  2. 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

    This profile provides a snapshot of the energy landscape of the Archipelago of San Andres, Providencia, and Santa Catalina (unpopulated), also known as San Andres and Providencia, which is equidistant between Costa Rica and Jamaica and 775 kilometers northwest of Colombia. The archipelago is part of Colombia, though Nicaragua has also laid claim to it.

  5. 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 Netherlands Antilles and other Caribbean islands, with which it also shows a great similarity in the composition of the molluscan fauna.

    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.

    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.

  12. y religion bautista en San Andrés Isla

    2006-01-01

    Full Text Available El presente artículo aborda de manera general los nexos de los pastores y la religión bautista con el movimiento autonomista raizal de la isla de San Andrés. El documento brinda un panorama breve sobre la relación del Estado colombiano con el Archipiélago, la cual incluyó la censura a la lengua inglesa y criolla y a la religión protestante. Así, el artículo establece los orígenes de la participación de las iglesias bautistas en las reivindicaciones a favor de la identidad isleña en la resistencia de los pastores y los fieles protestantes ante las políticas integracionistas nacionales que surgían en el marco de la nación monocultural proclamada en la constitución de 1886. Si bien, a partir de la década de 1960 la resistencia raizal se manifestó en diversos movimientos de carácter secular, a finales de la década de 1990 los pastores retomaron el liderazgo en las demandas por la defensa de la identidad isleña mediante un discurso religioso que se entremezcla con lo político tanto en el espacio de la iglesia como en manifestaciones públicas realizadas en la isla. El artículo propone que el papel de los pastores en el movimiento raizal puede ser comprendido, por una parte, mediante la tradición antiesclavista de la religión bautista a lo largo del Caribe anglófono y, por otra, por la influencia de la iglesia en la vida social isleña como un indicador de respetabilidad, lo cual le permite convocar a la comunidad y ampliar el alcance de las demandas autonomistas del movimiento raizal. Finalmente, el documento plantea que el papel de los pastores como mediadores se enmarca dentro de una tradición más amplia de resolución pacífica del conflicto, expresada en el Caribe mediante la polirritmia, la cual permite la coexistencia de diversas tendencias que no se excluyen mutuamente.

  14. A correlation for miscible flood displacement efficiency in the San Andres with NMR relaxation

    International Nuclear Information System (INIS)

    This paper reports that a set of San Andres crystalline dolomite cores was examined for the relationship between pore attributes discernible from NMR relaxation and miscible flooding displacement efficiency. A strong correlation was observed between the inferred abundance of long relaxation time components and laboratory measured residual oil to a multicontact miscible displacement process. NMR relaxation time distribution proved to be a simple, noninvasive, nondestructive indicator of flow performance in the 12 San Andres dolomite samples examined. Spin-lattice relaxation measurements were conducted on clean, brine saturated core end pieces from plugs taken adjacent to those used for flow displacement studies. Sample data were deconvoluted into a distribution of relaxation times, which is ultimately related to surface-to-volume ratio distribution. The median relaxation time was determined to be the most sensitive statistics to convey flow performance. Residual oil saturation was adequately represented by a power law function of the median relaxation time

    GEOPHYSICAL OBJECTIVES: The goals of work done this quarter were to (1) refine the maps of seismic-derived porosity for the upper Grayburg for reapplication to the production model, (2) determine rock fabric and porosity patterns for the lower Grayburg and the upper San Andres, (3) relate any seismic-derived porosity characteristics, particularly seismic waveform attributes, to the historical production of oil allocated to lower Grayburg and San Andres zones, and (4) to test other geologic attributes for possible inter-relationships. GEOLOGIC OBJECTIVES: Continue the integrated geological/geophysical effort to develop a usable seismic velocity/log porosity transform for each Grayburg producing interval. The lower Grayburg and San Andres core were revisited to glean lithology and porosity information for the seismic inversion model. Update recent production and injection for each well in the study area. Add new production and injection wells to spreadsheet. Continue evaluation of effectiveness of recent completions, plug backs and injector conversions by monitoring oil production and produced water composition. ENGINEERING OBJECTIVES: To build the most accurate reservoir picture by continued integration of all data types available and utilize that model to optimize oil production. Monitoring and testing of new and worked-over wells continues to test the early production models. Methods to improve water quality are being evaluated using normal field management procedures.

  16. 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

    The San Andres Formation is one of the major hydrocarbon-producing units in the Permian Basin, with multiple reservoirs contained within the dolomitized subtidal portions of upward shoaling carbonate shelf cycles. The test well is located in Tedbit (San Andres) Field in northeastern Gaines County, Texas, in an area of scattered San Andres production associated with local structural highs. Selected on the basis of geological and historical data, the Oil and Gas Properties Wood No. 1 well is considered to be typical of a large number of San Andres stripper wells in the Permian Basin. Thus, successful completion of horizontal drain holes in this well would demonstrate a widely applicable enhanced recovery technology. Water-jet horizontal drilling is an emerging technology with the potential to provide significant economic benefits in marginal wells. Forecast benefits include lower recompletion costs and improved hydrocarbon recoveries. The technology utilizes water under high pressure, conveyed through small-diameter coiled tubing, to jet horizontal drain holes into producing formations. Testing of this technology was conducted with inconclusive results. Paraffin sludge and mechanical problems were encountered in the wellbore, initially preventing the water-jet tool from reaching the kick-off point. After correcting these problems and attempting to cut a casing window with the water-jet milling assembly, lateral jetting was attempted without success.

    Cadmium and lead levels were evaluated in water and sediment along the estuarine ecosystem of Tigre River-San Andres Lagoon (Gulf of Mexico) during September to December 2009. Significant highest metal concentration in water (0.45 mg L(-1) Cd and 3.94 mg L(-1) Pb) and sediment (2.83 mg kg(-1) Cd and 6.61 mg kg(-1) Pb) were found at the mouth of the Tigre River, where the fishing town of El Moron is located. Cadmium levels in sediment were above limits associated with adverse biological effects on aquatic fauna, so negative impacts on natural populations of aquatic organisms would be expected to occur. This in turn could affect the fishery resources inhabiting this ecosystem. PMID:22872375

    The spatial distribution of cadmium, lead and zinc concentrations in water, sediment and oysters from San Andres Lagoon was evaluated. Significantly higher cadmium (0.33 mg L(-1)) and lead (0.70 mg L(-1)) concentrations in water were observed in front of the mouth of Tigre river, whereas, zinc concentration (5.0 mg L(-1)) was significantly higher in the south part of the lagoon. Similarly, lead and zinc values in sediment (1.01 and 9.29 ?g g(-1), respectively) and oyster tissue (0.86 and 3.19 ?g g(-1), respectively) were significantly higher in the south part of the lagoon. Levels of cadmium and lead in oyster tissue were positively related to those found in sediment. However, concerning zinc no evident relationship was found. Such differences in regression analyses may be explained by differential bioaccumulation of xenobiotic (cadmium, lead) and essential (zinc) metals. PMID:21336861

Only three brachiopod species have been reported from the Colombian Caribbean Sea so far, namely Argyrotheca barrettiana (Davidson, 1866), Terebratulina latifrons Dall, 1920, and the cosmopolitan Platidia anomioides (Scacchi & Philippi, 1844). In this work, brachiopods collected from deep-water environments (90-250 m) off the San Bernardo Archipelago, collected during the MARCORAL cruise, are examined. The studied material consists of four species, two of which are new records for Colombia: Terebratulina cailleti Crosse, 1865 and Tichosina plicata Cooper, 1977. The genus Tichosina belongs to the family Terebratulidae and comprises twenty extant species occurring across the Caribbean. Based on a revision of published descriptions and illustrations, we synonymize Tichosina bullisi Cooper, 1977 and Tichosina dubia Cooper, 1977 with Tichosina plicata Cooper, 1977. Remarkably, apart from reports from southern Guiana, T. plicata is restricted to the margins of the Caribbean plate.  PMID:25661925

    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.

    An enhanced oil recovery project is being proposed in response to the US Department of Energy`s Near Term Class 2 Oil Program for shallow shelf carbonate reservoirs. Productivity problems associated with a shallow shelf carbonate reservoir will be addressed by integrating high resolution 3-D seismic data, reservoir characterization techniques, and 3-D reservoir simulation. The purpose of the study is to yield results which will preserve access to existing well bores by identifying additional reserves. The general approach will be to shoot a 3-D seismic survey designed specifically for imaging the Grayburg/San Andres interval. The data will then be processed and interpreted using state of the art techniques aimed at identifying porosity, permeability barriers and their zones within the reservoir. A technical team will integrate existing geological data with the geophysical results of the seismic survey for detailed reservoir characterization. These results will be used in a 3-D reservoir simulation model to delineate flow units. A field demonstration of infill drilling and water flood development will follow. The authors expect the results of this study to demonstrate a methodology for reservoir characterization which is feasible for the independent operator. Furthermore, it will provide one of the first public demonstrations of the enhancement of reservoir characterization using high resolution 3-D seismic data. Additionally, it will showcase the improvement of water flood development by using an integrated multi-disciplinary approach, and the addition of otherwise unrecovered reserves by selective infill drilling. This report has four sections: summary of preliminary data; plots and maps; well production data; and well data.

    Seismic objectives addressed during the fourth quarter concerned seismic recognition of Grayburg carbonate porosity and development of maps of the distribution of seismic properties which can be related to reservoir porosity. Synthetic seismograms representing various porosity combinations for the Grayburg A sequence were interpolated in forward models to demonstrate waveform character, and a seismic inversion model was used as the basis for work with seismic-guided attribute maps which have been instrumental in defining porosity within the upper Grayburg. The geologic objectives addressed during the quarter were the integration of the geologic model into the 3D to accurately portray the lithologic markers, the coring and logging of the Witcher {number_sign}12, and working toward the development of a successful completion technique for the lower Grayburg and San Andres. Considerable effort went into developing a usable seismic velocity/log porosity transform. There were a number of engineering objectives this quarter. The development of a successful completion technique for the lower Grayburg and San Andres which would contact the maximum volume of reservoir, minimize potential water production, and be cost effective was a high priority. The Witcher {number_sign}12 was drilled, and Foster-Pegues {number_sign} 4 re-entered and converted to injection this Quarter. The first steps in the quantitative integration of seismic data into the reservoir simulation were taken this quarter. Work on water quality, buildup and fall off tests and the update of production and injection data in the model was ongoing.

    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 buceo es un uso alternativo y no consuntivo de la biodiversidad marina que, debidamente practicado, tiene bajo impacto ambiental, estimula la conservación de los arrecifes y es una opción económica para habitantes de áreas arrecifales o con potencial para el buceo. El archipiélago de San Andrés, Providencia y Santa Catalina, declarado por UNESCO Reserva Mundial de la Biosfera Seafl ower, con 65.000 km2 de Áreas Marinas Protegidas y un extenso complejo arrecifal coralino, tiene condiciones para convertirse en un sitio de buceo de nivel mundial. Sin embargo, es poco conocido. Esta investigación analiza el potencial económico del buceo en esta región y lo compara con el de sitios muy reconocidos como Bonaire y Gran Caimán. Mediante análisis de la disponibilidad a pagar de buzos visitantes, se intenta valorar el buceo y se caracteriza el tipo de buzos que vienen al archipiélago. Se encontró disposición a pagar cifras superiores a las que se paga actualmente en otras partes del Caribe. Con un potencial estimado en $241 millones de dólares de ingresos anuales, el buceo es una interesante alternativa de desarrollo económico sostenible para estas islas que, a pesar de recibir 360.000 turistas al año, aún presentan un 66.9% de pobreza y altos niveles de desempleo.

    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.

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.

    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

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.

Un caso es el de San Andrés Tuxtla, Veracruz, donde el pago no representa una opción económica sostenible a los dueños de predios, por lo que deberá incorporarse también el reconocimiento social. El objetivo del trabajo fue obtener el valor del bosque y paisajes alternativos en la población que recibe sus beneficios en forma de agua. Se realizó trabajo de campo y fueron aplicadas 241 encuestas. Se usó el método de valoración contingente y se incluyeron fotografías de paisajes alternativos a bosque, calificadas en función de su importancia para la economía y la conservación. Se obtuvo la disposición positiva a pagar por mantener el dosel, asociada a ciertas características de la población donde sobresalen ingreso, escolaridad y edad; los datos muestran que el pago deberá considerar valores económicos como costo de oportunidad y reforestación, además del reconocimiento social.

    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. During the first stage of this evolution, a mixed-load system was developed which included low-sinuosity channels and a high participation of floodplain deposits.

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.

El análisis se relacionó con algunas variables físico-químicas y ambientales [...] durante 188 días en San Andrés Isla, entre noviembre 2002 y mayo 2003, en tres estaciones de dos bahías, Hooker y Honda. Se identificaron 34.175 individuos en 130 unidades experimentales, los anélidos mostraron la mayor proporción (77,1%). Se generó un análisis de ordenación y clasificación (dendrograma y un escalamiento multidimensional no métrico-NMDS) para cada uno de los tres taxa estudiados. 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. Bajo condiciones favorables, la abundancia y diversidad de especies tienden a aumentar Abstract in english The early succession of the taxa Annelida, Mollusca and Crustacea on Rhizophora mangle (red mangrove) submerged roots was analyzed using old branches as ground (which were the experimental units) in San Andres Island. The analysis was related to some physico-chemical and environmental variables duri [...] ng 188 days, between November/2002 and May/2003, in Hooker and Honda bays. 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

  7. Regional Oceanography of the Philippine Archipelago

    Directory of Open Access Journals (Sweden)

    Arnold L. Gordon

    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.

For those who lived through the Gargamelle epic, his name is linked with the success of the great bubble chamber that made possible the 1973 discovery of neutral currents. A graduate of Paris's famous Ecole Polytechnique which produced so many great names in particle physics, André Rousset, a native of southern France, joined Louis Leprince-Ringuet's famous laboratory at the Polytechnique in 1954. Among other topics, Rousset played a part in the cosmic ray experiments at the Pic du Midi in the Pyrénées and designed heavy liquid bubble chambers. A Professor at the Ecole des Mines from 1960 onwards, he became deputy director of Louis Leprince-Ringuet's laboratory in 1964.

    The CERN theory community mourns the loss of André Petermann, one of the first members of the Theory Division, who passed away last August in his 89th year. He pioneered, together with his advisor Stueckelberg, the renormalization group, one of the fundamental ideas in quantum field theory that underlies the modern theory of phase transitions as well as asymptotic freedom and the quest for unification of all the particle interactions.   André was among the very first staff members of CERN, which at the beginning was a small group of theorists at the Niels Bohr Institute in Copenhagen, headed by Bohr himself.  When the group moved to Geneva, they first occupied a set of barracks in Cointrin, next to the airport, before moving to the University of Geneva, and then finally settling on the Meyrin site. André was our last direct contact with our nomadic origins. The importance of André’s early work on the renormalization group was recogn...

  2. 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.

    We calculate the singular homology and \\v{C}ech cohomology groups of the Harmonic archipelago. As a corollary, we prove that this space is not homotopy equivalent to the Griffiths space. This is interesting in view of Eda's proof that the first singular homology groups of these spaces are isomorphic.

  5. 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.

    Full Text Available Coral reefs ecosystem is one of favorable sites as habitat of most of marine organismsincluding benthic foraminifera. Foraminiferal assemblages are regularly used as bio-indicators ofenvironmental feasibility for reefs. Hence, the objective of the present study was to recognize theforaminiferal assemblages in the Tambelan Archipelago as a baseline data for monitoring ofenvironmental changes and to plan conservation strategies. The survey was conducted on November2010 at 12 sampling sites around Tambelan Archipelago. A total of 5582 specimens of benthicforaminifera belonging to Order Astrorhizida, Textulariida, Miliolida, and Rotaliida were recorded. Most ofcollected species were recognized as symbiotic-bearing foraminifera; the most common of them whereAmphistegina sp. and Calcarina sp. that counted more than 1000 specimens.

  20. Chemical quality of water and sediment in the bays of Sabana-Camaguey archipelago

    International Nuclear Information System (INIS)

    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 μ?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

  1. San Marino.

    Science.gov (United States)

    1985-02-01

    San Marino, an independent republic located in north central Italy, in 1983 had a population of 22,206 growing at an annual rate of .9%. The literacy rate is 97% and the infant mortality rate is 9.6/1000. The terrain is mountainous and the climate is moderate. According to local tradition, San Marino was founded by a Christian stonecutter in the 4th century A.D. as a refuge against religious persecution. Its recorded history began in the 9th century, and it has survived assaults on its independence by the papacy, the Malatesta lords of Rimini, Cesare Borgia, Napoleon, and Mussolini. An 1862 treaty with the newly formed Kingdom of Italy has been periodically renewed and amended. The present government is an alliance between the socialists and communists. San Marino has had its own statutes and governmental institutions since the 11th century. Legislative authority at present is vested in a 60-member unicameral parliament. Executive authority is exercised by the 11-member Congress of State, the members of which head the various administrative departments of the goverment. The posts are divided among the parties which form the coalition government. Judicial authority is partly exercised by Italian magistrates in civil and criminal cases. San Marino's policies are tied to Italy's and political organizations and labor unions active in Italy are also active in San Marino. Since World War II, there has been intense rivalry between 2 political coalitions, the Popular Alliance composed of the Christian Democratic Party and the Independent Social Democratic Party, and the Liberty Committee, coalition of the Communist Party and the Socialist Party. San Marino's gross domestic product was $137 million and its per capita income was $6290 in 1980. The principal economic activities are farming and livestock raising, along with some light manufacturing. Foreign transactions are dominated by tourism. The government derives most of its revenue from the sale of postage stamps to collectors around the world and from payment of an annual budget subsidy by the Italian government. Despite its close ties with Italy, San Marino has maintained its distinctive status for centuries. PMID:12178101

    Growth estimates of complex orthogonal polynomials with respect to the area measure supported by a disjoint union of planar Jordan domains (called, in short, an archipelago) are obtained by a combination of methods of potential theory and rational approximation theory. The study of the asymptotic behavior of the roots of these polynomials reveals a surprisingly rich geometry, which reflects three characteristics: the relative position of an island in the archipelago, the analytic continuation picture of the Schwarz function of every individual boundary and the singular points of the exterior Green function. By way of explicit example, fine asymptotics are obtained for the lemniscate archipelago $|z^m-1|archipelago, knowing only finitely many of its power moments. This work naturally complem...

    G. F. Andriani

    2005-01-01

    Full Text Available The Tremiti Archipelago (Southern Adriatic Sea, also called Insulae Diomedae from the name of the Greek hero who first landed there, is an area of high landscape and historical value. It is severely affected by significant geomorphologic processes dominated by mass movements along the coast that constitute the most important and unpredictable natural hazard for the population and cultural heritage. Coastal erosion is favoured by the peculiar geological and structural setting, seismic activity, weathering, development of karst processes, and wave action. The present paper reports on descriptive and qualitative evaluation of the factors controlling landslides and coastline changes based on medium-term in situ observation, detailed surface surveys at selected locations since 1995, and historic and bibliographic data. The Tremiti Archipelago is part of an active seismic area characterised by a shear zone separating two segments of the Adriatic microplate that have shown different behaviour and roll back rates in the subduction underneath the Apennines since middle Pleistocene. Although coastal morphology can be basically considered to be the result of wave action, the continual action of subaerial processes contributes effectively to the mechanism of shoreline degradation. Weathering mainly affects the marly calcisiltites and calcilutites of the Cretaccio Fm. and the friable and low cemented calcarenites and biomicrites of the San Nicola Fm. The cliffs are characterised by different types of failure such as lateral spreads, secondary topples, rock falls and slides. At the Isle of San Nicola, landslides are controlled by the contrast in competence, shear strength and stiffness between the Pliocene re-crystallised dolomitic calcarenites and calcisiltites and the Miocene marly calcilutites and calcisiltites. At the Isles of San Domino and Caprara rock falls are attributed to the undercutting of waves at the base of the cliffs.

  19. 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

    Professor André Martin has been awarded the I.Ya.Pomeranchuk Prize 2010, alongside Professor Valentine Zakharov.   André Martin, CERN theorist, pictured at the ceremony held in honour of his 80th birthday (August 2009). Established by the Institute of Theoretical and Experimental Physics (ITEP) in memory of an outstanding scientist Isaak Yakovlevich Pomeranchuk, the prize is awarded for the study of analytic properties of the scattering amplitude; which lead to the Froissart—Martin bound on the cross section growth with energy. The prize comes as a great honor for Martin, who was in fact a good friend of Mr. Pomeranchuk, "I am surprised and delighted to learn that I will be receiving the 2010 Pomeranchuk Prize. I was an admirer of Pomeranchuk and we shared a great friendship. I met with him for the last time in Erevan (Armenia) in 1965. As a good-bye, he told me, 'Analyticity exists'.

    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.

    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

    2015-04-01

    Over one thousand islands with rocky shores are distributed and concentrated along the southwestern coast of the Korean Peninsula. Various tidal flats formed along the rocky coasts of the archipelago have been developed due to the relative decrease in accommodation space by slow sea-level rise on broad marginal epicontinental seas during the Holocene. Sedimentation and evolution on these archipelago tidal flats (ATF) show quite distinctive and various tidal flat patterns, depending upon the location and direction of rocky shores which have been constantly influenced by monsoon winds reversely changing with season. Generally ATF is characterized by surrounding wave-dominated sand flats along the outside of the archipelago and by broad tide-dominated mud flats in its central part with spring tidal range reaching up to 6 meters. The open-coast outside sand flats and inner mud flats are completely different in terms of sedimentation and the evolution of sedimentary sequences. The former has been deposited by the transgressive sedimentation with strongly destructive and weakly constructive wave/tide processes, forming relative thin and younger (ca. 3,000 yrs BP) remnant storm-dominated sandflat units. The latter has been deposited by continuous transgressive settling with constructive tidal processes during Holocene, forming relative thick and older (from ca. 7,000 yrs BP) mud-flat units. Geomorphological features and the geological evolution of the ATF (Shinan archipelago and Yoobudo islands in Seocheon) display a quite distinctive pattern of ongoing geological processes from the Wadden Sea tidal flats which was already inscribed as World Natural Heritage. Therefore, the Outstanding Universal Values of the Korean ITF for criteria (vii) and (viii) should provide a strong support for the additional World Natural Heritage Site.

    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.

    2014-01-01

    Outside the professional circles of topography and applied mathematics, the life and work of André-Louis Cholesky (1875–1918) are still relatively unknown to the scientific community. This new book appreciably widens the exposure of his remarkable personal achievements in topography and mathematics to a much larger international audience.   Cholesky is also interesting to historians because he is a perfect representative of the "scientists engineers" that, since the early 19th century, had issued from the French scientific high schools. Because they had received a high level of mathematical education, they were able to innovate in their practice of engineering. In the case of Cholesky, this resulted in original contributions in artillery, topography, numerical analysis and graphical calculation. In addition, the book places his education and works within the history of several European countries through the 17th to 19th centuries.   The book begins with Cholesky's biography, followed by his family’s hi...

Det epidemiologiskeperspektivet på vold har blitt forsterket og et mer etiologisk og preventivt syn på volden er mere merkbarinnenfor sosialmedisinsk forskning. Alkoholen er en etiologisk faktor som har vist seg å være forbundet med voldi de aller fleste samfunn. I denne artikkelen beskrives de viktigste epidemiologiske metodene og funnene i studietav alkoholens sammenheng med vold. Denne sammenhengen har vist seg ikke å være direkte, men er avhengig aven rekke andre faktorer, og noen forskjellige typer av kausal avhengighet beskrives i artikkelen. Den epidemiologiskeforskningen om andre rusmidlers sammenheng med vold er betydelig mindre omfattende enn den er foralkohol. Det er også åpenbart at andre rusmidler ikke er like sterkt sammenknyttet med vold som alkoholen.Pernanen K. Alcohol, other drugs, and violence in an epidemiological perspective.Nor J Epidemiol ENGLISH SUMMARYThe public health approach to violence has become increasingly accepted during the last couple of decades. 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.

    2007-01-01

    This paper provides an analysis of the structure of the health care delivery system, emphasizing physician group practices. The authors argue for comprehensive integrated delivery systems (IDSs). The jumping-off point for their analysis is the recently published Redefining Health Care: Creating Value-Based Competition on Results, by Michael Porter and Elizabeth Teisberg. The authors focus on the book's core idea that competitors should be freestanding integrated practice units (or "islands in archipelagos") versus IDSs (or "medical homes").

    2011-01-01

    There are two main approaches to the problem of realizing a $\\Pi$-algebra (a graded group $\\Lambda$ equipped with an action of the primary homotopy operations) as the homotopy groups of a space $X$. Both involve trying to realize an algebraic free simplicial resolution $G_\\bullet$ of $\\Lambda$ by a simplicial space $W_\\bullet$ and proceed by induction on the simplicial dimension. The first provides a sequence of Andr\\'{e}-Quillen cohomology classes in $H_{AQ}^{n+2}(\\Lambda;\\Omega^{n}\\Lambda)$ for $n \\geq 1$ as obstructions to the existence of successive Postnikov sections for $W_\\bullet$ by work of Dwyer, Kan and Stover. The second gives a sequence of geometrically defined higher homotopy operations as the obstructions by earlier work of Blanc; these were identified with the obstruction theory of Dwyer, Kan and Smith in earlier work of the current authors. There are also (algebraic and geometric) obstructions for distinguishing between different realizations of $\\Lambda$. In this paper we 1) provide an explic...

  3. The Idea of the Archipelago: Contemplating Island Relations

    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.

    Past works on scale insects (Hemiptera: Coccoidea) from the Maltese Archipelago are reviewed. Based on the literature and contemporary collections, a total of 93 species of scale insects belonging to 12 scale insect families are here reported (Aclerdidae 1 species; Asterolecaniidae 4; Coccidae 17; Diaspididae 46; Eriococcidae 5; Kermesidae 1; Margarodidae 1; Micrococcidae 1; Monophlebidae 2; Pseudoccocidae 11; Putoidae 2 and Rhizoecidae 2). Of these, 17 species represent new distribution records. Ten species are excluded from the scale insect fauna of the Maltese Islands. Of the 93 species present, only 29 (31.18%) are probably indigenous and the rest (68.82%) represent established introductions from elsewhere. More than 65% of the indigenous species are typical Mediterranean in distribution, with a few species having a mainly European chorotype. A quarter of the established aliens originate from Eurasia, followed by an East Asian/ Oriental component (20.31%); European (14.06%); Neotropical (14.06%); cryptogenic (14.06%); African (7.81%) and Australasian (4.70%). Movement of live fruit trees and ornamental plants into the Maltese Archipelago from nearby countries is probably the main route for entry of alien scale insects into the country. Some possible future introductions are discussed. PMID:25283672

    Full Text Available The oceans cover 70 % of the Earth´s surface and harbor most of the planet´s biodiversity. However the microbiological component of this diversity remains relatively unexplored. Marine actinomycetes, are a robust resource of chemically prolific novelty. Producing structurally unique biological active secondary metabolites, generating a valuable source for innovative biotechnology and drug discovery[1,2]. As a consequence, the ecological role of actinomycetes and their marine ecosystems may no longer be neglected. It is crucial to move our research efforts into ocean regions for which we know little or nothing about the indigenous microbial diversity. The Portuguese Archipelago, Madeira is located in the Macaronesian Atlantic region, emerging from the African tectonic plate, found in the extreme south of the Tore-Madeira ridge, has a unique biogeography and biodiversity. These distinctive characteristics combined with the fact that Madeira have never been explored, as far as indigenous marine actinomycetes are concerned, makes it from the scientific point of view, the perfect target for our studies. From 662 marine sediment samples collected along Madeira Archipelago (Figure 1 during June of 2012, covering depths from 10-1310 m, a total of 421 actinomycete strains were isolated. In a previous study, an assemblage of 82 strains was selected for taxonomic identification, having into account representative morphological diversity characteristics of the actinomycetes, isolated from Madeira Archipelago. Based on 16S rRNA gene sequencing, it was observed that the genera Streptomyces, Micromonospora and Salinispora were predominant, 81% [3]. Additionally, in a recent study, our team selected 168 strains with Salinispora look-alike morphological features. From these 28 strains were identified as belonging to the seawater-obligate marine actinomycete genus Salinispora. Representing the first report of Salinispora spp. in the Macaronesian Atlantic Ocean region and suggesting a more globally distribution of this genus than previously supposed (unplublished results. In this study further 82 strains from Madeira Archipelago (out of 421 were selected for taxonomic identification, taking into account small groups of strains (1-4 evidencing very diverse morphological appearances, as exemplified in Figure 2. Using the same experimental microbiology identification tools, 8 genera were identified. However it was perceived that, the genera Streptomyces, Nocardiopsis and Actinomycetospora were predominant (93%, Figure 3. The phylogenetic trees built for the 82 taxonomically identified strains performed in this study are presented in Figures 4, 5 and 6. To date, having into account the present work and previous studies, our research group have identified from the actinomycetes isolated from Madeira´s ocean sediments, genera Streptomyces, Micromonospora, Salinispora, Nocardiopsis, Verrucosispora, Kocuria, Nonomuraea, Nocardia, Brevibacterium, Mycobacterium, Marinobacter, Actinomadura, Micrococcus, Actinomycetospora, Pseudonocardia, Gordonia and Millisia. From which genera Streptomyces, Micromonospora, Salinispora evidence a major representation. Crude extracts were obtained from all 421 strains and tested for their ability to produce natural products with bioactive properties: (i antimicrobial activity against methicillin-resistant Staphylococcus aureus (MRSA, vancomycin-resistant Enterococcus faecalis (VRE and Candida albicans strains; and (ii cytotoxic activity against the HCT-116 cell line. A screening positive rate of 2.4% for antimicrobial MRSA and VRE assays and 3.2% for cytotoxic HCT-116 assay was obtained (submitted manuscripts. These studies demonstrate that the Macaronesian Atlantic Ocean region is a rich source of marine actinomycete biodiversity with potential industrial applications. Figure 1.

    2015-01-01

    Abstract The Canadian Arctic Archipelago is a vast region of approximately 1,420,000 km2, with a flora characterized by low species diversity, low endemicity, and little influence by alien species. New records of vascular plant species are documented here based on recent fieldwork on Victoria and Baffin Islands; additional records based on recent literature sources are mentioned. This paper serves as an update to the 2007 publication Flora of the Canadian Arctic Archipelago, and brings the total number of vascular plants for the region to 375 species and infraspecific taxa, an increase of 7.7%. Three families (Amaranthaceae, Juncaginaceae, Pteridaceae) and seven genera (Cherleria L., Cryptogramma R. Br., Platanthera Rich., Sabulina Rchb., Suaeda Forssk. ex J.F. Gmel., Triglochin L., Utricularia L.) are added to the flora, and one genus is deleted (Minuartia L.). Five species are first records for Nunavut (Arenaria longipedunculata Hultén, Cryptogramma stelleri (S.G. Gmel.)

    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.

    Full Text Available I artikkelen stilles følgende forskningsspørsmål: Hvordan deltar små barn med cochleaimplantat i interaksjoner med andre barn i barnehagen og hvordan skaper cochleaimplantat mulighetsbetingelser for deltakelse? Tre barnehager inngår i studien og barna som medvirker er i alderen 1 ½ - 3 år. Interaksjoner mellom barna er videofilmet og analysert. Barnas interaksjoner ser ut til å handle om å finne en rytme, i studien identifisert som henholdsvis takt og utakt, som svarer til deltakernes interesser og bruk av medierende redskaper. Et sentralt funn er at barn med cochleaimplantat er aktive deltakere i begge former for interaksjoner på tilsvarende måte som andre barn. Studien dokumenterer hvor sentralt cochleaimplantatet er som vilkår for barnas deltakelse, og hvor sårbar deres deltakelse i interaksjoner med andre barn kan bli dersom teknologien ikke fungerer som den skal. Studien viser også at kompetansen til de voksne som jobber i barnehagen har stor betydning for barn med cochleaimplantats vilkår for deltakelse.

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

    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.

His infamous photograph Piss Christ (1987 is the oft-cited example at the center of the National Endowment for the Arts controversies during the Culture Wars of the 1980s and 1990s. I return to Piss Christ as a way to expand the interpretative scope of Serrano’s early photographs, which I call “taboo icons” because of their ambiguity and ability to crisscross symbolic boundaries in the unstable space between sacred and profane, thus making his images both powerful and potentially dangerous. Building upon previous scholarship that draws connections between modern and early modern aesthetic practices, I look to the material practices of Christianity in medieval Europe characterized by a sophisticated visual culture that mixed both the physical and the spiritual. The intensifying rejection and reverence of matter resulted in divergent responses, yet the contradictory nature of matter remained central to the ideological beliefs of Christianity where the doctrines of Creation, Incarnation, and Resurrection are at its core. Serrano’s visceral photographs are emphatically material and can productively be read vis-à-vis medieval visual culture. In doing so, this reading changes the narrow perception of Serrano’s early photographs and provides an alternative understanding of his artistic project that reinserts religion into contemporary American art discourse.

    Full Text Available This article outlines the development of Vietnam’s Con Dao archipelago (and Con Son island in particular as tourism destinations since the formal reunification of Vietnam in 1975. In particular it examines the nature of the area’s two main tourism attractions, Con Son’s prison sites and memorials and the archipelago’s natural environment, and how these have been marketed to and experienced by national and international tourists. This discussion also involves considerations of the concept of thanatourism and how the latter might be understood to operate in a Vietnamese context. The final sections of the article consider development plans and options for the archipelago; how these can be understood within national political contexts; and what problems there might be with their implementation.

    Full Text Available En Colombia, la apicultura es una actividad económica en consolidación, que representa un potencial de riqueza por los múltiples beneficios que se pueden obtener a través de la explotación artesanal o industrial. En el sector agropecuario es una de las 37 cadenas productivas registradas ante el Mini [...] sterio de Agricultura y Desarrollo Rural; es objeto de priorización en procesos de investigación, desarrollo e innovación (I+D+i), en aras de incrementar su productividad y competitividad, involucrando la sostenibilidad de la población rural y el componente industrial. El Archipiélago de San Andrés, Providencia y Santa Catalina es objeto de iniciativas de desarrollo rural, impulso empresarial y fortalecimiento, pues ante la coyuntura socioeconómica por la disminución del territorio marítimo, busca diversificar las actividades económicas de la población raizal. Con la metodología de alianzas productivas y los itinerarios de ruta como herramienta de gestión e integración se diseñó, desde el enfoque tecnológico, la estructura de la minicadena productiva de eslabones y segmentos; las directrices fueron los procesos productivos de tipo orgánico, selección de tecnologías, proveedores y mecanismos de certificación al producto y capacitación al recurso humano requerido, mediante un proceso analítico jerárquico utilizando el software Expert Choice. Se estructuraron lineamientos desde la base de política pública y sectorial, consignada en la agenda única nacional de I+D+i de la cadena y lineamientos establecidos (plan de desarrollo del departamento, plan de ciencia y tecnología, CONPES y plan de ordenamiento territorial). La minicadena y el paquete tecnológico de apicultura orgánica son un insumo de competitividad para el archipiélago. Abstract in english In Colombia, beekeeping is an economic activity under consolidation, which represents a potential wealth for the many benefits that can be obtained through craft or industrial exploitation. It is one of the 37 productive agricultural-chains formed and registered through the Ministry of Agriculture a [...] nd Rural Development, and is subject to research, development and innovation (R+D+i) priority processes to increase productivity and competitiveness, involving both the sustainability of the rural population and the industrial component. The Archipelago of San Andres, Providencia and Santa Catalina is the subject of rural development initiatives, business and strategic planning because of the socioeconomic situation due to the reduction in maritime territory, seeks to diversify the economic activities of the native population. Within the framework of the productive chains and the strategy of the roadmaps itineraries as a management and integration tool, the mini productive chain was design, contemplating organic production process and rules, selection of technologies, suppliers and product certification mechanisms to the human resource and training required, through an analytic hierarchy process using Expert Choice software. Finally, a work plan was defined as the sole national research agenda R+D+i (Research + Development + innovation) for the national productive chain and the guidelines established in the department's development plan, the science and technology plan, the CONPES and the Territorial Order Plan.

  8. Structural Analysis of the Louisiade Archipelago, Southeastern Papua New Guinea

    2009-12-01

    The Louisiade Archipelago lies on the southern rifted margin of the Woodlark Basin in SE Papua New Guinea. Field work in the Calvados Chain and on Sudest and Rossel Islands was undertaken to investigate possible correlations with high and ultrahigh-pressure metamorphic rocks exposed in the D’Entrecasteaux Islands exhumed ahead of the westward-propagating seafloor spreading rift tip. Data from the Louisiade Archipelago are critical for evaluating the transition from subduction to rifting in the region and thus for testing models for the exhumation of high-ultrahigh-pressure rocks in southeastern Papua New Guinea. The Calvados Schist, most commonly represented by fine-grained phyllite recording recrystallization at lower greenschist-facies, is the predominant rock type in the Louisiade Archipelago. Protoliths include siltstone, shale, sandstone, pebbly sandstone, and minor conglomerate. Minor metamorphosed mafic intrusives are also present. Primary bedding is apparent locally and up to three, but more typically two, generations of foliations are discernable. S1 foliations locally correspond to compositional banding and closely parallel S0. S1-S3 foliations principally dip shallowly-moderately to the NE. Regionally, poles to foliation define a girdle about subhorizontally ESE plunging folds. S2 foliations, commonly the dominant fabric, were observed to be axial planar at several localities. Quartz veins are prevalent and locally concordant with S1 foliations and folded during S2 foliation development. S1-S2 foliations are locally cross-cut by quartz veins/tension gashes of which a subset fits with WNW-ESE extension. Both mineral and intersection lineations plunge shallowly ESE, parallel to fold hinges. The initial analysis suggests subsequent foliation development during progressive deformation. Meta-mafic lithologies were observed on Sudest and Rossel Islands. On Rossel Island, serpentinized ultramafic rocks structurally above and in fault contact with the Calvados Schist may constitute a klippe of the Papuan Ultramafic Belt. Low angle faults with both top-to-the-NE and top-to-the-SW kinematic indicators were observed at the base of the ultramafic unit on western Rossel Island, possibly reflecting that the fault was reactivated (e.g., thrust fault reactivated as a normal fault). Gabbro and unmetamorphosed sedimentary rocks intruded by mafic dikes observed on western Rossel Island may also constitute upper plate lithologies. Calcite veins crosscutting mafic and ultramafic lithologies in the upper plate generally fit with NE-SW extension. Preliminary analyses of fault-slip data reveal the presence of a population of faults that crosscut both the ultramafic rocks and Calvados Schist (inferred upper and lower plates). The faults are dominated by NE-striking sinistral faults associated with N-S compression and E-W extension. Fault slip analyses from the low angle normal faults at the base of the ultramafic unit are consistent with subvertical WSW compression and subhorizontal ENE extension. The results of this work will be evaluated in the context of the active tectonic framework and the along-strike record of evolution of the Woodlark Rift.

    A project to recover economic amounts of oil from a very mature oil field is being conducted by Laguna Petroleum Corporation of Midland, Texas, with partial funding from a U. S. Department of Energy grant to study shallow carbonate rock reservoirs. The objectives of the project are to use modern engineering methods to optimize oil field management and to use geological and geophysical data to recover untapped potential within the petroleum reservoirs. The integration of data and techniques from these disciplines has yielded results greater than those achievable without their cooperation. The cost of successfully accomplishing these goals is to be low enough for even small independent operators to afford. This article is a report describing accomplishments for the fiscal year 1997-1998.

  12. 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 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

  14. SANS studies of polymers

    International Nuclear Information System (INIS)

    Before small-angle neutron scattering (SANS), chain conformation studies were limited to light and small angle x-ray scattering techniques, usually in dilute solution. SANS from blends of normal and labeled molecules could give direct information on chain conformation in bulk polymers. Water-soluble polymers may be examined in H2O/D2O mixtures using contrast variation methods to provide further information on polymer structure. This paper reviews some of the information provided by this technique using examples of experiments performed at the National Center for Small-Angle Scattering Research (NCSASR)

    The archipelago Franz-Josef Land is situated in the Arctic Ocean (80°40' N, 54°50'E). It is one of the important areas for arctic research due to organization of Russian Arctic National Park there. Therefore, an interest to the environmental history of this territory grows up and any new data might have a high value. However, geographical remoteness of the archipelago is the reason why there are not much work has been done up to date. .A focus of our researches is vegetation and climate reconstruction during the Late Holocene history according pollen data. In frame of studying of the Franz Josef Land during complex expedition of Russian Arctic National Park on the islands geomorphological and botanical researches was occurred. Nowadays the typical island of archipelago presents the ice cap and glacier-free marine terraces of 35 m high at maximum, where solifluction and permafrost are developed. The archipelago has a maritime Arctic climate. Vegetation of archipelago Franz-Josef Land presents the northern type of Polar Desert. It includes 57 species of vascular plants (Poaceae, Juncaceae, Caryophyllaceae, Brassicaceae, Saxifragaceae etc). We studied the peat core from the southern part of Majbel Island, in the archipelago Franz Josef Land. More than a half of the island is covered by glacier. The core was sampled at the inner margin of ice-free high marine terrace, near the southern slope of bedrock hill. We received preliminary pollen data and radiocarbon data 3010±80 C14 y.a. at the bottom. The pollen concentration is low, but we manage to make some reconstructions of vegetation and climate. For correct interpretation of our results, we used surface samples from different islands of archipelago (Jackson, Hooker, Greely, Alexsandra land, Yeva-Liv, Appolonov, Georg land, Kane, Bell). Subrecent spectra include species presented in flora of region, but also those which are not founded at this region in this time.

  18. Promotional archipelagoes of change. Spatial analysis of Dinosauro

    International Nuclear Information System (INIS)

    During the last decades, the post industrial Latin American cities have become important economic centers in the world. Their integration into the world economy helped those cities become in the favorite places for the linking functions and activities to the world nets of commerce, productions culture, etc. These urban centers which are expanding gradually into segmented developing areas have caused an apparent space duality between the private and public activities as it can be seen though the differential access to goods and services by the society. At present, there has been an increase in cultural activities which form change promoting archipelagoes subject to several dimensions of analysis. The inequity in the distribution of economic and educational resources causes unequal ways of access to consumption of these areas of cultural production, and of goods and services, what gives place to situations of social exclusion and inclusion. To understand this fact related to money behavior, we have selected an area situated in the northwest of Cordoba capital city, in Argentina, which is a shopping mall called Dinosaurio Group. In this essay we present an exploration into the conflicts caused to the cities through the expansion of the segmented urban centers, promoters of change, and its relationship with the public and private space.

    2014-12-01

    Following relocation of events with the double-difference location algorithm (HypoDD), we apply tomographic methods to extract 3D attenuation models illuminating the plumbing system of the Sierra Negra Caldera of the Galapagos Archipelago. The dataset consists of 1737 events recorded from July 2009 to June 2011 on the 17-station SIGNET broadband seismic array. We use t* spectral decay methods for both P- and S- phases with the clustered locations to highlight locations where significant variations in Q suggest the presence of magma melt. While the presence of a magma sill, at least 2 km depth, is indicated by InSAR and GPS studies, the delineated magma body has not been explored in detail. The lower bound of the proposed magma accumulation is still under question and thus forms the primary target of this research. Melt replenishment and degassing of the magma sill is believed to cause inflation and/or deflation of the caldera floor. Imaging the extent of the magma sill will provide insight into the feeder system and deformation process of the Sierra Negra caldera. Detailed relocation, Qp and Qs inversion, as well as estimates of the scattering attenuation using coda-normalization technique will be presented. The close relationship between seismic attenuation and the thermal state of the magmatic system suggests we can distinguish melt and/or fluid regions within the Sierra Negra plumbing system.

  2. Subtidal reef fish and macrobenthic community structure at the temperate Juan Fernández Archipelago, Chile

    2014-10-01

    Full Text Available The Juan Fernández Archipelago (33°37'S, 78°51'W, an isolated group of islands 650 km west of continental Chile, has a high degree of endemism in its marine biota. Despite numerous scientific expeditions to these islands that have identified this high endemism, few studies have attempted to identify patterns of community structure in subtidal habitats. 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.

    2015-04-01

    Antarctic Peninsula is a part of Antarctica which is characterized by increased soil diversity, caused by specific of parent materials and diversity of non-vascular and vascular plants. Soils of Galindez Island have been investigated during the 18-th Ukranian Antarctic Expedition 2013/14. This Island situated in Argentine archipelago (coastal part of Antarctic Peninsula). Soils of Galindez Island presented by following types: Leptosols, Lithosols, Histic Lithosols and Leptosols and some Gleyic soils, located in lowlands and coastal parts. An average solum profile thickness is 3-19 cm which result from the small depth of debris's, underplayed by massive crystallic rocks. The permafrost layer is located within the massive rock, but not in coarse friable parent material. The soils with bird influence are widely spread both in coastal and central part of Island. In the coastal parts we can find typical Ornithosols in the penguin rockeries areas. The main aim of our investigation was characterization of soils formed under vegetation, exactly under Deschampsia antarctica Desv. localities. Argentine Islands is the central part of D. antarctica spreading area in region of Antarctic peninsula. Probably, these islands colonized by hairgrass mainly due to ornitogenic activity. So, coastal population appearance related with Larus dominicanus nest areas and feeding activity. Thus, we found typical post ornithogenic soils here. This kind of soils we also observed in population of hairgrass of Galindez mainland where it was connected with the other Antarctic bird - Catharacta maccormicki activity. Thus, the soil diversity and soil geochemistry of the Galindez Island are closely related to the activity of birds. The spatial pattern of soils, their chemistry and organic matter quality is discussed in relation with distribution of bird nesting and feeding activity.

  6. Barium and Carbon fluxes in the Canadian Arctic Archipelago

    The seasonal and spatial variability of dissolved Barium (Ba) in the Amundsen Gulf, southeastern Beaufort Sea, was monitored over a full year from September 2007 to September 2008. Barium displays a nutrient-type behavior with the highest concentrations observed at river mouths. The water column maximum is located at the base of the surface layer with lower concentrations above and below. The lowest concentrations are found in water masses of Atlantic origin, and Ba concentrations decrease eastward through the Canadian Arctic Archipelago. A three end-member mixing model comprising fresh water from sea-ice melt and rivers, as well as upper halocline water, was used to establish their relative contributions to the surface waters of the Amundsen Gulf. Based on water column and riverine Ba contributions, we assess the Ba depletion by particle sinking and subsequently estimate the carbon export production. In the upper 50 m of the water column of Amundsen Gulf, riverine Ba accounts for up to 15% of the dissolved Ba inventory, whereas up to 20% of the dissolved Ba inventory is depleted by barite (BaSO4) formation and export. Since riverine inputs and Ba export occur concurrently, the seasonal variability of dissolved Ba is moderate. Assuming a fixed organic carbon to barite flux ratio, carbon export out of the surface layer is estimated at 2 mol C m-2 yr-1. Finally, we propose a climatological carbon budget for the Amundsen Gulf based on recent literature data and our findings, the latter bridging the surface and subsurface water carbon cycles. This work is a contribution to the Canadian IPY programs CFL and GEOTRACES, to ArcticNet as well as to the IGBP/IHDP core project LOICZ.

    Full Text Available Decapod community inhabiting the rocky littoral of eight bays from Socorro island, Revillagigedo Archipelago, was studied during March 1992. Samples were collected from one-square meter plots placed following transects drawn perpendicularly to the shoreline along the intertidal zone. Species richness and abundance were determined in each bay, as well as the similarity between bays using Morisita’s index. Organisms collected belong to six families, 20 genera and 26 species of the Brachyura and Anomura infraorders. Xanthidae was the family with the highest number of species, and the highest species richness was recorded at the V. Lozano bay. Pachygrapsus transversus, Xanthodius cooksoni and Calcinus explorator were the most abundant species in nearly all localities. Dendrogram obtained define two groups of bays at a similarity level above 0.67, given the similarity in the crab’s species richness and their abundance between bays in the island.Se estudió la comunidad de cangrejos del litoral rocoso de ocho bahías de la Isla Socorro, Archipiélago Revillagigedo en marzo de 1992. Las muestras fueron colectadas en cuadrantes de un m² a lo largo de transectos perpendiculares a la costa en la zona intermareal. Se determinó la riqueza específica, la abundancia por especie para cada bahía, así como la similitud entre bahías mediante el índice de Morisita. Los organismos colectados pertenecen a seis familias, 20 géneros y 26 especies de los infraordenes Brachyura y Anomura. La familia con el mayor número de especies fue Xanthidae y la mayor riqueza específica se registró en la bahía V. Lozano. Pachygrapsus transversus, Xanthodius cooksoni y Calcinus explorator fueron las más abundantes en casi todas las localidades. En el dendrograma se definen dos agrupaciones con nivel de similitud superior a 0.67, dada la semejanza en la riqueza específica de cangrejos y las abundancias entre las bahías.

Se utilizó análisis etnográfico, sociológico y valoración contingente en una muestra de 171 consumidores en Coatepec y 228 en San Andrés, así como 85 productores, 45 de ellos de Coatepec. Los resultados mostraron que la población privilegia los valores económicos de los paisajes que componen las zonas de pago. Existe un fuerte potencial para incorporar el reconocimiento social en la generación de servicios ambientales, lo que podría incrementar el pago a los productores para observar un impacto socioeconómico real del PSAH. Se identificaron diferencias entre los actores respecto a valor de un m³ de agua, tanto dentro como entre zonas, ya que los valores fiscales de referencia y del productor fueron mayores en Coatepec. Los programas de conservación y las políticas públicas inherentes deberán considerar la voluntad de todos los actores sociales para obtener un impacto visible. Abstract in english Some areas in San Andres Tuxtla and Coatepec, Veracruz State, Mexico, that have received payment for hydrological environmental services (PHES) since 2004 were studied. The objective was to analyze PES's socioeconomic impact through its effects on the local market for water, to grasp social percepti [...] ons about water value, and to assess the possible impact of implementing PES. Ethnographic, sociological, and contingent valuation analysis were used in a sample of 171 consumers from Coatepec, and 228 from San Andres, as well as a total number of 85 producers, 45 of whom come from Coatepec. Results showed that the public admits an economic value for landscapes where PES are paid. There is a strong potential to incorporate social recognition in the production of environmental services. Differences were found in the value of a cubic meter of water among stakeholders within and between areas, since producer and government stated values were higher in Coatepec. Future environmental conservation programs and public policies should consider the will of all stakeholders to be able to produce visible outcomes.

  12. The island as container: islands, archipelagos and player movement in video games

    Full Text Available The use of islands and archipelagos as settings in video games has proven enduring and popular: these locations are usually shown to be dangerous places where travel can be difficult. The use of island and archipelago settings in this medium developed along with conventions about water in general being an obstacle to traverse, meaning that player characters that experience islands and archipelagoes are forced to discover ways to travel around, over, and away from them. Islands remain popular settings because they work well with players’ preconceptions about these spaces, with people’s understandings of natural boundaries that make travel difficult, and with game designers’ intent to control player character movement throughout a world that is necessarily constrained by the reach of technology.

The structure faults yield 49% of the incidents; shortcomings in personnel training - 16%; lack of understanding -19%; man-machine interaction - 8%; others -8%. Measures to minimize the outages include upgrading the most dangerous plants, review of operational instructions, additional training of personnel and consideration of incidents reasons

  14. Intensification of the Atlantic Deep Circulation by the Canadian Archipelago Throughflow

    2004-12-01

    In the northern high latitudes, where deep water formation occurs, horizontal freshwater transport in the form of seawater and sea ice is a major component of the freshwater budget. The horizontal freshwater transport controls the surface salinity in this region, and thus has a significant impact on the deep water formation process and the resultant Atlantic deep circulation. In this study, we focus on the freshwater transport through the Canadian Archipelago, and investigate how the intensity of the Atlantic deep circulation depend on opening and closing of the Canadian Archipelago. An ice-ocean coupled model is used; it consists of the oceanic component COCO3 (CCSR Ocean Component Model version 3) and the sea ice component including dynamics and thermodynamics. The horizontal resolution is 1 degree. Restoring surface salinity to observed data is not employed. When the Canadian Archipelago is opened, the Atlantic deep circulation strengthens by 21 %. The deep water formation in the northern North Atlantic is responsible for the enhancement. The flow of a low salinity water through the Canadian Archipelago does not directly affect the deep water formation in the northern North Atlantic, since it flows only in the western part of the Labrador Sea. The confinement of the flow in the western Labrador Sea is caused by the reproduction of the cyclonic circulation there. Instead, the surface salinity in the deep water formation region is affected by the East Greenland Current, which flows from the Fram Strait along the east coast of Greenland and increases its salinity by opening the Canadian Archipelago. Consequently, the deep water formation is activated there and the Atlantic deep circulation strengthens. Thus, it is suggested that the Canadian Archipelago throughflow does not directly suppress the deep water formation in the northern North Atlantic, but indirectly activate it by the increase in salinity of the East Greenland Current.

    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.

El análisis de la estructura del bosque y de imágenes clasificadas indicó que estos sitios son espacialmente dinámicos y parecen estar regenerándose. La estructura del bosque indica que el crecimiento en los sitios ha estado limitado por las actividades humanas y posiblemente por otros factores.

Éste sitio no parece mostrar la misma extensión de rebrote espacial de los otros dos sitios entre 1986-2000 y es relativamente estático. El establecimiento de parcelas permanentes y el monitoreo serán útiles en la implementación del plan de manejo, ya que los manglares del LPA tienen una variedad estructural y podrían estar sujetos a un mayor desarrollo costero.

The prevalence of such drugs among drivers involved in accidents depends on theincrease of the accident risk due to the drug and on the prevalence of the drugs among drivers on the road. Inthis study we have examined blood samples from 394 drivers involved in road traffic accidents during theperiod August–December 1993, to determine the prevalence of alcohol and drugs among drivers involved inaccidents. Most of the drivers enrolled in the study were suspected by the police of driving under the influenceof alcohol or drugs. The data are, however, probably somewhat biased, because drivers influenced by alcoholor drugs will, if possible, avoid contact with the police. Furthermore, the police's ability to detect driversinfluenced by drugs is limited. Accordingly, the proportion of influenced drivers and especially drivers influencedby drugs could be too low compared with the proportion among all drivers involved in traffic accidents.In about 2/3 of the blood samples examined, alcohol was found either alone or together with other drugs,and in 1/4 of the cases drugs were found either alone or together with alcohol. The most prevalent drugs werebenzodiazepines (13.7%, cannabis (7.5%, opiates (4.3% and amphetamine (4.1%. In about 3/4 of the drugpositive cases the drug concentration was so high that it was considered likely or very likely that the driverwas influenced by the drug(s. The bias due to the police's inability to detect all drivers influenced by drugs50A. BJØRNEBOE OG MEDARBEIDEREwas estimated. After correction for this bias it was estimated that at least 2.7% of drivers involved in injuryaccidents will have significant concentrations of drugs in the blood and at least 4.4% will have significantblood alcohol concentrations.Based on various sources of drug use in Norway we arrived at rough estimates of increase in risk of beinginvolved in road traffic accidents after different drug intakes.

  19. Tsunami hazard assessment for the Azores archipelago: a historical review

    Science.gov (United States)

    Cabral, Nuno; Ferreira, Teresa; Queiroz, Maria Gabriela

    2010-05-01

    The Azores islands due to its complex geographical and geodynamic setting are exposed to tsunamigenic events associated to different triggering mechanisms, local or distant. Since the settlement of the Azores, in the fifteenth century, there are several documents that relate coastal areas flooding episodes with unusually high waves which caused death and destruction. This work had as main objective the characterization of the different events that can be associated with tsunamigenic phenomena, registered in the archipelago. With this aim, it was collected diverse documentation like chronics, manuscripts, newspaper articles and magazines, scientific publications, and international databases available online. From all the studied tsunami events it was identified the occurrence of some teletsunamis, among which the most relevant was triggered by the 1st November 1755 Lisbon earthquake, with an epicenter SW of Portugal, which killed 6 people in Terceira island. It is also noted the teletsunami generated by the 1761 earthquake, located in the same region as the latest, and the one generated in 1929 by an earthquake-triggered submarine landslide in the Grand Banks of Newfoundland. From the local events, originated in the Azores, the most significant were the tsunamis triggered by 1757 and 1980 earthquakes, both associated with the Terceira Rift dynamics. In the first case the waves may also be due to earthquake-triggered. With respect to tsunamis triggered by sea cliffs landslides it is important to mention the 1847 Quebrada Nova and the 1980 Rocha Alta events, both located in the Flores Island. The 1847 event is the deadliest tsunami recorded in Azores since 10 people died in Flores and Corvo islands in result of the propagated wave. The developed studies improve knowledge of the tsunami sources that affected the Azores during its history, also revealing the importance of awareness about this natural phenomenon. The obtained results showed that the tsunami hazard in the Azores is mostly driven from the events triggered by distant earthquakes and local earthquakes and landslides. In this context, were identified 12 tsunami events. In another context, it were identified 6 events associated with coastal areas flooding due to floods and/or extreme weather phenomena, hypothetically identified as meteotsunamis. It should be stressed that, despite the differences associated with their triggering mechanisms, both the tsunamis generated by geological factors and those related to atmospheric phenomena may have similar impact. Although the absence of reports identifying tsunamis associated with volcanic activity, the eruptive history of the Azores active volcanoes shows high magnitude eruptions with considerable tsunamigenic potential.

    Full Text Available Bakgrunn: Revmatoid artritt (RA er en kronisk inflammatorisk leddsykdom som gir økt sykelighet og dødelighet. Nye biologiske legemidler har de siste 10 årene bedret prognosen betydelig. I 2005 ble QUEST-RA (Quantitative Standard Monitoring of Patients with Rheumatoid Arthritis prosjektet etablert for å sammenligne sykdomsstatus og behandling hos RA-pasienter i forskjellige land. I denne artikkelen presenteres status for RA-pasienter i Norge sammenlignet med andre europeiske land og USA.Materiale og metode: Tilfeldig utvalgte RA-pasienter fulgt opp ved revmatologisk poliklinikk ved Sørlandet sykehus i Kristiansand (n=100 og St. Olavs Hospital i Trondheim (n=100 ble inkludert. I henhold til protokoll ble demografiske, sykdoms- og behandlingsdata registrert.Resultater: Norske RA-pasienter skilte seg lite fra gjennomsnittet i andre land med hensyn til alder, utdannelse og sykdomsvarighet. Sykdomsalvorlighet og sykdomsstatus til norske RA-pasienter er sammenlignbare med pasienter fra land som har lavest sykdomsaktivitet og best helsestatus. I Norge er andelen som behandles med biologiske legemidler ca 30%, og Norge er blant de land med størst andel pasienter som behandles med denne legemiddelgruppen. Fortolkning: RA-pasienter i Norge er blant de i Europa som har lavest sykdomsaktivitet. En årsak antas å være den relativt utbredte bruken av biologiske legemidler i Norge.

  3. A comparison of asphaltene model compounds and asphaltenes. The island vs. archipelago models

    Energy Technology Data Exchange (ETDEWEB)

    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.

  4. A Discrete Particle Swarm Optimization Algorithm for Archipelago Berth Allocation Problem

    Directory of Open Access Journals (Sweden)

    Jianliang Peng

    2014-07-01

    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.

    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.

  19. 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.

    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...

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

    Science.gov (United States)

    Michon, Laurent

    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.

    2015-03-01

    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 μg m−3, respectively, followed by organics (2.3 and 4.4 μg m−3 and ammonium (1.5 and 1.7 μg m−3. Aerosol concentrations smoothly decline aloft, reaching lower values (< 1 μg 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.

    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

    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.

    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.

    This paper presents the first actual information on the geology of Jeannette Island, one of the islands of the De Long archipelago located in the East Siberian Sea. We show that Jeannette Island has a volcano-sedimentary section dominated by volcaniclastic turbidites. The sequence identified on the southwestern coast of the island has a submonoclinal plunge complicated by secondary deformation structures, which indicate a general E-W direction of tectonic transport (in present-day coordinates). The sequence is intensely cut by multiple thin (up to a few meters) gabbro-dolerite dikes that are deformed conformably with the host rocks. The general geological framework of the island bears a close resemblance to that of nearby Henrietta Island located some 70 km to the east, which consists of a volcano-sedimentary cover of Early Paleozoic age. No organic remains have been found in the studied section of Jeannette Island. The preliminary results of isotope geochronological and paleomagnetic studies confirm the Late Precambrian-Early Paleozoic age assigned to the entire rock complex of Jeannette Island. The measured paleomagnetic directions are generally consistent with the directions of Lower Paleozoic rocks of Bennett Island (De Long archipelago) and Kotelny Island (Anzhu archipelago), which confirms our earlier conclusion that the New Siberian Islands shared a common tectonic history and that this structural element of the Arctic shelf appears to have been a terrane during the Early Paleozoic. This new information can help elucidate the possible relations between the marginal-continental, shelf, island and deep-seated structures of the Eastern Arctic.

    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.

  4. New Paleomagnetic Data for the Franz Josef Land Archipelago and their Tectonic Consequences

    On the base of field work on the Franz Josef Land archipelago (FJL) in 2010 and 2011 the new paleomagnetic data are obtained from the Jurassic-Early Cretaceous magmatic complexes. 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.

    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.

    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...

  10. 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

    The Archipelago of San Andrés and Providencia is a Colombian Department in the western waters of the Caribbean Sea. Most of its inhabitants belong to the African-Colombian group known as raizal. This group has unique cultural traits that are derived from centuries of admixture of the primarily African slaves and European colonists. Currently, not much is known about the genetic profile of this population. Therefore, this study aimed to determine the Y-chromosome STR genetic structure and relationship to previously published reference populations. A total of 54 natives from the islands were selected based on the genealogical criterion of having three generations of ancestors born in the Archipelago. Seventeen Y-STRs were analyzed, supplemented by information on the first surname inherited. The genetic substructure hypothesis in the studied islands was tested, and no significant differences were found (p>0.05). Y-chromosome haplogroups were predicted, and E1b1a and R1b were the most commonly found haplogroups. They account for more than 80% of the sample. The E1b1a and R1ba haplogroups are common in the African and European populations, respectively. For comparative genetic analysis, genetic distances were calculated with respect to populations from the Caribbean, Colombia, Europe and Africa. We found greater similarity between the African and Caribbean populations. The surname analysis demonstrated that most of the time, the "raizales" with the same surname also shared the same Y-STR haplotype. This suggests that some kinship relationship exists between participants with the same surname, which was confirmed by the haplotype diversity levels found in the studied islands. PMID:23290785

    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

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

    Continental shelf island systems, created by rising sea levels, provide a premier setting for studying the effects of geographical isolation on non-adaptive radiation and allopatric speciation brought about by genetic drift. The Aegean Archipelago forms a highly fragmented complex of mostly continental shelf islands that have become disconnected from each other and the mainland in relatively recent geological times (ca Cyclades), is shown to be strongly conditioned by (palaeo)geographic factors (including changes in sea level), shifts in breeding system (selfing) and associated isolating mechanisms have also contributed to this radiation. By contrast, founder event speciation has probably played only a minor role, perhaps reflecting a migratory situation typical for continental archipelagos characterized by niche pre-emption because of a long established resident flora. Overall, surveys of neutral molecular markers in Aegean Nigella have so far revealed population genetic processes that conform remarkably well to predictions raised by genetic drift theory. The challenge is now to gain more direct insights into the relative importance of the role of genetic drift, as opposed to natural selection, in the phenotypic and reproductive divergence among these Aegean plant species.

    Full Text Available The Archipelago Sea in the Northern Baltic Sea has a complex water quality regime. The region consists of islands and underwater thresholds that separate interconnected sub-basins, where the waters from the adjacent sea areas and discharges from the mainland are mixed. Thus, the water properties in the region are exceptionally varying by season and location. We studied the seasonal developments of five surface-layer water variables – temperature, salinity, Secchi depth, chlorophyll and acidity – and the persistence of their geographical patterns in a network of 20 sampling stations in the eastern part of the Archipelago Sea during a period from May to October in 2007. Furthermore, the inter-annual persistence of the late summer observations of three of these variables were analysed within the same network. Although preconceptions about the general gradation patterns from the mainland towards the open sea were found realistic, we also identified geographically divergent seasonal developments and found out that the inter-annual persistence of the studied three variables were not geographically as strong as expected.

  16. 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 idea of connecting the islands of the area with the mainland and interconnecting them is also taken into consideration

  17. Mechanisms of coexistence and competition between ants and land hermit crabs in a Bahamian archipelago

    Ants and land crabs are common inhabitants of many coastal and insular communities across the tropics and subtropics, and yet direct evidence of interspecific competition between ants and land crabs has only recently been documented. I conducted a series of observational and manipulative experiments to further elucidate the mechanisms of competition, as well as coexistence, in these two groups in an archipelago of small Bahamian islands. Diel baiting trials demonstrated a significant temporal difference in foraging activity between the land hermit crab, Coenobita clypeatus (Herbst), and ant Brachymyrmex obscurior Forel, suggesting this is one mechanism underlying their coexistence on small oceanic islands. Reciprocal manipulative baiting experiments, in which one of a pair of species was removed from baits, documented that aggressive interspecific interactions underlie patterns of complementary distribution and temporal turnover at rich food resources. This was true for competition between hermit crabs and B. obscurior, and between B. obscurior and a second ant species, Dorymyrmex pyramicus Roger. Negative species associations at baits were found to be common throughout an archipelago of 69 small islands. A trade-off in exploitative and interference abilities may be a second mechanism allowing species coexistence on these small islands. Interspecific interactions such as competition and predation may occur commonly between ants and land crabs and have important consequences for the structure and function of tropical and subtropical insular ecosystems.

    Observed variations in dolphin acoustic signals may be associated with behavior, social composition, and local differences in habitat features. This study aims at characterizing whistles emitted by the spinner dolphin population occurring in the waters of the main island of the Archipelago of Comoros (Mozambique Channel, Indian Ocean) and to assess factors possibly influencing the acoustic structure of signals. All parameters examined on 953 whistles significantly differed in relation to environmental conditions, group size, and behavior. By mixed model analysis, it was found that only habitat characteristics play a role in the variation of frequency parameters, and exerted on the acoustic structure of whistles stronger influence than socio-behavioral factors. Spinner dolphins occurring in the Comoros archipelago use higher frequencies and show longer signal duration compared to those from the Pacific and the Atlantic. Results suggest that frequency parameters are distinctive of the local population and reflect the habitat use of the species in the area. In conclusion, acoustic measurements may be crucial elements to be included in monitoring programs to identify local peculiarities of dolphins' populations. PMID:26627799

    The interpretation of the extent of late Wisconsin glaciation in southeastern Alaska has varied between geologists and biologists. Maps and reports of the region prepared by geologists commonly indicated that late Wisconsin ice extended as a large uniform front west to the edge of the continental shelf. However, the distribution of plants and animals in the region has led many biologists to suggest that there may have been ice-free areas that served as refugia during the late Wisconsin. Based on analyses of aerial photographs, topographic maps, and bathymetric charts, in conjunction with a review of previous literature and reconnaissance fieldwork throughout the region, this study presents data supporting a limited ice extent in the Alexander Archipelago during the late Wisconsin and identifies possible ice-free areas that may have served as refugia. These areas include (1) the Fairweather Ground, (2) the Herbert Graves Island area, (3) the western coast of southern Baranof Island and adjacent continental shelf, (4) Coronation Island and the adjacent continental shelf, (5) the Warren Island area, (6) the continental shelf from west of Heceta Island to Forrester Island in the south, (7) parts of the west coast of southern Dall Island, and (8) lowland areas in southern Prince of Wales Island. The identification of these possible refugia has bearing on the recolonization of the Alexander Archipelago, as they could have served as centers of biotic dispersal upon regional deglaciation and as stepping stones for early humans with a maritime tradition entering the western hemisphere from Asia. ?? 2007 NRC Canada.

    Efforts to limit the impact of invasive species are frustrated by the cryptogenic status of a large proportion of those species. Half a century ago, the state of Hawai'i introduced the Bluestripe Snapper, Lutjanus kasmira, to O'ahu for fisheries enhancement. Today, this species shares an intestinal nematode parasite, Spirocamallanus istiblenni, with native Hawaiian fishes, raising the possibility that the introduced fish carried a parasite that has since spread to naïve local hosts. Here, we employ a multidisciplinary approach, combining molecular, historical, and ecological data to confirm the alien status of S. istiblenni in Hawai'i. Using molecular sequence data we show that S. istiblenni from Hawai'i are genetically affiliated with source populations in French Polynesia, and not parasites at a geographically intermediate location in the Line Islands. S. istiblenni from Hawai'i are a genetic subset of the more diverse source populations, indicating a bottleneck at introduction. Ecological surveys indicate that the parasite has found suitable intermediate hosts in Hawai'i, which are required for the completion of its life cycle, and that the parasite is twice as prevalent in Hawaiian Bluestripe Snappers as in source populations. While the introduced snapper has spread across the entire 2600 km archipelago to Kure Atoll, the introduced parasite has spread only half that distance. However, the parasite faces no apparent impediments to invading the entire archipelago, with unknown implications for naïve indigenous Hawaiian fishes and the protected Papah?naumoku?kea Marine National Monument.

  1. Development of a Hindcast/Forecast Model for the Philippine Archipelago

    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.

  2. Upper mantle structure beneath the Galápagos Archipelago from joint inversion of body and surface waves (Invited)

    We conducted a joint tomographic study of teleseismic body-wave delay times and Rayleigh-wave phase velocities to constrain the seismic structure of the upper mantle beneath the Galápagos Archipelago. Data are from 10 broadband stations deployed over a period of 3 years and one station of the Global Seismographic Network. The seismic network spanned an area of 200 by 300 km2, and the station spacing was 50-70 km. We measured 1783 P wave delay times and 1000 S wave delay times from 110 teleseismic events, and we used 12 maps of lateral variation of Rayleigh-wave phase velocity at periods from 20 s to 125 s obtained by us earlier. We invert simultaneously the delay times and phase velocities for three-dimensional variations in P and S wave velocity VP and VS, and we allow for variable weighting of body and surface wave data and coupling of P and S wave structures. The inversion solutions contain low-velocity anomalies that extend from the surface to the maximum depth of resolution (~300 km). We interpret the low-velocity volume at depths greater than ~100 km to be the locus of an upwelling mantle plume. Between 300 and 100 km depth the low-velocity anomaly is nearly cylindrical with a radius of ~75 km, and the VS anomaly reaches a magnitude of -2%. We attribute this reduction to a combination of higher-than-normal temperature and partial melt. The low-velocity anomaly tilts northward as it shoals; at 300 km depth it is centered ~75 km to the south of Isabela, whereas at 100 km depth it is centered beneath that island. We propose that the northward tilt of the plume as it rises is due to background mantle flow toward the Galápagos Spreading Center. At the top of the low-velocity volume is a rapid increase in VS, which we term the high-velocity lid. We attribute the base of this lid, which is at varying depth across the archipelago and is deepest (~100 km) beneath the southern end of Isabela, to a compositional change produced by the depletion and dehydration resulting from melt extraction. The viscosity increase associated with such dehydration may decrease or stall mantle upwelling, resulting in lateral spreading of the plume. Between 50 and 100 km depth, the low-velocity anomaly is located beneath the northeastern part of the archipelago, a pattern we attribute to melting produced as upwelling mantle spreads toward a region with a thinner lid. There is a pronounced low-velocity anomaly (maximum VS anomaly of -3%) at depths shallower than 50 km beneath the southwestern part of the archipelago that we attribute to another stage of melting of mantle driven upward by plume flow and residuum buoyancy. This anomaly lies beneath Fernandina and Isabela, sites of the most active volcanoes in the archipelago. Our results support the interpretation that the Galápagos Islands are the product of an upwelling thermal plume that is continuous from at least 300 km depth to the base of a high-velocity lid and also suggest that mantle flow and melting beneath the Galápagos are influenced by the formation of residuum. In support of the last inference, the thickness of the high-velocity lid correlates well with regional variations in lava geochemistry.

    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.

  7. Sintered materials studied by SANS

    International Nuclear Information System (INIS)

    Complete text of publication follows. The small angle scattering of compacted and sintered single phase materials with open or closed porosity can be described by the two phase model. During sintering, the decrease of pore volume is accompanied with decreasing internal surface measured by SANS [1]. Such investigation can be extended to the field of technically relevant multiphase materials as well, e.g. doped tunsten, SiN ceramics and WC-Co composite made from nano-crystalline powder. The deformation of remaining porosity after sintering can be monitored by 2D anisotropy of SANS distribution as the sintered body is processed through several steps of thermomechanical treatment. The elongation of pores or stable bubbles, e.g. K gas filled bubbles in doped W [2], follows the macroscopic deformation of the body. Heat treatment, however, causes spheroidization with vanishing SANS anisotropy. Our investigation using the isointensity contour map method allows establishing a new description of mechanisms of thermomechanical processing. (author) [1] O. Blaschko, R. Glas, G. Krexner and P.

    The Class 2 Project at West Welch was designed to demonstrate the use of advanced technologies to enhance the economics of improved oil recovery (IOR) projects in lower quality Shallow Shelf Carbonate (SSC) reservoirs, resulting in recovery of additional oil that would otherwise be left in the reservoir at project abandonment. Accurate reservoir description is critical to the effective evaluation and efficient design of IOR projects in the heterogeneous SSC reservoirs. Therefore, the majority of Budget Period 1 was devoted to reservoir characterization. Technologies being demonstrated include: (1) Advanced petrophysics; (2) Three-dimensional (3-D) seismic; (3) Crosswell bore tomography; (4) Advanced reservoir simulation; (5) Carbon dioxide (CO{sub 2}) stimulation treatments; (6) Hydraulic fracturing design and monitoring; and (7) Mobility control agents.

    The OXY-operated Class 2 Project at West Welch is designed to demonstrate how the use of advanced technology can improve the economics of miscible CO{sub 2} injection projects in lower quality Shallow Shelf Carbonate reservoirs. The research and design phase (Budget Period 1) primarily involved advanced reservoir characterization. The current demonstration phase (Budget Period 2) is the implementation of the reservoir management plan for an optimum miscible CO{sub 2} flood design based on the reservoir characterization. Although Budget Period 1 for the Project officially ended 12/31/96, reservoir characterization and simulation work continued during the Budget Period 2. During the seventh annual reporting period (8/3/00-8/2/01) covered by this report, work continued on interpretation of the interwell seismic data to create porosity and permeability profiles which were distributed into the reservoir geostatistically. The initial interwell seismic CO{sub 2} monitor survey was conducted and the acquired data processed and interpretation started. Only limited well work and facility construction were conducted in the project area. The CO{sub 2} injection initiated in October 1997 was continued, although the operator had to modify the operating plan in response to low injection rates, well performance and changes in CO{sub 2} supply. CO{sub 2} injection was focused in a smaller area to increase the reservoir processing rate. By the end of the reporting period three producers had shown sustained oil rate increases and six wells had experienced gas (CO{sub 2}) breakthrough.

  15. Local Culture as a Resource in Regional Development in the Southwest-Finland Archipelago

    Directory of Open Access Journals (Sweden)

    Katriina Siivonen

    2009-12-01

    Full Text Available In cultural and regional politics in the European Union, and in practice for instance in the Southwest-Finland Archipelago, local culture and cultural heritage are considered resources. Global boundlessness, heterogeneity and change are basic qualities of culture. However, in regional development, culture is seen and used as a number of different local cultures with their own essential cultural heritage. The culture of local everyday life is opposite to, and in tension with, the construct of cultures used in regional development. Accordingly, culture should primarily be safeguarded as a heterogenic, dynamic and interactive process of everyday life. This process is the most important resource of local culture. In addition, culture should be safeguarded as value-based cultural constructions, such as brands or common identities of certain cultures, with for instance cultural heritage as a part of it. In the latter case, a common, transparent definition of these brands, identities and cultural heritages with their different values, is needed.

    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.

    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...

    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.

    The Canary Archipelago is an active volcanic region located in the African plate, at 100 Km of the northwest coast of Africa. The Complutense University of Madrid, Institute of Astronomy and Geodesy (CSIC-UCM) and University of Jaén, established a GPS Network in this region and carried out six observations campaigns from 2002 to 2009. The focus of thiswork is processing and analyzing these observations to study the geodynamic behavior of the stations of this network. The data have been computed with the Bernese GPS Software Version 5.0 obtaining individual solutions of coordinates for each session and campaign, the coordinate velocities of the stations and the time series of baselines formed between them. Results show consistency of station velocities compared to behaviour of areas permanent stations and baselines stability. No deformations could be detected.

    Full Text Available Green Jacks, Caranx caballus, are distributed along the Eastern Pacific coast. In Panama, C. caballus was heavily fished around Las Perlas Archipelago to sustain local markets until 2007, when the archipelago was declared a marine protected area. This first study in Panama, analyzed a sample of 4 990 individuals from Las Perlas, obtained monthly from June 2005 to June 2006, from landings at the central fish market. Average total length was 36.1±6.4cm and optimum length 38.9cm. Approximately 68% of fish lengths were within ±10% of the optimal length but only six (15% were considered mega-spawners. The von Bertalanffy parameters describe a long-lived and fast growing species, while mortality rates revealed that C. caballus is under high fishing pressure. Standard length at which half of the population is mature was 38.8cm, and the size at which individuals matured massively, 33cm. Only 10-13% of the fish were immature. C. caballus reproduces two to three times per year, with peaks in December, April, and probably September, and recruits to the population at least twice per year. Catch per unit effort (CPUE was best predicted by minimum annual values of the Multivariate ENSO/ LNSO Index (MEI (R²=0.54. Results show that C. caballus in Pacific Panama is overfished. We recommend the raising of the minimum capture/landing size of this species in order to increase the proportion of megaspawners in the population and guarantee the sustainability of this resource.

  6. Reproductive response to nitrogen and phosphorus fertilization along the Hawaiian archipelago's natural soil fertility gradient.

    DiManno, Nicole M; Ostertag, Rebecca

    2016-01-01

    Nitrogen (N) and phosphorus (P) are the most important nutrients involved in plant reproduction and typically the most limiting in terrestrial ecosystems. The natural soil fertility gradient of the Hawaiian archipelago, in which younger islands are N limited and older islands are P limited, provides a model system to examine questions regarding allocation of nutrients. Using fertilized plots (+N or +P) at the extreme sites of the Hawaiian archipelago, vegetative productivity (e.g., net primary productivity, growth, and litterfall) and foliar nutrient responses have previously been studied for the dominant canopy tree, Metrosideros polymorpha. Here, we investigated whether the reproductive response of M. polymorpha mirrors the previously found vegetative productivity and foliar nutrient responses, by quantifying: (1) inflorescence and seed productivity, and (2) nutrient concentration of reproductive structures. Fertilization with N and P did not significantly affect the productivity of inflorescences or seeds, or seed viability at either site. However, nutrient concentrations increased after fertilization; %P increased in inflorescences in the +P treatment at the P-limited site. Seeds and inflorescences generally contained higher nutrient concentrations than leaves at both sites. Unlike foliar data, reproductive strategies of M. polymorpha differed depending on soil nutrient limitation with emphasis on quality (higher seed viability/greater nutrient concentrations) at the P-limited site. We suggest that in response to P additions M. polymorpha employs a nutrient conservation strategy for its inflorescences and an investment strategy for its seeds. Examining N and P simultaneously challenges a basic assumption that reproductive allocation follows a similar pattern to the often measured aboveground productivity. PMID:26404491

  7. Comparison of Two Independent Mapping Exercises in the Primeiras and Segundas Archipelago, Mozambique

    Full Text Available Production of coral reef habitat maps from high spatial resolution multispectral imagery is common practice and benefits from standardized accuracy assessment methods and many informative studies on the merits of different processing algorithms. However, few studies consider the full production workflow, including factors such as operator influence, visual interpretation and a-priori knowledge. An end-user might justifiably ask: Given the same imagery and field data, how consistent would two independent production efforts be? This paper is a post-study analysis of a project in which two teams of researchers independently produced maps of six coral reef systems of the archipelago of the Primeiras and Segundas Environmental Protected Area (PSEPA, Mozambique. Both teams used the same imagery and field data, but applied different approaches—pixel based vs. object based image analysis—and used independently developed classification schemes. The results offer a unique perspective on the map production process. Both efforts resulted in similar merged classes accuracies, averaging at 63% and 64%, but the maps were distinct in terms of scale of spatial patterns, classification disparities, and in other aspects where the mapping process is reliant on visual interpretation. Despite the difficulty in aligning the classification schemes clear patterns of correspondence and discrepancy were identified. The maps were consistent with respect to geomorphological level mapping (17 out of 30 paired comparisons at more than 75% agreement, and also agreed in the extent of coral containing areas within a difference of 16% across the archipelago. However, more detailed benthic habitat level classes were inconsistent. Mapping of deep benthic cover was the most subjective result and dependent on operator visual interpretation, yet this was one of the results of highest interest for the PSEPA management since it revealed a continuity of benthos between the islands and the impression of a proto-barrier reef.

    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.

    Smith, Stephen H; Marx, Donald E

    2016-01-15

    Fourteen surveys were conducted at Farallon De Medinilla (a U.S. Department of Defense bombing range in the Mariana Archipelago) between 1997 and 2012; annual surveys were conducted from 1999 through 2012. There was no evidence that the condition of the biological resources assessed had changed, or been adversely impacted to a significant degree by the training activities being conducted there. Restricted access has resulted in a de-facto preserve effect and outweighs minor negative impacts from training. The health, abundance and biomass of fishes, corals and other marine resources are comparable to or superior to those in similar habitats at other locations within the Mariana Archipelago. Our research suggests that the greatest threat to FDM's marine resources is from fishermen, not military training activities. PMID:26621576

  20. RheoSANS: simultaneous SANS and rheology measurements on the Quokka SANS instrument

    International Nuclear Information System (INIS)

    The highly penetrative and non-ionising nature of neutrons make the SANS measurement particularly suited to examine toe response of soft materials to an external stimulus. In this case we consider the response of a complex fluid. an aqueous solution of a block co-polymer. to shear flow in a couette cell consisting of two concentric quartz cylinders with a variable gap between The couette shear cell is connected to a commercial Paar Physica MCR 500 rheometer. Depending on the ability to maintain laminar flow, rheometric tests may be performed at shear rates from 0.1 to 2000s-1 and at temperatures from -5 to 80cC. The jacket responsible for thermal control of the sample allows access of neutron beam in directions radial and tangential to the now direction. In the tangential direction the need to use a highly collimated beam to illuminate the gap provides a serious limitation to neutron flux at the sample. A trap may be used to prevent the evaporation of solvents. SANS data from the detector may be acquired in either of two modes. Acquisitions may be triggered by voltage output from rheometer (e.g shear rate), or using the detector in list mode where detector counts are post-binned to provide the optimal signal to noise for example in kinetic studies. A further possibility of the latter mode rs the study of shear induced structural changes in a steady perturbed slate such as an oscillatory smear.

    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 (

  1. 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

    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.

    Full Text Available Abstract – One of the major components of any enterprise IT infrastructure is data storage. There has been continuous effort to explore new storage technologies to improve performance with respect to input/output operations, data availability, consolidation of storage assets and data protection and archiving. Storage has moved from the traditional Direct Attached Storage (DAS to Network Attached Storage (NAS and now to Storage Area Networks (SAN. Traditional storage subsystems like Server Attached Storage (SAS and Network Attached Storage (NAS use disks directly attached to servers over a Small Computer Systems Interface (SCSI bus. However, these have limited capabilities keeping in view the rapidly expanding storage needs. The SAN technology holds great promises to be used for enterprises where issues like data availability, serviceability, consolidation of storage and reliability are major concerns. It can provide high speed data transfer with many other storage services, backboned with a high speed Fibre Channel (FC. Storage-area networks are also more popular and efficient way of building large storage systems both in an enterprise environment and for multi-domain storage service providers. SAN design and implementation requires careful analysis before SAN can be used as an enterprise storage solution. In this paper we provide an overview of SAN technology from the view point of building large storage systems in an enterprise environment. We also discuss on return on investment (ROI which can justify the adoption of SAN in an enterprise. Further, it compares two specific technologies, namely, FC SAN and IP SAN. In the sequel different design considerations are made to recommend suitable SAN implementations in order to meet the requirements of any enterprise.

  4. SANS studies of micellar and magnetic fluids

    International Nuclear Information System (INIS)

    Small-angle neutron scattering (SANS) has proved to be an excellent technique for the study of complex fluids. This article introduces SANS from the viewpoint of such studies. The use of SANS to determine the structures of concentrated micellar fluids is then discussed within the framework of current one-component macrofluid (OCM) models, and experimental examples are taken from several contemporary studies. Finally, the discussion is extended to magnetic fluids (ferrofluids) in which the neutron magnetic interaction plays an important experimental role. 25 refs., 11 figs., 1 tab

    We report small angle neutron scattering (SANS) experiments on two crude oils. Analysis of the high-Q SANS region has probed the asphaltene aggregates in the nanometer length scale. We find that the radius of gyration decreases with increasing temperature. We show that SANS measurements on crude oils give similar aggregate sizes to those found from SANS measurements of asphaltenes redispersed in deuterated toluene. The combined use of SANS and V-SANS on crude oil samples has allowed the determination of the radius of gyration of large scale asphaltene aggregates of approximately 0.45 microm. This has been achieved by the fitting of Beaucage functions over two size regimes. Analysis of the fitted Beaucage functions at very low-Q has shown that the large scale aggregates are not simply made by aggregation of all the smaller nanoaggregates. Instead, they are two different aggregates coexisting. PMID:19063643

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

    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

    The community structure of intertidal macrobenthos in Changdao Archipelago (north of Shandong Peninsula, between Bohai Bay and the northern Yellow Sea) was examined based on samples collected from 14 stations in five transects in June 2007. Three stations corresponding to high, medium and low tidal areas were set up for each transect. A total of 68 macrobenthic species were found in the research region, most of which belonged to Mollusca and Crustacea. The average abundance and biomass of the macrobenthos was 1 383 ind./m2 and 372.41 g/m2, respectively. The use of an arbitrary similarity level of 20% resulted in identification of five groups among the 14 stations in the research region. There were remarkable differences in the biomass, abundance and Shannon-Wiener diversity index of the different sediments. Specifically, the order of biomass was rocky shores > gravel > mud-sand > coarse sand > stiff mud, while the order of abundance was rocky shores > coarse sand > mud-sand > gravel > stiff mud, and that of the diversity index was mud-sand > gravel > stiff mud > rocky shores > coarse sand. The above results revealed that the sediment type was the most important factor affecting the structure of the macrobenthic community of the intertidal zone.

    Following a global coral bleaching event in 1998, Acropora corals surrounding most of Okinawa island (OI) were devastated, although they are now gradually recovering. In contrast, the Kerama Islands (KIs) only 30?km west of OI, have continuously hosted a great variety of healthy corals. Taking advantage of the decoded Acropora digitifera genome and using genome-wide SNP analyses, we clarified Acropora population structure in the southern Ryukyu Archipelago (sRA). Despite small genetic distances, we identified distinct clusters corresponding to specific island groups, suggesting infrequent long-distance dispersal within the sRA. Although the KIs were believed to supply coral larvae to OI, admixture analyses showed that such dispersal is much more limited than previously realized, indicating independent recovery of OI coral populations and the necessity of local conservation efforts for each region. We detected strong historical migration from the Yaeyama Islands (YIs) to OI, and suggest that the YIs are the original source of OI corals. In addition, migration edges to the KIs suggest that they are a historical sink population in the sRA, resulting in high diversity. This population genomics study provides the highest resolution data to date regarding coral population structure and history. PMID:26656261

    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

    Full Text Available Karimunjawa archipelago, marine national park, has been considered to be a relatively pristine area that have more than 90 species of corals. This study was conducted to detect any concentrations heavy metal levels in the tissues of eight coral species. Based on life-forms, selected coral species are classified as massive (Porites lutea and Goniastrea retiformis, submassive (Galaxea fascicularis and Stylophora pistillata, foliaceous (Pavona decussata and Montipora foliosa and branching/ramosa (Acropora aspera and Pocillopora damicornis. The concentration of heavy metals in the coral tissues were assessed using Atomic Absorption Spectrophotometer (AAS technique. The present experimental results demonstrated that metal in coral tissues were no significant difference between sites. Concentration levels of five heavy metals were found to be in the order of Pb>Zn>Cr>Cd>Cu. Relating heavy metal concentrations to life-form corals, there were no significant differences of all the metals (except Pb, the highest concentration of Pb were found in foliaceous type of corals. The high level of Pb in foliaceous coral life-form (Pavona decussata and Montipora foliosa, indicating that these coral species are usefull as potential candidates of biomonitoring material for this metal. However, the use of corals as biomonitors should be considered carefully in biological and local environmental factors.

    The appearance of farming, from its inception in the Near East around 12 000 years ago, finally reached the northwestern extremes of Europe by the fourth millennium BC or shortly thereafter. Various models have been invoked to explain the Neolithization of northern Europe; however, resolving these different scenarios has proved problematic due to poor faunal preservation and the lack of specificity achievable for commonly applied proxies. Here, we present new multi-proxy evidence, which qualitatively and quantitatively maps subsistence change in the northeast Atlantic archipelagos from the Late Mesolithic into the Neolithic and beyond. A model involving significant retention of hunter-gatherer-fisher influences was tested against one of the dominant adoptions of farming using a novel suite of lipid biomarkers, including dihydroxy fatty acids, ?-(o-alkylphenyl)alkanoic acids and stable carbon isotope signatures of individual fatty acids preserved in cooking vessels. These new findings, together with archaeozoological and human skeletal collagen bulk stable carbon isotope proxies, unequivocally confirm rejection of marine resources by early farmers coinciding with the adoption of intensive dairy farming. This pattern of Neolithization contrasts markedly to that occurring contemporaneously in the Baltic, suggesting that geographically distinct ecological and cultural influences dictated the evolution of subsistence practices at this critical phase of European prehistory.

    The Shompen, one of the most isolated and poorly understood contemporary hunter-gatherer populations, inhabit Great Nicobar Island, the southernmost island of the Nicobar archipelago. Morphological imprints in the Shompen were interpreted to favour a mixed Indo-Chinese, Malay, Negrito and Dravidian origin. Analyses of the mitochondrial, Y-chromosomal and autosomal gene pool of contemporary Shompen have revealed low diversity, illustrating a founder effect in the island population. Mitochondrial sequence analyses revealed the presence of two haplogroups of R lineage: B5a, and a newly defined clade, R12. Y-chromosomal analyses demonstrated the occurrence of a single lineage found predominantly in Austro-Asiatic speakers across Asia. With the different types of genetic markers analysed, the Shompen exhibit varying levels of genetic relatedness with the Nicobarese, and Austro-Asiatic speakers of mainland India and Southeast Asia. These genetic analyses provide evidence that the Shompen, an offshoot of the Nicobarese, are descendants of Mesolithic hunter-gatherers of Southeast Asian origin, deriving from at least two source populations.

    2015-03-01

    The spatial distribution of oxygen and hydrogen isotopic composition (?18O and ?2H) of stream waters across Japan was clarified with a data set by 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.

    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.

  16. 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

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.

    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.

    Sediment plays an important role in the ecological health of rivers and estuaries and consequently is an important issue for water-resource managers. To better understand sediment characteristics in the San Antonio River Basin, the U.S. Geological Survey, in cooperation with the San Antonio River Authority, completed a two-part study in the San Antonio River Basin downstream from San Antonio, Texas, to (1) collect and analyze sediment data to characterize sediment conditions and (2) develop and calibrate a watershed model to simulate hydrologic conditions and suspended-sediment loads during 2000–12.

    1981-07-01

    Reticulitermes flavipes andR. virginicus have been examined for the presence and possible defense functions of soldiers specific secretions. The cephalic extracts for soldiers of both species contained the identical two major sesquiterpenes which were absent from other castes. The sesquiterpenes have been identified as ?1-cadinene (I) and the corresponding aldehyde (II) by high-resolution nuclear magnetic resonance spectrometry using homonuclear proton decoupling and by high-resolution mass spectrometry. When groups of termite soldiers were exposed to foraging parties of the sympatric native fire ant,Solenopsis geminata, the termites utilized only mechanical defenses. No evidence was obtained to indicate that the ants had been sprayed or coated with either an irritant or toxicant, and there was no evidence that an alarm had been promulgated. PMID:24420686

    In a few short days in September of this year, the ocean color/ocean optics community lost two of the founding members of its Hall of FameCharles Yentsch and Andre Morel. Yentsch passed away at the age of 85 on September 19, and Morel passed away on September 23 at the age of 79. It might sound clich to say that someone was instrumental to the advance of science in a particular field, but in the case of Yentsch and Morel and ocean color instrumentation, such an assessment would likely be accurate. Each mans career complimented that of the other Yentsch was one of the first to make measurements of the light field of the ocean from altitude and to advocate an instrument in space that could observe the spectrum of ocean radiance Morels theoretical underpinnings established a firm foundation for the measurements such an instrument could make, allowing their successful interpretation.

The present study was aimed to focus on the extraction and screening of alkaloids from Epipremnum aureum (Linden and Andre Bunting. It has been observed that the plant is very rich in alkaloids and the modified method employed for the extraction of alkaloid is efficient and selective, where the interference of other secondary metabolites is negligible. The identification of each compound was made through gas chromatography-mass spectrometry (GC-MS. A total of twenty six structurally different alkaloids were identified for the first time from this plant. E. aureum is highly rich in alkaloids and twenty six different alkaloids were characterized. The present study may help in the field of natural products’ chemistry and pharmaceuticals as well as drug discovery science and technology.

  3. San Onofre Unit 1 decommissioning

    International Nuclear Information System (INIS)

    Nuclear plant decommissioning presents several challenges in radiation protection. The plant demolition must consider radiation protection for workers, protection of the public, and careful material management. Decommissioning of the San Onofre Nuclear Generating Station (SONGS) Unit 1 presented some additional challenges. Including complete removal of above ground structures this can be accomplished safely and efficiently. None of the low-level radioactive waste is unique to decommissioning although transportation of large components can be a significant challenge. Proven techniques are available to handle Greater than Class C waste (highly activated reactor internals) and spent fuel. A considerable challenge is the disposing of the very large volume of potentially clean material. There is a high cost to survey and decontaminate materials. Moreover, in the US today there are no standards for the clearance of potentially contaminated volumetric materials. Careful planning is necessary to determine the most cost-effective means for waste management, whether it includes decontamination and surveys or simple disposal. Lastly, existing ALARA programs with some minor modifications provide sufficient worker and public protection from radiation

  5. Abrupt along-strike change in tectonic style: San Andreas fault zone, San Francisco Peninsula

    1999-01-01

    Seismicity and high-resolution aeromagnetic data are used to define an abrupt change from compressional to extensional tectonism within a 10- to 15-km-wide zone along the San Andreas fault on the San Francisco Peninsula and offshore from the Golden Gate. This 100-km-long section of the San Andreas fault includes the hypocenter of the Mw = 7.8 1906 San Francisco earthquake as well as the highest level of persistent microseismicity along that ???470-km-long rupture. We define two distinct zones of deformation along this stretch of the fault using well-constrained relocations of all post-1969 earthquakes based a joint one-dimensional velocity/hypocenter inversion and a redetermination of focal mechanisms. The southern zone is characterized by thrust- and reverse-faulting focal mechanisms with NE trending P axes that indicate "fault-normal" compression in 7- to 10-km-wide zones of deformation on both sides of the San Andreas fault. A 1- to 2-km-wide vertical zone beneath the surface trace of the San Andreas is characterized by its almost complete lack of seismicity. The compressional deformation is consistent with the young, high topography of the Santa Cruz Mountains/Coast Ranges as the San Andreas fault makes a broad restraining left bend (???10??) through the southernmost peninsula. A zone of seismic quiescence ???15 km long separates this compressional zone to the south from a zone of combined normal-faulting and strike-slip-faulting focal mechanisms (including a ML = 5.3 earthquake in 1957) on the northernmost peninsula and offshore on the Golden Gate platform. Both linear pseudo-gravity gradients, calculated from the aeromagnetic data, and seismic reflection data indicate that the San Andreas fault makes an abrupt ???3-km right step less than 5 km offshore in this northern zone. A similar right-stepping (dilatational) geometry is also observed for the subparallel San Gregorio fault offshore. Persistent seismicity and extensional tectonism occur within the San Andreas right stepover region and at least 15 km along-strike both to the SE and NW. The 1906 San Francisco earthquake may have nucleated within the San Andreas right stepover, which may help explain the bilateral nature of rupture of this event. Our analysis suggests two seismic hazards for the San Francisco Peninsula in addition to the hazard associated with a M = 7 to 8 strike-slip earthquake along the San Andreas fault: the potential for a M ??? 6 normal-faulting earthquake just 5-8 km west of San Francisco and a M = 6+ thrust faulting event in the southern peninsula.

    The Indonesian Mixing program (INDOMIX) was designed to quantify the very strong mixing that transforms Pacific waters into isohaline 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 in-situ observations: (1) direct measurements of the dissipation using a microstructure profiler, (2) use of density-based fine-scale methods applied to CTD and XCTD data, 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, found above energetic straits or in relatively quiescent large basins. Strong instabilities, inversions of the density profiles and a very strong water mass transformation were observed. A wide range of dissipation values were obtained (between [10-10, 10-4] W kg-1) with spots of higher dissipation in the ocean interior correlated with a strong internal tide signal. Both the fine-scale and micro-scale methods allow us to identify very strong energy dissipation levels above the straits, ranging between [10-7, 10-4] W kg-1, in contrast to lower values at stations further away from the generation sites. The dissipation for the station located in the center of the Halmahera Sea ([10-9, 10-8] W kg-1) is stronger than for the Banda station ([10-11, 10-10] W kg-1), which is even further away from the generation sites. The three approaches agree relatively well and provide vertical eddy diffusivities 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). CTD and XCTD profilers (deployed between stations) give estimates of dissipation all along the transit. It is found that enhanced mixing occurs preferentially above rough topography, such as in the Ombai Strait, the Halmahera Sea's northern entrance, the Buru strait and Sumba strait. Finestructure parameters are very sensitive to depth and dissipation, which differs between stations. We recommend more systematic microstructure measurement in order to tune these parameters. Surface mixing, at the base of the mixed layer is found to be very strong with values between [10-4, 10-3 m2 s-1]. These results confirm the modeling studies that suggest the occurrence of intensified subsurface mixing which cools the sea surface temperatures and thus strongly affects the mean and variability of the tropical climate. 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.

  8. Temperature Versus Buoyant Mantle Heterogeneities, Evaluating the Origin of OIB Using the Galapagos Archipelago

    The existence of hot mantle plumes has recently been questioned; instead tectonics and shallow low-melting heterogeneities, rather than excess temperatures, have been proposed to explain the upwelling of mantle beneath oceanic islands basalts (OIB) [1]. Geophysical, petrological and geochemical arguments have been used to suggest that enriched heterogeneities located shallow within the upper mantle are buoyant due to either melt retention or water lowering its solidus and consequently triggering early melting of the fertile blobs. Thus, the opponents of the hotspot model have suggested that shallow fertile and buoyant blobs could reproduce the effects of temperature, including isotope gradients, as the cause for the generation of OIB [1]. Uranium-series disequilibria measured in oceanic lavas may provide insight into the origin of OIB that is independent of previous arguments. Earlier works have shown that U-series isotopes in basalts are sensitive to variations in the upwelling rates of their mantle source, and those can be used to invoke upward movements that may be associated with mantle plumes [2-4]. Those work also demonstrated that there exist a significant relationship between the extent of U-series disequilibria and the buoyancy flux beneath OIB; where lower buoyancy fluxes are associated with lower rates of melting and hence higher (230Th/238U) values [2]. However, most of those works have assumed that the effects of source heterogeneity can be neglected relative to the effects of other key parameters. If the increase in melting rates is truly due to the presence of fertile blobs, then there should be a correlation between clear indices of enrichment such as radiogenic isotopes and extent of U-series disequilibrium in OIB. Furthermore, the fertility of the mantle heterogeneities may or may not be associated with the enrichment of water, which has an important effect on the melting rate and consequently in the U-series isotope of the basalts. To evaluate what factors (temperature versus mantle heterogeneity) are controlling the upwelling mantle beneath oceanic islands we used our data (including volatile and U-series isotopes) for lavas from across the Galapagos archipelago combined with previously published results from the adjacent Galapagos Spreading Ridge lavas [5]. These results suggest that the most important factor controlling the variation in mantle upwelling velocities beneath the Galapagos archipelago and adjacent ridge is the difference in mantle temperature.

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

    Science.gov (United States)

    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.

A biomassa e produção de Undinula vulgaris (Dana, 1849), Acrocalanus longicornis Giesbrecht, 1888 e Calocalanus pavo (Dana, 1849) apresentaram diferenças entre alguns transectos. Uma tendência de declínio da biodiversidade e produção com o aumento da distância do arquipélago foi observada, sugerindo que pequenas feições como o ASPSP podem afetar a comunidade em áreas oceânicas oligotróficas tropicais. Abstract in english 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.

En el Archipiélago de Las Perlas, Panamá, la cojinúa fue pescada sin control para sostener mercados locales hasta el 2007, fecha en la que esta región fue declarada área marina protegida. En este [...] primer estudio para Panamá, se analizaron desde junio de 2005 a junio de 2006, 4 990 individuos en las descargas del Mercado Central de Mariscos provenientes de Las Perlas. La longitud media total de esta especie fue de 36.1±6.4cm y la longitud óptima, 38.9cm. Aproximadamente, 68% de los individuos muestreados poseen longitudes dentro de ±10% de la longitud óptima, pero sólo seis (15%) eran mega-reproductores. Los parámetros de la ecuación de von Bertalanffy describen la especie como de larga vida y de rápido crecimiento, mientras que las tasas de mortalidad indican que la cojinúa está bajo una alta presión de pesca. La longitud estándar a la que la mitad de la población es sexualmente madura es 38.8cm y el tamaño de maduración masiva, 33cm. Sólo entre el 10-13% de los individuos muestreados son inmaduros. La cojinúa se reproduce 2-3 veces al año, con picos en diciembre, abril y probablemente septiembre, y recluta a la población por lo menos dos veces al año. Los valores mínimos anuales del Índice ENSO/LNSO multivariado (MEI) son los mejores predictores de la CPUE de esta especie (R²=0.54). Nuestros resultados demuestran que la cojinúa en el Pacífico Panameño está sobreexplotada por lo que recomendamos elevar la talla mínima de captura para permitir que aumente la proporción de mega-reproductores en la población con el fin de garantizar la sostenibilidad del recurso. Abstract in english Green Jacks, Caranx caballus, are distributed along the Eastern Pacific coast. In Panama, C. caballus was heavily fished around Las Perlas Archipelago to sustain local markets until 2007, when the archipelago was declared a marine protected area. This first study in Panama, analyzed a sample of 4 99 [...] 0 individuals from Las Perlas, obtained monthly from June 2005 to June 2006, from landings at the central fish market. Average total length was 36.1±6.4cm and optimum length 38.9cm. Approximately 68% of fish lengths were within ±10% of the optimal length but only six (15%) were considered mega-spawners. The von Bertalanffy parameters describe a long-lived and fast growing species, while mortality rates revealed that C. caballus is under high fishing pressure. Standard length at which half of the population is mature was 38.8cm, and the size at which individuals matured massively, 33cm. Only 10-13% of the fish were immature. C. caballus reproduces two to three times per year, with peaks in December, April, and probably September, and recruits to the population at least twice per year. Catch per unit effort (CPUE) was best predicted by minimum annual values of the Multivariate ENSO/ LNSO Index (MEI) (R²=0.54). Results show that C. caballus in Pacific Panama is overfished. We recommend the raising of the minimum capture/landing size of this species in order to increase the proportion of megaspawners in the population and guarantee the sustainability of this resource.

  5. Intrathermocline eddies at the Juan Fernández Archipelago, southeastern Pacific

    2014-10-01

    Full Text Available Regional Ocean Modeling System (ROMS results, combined with chlorophyll-α (Chl-α 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-α 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-α associated with the eddy were observed, with values up to three times higher than adjacent oceanic waters.

  6. Arctic environments and global change: Evidence in deep permafrost temperatures, Canadian arctic archipelago

    International Nuclear Information System (INIS)

    In considering the role of the polar regions in future global change, one may look toward these regions for evidence of past environmental change. Deep ground temperatures provide one window on past surface temperatures, which may be interpreted in terms not only of past climate but also of past environmental conditions. Across the Canadian Arctic Archipelago, there is no consistent curvature in deep ground temperature profiles that can be modeled in terms of warming of the past century. This contrasts with the result reported by Lachenbruch et al. [1986] for the Prudhoe Bay area of Alaska and may be a consequence of the much larger region and wider well spacing considered in the Canadian case. Any curvature present varies from well to well and may be interpreted in terms of surface temperature changes of the order of 1-3 K on the scale of decades to centuries. However, there is some evidence that these surface temperature histories may arise from long-term changes in paleoenvironmental factors as well as climate. For instance, the paleoclimate derived from oxygen isotope data at the Agassiz Ice Cap has been compared with the geothermal signature at a well some 180 km to the west. For the Little Ice Age (LIA), the Agassiz paleoclimate explains only half the measured variation in ground temperatures at the geothermal site; the remaining variation may be due to other environmental effects, such as an increase in snow cover following the LIA. This is consistent with extrapolated surface temperatures 7 K higher than other Arctic sites and the unusually deep snow cover observed today

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

    In Hawaii, coral reefs occur across a gradient of biological (host abundance), climatic (sea surface temperature anomalies) and anthropogenic conditions from the human-impacted reefs of the main Hawaiian Islands (MHI) to the pristine reefs of the northwestern Hawaiian Islands (NWHI). Coral disease surveys were conducted at 142 sites from across the Archipelago and disease patterns examined. Twelve diseases were recorded from three coral genera (Porites, Montipora, Acropora) with Porites having the highest prevalence. Porites growth anomalies (PorGAs) were significantly more prevalent within and indicative of reefs in the MHI and Porites trematodiasis (PorTrm) was significantly more prevalent within and indicative of reefs in the NWHI. Porites tissue loss syndrome (PorTLS) was also important in driving regional differences but that relationship was less clear. These results highlight the importance of understanding disease ecology when interpreting patterns of disease occurrence. PorTrm is caused by a parasitic flatworm that utilizes multiple hosts during its life cycle (fish, mollusk and coral). All three hosts must be present for the disease to occur and higher host abundance leads to higher disease prevalence. Thus, a high prevalence of PorTrm on Hawaiian reefs would be an indicator of a healthy coral reef ecosystem. In contrast, the high occurrence of PorGAs within the MHI suggests that PorGAs are related, directly or indirectly, to some environmental co-factor associated with increased human population sizes. Focusing on the three indicator diseases (PorGAs, PorTrm, PorTLS) we used statistical modeling to examine the underlying associations between disease prevalence and 14 different predictor variables (biotic and abiotic). All three diseases showed positive associations with host abundance and negative associations with thermal stress. The association with human population density differed among disease states with PorGAs showing a positive and PorTrm showing a negative association, but no significant explanatory power was offered for PorTLS. ?? 2011 Aeby et al.

  9. Summertime sources of dimethyl sulfide in the Canadian Arctic Archipelago and Baffin Bay

    2015-12-01

    Full Text Available Dimethyl sulfide (DMS plays a major role in the global sulfur cycle. In addition, its atmospheric oxidation products contribute to the formation and growth of atmospheric aerosol particles, thereby influencing cloud condensation nuclei (CCN populations and thus cloud formation. The pristine summertime Arctic atmosphere is a CCN-limited regime, and is thus very susceptible to the influence of DMS. However, atmospheric DMS mixing ratios have only rarely been measured in the summertime Arctic. During July–August 2014, we conducted the first high time resolution (10 Hz DMS mixing ratio measurements for the Eastern Canadian Archipelago and Baffin Bay as one component of the Network on Climate and Aerosols: Addressing Key Uncertainties in Remote Canadian Environments (NETCARE. DMS mixing ratios ranged from below the detection limit of 4 to 1155 pptv (median 186 pptv. A set of transfer velocity parameterizations from the literature coupled with our atmospheric and coincident seawater DMS measurements yielded air-sea DMS flux estimates ranging from 0.02–12 ?mol m?2 d?1, the first published for this region in summer. Airmass trajectory analysis using FLEXPART-WRF and chemical transport modeling using GEOS-Chem indicated that local sources (Lancaster Sound and Baffin Bay were the dominant contributors to the DMS measured along the 21 day ship track, with episodic transport from the Hudson Bay System. After adjusting GEOS-Chem oceanic DMS values in the region to match measurements, GEOS-Chem reproduced the major features of the measured time series, but remained biased low overall (median 67 pptv. We investigated non-marine sources that might contribute to this bias, such as DMS emissions from lakes, biomass burning, melt ponds and coastal tundra. While the local marine sources of DMS dominated overall, our results suggest that non-local and possibly non-marine sources episodically contributed strongly to the observed summertime Arctic DMS mixing ratios.

    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.

  11. Indirect food web interactions: sea otters and kelp forest fishes in the Aleutian archipelago.

    Although trophic cascades-the effect of apex predators on progressively lower trophic level species through top-down forcing-have been demonstrated in diverse ecosystems, the broader potential influences of trophic cascades on other species and ecosystem processes are not well studied. We used the overexploitation, recovery and subsequent collapse of sea otter (Enhydra lutris) populations in the Aleutian archipelago to explore if and how the abundance and diet of kelp forest fishes are influenced by a trophic cascade linking sea otters with sea urchins and fleshy macroalgae. We measured the abundance of sea urchins (biomass density), kelp (numerical density) and fish (Catch per unit effort) at four islands in the mid-1980s (when otters were abundant at two of the islands and rare at the two others) and in 2000 (after otters had become rare at all four islands). Our fish studies focused on rock greenling (Hexagrammos lagocephalus), the numerically dominant species in this region. In the mid-1980s, the two islands with high-density otter populations supported dense kelp forests, relatively few urchins, and abundant rock greenling whereas the opposite pattern (abundant urchins, sparse kelp forests, and relatively few rock greenling) occurred at islands where otters were rare. In the 2000, the abundances of urchins, kelp and greenling were grossly unchanged at islands where otters were initially rare but had shifted to the characteristic pattern of otter-free systems at islands where otters were initially abundant. Significant changes in greenling diet occurred between the mid-1980s and the 2000 although the reasons for these changes were difficult to assess because of strong island-specific effects. Whereas urchin-dominated communities supported more diverse fish assemblages than kelp-dominated communities, this was not a simple effect of the otter-induced trophic cascade because all islands supported more diverse fish assemblages in 2000 than in the mid-1980s.

    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.

    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.

    Full Text Available The Regional Ocean Modeling System (ROMS was used to simulate the Indonesian Archipelago Sea current and temperature with two different vertical mixing schemes. One corresponds to the newly developed K-Profile Parameterization (KPP scheme and the other is adapted from the stability frequency of Brunt-Vaisala Frequency mixing (BVF. It is found that, both of schemes produce reasonably realistic sea surface temperature (SST; however, the root mean square error (RMSE values from the BVF vertical mixing were less than the KPP vertical mixing. The RMSE values from the BVF vertical mixing at northwest and southeast monsoons can be reduced down to 5.1607E-01 0C and 5.7639E-01 0C respectively. These validation results reveal that accuracy of the BVF vertical mixing is better than the KPP vertical mixing.The model results based on the BVF vertical mixing scheme show that the direction of Java Sea, Karimata and Sunda Straits surface current are strongly affected by the zonal wind system. The direction of surface current was change following the monsoonal wind system. On the other hand, the Makasar Strait surface current tend to flow southward throughout the year with annual variations in transport are related dynamically to the monsoon winds. These southward surface currents are known as Indonesian Through Flow (ITF and it is governed by strong pressure gradient from the Pacific to the Indian Oceans. The signals of El Nino 2002 event also can be detected by the model results. It recognized that the strong Equatorial Counter Current flows to eastward to the central part of the Pacific Ocean. The Makasar Strait surface current was stronger than usual but the Karimata Strait surface current was weaker during this period.

    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.

    Ulvalean algae (Chlorophyta) are most commonly described from intertidal and shallow subtidal marine environments worldwide, but are less well known from mesophotic environments. Their morphological simplicity and phenotypic plasticity make accurate species determinations difficult, even at the generic level. Here, we describe the mesophotic Ulvales species composition from 13 locations across 2,300 km of the Hawaiian Archipelago. Twenty-eight representative Ulvales specimens from 64 to 125 m depths were collected using technical diving, submersibles, and remotely operated vehicles. Morphological and molecular characters suggest that mesophotic Ulvales in Hawaiian waters form unique communities comprising four species within the genera Ulva and Umbraulva, each with discrete geographic and/or depth-related distributional patterns. Three genetically distinct taxa are supported by both plastid (rbcL and tufA) and nuclear (ITS1) markers, and are presented here as new species: Umbraulva kaloakulau, Ulva ohiohilulu, and Ulva iliohaha. We also propose a new Umbraulva species (Umbraulva kuaweuweu), which is closely related to subtidal records from New Zealand and Australia, but not formally described. To our knowledge, these are the first marine species descriptions from Hawai'i resulting from the collaboration of traditional Hawaiian nomenclature specialists, cultural practitioners and scientists. The difficulty of finding reliable diagnostic morphological characters for these species reflects a common problem worldwide of achieving accurate identification of ulvalean taxa using solely morphological criteria. Mesophotic Ulvales appear to be distinct from shallow-water populations in Hawai'i, but their degree of similarity to mesophotic floras in other locations in the Pacific remains unknown.

  17. Satellite SST-Based Coral Disease Outbreak Predictions for the Hawaiian Archipelago

    Full Text Available Predicting wildlife disease risk is essential for effective monitoring and management, especially for geographically expansive ecosystems such as coral reefs in the Hawaiian archipelago. Warming ocean temperature has increased coral disease outbreaks contributing to declines in coral cover worldwide. In this study we investigated seasonal effects of thermal stress on the prevalence of the three most widespread coral diseases in Hawai’i: Montipora white syndrome, Porites growth anomalies and Porites tissue loss syndrome. To predict outbreak likelihood we compared disease prevalence from surveys conducted between 2004 and 2015 from 18 Hawaiian Islands and atolls with biotic (e.g., coral density and abiotic (satellite-derived sea surface temperature metrics variables using boosted regression trees. To date, the only coral disease forecast models available were developed for Acropora white syndrome on the Great Barrier Reef (GBR. Given the complexities of disease etiology, differences in host demography and environmental conditions across reef regions, it is important to refine and adapt such models for different diseases and geographic regions of interest. Similar to the Acropora white syndrome models, anomalously warm conditions were important for predicting Montipora white syndrome, possibly due to a relationship between thermal stress and a compromised host immune system. However, coral density and winter conditions were the most important predictors of all three coral diseases in this study, enabling development of a forecasting system that can predict regions of elevated disease risk up to six months before an expected outbreak. Our research indicates satellite-derived systems for forecasting disease outbreaks can be appropriately adapted from the GBR tools and applied for a variety of diseases in a new region. These models can be used to enhance management capacity to prepare for and respond to emerging coral diseases throughout Hawai’i and can be modified for other diseases and regions around the world.

    This study attempts to predict and verify possible spawning aggregation sites and times in the Los Roques Archipelago National Park, Venezuela, based on physical reef characteristics and the knowledge of experienced local fishermen. Three possible aggregation sites were selected for monitoring based on satellite images, low-cost bathymetric mapping and interviews with experienced local fishermen. Abundances and sizes of 18 species that are known to form reproductive aggregations were monitored at these sites using underwater visual census for 7 days after each full moon from February to August, 2007. While spawning events were not observed, possible indirect evidence of spawning aggregations was found for Lutjanus analis at Cayo Sal and Boca de Sebastopol, Lutjanus apodus at Cayo Sal, Lutjanus cyanopterus at Cayo Sal and Piedra La Guasa and Epinephelus guttatus at Bajo California and Cayo de Agua. Additionally, indirect evidence was identified for the past existence of a spawning aggregation of Epinephelus striatus in the northern part of the archipelago, which may have been eliminated by overfishing c.15 years ago. Bathymetric mapping showed that the shelf edge at sites monitored in this study was shallower than at spawning aggregation sites in other parts of the Caribbean, and that sites were not proximal to deep water. While this study does not prove the existence or locations of spawning aggregations of reef fishes in the archipelago, it does add insight to a growing understanding of generalities in the relationship between seafloor characteristics and the locations of transient reef-fish spawning aggregations in the Caribbean.

    Compared to the striking diversification and levels of endemism observed in many terrestrial groups within the Hawaiian Archipelago, marine invertebrates exhibit remarkably lower rates of endemism and diversification. Supralittoral invertebrates restricted to specific coastal patchy habitats, however, have the potential for high levels of allopatric diversification. This is the case of Ligia isopods endemic to the Hawaiian Archipelago, which most likely arose from a rocky supralittoral ancestor that colonized the archipelago via rafting, and diversified into rocky supralittoral and inland lineages. A previous study on populations of this isopod from O'ahu and Kaua'i revealed high levels of allopatric differentiation, and suggested inter-island historical dispersal events have been rare. To gain a better understanding on the diversity and evolution of this group, we expanded prior phylogeographic work by incorporating populations from unsampled main Hawaiian Islands (Maui, Moloka'i, Lana'i, and Hawai'i), increasing the number of gene markers (four mitochondrial and two nuclear genes), and conducting Maximum likelihood and Bayesian phylogenetic analyses. Our study revealed new lineages and expanded the distribution range of several lineages. The phylogeographic patterns of Ligia in the study area are complex, with Hawai'i, O'ahu, and the Maui-Nui islands sharing major lineages, implying multiple inter-island historical dispersal events. In contrast, the oldest and most geographically distant of the major islands (Kaua'i) shares no lineages with the other islands. Our results did not support the monophyly of all the supralittoral lineages (currently grouped into L. hawaiensis), or the monophyly of the terrestrial lineages (currently grouped into L. perkinsi), implying more than one evolutionary transition between coastal and inland forms. Geometric-morphometric analyses of three supralittoral clades revealed significant body shape differences among them. A taxonomic revision of Hawaiian Ligia is warranted. Our results are relevant for the protection of biodiversity found in an environment subject to high pressure from disturbances. PMID:24386463

  20. Surface water quality estimation using remote sensing in the Gulf of Finland and the Finnish Archipelago Sea

    This thesis deals with surface water quality estimation using remote sensing in the Gulf of Finland and the Archipelago Sea. Satellite remote sensing of water and empirical algorithms for surface water quality variables in coastal waters in the Gulf of Finland and the Archipelago Sea are explained and results from the studies in the area are presented. Concurrent in situ surface water measurements, AISA data, Landsat TM data, ERS-2 SAR data, AVHRR and MODIS data were obtained for selected locations in the Gulf of Finland and the Archipelago Sea in August 1997 and from April to May 2000, respectively. The AISA, TM, SAR, AVHRR and MODIS data from locations of water samples were extracted and digital data were examined. Significant correlations were observed between digital data and surface water quality variables. Semi-empirical, simple and multivariate regression analyses, and neural network algorithms were developed and applied in the study area. Application of neural networks appears to yield a superior performance in modelling radiative transfer functions describing the relation between satellite observations and surface water characteristics. The results show that the estimated accuracy for major characteristics of surface waters using the neural network method is much better than retrieval by using regression analysis. Since radar observations of water are strongly affected by surface geometry but not by water quality, radar data should be useful to eliminate the effects of surface roughness from the results when combined with optical observations. However, our results suggest that microwave data improve estimation of water quality very little or not at all. The technique, however, should be examined with new data sets obtained under various weather and water quality conditions in order to estimate its feasibility for estimating surface water quality parameters in the Finnish coastal waters.

    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.

    Full Text Available Qui dit mosquée en Iran dit d’abord un ensemble de moyens ou de facilités laissés au quotidien à la disposition des passants ou des usagers. Ensuite des rituels religieux accomplis, de façon régulière, en présence des autorités ayant le privilège ou le monopole de délivrer un certain savoir islamique. Dans le premier sens la mosquée est un point d’eau, un toit, un accueil où nul(le ne se sentirait exclu(e ou ne se verrait refoulé(e. Dans le second sens elle relève des choix du croyant qui peut préférer un lieu par rapport à un autre, en fonction de critères aussi bien intellectuels que religieux ou encore de type communautaire, professionnel, voire générationnel. C’est sans doute la concomitance même de ces deux formes d’utilité, matérielle et spirituelle, qui font que les mosquées ont résisté, d’une part, au monopole, de l’autre, à l’isolement. Autrement dit, si les mosquées ont servi de cadre à la centralisation de l’Etat, elles ont également été des instances de résistance à la prétention monopolistique de ce dernier. Le présent travail tente une analyse des dynamiques concomitantes, spirituelles et matérielles, qui se renforcent et se complètent, à partir de la nouvelle organisation des mosquées et des nouvelles pratiques qui se déroulent en leur sein ou dans leur proximité. De fait il convient mieux, depuis une vingtaine d’années, de parler de complexes religieux plutôt que de simples lieux de prière.

    Full Text Available We measured depth profiles of underwater PAR (photosynthetically active radiation together with optically derived turbidity and chlorophyll fluorescence values at 11 sampling stations in the South-West Finnish archipelago of the Baltic Sea. The data were collected eight times during the spring, summer and early autumn of 2010. The results illustrate complex and multidimensional variations in the euphotic depth, which was subject to fourfold and twofold differences in the geographical and seasonal dimensions respectively. The spatio-temporal inconsistency and non-linearity of the seasonal euphotic depth variation calls for further studies at different spatial and temporal scales.

    Acropsopilio chilensis Silvestri, 1904 (Eupnoi: Caddidae: Acropsopilioninae), is recorded for Robinson Crusoe Island, Chile. This is the first harvestman species recorded for the Juan Fernández Archipelago and also the first extra-continental record for this species. During the comparison with continental co-specific specimens, some previously unknown, remarkable morphological characteristics were discovered, among them: the absence of ovipositor seminal receptacles and tracheal system, small and probably imperforate spiracles and the presence of a subdistal spiny structure, maybe a stylus, in the major branch of the penis.  PMID:25284403

    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.

    Mesoamerican peoples had a long history of cacao use--spanning more than 34 centuries--as confirmed by previous identification of cacao residues on archaeological pottery from Paso de la Amada on the Pacific Coast and the Olmec site of El Manatí on the Gulf Coast. Until now, comparable evidence from San Lorenzo, the premier Olmec capital, was lacking. The present study of theobromine residues confirms the continuous presence and use of cacao products at San Lorenzo between 1800 and 1000 BCE, and documents assorted vessels forms used in its preparation and consumption. One elite context reveals cacao use as part of a mortuary ritual for sacrificial victims, an event that occurred during the height of San Lorenzo's power. PMID:21555564

    Establishment of conservation priorities for primates is a particular concern in the island archipelagos of Southeast Asia, where rates of habitat destruction are among the highest in the world. Conservation programs require knowledge of taxonomic diversity to ensure success. The Philippine tarsier is a flagship species that promotes environmental awareness and a thriving ecotourism economy in the Philippines. However, assessment of its conservation status has been impeded by taxonomic uncertainty, a paucity of field studies, and a lack of vouchered specimens and genetic samples available for study in biodiversity repositories. Consequently, conservation priorities are unclear. In this study we use mitochondrial and nuclear DNA to empirically infer geographic partitioning of genetic variation and to identify evolutionarily distinct lineages for conservation action. The distribution of Philippine tarsier genetic diversity is neither congruent with expectations based on biogeographical patterns documented in other Philippine vertebrates, nor does it agree with the most recent Philippine tarsier taxonomic arrangement. We identify three principal evolutionary lineages that do not correspond to the currently recognized subspecies, highlight the discovery of a novel cryptic and range-restricted subcenter of genetic variation in an unanticipated part of the archipelago, and identify additional geographically structured genetic variation that should be the focus of future studies and conservation action. Conservation of this flagship species necessitates establishment of protected areas and targeted conservation programs within the range of each genetically distinct variant of the Philippine tarsier.

    Zhoushan Archipelago and the adjacent Xiangshan Harbor are important commercial, tourism, fishing, and mariculture areas. Considering the concern on the effects of anthropogenic activities on the environment, the level and source apportionment of polycyclic aromatic hydrocarbons (PAHs) in surface sediments were investigated. The sum of 16 PAH (?16 PAH) concentrations in the Zhoushan Archipelago ranged from 3.67 to 31.30ngg(-1) d.w., with a mean of 15.01±1.21ngg(-1) d.w., and that in Xiangshan Harbor varied from 11.58 to 481.44ngg(-1) d.w., with a mean of 62.52±32.85ngg(-1) d.w. Diagnostic ratios and factor analysis were performed to identify PAH sources. Results show that PAHs have mixed origins (i.e., traffic-related sources, coal combustion, petrogenic sources, and biomass burning), with pyrolytic-related pollution as the dominant source. This study provided a baseline to promote environmental protection and pollution episode monitoring in the East China Sea. PMID:26563544

    Recent higher-level frog phylogenetic analyses have included a few members of the endemic Philippine frog genus Sanguirana. Although the monophyly of the group has never been disputed, the recent phylogenetically-supported inclusion of the Palawan Wood Frog (Sanguirana sanguinea) in this clade was highly unexpected. In addition, species boundaries and relationships remain unclear and new species continue to be discovered. We estimate the phylogeny for this endemic Philippine genus using two mitochondrial gene regions and six nuclear loci and complete sampling for all known species. We use a time-calibrated Bayesian estimate of phylogeny and model-testing approach to biogeographic inference to infer ancestral areas and probable means of diversification. These analyses identify Sanguirana as an additional clade for which the 'Out-of-Palawan' biogeographic scenario is unambiguously preferred. This study lends additional support to recent work suggesting that a substantial portion of Philippine vertebrate megadiversity originated via colonization of the archipelago from the Palawan microcontinent, with subsequent invasion of oceanic islands (e.g., range expansion over Huxley's Modification of Wallace's Line), numerous instances of overwater dispersal, and geographic radiation across the archipelago.

    Full Text Available This is the first study to explore fish community structure and its relations to habitat and topographic complexity in the shallow coastal waters of the Cyclades Archipelago, North-eastern Mediterranean Sea. In situ visual surveys were carried out at 233 sampling sites in 26 islands of the Cyclades Archipelago. Fish community parameters and biomass were estimated across seven substrate types: sand, seagrass, vertical walls, boulders, horizontal/subhorizontal continuous rock, rocky substrate with patches of sand, and rocky substrate with patches of sand and Posidonia oceanica. Topographic complexity and percentage of algal cover were estimated on hard substrate. Substrate type was found to be a determining factor affecting the structure and composition of fish assemblages. Species number, abundance and biomass were significantly lower in sandy areas and always higher on hard substrates, with seagrass habitats presenting intermediate values. Topographic complexity in rocky bottoms did not seem to affect species richness, density or biomass. This study provides a baseline for future evaluation of changes produced by potential management actions such as the creation of marine protected areas in the study region.

    River discharge can deliver nutrients to the coastal zone and change the hydrologic properties of the water column. Soon after a flash flood from the Yalu River (Northeast China) in August 2010, we investigated the salinity and nutrient concentrations, as well as other environmental conditions in the Changshan Archipelago area, located approximately 100 km west of the river mouth in the northern Yellow Sea. Diluted water was mainly observed in the upper layers shallower than 15 m, with surface salinity between 18.13 and 30.44 in the eastern study area and between 28.16 and 29.72 in the western area. Surface salinity showed a significant negative correlation with concentrations of dissolved nutrients ( P phosphate concentrations were highest in the bottom layer of both areas, with no significant spatial differences. DO varied between 6.06 and 8.25 mg L-1 in the surface layer, and was significantly higher in the eastern area than in the western area in the surface and middle layers. Chl- a concentration was constantly below 4.09 ?g L-1. Our work demonstrated the strong influences of Yalu River on proportions of various nutrient components in the Changshan Archipelago area. Silicic acid and total inorganic nitrogen levels were significantly elevated comparing to phosphate in the eastern area. Such changes can potentially induce phosphate limit to phytoplankton growth.

    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.

    Coral reefs are important because of their high biodiversity and their key role in the tropical marine biosphere. Furthermore, coral reefs are very valuable as a socioeconomic resource as they make important contributions to the gross domestic product of many countries. Thus, it is very important to monitor dynamic spatial distributions of coral reefs and related habitats dominated by coral rubble, dead coral, and bleached corals. Despite these natural and socio-economic advantages, many factors are threatening coral reefs. The study site was selected in Spermonde archipelago, South Sulawesi, Indonesia because this area is included in the Coral Triangle, recognized as the epicenter of coral diversity and a priority for conservation. Images of Landsat MSS, Landsat TM, Landsat ETM, Landsat ETM+, and Landsat 8 data were used to examine changes in the coral reefs of Suranti Island in the Spermonde Archipelago during forty one years from 1972 to 2013. The image processing includes gap fills, atmospheric corrections, geometric corrections, image composites, water column corrections, unsupervised classifications, and reclassifications. Fill Gap processing was done on Landsat ETM+ SLC-off. Subsequently, a multi-component change detection procedure was applied to define changes. Shallow water bottom types classification was divided into live coral, rubble and sand habitats, dead coral with algae, rubble, and sand. Preliminary results showed significant changes during the period 1972-2013 as well as changes in coral reefs, likely explained partly by destructive fishing practices.

    Volcanic rocks were dredged from the Cocos and Fisher ridges and seamounts along a 250 km profile parallel to the Pacific coast of Costa Rica. The composition and laser 40Ar/39Ar ages of the Cocos Ridge and Seamounts are consistent with their formation above the Galápagos hotspot 13.0 14.5 Ma. The reconstructed paleoenvironment and chemistry of the Fisher Ridge are consistent with it having originated at a mid-oceanic ridge system. Laser 40Ar/39Ar dating of fresh basalt glass from the Fisher Ridge yielded isochron ages of 19.2 ± 0.3 Ma and 30.0 ± 0.5 Ma. The Fisher Ridge is along a lithospheric fault that may represent an extensional fracture formed when the oceanic floor rode over the Galápagos hotspot. Even though the younger structures are currently at water depths of >1000 m, volcanological, geochemical, and geophysical observations indicate that they once formed an emerged archipelago very similar in morphology to the Galápagos islands. The diversity of the biota on the isolated Galápagos islands, as first described by Charles Darwin, has had an important influence on the development of the theory of evolution. The existence of a now-drowned Galápagos archipelago 14.5 Ma considerably increases speciation times for the Galápagos biota and provides a complete solution to a long-standing controversy concerning the divergence of the Galápagos marine and land iguanas from a single ancestral species.

    Full Text Available We report recent skeletal remains of squamate reptiles screened from an old garbage dump deposit found on Yoronjima Island, a small island of the Ryukyu Archipelago, in the subtropical northwestern Pacific. Identified remains include at least three species of terrestrial snakes, one sea snake, and seven species of lizards. Among these, the Ryukyu Short-legged Skink, Ateuchosaurus pellopleurus; Kuroiwa’s Leopard Gecko, Goniurosaurus kuroiwae; and one unidentified Gekko species constitute entirely new findings. For a further two snake species and one lizard species, the evidence presented here is the first specimen-based documentation that these species existed on this island, where they are now evidently absent. The present absence of these species on Yoronjima is mainly attributable to predation by the Japanese Weasel, Mustela itatsi, introduced in the mid-1950s. Our results demonstrate a prominent case of recent, sizable deterioration of insular herpetofaunal diversity, which has never been documented with certainty in the Ryukyu Archipelago, and suggest that human influence should be taken into account in biodiversity research in this area.

    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.

    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.

  7. Islas Marias Archipelago, Mexico. A Missing Piece to Reconstruct the Paleoposition of Baja California

    Paleopositions for southern Baja California peninsula have yielded controversial models over the past 30 years. Mainly based on paleomagnetic data many hypotheses place Baja at lower paleolatitudes in front of southern Mexico or Central America with subsequent northward translations. Other models suggest minor, if any, northward displacements with respect to continental Mexico combined with clockwise rotations. Lithological, geochemical, and geochronological similarities for southern Baja California and Puerto Vallarta (western Mexico Pacific margin) igneous rocks seem to confirm the latter model. To further prove this model we have mapped and collected rocks from Maria Madre, the largest island of the Islas Marias archipelago, located in the mouth of the Gulf of California. In an area of only 145 square kilometers, metamorphic basements rocks (ortho and migmatitic gneisses), highly deformed metasediments, granitoids, acid to intermediate volcanic sequences, and a cover with gently folded marine sediments are exposed. The basement complex with gneisses and metasediments, including garnet-bearing paragneiss and calc silicates, as well as the granodioritic-tonalitic intrusives display an extraordinary accordance with similar units observed in the Los Cabos Block (LCB) of Baja California Sur. Furthermore, U-Pb zircon ages of 162 and 170 Ma for the basement gneisses and of 80 Ma for the granitoids have been reported also from the LCB. Additionally, upper Cretaceous intrusive ages are well known from the Puerto Vallarta batholith in Jalisco and Nayarit, mainland Mexico. Geochemical and isotopic data as well as Nd model ages confirm a magmatic consanguinity of LCB, Islas Marias, and Puerto Vallarta granitoids. The volcanic units of Maria Madre Island include ignimbrites and effusive dacitic-rhyolithic rocks, which can be correlated to the Sierra Madre Occidental province and the Comundú Formation of Baja California. Age determinations are under work to confirm this hypothesis. Finally, the sedimentary cover record several subsidence and uplift events, possibly related to the opening of the Gulf of California. Micropaleontological investigations on Neogene deposits give evidence for an above sea level position of the islands since the late Pleistocene. In summary, our new lithological, geochemical, and geochronological investigations on the Isla María Madre rock suite confirm a common magmatic arc parenthood of these units with respect to mainland Mexico at latitudes of Puerto Vallarta and with the LCB of Baja California Sur. Large paleolatitudal displacements of Baja can be discarded from these results.

    A representative set of 30 lakes from the Azores archipelago (Portugal) has been studied to obtain data on their volcanic setting and water geochemistry. The majority of the studied lakes are located inside volcanic craters and subsidence calderas, while the remaining lakes are located in topographic depressions not associated with volcanic centres, in depressions of tectonic origin and inside lava caves. In general, the Azorean volcanic lakes are small, with surface areas between 8.94 × 10 - 4 km 2 and 4.35 km 2 and volumes between 2.4 × 10 3 and 4.78 × 10 7 m 3; median = 3.99 × 10 4 m 3, presenting maximum depths between 0.8 and 33 m. Mostly of the Na-Cl to Na-HCO 3 type, the lake waters are generally low temperature (11.9-24.6 °C), very dilute (TDS range between 11.0 and 356.2 mg/L; median = 36.8 mg/L) and a clear exception is Furna do Enxofre lake (Graciosa island) that shows a Mg trend. Two types of lake waters can be recognized: 1) one is characterized by Na/Cl ratio close to the seawater value and have evolved, and evolve by marine contribution; and 2) Na-HCO 3 type waters that, in addition to sea-salt input, have been influenced by other processes (e.g., water-rock interaction, hydrothermal seepage into the lake bottom) evident from higher total CO 2 content (365.1 mg/L) and SiO 2 content (74.9 mg/L), as well demonstrated by in the Furna do Enxofre lake. Nevertheless, volcanic contribution cannot be excluded for some lakes as Furna do Enxofre. Vertical profiles made at the deepest lakes of São Miguel reveal that major-ion content varies little with depth, largely independent of the occurrence of thermally driven density stratification in summer for some lakes. However, dissolved CO 2 increases with depth and is kept in the hypolimnion in summer, whereas the HCO 3- content is stable, suggesting that CO 2 release exceeds acidity neutralization by water-rock interaction. During winter, without stratification, the dissolved CO 2 increase is less sharp for the majority of the lakes, with the exception of Furnas and Furna do Enxofre lakes. The CO 2 enrichment observed for certain lakes (e.g., Furna do Enxofre and Furnas) implies a volcanic input. Moreover, as these lakes themselves are located near hydrothermal surface manifestations, they therefore offer good targets of volcano monitoring in the Azores.

    Spatial and temporal variability of the island mass effect (IME; defined as local increases of phytoplankton associated with the presence of islands) at the Juan Fernández Archipelago (JFA) is analyzed using chlorophyll-a (Chl-a) satellite data, altimetry, sea surface temperature, wind, geostrophic currents and net heat flux over a ten year period (2002-2012). The the JFA islands (Robinson Crusoe-Santa Clara (RC-SC) and Alejandro Selkirk (AS)) present wakes with significant Chl-a increases, mainly during spring time. These wakes can reach Chl-a values of one order of magnitude higher (~1 mg m-3) than the surrounding oligotrophic waters (<0.1 mg m-3). The wakes are similar to von Kármán vortex streets which have been used to explain the impact of IME on Chl-a increases in numerical models. The wakes are formed from a high productivity area in the lee of the island, extending to the oceanic region as high Chl-a patches associated with submesoscale eddies that are detached from the islands and connected by less-productive zones. This pattern coincides with previous models that predict the effects of island-generated flow perturbations on biological production variability. The IME is a recurrent feature of islands that has even been observed in decadal average fields. In such average fields, the Chl-a values in RC-SC and AS islands can exceed values found in a Control Zone (a zone without islands) by ~50% and 30%, respectively. Seasonal and interannual variability reveals that, as a consequence of the IME, the winter Chl-a maximum associated with the development of winter convection and mesoscale eddies that propagate from the continental zone, promote that the Chl-a maximum extends towards spring. The IME has an impact on the island on both a local as well as a more regional scale that affects an area of ~40,000 km2 (1°Latitude×4°Longitude) centered on the islands. The transport of high productivity patches associated with submesoscale eddies may be responsible for IME propagation at a regional scale. Around the islands, the presence of a weak oceanic incident flow and strong and recurrent wind-wakes, suggest that the generation of Chl-a wakes result from a combined effect between both forcings.

  11. Radium 228 distribution and mixing in San Nicolas and San Pedro Basins, southern California borderland

    International Nuclear Information System (INIS)

    Sediment profiles of 228Ra and 232Th and water column profiles of 228Ra are presented for San Nicolas and San Pedro Basins, located in the Southern California Borderland. These data are used to estimate fluxes of 228Ra from the sediments, the vertical eddy diffusivity (Kz) in the water column, and the upwelling velocity (wz). The fluxes of 228Ra from sediments, estimated by integrating the downcore deficiency of 228Ra with respect to its parent nuclide 232Th, are 335 ± 115 atoms/m2s for San Nicolas Basin and 166 ± 50 atom/m2s for San Pedro Basin. San Nicolas Basin sediments have an excess of 228Ra in the upper 4 cm, but irrigation and diffusion create a 228Ra deficiency from 4 to 30 cm. San Pedro Basin sediments are anoxic and laminated, have a 228Ra deficiency above 6-12 cm depth, and have no surface excess of 228Ra. Basin waters appear to be well-mixed horizontally below sill depth and in steady-state with respect to 228Ra. Concentrations of 228Ra increase from sill depth to the bottom, ranging from approximately 1.0 dpm/100 kg to 2.4 dpm/100 kg in San Nicolas Basin and from 1.6 dpm/100 kg to 3.1 dpm/100 kg in San Pedro Basin. Estimates of Kz and wz at several horizons in these basins are made by evaluating two steady state mass balance equations, one for 228Ra and one for heat. Upper limits for Kz are 23 cm2/s at 1,700 m in San Nicolas and 2.8 cm2/s at 850 m in San Pedro Basin. The best estimate for Kz and wz for the deeper part of the basins are: Kz = 5-17 cm2/s and wz = 50-150 m/y in San Nicolas Basin, and Kz = 1-3 cm2/s and wz = 20-50 m/y in San Pedro Basin

  13. Crustal structure beneath the Galápagos Archipelago from ambient noise tomography and its implications for plume-lithosphere interactions (Invited)

    2010-12-01

    To constrain the seismic structure of the crust beneath the Galápagos hotspot we conducted a tomography study using high-frequency Rayleigh waves recovered from cross-correlations of ambient noise. Data are from 10 broadband stations deployed over a period of 3 years plus one station of the Global Seismographic Network. The seismic network spanned an area of 200 by 300 km2 and had a station spacing of 50-70 km. We used cross-correlations of continuous vertical seismic records for 24 time periods that range from 11 to 50 days in duration. We measured Rayleigh-wave group velocities from the stacked cross-correlation signal of all time periods for each of 55 station pairs at frequencies between 0.1 and 0.33 Hz. Such waves, after accounting for the effect of water depth, are sensitive to shear wave velocity VS structure between 3 and 13 km depth. Crustal VS is up to 25% lower than that of very young crust at the East Pacific Rise (EPR) and is comparable to that of Hawaii. We attribute the lower-than-normal velocities to heating by increased intrusive activity above the Galápagos plume and the construction of a highly porous volcanic platform emplaced on top of the pre-existing crust. Crustal VS beneath the western archipelago is up to 15% lower than beneath the eastern archipelago at 3-8 km depth and up to 8% lower at 8-13 km depth. The west-to-east increase in VS appears to be gradual and correlates with distance downstream from the hotspot. We attribute the velocity increase to cooling of the crust after its passage above the Galápagos plume and to a gradual decrease in porosity in the extrusive layer. On the basis of our results, which constrain the broad-scale thermal and chemical structure of the crust and lithosphere, as well as a synthesis of recent plate reconstructions and gravity data, we suggest that the age of the lithosphere at the time of loading and its thickness and internal structure play major roles in shaping the location of hotspot volcanism and the morphology of volcanic landforms in the Galápagos Archipelago. For instance, variations in the flexural response to loading, which are correlated with volcano size and morphology, cannot be explained by the current thermal state of the lithosphere and thus represent varying elastic strength at the time of loading. In addition, we propose that some of the northwest- and northeast-trending Darwinian lineaments that are found throughout the archipelago are associated with pre-existing variations in lithospheric strength caused by past episodes of ridge jumping and ridge propagation. These zones of weakness are likely reactivated by stresses resulting from plume-lithosphere interactions. Moment tensor solutions for several near-archipelago earthquakes are consistent with reactivation of these lineaments.
