity levels. We conclude the timing of low tide in the coolest parts of the day ameliorates the severity of subaerial exposure, and the combination of strong currents and a naturally high sediment regime helps to offset light and heat stress. The low level of anthropogenic impact and proximity to the Indo-west Pacific centre of diversity are likely to further promote resistance and resilience in this community. This assemblage provides an indication of what corals may have existed in other nearshore locations in the past prior to widespread coastal development, eutrophication, coral predator and disease outbreaks and coral bleaching events. Our results call for a re-evaluation of what conditions are optimal for coral survival, and the Bonaparte intertidal community presents an ideal model system for exploring how species resilience is conferred in the absence of confounding factors such as pollution.

  12. Sea-ice crossings by caribou in the south-central Canadian Arctic Archipelago and their ecological importance

    Full Text Available The islands of the Canadian Arctic Archipelago lie immediately north of mainland North America in the Arctic Ocean. They are surrounded by ice for most of each year. Caribou (Rangifer tarandus cross the sea ice in seasonal migrations among the islands and between the mainland and Arctic Islands. We compiled observations of 1272 discrete caribou crossings on the sea ice of northeastern Franklin Strait, Bellot Strait, Peel Sound and Baring Channel in the south-central Canadian Arctic Archipelago during four May—June search periods from 1977 to 1980. We clustered the 850 caribou trails found on the sea ice of northeastern Franklin Strait and on outer Peel Sound as 73 sea-ice crossing sites. We investigated whether caribou at the origin of a sea-ice crossing site could see land on the opposite side at the potential terminus. We measured the straight-line distance from where the caribou first came onto the ice (origin to the first possible landfall (potential terminus. Potential termini were geodetically visible to caribou from elevated terrain near 96% of the origins of the 73 sea-ice crossing sites and still visible at sea-level at the origins on 68%. Caribou are able to take advantage of seasonal use of all of the islands and the peninsula by making sea-ice crossings, thereby helping to increase the magnitudes and durations of population highs and reduce their lows. Knowledge of these alternative pat¬terns of use made possible by sea-ice crossings is necessary to fully understand the population dynamics of these caribou and the importance of possible future changes in ice cover.

  13. A five million year record of compositional variations in mantle sources to magmatism on Santiago, southern Cape Verde archipelago

    DEFF Research Database (Denmark)

    Barker, Abigail K.; Holm, Paul Martin

    2010-01-01

    High-precision Pb isotope data and Sr-Nd-Hf isotope data are presented together with major and trace element data for samples spanning the 4.6 Ma history of volcanism at Santiago, in the southern Cape Verde islands. Pb isotope data confirm the positive ¿8/4 signature of the southern islands indicating that the north-south compositional heterogeneity in the Cape Verde archipelago has persisted for at least 4.6 Ma. The Santiago volcanics show distinct compositional differences between the old, intermediate and young volcanics, and suggest greater involvement of an enriched mantle (EM1)-like source over time. Isotopic variations in the Santiago volcanics indicate convergence towards a homogeneous EM1-like end-member and distinct temporal variations in the FOZO-like end-member. Santiago and Santo Antão (a northern island, Holm et al. 2006), show a simultaneous decrease in 208Pb/204Pb of the high 206Pb/204Pb FOZO-like source with time. Such systematic archipelago-wide variations in the FOZO-like component suggest that this component is more likely to be present as a coherent package of recycled ocean crust rather than as multiple small heterogeneities dispersed in the upwelling mantle. The temporal variations in 208Pb/204Pb reflect minor lateral variations in Th/U of this recycled ocean crust package entering the melting zone beneath the islands. The location of the EM1-like component is more equivocal. A shallow lithospheric location is possible, but this would require a coincidence between spatial compositional variations in the lithosphere (EM1 is spatially restricted to the southern islands) and flow lines in the upwelling mantle revealed by seismic anisotropy. Therefore, we favour a deeper asthenospheric mantle source for the EM1-like source

    2010-06-01

    Full Text Available El presente trabajo retoma la problemática de los límites y las limitaciones del "Archipiélago Vertical" planteada hace tres décadas por John V. Murra y a la que todavía no se le ha podido dar una respuesta satisfactoria. Con esto no pretendemos resolver el desafío legado por Murra, sino dar una dif [...] erente lectura a la información arqueológica existente y con ello formular una hipótesis que pueda orientar el debate y la búsqueda de respuestas bajo un panorama de mayor amplitud. Nuestro enfoque se centra en el segmento de la vertiente occidental andina correspondiente al norte del actual territorio chileno, planteando que en esta franja el modelo de verticalidad archipielágica, tal como definido por Murra, se consolidó solamente en el Período Intermedio Tardío. Con anterioridad (período Medio), la necesidad de complementariedad vertical habría sido resuelta a través del macrosistema orquestado por Tiwanaku, entidad que perfeccionó el "sistema de interacción reticular" (Llagostera 2006), de data anterior, por lo que no necesariamente tuvo que recurrir a colonias. En el Intermedio Tardío se conjugaron acontecimientos sociopolíticos y eventos medioambientales que motivaron una reestructuración sin precedentes en las tierras altoandinas y en los Valles Occidentales. En estos últimos, las poblaciones vallunas que habían alcanzado su apogeo sociocultural se habrían reestructurado bajo mecanismos que podrían asimilarse a los sistemas de "dualidad". En tanto, las poblaciones del altiplano, que estaban siendo flageladas por una intensa sequía, habrían iniciado un clima de agresión y de violencia hacia las poblaciones de las cabeceras de los valles occidentales para apoderarse de la producción hortícola y de sus tierras. Finalmente, los reductos de estas poblaciones precordilleranas (que originalmente hacían parte de la dualidad valluna) habrían caído en poder de las poblaciones altiplánicas, convirtiéndose en colonias ("islas") de estas últimas, consolidando la estructura de "archipiélago vertical", con cabecera en el altiplano. De esta manera se habría dado forma a los archipiélagos étnicos Caranga, Quillaca y Lipes, que serían los más meridionales del mundo andino. Abstract in english The present work returns to the problem of the limits and limitations of the 'vertical archipelago', raised three decades ago by John V. Murra, and which still remains without a satisfactory solution. Rather than resolve the challenge left by Murra, / here offer a different approach to the archaeolo [...] gical information, which leads me to formulate a hypothesis that may guide the debate and search for answers within a wider context. Concentrating on the Western slopes of the Andes in the North of Chile, I propose that the model of the vertical archipelago, as defined by Murra, was consolidated only in the Late Intermediate Period. During the Middle Horizon, the need for vertical complementarity could have been resolved through the macro-system organized by Tiwanaku, a civilization that perfected the older "system of reticulated interaction " (Llagostera 2006), and did not depend on colonies for access to distant resources. But in the Late Intermediate Period, sociopolitical and environmental events combined to bring about a new form of organization in the Andean highlands and in the Western Valleys of the Pacific. In the latter, populations that had reached their sociocultural upper limit would have been restructured under mechanisms assimilable to those of 'duality'. Meanwhile the highland populations, afflicted by an intense drought, would have unleashed violent attacks against those living in the head-waters of the Western Valleys to get hold of their agricultural lands. Finally, the remnants of these pre-Andean populations (originally part of the valley dual organization) would have fallen into the hands of the altiplanic populations, becoming colonies ('islands') which consolidated a 'vertical archipelago structure' whose nuclei lay on the Altiplano. In this way were forme

  17. Resonant extended states in driven quasiperiodic lattices: Aubry-Andre localization by design

    Science.gov (United States)

    Morales-Molina, L.; Doerner, E.; Danieli, C.; Flach, S.

    2014-10-01

    We consider a quasiperiodic Aubry-Andre (AA) model and add a weak time-space-periodic perturbation. The undriven AA model is chosen to be well in the localized regime. The driving term controls the effective number of propagation channels. For a spatial resonance which reduces the reciprocal space dynamics to an effective one-dimensional two-leg ladder, the ac perturbation resonantly couples certain groups of localized eigenstates of the undriven AA model and turns them into extended ones. Slight detuning of the spatial and temporal frequencies off resonance returns these states into localized ones. We analyze the details of the resonant extended eigenstates using Floquet representations. In particular, we find that their size grows linearly with the system size. Initial wave packets overlap with resonant extended eigenstates and lead to ballistic spreading.

It is formed by 3 islands, all of volcanic origin: Masatierra (Robinson Crusoe), Masafuera (Alexander Selkirk) and Santa Clara. Johow and Skottsberg have made the most complete inventor [...] ies of the flora of this archipelago. The most recent study is the one of Danton & Perrier. The documented flora include 423 species of vascular plants, 55 Pteridophyta, 289 Dicotyledoneae and 79 Monocotyledoneae. Of the total number of species, 31.2% are endemic, 18.7% native and 50.1% introduced. The Poaceae family represents 11% of the total flora of the islands and displays 53 species included in 32 genera, of which 9,4% are endemic, 9,4% native and 81,2% alien. In this work a key for the genera and a description of the species are given. Information in relationship to the iconography, distribution, ecology, conservation and examined material is presented. These results are compared and discussed with the ones of Danton & Perrier (2006)

  2. SANS study of asphaltene aggregation

    International Nuclear Information System (INIS)

    The colloidal properties of asphaltenes affects their solubility, reactivity and transport properties. We have been investigating the molecular basis for the aggregation of asphaltenes in toluene through the use of Small Angle Neutron Scattering (SANS), in which the hydrogen nucleus provides the strongest scatterer, and the contrast may be varied by deuterium replacement. The measured intensity curves can be fitted with a elongated particle. Both radius of gyration and molecular weight are significantly decreased upon increasing temperature, indicating a disaggregation rather than a conformational change mechanism. Thus, the ''true'' molecular weight of asphaltenes is much less than that measured at room temperature, and appears to be ?6000. The internal structure is probably complex enough so that a simple description in terms of colloidal or micellar structures is not granted

  7. House mouse colonization patterns on the sub-Antarctic Kerguelen Archipelago suggest singular primary invasions and resilience against re-invasion

    Directory of Open Access Journals (Sweden)

    2010-10-01

    Full Text Available Abstract Background Starting from Western Europe, the house mouse (Mus musculus domesticus has spread across the globe in historic times. However, most oceanic islands were colonized by mice only within the past 300 years. This makes them an excellent model for studying the evolutionary processes during early stages of new colonization. We have focused here on the Kerguelen Archipelago, located within the sub-Antarctic area and compare the patterns with samples from other Southern Ocean islands. Results We have typed 18 autosomal and six Y-chromosomal microsatellite loci and obtained mitochondrial D-loop sequences for a total of 534 samples, mainly from the Kerguelen Archipelago, but also from the Falkland Islands, Marion Island, Amsterdam Island, Antipodes Island, Macquarie Island, Auckland Islands and one sample from South Georgia. We find that most of the mice on the Kerguelen Archipelago have the same mitochondrial haplotype and all share the same major Y-chromosomal haplotype. Two small islands (Cochons Island and Cimetière Island within the archipelago show a different mitochondrial haplotype, are genetically distinct for autosomal loci, but share the major Y-chromosomal haplotype. In the mitochondrial D-loop sequences, we find several single step mutational derivatives of one of the major mitochondrial haplotypes, suggesting an unusually high mutation rate, or the occurrence of selective sweeps in mitochondria. Conclusions Although there was heavy ship traffic for over a hundred years to the Kerguelen Archipelago, it appears that the mice that have arrived first have colonized the main island (Grande Terre and most of the associated small islands. The second invasion that we see in our data has occurred on islands that are detached from Grande Terre and were likely to have had no resident mice prior to their arrival. The genetic data suggest that the mice of both primary invasions originated from related source populations. Our data suggest that an area colonized by mice is refractory to further introgression, possibly due to fast adaptations of the resident mice to local conditions.

  8. Strukturelle studier af biomolekylære komplekser og syntetiske polymer systemer ved anvendelse af små-vinkel spredning, SANS og SAXS

    DEFF Research Database (Denmark)

    Mortensen, Kell

    Det er velkendt at krystallers velbeskrevne periodiske struktur giver anledning til interferens når Røntgen stråler sendes igennem materialet. Denne såkaldte ”Bragg spredning” blev teoretisk forklaret af William Lawrence Bragg og William Henry Bragg for 100 år siden, i 1913, på basis af observationer hvor de fandt at Røntgen stråler danner karakteristiske mønstre når de sendes gennem en krystal. Men Røntgen-bølgerne interfererer naturligvis også når de sendes gennem materialer som ikke er krystallinske, det kan være væsker, suspensioner eller amorfe systemer. Det mønster, som Røntgen-strålen danner, vil dog ikke have karakter af intense Bragg refleksioner, som kendes fra krystaller, men snarere have karakter af diffus spredning. Ligesom analyser af Bragg refleksionerne kan give detaljeret indsigt i krystallernes opbygning af molekyler og molekylernes indre struktur, kan detaljeret analyse af den diffuse spredning give indsigt i materialets atomare struktur. Røntgen stråling er den relevante type elektromagnetiske stråling, da bølgelængden på ca 1Å svarer til typiske atomare afstande. En anden type stråling med bølgelængde af samme størrelsesorden er neutron stråling. Men medens Røntgen strålingen i det væsentlige afhænger af hvordan elektronerne fordeles i materialet, er neutron-spredningen givet ved fordelingen af forskellige atom- kerner. Specielt gælder det at spredningen af neutroner fra brint-kernen generelt er meget forskellig fra spredningen fra andre atomer. Neutron spredning giver derfor ofte et billede af fordelingen af brint. Røntgen og neutron spredning er således komplementære teknikker som ’ser’ forskellige karakterer af den molekylære struktur. Den diffuse spredning måles i røntgen eller neutron diffraktometre. Der er specielt stor interesse for at studere strukturer på nano-skala niveau. Det kan være strukturen af proteiner og andre biomolekyler, strukturen af selv-organiserede systemer som den biologiske lipid-membran, mikro-emulsioner eller termoplastiske materialer. Med bølgelængder af størrelsesordenen Ångstrøm vil den diffuse spredning fra sådanne nano-skala strukturer komme meget tæt ved selve strålen. Der skal derfor måles ved meget små vinkler. Metoden til sådanne studier kaldes naturligt små-vinkel spredning (Small-Angle Scattering), hvoraf der finde de to primære metoder, SANS og SAXS med anvendelse af henholdsvis Neutron- og Røntgen-stråling (X-ray). I foredraget vil teknikkerne blive præsenteret og der vil blive vist eksempler på nuværende om kommende faciliteter. Der vil endvidere blive vist eksempler på hvordan kombination af SAXS og SANS kan benyttes til af give detaljeret strukturel indsigt i biomolekylære komplekser. Vi vil også vise hvordan teknikken kan bruges til at forstå og designe avancerede komplekse ordnede strukturer på nanometer længdeskala og hvordan mikro-reologien i komplekse væsker er et resultat af strukturelle ændringer

  9. Distribution and bioavailability of cadmium in ornithogenic coral-sand sediments of the Xisha archipelago, South China Sea

    International Nuclear Information System (INIS)

    Total cadmium (Cd) concentrations in four ornithogenic coral-sand sedimentary profiles displayed a strong positive correlation with guano-derived phosphorus, but had no correlation with plant-originated organic matter in the top sediments. These results indicate that the total Cd distributions were predominantly controlled by guano input. Bioavailable Cd and zinc (Zn) had a greater input rate in the top sediments with respect to total Cd and total Zn, and a positive correlation with total organic carbon (TOC) derived from plant humus. Multi-regression analysis showed that the total Cd and TOC explained over 80% of the variation of bioavailable Cd, suggesting that both guano and plant inputs could significantly influence the distribution of bioavailable Cd, and that plant biocycling processes contribute more to the recent increase of bioavailable Cd. A pollution assessment indicates that the Yongle archipelago is moderately to strongly polluted with guano-derived Cd. - Guano and plant biocycling processes can exert different influences on the distributions of total Cd and bioavailable Cd in coral-sand ornithogenic sediments.

  10. How Tourist Destinations Could Be Stereotyped and Misplaced by Structural Forces? - A Case of Penghu Archipelago, Taiwan

    2014-01-01

    Full Text Available Tourist destination image is important for strategic marketing and tourist choice. While many studies focus on images and their influencing factors, images are wrongly considered only for sale, compromising local authenticity and local life. With a critical review of development plans and the results of a questionnaire survey, this paper argues that images often stereotype and misplace tourist destination, in particularly for images brought about by structural forces. Islands are lands surrounded by ocean and often taken as full of marine and coastal resources and sceneries. In Penghu archipelago, marine environment is important for local livelihood and tourist destination. However, with the case of Erkan, we realize that, along with the evidence from interviews and surveys, most Erkan tourists do not come for its marine or natural resources. Erkan, as a fishing village, was turned into a tourism destination for tis vernacular architecture and folklore products irrelevant to its marine environment. With structural endeavours and official makeover of places, places are stereotyped and often become out of place.

  11. Large wood export regulated by the pattern and intensity of precipitation along a latitudinal gradient in the Japanese archipelago

    2012-03-01

    We examined the relationships between large wood (LW) export and precipitation patterns and intensity by analyzing the data on the annual volume of LW removed from 42 reservoirs and the daily precipitation at or near the reservoir sites. We also calculated the effective precipitation by considering the antecedent precipitation. Both daily and effective precipitation data were used as explanatory variables to explain LW export. The model selection revealed that the precipitation pattern and intensity controlling LW export varied with latitude in the Japanese archipelago. In small watersheds with narrow channel widths and low discharges, mass movements, such as landslides and debris flows, are major factors in the production and transport of LW. In this case, the effective precipitation required to initiate mass movements regulated the LW export and did not vary with the latitude. In intermediate and large watersheds with wide channel widths and high stream discharges, heavy rainfall and subsequent floods regulated buoyant depth, influencing the initiation of LW movement. In southern and central Japan, intense rainfall accompanied by typhoons or localized torrential downpours causes geomorphic disturbances, which introduce abundant pieces of LW into the channels. However, these pieces continue to be removed by repeated rainfall events. Therefore, LW export is supply-limited and potentially produces less LW accumulation. Conversely, in northern Japan, where typhoons and torrential downpours are rare, LW export is transport-limited because LW pieces recruited by bank erosion, tree mortality, and windthrow accumulate and persist on valley floors. These pieces may be easily exported by infrequent flooding.

  12. The Challenge of Nissology: A Global Outlook on the World Archipelago - Part II: The Global and Scientific Vocation of Nissology

    Full Text Available Islands are the rule and not the exception. One major objective for nissology – defined as the study of islands and islandness - in the 21st century should be to debunk the unfair prejudice that ‘island studies’ continues to suffer at present time. To do so, a systematic treatment of the island phenomenon needs to be undertaken and this should be backed up by substantial theoretical underpinnings. In seeking to turn the dominant continental paradigm on its head, islands not only deserve to be “studied on their own terms”; they also become the deus ex machina of a holistic understanding of the world archipelago and its ongoing globalization. This vision should contribute towards bridging the gap between ‘continentalists’ who tend to consider islands only as epiphenomena of larger land trends, and ‘island studies’ practitioners. This paper, the second of two segments, focuses mainly on the contribution of islands to global cultural and biological diversity, and concludes with an appeal for a more rigorous, pan-epistemic treatment of island studies.

    A high number of coral colonies, Montipora spp., with progressive tissue loss were reported from the north shore of Kaua'i by a member of the Eyes of the Reef volunteer reporting network. The disease has a distinct lesion (semi-circular pattern of tissue loss with an adjacent dark band) that was first observed in Hanalei Bay, Kaua'i in 2004. The disease, initially termed Montipora banded tissue loss, appeared grossly similar to black band disease (BBD), which affects corals worldwide. Following the initial report, a rapid response was initiated as outlined in Hawai'i's rapid response contingency plan to determine outbreak status and investigate the disease. Our study identified the three dominant bacterial constituents indicative of BBD (filamentous cyanobacteria, sulfate-reducing bacteria, sulfide-oxidizing bacteria) in coral disease lesions from Kaua'i, which provided the first evidence of BBD in the Hawaiian archipelago. A rapid survey at the alleged outbreak site found disease to affect 6-7% of the montiporids, which is higher than a prior prevalence of less than 1% measured on Kaua'i in 2004, indicative of an epizootic. Tagged colonies with BBD had an average rate of tissue loss of 5.7 cm2/day over a two-month period. Treatment of diseased colonies with a double band of marine epoxy, mixed with chlorine powder, effectively reduced colony mortality. Within two months, treated colonies lost an average of 30% less tissue compared to untreated controls. PMID:25774800

  14. Distinguishing between natural and aquaculture-derived sediment concentrations of heavy metals in the Broughton Archipelago, British Columbia

    International Nuclear Information System (INIS)

    Marine sediment samples were collected in the Broughton Archipelago, British Columbia, to assess the use of a geochemical normalization technique in the identification of a chemical tracer of aquaculture waste material. Zinc and copper were suggested as tracers of feed pellets, while copper was considered an indicator of anti-foulant agents used on netpen systems. The sediment samples were analyzed for carbon, nitrogen, organic matter, water, trace-element, and free sulfide concentrations, and sediment grain-size distribution. Sediment texture analysis revealed a wide range of substrate types from sand to silty loam categories. Strong relationships between sediment texture, sediment porosity, and organic content were observed across both near-field and far-field stations. Excess zinc and copper sediment concentrations, identified using a lithium-normalization technique, were restricted to near-field sampling stations (0 and 30 m from netpen systems). The relationships between these metal tracers and organic content and sulfur concentrations were explored to account for variations in sediment concentrations of zinc and copper

  15. Genetic variability and efficiency of DNA microsatellite markers for paternity testing in horse breeds from the Brazilian Marajó archipelago

    Full Text Available In this study, 15 microsatellite DNA loci used in comparative tests by the International Society for Animal Genetics were applied to the evaluation of genetic diversity and management, and the efficiency of paternity testing in Marajoara horses and Puruca ponies from the Marajó Archipelago. Based on [...] the genotyping of 93 animals, mean allelic diversity was estimated as 9.14 and 7.00 for the Marajoara and Puruca breeds, respectively. While these values are similar to those recorded in most European breeds, mean levels of heterozygosity were much lower (Marajoara 49%, Puruca 40%), probably as a result of high levels of inbreeding in the Marajó populations. The mean informative polymorphic content of this 15-marker system was over 50% in both breeds, and was slightly higher in the Marajoara horses. The discriminative power and exclusion probabilities derived from this system were over 99% for both populations, emphasizing the efficacy of these markers for paternity testing and genetic management in the two breeds.

  17. Silicic acid enrichment of subantarctic surface water from continental inputs along the Patagonian archipelago interior sea (41-56°S)

    2014-12-01

    We estimated Si?, the surplus or deficit of orthosilicic acid (DSi) relative to nitrate available for diatom growth, in the Chilean Patagonian Archipelago Interior Sea (PAIS). Si? and salinity were negatively correlated in the PAIS because of the mixing of high nitrate, low DSi subantarctic surface water and high DSi, low nitrate continental freshwater runoff. Both the slope and the intercept of this relationship decreased from northern to southern Patagonia, which was likely a consequence of reduced DSi inputs from several overlapping hydrological, biological and geological drivers along this gradient. In general, lower freshwater DSi concentrations were expected below 46°S, and a lower total DSi load was expected from reduced runoff below 51°S. The north-south decreasing DSi concentration trend may be linked to dilutions from a higher proportion of runoff in latitudes with higher precipitation rates (45-53°S), the transition to more resistant granitic rocks and glacial melt-water from the Northern and Southern Patagonia Ice Fields (46-51°S) and a reduced density of volcanoes active during the Holocene (48-56°S). The intensification of a southward DSi deficit may be a forcing factor involved in the reported southward reductions in plankton biomass and a more frequent occurrence of non-diatom blooms in southern PAIS.

  6. Sharp bounds on the radius of relativistic charged spheres: Guilfoyle's stars saturate the Buchdahl-Andr\\'easson bound

    2015-01-01

    Buchdahl, by imposing a few physical assumptions on the matter, i.e., its density is a nonincreasing function of the radius and the fluid is a perfect fluid, and on the configuration, such as the exterior is the Schwarzschild solution, found that the radius $r_0$ to mass $m$ ratio of a star would obey the Buchdahl bound $r_0/m\\geq9/4$. He noted that the bound was saturated by the Schwarzschild interior solution, the solution with $\\rho_{\\rm m}(r)= {\\rm constant}$, where $\\rho_{\\rm m}(r)$ is the energy density of the matter at $r$, when the central central pressure blows to infinity. Generalizations of this bound have been studied. One generalization was given by Andr\\'easson by including electrically charged matter and imposing that $p+2p_T \\leq\\rho_{\\rm m}$, where $p$ is the radial pressure and $p_T$ the tangential pressure. His bound is given by $r_0/m\\geq9/\\left(1+\\sqrt{1+3\\,q^2/r_0^2}\\right)^{2}$, the Buchdahl-Andr\\'easson bound, with $q$ being the star's total electric charge. Following Andr\\'easson's pr...

    The ancient book "Mozi" (5th century BC) records: "In ancient times, the San Miao tribes were in disarray. The sun rose in the evening...King Yu vanquished them. "King Yu is a prehistoric person living in 23-19th century BC. The strange phenomena "sun rose in evening" was explained as a large solar eclipse at sunset by Pang. Therefore investigations on it may lead to an important progress of Chinese chronology. After an analysis on all similar records in Chinese history, we pay main attention to the relationship of eclipse computations with parameter "c", the long term of earth's rotation rate. We have computed all the solar eclipses in that period by the way similar to that used for investigating the "double dawn" eclipse. By change parameter "c" in reasonable range (28-36 sec/cy2), we have found 11 possible results listed in a table. One figure shows the eclipse maps and relative "double dawn/dusk" areas while another one illustrates how the parameter "c" affects the result. For an exact conclusion of King Yu's chronology, we need further progress from both side: history which may limit the King Yu's period and astronomy which may limit the possible range of parameter "c".

  13. Compact High Resolution SANS using very cold neutrons (VCN-SANS)

    International Nuclear Information System (INIS)

    SANS (Small Angle Neutron Scattering) is a popular method for elucidation of nano-scale structures. However science continually challenges SANS for higher performance, prompting exploration of ever-more exotic and expensive technologies. We propose a compact high resolution SANS, using very cold neutrons, magnetic focusing lens and a wide-angle spherical detector. This system will compete with modern 40 m pinhole SANS in one tenth of the length, matching minimum Q, Q-resolution and dynamic range. It will also probe dynamics using the MIEZE method. Our prototype lens (a rotating permanent-magnet sextupole), focuses a pulsed neutron beam over 3-5 nm wavelength and has measured SANS from micelles and polymer blends. (authors)

  17. Periglacial Landscape Stabilization Following Rapid Permafrost Degradation by Thermo-erosion, Bylot Island, Nunavut, Canadian Arctic Archipelago

    The Byam Martin Mountains that run southeast-northwest across Bylot Island are covered by an ice cap which is flowing towards the lowlands into valleys. The bottom of these valleys is filled with sediments shaped into various periglacial landforms that developed during the Holocene such as ice-wedge polygons, pingos, and thermokarst lakes (Fortier and Allard, 2004). At the study site (N 73° 09’ - W 79° 53’), snow-melt run-off driven processes of thermo-erosion have recently drastically modified the periglacial landscape by creating extensive network of gullies in ice-wedge polygons. In the valley of glacier C-79, thirty five gullies, hundreds of meters to kilometers long, were identified and studied in the field. The formation of these gullies has changed the local hydrographic network by connecting the valley walls to a proglacial river flowing in the valley. The gully heads were characterized by active thermo-erosion processes operating underground and at the surface for a number of years (Fortier et al. 2007). Downstream, the gully walls were affected by various permafrost degradation processes such as active-layer detachment, retrogressive thaw slumping, drainage of the active layer of the polygons into the gully channel and differential thaw settlement of the surface (Godin and Fortier, 2010). It was observed that after a few years the downstream parts of the gully systems were stabilized and the gully walls partially colonized by vegetation. Drilling and coring operations into stabilized areas revealed the presence of ground ice a few decimeters below the surface with cryostructures indicative of permafrost aggradation. On stabilized gully walls, the sediments were aligned parallel to the slope and showed ice-rich reticulate to suspended cryostructures. Down to about one meter, the sediments were separated by centimeters-thick ice lenses which contained air bubbles aligned perpendicular to the slope. We propose that drainage of the soils on the slope and the subsequent colonization of stabilized slopes by vegetation changed the thermal properties of the soil which resulted in a thinning of the active layer and ground ice aggradation in the upper part of the permafrost. These negative feedback effects contributed to permafrost recovery and ground ice aggradation. The latent heat of this ice-rich zone will act as a buffer to global warming and contributes to the long-term stability of the gullies in the new periglacial landscape. Fortier, D., Allard, M. 2004.

    Sea ice is exchanged between the Arctic Ocean and Canadian Arctic Archipelago (CAA) but has not been quantified over long time periods. The corresponding mechanisms responsible for recent variability and change also remain unidentified. To address this, we estimated the sea ice area flux between the Arctic Ocean and the M'Clure Strait and Queen Elizabeth Islands (QEI) from 1997 to 2012 for the months of May to November. Over the period, there was a mean flux of -1 × 103 km2 (±21 × 103 km2) at the M'Clure Strait and mean flux of +8 × 103 km2 (±8 × 103 km2) at the QEI (positive and negative flux signs correspond to Arctic Ocean ice inflow and outflow, respectively). The M'Clure Strait had a mean flux of +5 × 103 km2 from May to September and a mean flux of -7 × 103 km2 from October to November. The QEI gates had a mean flux of +4 × 103 km2 from August to September with negligible ice exchange from May to July and October to November. More frequent high sea level pressure anomalies over the Beaufort Sea and Canadian Basin since 2007 have reduced Arctic Ocean multiyear ice (MYI) inflow into the M'Clure Strait. The presence of MYI in the CAA originating from the Arctic Ocean has been maintained by inflow at the QEI, which has increased since 2005. These recent increases in Arctic Ocean MYI inflow into the QEI can be attributed to increased open water area within the CAA that have provided more leeway for inflow to occur.

    Full Text Available An update is presented for fish species associated with spinner dolphins at Fernando de Noronha Archipelago, tropical Western Atlantic, providing a general view of their diversity. The associates are mostly reef-dwelling fishes that feed on the dolphin wastes. Twelve species are habitual or occasional plankton-eaters and two species are herbivores that occasionally forage on floating pieces of algae. One species is a strict carnivore, one species is a hitchhiker that forages on a variety of foods including parasites and dead tissue from the dolphins, and one species is a carnivore that joins the dolphin groups to forage on schools of small fishes or squids. We predict that the list of fish associated with spinner dolphins will expand mostly with addition of habitual or occasional plankton-eaters.Uma atualização é apresentada sobre as espécies de peixes associados a golfinhos-rotadores no Arquipélago de Fernando de Noronha, Atlântico Ocidental, fornecendo uma visão geral sobre sua diversidade. Os peixes associados são principalmente habitantes recifais que se alimentam de dejetos dos golfinhos. Doze espécies são planctófagas habituais ou ocasionais e duas são herbívoras que se alimentam ocasionalmente de algas à deriva. Uma espécie é carnívora estrita, uma vive fixada aos golfinhos e seu alimento é variado, incluindo parasitos e tecido morto dos golfinhos, e uma é carnívora que se junta aos grupos de golfinhos durante a caça a peixes e lulas. Prevemos que a lista de peixes associados a golfinhos-rotadores seja expandida principalmente com adição de planctófagos habituais ou ocasionais.

    This study presents the geomorphological and sedimentological analysis of a modern carbonate source-to-sink system located north of Madagascar (SW Indian Ocean). The sedimentary system is composed of an isolated carbonate platform sited on top of a seamount rising steeply from the seabed located at 3000 m water depth. The slope of the seamount is incised by canyons, and meandering channels occur above lobbed sedimentary bodies at the foot of the slope. The dataset consists of dredges, sediment piston cores, swath bathymetry and seismic (sparker and 2D high-resolution) lines collected from inner platform (less than 5 m deep) to the adjacent deep sedimentary basin. Particle size analysis and composition of carbonate grains are used to characterize the distribution and heterogeneity of sands accumulated on the archipelago. Main results show that composition of carbonate sediments is dominated by segments of Halimeda, large benthic foraminifera, coral debris, molluscs, echinoderms, bryozoans and sponges. According to the shape and the position of sandwaves and intertidal sandbars developed in the back-barrier reef, the present organization of these well-sorted fine-sand accumulations appears to be strongly influenced by flood tidal currents. Seismic lines acquired from semi-enclosed to open lagoon demonstrate that most of the sediment is exported and accumulated along the leeward margin of the platform, which is connected to a canyon network incising the outer slope. Following the concept of highstand shedding of carbonate platforms (Schlager et al., 1994), excess sediment is exported by plumes and gravity flows to the adjacent deep sea where it feeds a carbonate deep-sea fan. Combined observations from platform to basin allow to explain how the Glorieuses carbonate source to sink system has evolved under the influence of climate and of relative sea-level changes since the last interglacial.

    Juvenile pink salmon Oncorhynchus gorbuscha and chum salmon O. keta were sampled by beach or purse seine to assess levels of sea lice infestation in the Knight Inlet and Broughton Archipelago regions of coastal British Columbia, Canada, during the months of March to July from 2003 to 2012. Beach seine data were analyzed for sea lice infestation that was described in terms of prevalence, abundance, intensity, and intensity per unit length. The median annual prevalence for chum was 30%, ranging from 14% (in 2008 and 2009) to 73% (in 2004), while for pink salmon, the median was 27% and ranged from 10% (in 2011) to 68% (in 2004). Annual abundance varied from 0.2 to 5 sea lice per fish with a median of 0.47 for chum and from 0.1 to 3 lice (median 0.42) for pink salmon. Annual infestation followed broadly similar trends for both chum and pink salmon. However, the abundance and intensity of Lepeophtheirus salmonis and Caligus clemensi, the 2 main sea lice species of interest, were significantly greater on chum than on pink salmon in around half of the years studied. Logistic regression with random effect was used to model prevalence of sea lice infestation for the combined beach and purse seine data. The model suggested inter-annual variation as well as a spatial clustering effect on the prevalence of sea lice infestation in both chum and pink salmon. Fish length had an effect on prevalence, although the nature of this effect differed according to host species. PMID:23872858

    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. Acknowledgment This work is part of a PhD research project funded by the Regional Fund for Science and Technology of the Azores Regional Government (PhD scholarship M3.1.2/F/033/201).

    Full Text Available Feeding aspects of the oilfish, Ruvettus pretiosus, were studied based on 360 stomachs of both male and female specimens caught off the Saint Peter and Saint Paul Archipelago. The total length of the specimens ranged from 52.4 cm to 189.0 cm. Of the 360 stomachs examined, 135 presented some food and 225 were empty. Thirty-four taxa were identified, represented by 16 fish, 17 cephalopods and 1 crustacean. The stabilization of the food items richness was attained at 35 food items and 104 stomachs, approximately. A remarkable predation upon the flying fish Cheilopogon cyanopterus was observed around SPSPA, directly related to the main reproductive period of this species in the area. The oilfish's food spectrum shows that the species feeds on a wide vertical range in the water column, catching prey items at the surface or in shallow waters, as well as epi-mesopelagic fish, in addition to mesopelagic cephalopods.Aspectos alimentares do peixe-prego, Ruvettus pretiosus, foram estudados com base nos estômagos de 360 espécimes, de ambos os sexos, capturados nos arredores do Arquipélago de São Pedro e São Paulo.

    Traditional hard engineering structures and recently emerging soft engineering alternatives have been employed to protect vulnerable coastlines. Despite negative publicity, they have ensured community survival where socio-economic benefits outweigh adverse impacts. This is especially true for Small Islands (SI) where increasing sea levels and storm intensities threaten already limited land availability. This paper presents coastal vulnerability in São Miguel Island (the Azores SI archipelago) and considers SI issues with regard to coastal land loss. Regional wave statistics using 1998 to 2011 wind record showed: periods ranging from 7 to 13s (circa 83%); wave heights between 1 and 3m (circa 60%); and increasing trends in westerly (p=0.473), easterly (p=0.632) and southeasterly (p=0.932) waves. Sea level analyses between 1978 and 2007 indicated a statistically significant rising trend (2.5 ± 0.4 mm yr(-1); p=0.000), while between 1996 and 2007 it was 3.3 ± 1.5 mm yr(-1) (p=0.025), agreeing with other global sea level studies. Based on 2001 and 2008 population data and using zonal statistics, circa 60% of the Island's population was found to reside within 1 km of the sea and the percentage of total population was linearly correlated with distance from the shoreline (r(2)=99%). Three case studies show hard coastal engineering solutions preserved Azorean coastal lifestyle and had little or no observed negative impacts on their environs. Although hard engineering is likely to remain a valuable and feasible coastal protection option, an inventory of São Miguel's population distribution, surf breaks, bathymetry and coastal erosion rates showed the potential of using multifunctional artificial reefs as a soft engineering solution. These offshore submerged breakwaters offer coastal protection while providing additional benefits such as surfing amenity and beach widening. Consequently, findings of this work can inform other SI communities. PMID:24594743

    microstructural, and 40Ar/39Ar thermochronologic data from the Louisiade Archipelago, the southern rifted margin of the Woodlark Basin in SE Papua New Guinea, document an accretionary wedge that formed during Early-Middle Miocene N-dipping subduction of the Australian margin and transpression along the Australian-Pacific plate boundary. Metasedimentary rocks of the Calvados Schist and the metagabbros that intrude them were metamorphosed at up to greenschist-facies conditions. Three tectonic foliations (S1-S3) are present and F1-F3 fold hinges plunge ESE or WNW, parallel to mineral, stretching, and intersection lineations. Fold vergence is dominantly to the SW, and top-to-the-SW thrusting of ultramafic rocks over the Calvados Schist is documented locally on Rossel Island. The data suggest progressive deformation associated with NNE-SSW shortening and ESE-WNW extension via dissolution-precipitation creep and, more locally, dislocation creep. 40Ar/39Ar step-heating analyses of three white mica separates yield Middle Miocene plateau or plateau-like segments that are affected by variable Pliocene argon loss and are interpreted as syntectonic mica growth during metamorphism and deformation followed by partial resetting just prior to the onset of seafloor spreading in the Woodlark Basin. A ˜12 Ma 40Ar/39Ar age from a dacite sill of the Panarora Volcanics provides a minimum age constraint for the termination of northward subduction and a maximum age for crosscutting brittle strike-slip faults. These data are critical to constraining the subduction-exhumation history of the world's youngest high-ultrahigh-pressure terrane and further support analogies between SE Papua New Guinea and the Early Oligocene Western Alps.

    A study on tick fauna and tick-borne pathogens was undertaken in Pianosa, an island in the Tuscany Archipelago that constitutes an important stopping and nesting point for migratory birds. Ticks were removed from feral cats and a few terrestrial birds, and host-seeking ticks were collected by dragging. A total of 89 ticks were found on animals: 57 Ixodes ventalloi Gil Collado, 1936 and 32 Ixodes acuminatus Neumann, 1901. Host-seeking ticks were 354 Hyalomma spp. larvae and 18 Hyalomma spp. adults, identified as Hyalomma marginatum C.L. Koch, 1844 (n=11) and 7 Hyalomma detritum Schulze, 1919 (n=7). A sample of adult ticks was subjected to molecular analyses to look for Rickettsia spp. and Borrelia burgdorferi sensu lato (s.l.). Sequence analysis of the 5S-23S intergenic spacer region and OspA gene of B. burgdorferi s.l.-positive samples showed the presence of Borrelia spielmanii (n=3; 3.7%, 95% confidence interval [CI] 0.08-10.4) and Borrelia valaisiana (n=13; 13.6%, 95% CI 7.0-23.0) in Ixodes ticks from cats and terrestrial birds. Ixodes spp. were also infected by Rickettsia helvetica (n=19; 23.4%, 95% CI 14.7-34.2). Finally, we detected Rickettsia aeschlimannii in 3 out of 12 host-seeking Hyalomma spp. adults tested (25%, 95% CI 5.5-57.2). Our study shows the presence of several tick-borne pathogens in Pianosa. Hyalomma spp. and Ixodes ticks other than I. ricinus seem to be involved in their epidemiological cycle, and birds could contribute to the pathogen dispersal along their migration routes. This is the first finding of B. spielmanii in Italy. We hypothesize the involvement of peridomestic rodents or hedgehogs in its maintenance in Pianosa. PMID:23289398

    Full Text Available Record low mean September sea ice area in the Canadian Arctic Archipelago (CAA was observed in 2011 (146 × 103 km2, a level that was nearly exceeded in 2012 (150 × 103 km2. These values eclipsed previous September records set in 1998 (200 × 103 km2 and 2007 (220 × 103 km2 and are ?60% lower than the 1981–2010 mean September climatology. In this study, the driving processes contributing to the extreme light years of 2011 and 2012 were investigated, compared to previous extreme minima of 1998 and 2007, and contrasted against historic summer seasons with above average September ice area. The 2011 minimum was driven by positive July surface air temperature (SAT anomalies that facilitated rapid melt, coupled with atmospheric circulation in July and August that restricted multi-year ice (MYI inflow from the Arctic Ocean into the CAA. The 2012 minimum was also driven by positive July SAT anomalies (with coincident rapid melt but further ice decline was temporarily mitigated by atmospheric circulation in August and September which drove Arctic Ocean MYI inflow into the CAA. Atmospheric circulation was comparable between 2011 and 1998 (impeding Arctic Ocean MYI inflow and 2012 and 2007 (inducing Arctic Ocean MYI inflow. However, evidence of both preconditioned thinner Arctic Ocean MYI flowing into CAA and maximum landfast first-year ice (FYI thickness within the CAA was more apparent leading up to 2011 and 2012 than 1998 and 2007. The rapid melt process in 2011 and 2012 was more intense than observed in 1998 and 2007 because of the thinner ice cover being more susceptible to positive SAT forcing. The thinner sea ice cover within the CAA in recent years has also helped counteract the processes that facilitate extreme heavy ice years. The recent extreme light years within the CAA are associated with a longer navigation season within the Northwest Passage.

    In the far south of the Canadian Arctic Archipelago (CAA), on the Meta Incognita Peninsula (Baffin Island, Nunavut, Canada), the small Grinnell and Terra Nivea ice caps have received little attention compared to the much larger ice masses further north. Their evolution can, however, give valuable information about the impact of the recent Arctic warming at lower latitudes (i.e. 62.5° N). In this paper, we measure historical and recent rates of area, elevation and mass changes of both ice caps using in-situ, airborne and spaceborne datasets. Results show that the Terra Nivea Ice Cap (TNIC) areal extent has decreased by 34% since the late 50s, while the Grinnell Ice Cap (GIC) extent was reduced by 20% since 1952. For both ice caps, rates of area reduction accelerated at the beginning of the 21st century. The glacier-wide mass balance for the GIC was -0.37 ± 0.21 m a-1 water equivalent (w.e.) for the 1952-2014 period, and -0.47 ± 0.16 m a-1 w.e. on the TNIC for the 1958/59-2014 period. More recently, the TNIC has experienced an accelerated rate of mass loss of -1.68 ± 0.36 m a-1 w.e. between 2007 and 2014. This rate is 5.6 times as negative when compared to the 1958/59-2007 period (-0.30 ± 0.19 m a-1 w.e.) and 2 times as negative when compared to the mass balance of other glaciers in the southern parts of Baffin Island over the 2003-2009 period. A similar acceleration in mass loss is suspected for the GIC, given the calculated elevation changes and the proximity.

    Full Text Available Uma atualização é apresentada sobre as espécies de peixes associados a golfinhos-rotadores no Arquipélago de Fernando de Noronha, Atlântico Ocidental, fornecendo uma visão geral sobre sua diversidade. Os peixes associados são principalmente habitantes recifais que se alimentam de dejetos dos golfinh [...] os. Doze espécies são planctófagas habituais ou ocasionais e duas são herbívoras que se alimentam ocasionalmente de algas à deriva. Uma espécie é carnívora estrita, uma vive fixada aos golfinhos e seu alimento é variado, incluindo parasitos e tecido morto dos golfinhos, e uma é carnívora que se junta aos grupos de golfinhos durante a caça a peixes e lulas. Prevemos que a lista de peixes associados a golfinhos-rotadores seja expandida principalmente com adição de planctófagos habituais ou ocasionais. Abstract in english An update is presented for fish species associated with spinner dolphins at Fernando de Noronha Archipelago, tropical Western Atlantic, providing a general view of their diversity. The associates are mostly reef-dwelling fishes that feed on the dolphin wastes. Twelve species are habitual or occasion [...] al plankton-eaters and two species are herbivores that occasionally forage on floating pieces of algae. One species is a strict carnivore, one species is a hitchhiker that forages on a variety of foods including parasites and dead tissue from the dolphins, and one species is a carnivore that joins the dolphin groups to forage on schools of small fishes or squids. We predict that the list of fish associated with spinner dolphins will expand mostly with addition of habitual or occasional plankton-eaters.

    We investigated social structure and association patterns for a small population of Mediterranean bottlenose dolphins, Tursiops truncatus, inhabiting the Aeolian Archipelago (southern Italy). Specifically we evaluate the role of sex and age composition, residency patterns and interaction with trammel nets on this social organization. Association data for 23 regularly sighted individuals were obtained from summer photoidentification surveys collected from 2005-2012. Using a combined cluster and social network analysis approach, we found associations between dolphins were hierarchically structured, where two mixed-sex social units were subdivided into smaller temporarily dynamic groups. We found non-random and long-term preferred associations in the population; however, the degree of social cohesion, residence pattern and interaction with trammel nets differed considerably between the two social units. Six of eight females occurred in the more resident social unit-1; in addition, social unit-1 individuals had significantly stronger associations, higher preferred associates, lived in larger groups and occurred less frequently with trammel nets. Nine of eleven males were clustered in social unit-2 and five of these males, interacting with trammel nets, formed small groups and preferred associations. We propose that female and male groups associate in the study area during the breeding season and that some males choose to interact with reproductive females forming a distinct but interrelated social unit. Other males may be associating in a larger fission-fusion network, which consists of dolphins that appear to temporarily join the network from the coastal population. We cannot exclude that some males specialized in trammel net foraging, suggesting that this foraging technique may favor a solitary lifestyle. Large group sizes and high degree of social cohesion for females could be an indication of greater protection and more efficiency in detecting, deterring or repelling anthropogenic pressures. Most likely dolphins' social organization depends on a combination of socio-ecological, demographic and anthropogenic factors. PMID:25494331

  12. Gravity inversion for modelling of subsurface structures associated to the volcanic evolution of La Gomera island (Canarian Archipelago, Spain)

    It is firmly established that, of all the geodetic or geophysical techniques available, gravity modelling plays an important role in helping us to understand volcanic structures. We present here a study of the structural setting of the volcanic island of La Gomera by the analysis and interpretation of high-resolution gravity data obtained over the island. The gravity data allow us to model the main subsurface anomaly sources of the island, which are related with its volcanic evolution. Our outcome is consistent with the results of previous geophysical and volcanological studies. La Gomera island occupies a central position in the Canarian archipelago. This archipelago is the result of construction and destruction of successive large edifices covering a time span of several million years. Intrusion of magma has caused the development of an enormous amount of dikes that constituted step by step the main framework of the hypabyssal roots of these edifices. La Gomera has a surface about 372 km2 with a roughly circular contour and it is characterised by its central massif of 1487 meters height, dropping steeply to the sea. This island is the only one on the archipelago with no signs of Pleistocene volcanic activity. Its distinctive morphological feature is the intense degree of erosion in all formations, with deep, vertical-walled valleys that cut the island radially and in which the tabular successions of basalts can be seen. The most complex and interesting unit of La Gomera is its Basal Complex, which crops out in a restricted area located at the North and it is formed of plutonic volcanic and sedimentary rocks cut by an extremely dense dyke network. According to several authors, the characteristics of this complex seem to support the hypothesis that these rocks were formed by processes of magmatic sedimentation in a fairly turbulent medium. These conditions could correspond, for instance, to the ones in a reservoir beneath a volcano. Another possibility is that this basic and ultramafic complex could represent uplifted fragments of the deep crust or the upper mantle under the sea floor. The Basal Complex represents the submarine growth stage (the Submarine Edifice) and the hypabyssal roots of the different growth stages recorded in the island. Next, the first subaerial edifice was built up in two main stages. The first stage is represented by a large basaltic shield, of about 22 km in diameter, whose centre would be located near Vallehermoso Caldera (at the North of island) and would probably be extended some 5 km offshore the present northern coastline. Over the second growth stage an edifice of 25 km in diameter partly capped the earlier one. The second large edifice (the Young Edifice) emitted lava flows that covered up the central and southern areas of the island whilst they only filled deep ravines already excavated on the northern flank. The fact of La Gomera having an almost circular shape has traditionally been interpreted as the result of the built up of a single large volcanic edifice. However, the study of several authors about radial swarms of basic dikes shows that the island has gradually grown southwards but, because of the slow displacement of the magmatic focus, La Gomera does not display the N-S elongated shape which would be expected. In order to obtain a better knowledge about these volcanic and tectonic processes in the island, we have achieved a gravity survey to apply inversion techniques,which provide us a model of the crustal structures. The gravity data set, from the Institute of Astronomy and Geodesy (CSIC-UCM) and the Spanish National Geographic Institute, corresponds to 192 stations distributed over the whole island, although they are strongly conditioned by the sharp topography. Also, 899 marine gravity data from US Geological Survey have been used here. The obtained Bouguer anomaly map is analysed by means of a least squares prediction calculating a mean level of uncorrelated observational noise of 1.77 mGal. This anomaly is considered to obtain information about the distribution of mass den

  15. Generalisering og validering af model for afdrift af pesticider til læhegn og andre marknære biotoper

    Bruus, Marianne; LØfstrØm, Per

    2014-01-01

    I det netop afsluttede projekt ”Generalisering og validering af model for sprøjtemiddelafdrift til læhegn og andre marknære biotoper” har vi målt, hvor meget af det sprøjtemiddel, landmanden sprøjter ud, der ender i markens læhegn. Målingerne er anvendt til at videreudvikle og validere en model, der kan forudsige afdriften af de fleste sprøjtemidler under forskellige betingelser. Modellen kan tage hensyn til de givne egenskaber for pesticidet og til dysens dråbestørrelser, hvordan vejret er og om der er en sprøjtefri zone mellem traktoren og naturen uden for marken. Desuden kan modellen differentiere mellem forskellige højder i læhegn. Som forventet var afdriften til læhegn mindre ved brug af en luftinjektions-dyse end ved sprøjtning med fladsprede-dyse i den samme mark. Forskellen i afdrift mellem de to typer af dyser viser, at der er potentiale for, via valg af sprøjteudstyr, at reducere mængden af pesticider, der lander i læhegnene og dermed reducerer blomstring og frugtsætning. Samtidig viser såvel målinger som modelberegninger, at der ikke er den store effekt af sprøjtefrie bufferzoner på afdriften til læhegn, specielt ikke i den øverste del af læhegnene, hvor frugterne ofte er mest talrige.

    Full Text Available Storage replication is one of the back bones for network environments. While many forms of Network Attached Storage (NAS, Storage Area Networks (SAN and other forms of network storage exist, there is a need for a reliable storage replication technique between distant sites (> 1 Km. Such technology allows setting new standards and removes demerits of network failover and failback systems for virtual servers; specifically, the growing storage need for effective disaster recovery (DR planning. The purpose of this manuscript is to identify growing technologies such as IP-SAN that allow with remote storage cluster replication for virtual servers. This study (Cluster Replication provides an analysis of improving the uptime and availability of SAN. For higher levels of availability, mirrored images maintained in Active/Active Cluster mirroring can provide a system with No Single Points of Failure, which is designed to improve the overall uptime of the storage system for organizations with 7x24x365 requirements.

    A multi-purpose low-earth-orbit system of rings circling the earth - the "LEO ARCHIPELAGO" - is proposed as a means of solving or bypassing many major problems hindering man's quest to get into space. A fiber-optic ring about the earth would be an initial testing and developmental stage for the ring systems, while providing cash-flow through a LEO-based, high-band-width, world-wide communication system. A Low-Earth-Orbit-based space-elevator system, "Sling-on-a-Ring," is proposed as the crucial developmental stage of the LEO Archipelago. Being a LEO-based heavy-mass lifter, rather than earth- or GEO-based, it is much less massive and therefore less costly than other proposed space-elevators. With the advent of lower-cost, higher-mass transport to orbit, the options for further space development (e.g., communications, space solar power, radiation dampers, sun shades, and permanent LEO habitation) are greatly expanded. This paper provides an update of the Sling-on-a-Ring concept in terms of new materials, poten...

  5. Fatty acid profile of plasma, muscle and adipose tissues in Chilota lambs grazing on two different low quality pasture types in Chiloé Archipelago (Chile).

    There is no information about the effect of different pasture types on tissue fatty acid profiles of a native rustic lamb breed of the Chiloe Archipelago, the Chilota. Eight Chilota lambs were grazed on a 'Calafatal' pasture (CP), a typical secondary succession of Chiloé Archipelago (Chile) and eight Chilota lambs were located to graze on naturalized pasture (NP) of Chiloé. Botanical, chemical and lipid composition of the two types of pastures and of different lamb tissues (muscle, subcutaneous - and tail adipose tissues) and plasma were performed. Both pasture types induced high n-3 polyunsaturated fatty acids (PUFA) and CLAcis-9,trans-11 proportions in Chilota meat. Thus, in muscle, Chilota lambs grazing CP showed higher sum PUFA, sum n-6 PUFA proportion and n-6/n-3 PUFA ratio compared with Chilota lambs grazing NP. In tail fats of Chilota lambs grazing CP significantly higher proportions of 18:3n-3, sum saturated fatty acids, sum PUFA, n-3 and n-6 PUFA were detected compared with Chilota lambs grazing NP. Feeding of different pasture types (CP?vs.?NP) caused significant differences in fatty acid composition of muscle and the two fat depots in Chilota lambs, but also point to tissue-specific responses of de novo synthesized fatty acid deposition in the tissues.

  6. Systematic revision of Platanthera in the Azorean archipelago: not one but three species, including arguably Europe’s rarest orchid

    Richard M. Bateman

    2013-12-01

    Full Text Available Background and Aims. The Macaronesian islands represent an excellent crucible for exploring speciation. This dominantly phenotypic study complements a separate genotypic study, together designed to identify and circumscribe Platanthera species (butterfly-orchids on the Azores, and to determine their geographic origin(s and underlying speciation mechanism(s. Methods. 216 individuals of Platanthera from 30 Azorean localities spanning all nine Azorean islands were measured for 38 morphological characters, supported by light and scanning electron microscopy of selected flowers. They are compared through detailed multivariate and univariate analyses with four widespread continental European relatives in the P. bifolia-chlorantha aggregate, represented by 154 plants from 25 populations, and with the highly misleading original taxonomic descriptions. Physiographic and ecological data were also recorded for each study population. Key Results. Despite limited genetic divergence, detailed phenotypic survey reveals not one or two but three discrete endemic species of Platanthera that are readily distinguished using several characters, most floral: P. pollostantha (newly named, formerly P. micrantha occupies the widest range of habitats and altitudes and occurs on all nine islands; P. micrantha (formerly P. azorica occurs on eight islands but is restricted to small, scattered populations in laurisilva scrub; the true P. azorica appears confined to a single volcanigenic ridge on the central island of São Jorge. Conclusions. Although hybridity seems low, the excess of phenotypic over genotypic divergence suggests comparatively recent speciation. The most probable of several credible scenarios is that Azorean Platantheras represent a single migration to the archipelago of airborne seed from ancestral population(s located in southwest Europe rather than North America, originating from within the P. bifolia-chlorantha aggregate. We hypothesise that an initial anagenetic speciation event, aided by the founder effect, was followed by the independent origins of at least one of the two rarer endemic species from within the first-formed endemic species, via a cladogenetic speciation process that involved radical shifts in floral development, considerable phenotypic convergence, and increased mycorrhizal specificity. The recent amalgamation by IUCN of Azorean Platantheras into a single putative species on their Red List urgently requires overruling, as (a P. azorica is arguably Europe’s rarest bona fide orchid species and (b the almost equally rare P. micrantha is one of the best indicators of semi-natural laurisilva habitats remaining on the Azores. Both species are threatened by habitat destruction and invasive alien plants. These orchids constitute a model system that illustrates the general advantages of circumscribing species by prioritising field-based over herbarium-based morphological approaches.

    Full Text Available El archipiélago Juan Fernández (33°37'S, 78°51'W), es un grupo de islas situadas a 650 km al oeste de Chile continental, con alto grado de endemismo en su biota marina. A pesar de numerosas expediciones científicas a estas islas que han identificado este alto endemismo, pocos estudios han tratado de [...] identificar los patrones de estructura de la comunidad en hábitats submareales. Mediante censos visuales, se registraron los peces y su asociación con el hábitat en cinco sitios de estudio, en dos de las tres islas del archipiélago. Dado el aislamiento del archipiélago nos preguntamos: ¿Cuál es la composición de la fauna de peces de arrecife en estas aisladas islas? ¿Qué hábitats dominan los ambientes submareales? ¿Qué influye en la abundancia de peces de arrecife? Los análisis realizados sugieren que la comunidad de peces en el archipiélago está dominada por especies endémicas. La ictiofauna se compone de una mezcla de taxa de origen subtropical y templado, con una mayor similitud a las especies del Pacífico occidental que a las del Pacífico suroriental. Se identificaron diferentes ensambles de peces en sitios expuestos y protegidos. Las macroalgas pardas y rojas limitaron la abundancia de algunos peces de arrecife. Cuatro categorías tróficas de peces de arrecife, estuvieron presentes en el archipiélago, siendo los invertívoros los consumidores dominantes.

Using visual census, we surveyed fish and habitat associations at five sites located at two of the three islands of the archipelago. Given the isolation of the archipelago we asked: What is the composition of the reef fish fauna at these isolated islands? What habitats dominate subtidal environments? What influences the abundances of reef fishes? Our analysis confirms that fish communities at the archipielago are dominated by endemic species. The ichthyofauna is comprised of a mixture of subtropical and temperate taxa, with greater similarity to western than eastern South Pacific fauna. We identified different fish assemblages at wave-exposed and wave-sheltered sites. Brown and red macroalgae were correlated with the abundances of some reef fishes. Four broad trophic categories of reef fishes were present at the archipelago, with invertebrate consumers dominating abundance. To our knowledge, this is the first attempt to quantify patterns of community structure in subtidal environments at the Juan Fernández Archipelago.

The extracts were incorporated in paper discs and it was verified the effect on the human pathogenic bacteria growth. The tested bacteria were Staphylococcus aureus (ATCC [...] 6538), Escherichia coli (ATCC 11129) and Pseudomonas aeruginosa (ATCC 9027). The crude ethanolic extract, the ethyl acetate and the remained ethanolic fractions showed growth inhibition of S. aureus, only the crude ethanilic extract showed, in lower extension, growth inhibition of P. aeruginosa and no growth inhibition at all of E. coli. The phytochemical screening indicated the presence of tannins, leucoanthocianidins, flavonoids and triterpene/steroids.

  18. Low levels of 134Cs and 137Cs in bottom sediments along the Japanese Archipelago side of the Sea of Japan after the Fukushima Dai-ichi NPP accident

    International Nuclear Information System (INIS)

    We examined radiocesium concentrations in bottom sediment samples collected along the Japanese Archipelago side of the Sea of Japan before/after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident. Low levels of 134Cs were detected in an area located near estuaries. This was considered to be due to the riverine discharge rather than direct radioactive depositions to sea surface. (author)

  19. Polarimetric C-/X-band Synthetic Aperture Radar Observations of Melting Sea Ice in the Canadian Arctic Archipelago

    Operational ice information services rely heavily on space-borne synthetic aperture radar (SAR) data for the production of ice charts to meet their mandate of providing timely and accurate sea ice information to support safe and efficient marine operations. During the summer melt period, the usefulness of SAR data for sea ice monitoring is limited by the presence of wet snow and melt ponds on the ice surface, which can mask the signature of the underlying ice. This is a critical concern for ice services whose clients (e.g. commercial shipping, cruise tourism, resource exploration and extraction) are most active at this time of year when sea ice is at its minimum extent, concentration and thickness. As a result, there is a need to further quantify the loss of ice information in SAR data during the melt season and to identify what information can still be retrieved about ice surface conditions and melt pond evolution at this time of year. To date the majority of studies have been limited to analysis of single-polarization C-band SAR data. This study will investigate the potential complimentary and unique sea ice information that polarimetric C- and X-band SAR data can provide to supplement the information available from traditional single co-polarized C-band SAR data. A time-series of polarimetric C- and X-band SAR data was acquired over Jones Sound in the Canadian Arctic Archipelago, in the vicinity of the Grise Fiord, Nunavut. Five RADARSAT-2 Wide Fine Quad-pol images and 11 TerraSAR-X StripMap dual-pol (HH/VV) images were acquired. The time-series begins at the onset of melt in early June and extends through advanced melt conditions in late July. Over this period several ponding and drainage events and two snowfall events occurred. Field observations of sea ice properties were collected using an Ice Mass Balance (IMB) buoy, hourly photos from a time-lapse camera deployed on a coastal cliff, and manual in situ measurements of snow thickness and melt pond depth. Where available, clear-sky data from optical sensors (MODIS, Landsat-8, and WorldView) are also used to provide supplementary information on melt pond coverage and evolution. Meteorological data are available from an Environment Canada weather station in Grise Fiord. In this presentation we will discuss the sea ice information provided by each polarization and frequency and evaluate the impact of melt pond evolution on SAR backscatter. Results to date indicate that C- and X-band provide predominantly redundant information, and cross-polarized backscatter (only acquired at C-band) is often very low and near the system noise floor. Early in the melt season a thick wet snow pack is present and both frequencies provide very little ice information. This is attributed to the strong attenuation of the microwave signal by the wet snow. At this time the underlying ice is effectively obscured. During heavily ponded periods backscatter is highly variable, attributed to changing winds and thus variable melt pond surface roughness. In the final week of observations the fast ice in the region is breaking up and open water is present in some images. In these images C-band appears to provide greater contrast between the melting ice and open water than X-band. Analysis of polarimetric parameters is ongoing.

    Full Text Available Se analizaron los resultados de un modelo oceánico regional (ROMS), combinado con información de clorofila-? (Clo-?) y altimetría satelital, además de información proveniente de cruceros oceanográficos, para identificar la interacción entre los remolinos intratermoclina (ITEs) y el Archipiélago Juan [...] Fernández (AJF), y discutir su potencial impacto sobre las concentraciones de Clo-? superficial. El AJF se encuentra ubicado frente a la costa central de Chile (33°S), y está conformado por las islas Robinson Crusoe, Santa Clara y Alejandro Selkirk. Los resultados indican que los remolinos anticiclónicos superficiales y subsuperficiales que interactúan con el AJF se forman principalmente en la zona de transición costera entre 33° y 39°S. Los ITEs se presentan en la región del AJF con una frecuencia semianual, principalmente durante el período de otoño austral, y poseen una débil expresión superficial respecto de los remolinos superficiales adyacentes, un lento desplazamiento (1,16-1,4 km d-1) con dirección noroeste y una estructura coherente por períodos ? 1 año. Durante la interacción de los ITEs con las islas RC-SC y el monte submarino adyacente, se observó una leve (prominente) deflexión del límite superior (inferior) de la termoclina. La escala horizontal (~70-100 km) fue mayor que el radio interno de deformación de Rossby y la escala vertical promedio fue de ~400 m. La interacción entre el ITE de débil expresión superficial identificada con altimetría satelital durante el período de otoño y el AJF perduró durante nueve semanas alcanzando el período invierno. Aproximadamente un mes después del comienzo de la interacción entre el ITE y las islas, se observaron incrementos de Clo-? superficial asociados al remolino con valores hasta tres veces mayores, respecto de las aguas oceánicas adyacentes. Abstract in english Regional Ocean Modeling System (ROMS) results, combined with chlorophyll-? (Chl-?) and satellite altimetry information as well as information from oceanographic cruises were analyzed to identify interactions between intrathermocline eddies (ITEs) and the Juan Fernández Archipelago (JFA), and discuss [...] their potential impact on surface Chl-? concentrations. The JFA is located off the coast of central Chile (33°S), and is composed of three main islands: Robinson Crusoe (RC), Alejandro Selkirk (AS) and Santa Clara (SC). Results indicate that the surface and subsurface anticyclonic eddies that interact with the JFA are formed primarily within the coastal transition zone between 33° and 39°S. ITEs are present within the JFA region with a semiannual frequency, mainly during the austral autumn, and have a weak surface expression in relation to the adjacent surface eddies, with a slow displacement (1.16 to 1.4 km d-1) in a northwest direction and a coherent structure for periods of ? 1 year. During the ITEs' interaction with RC-SC islands and an adjacent seamount, a slight (prominent) thermocline deflection of the upper limit (lower) was observed. The horizontal extent (~70-100 km) was greater than the internal Rossby deformation radius and the average vertical extent was ~400 m. The interaction between the weak surface expression of ITEs, identified with satellite altimetry, and the JFA persisted during autumn for nine weeks until reaching the winter period. Approximately one month after the beginning of the interaction between ITEs and the islands, increases in surface Chl-? associated with the eddy were observed, with values up to three times higher than adjacent oceanic waters.

  1. A little island with significant groundwater resources: hydrogeological and hydrogeochemical features of the Pianosa aquifer (Tuscan Archipelago, Italy)

    The Pianosa Island is one of the seven islands of the Tuscan Archipelago, particularly known for its typical flat morphological structure. It is formed by Neogenic-Quaternary sedimentary rocks, mainly represented by superficial calcarenite and underlying marl and clayey marl. Despite the small extension of the island (just 10,2 km2 wide, coastal perimeter of approximately 18 km, maximum altitude of 29 m a.s.l.) and poor rainfall amount (the annual average is 480,7 mm in 1951-2002 period), the Pianosa aquifer is characterized by significant groundwater resources, which supported the presence of approximately 2,000 people at the end of Eighties. Nevertheless, the groundwater overexploitation and the land use (agricultural activity and cattle-breeding, associated to the local penal settlement activity) caused important sea-water intrusion and pollution phenomena. An improvement of such situation occurs since 1998, owing to the closing of the penal settlement and its activities. This pilot research intends to describe the hydrogeological and hydrogeochemical features of the Pianosa Island aquifer system and the groundwater quality several years after the penal settlement closing. The results of a multidisciplinary approach (hydrogeological, geochemical, isotopic) show that the groundwater recharge and circulation are substantially controlled by the hydro-structural conditions. The flat and permeable superficial calcarenite allows a high infiltration rate. The water table flow direction is generally W-E, in accordance with the dip direction of the stratigraphic contact between the calcarenite and the underlying impermeable marly-clayey rocks. However, the latter present conglomerate and sandstone intercalations, sometimes in contact (by angular unconformity) with the calcarenite, determining a general continuity in groundwater circulation, which is phreatic in the calcarenite, and confined in the conglomerate and sandstone horizons. A piezometric depression with values below the sea level has been identified in the eastern part of the island. The electric conductivity (EC) map confirms this hydrogeological structure. EC values above 1.000 ?S/cm are common in almost all the groundwater analyzed. An increase in groundwater salinity is observable in the eastern part of Pianosa, where the water table depression has been recognized. In agreement with the hydro-structural and water table conditions, the hydrogeochemical analyses confirm the recharge of the confined horizons (conglomerate and sandstone) by the superficial calcarenite. The isotopic data indicate that the aquifer system is recharged by the rainfall direct infiltration and there are not connections with the close Elba Island. Finally, the chemical analyses of most groundwater samples suggest an intermediate facies Na-Cl/Ca-HCO3, produced by the combination of the sea spray and the circulation in a prevalently carbonate aquifer (calcarenite). Clearly Na-Cl groundwater prevails in the eastern portion of the island, evidencing the seawater intrusion in the calcarenite, also confirmed by water table conditions and isotopic data.

    Full Text Available The spotted sand bass (Paralabrax maculatofasciatus is an important recreational sport and subsistence food fish within San Diego Bay, a large industrialized harbor in San Diego, California. Despite this importance, few studies examining the species life history relative to pollutant tissue concentrations and the consumptive fishery exist. This study utilized data from three independent spotted sand bass studies from 1989 to 2002 to investigate PCB, DDT, and mercury tissue concentrations relative to spotted sand bass age and growth in San Diego Bay, with subsequent comparisons to published pollutant advisory levels and fishery regulations for recreational and subsistence consumption of the species. Subsequent analysis focused on examining temporal and spatial differences for different regions of San Diego Bay. Study results for growth confirmed previous work, finding the species to exhibit highly asymptotic growth, making tissue pollutant concentrations at initial take size difficult if not impossible to predict. This was corroborated by independent tissue concentration results for mercury, which found no relationship between fish size and pollutant bioaccumulation observed. However, a positive though highly variable relationship was observed between fish size and PCB tissue concentration. Despite these findings, a significant proportion of fish exhibited pollutant levels above recommended state recreational angler consumption advisory levels for PCBs and mercury, especially for fish above the minimum take size, making the necessity of at-size predictions less critical. Lastly, no difference in tissue concentration was found temporally or spatially within San Diego Bay.

  4. San Rafael mining and fabrication complex today

    International Nuclear Information System (INIS)

    In Mendoza province, 35 km West San Rafael city, is located a CNEA installation for uranium ore extraction and concentration: the San Rafael Mining and Fabrication Complex. By the middle of the nineties, as a consequence of the very low prices of uranium concentrate in the international market and of the high internal production costs, uranium extraction was stopped. To day, the international price of the concentrate had a very important increase and the Government has decided the completion of the Atucha II Nuclear Power Station construction. Moreover, studies have been started for new nuclear power plants. In such circumstances the reactivation of the Complex will make sure the uranium supply for our nuclear power stations, contributing to the improvement of the energy generation mix in our country.

  5. Role of the Deep Mantle in Generating EM-I in Ocean Island Basalts: Insight from the Kerguelen Archipelago (Indian Ocean) (Invited)

    Weis, D.

    2013-12-01

    The Kerguelen Plume is responsible for one of the longest (both in length and time) hotspot tracks on Earth, starting at ~120 Ma with the formation of the Rajmahal Traps in India. The tectonic setting evolved from continental break-up at ~120 Ma, to a position above the Southeast Indian Ridge (SEIR) at ~40 Ma, to a purely oceanic environment today. The Cretaceous record of volcanism on the Central and Southern Kerguelen Plateau shows interaction of mantle plume-derived magmas with continental-related material (5000 km-long Ninetyeast Ridge (82-38 Ma) lacks any evidence of such shallow contamination. Upper mantle components (depleted, SEIR-type) participated in the formation of the submarine Northern Kerguelen Plateau (~34 Ma). The Kerguelen Archipelago is covered (>80%) by flood basalts erupted between 30 and 24 Ma. With decreasing age and increasing distance from the SEIR, the compositions evolved from tholeiitic in the northwest, to transitional in the central part of the archipelago, and to alkaline in the Southeast Province. The transition from tholeiitic to mildly alkalic compositions primarily reflects changes in melting conditions (lower extents of partial melting at higher pressures), associated with crust and lithosphere thickening as the distance from the SEIR increased. High-precision Pb-Sr-Nd-Hf isotopic data reveal that the archipelago flood basalts were derived from melting of an enriched component (EM-I) in the plume source, without any trace of continental contamination during eruption. The enriched component dominates the chemistry of the alkalic basalts (25-24 Ma), whereas the older (28-26 Ma) tholeiitic-transitional basalts contain a higher proportion of a depleted-SEIR component. In binary isotope plots, Kerguelen compositions form subparallel trends that are distinctly more enriched than those from Hawaii. Seismic data shows the presence of two large-low-shear-velocity-provinces (LLSVP) in the deep mantle, one centred in the Pacific, the other below Africa. When projected down to the core-mantle boundary (CMB), Kerguelen and Tristan (Atlantic Ocean) are located on the eastern and western edges of the tall steep-sided LLSVP African anomaly, respectively. The other two islands with EM-I signatures, Hawaii and Pitcairn, overlie the edges of the Pacific LLSVP. We infer that these deep zones with velocity anomalies at the CMB are the repositories for enriched components in the mantle that are brought to the surface by strong mantle plumes. Kerguelen and Tristan carry the strongest enriched signature, also referred to as the ';DUPAL anomaly', whereas Pitcairn and Hawaii have a distinct, slightly less pronounced enriched signature. The differences in EM-I compositions indicate that some of the material constituting the LLSVP at the base of the mantle is different in the African and Pacific anomalies. In Hawaii, the EM-I signature can be traced back to at least 5 Ma, whereas in Kerguelen it can be traced back until 34 Ma on the archipelago and Northern Kerguelen Plateau, and until 82 Ma along the Ninetyeast Ridge. This implies that the LLSVPs are long-lived features of the deep mantle; in the case of the African anomaly, on the order of 100 million years.

    The scorpion of Montecristo Island (Tuscan Archipelago, Italy): Euscorpius carpathicus oglasae Di Caporiacco, 1950, is a poorly known taxon. We redescribe and illustrate the insular endemism of E. c. oglasae for the first time, and elevate this subspecies to the rank of species following a thorough study of the comparative morphology of 372 specimens (including 7 related taxa). Euscorpius oglasae stat. nov. is an oligotrichous form that differs from the related species by the inner proximal surface of pedipalp movable finger, with a reduced lobe and a slightly swollen telson vesicle in males. Attention was given to the analysis of the hemispermatophore and peg sensilla of pectens. The hemispermatophore is small, with the basal lobe bearing a very short spine. We also discuss aspects of the ecology, conservation and biogeography of this species. PMID:17303538

    2007-01-01

    Introduction The population of the San Luis Valley region is growing rapidly. The shallow unconfined and the deeper confined Santa Fe Group aquifer in the San Luis Basin is the main sources of municipal water for the region. Water shortfalls could have serious consequences. Future growth and land management in the region depend on accurate assessment and protection of the region's ground-water resources. An important issue in managing the ground-water resources is a better understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits that fill the Rio Grande rift, which contain the principal ground-water aquifers. The U.S. Geological Survey (USGS) is conducting a series of multidisciplinary studies of the San Luis Basin located in southern Colorado. Detailed geologic mapping, high-resolution airborne magnetic surveys, gravity surveys, an electromagnetic survey, called magnetotellurics (MT), and hydrologic and lithologic data are being used to better understand the aquifer systems. The primary goal of the MT survey is to map changes in electrical resistivity with depth that are related to differences in rock type. These various rock types help control the properties of aquifers in the region. This report does not include any interpretation of the data. Its purpose is to release the MT data acquired at the 22 stations shown in figure 1.

This report does not include any data interpretation. Its purpose is to release the MT data acquired at 24 stations. Two of the stations were collected near Santa Fe, New Mexico, near deep wildcat wells. Well logs from those wells will help tie future interpretations of this data with geologic units from the Santa Fe Group sediments to Precambrian basement.

  16. San Andreas Fault tremor and retrograde metamorphism

    Fagereng, Åke; Diener, Johann F. A.

    2011-12-01

    Tectonic tremor is an enigmatic low-frequency seismic phenomenon mainly observed in subduction zones, but also documented along the deep extension of the central San Andreas Fault. The physical mechanisms behind this unusual seismic event are not yet determined for any tectonic setting; however, low effective stress conditions arising from metamorphic fluid production are commonly inferred for subduction-related tremor. We investigate the petrologic conditions at which the San Andreas tectonic tremor is inferred to occur through calculations of the pressure - temperature - time evolution of stable mineral assemblages and their water content in the dominant lithologies of the Franciscan Complex. We find that tremor locations around Parkfield and Cholame are currently experiencing retrograde metamorphic conditions. Within the temperature-depth conditions of observed tremor activity, at approximately 500°C and 20 km depth, several mineralogical transitions may occur in cooling greywacke and mafic rocks, leading to localised, significant removal of free water and an associated volume decrease. This indicates that, contrary to subduction-related tremor, tremor on the San Andreas Fault is not linked to prograde, crustal metamorphic fluid production within the fault zone; rather it might be related to mantle-derived fluids from below the tremor zone, and/or fault zone weakening that occurs as phyllosilicates replace more competent and granular mineral phases.

The objective of the present work is to investigate the impact of the avifauna on landscape evolution at the Abrolhos Archipelago, based on soils chemical characteristics and spatial distribution. A total of 10 soil profiles are described and analyzed, representing the main landscape units present in the Archipelago. Based on careful field observation and interpretation made on the existing nautical map (n.1311, produced by the Brazilian Navy (scale 1:100.000, detailed soil maps were produced. The widespread occurrence of strongly ornithogenic soils in areas without current nesting activity indicates a much broader occupation by birds in the past. Some of the studied soils are of difficult classification, and reflect the marked influence of present-day and past avifauna activity.

Com base em observação de campo e interpretação de carta náutica da Marinha do Brasil (n. 1311), em escala 1:100.000, foi produzido o mapa de solos das ilhas. A presença generalizada de solos fortemente ornitogênicos, em áreas sem nidificação atual ou com fraca nidificação, indica uma ocupação pretérita por aves bem mais ampla que a atual. Alguns solos estudados em Abrolhos são de difícil classificação e refletem influência marcante da avifauna, atual ou pretérita. Abstract in english The activity of the avifauna on terrestrial ecosystems results in the intense chemical and mineralogical alteration of mineral substrates. The objective of the present work is to investigate the impact of the avifauna on landscape evolution at the Abrolhos Archipelago, based on soils chemical charac [...] teristics and spatial distribution. A total of 10 soil profiles are described and analyzed, representing the main landscape units present in the Archipelago. Based on careful field observation and interpretation made on the existing nautical map (n.1311), produced by the Brazilian Navy (scale 1:100.000), detailed soil maps were produced. The widespread occurrence of strongly ornithogenic soils in areas without current nesting activity indicates a much broader occupation by birds in the past. Some of the studied soils are of difficult classification, and reflect the marked influence of present-day and past avifauna activity.

  20. Development of 40m SANS and Its Utilization Techniques

    International Nuclear Information System (INIS)

    Small angle neutron scattering (SANS) has been a very powerful tool to study nanoscale (1-100 nm) bulk structures in various materials such as polymer, self assembled materials, nano-porous materials, nano-magnetic materials, metal and ceramics. Understanding the importance of the SANS instrument, the 8m SANS instrument was installed at the CN beam port of HANARO in 2001. However, without having a cold neutron source, the beam intensity is fairly low and the Q-range is rather limited due to short instrument length. In July 1, 2003, therefore, the HANARO cold neutron research facility project was launched and a state of the art 40m SANS instrument was selected as top-priority instrument. The development of the 40m SANS instrument was completed as a joint project between Korea Advanced Institute of Science and Technology and the HANARO in 2010. Here, we report the specification of a state of art 40m SANS instrument at HANARO

    The recovery of the biogas generated from sanitary landfills, associated to its energetic use has been widely discussed. Thus, this paper aims to estimate the potential production of electric energy from sanitary landfill Santo Andre-SP. The biogas production was estimated using the rate of deposition of solid wastes in the landfill, using some mathematical models with parameters suggested by two models: LanGEM-USEPA (conventional landfill) and Word Bank. These results indicate that the potential of biogas production will be approximately 11 x 10{sup 6} Kg of methane/year in 2017 and production of electric energy in that year will be approximately 32,000 MWh, considering an of 75% over collection of biogas.

    The San Francisco Bay and Sacramento-San Joaquin Delta form one of the largest estuaries in the United States. The “Bay-Delta” system provides water to more than 25 million California residents and vast farmlands, as well as key habitat for birds, fish, and other wildlife. To help ensure the health of this crucial estuary, the U.S. Geological Survey, in close cooperation with partner agencies and organizations, is providing science essential to addressing societal issues associated with water quantity and quality, sediment transportation, environmental contamination, animal health and status, habitat restoration, hazards, ground subsidence, and climate change.

  3. Arsenic in benthic bivalves of San Francisco Bay and the Sacramento/San Joaquin River Delta.

    Johns, C; Luoma, S N

    1990-11-01

    Arsenic concentrations were determined in fine-grained, oxidized, surface sediments and in two benthic bivalves, Corbicula sp. and Macoma balthica, within San Francisco Bay, the Sacramento/San Joaquin River Delta, and selected rivers not influenced by urban or industrial activity. Arsenic concentrations in all samples were characteristic of values reported for uncontaminated estuaries. Small temporal fluctuations and low arsenic concentrations in bivalves and sediments suggest that most inputs of arsenic are likely to be minor and arsenic contamination is not widespread in the Bay.

    Rheumatoid arthritis (RA) is an autoimmune joint disease. We evaluated a standard preparation of Lingzhi (Ganoderma lucidum) and San-Miao-San (Rhizoma atractylodis, Cortex phellodendri, Radix achyranthes bidentatae) capsules (TCM group) for its supplementary treatment efficacy for RA. There was no significant difference in the absolute count, percentage, and ratios of CD4(+)/CD8(+)/natural killer/B lymphocytes between the TCM and placebo groups after taking the capsules (all p > 0.05). There was no significant change in concentrations of plasma cytokines of interferon-gamma-induced protein-10 (IP-10), monocyte chemoattractant protein-1, monokine induced by IFN-gamma, regulated upon activation normal T-cell expressed and secreted, interleukin (IL)-8, and IL-18 after taking the capsules for 8 and 24 weeks (all p > 0.05). The percentage change in ex vivo-induced level of inflammatory cytokine IL-18 was significantly lower in the TCM group than in the placebo group after taking the capsules for 24 weeks (p Lingzhi and San-Miao-San capsules might exert a beneficial immunomodulatory effect in patients with rheumatoid arthritis.

  7. Er nogen mere lige end andre? : en socioøkonomisk undersøgelse af Restgruppens uddannelses - og arbejdslivsmuligheder

    DEFF Research Database (Denmark)

    MØberg, Rasmus Juul

    2010-01-01

    En underliggende argumentation i afhandlingen er, at risici i stigende grad individualiseres, dog uden at risici er demokratiske. Den stigende individualisering i uddannelsessystemet og tilknytningen til arbejdsmarkedet skjuler livsforløbets multidimensionalitet. Der eksisterer et institutionelt setup omkring livsforløbet der – i visse tilfælde – rækker udover den enkelte persons indflydelse. Selv forandringer og forløb, der oprindeligt er initieret af den enkelte selv, kan få vidtrækkende konsekvenser, der ikke umiddelbart kan overkommes af den enkelte selv. Et flexicurity-perspektiv der medvirker til at gøre differentierede arbejdslivsmuligheder mindre synlige. Disse skjulte skævvridninger er genstand for diskussion i afhandlingen. Flexicurity-tilgangen har for mig at se ikke tilstrækkelig blik for arbejdsstyrken heterogenitet, mangfoldigheden i livsforløbets institutionelle setup og (arbejds)livsforløbets dynamiske karakter. Flexicurity-firkanten er en diskussion, der primært er orienteret imod hovedstrømninger af arbejdskraften på arbejdsmarkedet, og er i den henseende orienteret mod et makroniveau. Pointen med afhandlingens arbejde er at kigge dybere og fokusere på mikro- og mesoniveau for at få en større indsigt i påvirkningen fra disse niveauer med henblik på en diskussion af arbejdslivsmuligheder for udsatte grupper på arbejdsmarkedet – specielt uddannelsessystemets Restgruppe. Denne anderledes tilgang er umiddelbart nødvendig i forhold til at indfange de fordelingspolitiske konsekvenser struktureringen af arbejdsmarkedet har. I afhandlingen har jeg primært beskæftiget mig med arbejdsgivernes indvirkning på struktureringen af det enkelte livsforløb, den enkeltes uddannelsesforløb (ungdomsuddannelse og deltagelse i VEU), familiemæssige forhold – herunder intergenerationelle forholds betydning – samt konjunkturelle forhold. Det er således et særligt snit, der er lagt i afhandlingen, men det analytiske potentiale skulle gerne fremgå af de foregående sider i afhandlingen. Det er ikke kun indtrædelse på arbejdsmarkedet, der er placeret i ungdomsårene, der er det aldersmæssige tidsspan, afhandlingen behandler. Det er samtidig i denne periode af livsforløbet, hvor familier dannes og bliver større, samt perioden hvor eventuel uddannelsesdeltagelse finder sted. Denne periode af livsforløbet er en uhyre kompleks periode. Teoretisk tager afhandlingen afsæt i et livsforløbsperspektiv. Livsforløbet bliver betragtet som en social institution, der indfanger de forskellige institutionelle påvirkninger, den enkelte er underlagt. Med dynamiseringen af analysen bliver det også en analyse af ”institutionelle komplementariteter”, dog uden at disse komplementariteter nødvendigvis er positive. Hvorvidt disse additive effekter af den institutionelle konstellation er positive eller negative er et empirisk spørgsmål. Anskuelsen af livsforløbet som social institution får karakter af en normalbiografi, en forventning om hvordan det enkelte livsforløb i praksis bør leves. Dette bliver med andre ord en normativ fordring. Kohlis (2007) formulering af normalbiografien er en tredeling af livsforløbet (uddannelse – arbejdsliv - pension). En tredeling der bliver kritiseret for at være køns- og familieblind, hvorfor linked lives-begrebet bliver introduceret. Begrebet har den teoretiske implikation, at udviklingen i det enkelte livsforløb ikke kun skal anskues som et resultat af persons egne handlinger, men i lige så høj grad er et resultat af samspillet mellem personens egne handlinger og de personlige relationer, som personen indgår i. Afhandlingen stiller sig derved kritisk overfor et metodologisk individualistisk videnskabsteoretisk udgangspunkt. En anden kritik af Kohlis tredeling af livsforløbet er mangel på dynamisk forståelse af uddannelse og især transitioner på arbejdsmarkedet. I forhold til udviklingen af et mere dynamisk perspektiv er TLM (Schmid 1998, 2006, Schmid og Schömann 2004, Räisänen og Schmid 2008) inddraget som operationalisering af transitioner m

  10. Study of silica sorbents by SANS

    International Nuclear Information System (INIS)

    Silica gels under study are materials intended for use as the packing sorbents in liquid chromatography (LC), namely in gel permeation chromatography (GPC). The quality of silica for LC should meet strict physical and chemical parameters. Especially in GPC is very important to know pore size and pore shape because they control the whole process of chromatographic separation. Pore size and thickness of pore wall can be measured by various methods. SANS technique is a nondestructive method providing an average information about a large number of scattering object in our case about objects (pore or wall) in silica and their shape. (author)
