    Holocene relative sea-level (RSL) records from far-field locations are important for understanding the driving mechanisms controlling the nature and timing of the mid-late Holocene reduction in global meltwaters and providing background rates of late Holocene RSL change with which to compare the magnitude of 20th century RSL rise. The Caribbean region has traditionally been considered far-field (i.e., with negligible glacio-isostatic adjustment (GIA) influence), although recent investigations indicate otherwise. Here, we consider the spatial variability in glacio-isostatic, tectonic and local contributions on RSL records from the circum-Caribbean region to infer a Holocene eustatic sea-level signal. We have constructed a database of quality-controlled, spatially comprehensive, Holocene RSL observations for the circum-Caribbean region. The database contains over 500 index points, which locate the position of RSL in time and space. The database incorporates sea-level observations from a latitudinal range of 5°N to 25°N and longitudinal range of 55°W to 90°W. We include sea-level observations from 11 ka BP to present, although the majority of the index points in the database are younger than 8 ka BP. The database is sub-divided into 13 regions based on the distance from the former Laurentide Ice Sheet and regional tectonic setting. The index points were primarily derived from mangrove peat deposits, which in the Caribbean form in the upper half of the tidal range, and corals (predominantly Acropora palmata), the growth of which is constrained to the upper 5 m of water depth. The index points are classified on the basis of their susceptibility to compaction (e.g., intercalated, basal). The influence of temporal changes in tidal range on index points is also considered. The sea-level reconstructions demonstrate that RSL did not exceed the present height (0 m) during the Holocene in the majority of locations, except at sites in Suriname/Guayana and possibly Trinidad

    In 2011 and 2015, the nations of the Caribbean Sea were overwhelmed by the unprecedented quantity of Sargassum that washed ashore. This issue prompted international discussion to better understand the origins, distribution, and movement of Sargassum, a free-floating brown macro alga with ecological, environmental, and commercial importance. In the open ocean, Sargassum mats serve a vital ecological function. However, when large quantities appear onshore without warning, Sargassum threatens local tourist industries and nearshore ecosystems within the Caribbean. As part of the international response, this project investigated the proliferation of this macro alga within the Caribbean Sea from 2003-2015, and used NASA Earth observations to detect and model Sargassum growth across the region. The Caribbean Oceans team calculated the Floating Algal Index (FAI) using Terra Moderate Resolution Imaging Spectroradiometer (MODIS) data, and compared the FAI to various oceanic variables to determine the ideal pelagic environment for Sargassum growth. The project also examined the annual spread of Sargassum throughout the region by using Earth Trends Modeler (ETM) in Clark Labs' TerrSet software. As part of the international effort to better understand the life cycle of Sargassum in the Caribbean, the results of this project will help local economies promote sustainable management practices in the region.

    In 1976, IOC-UNESCO and UNEP convened a meeting in Port of Spain to analyze the marine pollution problems in the region, noting that petroleum pollution was of regionwide concern and recommended initiating a research and monitoring program to determine the severity of the problem and monitor its effects. The Wider Caribbean is potentially one of the largest oil-producing areas in the world. Major production sites include Louisiana and Texas in the U.S.; the Bay of Campeche, Mexico; Lake Maracaibo, Venezuela; and the Gulf of Paria, Trinidad. All these are classified as high-risk production accident zones. Main sources of petroleum pollution in the Wider Caribbean are production, exploitation, transportation, urban and municipal discharges, refining and chemical wastes, normal loading and unloading operations, and accidental spills. About 5 million barrels of crude oil are transported daily in the Caribbean, thus generating an intense tanker traffic. It has been estimated that oil discharges from tank washings within the Wider Caribbean could be as high as 7 million barrels/yr. The results of the Caribbean Pollution Regional Program (CARIPOL) conducted between 1980 and 1987 pointed out that significant levels of petroleum pollution exist throughout the Wider Caribbean, including serious tar contamination of windward exposed beaches, high levels of floating tar within the major current systems, and very high levels of dissolved and dispersed hydrocarbons in surface waters. Major adverse effects of this type of pollution include: high tar levels on many beaches that either prevent their recreational use or require very expensive cleanup operations, distress and death for marine life, and responses in the enzyme systems of marine organisms that have been correlated with declines in reproductive success. Finally, the presence of polycyclic aromatic hydrocarbons (PAHs) in tissues of important economic species has been reported, creating a risk for public health because of

    The distribution of oil degrading bacteria (ODB) and its ratios to viable heterotrophic bacteria (CFU) and direct counts (AODC) were examined in relation to the surface currents of the western Caribbean Sea. High ODB/CFU and ODB/AODC ratios were found, suggesting that chronic sources of hydrocarbons in the region may have a larger impact than those in the southern Gulf of Mexico, where previous studies have been performed. It was concluded that, in western Caribbean waters, the distribution of oil degrading bacteria, or its ratios to CFU or AODC, could be useful indicators of chronic oil inputs originating at the east of the Caribbean Sea, as well as their motions afterwards.

    2007-01-01

    Aim The long-term stability of coastal ecosystems such as mangroves and salt marshes depends upon the maintenance of soil elevations within the intertidal habitat as sea level changes. We examined the rates and processes of peat formation by mangroves of the Caribbean Region to better understand biological controls on habitat stability. Location Mangrove-dominated islands on the Caribbean coasts of Belize, Honduras and Panama were selected as study sites. Methods Biological processes controlling mangrove peat formation were manipulated (in Belize) by the addition of nutrients (nitrogen or phosphorus) to Rhizophora mangle (red mangrove), and the effects on the dynamics of soil elevation were determined over a 3-year period using rod surface elevation tables (RSET) and marker horizons. Peat composition and geological accretion rates were determined at all sites using radiocarbon-dated cores. Results The addition of nutrients to mangroves caused significant changes in rates of mangrove root accumulation, which influenced both the rate and direction of change in elevation. Areas with low root input lost elevation and those with high rates gained elevation. These findings were consistent with peat analyses at multiple Caribbean sites showing that deposits (up to 10 m in depth) were composed primarily of mangrove root matter. Comparison of radiocarbon-dated cores at the study sites with a sea-level curve for the western Atlantic indicated a tight coupling between peat building in Caribbean mangroves and sea-level rise over the Holocene. Main conclusions Mangroves common to the Caribbean region have adjusted to changing sea level mainly through subsurface accumulation of refractory mangrove roots. Without root and other organic inputs, submergence of these tidal forests is inevitable due to peat decomposition, physical compaction and eustatic sea-level rise. These findings have relevance for predicting the effects of sea-level rise and biophysical processes on tropical

    Hermit crabs represent the marine life in the Colombian Caribbean, and are important for the dynamic equilibrium maintenance in ecosystems, the ecological interactions and their impact on food web stability. Generally, in order to come up with some conservation strategies, strong bio-geographical information is needed for poll cies definition. With this aim, this study analyzed the distribution patterns of hermit crabs in the Colombian Caribbean Sea. through classification and spatial ordination multivariate analyses, using historical records from years 1916 to 2006. Besides, the world distribution of Colombian species and their geographic affinity in the Caribbean and Western Atlantic were identified. The results show deep differences between coastal and continental slope faunas, and latitudinal differences in the assemblages, with the identification of three groups: Northeast. Center and Southwest. The differences in faunal composition that support these three groups were determined. Based on maps of the Colombian marine ecosystems, it was found that the main factors affecting the distribution of hermit crabs were the Caribaná slope (depth), water-mass temperature, Guajira sea-grass beds, and particular conditions of "Coralline Archipelagos" and "Darién" eco-regions. Colombian hermit crab fauna is more related to the North Atlantic and the Antilles, than to the South Atlantic and the Gulf of Mexico. Additionally, geographical sub-provinces in which Colombia is included, these were found as transition zones among Northern and Austral subprovinces of the Greater Caribbean.

    For the first time in the southern Caribbean Sea Margin of Colombia (between 450 - 700 m deep) we confirm the presence of methane seep communities near the deltas of the Magdalena and Sinu rivers. Some evidences of the occurrence of those communities include: i) bivalves constituents of marine chemosynthesis-based communities, which are indicators of reducing environments as vesicomyid and lucinid bivalves (Vesicomya caribbea, Calyptogena ponderosa, Ectenagena modioliforma, Lucinoma spp. and Graecina colombiensis), together with the rare solemyid clam Acharax caribbaea, ii) other seep-associated fauna such as the trochid snail Cataegis meroglypta, iii) the first report of vestimentiferan tubeworms for the area and, iv) the presence of authigenic carbonates; these constructions form hard substrates colonized by sessile fauna. Additionally, more than 20 species of benthic non-seep fauna were found associated in the area. The collected fauna exhibits an elevated taxonomic similarity to other modern and fossil seep communities from the Caribbean (Barbados Prism, Gulf of Mexico, Cenozoic seep taxa from Barbados, Trinidad and Venezuela). The presence of these chemosymbiotic species seems to be related to mud diapirism activity in the South West of the Colombian coast, this geologic characteristic indicates tectonic and depositional processes associated with the aforementioned deltas. Further research is necessary to establish biological and geological interactions, geochemical and geophysical controls, and organization of cold seeps communities in this unexplored area of the Caribbean.

    Planktonic foraminifera are widely used for paleoceanographic reconstructions of different water mass dynamics. For accurate reconstruction, it is crucial to understand the habitat, ecology and shell chemistry of single species. In this study, living planktonic foraminifera were collected with a multi closing net in the Caribbean Sea during R/V Meteor cruises M78/1 in 2009, and M94, M95 in 2013 respectively. The population structure in surface to subsurface waters was assessed and related to salinity, temperature and chlorophyll concentrations. Stable isotopes and trace elements of shell calcite are measured to improve the proxy calibration. At all stations, the highest standing stock was observed in the near-surface layer and the highest population densities in the eastern Caribbean Sea. Markedly low abundances of foraminifera were recognized in Gulf of Paria and close to the Orinoco River plume. The most frequent species in the Caribbean were Globigerinoides sacculifer, Globigerinita glutinata, Globigerinoides ruber, Globigerinella calida, and Neogloboquadrina dutertrei. Abundance maxima of G. sacculifer and G. ruber were always recorded in the surface water. The preferred habitat of N. dutertrei was the near-surface mixed layer, even though the species has been commonly referred to calcify in the thermocline. As expected, the deep dweller Globorotalia truncatulinoides (dextral) was mainly observed in upper intermediate waters, although juvenile specimens were found at shallower depths. Plankton tow data showed that shallow-living species adjusted their habitat to surface water masses, which deepened in the southern Caribbean Sea from East to West. Furthermore, intermediate to deep dwellers appear to prevail in surface or subsurface waters during the early stage of their life cycle.

    North Atlantic Oscillation; more (less) WT 2 and less (more) WT 8 than usually occur from January to early April during warm (cold) ENSO events, the strongest anomalies being recorded during eastern events. Multinomial logistic regression is used to hindcast the 11-day low-pass filtered occurrence of WTs from local (Caribbean Sea and Gulf of Mexico) and remote (Eastern and Central Tropical Pacific) sea surface temperatures (SSTs). In boreal summer, the interannual variability of the seasonal occurrence of WTs 4-6 is well hindcast when at least the Caribbean Sea and Eastern Tropical Pacific are included as predictors with anomalously warm (cold) SSTs over the Caribbean Sea (Eastern Tropical Pacific) being related to more WT 5-6 and less WT 4 and vice-versa. Using antecedent SST to forecast WT frequency shows that the SST forcing is negligible at the start of boreal summer and increases toward its end.

  16. Phylogenetic diversity and community structure of sponge-associated bacteria from mangroves of the Caribbean Sea

    2011-02-08

    To gain insight into the species richness and phylogeny of the microbial communities associated with sponges in mangroves, we performed an extensive phylogenetic analysis, based on terminal restriction fragment length polymorphism profiling and 16S ribosomal RNA gene sequences, of the 4 sponge species Aplysina fulva, Haliclona hogarthi, Tedania ignis and Ircinia strobilina as well as of ambient seawater. The sponge-associated bacterial communities contained 13 phyla, including Poribacteria and an unclassified group not found in the ambient seawater community, 98% of which comprised Proteobacteria, Cyanobacteria and Bacteroidetes. Although the sponges themselves were phylogenetically distant and bacterial community variation within the host species was observed, microbial phyla such as Proteobacteria, Acidobacteria, Chloroflexi and the unclassified group were consistently observed as the dominant populations within the communities. The sponge-associated bacterial communities resident in the Caribbean Sea mangroves are phylogenetically similar but significantly distinct from communities found in other biogeographical sites such as the deep-water environments of the Caribbean Sea, the South China Sea and Australia. The interspecific variation within the host species and the distinct biogeographical characteristics that the sponge-associated bacteria exhibited indicate that the acquisition, establishment and formation of functional sponge-associated bacterial communities may initially be the product of both vertical and horizontal transmission, and is then shaped by the internal environment created by the sponge species and certain external environmental factors. © Inter-Research 2011.

    Data from five cruises during 1985-1986 along 63.55°W, across the eastern Caribbean Sea, are examined for seasonal variability of gcostrophic transport. A biannual maximum transport signal appears to correspond to that measured in the Florida Straits as well as to variations in the regional wind stress curl. Similar seasonal variations in the properties of water masses, entering the eastern margin of the basin and concentrated through the passages of the Lesser Antilles, are also indicated. A permanent system of strong westward flowing streams, interspersed by weaker eastward flowing streams, is shown to exist.

    An almost ubiquitous occurrence of imposex and butyltins in the molluscs from US Virgin Islands gives evidence to a widespread contamination with the antifouling agent tributyltin (TBT), which most likely is related to a relatively intense ship traffic. Three different muricid neogastropod species...... Thais deltoidea, Thais rustica and Purpura patula all seem to have potential as suitable and sensitive bioindicators for assessing levels and effects of TBT pollution in coastal areas including coral reefs in the Caribbean Sea.

    La Guajira Peninsula lies within a large upwelling system along the South Caribbean Coast, created by the NE trade winds. In this location, sea surface temperature (SST) exhibits the lowest mean value and the highest variability in the whole Colombian Basin. The seasonal variation of SST explains up to 75 % of the total variability. La Guajira coastal zone also experiences the highest values of wind stress and wind stress curl, with the greatest annual and semiannual variability in the Colombian Basin. It has been shown that wind stress curl enhances the upwelling over the region. Near 90% of the variability of SST in La Guajira can be explained by the seasonality plus the first three EOFs interannual modes: the first, synchronous throughout the Basin, is dominant, and consists of a uniform interannual variation in phase with the North Tropical Atlantic Index; the second co-varies strongly with the second mode of wind stress curl; and the third reflects the role of the vertical atmospheric circulation cell associated with the Caribbean Low Level Jet off Central America. The inclusion of wind stress curl with its maximum offshore of La Guajira explains in part the extension of cool coastal water into the Colombian Basin, with advection in filaments, eddies and meanders. In order to complement the physical knowledge of La Guajira upwelling system, an analysis of water masses, sea surface height, Ekman suction, Ekman transport and coastal upwelling index (CUI) was performed. Hydrographic data was obtained from gridded climatologies from the National Oceanographic Data Center (WOD01); sea surface height anomalies from the Archiving, Validation, and Interpretation of Satellite Oceanography (AVISO) data; and wind data from the Cross-Calibrated Multi-Platform Ocean Surface Wind Velocity Product for Meteorological and Oceanographic Applications (CCMP). The upwelling forms a local water mass, La Guajira surface water (LGSW), with the mixing of subtropical underwater and

    Full Text Available Phylogeographic studies have provided valuable insights into the evolutionary histories and biodiversity of different groups in the Caribbean, a region that harbors exceptional terrestrial and marine biodiversity. Herein, we examined phylogeographic patterns of the poorly dispersing supralittoral isopod Ligia sampled from 35 localities in the Caribbean Sea and adjacent areas, as well as from Veracruz (Gulf of Mexico, the type locality of L. baudiniana (the only currently recognized native Ligia species in the Caribbean. We conducted Maximum Likelihood and Bayesian phylogenetic analyses of four mitochondrial genes (Cytb, 16S rDNA, 12S rDNA and COI and Parsimony analyses of one nuclear gene (NaK. We found a well-supported and highly divergent clade of Ligia that is distributed in the Caribbean Sea, Bahamas, southern Florida, Bermuda, and the Pacific coast of Central America and Colombia, but not in the Gulf of Mexico. A characteristic appendix masculina distinguishes this clade from other lineages of Ligia. Large divergences within this clade suggest that it constitutes a cryptic species complex. Genetically and morphologically, the specimens from the type locality of L. baudiniana were indistinguishable from the non-native species L. exotica. Some phylogeographic patterns of Ligia in the study area may be consistent with the proto-Antillean or GAARlandia vicariant hypotheses, but uncertainty concerning divergence times and aspects of the geological history precludes stronger biogeographical inferences. Passive overwater dispersal appears to have played an important role in shaping phylogeographic patterns of Ligia in the Caribbean Sea. These patterns, however, do not correspond with predicted biogeographic patterns based on population connectivity of marine organisms with larval dispersal, and do not reflect the southeast to northwest colonization pattern that has been proposed for the colonization of the Caribbean from South America by some

  3. Giant submarine landslides on the Colombian margin and tsunami risk in the Caribbean Sea

    Leslie, Stephen C.; Mann, Paul

    2016-09-01

    A series of three giant, previously unrecognized submarine landslides are defined on a 16,000 line km grid of multi-channel 2D seismic reflection profiles along the active margin of northern Colombia in the western Caribbean Sea. These deposits record the collapse and mobilization of immense segments (thousands of cubic kilometers) of the submarine slope and are comparable in scale to the largest known landslides on Earth. We show that the breakaway zone for these events corresponds to the tectonically over-steepened slopes of the Magdalena Fan, an extensive submarine fan composed of sediments sourced from the northern Andes and deposited by the Magdalena River. An over-pressured zone of weakness at the base of the gas-hydrate stability layer within the fan likely facilitates slope failure. Timing of these massive slope failures is constrained by well control and occurred from the mid-to-late Pliocene to mid-Pleistocene. To understand the tsunamigenic hazards posed by the recurrence of such an event today, we model the potential tsunami source created by a submarine landslide of comparable thickness (400 m) and lateral extent (1700 km2) derived from the over-steepened upper slopes of the present day Magdalena Fan. Our modeling indicates the recurrence of an analogous slope failure would result in a major tsunami that would impact population centers along the Caribbean coastlines of Colombia, Central America, and the Greater Antilles with little advance warning.

    2014-09-01

    Elevated sea surface temperature (SST) caused by global warming is one of the major threats to coral reefs. While increased SST has been shown to negatively affect the health of coral reefs by increasing rates of coral bleaching, how changes to atmospheric heating impact SST distributions, modified by local flow environments, has been less understood. This study aimed to simulate future water flow patterns and water surface heating in response to increased air temperature within a coral reef system in Bocas del Toro, Panama, located within the Caribbean Sea. Water flow and SST were modeled using the Delft3D-FLOWcomputer simulation package. Locally measured physical parameters, including bathymetry, astronomic tidal forcing, and coral habitat distribution were input into the model and water flow, and SST was simulated over a four-month period under present day, as well as projected warming scenarios in 2020s, 2050s, and 2080s. Changes in SST, and hence the thermal stress to corals, were quantified by degree heating weeks. Results showed that present-day reported bleaching sites were consistent with localized regions of continuous high SST. Regions with highest SST were located within shallow coastal sites adjacent to the mainland or within the interior of the bay, and characterized by low currents with high water retention times. Under projected increases in SSTs, shallow reef areas in low flow regions were found to be hot spots for future bleaching.

  6. Pteropods from the Caribbean Sea: dissolution as an indicator of past ocean acidification

    2011-07-01

    Full Text Available The aragonite shell–bearing thecosome pteropods are an important component of the oceanic plankton. However, with increasing pCO2 and the associated reduction in oceanic pH (ocean acidification, thecosome pteropods are thought to be particularly vulnerable to shell dissolution. The distribution and preservation of pteropods over the last 250,000 years have been investigated in marine sediment cores from the Caribbean Sea close to the island of Montserrat. Using the Limacina Dissolution Index (LDX, fluctuations in pteropod dissolution through the most recent glacial/interglacial cycles is documented. By comparison to the oxygen isotope record (global sea ice volume, we show that pteropod dissolution is closely linked to global changes in pCO2 and pH and is, therefore, a global signal. These data are in agreement with the findings of experiments upon living pteropods, which show that variations in pH can greatly affect aragonitic shells. The results of this study provide information which may be useful in the prediction of future changes to the pteropod assemblage caused by ocean acidification.

The aggregation remains in the nutrient-rich waters off Isla Holbox, Isla Contoy and Isla Mujeres, Quintana Roo for several months in the summer and then dissipates between August and October. Little has been known about where these sharks come from or migrate to after they disperse. From 2003-2012, we used conventi...

    Large quantities of African dust are carried across the North Atlantic toward the Caribbean every summer by Trade Winds. Atmospheric deposition of dust aerosols, and in particular wet deposition, is widely acknowledged to be the major delivery pathway for nutrients to ocean ecosystems, as iron, phosphorus and various nitrogen species. The deposition of this dustis so known to have an important impact on biogeochemical processes in the Tropical and Western Atlantic Ocean and Caribbean including Puerto-Rico. However, very few data exists on the chemical composition in nutrients in dusty rain in this region. In the framework of the Dust-ATTAcK project, rainwater was collected at the natural reserve of Cape San Juan (CSJ) (18.38°N, 65.62°W) in Puerto-Ricobetween 20 June 2012 and 12 July 2012 during thedusty period. A total of 7 rainwater events were sampled during various dust plumes. Complementary chemical analyses on aerosols in suspension was also determined during the campaign. The results on dust composition showed that no mixing with anthropogenic material was observed, confirming dust aerosols were the major particles incorporated in rain samples. The partitioning between soluble and particulate nutrients in rain samples showed that phosphorous solubility ranged from 30 and 80%. The average Fe solubility was around 0.5%, in agreement with Fe solubility observed in rains collected in Niger during African monsoon. That means that the high solubility measurements previously observed in Caribbean was probably due to an anthropogenic influence. Atmospheric wet deposition fluxes of soluble and total nutrients (N, P, Si, Fe, Co, Cu, Mn, Ni, Zn) to Caribbean Sea were determined. Atmospheric P and N inputs were strongly depleted relative to the stoichiometry of phytoplankton Fe, N, P and Si requirements.The nitrogen speciation was also determined and showed the predominance of ammonium form. 3-D modeling was used to estimate the spatial extend of these fluxes over the

    Full Text Available Whale sharks, Rhincodon typus, are often perceived as solitary behemoths that live and feed in the open ocean. To the contrary, evidence is accumulating that they are gregarious and form seasonal aggregations in some coastal waters. One such aggregation occurs annually north of Cabo Catoche, off Isla Holbox on the Yucatán Peninsula of Mexico. Here we report a second, much denser aggregation of whale sharks (dubbed "the Afuera" that occurs east of the tip of the Yucatán Peninsula in the Caribbean Sea. The 2009 Afuera event comprised the largest aggregation of whale sharks ever reported, with up to 420 whale sharks observed in a single aerial survey, all gathered in an elliptical patch of ocean approximately 18 km(2. Plankton studies indicated that the sharks were feeding on dense homogenous patches of fish eggs, which DNA barcoding analysis identified as belonging to little tunny, Euthynnus alletteratus. This contrasts with the annual Cabo Catoche aggregation nearby, where prey consists mostly of copepods and sergestid shrimp. Increased sightings at the Afuera coincide with decreased sightings at Cabo Catoche, and both groups have the same sex ratio, implying that the same animals are likely involved in both aggregations; tagging data support this idea. With two whale shark aggregation areas, high coastal productivity and a previously-unknown scombrid spawning ground, the northeastern Yucatán marine region is a critical habitat that deserves more concerted conservation efforts.

    Full Text Available Abstract Biofilm has a primary role in the pathogenesis of diseases and in the attachment of multicellular organisms to a fouled surface. Because of that, the control of bacterial biofilms has been identified as an important target. In the present study, five lipid compounds isolated from soft coral Eunicea sp. and three terpenoids together with a mixture of sterols from Eunicea fusca collected at the Colombian Caribbean Sea showed different effectiveness against biofilm formation by three marine bacteria associated with immersed fouled surfaces, Ochrobactrum pseudogringnonense,Alteromona macleodii and Vibrio harveyi, and against two known biofilm forming bacteria, Pseudomonas aeruginosa ATCC 27853 and Staphylococcus aureus ATCC 25923. The pure compounds were characterized by NMR, HRESI-MS, HRGC-MS and optical rotation. The most effective compounds were batyl alcohol (1 and fuscoside E peracetate (6, acting against four strains without affecting their microbial growth. Compound 1 showed biofilm inhibition greater than 30% against A. macleodii, and up to 60% against O. pseudogringnonense,V. harveyi and S. aureus. Compound 6 inhibited O. pseudogringnonense and V. harveyi between 25 and 50%, and P. aeruginosa or S. aureus up to 60% at 0.5 mg/ml. The results suggest that these compounds exhibit specific biofilm inhibition with lower antimicrobial effect against the bacterial species assayed.

    The monthly averaged freshwater discharge data from ten rivers in northern Colombia (Caribbean alluvial plain) draining into the Caribbean Sea were analysed to quantify the magnitudes, to estimate long-term trends, and to evaluate the variability of discharge patterns. These rivers deliver ∼340.9 km3 yr-1 of freshwater to the Caribbean Sea. The largest freshwater supply is provided by the Magdalena River, with a mean discharge of 205.1 km3 yr-1 at Calamar, which is 26% of the total fluvial discharge into this basin. From 2000 to 2010, the annual streamflow of these rivers increased as high as 65%, and upward trends in statistical significance were found for the Mulatos, Canal del Dique, Magdalena, and Fundación Rivers. The concurrence of major oscillation processes and the maximum power of the 3-7 year band fluctuation defined a period of intense hydrological activity from approximately 1998-2002. The wavelet spectrum highlighted a change in the variability patterns of fluvial systems between 2000 and 2010 characterised by a shift towards a quasi-decadal process (8-12 years) domain. The Intertropical Convergence Zone (ITCZ), El Niño - Southern Oscillation (ENSO) events, and quasi-decadal climate processes are the main factors controlling the fluvial discharge variability of these fluvial systems.

    A good understanding of diurnal warming in the upper ocean is important for the validation of satellite-derived sea surface temperature (SST) against in-situ buoy data and for merging satellite SSTs taken at different times of the same day. For shallow coastal regions, better understanding of diurnal heating could also help improve monitoring and prediction of ecosystem health, such as coral reef bleaching. Compared to its open ocean counterpart which has been studied extensively and modeled with good success, coastal diurnal warming has complicating localized characteristics, including coastline geometry, bathymetry, water types, tidal and wave mixing. Our goal is to characterize coastal diurnal warming using two extensive in-situ temperature and weather datasets from the Caribbean and Great Barrier Reef (GBR), Australia. Results showed clear daily warming patterns in most stations from both datasets. For the three Caribbean stations where solar radiation is the main cause of daily warming, the mean diurnal warming amplitudes were about 0.4 K at depths of 4-7 m and 0.6-0.7 K at shallower depths of 1-2 m; the largest warming value was 2.1 K. For coral top temperatures of the GBR, 20% of days had warming amplitudes >1 K, with the largest >4 K. The bottom warming at shallower sites has higher daily maximum temperatures and lower daily minimum temperatures than deeper sites nearby. The averaged daily warming amplitudes were shown to be closely related to daily average wind speed and maximum insolation, as found in the open ocean. Diurnal heating also depends on local features including water depth, location on different sections of the reef (reef flat vs. reef slope), the relative distance from the barrier reef chain (coast vs. lagoon stations vs. inner barrier reef sites vs. outer rim sites); and the proximity to the tidal inlets. In addition, the influence of tides on daily temperature changes and its relative importance compared to solar radiation was quantified by

    Spatial and temporal biodiversity patterns of free-living marine nematodes were studied in Cienfuegos Bay, a tropical semi-enclosed basin in the Caribbean Sea. Taxonomic (to species level) and functional (biological trait) approaches were applied for describing the assemblage structure and relating it to abiotic environment based on a sampling scheme in six subtidal stations and three months. Biological trait approach added relevant information to species pattern regarding relationships between diversity patterns and the abiotic environment. The most common morphotypes were deposit feeding nematodes, with colonising abilities of 2-3 (in a scale from 1 to 5), tail conical cylindrical or filiforme and body slender; and their abundance were correlated with depth, organic matter and silt/clay fraction. In spite of a high turnover of species, functional diversity of assemblages did not change notably in space and time. A result probably due to sampling of the habitat pool of species and to low heterogeneity of the studied muddy bottoms. Chemical pollution (organic enrichment and heavy metals) and hydrodynamic regime possibly drove the biodiversity patterns. Spatial distribution of assemblages support the existence of two well differentiated basins inside the bay, the northern basin more polluted than the southern one. The low hydrodynamic regime would determine a poor dispersion of nematodes resulting in high spatial variance in the assemblage structure; and also the associated hypoxic conditions and pollutants in sediments can explain the dominance of tolerant nematode species such as Daptonema oxycerca, Sabatieria pulchra, Terschellingia gourbaultae, and Terschellingia longicaudata. A comparison of spatial-temporal patterns of biodiversity between Cienfuegos Bay and other semi-enclosed bays in temperate regions suggests several similarities: nematode assemblages are strongly influenced by anthropogenic disturbance, temporal trends are weak or overridden by spatial

    Whale sharks, Rhincodon typus, aggregate by the hundreds in a summer feeding area off the northeastern Yucatan Peninsula, Mexico, where the Gulf of Mexico meets the Caribbean Sea. The aggregation remains in the nutrient-rich waters off Isla Holbox, Isla Contoy and Isla Mujeres, Quintana Roo for several months in the summer and then dissipates between August and October. Little has been known about where these sharks come from or migrate to after they disperse. From 2003-2012, we used conventional visual tags, photo-identification, and satellite tags to characterize the basic population structure and large-scale horizontal movements of whale sharks that come to this feeding area off Mexico. The aggregation comprised sharks ranging 2.5-10.0 m in total length and included juveniles, subadults, and adults of both sexes, with a male-biased sex ratio (72%). Individual sharks remained in the area for an estimated mean duration of 24-33 days with maximum residency up to about 6 months as determined by photo-identification. After leaving the feeding area the sharks showed horizontal movements in multiple directions throughout the Gulf of Mexico basin, the northwestern Caribbean Sea, and the Straits of Florida. Returns of individual sharks to the Quintana Roo feeding area in subsequent years were common, with some animals returning for six consecutive years. One female shark with an estimated total length of 7.5 m moved at least 7,213 km in 150 days, traveling through the northern Caribbean Sea and across the equator to the South Atlantic Ocean where her satellite tag popped up near the Mid-Atlantic Ridge. We hypothesize this journey to the open waters of the Mid-Atlantic was for reproductive purposes but alternative explanations are considered. The broad movements of whale sharks across multiple political boundaries corroborates genetics data supporting gene flow between geographically distinct areas and underscores the need for management and conservation strategies for

    Vibrio spp. are associated with waterbirds mainly in temperate latitudes. We evaluated the prevalence and distribution of Vibrio spp. from fecal samples of resident and migratory aquatic birds collected during October 2011 and March 2012 at two coastal sites in the tropical southern Caribbean Sea. We amplified DNA by PCR in 40% of samples, resulting in 47% and 36% estimated prevalence for resident and migratory birds in Cuare Wildlife Refuge, and 33% and 44% in Margarita Island, respectively. We found nontoxigenic Vibrio cholerae in Cuare Wildlife Refuge with a higher prevalence in resident birds (18%). Our PCR results for Vibrio and V. cholerae were not significantly different between sites or bird migratory status. The 16S rRNA phylogenetic analysis sequences from fecal samples from Cuare Wildlife Refuge were highly similar to V. cholerae and Vibrio vulnificus , whereas sequences from Margarita Island samples formed clusters with species related to the Harveyi clade. Our findings indicate that several species of Vibrio are common in aquatic birds along the southern Caribbean Sea and contribute to our understanding of the role of birds as possible reservoirs of potentially pathogenic bacteria.

    The Caribbean Sea and adjacent land areas are highly sensitive to the projected impacts of global climate change. The countries bordering the Caribbean Sea depend heavily on coastal and marine assets as a major source of livelihood support. Rising sea surface temperatures (SSTs) are known to be associated with coral bleaching, ocean acidification, and other phenomena that threaten livelihoods in the region. The paucity of SST systematic observations in both the Caribbean Sea and adjoining Western Atlantic waters is a limiting factor in the projection of future climate change impacts on the region's marine resources. Remote sensing of SST by satellites began only within the last three decades and although the data collected so far might be insufficient to provide conclusive definitions of long-term SST variations in the Caribbean waters, these data along with the output from climate model simulations provide a useful basis for gaining further insights into plausible SST futures under IPCC SRES scenarios. In this paper, we examine the recent SST records from the NESDIS AVHRR satellite data and NOAA Optimum Interpolation (OI) sea surface temperature V2 and provide a comparative analysis of projected SST changes for the Caribbean Sea up to the end of the twenty-first century, under the SRES A2 and B2 scenarios' simulations of the sea surface skin temperatures (SSsT) using the Hadley Centre's regional model, PRECIS. The implications of these projected SST changes for bleaching of coral reefs, one of the region's most valuable marine resource, and for rainfall are also discussed.

    We have expanded the previously available quality-controlled database of relative sea-level (RSL) observations for the U.S. Atlantic coast with data from the Atlantic coast of Canada, the Pacific coast of North America and the Caribbean. The Holocene sea-level database for the U.S. Atlantic coast consisted of 836 sea-level indicators. The database documented a decreasing rate of relative sea-level (RSL) rise through time with no evidence of sea level being above present in the middle to late Holocene. The highest rates of rise were found in the mid-Atlantic region. We employed the database to constrain an ensemble of glacial isostatic adjustment (GIA) models using two ice (ICE-5G and ICE-6G) and two mantle viscosity variation (VM5a and VM5b). We identified significant misfits between observations and predictions using ICE-5G with the VM5a viscosity profile. ICE-6G provides some improvement for the northern Atlantic region, but misfits remain elsewhere. Decreasing the upper mantle and transition zone viscosity from 0.5*1021 Pa s (VM5a) to 0.25*1021 Pa s (VM5b) removed significant discrepancies between observations and predictions along the mid-Atlantic coastline, although misfits remained in the southern Atlantic region. The addition of new data from areas more proximal and distal to Laurentide ice loading has allowed us to further investigate the VM5b mantle viscosity profile.

    Full Text Available Cloud optical properties in the trade winds over the Eastern Caribbean Sea have been shown to be sensitive to cloud condensation nuclei (CCN concentrations. The objective of the current study was to investigate the CCN properties in the marine boundary layer (MBL in the Eastern Caribbean, in order to assess the respective roles of organic species, long-range transported mineral dust, and sea salt particles. Measurements were carried out in June–July 2013, on the East Coast of Barbados and included CCN number concentrations, particle number size distributions, as well as off-line analysis of sampled particulate matter (PM and sampled accumulation mode particles for an investigation of composition and mixing state with transmission electron microscopy (TEM in combination with energy-dispersive X-ray spectroscopy (EDX. During most of the campaign, significant mass concentrations of long-range transported mineral dust was present in the PM, and influence from local island sources can be ruled out. The CCN and particle number concentrations were similar to what can be expected in pristine marine environments. The hygroscopicity parameter κ was inferred, and values in the range 0.2–0.5 were found during most of the campaign, with similar values for the Aitken and the accumulation mode. The accumulation mode particles studied with TEM were dominated by non-refractory material, and concentrations of mineral dust, sea salt, and soot were too small to influence the CCN properties. It is highly likely that the CCN were dominated by a mixture of sulphate species and organic compounds.

    Costa Rica is located on the Central American Isthmus, which receives moisture inputs directly from the Caribbean Sea and the Eastern Pacific Ocean. This location includes unique mountainous and lowland microclimates, but only limited knowledge exists about the impact of relief and regional atmospheric circulation patterns on precipitation origin, transport, and isotopic composition. Therefore, the main scope of this project is to identify the key drivers controlling stable isotope variations in daily-scale precipitation of Costa Rica. The monitoring sites comprise three strategic locations across Costa Rica: Heredia (Central Valley), Turrialba (Caribbean slope), and Caño Seco (South Pacific slope). Sporadic dry season rain is mostly related to isolated enriched events ranging from -5.8‰ to -0.9‰ δ18O. By mid-May, the Intertropical Convergence Zone reaches Costa Rica resulting in a notable depletion in isotope ratios (up to -18.5‰ δ18O). HYSPLIT air mass back trajectories indicate the strong influence on the origin and transport of precipitation of three main moisture transport mechanisms, the Caribbean Low Level Jet, the Colombian Low Level Jet, and localized convection events. Multiple linear regression models constructed based on Random Forests of surface meteorological information and atmospheric sounding profiles suggest that lifted condensation level and surface relative humidity are the main factors controlling isotopic variations. These findings diverge from the recognized 'amount effect' in monthly composite samples across the tropics. Understanding of stable isotope dynamics in tropical precipitation can be used to a) enhance groundwater modeling efforts in ungauged basins where scarcity of long-term monitoring data drastically limit current and future water resources management, b) improve the re-construction of paleoclimatic records in the Central American land bridge, c) calibrate and validate regional circulation models.

  11. Punishing the sea wolf: corsairs and cannibals in the early modern Caribbean

    Full Text Available Looks at how Western law was interpreted and applied to perceived cannibals and corsairs in the Spanish Caribbean in the 16th and 17th c., by Spanish jurists in the period, and at the development of the cannibal and corsair image in Spanish culture. Author outlines the convergence of terms suggesting a growing semantic linkage between certain indigenous peoples, specially the famed "Carib cannibals", and foreign, mostly Western European, corsairs poaching on Spanish wealth. He describes how of the Caribs, said to be cannibals, involved in piracy, an image was constructed of not only cannibals, but also greedy criminals, or rebelers against Catholicism, in order to (legally justify punishments or wars against them, and thus Spanish rule. He then discusses how of French, British, and other corsairs in the Caribbean involved in piracy against the Spanish, an in some ways similar image was painted of fanatical canine types ruled by appetites, and also of anti-Catholic heretics and criminals, in order to justify punishments as well as the Spanish claim on rule of the Caribbean.

    This study evaluated the relationship between the indices known as the Reef Health Index (RHI) and two-dimensional Coral Health Index (2D-CHI) and different representative metrics of biological, ecological and functional diversity of fish and corals in 101 reef sites located across seven zones in the western Caribbean Sea. Species richness and average taxonomic distinctness were used to asses biological estimation; while ecological diversity was evaluated with the indices of Shannon diversity and Pielou´s evenness, as well as by taxonomic diversity and distinctness. Functional diversity considered the number of functional groups, the Shannon diversity and the functional Pielou´s evenness. According to the RHI, 57.15% of the zones were classified as presenting a "poor" health grade, while 42.85% were in "critical" grade. Based on the 2D-CHI, 28.5% of the zones were in "degraded" condition and 71.5% were "very degraded". Differences in fish and coral diversity among sites and zones were demonstrated using permutational ANOVAs. Differences between the two health indices (RHI and 2D-CHI) and some indices of biological, ecological and functional diversity of fish and corals were observed; however, only the RHI showed a correlation between the health grades and the species and functional group richness of fish at the scale of sites, and with the species and functional group richness and Shannon diversity of the fish assemblages at the scale of zones. None of the health indices were related to the metrics analyzed for the coral diversity. In general, our study suggests that the estimation of health indices should be complemented with classic community indices, or should at least include diversity indices of fish and corals, in order to improve the accuracy of the estimated health status of coral reefs in the western Caribbean Sea.

    We radio-marked nesting white-tailed tropicbirds at Culebra National Wildlife Refuge, Puerto Rico, and tracked them from a Cessna 182 during flights over the open sea. Locations of the birds were determined using standard aerial telemetry techniques for side-facing Yagi antennas. We used strut-mounted, 4-element Yagi antennas connected to a switchbox and scanning receiver. By recording bearing and distance from at least 1 of 3 aeronautical navigation beacons, the position of the aircraft and the bird could be estimated with an error of about 2 km. On several occasions we plotted the general heading of a bird and then relocated and tracked the same bird on the following day. Our method of aerial tracking and navigation was useful for tracking birds over the sea to at least 116 km from the breeding colony

  10. Statistical downscaling of IPCC sea surface wind and wind energy predictions for U.S. east coastal ocean, Gulf of Mexico and Caribbean Sea

    A multivariate statistical downscaling method is developed to produce regional, high-resolution, coastal surface wind fields based on the IPCC global model predictions for the U.S. east coastal ocean, the Gulf of Mexico (GOM), and the Caribbean Sea. The statistical relationship is built upon linear regressions between the empirical orthogonal function (EOF) spaces of a cross- calibrated, multi-platform, multi-instrument ocean surface wind velocity dataset (predictand) and the global NCEP wind reanalysis (predictor) over a 10 year period from 2000 to 2009. The statistical relationship is validated before applications and its effectiveness is confirmed by the good agreement between downscaled wind fields based on the NCEP reanalysis and in-situ surface wind measured at 16 National Data Buoy Center (NDBC) buoys in the U.S. east coastal ocean and the GOM during 1992-1999. The predictand-predictor relationship is applied to IPCC GFDL model output (2.0°×2.5°) of downscaled coastal wind at 0.25°×0.25° resolution. The temporal and spatial variability of future predicted wind speeds and wind energy potential over the study region are further quantified. It is shown that wind speed and power would significantly be reduced in the high CO2 climate scenario offshore of the mid-Atlantic and northeast U.S., with the speed falling to one quarter of its original value.

  11. Seismic structure of ultra-slow spreading crust formed at the Mid-Cayman Spreading Centre, Caribbean Sea

    About 57% of the Earth's surface is covered by oceanic crust and new ocean floor is continuously created along the ~60.000 km long mid-ocean ridge (MOR) system. About 25% of the MOR spread at an ultra-slow spreading rate of spreading rates the melt supply to the ridge is thought to dramatically decrease and crustal thickness decreases to a thickness of spreading rates. A formation of crust from a magma chamber would suggest the creation of a well stratified crust, with an extrusive upper crust (layer 2) and a lower gabbroic crust (lower 3) and a well-defined crust-mantle boundary and hence a seismic Moho. In contrast, decompressional melting without formation of a magma chamber would support a crustal structure where seismic velocities change gradually from values typical of crustal rocks to mantle rocks. Here, we report initial results from a survey from the ultra-slow spreading Cayman Spreading Centre in the Caribbean Sea, sampling mature crust along a flowline from both conjugated ridge flanks. The seismic refraction and wide-angle survey was conducted using ocean-bottom-seismometers from Germany, the UK, and Texas and a 5500 cubic-inch airgun-array source towed by the German research vessel METEOR in April 2015. Typical crustal velocities support a thin crust of 3 to 5 km thickness. However, a well-defined Moho boundary was not observed. Thus, velocities change gradually from crustal-type velocities (<7.2 km/s) to values of 7.6-7.8 km/s, supporting mantle rocks. We suggest that reduced mantle velocities indicate gabbroic intrusions within the mantle rather than indicating serpentinization.

  12. Isotopic record of Pleistocene glacial/interglacial cycles in pelagic carbonates: Revisiting historical data from the Caribbean Sea

    Science.gov (United States)

    Hermoso, Michaël

    2016-04-01

    The glacial/interglacial cycles of the Pleistocene were first recognised by variations in the oxygen isotopic composition of planktonic foraminifera from cores in the Caribbean Sea. Since this pioneering work by Emiliani, this proxy has been extensively applied to a variety of carbonate biominerals over the entirety of the Meso-Cenozoic. However, palaeoceanographic studies have overwhelmingly focused on foraminifera compared to other calcifying microorganism fossils, such as the coccoliths. In this study, I revisit coccolith stable isotopic data obtained from the classic P6304-4 core in light of recent developments in the biogeochemistry of coccolithophores. In particular, I show that the coccolith stable isotope record of the last 13 Marine Isotope Stages (∼480 kyrs) is significantly biased by large vital effects. The magnitude of coccolith carbon and oxygen isotope vital effects is not uniform, but shows remarkable co-variance with the Vostok CO2 ice record. During periods of relatively elevated CO2 (interstadials), the expression of the vital effect is relatively small, whereas it can as high as +3‰ for the oxygen isotopes during glacial stadials, which I argue is a result of enhanced CO2 limitation of coccolithophores. Using this paradigm, I propose that coccolithophore vital effects are not a complicating factor, but rather the signal of interest. As the magnitude of the coccolith vital effect is shown to scale with pCO2, coccolith carbon and oxygen isotopes may be used in conjunction with foraminifera data to reconstruct and refine aqueous CO2 concentrations in the past.

  13. Comparative Profiling of coral symbiont communities from the Caribbean, Indo-Pacific, and Arabian Seas

    KAUST Repository

    Arif, Chatchanit

    2014-12-01

    Coral reef ecosystems are in rapid decline due to global and local anthropogenic factors. Being among the most diverse ecosystems on Earth, a loss will decrease species diversity, and remove food source for people along the coast. The coral together with its symbionts (i.e. Symbiodinium, bacteria, and other microorganisms) is called the ‘coral holobiont’. The coral host offers its associated symbionts suitable habitats and nutrients, while Symbiodinium and coral-associated bacteria provide the host with photosynthates and vital nutrients. Association of corals with certain types of Symbiodinium and bacteria confer coral stress tolerance, and lack or loss of these symbionts coincides with diseased or bleached corals. However, a detailed understanding of the coral holobiont diversity and structure in regard to diseases and health states or across global scales is missing. This dissertation addressed coral-associated symbiont diversity, specifically of Symbiodinium and bacteria, in various coral species from different geographic locations and different health states. The main aims were (1) to expand the scope of existing technologies, (2) to establish a standardized framework to facilitate comparison of symbiont assemblages over coral species and sites, (3) to assess Symbiodinium diversity in the Arabian Seas, and (4) to elucidate whether coral health states have conserved bacterial footprints. In summary, a next generation sequencing pipeline for Symbiodinium diversity typing of the ITS2 marker is developed and applied to describe Symbiodinium diversity in corals around the Arabian Peninsula. The data show that corals in the Arabian Seas are dominated by a single Symbiodinium type, but harbor a rich variety of types in low abundant. Further, association with different Symbiodinium types is structured according to geographic locations. In addition, the application of 16S rRNA gene microarrays to investigate how differences in microbiome structure relate to

  16. Attempt of absolute dating and reconstitutions of climate changes in the Caribbean Sea: multi-proxy approaches to planktonic foraminifera and fine aragonitic fraction

    International Nuclear Information System (INIS)

    Absolute dating of climate archives is essential to better understand climate mechanisms. A marine sediment core from the Caribbean Sea enriched in fine-grained aragonite (suitable to U/Th dating) has been studied for both planktonic foraminifera tests (≥150 μm) and fine fraction (≤63 μm) over the last one million years using mineralogical and geochemical approaches. This study aims at i) examining lead/lag of δ18O and radiometric ages of the different-size fractions and ii) reconstructing paleo-environment in the area. The fine fraction mineralogy is strongly influenced by glacial-interglacial sea level changes. The offset of δ18O and 14C ages between the fine and foraminifera fractions during Termination I is partly explained by a bioturbation model. Attempt of U/Th dating to Termination II and V reveals that the fine fraction contains non-radiogenic Th, which needs further analytical development. Reconstructed surface water δ18O changes suggest a decrease in surface water salinity at the end of Mid-Pleistocene Transition related to ITCZ position over the Caribbean Sea. (author)

    We use a multilevel vector autoregressive model (VAR-L), to forecast sea surface temperature anomalies (SSTAs) in the Atlantic hurricane Main Development Region (MDR). VAR-L is a linear regression model using global SSTA data from L prior months as predictors. In hindcasts for the recent 30 years, the multilevel VAR-L outperforms a state-of-the-art dynamic forecast model, as well as the commonly used linear inverse model (LIM). The multilevel VAR-L model shows skill in 6-12 month forecasts, with its greatest skill in the months of the active hurricane season. The optimized model for the best long-range skill score in the MDR, chosen by a cross-validation procedure, has 12 time levels and 12 empirical orthogonal function modes. We investigate the optimal initial conditions for MDR SSTA prediction using a generalized singular vector decomposition of the propagation matrix. We find that the added temporal degrees of freedom for the predictands in VAR12 as compared with a LIM model, which allow the model to capture both the local wind-evaporation-SST feedback in the Tropical Atlantic and the impact on the Atlantic of an improved medium-range ENSO forecast, elevate the long-range forecast skill in the MDR.

    Two rare species of Podocotyle Dujardin, 1845 (Digenea: Opecoelidae) parasitizing five macrourid species inhabiting the deep waters of the northeastern Gulf of Mexico and Caribbean Sea off Panama are described. Podocotyle nimoyi n. sp. was found in the intestine of the pugnose grenadier, Sphagemacrurus grenadae (Parr), and the common Atlantic grenadier, Nezumia aequalis (Günther) (Gadiformes: Macrouridae), at depths of 534-995 m in the Northeast Gulf of Mexico off Florida and represents the fifth species of Podocotyle endemic to the deep sea. Podocotyle pearsei Manter, 1934, was re-described from the intestine of the bullseye grenadier, Bathygadus macrops Goode & Bean, the doublethread grenadier, Gadomus arcuatus (Goode & Bean), and the western softhead grenadier, Malacocephalus occidentalis Goode & Bean (Gadiformes: Macrouridae), collected from 591-728 m depths in the Northeast Gulf of Mexico off Florida and the Caribbean Sea off Panama. The following new host records are established: P. nimoyi n. sp. is the third parasite species known from S. grenadae and the first digenean species reported from this host; P. nimoyi n. sp. is the first reported species of Podocotyle parasitizing N. aequalis; and this is the first report of P. pearsei or any representative of the genus Podocotyle infecting B. macrops, G. arcuatus and M. occidentalis. A listing of all digenean parasites previously reported from the five macrourid species examined herein is given and some observations are made about Podocotyle in the deep sea. PMID:27395189

    The detailed stratigraphic survey and paleontological study (mollusks, corals, foraminifera and ostracods) of four low-level, ˜3 m, marine terrace sections: Punta Canoas, Manzanillo del Mar, Playa de Oro, and Tierra Bomba Island, from the Cartagena region, southern Caribbean, supplemented with 22 radiocarbon dates, reveals that the northern terraces were deposited as parasequences in a clastic depositional system compared to the Tierra Bomba Island succession that was deposited in a carbonate depositional system between ˜3600 and ˜1700 cal yrs BP. Drier conditions and the southern location of the ITCZ at about 3 ka triggered stronger easterly Trades and more dynamic southwestward sediment drift fed by the Magdalena River mouth, thus promoting the formation of sand spits that ultimately isolated the Cienaga de Tesca coastal lagoon from the Caribbean Sea. Our estimates support the hypothesis that the present position of the terraces is the product of neotectonism rather than a higher 3 ka, sea-level. Upheaval of the terraces varies between ˜3.8 mmyr -1 at Punta Canoas and ˜2.2 mmyr -1 at Tierra Bomba to ˜1.5 mmyr -1 at Manzanillo del Mar and Playa de Oro terraces. Our study corroborates previous contentions on the role of mud diapirism and the dynamics of the Dique Fault as late Holocene upheaval mechanisms.

    The aim of the present study was to evaluate the potential use of otolith microchemistry (Sr:Ca and Ba:Ca ratios) to identify silver mullet, Mugil curema, populations in Southeastern Caribbean Sea. Fish samples were collected in 7 areas of Nueva Esparta State (Venezuela). The otolith Sr:Ca and Ba:Ca ratios and water Sr:Ca were determined (by ICP-OES and EDTA volumetric method). Otoliths Sr:Ca and Ba:Ca ratios and Sr:Ca partition coefficient of mullets in Cubagua island (south of the State) were significantly different from ratios in La Guardia (north of the State). A discriminant analysis of otolith Sr:Ca and Ba:Ca ratios separated Cubagua Island from La Guardia values. These results suggest the existence of different mullet groups in the Southeastern Caribbean Sea. For this, the simultaneous use of Sr:Ca and Ba:Ca ratios could be a potential tool to identify populations in the study area. PMID:26628220

  3. Reconstruction of the oceanic nitrate inventory in the Pliocene Caribbean Sea: Foraminifera-bound δ15N - A new approach

    The nitrate budget in the low-latitude surface ocean is mainly controlled by the opposing effects of denitrification and nitrate fixation. The state of the global ocean nitrate inventory highly affects primary production, which allows sequestering CO2 into the deep ocean. This may influence climate variability and control warm and cold periods in Earth history. Studies have shown that nitrogen isotopes reflect the nutrient status of the upper water column and therefore can be used as proxy for the state of the ocean’s ‘biological pump’. The nitrate inventory has mostly been reconstructed based on bulk sedimentary N-isotope measurements, which can be affected by syn- and post-sedimentary processes. Promising approaches to circumvent these potential biases are based on measurements of foraminifera-bound δ15N isotopes. In the subtropical and tropical ocean, planktonic foraminifera are a main component of the sinking particle flux. The organic compounds encapsulated within the foraminiferal tests are protected from sedimentary diagenetic processes and record a pristine signal of the nitrate composition of the upper water column. The novel method used in this study employs denitrifying bacteria (Pseudomonas chlororaphis and Pseudomonas aureofaciens) to produce nitrous oxide (N2O), recovered from the nitrate extracted from the organic matter sheltered within the foraminifera shell. The extracted N2O is analyzed for δ15N with a Gas bench II - IRMS and yields results with reproducible isotopic measurements of samples with nitrate concentrations down to 1 μM. Previous data from the investigated site (ODP Leg 165, Site 999A, Caribbean Sea), spanning the last 30’000 yrs using the same method, indicate a systematic difference between glacial and interglacial values. The glacial state is characterized by high δ15N values around ~ 5 ‰ (suggesting less N-fixation) and the interglacial by low δ15N values around ~ 3 ‰ (N-fixation increase). Pliocene data from

    Part of the solar energy can be harvested and used in different processes. Taking advantage of the natural temperature gradient between the surface and deep ocean, the Ocean Thermal Energy Conversion (OTEC) process fulfills this goal. The IMPALA project (Impacts of artificial upwelling on microplankton) aims to study the potential environmental impacts of releasing, below the surface, deep seawater flowing out of a scheduled OTEC pilot plant offshore the Martinique Island in the Caribbean Sea. Biogeochemical processes involved in the artificial upwelling generated by the use of an Ocean Thermal Energy Conversion (OTEC) plant were studied in this poor nutrient environment. The biogeochemical and physical ecosystem structure and functioning on the OTEC site were described and deep seawater discharge using in situ microcosm experiments was carried out off Martinique. Surface seawater was collected in ultra-clean conditions at two depths (corresponding to the maximum of chlorophyll a concentration and bottom of nutricline) and mixed in different proportions with deep seawater (2% and 10%). Pigments determination, picophytoplankton abundance, macro-nutrients (silicates, nitrates, and phosphates), particular organic carbon and nitrogen concentrations and primary production were documented to assess the variability between the natural environment and within the microcosms. The latter were immersed for 6 days on a 250 meters mooring. Variations observed in microcosms experiments and in the surrounding waters were compared in order to evaluate the natural variability of the phytoplankton assemblage and the potential shifts induced by deep water supply. Results obtained during two fields campaigns conducted off Martinique at the onset of the dry (November-December 2013) and wet seasons (June 2014), respectively, will be presented and discussed. Incubating mixtures of subsurface and deep waters at two ratios and at two depths, allows evaluating the potential impact of a deep

    A large and consistent thermal resource exists in the area between 13--15/sup 0/ North latitude and 75--80/sup 0/ West longitude, which was studied for possible use by a plant ship. The area studied is primarily in the Colombian Basin of the Caribbean Sea. The average annual ..delta..T (surface temperature minus temperature at depth) for the area at 1000 meters is 22.4/sup 0/C. At 650 meters, an adequate ..delta..T exists, with no month of the year having a mean ..delta..T less than 19/sup 0/C. The total variability of temperature at all depths in this Caribbean area is small. Below 1000 meters, the total variation is extremely small. The area has a good mixed layer at all times of the year. It is occasionally exposed to strong winds from hurricanes. Currents generally show the same general pattern throughout the year with a predominant flow toward the west or northwest at average speeds of 40--50 cm/sec.

  7. ICE-6G models of postglacial relative sea-level history applied to Holocene coral reef and mangrove records of the western Caribbean

    Fossil coral reefs and mangrove peat accumulations at western Caribbean sites along a latitudinal gradient from the Florida Keys through Belize and Panama provide dated and interpreted 8,000 year Holocene sea-level records for comparison with RSL predictions of the ICE-6G (VM5A, VM5B; L90) models of glacio-hydro-isostatic adjustment, with and without rotational feedback. These presumably passive continental margin sites provide the means to establish a N-S spatial trend in the varying influences of GIA, eustatic components of Holocene sea level, extent of forebulge collapse and influence of rotational feedback over a 20° latitudinal range. Previous ICE6G (VM5A) model-coral data comparisons for St Croix, USVI, Antigua, Martinique and Barbados (Toscano, Peltier and Drummond, 2011, QSR) along the eastern Caribbean plate and island arc illustrated the close model-data compatibility, the influence of rotational feedback acting as a significant factor in reducing misfits, and the need for high quality in situ data to confirm the extension of the proglacial forebulge into tropical latitudes. The gradient of western Caribbean continental shelf sites comprises a much more varied range of model-data relationships based on extensive combined Acropora palmata (reef crest coral) and Rhizophora mangle (microtidal mangrove) peat datasets in all cases. Starting at the northernmost region with the Florida Keys, there exist negative model misfits to the data, suggesting the possibility of a positive tectonic overprint upon expectations related to the glacial isostatic adjustment process acting alone, even though this region is normally believed to be tectonically stable. The largest multi-proxy database from Belize supports the likelihood of increasing rates of subsidence from north to south in the Belize Lagoon, which may account for numerous positive GIA model-data misfits. The southernmost site at Panama is most similar to Belize in the possible nature of tectonic influences on

    Water that forms the Florida Current, and eventually the Gulf Stream, coalesces in the Caribbean from both subtropical and equatorial sources. The equatorial sources are made up of, in part, South Atlantic water moving northward and compensating for southward flow at depth related to meridional overturning circulation. Subtropical surface water contains relatively high amounts of radiocarbon ({sup 14}C), whereas equatorial waters are influenced by the upwelling of low {sup 14}C water and have relatively low concentrations of {sup 14}C. We use a 250 year record of {delta}{sup 14}C in a coral from southwestern Puerto Rico along with previously published coral {delta}{sup 14}C records as tracers of subtropical and equatorial water mixing in the northern Caribbean. Data generated in this study and from other studies indicate that the influence of either of the two water masses can change considerably on interannual to interdecadal time scales. Variability due to ocean dynamics in this region is large relative to variability caused by atmospheric {sup 14}C changes, thus masking the Suess effect at this site. A mixing model produced using coral {delta}{sup 14}C illustrates the time varying proportion of equatorial versus subtropical waters in the northern Caribbean between 1963 and 1983. The results of the model are consistent with linkages between multidecadal thermal variability in the North Atlantic and meridional overturning circulation. Ekman transport changes related to tradewind variability are proposed as a possible mechanism to explain the observed switches between relatively low and high {delta}{sup 14}C values in the coral radiocarbon records.

    Integrative taxonomy, in which multiple disciplines are combined to address questions related to biological species diversity, is a valuable tool for identifying pelagic marine fish larvae and recognizing the existence of new fish species. Here we combine data from DNA barcoding, comparative morphology, and analysis of color patterns to identify an unusual fish larva from the Florida Straits and demonstrate that it is the pelagic larval phase of a previously undescribed species of Liopropoma sea bass from deep reefs off Curaçao, southern Caribbean. The larva is unique among larvae of the teleost family Serranidae, Tribe Liopropomini, in having seven elongate dorsal-fin spines. Adults of the new species are similar to the golden bass, Liopropoma aberrans, with which they have been confused, but they are distinct genetically and morphologically. The new species differs from all other western Atlantic liopropomins in having IX, 11 dorsal-fin rays and in having a unique color pattern-most notably the predominance of yellow pigment on the dorsal portion of the trunk, a pale to white body ventrally, and yellow spots scattered across both the dorsal and ventral portions of the trunk. Exploration of deep reefs to 300 m using a manned submersible off Curaçao is resulting in the discovery of numerous new fish species, improving our genetic databases, and greatly enhancing our understanding of deep-reef fish diversity in the southern Caribbean. Oh the mother and child reunion is only a moment away. Paul Simon. PMID:24825118

    Nutrient inputs associated with coastal population growth threaten the integrity of coastal ecosystems around the globe. In order to assess the threat posed by rapid growth in tourism, we analyzed the nutrient concentrations as well as the δ15N of NO 3- and macrophytes to detect wastewater nitrogen (N) at 6 locations along a groundwater-dominated coastal seagrass bed on the Caribbean coast of Mexico. We predicted that locations with greater coastal development would have higher concentrations of dissolved inorganic nitrogen (DIN) and phosphorus (P), as well as δ15N of NO 3-, reflecting wastewater sources of N. However, concentrations of NO 3- were not significantly different between developed (3.3 ± 5.3 μM NO 3-) and undeveloped (1.1 ± 0.7 μM) marine embayments. The most important control on DIN concentration appeared to be mixing of fresh and salt water, with DIN concentrations negatively correlated with salinity. The δ15N of NO 3- was elevated at an inland pond (7.0 ± 0.42‰) and a hydrologically-connected tide pool (7.6 ± 0.57‰) approximately 1 km downstream of the pond. The elevated δ15N of NO 3- at the pond was paralleled by high δ15N values of Cladophora sp., a ubiquitous green alga (10 ± 1‰). We hypothesize that inputs of nitrogen rich (NO 3- > 30 μM) groundwater, characterized by 15N enriched signatures, flow through localized submarine groundwater discharges (SGD) and contribute to the elevated δ15N signatures observed in many benthic macrophytes. However, changes in nitrogen concentrations and isotope values over the salinity gradient suggest that other processes (e.g. denitrification) could also be contributing to the 15N enrichments observed in primary producers. More measurements are needed to determine the relative importance of nitrogen transformation processes as a source of 15N to groundwaters; however, it is clear that continued inputs of anthropogenic N via SGD have the potential to severely impact ecologically and economically

    During the last century, three different ways of interpreting the tectonic evolution of the Gulf of Mexico and the Caribbean have been proposed, taking into account the Bailey Willis School of a permanent pre-Jurassic deep sea basin, the Edward Suess School of a subsided continental terrain, and the Alfred Wegener School of continental separation. The present investigation is concerned with an outline of an interpretation which follows that of Pindell and Dewey (1982). An attempt is made to point out ways in which the advanced hypotheses can be tested. The fit of Africa, North America, and South America is considered along with aspects of relative motion between North and South America since the early Jurasic. Attention is given to a framework for reconstructing Caribbean plate evolution, the evolution of the Caribbean, the plate boundary zones of the northern and southern Caribbean, and the active deformation of the Caribbean plate.

    Collecting reef-fish specimens using a manned submersible diving to 300 m off Curaçao, southern Caribbean, is resulting in the discovery of numerous new fish species. The new Liopropoma sea bass described here differs from other western Atlantic members of the genus in having VIII, 13 dorsal-fin rays; a moderately indented dorsal-fin margin; a yellow-orange stripe along the entire upper lip; a series of approximately 13 white, chevron-shaped markings on the ventral portion of the trunk; and a reddish-black blotch on the tip of the lower caudal-fin lobe. The new species, with predominantly yellow body and fins, closely resembles the other two “golden basses” found together with it at Curaçao: L. aberransand L. olneyi. It also shares morphological features with the other western Atlantic liopropomin genus,Bathyanthias. Preliminary phylogenetic data suggest that western Atlantic liopropomins, includingBathyanthias, are monophyletic with respect to Indo-Pacific Liopropoma, and that Bathyanthias is nested within Liopropoma, indicating a need for further study of the generic limits of Liopropoma. The phylogenetic data also suggest that western Atlantic liopropomins comprise three monophyletic clades that have overlapping depth distributions but different depth maxima (3–135 m, 30–150 m, 133–411 m). The new species has the deepest depth range (182–241 m) of any known western Atlantic Liopropomaspecies. Both allopatric and depth-mediated ecological speciation may have contributed to the evolution of western Atlantic Liopropomini.

  14. Immune response of the Caribbean sea fan, Gorgonia ventalina, exposed to an Aplanochytrium parasite as revealed by transcriptome sequencing

    Full Text Available Coral reef communities are undergoing marked declines due to a variety of stressors including disease. The sea fan coral, Gorgonia ventalina, is a tractable study system to investigate mechanisms of immunity to a natural occurring pathogen. Functional studies in Gorgonia ventalina immunity indicate that several key pathways and cellular responses are involved in response to natural microbial invaders, although to date the functional and regulatory pathways remain largely un-described. This study used short-read sequencing (Illumina GAIIx to identify genes involved in the response of G. ventalina to a naturally occurring Aplanochytrium spp. parasite. De novo assembly of the G. ventalina transcriptome yielded 90,230 contigs of which 40,142 were annotated. RNA-Seq analysis revealed 210 differentially expressed genes in sea fans exposed to the Aplanochytrium parasite. Differentially expressed genes involved in immunity include pattern recognition molecules, anti-microbial peptides, and genes involved in wound repair and reactive oxygen species formation. Gene enrichment analysis indicated eight biological processes were enriched representing 36 genes, largely involved with protein translation and energy production. This is the first report using high-throughput sequencing to characterize the host response of a coral to a natural pathogen. Furthermore, we have generated the first transcriptome for a soft (octocoral or non-scleractinian coral species. Expression analysis revealed genes important in invertebrate innate immune pathways, as well as those whose role is previously un-described in cnidarians. This resource will be valuable in characterizing G. ventalina immune response to infection and co-infection of pathogens in the context of environmental change.

    Tsunami warning and watch services are currently provided to the Caribbean region through a collaborative effort between the two NOAA Tsunami Warning Centers (TWCs): the Pacific Tsunami Warning Center (PTWC) in Ewa Beach, Hawaii, and the West Coast/Alaska Tsunami Warning Center (WCATWC) in Palmer, Alaska. The WCATWC, in coordination with the Puerto Rico Seismic Network (PRSN), provides fast-response warning services to the U.S. territories of the Commonwealth of Puerto Rico and the U.S. Virgin Islands (PR/VI). The PTWC provides regional watch services to other countries throughout and surrounding the Caribbean Sea as part of the Intergovernmental Coordination Group for the Caribbean Sea and Adjacent Regions. This collaboration is analogous to the TWC's responsibilities in the Pacific basin: the WCATWC provides fast-response warning services for the U.S. west coast states, Alaska, and British Columbia in Canada, while the PTWC provides regional services for countries throughout and surrounding the Pacific Ocean (as well as a fast-response service for the U.S. State of Hawaii). Caribbean seismic data are transmitted to the TWCs through several means. The PRSN directly exports data to the WCATWC, providing the Center sufficient seismic data for the PR/VI region. Additionally, the PRSN provides the TWCs with data gathered from other Caribbean nations. Using modern communication capabilities, the seismic data can be processed at the TWCs at the same time it is processed locally. Another source of high- quality seismic data is the new USGS nine-station array that circles the region. The Global Seismic Network maintains several stations in Caribbean, Central American, and South American nations which are available in real-time to the TWCs. Unfortunately, sea level data coverage is sporadic in the region. The PR/VI has a relatively dense array of coastal tide gages, but coastal tide gage coverage is very sparse for the rest of the Caribbean basin. Three deep-ocean pressure

The data comes from a survey of fisheries research during the dry season (February of 2006 between Puerto Estrella ( La Guajira and Santa Marta ( Magdalena . Biological samples were taken with a bottom trawl net (< 50 m and 50- 100 m stratum of depth following a systematic design survey. The mature fishes with higher sizes were mainly located in the sector between Manaure and Punta Gallinas, where the continental shelf is very wide and the local oceanography is modulated by the seasonal upwelling. The juvenile fishes were found toward the south of the study area between Boca Camarones and the Rio Buritaca, close to the coast. In this sector the continental shelf is very narrow with high biological productivity for the presence of rivers, mangroves and sea grasses, which serve as feeding grounds and nursery habitat for E. argenteus. In general, our results suggest that environmental conditions were important determinants of spatial distribution of abundance and sizes of E. argenteus in the north zone of the Colombian Caribbean Sea, with temperature and depth as variables that better predict the spatial distribution of this specie.

    Full Text Available Reviews development in the Caribbean, especially since 1990 to the present, and highlights future development prospects. Author discusses 2 reports from 2005 on present developments problems in the Caribbean region: the economics-focussed 'A time to choose: Caribbean development in the 21st century' by the World Bank, and the UN ECLAC report 'The Millennium Development Goals: a Latin American and Caribbean perspective', with a broader, also social and political, development agenda. He relates what both reports recommend for the Caribbean on the basis of their evaluations of past development. The World Bank report advocates a move toward the services sector, including tourism, offshore education, ICT services, and health services as most viable. The ECLAC report notes some social and political advances in comparison to other developing countries, but also remaining problems and inequalities. The author finds that the World Bank report's neoliberal, one-size-fits-all approach is not mindful of specific Caribbean realities, while the ECLAC study is more sensitive to local realities, and espouses a mixed economy. He thus considers the ECLAC approach preferable, but argues that it needs to go further, as it excludes Cuba and Haiti as atypical states.

    The non-native seagrass Halophila stipulacea has spread rapidly throughout the Caribbean Sea (Willette et al. 2014); without additional research, the ecological ramifications of this invasion are difficult to predict. Biodiversity, connectivity of marine ecosystems, and recovery of degraded coral reefs could all be affected. The invasive seagrass, native to the Red Sea and Indian Ocean, has taken over sand bottoms and intermixed with or replaced native seagrasses, including Thalassia testudinum, Syringodium filiforme, and Halodule wrightii.

    Floating and washed-up pumices have been reported by scientific expeditions along the Caribbean Sea coast of the Central American Isthmus and the northern coast of South America since at least 1947. Local coastal communities have been utilizing this resource for many years. The rounded and buffered morphology of hand specimens is consistent with water-borne transit. The volcanically active Caribbean and Central American regions provide a number of candidates for source volcanoes and eruptions. We have attempted to identify this source using samples collected from Carrie Bow Cay and Placencia Beach, Belize; Tulum Beach, Mexico; Morrosquillo Bay, Colombia; and Galeta Point, Panama. We have tracked possible transport routes through the use of river drainage and ocean current maps. The criteria for comparing the products of potential source volcanoes (including Atitlán Caldera in Guatemala and Caribbean sources such as Mt. Pelée, Martinique and Soufrière Hills, Montserrat) were developed from the whole rock major and trace element geochemistry and the compositional and textural characteristics of pumice and their constituent minerals and glasses. The largest pumice sample collected from Carrie Bow Cay, Belize, was 18.5x12 cm with the typical, rounded morphology and distinctively stretched vesicles exhibited by this pumice collection.

    Coral growth rates are highly dependent on environmental variables such as sea surface temperature and solar irradiance. Multi-decadal variability in coral growth rates has been documented throughout the Caribbean over the past 150-200 years, and linked to variations in Atlantic sea surface temperatures. Multi-decadal variability in sea surface temperatures in the North Atlantic, in turn, has been linked to volcanic and anthropogenic aerosol forcing. Here, we examine the drivers of changes in coral growth rates in the western Caribbean between 1880 and 2000, using previously published coral growth chronologies from two sites in the region, and a numerical model. Changes in coral growth rates over this period coincided with variations in sea surface temperature and incoming short-wave radiation. Our model simulations show that variations in the concentration of anthropogenic aerosols caused variations in sea surface temperature and incoming radiation in the second half of the twentieth century. Before this, variations in volcanic aerosols may have played a more important role. With the exception of extreme mass bleaching events, we suggest that neither climate change from greenhouse-gas emissions nor ocean acidification is necessarily the driver of multi-decadal variations in growth rates at some Caribbean locations. Rather, the cause may be regional climate change due to volcanic and anthropogenic aerosol emissions.

    Identifying and dating first human colonization of new places is challenging, especially when group sizes were small and material traces of their occupations were ephemeral. Generating reliable reconstructions of human colonization patterns from intact archaeological sites may be difficult to impossible given post-depositional taphonomic processes and in cases of island and coastal locations the inundation of landscapes resulting from post-Pleistocene sea-level rise. Paleoenvironmental reconstruction is proving to be a more reliable method of identifying small-scale human colonization events than archaeological data alone. We demonstrate the method through a sediment-coring project across the Lesser Antilles and southern Caribbean. Paleoenvironmental data were collected informing on the timing of multiple island-colonization events and land-use histories spanning the full range of human occupations in the Caribbean, from the initial forays into the islands through the arrival and eventual domination of the landscapes and indigenous people by Europeans. In some areas, our data complement archaeological, paleoecological, and historical findings from the Lesser Antilles and in others amplify understanding of colonization history. Here, we highlight data relating to the timing and process of initial colonization in the eastern Caribbean. In particular, paleoenvironmental data from Trinidad, Grenada, Martinique, and Marie-Galante (Guadeloupe) provide a basis for revisiting initial colonization models of the Caribbean. We conclude that archaeological programs addressing human occupations dating to the early to mid-Holocene, especially in dynamic coastal settings, should systematically incorporate paleoenvironmental investigations.

  15. Coastal erosion: Coast problem of the Colombian Caribbean

    International Nuclear Information System (INIS)

    The erosion promoted by the sea, affects different sectors of the coast of the Colombian Caribbean. The erosion is particularly clear in the central and western sector of the coast. The coastal problem of Punta Sabanilla - Puerto Salgar - Puerto Colombia; Pueblo Nuevo - Lomarena; Manzanillo del Mar; La Boquilla; sector Tolu - Covenas and Arboletes areas are described. This discussion is presented comform to the data obtained in field and of the revision of maps, pictures and other documents related with the coast design. The coastal erosion is not only affecting to low areas conformed by beaches, but rather this phenomenon impacts on rocky cliffs of different elevation; it is the case of El Castillo and Punta Sabanilla to Barranquilla (west Part) sectors . The causes of the setback that it experiences the coast of the Colombian Caribbean are not known in clear form; however they can be contributing such factors as: the elevation of the sea level, phenomenon that has been checked in different costs of the world; equally it can be due to a decrease in the volume of silts contributed by the Magdalena River, inside the coastal area. A third factor would be related with the diapirism of mud, that possibly would be altering the conformation of the Caribbean littoral

    Full Text Available This paper provides an analysis of the distribution patterns of marine biodiversity and summarizes the major activities of the Census of Marine Life program in the Caribbean region. The coastal Caribbean region is a large marine ecosystem (LME characterized by coral reefs, mangroves, and seagrasses, but including other environments, such as sandy beaches and rocky shores. These tropical ecosystems incorporate a high diversity of associated flora and fauna, and the nations that border the Caribbean collectively encompass a major global marine biodiversity hot spot. We analyze the state of knowledge of marine biodiversity based on the geographic distribution of georeferenced species records and regional taxonomic lists. A total of 12,046 marine species are reported in this paper for the Caribbean region. These include representatives from 31 animal phyla, two plant phyla, one group of Chromista, and three groups of Protoctista. Sampling effort has been greatest in shallow, nearshore waters, where there is relatively good coverage of species records; offshore and deep environments have been less studied. Additionally, we found that the currently accepted classification of marine ecoregions of the Caribbean did not apply for the benthic distributions of five relatively well known taxonomic groups. Coastal species richness tends to concentrate along the Antillean arc (Cuba to the southernmost Antilles and the northern coast of South America (Venezuela-Colombia, while no pattern can be observed in the deep sea with the available data.

    Haliclona (Haliclona) epiphytica n.sp., a new species of seaweed-dwelling sponge of the family Chalinidae (Porifera, Demospongiae, Haplosclerida) from the Colombian Caribbean, is described. As the only member of the subgenus Haliclona (hitherto referred to as the ‘oculata’ group by De Weerdt, 1989) in the Caribbean Sea, it is distinguished from other chalinid species in this area by its regular, anisotropic, ladder-like skeleton of short and robust oxeas.

  4. Defining and dividing the greater Caribbean: insights from the biogeography of shorefishes.

    Full Text Available The Greater Caribbean biogeographic region is the high-diversity heart of the Tropical West Atlantic, one of four global centers of tropical marine biodiversity. The traditional view of the Greater Caribbean is that it is limited to the Caribbean, West Indies, southwest Gulf of Mexico and tip of Florida, and that, due to its faunal homogeneity, lacks major provincial subdivisions. In this scenario the northern 2/3 of the Gulf of Mexico and southeastern USA represent a separate temperate, "Carolinian" biogeographic region. We completed a comprehensive re-assessment of the biogeography of the Greater Caribbean by comparing the distributions of 1,559 shorefish species within 45 sections of shelf waters of the Greater Caribbean and adjacent areas. This analysis shows that that the Greater Caribbean occupies a much larger area than usually thought, extending south to at least Guyana, and north to encompass the entire Carolinian area. Rather than being homogenous, the Greater Caribbean is divided into three major provinces, each with a distinctive, primarily tropical fauna: (1 a central, tropical province comprising the West Indies, Bermuda and Central America; (2 a southern, upwelling-affected province spanning the entire continental shelf of northern South America; and (iii a northern, subtropical province that includes all of the Gulf of Mexico, Florida and southeastern USA. This three-province pattern holds for both reef- and soft bottom fishes, indicating a general response by demersal fishes to major variation in provincial shelf environments. Such environmental differences include latitudinal variation in sea temperature, availability of major habitats (coral reefs, soft bottom shorelines, and mangroves, and nutrient additions from upwelling areas and large rivers. The three-province arrangement of the Greater Caribbean broadly resembles and has a similar environmental basis to the provincial arrangement of its sister biogeographic region, the

    Saharan dust is transported across the Atlantic and interacts with the Caribbean seasonal climatic conditions, becoming respirable and contributing to asthma presentments at the emergency department. This study investigated the relationships among dust, climatic variables, and asthma-related visits to the emergency room in Grenada. All asthma visits to the emergency room ( n = 4411) over 5 years (2001-2005) were compared to the dust cover and climatic variables for the corresponding period. Variation in asthma was associated with change in dust concentration ( R 2 = 0.036, p population sizes, industrialization level, and economies. Therefore, different than from the studies in Trinidad and Barbados, Grenada is a non-industrialized low-income small island without major industrialized air pollution addition; asthma visits were inversely related to mean sea level pressure ( R 2 = 0.123, p = 0.006) and positively correlated with relative humidity ( R 2 = 0.593, p = 0.85). Saharan dust in conjunction with seasonal humidity allows for inhalable particulate matter that exacerbates asthma among residents in the Caribbean island of Grenada. These findings contribute evidence suggesting a broader public health impact from Saharan dust. Thus, this research may inform strategic planning of resource allocation among the Caribbean public health agencies.

  8. Cenozoic Methane-Seep Faunas of the Caribbean Region.

    Steffen Kiel

    Full Text Available We report new examples of Cenozoic cold-seep communities from Colombia, Cuba, the Dominican Republic, Trinidad, and Venezuela, and attempt to improve the stratigraphic dating of Cenozoic Caribbean seep communities using strontium isotope stratigraphy. Two seep faunas are distinguished in Barbados: the late Eocene mudstone-hosted 'Joes River fauna' consists mainly of large lucinid bivalves and tall abyssochrysoid gastropods, and the early Miocene carbonate-hosted 'Bath Cliffs fauna' containing the vesicomyid Pleurophopsis, the mytilid Bathymodiolus and small gastropods. Two new Oligocene seep communities from the Sinú River basin in Colombia consist of lucinid bivalves including Elongatolucina, thyasirid and solemyid bivalves, and Pleurophopsis. A new early Miocene seep community from Cuba includes Pleurophopsis and the large lucinid Meganodontia. Strontium isotope stratigraphy suggests an Eocene age for the Cuban Elmira asphalt mine seep community, making it the oldest in the Caribbean region. A new basal Pliocene seep fauna from the Dominican Republic is characterized by the large lucinid Anodontia (Pegophysema. In Trinidad we distinguish two types of seep faunas: the mudstone-hosted Godineau River fauna consisting mainly of lucinid bivalves, and the limestone-hosted Freeman's Bay fauna consisting chiefly of Pleurophopsis, Bathymodiolus, and small gastropods; they are all dated as late Miocene. Four new seep communities of Oligocene to Miocene age are reported from Venezuela. They consist mainly of large globular lucinid bivalves including Meganodontia, and moderately sized vesicomyid bivalves. After the late Miocene many large and typical 'Cenozoic' lucinid genera disappeared from the Caribbean seeps and are today known only from the central Indo-Pacific Ocean. We speculate that the increasingly oligotrophic conditions in the Caribbean Sea after the closure of the Isthmus of Panama in the Pliocene may have been unfavorable for such large

De ces différents usages naît la question suivante : les algues sont-elles une ressource marine à exploiter pour développer durablement les territoires de la zone intertropicale ? Nous présenterons tout d’abord l’algoculture à l’échelle mondiale en soulignant le faible poids de cette activité dans le bassin caribéen. Puis nous montrerons que l’algoculture s’inscrit dans un processus de développement durable en assurant un revenu à des communautés rurales (Petites Antilles.

    Full Text Available The vulnerability of the sea urchin Diadema antillarum to the impact of the category 5 hurricane "Dean" was assessed at a back-reef area of Mahahual (Southern Mexican Caribbean. Seventy days after Dean, there was a high mean Diadema population density of 12.6 ± 4.3 (SD; from here forward ind m-2, with a large mean individual test diameter of 59.2 ±9.8 mm. This population was comparable to a previous report for the same area, just before the landfall of Dean on 21 August 2007. Immigration of adults from deeper fore-reef sites after Dean across the reef-crest was unlikely, considering the homing behavior displayed by tagged urchins. The degree of physical alteration of the habitat indicated that Diadema may survive higher hurricane-generated disturbances than those reported in previous works. These results have strong implications on the conservation of the Mexican Caribbean coral reefs since the Diadema populations surveyed have a high grazing activity and are persistent against hurricanes impact.La vulnerabilidad del erizo de mar Diadema antillarum al impacto del huracán categoría 5 "Dean" fue evaluada en el arrecife posterior de Mahahual, México. Setenta días después de la recalada de Dean fue estimada una alta densidad media poblacional de Diadema de 12.6 ind m-2 (DE = 4.3, con un elevado tamaño individual promedio de 59.2 mm de diámetro (DE = 9.8. Esta densidad fue comparable a la de un reporte previo para la misma zona, días antes del paso de Dean el 21 de agosto de 2007. Considerando la fidelidad al refugio mostrado por erizos marcados, la inmigración de adultos desde el arrecife anterior después del paso de Dean fue poco factible. El nivel de destrucción del hábitat indica que Diadema sería más persistente al impacto directo de huracanes que lo sugerido por estudios anteriores.

    EU diplomats consider the Caribbean countries to be allies and therefore expect these countries to support the EU in international affairs – but they find that this support has been waning in recent years. Caribbean diplomats and politicians do not share the European viewpoint. Rather, they take ...... the view that the EU has forgotten its Caribbean allies and instead channels its attention and funding towards Sub-Saharan Africa. This article examines to what extent this asserted ‘rift’ really signals a profound change in the EU-Caribbean relations....

His effort is “to explore the horizons for different approaches to social living in Jamaica and the Caribbean in the twenty-first century” (p. 2. In this, he “seeks to move beyond a statement of general principles to propose specific alternatives” in order to “stimulate a conversation that looks beyond the horizon of policy confines, yet is not so far removed as to appear hopelessly utopian” (p. 3. My hope with this essay is to advance that conversation, in the first place by reviewing and assessing Meeks’s contribution and then by extending the discussion to the role that Jamaica’s diaspora (and by extension that of the region’s generally might play in moving the country, as Meeks puts it, from its current “state of crime and murder, and the broad undermining of the rule of law that pervades the society” (p. 71.

    Barbados, St. Vincent, and St. Lucia have joined forces in the world's 1st regional Contraceptive Social Marketing (CSM) effort -- the Caribbean CSM. The Barbados Family Planning Association (BFPS) is overseeing the operation, which begins selling 2 contraceptive pills and a condom in early February. Costs and start-up times were shaved by adopting brand names and advertising materials from Jamaica's highly successful CSM project. Jamaica's popular "Panther" condom and "Perle" oral contraceptive (OC) are being used by the Caribbean CSM project. Perle's 9-year-old package has been redesigned and the Caribbean CSM project also is selling a 2nd, low-dose version called "Perle-LD." The products are manufactured in the US by Syntex as Noriday and Norminest, respectively. But the regional approach's financial gains also had a debit side, most notably a tripling of bureaucratic procedures. Part of project difficulties stem from differences among the 3 Caribbean countries. While sharing a common cultural heritage, St. Lucians speak a patois dialect in addition to the English prevalent on the other islands. The biggest hurdle was overcoming an economic disparity between Barbados and its less affluent neighbors, St. Vincent and St. Lucia. The CSM project decided to try a 2-tier product pricing strategy. In US currency, prices run $1.75 per cycle for both OCs on Barbados, but $1.26 on St. Vincent and St. Lucia. A Panther 3-pack costs 75 cents on Barbados and 42 cents on the othe 2 islands. The project is being promoted with generic family planning media advertisements. The project also has held physician orientation seminars on each island.

    An international team of scientists from government agencies and universities in the United States, U.S. Virgin Islands (USVI), Trinidad & Tobago, the Republic of Cape Verde, and the Republic of Mali (West Africa) is working together to elucidate the role Saharan dust may play in the degradation of Caribbean ecosystems. The first step has been to identify and quantify the persistent organic pollutants (POPs), trace metals, and viable microorganisms in the atmosphere in dust source areas of West Africa, and in dust episodes at downwind sites in the eastern Atlantic (Cape Verde) and the Caribbean (USVI and Trinidad & Tobago). Preliminary findings show that air samples from Mali contain a greater number of pesticides, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) and in higher concentrations than the Caribbean sites. Overall, POP concentrations were similar in USVI and Trinidad samples. Trace metal concentrations were found to be similar to crustal composition with slight enrichment of lead in Mali. To date, hundreds of cultureable microorganisms have been identified from Mali, Cape Verde, USVI, and Trinidad air samples. The sea fan pathogen, Aspergillus sydowii, has been identified in soil from Mali and in air samples from dust events in the Caribbean. We have shown that air samples from a dust-source region contain orders of magnitude more cultureable microorganisms per volume than air samples from dust events in the Caribbean, which in turn contain 3-to 4-fold more cultureable microbes than during non-dust conditions.

    Full Text Available The status of marine turtles in Montserrat (Eastern Caribbean is reviewed following five years of monitoring (1999-2003. The mean number of nests recorded during the annual nesting season (June-October was 53 (± 24.9 SD; range: 13-43. In accordance with earlier reports, the nesting of hawksbill (Eretmochelys imbricata and green (Chelonia mydas turtles was confirmed on several beaches around the island. Only non-nesting emergences were documented for loggerhead turtles (Caretta caretta and there was no evidence of nesting by leatherback turtles (Dermochelys coriacea; however, it is possible that additional survey effort would reveal low density nesting by these species. Officially reported turtle capture data for 1993-2003 suggest that a mean of 0.9 turtle per year (±1.2 SD; range: 0-4 were landed island-wide, with all harvest having occurred during the annual open season (1 October to 31 May. Informed observers believe that the harvest is significantly under-reported and that fishermen avoid declaring their catch by butchering turtles at sea (both during and outside the open season. Of concern is the fact that breeding adults are potentially included in the harvest, and that the open season partially coincides with the breeding season. The present study has shown that although Montserrat is not a major nesting site for sea turtles, it remains important on a regional basis for the Eastern Caribbean.

    UNAVCO manages the construction of two large NSF-funded networks of geophysical instruments in Central America and the Caribbean. COCONet (Continuously Operating Caribbean Observational Network), which consists of 83 new and refurbished cGNSS/Met stations, spans the entire Caribbean region. TLALOCNet (Trans-boundary Land and Atmospheric Long-term Observational and Collaborative Network) is a similar 24-station in Mexico. Data are being used to study solid earth processes such as plate kinematics, plate boundary deformation, and the earthquake cycle; in addition, by providing more precise estimates of tropospheric water vapor to better forecast the dynamics associated with the annual Caribbean hurricane cycle and the North American monsoon, they also address atmospheric science objectives. COCONet and TLALOCNet rely on the concept of building partnerships with a range of stakeholders that support a common goal of providing free, high-quality, low-latency, open-format data and data products. As part of COCONet, UNAVCO completed installation of sea level monitoring instruments at two locations in the Caribbean Basin. Additionally, two existing sea level stations were upgraded with co-located GNSS hardware. The locations (Jamaica, Mexico, Panama, and the Dominican Republic) enhance the coverage of tide gauge instrumentation in the Caribbean region. Each station consists of tide gauge instruments (radar and pressure gauge) on a marine pier co-located with a cGNSS/Met system. A second cGNSS system is installed nearby (Mexico and the Caribbean.

In 2005, the sea surface temperature (SST) anomaly in the tropical North Atlantic that may have contributed to the strong hurricane season caused widespread coral bleaching in the Eastern Caribbean. Here, we use two global climate models to evaluate the ...

    Centropomidae and Serranidae, sometimes collectively misnamed "sea basses", are suitable for aquaculture in pens, ponds, and raceways around the tropical and subtropical latitudes of the world. Western Atlantic Ocean species were recently considered for farming. South Florida, Mexico, Central and South America and the Antilles areas of the Caribbean Basin have extensive areas suitable for farming groupers and snook. Principal species of interest are the common snook (Centropomus undecimalis )...

    1994-12-01

    The Caribbean Expanded Program on Immunization (EPI) Managers held their 11th meeting in November 1994. The meeting attracted over 80 attendees from all of the member countries, including Puerto Rico (for the first time), representatives of nongovernmental organizations, and technical personnel. Among the achievements cited were the facts that no cases of indigenous measles have been reported in over 3 years in the Caribbean, no cases of paralytic poliomyelitis have been detected in nearly 12 years, progress has been made in the surveillance of fever and rash illnesses, and immunization coverage levels remain high. The main objectives of the meeting were to review the overall EPI program in the Caribbean in order to identify obstacles to achieving program targets and to evaluate continued efforts towards the elimination of measles by 1995. The discussions about measles focused on 1) the surveillance system for the detection of suspected cases, which has improved, but which could be strengthened and 2) the levels of immunization coverage and the continued increase in the number of children who remain susceptible to the disease (each country projected the number of children under age 5 years who would be susceptible by June 1995). Steps to maintain the polio-free status of the area, including maintaining immunization levels of at least 80%, were also reviewed. In addition, concerns about reducing the number of cases of congenital rubella syndrome were addressed with several recommendations including improving active hospital surveillance and developing an appropriate rubella vaccination strategy. Incidence rates for tuberculosis were reported, and the problems of coinfection with HIV and the emergence of drug resistant strains of the disease were discussed. Tuberculosis control programs in the region are generally inadequate, treatment standards have not been implemented, the availability of drugs is limited, and treatment monitoring is not routine.

    We present a database of published and new relative sea-level (RSL) data for the past 13 ka, which constrains the Holocene sea-level histories of the Caribbean coast of Central and South America (Florida Keys, USA to Guyana) and the Bahamas and Greater and Lesser Antilles islands. Our evaluation of mangrove peat and Acropora palmata sea-level indicators from geological investigations provides 503 sea-level index points and 242 limiting dates. We subdivide the database into 21 regions based on the availability of data, tectonic setting, and distance from the former Laurentide ice sheet. Most index points (75%) and limiting dates (90%) are <8 ka, although there is an unusual temporal distribution with the greatest amount of the data (~28%) occurring between 6-8 ka. We reassess and screen radiocarbon and U/Th ages of mangrove peat and coral data. We use the stratigraphic position (overburden thickness) of index points account for sediment compaction, and use the paleotidal model of Hill et al. (2011) to account for Holocene changes in paleotidal range. A noisy-input Gaussian process regression model calculates that the rates of RSL change were highest during the early Holocene (3-8 mm/yr) and have decreased over time (< 2 mm/yr), which is related to the reduction of ice equivalent meltwater input and collapse of the proglacial forebulge during the Holocene. The sea-level reconstructions demonstrate that RSL did not exceed the present height (0 m) during the Holocene in the majority of locations, with the exception of a small highstand (<2 m) on the northern coast of South America along the Orinoco Delta and Suriname/Guyana located furthest away from the former Laurentide Ice Sheet. The different sea-level histories are an ongoing isostatic response to deglaciation of the Laurentide Ice Sheet and suggest subsidence resulting from collapse of the proglacial forebulge reaches further south than previously considered.

  11. 8.2 ky event associated with high precipitation in the eastern Caribbean

    2013-12-01

    We present data from speleothems collected in Venezuela and Puerto Rico showing that the eastern Caribbean was anomalously moist during the 8.2ka event. Evidence from high-resolution analyses of Greenland ice core (GISP2) shows that at the same time northern Europe and the north Atlantic were cooler by 3 - 6° C. The trigger for the 8.2ka event is thought to be pulsed meltwater discharges from a multi-event drainage of proglacial lakes associated with the decaying Laurentide Ice Sheet margin. The meltwater apparently slowed the thermohaline circulation decreasing warmth to northern Europe. At the same time moisture transfer to the northern latitudes may have slowed resulting in the observed lower latitude precipitation patterns. The eastern Caribbean seems to be especially sensitive to the changes in the strength of the Atlantic meridional overturning circulation (AMOC). Higher precipitation values may also have increased lowland flooding along the coastal areas of north eastern South America, already affected by early Holocene sea-level change, and are linked to social territory reshuffling which stimulated the earliest migrations into the Caribbean Archipelago shortly afterwards. Our age models based on precise MC-ICPMS 230Th/U-dating indicate that the eastern Caribbean stalagmites all grew at about the same rate of 15 cm through the 8.2 ka event, much faster than during any other growth period, except today when they are also growing at an accelerated rate.

    Full Text Available The benthic and demersal communities in the Colombian Caribbean Sea (CCS are heavily fished by the shrimp trawling fishery, which presents very high discard levels. Here, we conducted an analysis of the size structure of these benthic and demersal communities in the northern and southern zones of the CCS. Sampling was conducted onboard shrimp trawlers throughout an entire year. No significant differences were found in the size distributions of the two zones, among sites within southern ecoregions, or among the analyzed cruises. This homogeneity in size structure is remarkable since the zones analyzed possess very different species compositions and environmental conditions. The observed size structures were adequately described by non-linear distributions rather than the traditionally employed linear normalized biomass size spectra. It is hypothesized that the non-linearity is due to the effect of fishing and particularly, of discarding. This study emphasizes the need for a greater understanding of the impacts that trawl fishing has on community size structure and the applicability of this knowledge towards fishery resource management in ecosystems with high diversity.Las comunidades bentónico-demersales en el Mar Caribe de Colombia (MCC son fuertemente explotadas por la pesca de arrastre camaronero, presentando niveles de descarte muy altos.

    The southwestern corner of the Caribbean Sea is considered a coastal warm pool oceanographically linked to the Panama Colombia Gyre. The atmosphere - ocean variability there is influenced by the Intertropical Convergence Zone (ITZC), the Andean river runoff, the northeasterly trade winds, and a tropical low level jet (San Andrés jet), all of them connected to global variability. This warm pool has a significant (>95%) warming trend (0.6°C between 1981 and 2000), with the warmest record just in front of the Sinu River, where Isla Fuerte is located, 11 km from the coast, to the western of Sinu Delta. Sea surface temperature (SST) and the Multivariate ENSO index have a significant (>95%) correlation of 0.4 with a 7 months lag. The Sinu River flow does not show a long trend between 1985 and 2000, but has a significant correlation with ENSO (0.5) with no lag. Two corals from Isla Fuerte, a Siderastrea siderea colony with a maximum length of 72.5 cm and a Montastrea annularis colony of 30.5 cm, were studied in order to test the climatic potential of these records and to understand the oceanographic variability at the SW Caribbean. Fluorescence has better resolution than density bands in both corals. Chronology based on them indicates an age of 127 and 32 years respectively. We present and discuss growth and Sr/Ca series. The signal is produced by the interaction between the river flow and local winds. The river reaches the island when northeastern winds deflect their plume to the east. However, there are not in situ instrumental records for calibration and interpretation of the signals and we used world data bases with low spatial resolution.

    Over 75 tsunamis have been documented in the Caribbean and adjacent regions during the past 500 years. Since 1500, at least 4484 people are reported to have perished in these killer waves. Hundreds of thousands are currently threatened along the Caribbean coastlines. Were a great tsunamigenic earthquake to occur in the Caribbean region today, the effects would potentially be catastrophic due to an increasingly vulnerable region that has seen significant population increases in the past 40–50 years and currently hosts an estimated 500,000 daily beach visitors from North America and Europe, a majority of whom are not likely aware of tsunami and earthquake hazards. Following the magnitude 9.1 Sumatra–Andaman Islands earthquake of 26 December 2004, the United Nations Educational, Scientific and Cultural Organization (UNESCO) Intergovernmental Coordination Group (ICG) for the Tsunami and other Coastal Hazards Early Warning System for the Caribbean and Adjacent Regions (CARIBE‐EWS) was established and developed minimum performance standards for the detection and analysis of earthquakes. In this study, we model earthquake‐magnitude detection threshold and P‐wave detection time and demonstrate that the requirements established by the UNESCO ICG CARIBE‐EWS are met with 100% of the network operating. We demonstrate that earthquake‐monitoring performance in the Caribbean Sea region has improved significantly in the past decade as the number of real‐time seismic stations available to the National Oceanic and Atmospheric Administration tsunami warning centers have increased. We also identify weaknesses in the current international network and provide guidance for selecting the optimal distribution of seismic stations contributed from existing real‐time broadband national networks in the region.

    Full Text Available Here we reconstruct seasonality and interannual to multidecadal variability of sea surface hydrology of the southern Caribbean Sea by applying paired coral Sr/Ca and δ18O measurements on fossil annually-banded Diploria strigosa corals from Bonaire. This allows for better understanding short-term (i.e., seasonal to multidecadal variability of the Caribbean hydrological cycle during the mid- to late Holocene. The monthly-resolved coral Δ δ18O records are used as a proxy for the oxygen isotopic composition of seawater (δ18Osw of the southern Caribbean Sea. Consistent with modern day conditions, annual δ18Osw cycles reconstructed from three modern corals reveal that freshwater budget at the study site is influenced by both the evaporation/precipitation ratio and the seasonal advection of tropical freshwater brought by wind-driven surface currents. In contrast, the annual δ18Osw cycle reconstructed from a mid-Holocene coral indicates sharp peaks towards more negative values in summer suggesting intense summer precipitation at 6 ka before present (BP. In line with this our model simulations indicate that increased seasonality of the hydrological cycle at 6 ka BP results from enhanced precipitation in summertime. On interannual to multidecadal timescales, the systematic positive correlation observed between reconstructed sea surface temperature and salinity suggests that freshwater discharged from the Orinoco and Amazon rivers and transported into the Caribbean by wind-driven surface currents is a critical component influencing sea surface hydrology on these timescales.

    Full Text Available The northeastern Caribbean Sea is under the seasonal influence of the Trade Winds but also of the Orinoco/Amazon freshwater plume. The latter is responsible for intensification of the Caribbean Current in general and of its eddy activity in the northern part of the Caribbean Sea. More importantly, we show in this study that the front of the freshwater plume drives a northward flow that impinges directly on the island of St. Croix in the United States Virgin Islands. The angle of incidence of the incoming flow controls the nature of the wake on both sides and ends of the island, which changes from cyclonic to anticylonic wake flow, with either attached or shed eddies. Using an off-line bio-physical model, we simulated the dispersal and recruitment of an abundant Caribbean coral reef fish, the bluehead wrasse (Thalassoma bifasciatum in the context of the wake flow variability around St. Croix. Our results revealed the role played by the consistent seasonal forcing of the wake flow on the recruitment patterns around the island at the interannual scale. The interannual variability of the timing of arrival and northward penetration of the plume instead controls the nature of the wake, hence the regional spatial recruitment patterns.

    1998-01-01

    This theoretical study of feminism in the Caribbean opens by presenting the contemporary image of the Caribbean and then pointing to the continuing influence of the colonial past in the creation of contemporary community and the establishment of identity. The paper continues with a focus on three aspects of identity, or difference, that have influenced the daily articulation of feminism and academic debates. The first concerns the positions taken by women in the region's political struggles. The second is an exploration of the linguistic meanings of the gender discourse within the region. Finally, the essay examines the idea of linguistic difference in light of contemporary Western feminist views of "sexual difference" versus equality. The discussion of each of these issues is grounded in historical analysis and illustrated with specific examples. The study concludes that, in this region, feminism offers a new way to investigate the past while creating challenges and opportunities in the struggle to establish a Caribbean identity.

Amherst: University of Massachusetts Press, 1992. x + 185 pp. (Cloth US$ 25.00 Caribbean literature has been overtaken of late by the quarrels that have pitted postmodernists against modernists in Europe and North America for the past twenty years. The modernists, faced with the fragmentation of the region that hard-nosed pragmatists and empiricists could only see as hostile to the emergence of any common culture, had sought in myth and its literary derivatives the collective impulse to transcend the divisions wrought by colonial history. Fifteen years ago I wrote a book that combined in its lead title the terms Modernism and Negritude in an effort to account for the efforts by mid-century Caribbean writers to come to grips with this problem. A decade later I demonstrated that one of the principal Caribbean modernists, Aimé Césaire, late in his career adopted stylistic characteristics that we associate with the postmodern (Arnold 1990. The example of Césaire should not be taken to suggest that we are dealing with some sort of natural evolution of modernism toward the postmodern. In fact the two terms represent competing paradigms that organize concepts and data so differently as to offer quite divergent maps of the literary Caribbean.

For the first time earthquake impact was included in addition to expected tsunami impact. The initial message was issued by the warning centers over the established channels, while different mechanisms were then used by participants for further dissemination. The enhanced PTWC tsunami products for the Caribbean were also made available to the participants. To provide feedback on the exercise an online survey tool with 85 questions was used. The survey demonstrated satisfaction with exercise, timely receipt of bulletins and interest in the enhanced PTWC products. It also revealed that while 93% of the countries had an activation and response process, only 59% indicated that they also had an emergency response plan for tsunamis and even fewer had tsunami evacuation plans and inundation maps. Given that 80% of those surveyed indicated that CARIBE WAVE should be conducted annually, CARIBE EWS decided that the next exercise be held on March 26, 2014, instead of waiting until 2015.

    USGS Caribbean Project Team: Lind Gee, Gary Gyure, John Derr, Jack Odum, John McMillan, David Carver, Jim Allen, Susan Rhea, Don Anderson, Harley Benz Caribbean Partners: Christa von Hillebrandt-Andrade-PRSN, Juan Payero ISU-UASD,DR, Eduardo Camacho - UPAN, Panama, Lloyd Lynch - SRU,Gonzalo Cruz - UNAH,Honduras, Margaret Wiggins-Grandison - Jamaica, Judy Thomas - CERO Barbados, Sylvan McIntyre - NADMA Grenada, E. Bermingham - STRI. The magnitude-9 Sumatra-Andaman Islands earthquake of December 26, 2004, increased global awareness of the destructive hazard posed by earthquakes and tsunamis. In response to this tragedy, the US government undertook a collaborative project to improve earthquake and tsunami monitoring along a major portion of vulnerable coastal regions, in the Caribbean Sea, the Gulf of Mexico, and the Atlantic Ocean. Seismically active areas of the Caribbean Sea region pose a tsunami risk for Caribbean islands, coastal areas along the Gulf of Mexico, and the Atlantic seaboard of North America. Nearly 100 tsunamis have been reported for the Caribbean region in the past 500 years, including 14 tsunamis reported in Puerto Rico and the U.S. Virgin Islands. Partners in this project include the United States Geological Survey (USGS), the Smithsonian Institute, the National Oceanic and Aeronautic Administration (NOAA), and several partner institutions in the Caribbean region. This presentation focuses on the deployment of nine broadband seismic stations to monitor earthquake activity in the Caribbean region that are affiliated with the Global Seismograph Network (GSN). By the end of 2006, five stations were transmitting data to the USGS National Earthquake Information Service (NEIS), and regional partners through Puerto Rico seismograph network (PRSN) Earthworm systems. The following stations are currently operating: SDDR - Sabaneta Dam Dominican Republic, BBGH - Gun Hill Barbados, GRGR - Grenville, Grenada, BCIP - Barro Colorado, Panama, TGUH - Tegucigalpa

    Ott, B.; Mann, P.

    2015-12-01

    The offshore Nicaraguan Rise in the western Caribbean Sea is an approximately 500,000 km2 area of Precambrian to Late Cretaceous tectonic terranes that have been assembled during the Late Cretaceous formation of the Caribbean plate and include: 1) the Chortis block, a continental fragment; 2) the Great Arc of the Caribbean, a deformed Cretaceous arc, and 3) the Caribbean large igneous province formed in late Cretaceous time. Middle Eocene to Recent eastward motion of the Caribbean plate has been largely controlled by strike-slip faulting along the northern Caribbean plate boundary zone that bounds the northern margin of the Nicaraguan Rise. These faults reactivate older rift structures near the island of Jamaica and form the transtensional basins of the Honduran Borderlands near Honduras. Recent GPS studies suggest that small amount of intraplate motion within the current margin of error of GPS measurements (1-3 mm/yr) may occur within the center of the western Caribbean plate at the Pedro Bank fault zone and Hess Escarpment. This study uses a database of over 54,000 km of modern and vintage 2D seismic data, combined with earthquake data and results from previous GPS studies to define the active areas of inter- and intraplate fault zones in the western Caribbean. Intraplate deformation occurs along the 700-km-long Pedro Bank fault zone that traverses the center of the Nicaraguan Rise and reactivates the paleo suture zone between the Great Arc of the Caribbean and the Caribbean large igneous province. The Pedro Bank fault zone also drives active extension at the 200-km-long San Andres rift along the southwest margin of the Nicaraguan Rise. Influence of the Cocos Ridge indentor may be contributing to reactivation of faulting along the southwesternmost, active segment of the Hess Escarpment.

    The queen conch, Strombus gigas, is a marine resource of ecological and economical importance in the Caribbean region. Given its importance in this region, and the critical status of most populations, the reproductive biology of this species has been studied to support management decisions. It was from these studies that a generalized sporozoan infection was detected. This study describes the geographic distribution of a coccidian (Apicomplexa) parasite infecting the digestive gland of S. gigas throughout the Caribbean. The parasite was present in every location sampled. Based on histological analysis, the parasites from all locations are similar and appear to complete their life cycle within the digestive gland. The highest occurrence of the parasites was registered in samples from Puerto Rico (54 parasites per field) and Martinique (45 parasites per field). The lowest incidence was registered on the Mexican coast of Yucatan peninsula, at Alacranes and Chinchorro with 17 parasites per field. Data showed significant differences among sites (Kruskal Wallis H=106.957; p ≤ 0.05). The abundance of parasites found in the digestive ducts and in the faeces suggests the liberation of parasites to the environment. A gradual decrease in abundance was found from East to West of the Caribbean sea. PMID:20851703

    Assessing the impact of future climate change on North Atlantic tropical cyclone (TC) activity is of crucial societal importance, but the limited quantity and quality of observational records interferes with the skill of future TC projections. In particular, North Atlantic TC response to radiative forcing is poorly understood and creates the dominant source of uncertainty for twenty-first-century projections. Here, we study TC variability in the Caribbean during the Maunder Minimum (MM; 1645-1715 CE), a period defined by the most severe reduction in solar irradiance in documented history (1610-present). For this purpose, we combine a documentary time series of Spanish shipwrecks in the Caribbean (1495-1825 CE) with a tree-growth suppression chronology from the Florida Keys (1707-2009 CE). We find a 75% reduction in decadal-scale Caribbean TC activity during the MM, which suggests modulation of the influence of reduced solar irradiance by the cumulative effect of cool North Atlantic sea surface temperatures, El Niño-like conditions, and a negative phase of the North Atlantic Oscillation. Our results emphasize the need to enhance our understanding of the response of these oceanic and atmospheric circulation patterns to radiative forcing and climate change to improve the skill of future TC projections.

    The 8.2ky event is attributed to pronounced cooling associated with the last stages of the deglaciation of the Laurentide and Scandinavian ice sheets. The global extent of this event is not well known, but it has recently been documented in various archives even in the southern hemisphere. We present proxy data evidence from speleothems collected in Venezuela and Puerto Rico that grew during the 8.2ky event. The age models based on precise MC-ICPMS 230Th/U-dating indicate that all stalagmites grew approximately 15 cm during the event - much faster than during any other growth period. This suggests that the 8.2ky event was associated with higher than normal precipitation throughout the eastern Caribbean. Higher precipitation values could have increased lowland flooding along the coastal areas of northern South America, already affected by early Holocene sea-level change, and might be linked to social territory reshuffling which stimulated the earliest migrations into the Caribbean Archipelago shortly afterwards. The eastern Caribbean seems to be very sensitive to the changes in the strength of the Atlantic Meridional Overturning Circulation (AMOC). During the 8.2ky event, moisture transfer to the northern latitudes may have been slower resulting in the observed low-latitude precipitation patterns.

  1. The boreal winter Madden-Julian Oscillation's influence on summertime precipitation in the greater Caribbean

    2016-07-01

    Precipitation totals in the greater Caribbean are known to be affected by interannual variability. In particular, dry conditions in the spring-summer have been physically linked to the positive phase of North Atlantic Oscillation (NAO) in the literature. In this study, it was found through regression analysis that an active Madden-Julian Oscillation (MJO) in winter geographically focused over the Maritime Continent contributes to a positive NAO in March via the generation of Rossby waves in the Northern Hemisphere. Specifically, a negative Pacific-North American pattern develops in the winter and transitions to an Atlantic pattern in spring. The positive NAO is a transient feature of this evolving wave train, but a center of significant positive 200 hPa geopotential heights is entrenched over the southeast U.S. throughout the February to May time period and is manifested as high pressure at the surface. The southern flank of this system increases the speeds of the trade winds and leads to a cooling of the Caribbean sea surface temperatures and, thus, convection suppression and reduced precipitation. Thus, this study advances our understanding of the climate of the greater Caribbean by using climate teleconnections to relate the MJO to rainfall in the region.

    Interdisciplinary dialog and collaboration aimed at protecting health against climate change is impeded by the small number of scientists and health professionals skilled in interdisciplinary work, and by the view held by many that "climate change won't affect me personally". These challenges may be surmounted by discussions about the lived experience of climate change and how this threatens things we value. Dialog between bioethics and public health generated an innovative collaboration using the focus group method. The main limitation of focus groups is the small number of participants however the data obtained is generalizable to wider groups and is used regularly in business to enhance marketing strategies. Caribbean academicians from varied disciplines discussed how climate change affects them and life in the Caribbean. Caribbean states are particularly vulnerable to climate change because their large coastal areas are directly exposed to rising sea levels and their development relies heavily on foreign aid. The Caribbean comprises about half of the 39 members of the Association of Small Island States (AOSIS), and small island states comprise about 5% of global population [1]. Participants described socioeconomic and environmental changes in the Caribbean that they attribute to climate change. These include extreme weather, unusual rain and drought, drying rivers, beach erosion, declining fish catches, and others. The session exposed impacts on individuals, businesses, agriculture, and disaster preparedness. This data helps to reframe climate change as a personal reality rather than a vague future concern. It is relevant to the design, implementation, and sustainability of climate policies in the Caribbean and perhaps other small island states. The method and interdisciplinary approach can be used in other settings to elicit dialog about experiences and values across sectors, and to inform policies. Those who have experienced extreme weather are more concerned

    Following the catastrophic loss of life from the December 26, 2004, Sumatra-Andaman Islands earthquake and tsunami, the U.S. Government appropriated funds to improve monitoring along a major portion of vulnerable coastal regions in the Caribbean Sea, the Gulf of Mexico, and the Atlantic Ocean. Partners in this project include the United States Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the Puerto Rico Seismic Network (PRSN), the Seismic Research Unit of the University of the West Indies, and other collaborating institutions in the Caribbean region. As part of this effort, the USGS is coordinating with Caribbean host nations to design and deploy nine new broadband and strong-motion seismic stations. The instrumentation consists of an STS-2 seismometer, an Episensor accelerometer, and a Q330 high resolution digitizer. Six stations are currently transmitting data to the USGS National Earthquake Information Center, where the data are redistributed to the NOAA's Tsunami Warning Centers, regional monitoring partners, and the IRIS Data Management Center. Operating stations include: Isla Barro Colorado, Panama; Gun Hill Barbados; Grenville, Grenada; Guantanamo Bay, Cuba; Sabaneta Dam, Dominican Republic; and Tegucigalpa, Honduras. Three additional stations in Barbuda, Grand Turks, and Jamaica will be completed during the fall of 2007. These nine stations are affiliates of the Global Seismographic Network (GSN) and complement existing GSN stations as well as regional stations. The new seismic stations improve azimuthal coverage, increase network density, and provide on-scale recording throughout the region. Complementary to this network, NOAA has placed Deep-ocean Assessment and Reporting of Tsunami (DART) stations at sites in regions with a history of generating destructive tsunamis. Recently, NOAA completed deployment of 7 DART stations off the coasts of Montauk Pt, NY; Charleston, SC; Miami, FL; San Juan, Puerto Rico; New

    St. Thomas, St. John, Tortola, and Virgin Gorda are the four main islands (lower left to upper right) of this map-view anaglyph of the U.S. Virgin Islands and British Virgin Islands, along the northeast perimeter of the Caribbean Sea. For this view, a nearly cloud-free Landsat image was draped over elevation data from the Shuttle Radar Topography Mission (SRTM), and shading derived from the SRTM data was added to enhance the topographic expression. Coral reefs fringe the islands in many locations and appear as bright patterns in near-shore waters. Tropical vegetation appears fairly dark with smooth tones, as compared to the brighter speckled patterns of towns and other developments.As in much of the world, topography is the primary factor in the pattern of land use development in the Virgin Islands. Topography across most of the islands is quite rugged, and although the steep slopes create a scenic setting, they crowd most development into the small areas of low relief terrain, generally along the shoreline. The topographic pattern also affects water supply, wastewater disposal, landfill locations, road construction, and most other features of the development infrastructure. Topography also defines the natural drainage pattern, which is the major consideration in anticipating tropical storm water runoff dangers, as well as the dangers of heightened sediment impacts upon the adjacent coral reefs.Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and substantially helps in analyzing the large and growing Landsat image archive.Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on February 11, 2000. The mission used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar that flew twice on the Space Shuttle Endeavour in 1994. The

    Climatic change threatens the future of coral reefs in the Caribbean and the important ecosystem services they provide. We used a simulation model [Combo ("COral Mortality and Bleaching Output")] to estimate future coral cover in the part of the eastern Caribbean impacted by a massive coral bleaching event in 2005. Combo calculates impacts of future climate change on coral reefs by combining impacts from long-term changes in average sea surface temperature (SST) and ocean acidification with impacts from episodic high temperature mortality (bleaching) events. We used mortality and heat dose data from the 2005 bleaching event to select historic temperature datasets, to use as a baseline for running Combo under different future climate scenarios and sets of assumptions. Results suggest a bleak future for coral reefs in the eastern Caribbean. For three different emissions scenarios from the Intergovernmental Panel on Climate Change (IPCC; B1, A1B, and A1FI), coral cover on most Caribbean reefs is projected to drop below 5% by the year 2035, if future mortality rates are equivalent to some of those observed in the 2005 event (50%). For a scenario where corals gain an additional 1-1. 5??C of heat tolerance through a shift in the algae that live in the coral tissue, coral cover above 5% is prolonged until 2065. Additional impacts such as storms or anthropogenic damage could result in declines in coral cover even faster than those projected here. These results suggest the need to identify and preserve the locations that are likely to have a higher resiliency to bleaching to save as many remnant populations of corals as possible in the face of projected wide-spread coral loss. ?? 2011 The Author(s).

  6. Why was there increased moisture in the eastern Caribbean when Europe was cold? Evidence from Speleothems

    2014-05-01

    We present evidence for the last 10,000 years from speleothems collected from the eastern Caribbean showing that this region was anomalously moist at the same time that Europe and the north Atlantic were unusually cold. The most noticeable period for this association was during the 8.2ka event when Greenland ice cores (GISP2) show that northern Europe and the north Atlantic were cooler by 3 - 6 deg C. The trigger for the 8.2ka event is thought to be pulsed melt water discharges from a multi-event drainage of proglacial lakes associated with the decaying Laurentide Ice Sheet margin. The melt water apparently slowed the thermohaline circulation decreasing warmth to northern Europe. At the same time moisture transfer to the northern latitudes may have slowed resulting in the observed lower latitude precipitation patterns. The eastern Caribbean seems to be especially sensitive to the changes in the strength of the Atlantic meridional overturning circulation (AMOC). Higher precipitation values may also have increased lowland flooding along the coastal areas of north eastern South America, already affected by early Holocene sea-level change, and are linked to social territory reshuffling which stimulated the earliest migrations into the Caribbean Archipelago shortly afterwards. Our age models based on precise MC ICPMS 230ThU dating indicate that the eastern Caribbean stalagmites all grew at about the same rate of 15 cm through the 8.2ka event, much faster than during any other growth period, except today when they are also growing at an accelerated rate.

    Rifts form in many different tectonic environments where the lithosphere is put into extension. An outline is provided of the distribution, orientation, and relative ages of 16 Cenozoic rifts along the northern edge of the Caribbean plate and it is suggested that these structures formed successively by localized extension as the Caribbean plate moved eastward past a continental promontory of North America. Evidence leading to this conclusion includes (1) recognition that the rifts become progressively younger westward; (2) a two-phase subsidence history in a rift exposed by upthrusting in Jamaica; (3) the absence of rifts east of Jamaica; and (4) the observation that removal of 1400 km of strike-slip displacement on the Cayman Trough fault system places the Paleogene rifts of Jamaica in an active area of extension south of Yucatan where the rifts of Honduras and Guatemala are forming today.

    Recent changes in the strategy of the Caribbean Contraceptive Social Marketing Project emphasize the condom, under the brand name, Panther. Since 1984, CCSMP began marketing their Perle rand of oral contraceptive, since dropped, in Barbados, St. Vincent and St. Lucia. Now wider commercial connections are envisioned, with support by CCSMP to promote generic brands. The Panther condom campaign will include an array of mass media, point-of-purchase and sporting event advertising. Pharmacies report that Panther is selling as well as the leading commercial brand. CCSMP is looking to introduce an ultra-thin condom and a vaginal foaming tablet. Market research, involving physicians and users as well as retail audits, indicates that although population in numbers alone is not a serious problem in the Caribbean, early pregnancy is a concern in the area.

    1995-12-01

    The impact is examined of socioeconomic factors on Caribbean population dynamics. This work begins by describing the socioeconomic context of the late 1980s and early 1990s, under the influence of the economic changes and crises of the 1980s. The small size, openness, dependency, and lack of diversification of the Caribbean economies have made them vulnerable to external pressures. The Bahamas and Belize had economic growth rates exceeding 5% annually during 1981-90, but most of the countries had low or negative growth. Unemployment, poverty, the structural adjustment measures adopted in the mid-1980s, and declines in social spending exacerbated general economic conditions. In broad terms, the population situation of the Caribbean is marked by diversity of sizes and growth rates. A few countries oriented toward services and tourism had demographic growth rates exceeding 3%, while at least 7 had almost no growth or negative growth. Population growth rates reflected different combinations of natural increase and migration. Crude death rates ranged from around 5/1000 to 11/1000, except in Haiti, and all countries of the region except Haiti had life expectancies of 70 years or higher. Despite fertility decline, the average crude birth rate was still relatively high at 26/1000, and the rate of natural increase was 1.8% annually for the region. Nearly half of the regional population was under 15 or over 65 years old. The body of this work provides greater detail on mortality patterns, variations by sex, infant mortality, causes of death, and implications for policy. The discussion of fertility includes general patterns and trends, age specific fertility rates, contraceptive prevalence, levels of adolescent fertility and age factors in adolescent sexual behavior, characteristics of adolescent unions, contraceptive usage, health and social consequences of adolescent childbearing, and the search for solutions.

    1985-01-01

    Five plate reconstructions with paleogeography show the evolution of the Gulf of Mexico-Caribbean-Atlantic from Late Triassic through Late Jurassic time. The reconstructions are constrained by oceanic geophysical data, by the distribution of Paleozoic tectonic belts and early Mesozoic sedimentary and igneous rocks, and by restoration of post-Jurassic faulting. Late Triassic rifting formed grabens in which continental sediments and tholeiitic volcanics accumulated. Overlying salt was deposited from ingression of Tethyan waters into circum-Atlantic grabens. Oceanic crust formed in the Atlantic about 165 m.y. ago, followed by a spreading-center jump about 160 m.y. ago. The NA/SA-Africa plate boundary was a zone of intracontinental faulting from the left-lateral Bahama fracture zone to a zone of normal and strike-slip faulting in the Gulf, to the left-lateral Mojave-Sonora megashear. Sea-floor spread in began in the proto-Caribbean in the middle Jurassic, while only rifting occurred in the Gulf of Mexico, where the Louann salt was deposited from Pacific waters. In the late Jurassic, steepening of the Pacific subduction zone resulted ion back-arc extension in Mexico. At the same time, sea-floor spreading began in the Gulf of Mexico, resulting in marine transgression. In the late Oxfordian, spreading center reorganization occurred in the Gulf. Movement ceased on the Mojave-Sonora megashear and began on the Salina Cruz right-lateral fault. In latest Jurassic spreading ceased in the Gulf, but continued in the proto-Caribbean.

Post event assessments of global coastline vulnerability highlighted the Caribbean as a region of high hazard and risk and that it was poorly monitored. Nearly 100 tsunamis have been reported for the Caribbean region and Adjacent Regions in the past 500 years and continue to pose a threat for its nations, coastal areas along the Gulf of Mexico, and the Atlantic seaboard of North and South America. Significant efforts to improve monitoring capabilities have been undertaken since this time including an expansion of the United States Geological Survey (USGS) Global Seismographic Network (GSN) (McNamara et al., 2006) and establishment of the United Nations Educational, Scientific and Cultural Organization (UNESCO) Intergovernmental Coordination Group (ICG) for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (CARIBE EWS). The minimum performance standards it recommended for initial earthquake locations include: 1) Earthquake detection within 1 minute, 2) Minimum magnitude threshold = M4.5, and 3) Initial hypocenter error of seismic network capability, we can optimize the distribution of ICG-Caribe EWS seismic stations and select an international network that will be contributed from existing real-time broadband national networks in the region. Sea level monitoring improvements both offshore and along the coast will also be addressed. With the support of Member States and other countries and organizations it has been possible to significantly expand the sea level network thus reducing the amount of time it now takes to verify tsunamis.

    Deeper coral reefs experience reduced temperatures and light and are often shielded from localized anthropogenic stressors such as pollution and fishing. The deep reef refugia hypothesis posits that light-dependent stony coral species at deeper depths are buffered from thermal stress and will avoid bleaching-related mass mortalities caused by increasing sea surface temperatures under climate change. This hypothesis has not been tested because data collection on deeper coral reefs is difficult. Here we show that deeper (mesophotic) reefs, 30-75 m depth, in the Caribbean are not refugia because they have lower bleaching threshold temperatures than shallow reefs. Over two thermal stress events, mesophotic reef bleaching was driven by a bleaching threshold that declines 0.26 °C every +10 m depth. Thus, the main premise of the deep reef refugia hypothesis that cooler environments are protective is incorrect; any increase in temperatures above the local mean warmest conditions can lead to thermal stress and bleaching. Thus, relatively cooler temperatures can no longer be considered a de facto refugium for corals and it is likely that many deeper coral reefs are as vulnerable to climate change as shallow water reefs.

    ``Mesoscale'' eddies are large whirlpools in the ocean with diameters of hundreds of kilometers. Their influence can extend to depths of 1000 m or greater. Oceanographers are only now beginning to document the prevalence, extent, and influence of such features in the world ocean. The availability of third-generation ocean color imagery from the Moderate Resolution Imaging Spectroradiometer-MODIS sensors aboard NASA's AQUA and TERRA platforms, and support for direct observation at sea, have now allowed characterization of such an eddy interacting with the Orinoco River plume (ORP) while traversing the eastern Caribbean basin. The ORP extends seasonally across the basin from August through November, 3 to 4 months after the peak of the seasonal rains across northeastern South America. At this time, a thin plume of relatively low-salinity water, rich in phytoplankton and bearing significant amounts of colored dissolved organic matter (CDOM), covers a large swath of the basin, offering a striking contrast to the intensely blue oceanic waters of the adjacent northwest Atlantic Ocean.

    The Caribbean region results from a complex tectonic history governed by the interplay of the North American, South American and (Paleo-)Pacific plates, between which the Caribbean plate evolved since the early Cretaceous. During its entire tectonic evolution, the Caribbean plate was largely surrounded by subduction and transform boundaries, which hampers a quantitative integration into the global circuit of plate motions. In addition, reconstructions of the region have so far not resulted in a first order kinematic description of the main tectonic units in terms of Euler poles and finite rotation angles. Here, we present an updated, quantitatively described kinematic reconstruction of the Caribbean region back to 200 Ma integrated into the global plate circuit, and implemented with GPlates free software. Our analysis of Caribbean tectonic evolution incorporates an extensive literature review. To constrain the Caribbean plate motion between the American continents, we use a novel approach that takes structural geological observations rather than marine magnetic anomalies as prime input, and uses regionally extensive metamorphic and magmatic phenomena such as the Great Arc of the Caribbean, the Caribbean Large Igneous Province (CLIP) and the Caribbean high-pressure belt as correlation markers. The resulting model restores the Caribbean plate back along the Cayman Trough and major strike-slip faults in Guatemala, offshore Nicaragua, offshore Belize and along the Northern Andes towards its position of origin, west of the North and South American continents in early Cretaceous time. We provide the paleomagnetic reference frame for the Caribbean region by rotating the Global Apparent Polar Wander Path into coordinates of the Caribbean plate interior, Cuba, and the Chortis Block. We conclude that a plate kinematic scenario for a Panthalassa/Pacific origin of Caribbean lithosphere leads to a much simpler explanation than a Proto-Caribbean/Atlantic origin. Placing our

    Caribbean reefs changed profoundly in taxonomic composition, diversity, and dominance structure during late Pliocene and Pleistocene climatic change. These changes coincide with protracted climatic deterioration and cooling between 2.0 to 0.8 Ma, and the onset of high amplitude sea-level fluctuations ~400 ka. The Dominican Republic Drilling Project (DRDP) was initiated to determine how climate change and global high-amplitude sea level changes influenced depositional patterns in Pliocene to Recent reef systems of the Caribbean. A transect of 7 core borings (~700 m total depth) were collected along the southern coast of the DR. New age constraints based on U/Th geochronometry and radiogenic Sr isotopes, combined with depositional lithofacies, faunal indicators, and stable isotope profiles have allowed us to correlate between wells and define the internal anatomy and stratal geometry of the individual reef sigmoids and sigmoid sets. Faunal records suggest most extinction occurred prior to ~1 Ma. Following this extinction, fringing reef margins of the Caribbean display a characteristic zonation in which Acropora palmata dominates shallow high-energy reef crests and Acropora cervicornis calmer fore-reef slopes and backreef lagoons. The dominance of acroporids across this zonation has been attributed to growth rates 5-100 times faster than other corals.

    The beauty and diversity of the Caribbean region result from geological and atmospheric processes that also pose serious threats to the large population within reach of seismic faults, hurricanes tracks, or sea-level change. The capacity to understand, prepare for, adapt to, and in some cases predict these natural hazards requires Earth observations on both large and small scales. The COCONet project was funded by the National Science Foundation (NSF) with the aim of developing a large-scale geodetic and atmospheric infrastructure in the Caribbean that will form the backbone for a broad range of geoscience and atmospheric investigations and enable research on process-oriented science questions with direct relevance to geohazards. COCONet will consist of 50 new GPS and meteorological stations throughout the Caribbean region, 15 existing stations refurbished with new receivers, antennas, and meteorological instruments, and will also incorporate data from up to 61 existing operational GPS stations. Additional funding has recently been allocated to install 2 new collocated GPS and tide gauge sites and also add GPS instruments at two existing tide gauge sites in the Caribbean region. COCONet will provide free, high-quality, low-latency, open-format data and data products for researchers, educators, students, and the private sector. Data will be used by US and international scientists to study solid earth processes such as plate kinematics and dynamics as well as plate boundary interactions and deformation, with an emphasis on the earthquake cycle. COCNet will also serve atmospheric science objectives by providing more precise estimates of tropospheric water vapor and enabling better forecast of the dynamics of airborne moisture associated with the yearly Caribbean hurricane cycle. COCONet is being installed and will be maintained by UNAVCO on behalf of the science and other user communities in the United States and abroad, thus leveraging UNAVCO's proven record of

    Full Text Available Abstract:This paper examines one important dimension of the European Union's (EU 'regional' engagement with the Caribbean: its relations with the Overseas Countries and Territories (OCT, with a particular focus on the possibility of furthering the policy goals of greater regional integration and cooperation. It does so in three parts. The first sets out the basis for current EU policy to the OCT which has been under discussion between the EU, the OCT and the four EU member states most involved (Denmark, France, the Netherlands and the United Kingdom since 2008. It reports EU proposals for change and the responses to them by the Caribbean OCTs. The second part examines EU policy toward promoting greater regional cooperation among the Caribbean OCTs and between them and some of the other Caribbean regional organizations. Three distinct frameworks for cooperation and integration are discussed: with independent states as established in the Caribbean Community, the Caribbean Forum and the Economic Partnership Agreement; with the French departments and collectivities; and with the Caribbean OCT. In each the position of the Caribbean OCT is situated. The final part briefly discusses the creation of a 'new' framework for regional cooperation specific for the Caribbean OCT which will most closely match their interests in the Caribbean.Resumen: La Unión Europea y la Región del Caribe: Situando a los Países y Territorios de Ultramar del CaribeEste ensayo analiza una dimensión importante de la Unión Europea (UE 'regional' y su compromiso con el Caribe: de igual manera sus relaciones con los Países y Territorios de Ultramar (PTU, con un enfoque particular sobre la posibilidad de promover los objetivos de la política con una mayor integración regional y cooperación.

  12. Water Security and Services in the Caribbean

    2014-05-01

    Full Text Available The efficient management of water resources and services continues to be a concern in many of the small island states of the Caribbean. There are growing concerns over the ability of governments in the region to ensure the good management and provision of water without jeopardizing economic growth and the maintenance of social well-being. This paper provides an overview of the major factors influencing the water security facing the Caribbean Region and how the emerging concerns are being addressed. The key challenges and vulnerabilities may be summarized as lack of data and barriers to making available what information there is. Forward planning has been largely neglected and is symptomatic of a lack of appreciation of the need for having national water policies. In this respect Jamaica’s development of a national master water plan serves as a good example of what is needed. Water service providers have to be efficient, well managed and allowed to do their job. This means that they have to be on a sound financial footing. The challenge is to find the balance between appropriate political and regulatory oversight and the autonomy of water managers and service providers.

    vigorously communicate results in simple and straightforward terms to foster more effective conservation and management. This and subsequent reports will focus on separate biogeographic regions in a stepwise fashion and combine all of the results for a global synthesis in the coming years. We began in the wide Caribbean region because the historical data are so extensive and to refine methods of analysis before moving on to other regions. This report documents quantitative trends for Caribbean reef corals, macroalgae, sea urchins, and fishes based on data from 90 reef locations over the past 43 tears. This is the first report to combine all these disparate kinds of data in a single place to explore how the different major components of coral reef ecosystems interact on a broadly regional oceanic scale. We obtained data from more than 35,000 ecological surveys carried out by 78 principal investigators (PIs) and some 200 colleagues working in 34 countries, states, and territories throughout the wide Caribbean region. We conducted two workshops in Panama and Brisbane, Australia to bring together people who provided the data to assist in data quality control, analysis, and synthesis. The first workshop at the Smithsonian Tropical Research Institute (STRI) in the Republic of Panama 29 April to 5 May, 2012 included scientists from 18 countries and territories to verify and expand the database and to conduct exploratory analyses of status and trends. Preliminary results based on the Panama workshop were presented to the DC Marine Community and Smithsonian Institution Senate of Scientists in May 2012 and at the International Coral Reef Symposium (ICRS) and annual ICRI meeting in Cairns, Australia in July 2012. The second workshop in Brisbane, Australia in December 2012 brought together eight coral reef scientists for more detailed data analysis and organization of results for this report and subsequent publications.

    Many cnidarians host endosymbiotic dinoflagellates from the genus Symbiodinium. It is generally assumed that the symbiosis is mutualistic, where the host benefits from symbiont photosynthesis while providing protection and photosynthetic substrates. Diverse assemblages of symbiotic gorgonian octocorals can be found in hard bottom communities throughout the Caribbean. While current research has focused on the phylo- and population genetics of gorgonian symbiont types and their photo-physiology, relatively less work has focused on biogeochemical benefits conferred to the host and how these benefits vary across host species. Here we examine this symbiosis among 11 gorgonian species collected in Bocas del Toro, Panama. By coupling light and dark bottle incubations (P/R) with (13)C-bicarbonate tracers, we quantified the link between holobiont oxygen metabolism with carbon assimilation and translocation from symbiont to host. Our data show that P/R varied among species, and was correlated with colony morphology and polyp size. Sea fans and sea plumes were net autotrophs (P/R>1.5), while nine species of sea rods were net heterotrophs with most below compensation (P/Rcoral bleaching, whereas generalist and facultative associations are common among sea rods that have higher bleaching sensitivities. Overall, productivity and polyp size had strong phylogenetic signals with carbon fixation and polyp size showing evidence of trait covariance. PMID:25989369

    This August 2014, a 14-day expedition of the E/V NAUTILUS of the OCEAN EXPLORATION TRUST will explore the region delimited by two deep straits of the northern Caribbean, the Windward passage and the Jamaica Channel. The morphology of these straits is controlled by two transform faults: The Septentrional fault, which stretches between Cuba and Haiti (slip rate: ~13 mm/yr), and the Enriquillo-Plantain Garden Fault (EPGF), which stretches between Jamaica and Haiti (slip rate: ~9 mm/yr). Together, these faults bound the Gonave microplate, an elongated platelet caught between the North America plate and Caribbean plates. The Septentrional fault ruptured in 1842, devastating the town of Cap Haitien. The EPGF ruptured catastrophically in 2010 near Port-au-Prince (death toll > 100,000). Tsunamis were associated with both earthquakes. Oblique slip on these two faults is presumably controlling the history of uplift and subsidence of the seafloor, and has therefore also been regulating the water exchanges between the north central Atlantic and the Caribbean Sea. New multibeam bathymetric and CHIRP sub-bottom profiling data will be acquired with the E/V NAUTILUS, while the ROV HERCULES will be used to collect video, water and rock samples, as well as water column physical properties. We anticipate that this survey will document the following: (1) The nature of drowned carbonate platforms, which in turn may provide useful markers to assess rates of vertical deformation along the two faults. (2) The extent of major landslides detected on the steep fore reefs from existing multibeam bathymetric data. (3) Whether fluids are actively seeping along the fault traces or in association with the landslides, as has been reported elsewhere around the World. (4) If cold seeps are indeed present, to what extent their associated ecosystems are affected by the bottom currents that flow through these gateways. Altogether, the new findings should contribute to a better understanding of the

    López, Mario Monroy; Solano, Oscar David

    2005-12-01

    In order to know the current condition of the Echinometra lucunter population in the Colombian Caribbean, ten zones of the most representative rocky-shore were selected for sampling between November 2002 and May 2003. In each zone, four transects of 10.25 m2 were located parallel to the coast, and measured with a 0.25 m2 quadrant under the tide level. Two subsamples of 0.01 m2 were chosen from each quadrant, in order to determine the sea urchin heights and its associated fauna. This species was found in nine of the selected zones where the rocky-shore was of sedimentary origin and was absent in Punta Gloria because of the igneous origin of the rock, that the sea urchins cannot bore. The greatest average densities were obtained in Zapsurro and Inca Inca with 69 and 65 ind/m2 respectively; these are high values for the Caribbean Sea, whereas Acandi and Punta Betin had the lowest because of continental water discharges. The most frequent test diameter was between 25 and 40 mm (smaller on the western zones). The density of E. lucunter and of its associated fauna (including the endemic Ophiothrix synoecina) in the Santa Marta area decreased in the last decade.

    2016-01-01

    Coral reefs are declining worldwide due to multiple factors including rising sea surface temperature, ocean acidification, and disease outbreaks. Over the last 30 years, White Band Disease (WBD) alone has killed up to 95% of the Caribbean`s dominant shallow-water corals--the staghorn coral Acropora cervicornis and the elkhorn coral A. palmata. Both corals are now listed on the US Endangered Species Act, and while their recovery has been slow, recent transmission surveys indicate that more than 5% of staghorn corals are disease resistant. Here we compared transcriptome-wide gene expression between resistant and susceptible staghorn corals exposed to WBD using in situ transmission assays. We identified constitutive gene expression differences underlying disease resistance that are independent from the immune response associated with disease exposure. Genes involved in RNA interference-mediated gene silencing, including Argonaute were up-regulated in resistant corals, whereas heat shock proteins (HSPs) were down-regulated. Up-regulation of Argonaute proteins indicates that post-transcriptional gene silencing plays a key, but previously unsuspected role in coral immunity and disease resistance. Constitutive expression of HSPs has been linked to thermal resilience in other Acropora corals, suggesting that the down-regulation of HSPs in disease resistant staghorn corals may confer a dual benefit of thermal resilience.

  5. Caribbean area food irradiation feasibility study

    International Nuclear Information System (INIS)

    The US Agency for International Development funded the Caribbean Area Food Irradiation Feasibility Study (CAFI) through the US National Food Processors Association and with the collaboration of the US Department of Energy. This study focused on the economic, technical, financial, political and social feasibility of transferring food irradiation technology to the Caribbean area. The study focuses on three areas including the benefits to small farmers and nations interested in the export of crops, including non-traditional tropical commodities. The Feasibility Study Team conducted field work in Guatemala, Haiti, and Trinidad. The benefits of irradiation technology have been shown to have an impact particularly on the small farmer who is more capable of producing non-traditional crops intended for international export marketing. In Haiti, the anthropologists working on the CAFI study found that 74,000 individuals will be directly affected by the ban on the postharvest fumigant ethylene dibromide. Irradiation technology can not only provide the quarantine security needed to allow crops requiring quarantine treatment to move into international trade, but it can promote international co-operation in technology transfer. Training and safety issues related to the transfer, operation, and disposal of nuclear materials must be considered and point out the need for adequate regional co-operative programmes. Research and training programmes will be needed to augment the implementation of food irradiation processing by the private sector. Irradiation firms planning facilities in developing countries may need to provide crop production information, international marketing intelligence, and other assistance needed to integrate an irradiator into the overall postharvest food system.

    2011-12-01

    The beauty and diversity of the Caribbean region result from geological and atmospheric processes that also pose serious threats to the large population within reach of seismic faults, hurricanes tracks, or sea-level change. The capacity to understand, prepare for, adapt to, and in some cases predict these natural hazards requires Earth observations on both large and small scales. The COCONet project was funded by the National Science Foundation (NSF) with the aim of developing a large-scale geodetic and atmospheric infrastructure in the Caribbean that will form the backbone for a broad range of geoscience and atmospheric investigations and enable research on process-oriented science questions with direct relevance to geohazards. COCONet will consist of 50 new combination GPS and meteorological stations throughout the Caribbean region, and will incorporate data from up to 65 existing GPS stations. COCONet will provide free, high-quality, low-latency, open-format data and data products for researchers, educators, students, and the private sector. These data will be used by local and foreign researchers to study solid earth processes such as plate kinematics and dynamics, and plate boundary interaction and deformation, including earthquake cycle processes. It will also serve atmospheric science objectives by providing more precise estimates of tropospheric water vapor and enabling better forecast of the dynamics of airborne moisture associated with the yearly Caribbean hurricane cycle. COCONet will be installed and maintained by UNAVCO on behalf of the science and other user communities in the United States and abroad, thus leveraging UNAVCO's proven record of efficient and effective network management and its longstanding commitment to collaborative science. Field activities for the COCONet project commenced in March, 2011. To date, field reconnaissance has been conducted at 20 locations for new stations, with formal proposals submitted to host countries and/or in

  10. Phylogenetic and morphologic analyses of a coastal fish reveals a marine biogeographic break of terrestrial origin in the southern Caribbean.

    Directory of Open Access Journals (Sweden)

    Ricardo Betancur-R

    Full Text Available BACKGROUND: Marine allopatric speciation involves interplay between intrinsic organismal properties and extrinsic factors. However, the relative contribution of each depends on the taxon under study and its geographic context. Utilizing sea catfishes in the Cathorops mapale species group, this study tests the hypothesis that both reproductive strategies conferring limited dispersal opportunities and an apparent geomorphologic barrier in the Southern Caribbean have promoted speciation in this group from a little studied area of the world. METHODOLOGY/PRINCIPAL FINDINGS: Mitochondrial gene sequences were obtained from representatives of the Cathorops mapale species group across its distributional range from Colombia to Venezuela. Morphometric and meristic analyses were also done to assess morphologic variation. Along a approximately 2000 km transect, two major lineages, Cathorops sp. and C. mapale, were identified by levels of genetic differentiation, phylogenetic reconstructions, and morphological analyses. The lineages are separated by approximately 150 km at the Santa Marta Massif (SMM in Colombia. The northward displacement of the SMM into the Caribbean in the early Pleistocene altered the geomorphology of the continental margin, ultimately disrupting the natural habitat of C. mapale. The estimated approximately 0.86 my divergence of the lineages from a common ancestor coincides with the timing of the SMM displacement at approximately 0.78 my. MAIN CONCLUSIONS/SIGNIFICANCE: Results presented here support the hypothesis that organismal properties as well as extrinsic factors lead to diversification of the Cathorops mapale group along the northern coast of South America. While a lack of pelagic larval stages and ecological specialization are forces impacting this process, the identification of the SMM as contributing to allopatric speciation in marine organisms adds to the list of recognized barriers in the Caribbean.

    Full Text Available The locality of San Francisco de Asís (Acandí, Chocó overlooking the Caribbean Sea, is a well-known headquarter for actions related to environmental protection, thanks to the work of organization and individuals that try to alleviate the global environmental crisis. The great expansion of the evangelical movement among populations that formerly were catholic puts these new local churches in a position of social actors that can contribute to the conservation projects of marine life and forests. Although there is no organic link between the conservationist movement and evangelical churches, analyzinga shared experience in the journeys of protecting marine turtles, we see how the topic gains relevance for the religious organizations, according to the ethnography realized between 2008 and 2009. Thus, religious believes cease to be contrasts to the norm, to set themselves up as dependent orientations within the context in which they operate.

    The screen of 10 soft coral extracts collected from the Colombian Caribbean Sea in the TPA-induced ear edema model allowed us to identify Eunicea fusca extract among others as an interesting source of active compounds. The new diterpene, fuscoside E (1), along with the known fuscoside B (2), fuscol (3), (+)-germacrene D (4) and a mixture of six sterols (5-10), were isolated from this soft coral. Their structures were elucidated by 1D and 2D NMR spectroscopy techniques. Fuscoside E (1) absolute stereochemistry was determined by chiroptical methods. Fuscoside E (1) and B (2) showed strong anti-inflammatory in the above mentioned bioassay. Additionally, fuscoside E (1) and the sterol mixture (5-10) presented antifouling activity against bacterial strains involved in surface colonization. PMID:21865038

    The Caribbean region is considered to be at risk for avian influenza (AI) due to a large backyard poultry system, an important commercial poultry production system, the presence of migratory birds, and disparities in the surveillance systems. The Caribbean Animal Health Network (CaribVET) has developed tools to implement AI surveillance in the region with the goals to have 1) a regionally harmonized surveillance protocol and specific web pages for AI surveillance on www.caribvet.net, and 2) an active and passive surveillance for AI in domestic and wild birds. A diagnostic network for the Caribbean, including technology transfer and AI virus molecular diagnostic capability in Guadeloupe (real-time reverse transcription-polymerase chain reaction for the AI virus matrix gene), was developed. Between 2006 and 2009, 627 samples from four Caribbean countries were tested for three circumstances: importation purposes, following a clinical suspicion of AI, or through an active survey of wild birds (mainly waders) during the southward and northward migration periods in Guadeloupe. None of the samples tested were positive, suggesting a limited role of these species in the AI virus ecology in the Caribbean. Following low pathogenic H5N2 outbreaks in the Dominican Republic in 2007, a questionnaire was developed to collect data for a risk analysis of AI spread in the region through fighting cocks. The infection pathway of the Martinique commercial poultry sector by AI, through introduction of infected cocks, was designed, and recommendations were provided to the Caribbean Veterinary Services to improve cock movement control and biosecurity measures. The CaribVET and its organization allowed interaction between diagnostic and surveillance tools on the one hand and epidemiologic studies on the other, both of them developed in congruence with regional strategies. Together, these CaribVET activities contribute to strengthening surveillance of avian influenza virus (AIV) in the

    The Working Group 2 (WG2) of the Intergovernmental Coordination Group for the Tsunami and Other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (ICG/CARIBE-EWS) in charge of Tsunami Hazards Assessment, has generated a list of tsunami sources for the Caribbean region. Simulating these worst-case, most credible scenarios would provide an estimate of the resulting effects on coastal areas within the Caribbean. In the past few years, several publications have addressed this issue resulting in a collection of potential tsunami sources and scenarios. These publications come from a wide variety of sources; from government agencies to academic institutions. Although these provide the scientific community with a list of sources and scenarios, it was the interest of the WG2 to evaluate what has been proposed and develop a comprehensive list of sources, therefore leaving aside proposed scenarios. The seismo-tectonics experts of the Caribbean within the WG2 members were tasked to evaluate comprehensively which published sources are credible, worst-cases, and consider other sources that have been omitted from available reports. Among these published sources are the GEM Faulted Earth Subduction Characterization Project, and the LANTEX/Caribe Wave annual exercise publications (2009-2015). Caribbean tectonic features capable of generating tsunamis from seismic dislocation are located along the Northeastern Caribbean, the Lesser Antilles Trench, and the Panamá and Southern Caribbean Deformed Belts. The proposed sources have been evaluated based on historical and instrumental seismicity as well as geological and geophysical studies. This paper presents the sources and their justification as most-probable tsunami sources based on the context of crustal deformation due to Caribbean plate interacting with neighboring North and South America plates. Simulations of these sources is part of a subsequent phase in which effects of these tectonically induced tsunamis

    International Nuclear Information System (INIS)

    To develop this document we have placed our eagerness to present an analysis of the Energy Sector of Latin American and Caribbean, it contains information about the current energy situation of each of our member countries, regional data, as well as economic and social indicators corrected through historical series. The 2003 energy report, presents an innovative structure for analysis that allows the reader to easily find general information on the energy sectors of the 26th OLADE member countries. In addition, the written publications present data from Algeria, an extra regional participant country of the Organization. With the objective of enriching the statistical value that the document have presented since initial editions, this document contains the participation of our technical coordinators in the each of our specialized areas of our organization: energy policy, hydrocarbons, electricity, statistical information, renewable energy and environment. It is likely to emphasize in this occasion, for the first time the energy report is spread into the immediate year subsequent to the one of reference, as it was obtained thanks to the effort of our specialists and the cooperation of our countries members. The modern world presents us with constant changes and challenges for the security of supply that sets dynamic integration within the strategic areas. In this sense, we expect that this document will be a useful tool to face the challenges of the energy sector of our region. (The author)

    Dr. Sharla Blank

    2013-06-01

    Full Text Available This paper presents a broad overview of historical and contemporary gender and social class relations in the British, French, and Spanish Caribbean islands focusing primarily on Afro-Caribbean people. It begins with a discussion of gendered relations during slavery and then investigates gender roles post emancipation. Next, multiple aspects of contemporary West Indian family life are addressed including the prevalence of matrifocal households and child shifting. The important roles played by Caribbean female household heads are discussed in the context of patriarchy. Highlights include the significance of the maternal role over the marital, socializing youth, particular negative expectations each sex holds of the other, customary sexual behavior, as well as common relationship types. Varying aspects of women’s behavior according to social class is touched upon followed by a brief synopsis of the status of Caribbean women on measures of educational and work force participation rates; finally, a summary of the dearth of active women’s movements in the region is addressed. The paper provides an introduction to the intimate and working lives of Caribbean women and men.

    Politicians do not acknowledge the devastating impacts riverine sediments can have on healthy coral reef ecosystems during environmental debates in Caribbean countries. Therefore, regional and/or local decision makers do not implement the necessary measures to reduce fluvial sediment fluxes on coral reefs. The Magdalena River, the main contributor of continental fluxes into the Caribbean Sea, delivers water and sediment fluxes into the Rosario Islands National Park, an important marine protected area in the southwestern Caribbean. Until now, there is no scientific consensus on the presence of sediment fluxes from the Magdalena River in the coral reefs of the Rosario Islands. Our hypothesis is that high sediment and freshwater inputs from the Magdalena have been present at higher acute levels during the last decade than previously thought, and that these runoff pulses are not flashy. We use in-situ calibrated MODIS satellite images to capture the spatiotemporal variability of the distribution of suspended sediment over the coral reefs. Furthermore, geochemical data are analyzed to detect associated sedimentation rates and pollutant dispersion into the coastal zone. Results confirm that turbidity levels have been much higher than previous values presented by national environmental authorities on coral reefs off Colombia over the last decade. During the 2003-2013-period most of the Total Suspended Sediments (TSS) values witnessed in the sampled regions were above 10mg/l, a threshold value of turbidity for healthy coral reef waters. TSS concentrations throughout the analyzed time were up to 62.3mg/l. Plume pulses were more pronounced during wet seasons of La Niña events in 2002-2003, 2007-2008, and 2009-2010. Reconstructed time series of MODIS TSS indicates that coral reef waters were exposed to river plumes between 19.6 and 47.8% of the entire period of analysis (2000-2013).

    As shown by the recent Mw 7.0 Haiti earthquake, intra-arc deformation, which accompanies the subduction process, can present seismic and tsunami hazards to nearby islands. Spatially-limited diffuse tectonic deformation within the Northeast Caribbean Plate Boundary Zone likely led to the development of the submerged Mona Passage between Puerto Rico and the Dominican Republic. GPS geodetic data and a moderate to high level of seismicity indicate that extension within the region is ongoing. Newly-collected high-resolution multibeam bathymetry and multi-channel seismic reflection profiles and previously-collected samples are used here to determine the tectonic evolution of the Mona Passage intra-arc region. The passage is floored almost completely by Oligocene-Pliocene carbonate platform strata, which have undergone submarine and subaerial erosion. Structurally, the passage is characterized by W- to NNW-trending normal faults that offset the entire thickness of the Oligo-Pliocene carbonate platform rocks. The orientation of these faults is compatible with the NE-oriented extension vector observed in GPS data. Fault geometry best fits an oblique extension model rather than previously proposed single-phase, poly-phase, bending-moment, or rotation extension models. The intersection of these generally NW-trending faults in Mona Passage with the N-S oriented faults of Mona Canyon may reflect differing responses of the brittle upper-crust, along an arc-forearc rheological boundary, to oblique subduction along the Puerto Rico trench. Several faults within the passage, if ruptured completely, are long enough to generate earthquakes with magnitudes on the order of Mw 6.5-7. ?? 2010.

    In this article, we review recent research on mental health in the Caribbean. Three major themes emerge: (a) the effects of colonialism on the Caribbean psyche; (b) decolonization of psychiatric public policy, including innovative treatment approaches, deinstitutionalization, and community and policy responses to mental health issues; and (c) the nature and epidemiology of psychiatric pathology among contemporary Caribbean people, with particular focus on migration, genetic versus social causation of psychosis and personality disorders, and mechanisms of resilience and social capital. Caribbean transcultural psychiatry illustrates the principles of equipoise unique to developing countries that protect the wellness and continued survival of postcolonial Caribbean people.

    Full Text Available This study considers and compares several of the most important factors contributing to coastal flooding in Latin American and the Caribbean (LAC while accounting for the variations of these factors with location and time. The study assesses the populations, the land areas and the built capital exposed at present and at the middle and end of the 21st century for a set of scenarios that include both climatic and non-climatic drivers. Climatic drivers include global mean sea level, natural modes of climate variability such as El Niño, natural subsidence, and extreme sea levels resulting from the combination of projected local sea-level rise, storm surges and wave setup. Population is the only human-related driver accounted for in the future. Without adaptation, more than 4 million inhabitants will be exposed to flooding from relative sea-level rise by the end of the century, assuming the 8.5 W m-2 trajectory of the Representative Concentration Pathways (RCPs, or RCP8.5. However, the contributions from El Niño events substantially raise the threat in several Pacific-coast countries of the region and sooner than previously anticipated. At the tropical Pacific coastlines, the exposure by the mid-century for an event similar to El Niño 1998 would be comparable to that of the RCP4.5 relative sea-level rise by the end of the century. Furthermore, more than 7.5 million inhabitants, 42,600 km2 and built capital valued at 334 billion USD are currently situated at elevations below the 100-year extreme sea level. With sea levels rising and the population increasing, it is estimated that more than 9 million inhabitants will be exposed by the end of the century for either of the RCPs considered. The spatial distribution of exposure and the comparison of scenarios and timeframes can serve as a guide in future adaptation and risk reduction policies in the region.

  14. Climate-related global changes in the southern Caribbean: Trinidad and Tobago

    1997-10-01

    A climate change deriving from the atmospheric build up of greenhouse gases (GHG) is supposed to become evident by the middle of the next century. This GHG-induced climate change would supposedly lead to a global warming of about 2 to 4°C and a rise in mean sea level of about 60 cm towards the end of the next century. This study focuses on the field measurements and interpretations of a number of, supposedly, climate-driven regional changes, including shifts in climate and hydrology, coastal erosion and sedimentation, salinisation of coastal aquifers and estuaries, and also coral bleaching, in Trinidad and Tobago, in the southern Caribbean. The results show significant changes and shifts in temperature and rainfall, severe coastal erosion, approaching 2 to 4 m per year for certain beaches, appreciable salinisation of a number of coastal aquifers and an estuary along the Caroni swamp, in Trinidad, and what appears to be partial coral bleaching, at the Culloden Reef in Tobago. These field-observed regional changes may conceivably be interpreted as early signals of a GHG-induced climate change. However, in view of the uncertainty surrounding GHG-induced climate change and sea level rise and the limitations of our data, especially the length of record, caution must be exercised in the interpretation of these results.

  1. Unexpected evolutionary diversity in a recently extinct Caribbean mammal radiation

    Identifying general patterns of colonization and radiation in island faunas is often hindered by past human-caused extinctions. The insular Caribbean is one of the only complex oceanic-type island systems colonized by land mammals, but has witnessed the globally highest level of mammalian extinction during the Holocene. Using ancient DNA analysis, we reconstruct the evolutionary history of one of the Caribbean's now-extinct major mammal groups, the insular radiation of oryzomyine rice rats. Despite the significant problems of recovering DNA from prehistoric tropical archaeological material, it was possible to identify two discrete Late Miocene colonizations of the main Lesser Antillean island chain from mainland South America by oryzomyine lineages that were only distantly related. A high level of phylogenetic diversification was observed within oryzomyines across the Lesser Antilles, even between allopatric populations on the same island bank. The timing of oryzomyine colonization is closely similar to the age of several other Caribbean vertebrate taxa, suggesting that geomorphological conditions during the Late Miocene facilitated broadly simultaneous overwater waif dispersal of many South American lineages to the Lesser Antilles. These data provide an important baseline by which to further develop the Caribbean as a unique workshop for studying island evolution. PMID:25904660

  9. Dust and Air Quality Forecasting in the Eastern Caribbean

    Science.gov (United States)

    Sealy, A. M.; Reyes, A.; Farrell, D. A.

    2015-12-01

    Significant amounts of dust travel across the northern tropical Atlantic to the Caribbean every year from the Sahara region. These dust concentrations in the Caribbean often exceed United States Environmental Protection Agency (EPA) standards for particulate matter of 2.5 microns or less (PM 2.5) which could have serious implications for human health in the region. Air pollution has become a major issue in the Caribbean because of urban development, increased vehicle emissions and growing industrialisation. However, the majority of territories in the Caribbean do not have routine air quality monitoring programmes and several do not have or enforce air quality standards for PM2.5 and PM10. As a result, the Caribbean Institute for Meteorology and Hydrology (CIMH) has taken the initiative to provide dust and air quality forecasts for the Eastern Caribbean using the advanced WRF-Chem modeling system. The applications of the WRF-Chem modelling system at CIMH that are currently being focused on are the coupled weather prediction/dispersion model to simulate the release and transport of constituents, especially Saharan dust transport and concentration; and as a coupled weather/dispersion/air quality model with full interaction of chemical species with prediction of particulate matter (PM2.5 and PM10). This will include future applications in the prediction of ozone (O3) and ultraviolet (UV) radiation as well as examining dust radiative forcing and effects on atmospheric precipitation and dynamics. The simulations are currently initialised at 00Z for a seven day forecast and run at 36 km resolution with a planned second domain (at 12 km) for air quality forecasts. Preliminary results from this study will be presented and compared to other dust forecast models currently used in other regions. This work also complements in situ measurements at Ragged Point, Barbados (oldest dust record since 1965), Martinique, Guadeloupe, French Guiana and Puerto Rico. The goal of this study

    2013-12-01

    The Caribbean and Adjacent Regions has a long history of tsunamis and earthquakes. Over the past 500 years, more than 75 tsunamis have been documented in the region by the NOAA National Geophysical Data Center. Just since 1842, 3446 lives have been lost to tsunamis; this is more than in the Northeastern Pacific for the same time period. With a population of almost 160 million, over 40 million visitors a year and a heavy concentration of residents, tourists, businesses and critical infrastructure along its shores (especially in the northern and eastern Caribbean), the risk to lives and livelihoods is greater than ever before. The only way to survive a tsunami is to get out of harm's way before the waves strike. In the Caribbean given the relatively short distances from faults, potential submarine landslides and volcanoes to some of the coastlines, the tsunamis are likely to be short fused, so it is imperative that tsunami warnings be issued extremely quickly and people be educated on how to recognize and respond. Nevertheless, given that tsunamis occur infrequently as compared with hurricanes, it is a challenge for them to receive the priority they require in order to save lives when the next one strikes the region. Close cooperation among countries and territories is required for warning, but also for education and public awareness. Geographical vicinity and spoken languages need to be factored in when developing tsunami preparedness in the Caribbean, to make sure citizens receive a clear, reliable and sound science based message about the hazard and the risk. In 2006, in the wake of the Indian Ocean tsunami and after advocating without success for a Caribbean Tsunami Warning System since the mid 90's, the Intergovernmental Oceanographic Commission of UNESCO established the Intergovernmental Coordination Group for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (CARIBE EWS). Its purpose is to advance an end to end tsunami

    The coastal waters of south Florida, including the coral reefs of NOAA's Florida Keys National Marine Sanctuary (FKNMS), are directly connected by means of strong ocean currents with upstream waters of the western Caribbean Sea and the Gulf of Mexico. The Caribbean Current and the Loop Current provide a rapid conduit for transport from Mexican and Belizean coral reefs, located off the eastern shore of the Yucatan Peninsula, to nearshore regions of northern Cuba, Florida, and the Bahamas. Interdisciplinary cruise data collected in August 2002, March 2006 and January 2007 aboard the NOAA Ship Gordon Gunter, in combination with satellite-tracked surface drifter trajectories and remote sensing imagery, clearly show the highly variable and dynamic nature of the regional current regimes and provide a means of quantifying the potential pathways and transport rates of the coastal waters and their biological and chemical constituents from one region to another. Results from these cruises and ancillary data show that the study areas are connected with rapid transport time scales, and that frontal eddies and gyres play an important role in establishing the time and length scales of this connectivity. Such direct physical connectivity between the coral reef biota of these geographically separated spawning grounds via ocean currents may have an important influence on the degree of biological connectivity between regional larval populations. Initial analyses of ichthyoplankton surveys and inshore collections along the Yucatan mesoamerican reef suggest large scale variability in both local recruitment and large scale spatial distribution. Despite strong northward flowing currents, inshore collections indicate that local recruitment in some areas is strongly influenced by small scale circulation patterns. However, the distribution of spawning aggregations along the Yucatan coast suggests a larger role for the Caribbean Current. Determining the interactions between the larger scale

    New deep-penetrating high-resolution multichannel seismic reflection data collected in the eastern Caribbean during R/V Ewing cruise EW9501 imaged both the crustal structure and overlying stratigraphic successions. On the basis of this new multichannel seismic data, we define the geologic development of the Beata Ridge and Venezuelan basin. The Caribbean crust was formed by seafloor spreading in Late Jurassic Early Cretaceous time. Prior to the Senonian, widespread and rapid eruption of basaltic flows began in concert with extensional deformation of the Caribbean crust. Thick volcanic wedges characterized by divergent reflectors are observed along the boundary that separates rough from smooth oceanic crust, are coincident with an abrupt shallowing of the Moho, and appear to be bounded by a large, northwest-dipping fault system. The locus of major extensional deformation migrated through time from the Venezuelan basin to the western flank of the Beata Ridge. Extensional unloading of the Beata Ridge footwall caused uplift and rotation of the ridge. Sediment thicknesses and stratal geometry observed across the Venezuelan basin and Beata Ridge suggest that the majority of the deformation in this region occurred during and soon after the emplacement of the volcanics. Minor fault reactivation in the Neogene along the eastern flank of the Beata Ridge is associated with an accommodation zone (i.e., tear fault) that records a change in the deformation style from bending and subduction of the Caribbean plate along the Muertos Trough south of Puerto Rico to compressional deformation and obduction of the Caribbean plate south of Hispaniola. We propose that this difference in deformational style is, in part, a consequence of the thicker crust on the Beata Ridge, which is more resistant to subduction.

Unfortunately, with some notable individual exceptions, this is the same anthropology which has largely ignored the Caribbean and its "Islands of History."1 Of course, this says much, much more about the way in which anthropology constructs its subject than it says about the merits of the Caribbean case and the fundamental essence of these societies, born as they were in the unforgiving and defining moment of pervasive, persuasive, and pernicious European construction of "Otherness." As Trouillot (1992:22 writes, "Whereas anthropology prefers 'pre-contact' situations - or creates 'no-contact' situations - the Caribbean is nothing but contact." If the anthropological fiction of pristine societies, uninfluenced and uncontaminated by "outside" and more powerful structures and cultures cannot be supported for the Caribbean, then many anthropologists do one or both of the two anthropologically next best things: they take us on a journey that finds us exploding the "no-contact" myth over and over (I think it is called "strawpersonism", suddenly discovering political economy, history, and colonialism, and/or they end up constructing the "pristine" anyway by emphasizing those parts of a diaspora group's pre-Caribbean culture that are thought to remain as cultural "survivals."

  15. VOLCANIC TSUNAMI GENERATING SOURCE MECHANISMS IN THE EASTERN CARIBBEAN REGION

    Directory of Open Access Journals (Sweden)

    George Pararas-Carayannis

    2004-01-01

    Full Text Available Earthquakes, volcanic eruptions, volcanic island flank failures and underwater slides have generated numerous destructive tsunamis in the Caribbean region. Convergent, compressional and collisional tectonic activity caused primarily from the eastward movement of the Caribbean Plate in relation to the North American, Atlantic and South American Plates, is responsible for zones of subduction in the region, the formation of island arcs and the evolution of particular volcanic centers on the overlying plate. The inter-plate tectonic interaction and deformation along these marginal boundaries result in moderate seismic and volcanic events that can generate tsunamis by a number of different mechanisms. The active geo-dynamic processes have created the Lesser Antilles, an arc of small islands with volcanoes characterized by both effusive and explosive activity. Eruption mechanisms of these Caribbean volcanoes are complex and often anomalous. Collapses of lava domes often precede major eruptions, which may vary in intensity from Strombolian to Plinian. Locally catastrophic, short-period tsunami-like waves can be generated directly by lateral, direct or channelized volcanic blast episodes, or in combination with collateral air pressure perturbations, nuéss ardentes, pyroclastic flows, lahars, or cascading debris avalanches. Submarine volcanic caldera collapses can also generate locally destructive tsunami waves. Volcanoes in the Eastern Caribbean Region have unstable flanks. Destructive local tsunamis may be generated from aerial and submarine volcanic edifice mass edifice flank failures, which may be triggered by volcanic episodes, lava dome collapses, or simply by gravitational instabilities. The present report evaluates volcanic mechanisms, resulting flank failure processes and their potential for tsunami generation. More specifically, the report evaluates recent volcanic eruption mechanisms of the Soufriere Hills volcano on Montserrat, of Mt. Pel

    Episodes of mass coral bleaching around the world in recent decades have been attributed to periods of anomalously warm ocean temperatures. In 2005, the sea surface temperature (SST) anomaly in the tropical North Atlantic that may have contributed to the strong hurricane season caused widespread coral bleaching in the Eastern Caribbean. Here, the authors use two global climate models to evaluate the contribution of natural climate variability and anthropogenic forcing to the thermal stress that caused the 2005 coral bleaching event. Historical temperature data and simulations for the 1870-2000 period show that the observed warming in the region is unlikely to be due to unforced climate variability alone. Simulation of background climate variability suggests that anthropogenic warming may have increased the probability of occurrence of significant thermal stress events for corals in this region by an order of magnitude. Under scenarios of future greenhouse gas emissions, mass coral bleaching in the Eastern Caribbean may become a biannual event in 20-30 years. However, if corals and their symbionts can adapt by 1-1.5{sup o}C, such mass bleaching events may not begin to recur at potentially harmful intervals until the latter half of the century. The delay could enable more time to alter the path of greenhouse gas emissions, although long-term 'committed warming' even after stabilization of atmospheric CO{sub 2} levels may still represent an additional long-term threat to corals.

  18. The status of coral reef ecology research in the Red Sea

    2013-06-21

    The Red Sea has long been recognized as a region of high biodiversity and endemism. Despite this diversity and early history of scientific work, our understanding of the ecology of coral reefs in the Red Sea has lagged behind that of other large coral reef systems. We carried out a quantitative assessment of ISI-listed research published from the Red Sea in eight specific topics (apex predators, connectivity, coral bleaching, coral reproductive biology, herbivory, marine protected areas, non-coral invertebrates and reef-associated bacteria) and compared the amount of research conducted in the Red Sea to that from Australia\\'s Great Barrier Reef (GBR) and the Caribbean. On average, for these eight topics, the Red Sea had 1/6th the amount of research compared to the GBR and about 1/8th the amount of the Caribbean. Further, more than 50 % of the published research from the Red Sea originated from the Gulf of Aqaba, a small area (<2 % of the area of the Red Sea) in the far northern Red Sea. We summarize the general state of knowledge in these eight topics and highlight the areas of future research priorities for the Red Sea region. Notably, data that could inform science-based management approaches are badly lacking in most Red Sea countries. The Red Sea, as a geologically "young" sea located in one of the warmest regions of the world, has the potential to provide insight into pressing topics such as speciation processes as well as the capacity of reef systems and organisms to adapt to global climate change. As one of the world\\'s most biodiverse coral reef regions, the Red Sea may yet have a significant role to play in our understanding of coral reef ecology at a global scale. © 2013 Springer-Verlag Berlin Heidelberg.

  19. Patterns of deep-water coral diversity in the Caribbean Basin and adjacent southern waters: an approach based on records from the R/V Pillsbury expeditions.

    Directory of Open Access Journals (Sweden)

    Iván Hernández-Ávila

    Full Text Available The diversity of deep-water corals in the Caribbean Sea was studied using records from oceanographic expeditions performed by the R/V Pillsbury. Sampled stations were sorted according to broad depth ranges and ecoregions and were analyzed in terms of species accumulation curves, variance in the species composition and contributions to alpha, beta and gamma diversity. According to the analysis of species accumulation curves using the Chao2 estimator, more diversity occurs on the continental slope (200-2000 m depth than on the upper continental shelf (60-200 m depth. In addition to the effect of depth sampling, differences in species composition related to depth ranges were detected. However, the differences between ecoregions are dependent on depth ranges, there were fewer differences among ecoregions on the continental slope than on the upper continental shelf. Indicator species for distinctness of ecoregions were, in general, Alcyonaria and Antipatharia for the upper continental shelf, but also the scleractinians Madracis myriabilis and Cladocora debilis. In the continental slope, the alcyonarian Placogorgia and the scleractinians Stephanocyathus and Fungiacyathus were important for the distinction of ecoregions. Beta diversity was the most important component of gamma diversity in the Caribbean Basin. The contribution of ecoregions to alpha, beta and gamma diversity differed with depth range. On the upper continental shelf, the Southern Caribbean ecoregion contributed substantially to all components of diversity. In contrast, the northern ecoregions contributed substantially to the diversity of the Continental Slope. Strategies for the conservation of deep-water coral diversity in the Caribbean Basin must consider the variation between ecoregions and depth ranges.

    1966-12-16

    The first detailed paleontological analysis of a deep-sea pistoncore from the Caribbean Sea has been completed. The core, P6304-8, was raised from 3927 meters, east of Beata Ridge at 14 degrees 59'N, 69 degrees 20'W. Formerly, stratigraphic works in this area were based on studies of paleotemperature, measured by the oxygen isotope mass spectrometry method, or on micropaleontological analysis by means of rapid or cursory examinations. For core P6304-8, samples for foraminiferal analysis were taken at 10-centimeter intervals and split into smaller samples containing an average of 710 individuals (smallest sample, 517 individuals); all individuals were then identified and counted. By use of data derived from populations of this size, a statistical reliability was insured within a 5 percent limnit. Temperature oscillations, the best method of portraying Pleistocene stratigraphy, were shown by using ratios of the relative abundances of tropical and subtropical planktonic foraminifera to those found in temperate and cooler waters. These ratios correlate well with existing paleotemperature measurements for the same core, obtained by the oxygen isotope mass spectrometry method. PMID:17821563

    .S. Caribbean. Lower magnitude decreases were seen in indicator debris along the eastern Gulf of Mexico. In contrast, only land-based indicators declined in the western Gulf of Mexico; total, ocean-based and general-source indicators remained unchanged. Decreases in land-based indicators were not related to human population in the coastal regions; human population increased in all regions over the time of the study. Significant monthly patterns for indicator debris were found only in the Gulf of Mexico; counts were highest during May through September, with peaks occurring in July. Inclement weather conditions before the time of the survey also accounted for some of the variation in the western Gulf of Mexico; fewer items were found when there were heavy seas or cold fronts in the weeks prior to the survey, while tropical storms (including hurricanes) increased the amount of debris. With the development around the globe of long-term monitoring programs using standardized methodology, there is the potential to help management at individual sites, as well as generate larger-scale perspectives (from regional to global) to inform decision makers. Incorporating mechanisms producing debris into marine debris programs would be a fruitful area for future research.

    The impacts of drought in the Caribbean have not been as dramatic as in some other parts of world, but it is not exempt from the experiences of drought. As a result of the effects of a prolonged drought in 2009/2010, the agenda for the 21st Inter-Sessional Meeting of the Caribbean Community (CARICOM) paid particular attention to the issue of drought. This paper reviews the management framework for responding to drought disasters in five CARICOM countries. The paper also reports on some of the effects of the 2009/2010 drought with particular reference to Grenada and the Grenadines. During the drought in these islands there were numerous bush fires with devastating effects on agriculture, severe water shortages that impacted on the tourism industry and other social effects. It is evident that there was inadequate preparation for the event. Greater planning and investment are therefore required to reduce future impacts. PMID:25754334

    Full Text Available Tax havens have long been under the attention of numerous Governments and International Organizations which triggered the concern of an uneven playing field in the taxation area. As a result numerous amendments have been made to both their commercial and tax legislations in order to be in line with the internationally agreed tax standards. The aim of this article is to conduct a SWOT analysis on the offshore corporate structures found in the Caribbean landscape. Based on a selection process of the most commonly recognized tax havens in the Caribbean region and an analysis of their offshore companies at the level of incorporation, administration, activities conducted and costs, a set of frequently met characteristics have been identified which stand at the basis of the SWOT analysis. The results stand to present a comprehensive four dimension framework of the offshore corporate structures in regards to their strengths, weaknesses, opportunities and threats.

    The Red Sea has long been recognized as a region of high biodiversity and endemism. Despite this diversity and early history of scientific work, our understanding of the ecology of coral reefs in the Red Sea has lagged behind that of other large coral reef systems. We carried out a quantitative assessment of ISI-listed research published from the Red Sea in eight specific topics (apex predators, connectivity, coral bleaching, coral reproductive biology, herbivory, marine protected areas, non-coral invertebrates and reef-associated bacteria) and compared the amount of research conducted in the Red Sea to that from Australia's Great Barrier Reef (GBR) and the Caribbean. On average, for these eight topics, the Red Sea had 1/6th the amount of research compared to the GBR and about 1/8th the amount of the Caribbean. Further, more than 50 % of the published research from the Red Sea originated from the Gulf of Aqaba, a small area (reef systems and organisms to adapt to global climate change. As one of the world's most biodiverse coral reef regions, the Red Sea may yet have a significant role to play in our understanding of coral reef ecology at a global scale.

    The Caribbean basin is home to some of the most complex interactions in recent history among previously diverged human populations. Here, we investigate the population genetic history of this region by characterizing patterns of genome-wide variation among 330 individuals from three of the Greater Antilles (Cuba, Puerto Rico, Hispaniola), two mainland (Honduras, Colombia), and three Native South American (Yukpa, Bari, and Warao) populations. We combine these data with a unique database of genomic variation in over 3,000 individuals from diverse European, African, and Native American populations. We use local ancestry inference and tract length distributions to test different demographic scenarios for the pre- and post-colonial history of the region. We develop a novel ancestry-specific PCA (ASPCA) method to reconstruct the sub-continental origin of Native American, European, and African haplotypes from admixed genomes. We find that the most likely source of the indigenous ancestry in Caribbean islanders is a Native South American component shared among inland Amazonian tribes, Central America, and the Yucatan peninsula, suggesting extensive gene flow across the Caribbean in pre-Columbian times. We find evidence of two pulses of African migration. The first pulse—which today is reflected by shorter, older ancestry tracts—consists of a genetic component more similar to coastal West African regions involved in early stages of the trans-Atlantic slave trade. The second pulse—reflected by longer, younger tracts—is more similar to present-day West-Central African populations, supporting historical records of later transatlantic deportation. Surprisingly, we also identify a Latino-specific European component that has significantly diverged from its parental Iberian source populations, presumably as a result of small European founder population size. We demonstrate that the ancestral components in admixed genomes can be traced back to distinct sub

    Objective: To explore the emotional intelligence (EI) in medical students in a Caribbean medical school and investigate its association with gender, age, year of study and ethnicity. Design and Methods: A cross-sectional design using convenient sampling of 304 years two to five undergraduate medical students at the School of Medicine, The University of the West Indies (UWI), St Augustine campus, was conducted. The Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT-V2.0) was administered to test four branches of EI: perceiving emotions, facilitating thought, understanding emotions and managing emotions. Data were analysed using SPSS version 19. T-test, analysis of variance (ANOVA) and r (product moment correlation) were calculated to establish the effects of selected variables (gender, age, year of study and ethnicity) on total and sub-scales EI scores and tested against 0.05 and 0.01 significance levels. Results: The total mean score for EI fell within the average according to MSCEIT standards. Gender analysis showed significantly higher scores for males and for younger age groups (< 25 years). Year of study and ethnicity did not yield any significant effect. Conclusions: These findings of higher EI scores in males and younger students are unusual, given the well-publicized stereotype of the Caribbean male and the perception that advancing age brings maturity and emotional stability. It would be valuable to widen this study by including other UWI campuses and offshore medical schools in the Caribbean. This preliminary study examined a sample of medical students from a well-established Caribbean medical school. Since EI is considered to be important in the assessment and training of medical undergraduates, consideration should be given to introducing interventions aimed at increasing EI. PMID:25303251

    Full Text Available Caribbean Small Island Developing States (SIDS made good process on improving the health of their populations; but concerns exist when it comes to meeting changing health needs. Due to remoteness and limited resources it is difficult to respond to high rates of non-communicable diseases (NCDs. Furthermore, little is known about how primary care (PC is organised and how this responds to current health issues. This study focused on gaining insights in the organisation of PC of Caribbean SIDS based on currently available literature. This literature review was an explorative multiple case study, where structure of PC and health status of 16 Caribbean SIDS were reviewed using available scientific and grey literature between the years 1997 and 2014. Thirty documents were used to analyse 20 indicators for the dimensions “Structure of Primary Care” and “Health Status”. Results were mapped in order to identify if there is a possible relation between structures of PC to the health of the populations. When reviewing the structure of PC, the majority of information was available for “Economic conditions of PC” (78% and the least information was available for “Governance of PC” (40%. With regards to health status, all islands show improvements on “Life expectancy at birth” since 2007. In contrast, on average, the mortality due to NCDs did not improve. Saint Lucia performs best on “Structure of PC”. The British Virgin Islands have the best health status. When both dimensions were analysed, Saint Lucia performs best. There is still little known on the responsiveness of PC of Caribbean SIDS to NCDs. There is a need for elaborate research on: (1 If and how the functioning of these health systems relate to the health status; (2 What islands can learn from an analysis over time and what they can learn from cross-island analysis; and (3 Filling the gaps of knowledge which currently exist within this field of research.

  20. Structural and geophysical interpretation of Roatan Island, Honduras, Western Caribbean

    Science.gov (United States)

    Sutton, Daniel Scott

    Roatan Island is the largest of the Bay Islands of Honduras. These islands form an emergent crest off the Caribbean coast of Honduras called the Bonacca Ridge. The Bartlett Trough to the north and subsequent Bonacca Ridge were likely formed due to the transform fault system of the Motagua-Swan Islands Fault System. This fault system forms the tectonic plate boundary between the North American and Caribbean plates. Although the timing and kinematics are poorly constrained, the Bay Islands and the Bonacca Ridge were likely uplifted due to transpression along this left-lateral strike-slip system. With limited regional exposures along the adjacent tectonic boundary, this study aimed to present a structural interpretation for Roatan. This new interpretation is further explained through regional considerations for a suggested geologic history of the northwestern Caribbean. In order to better constrain the kinematics of uplift and exhumation of Roatan Island, structural, gravity, and magnetic surveys were conducted. Principal attention was directed to the structural relationship between the geologic units and their relationship to one another through deformation. Resulting geologic cross-sections from this study present the metamorphic basement exposed throughout the island to be in a normal structural order consisting of biotite schist and gneiss, with overlying units of chlorite schist, carbonate, and conglomerate. These units have relatively concordant strike and dip measurements, consistent with resultant magnetic survey readings. Additionally, large and irregular bodies of amphibolite and serpentinite throughout the island are interpreted to have been emplaced as mafic and ultra-mafic intrusions in weakness zones along Early Paleogene transform system fault planes. The interpretation and suggested geologic history from this study demonstrate the importance of transpressive tectonics both local to Roatan and regionally throughout geologic history. Consideration of

    Paleontologists typically treat major episodes of extinction as single and distinct events in which a major environmental perturbation results in a synchronous evolutionary response. Alternatively, the causes of biotic change may be multifaceted and extinction may lag behind the changes ultimately responsible because of nonlinear ecological dynamics. We examined these alternatives for the major episode of Caribbean extinction 2 million years ago (Ma). Isolation of the Caribbean from the Eastern Pacific by uplift of the Panamanian Isthmus was associated with synchronous changes in Caribbean near shore environments and community composition between 4.25 and 3.45 Ma. Seasonal fluctuations in Caribbean seawater temperature decreased 3-fold, carbonate deposition increased, and there was a striking, albeit patchy, shift in dominance of benthic ecosystems from heterotrophic mollusks to mixotrophic reef corals and calcareous algae. All of these changes correspond well with a simple model of decreased upwelling and collapse in planktonic productivity associated with the final stages of the closure of the isthmian barrier. However, extinction rates of mollusks and corals did not increase until 3-2 Ma and sharply peaked between 2 and 1 Ma, even though extinction overwhelmingly affected taxa commonly associated with high productivity. This time lag suggests that something other than environmental change per se was involved in extinction that does not occur as a single event. Understanding cause and effect will require more taxonomically refined analysis of the changing abundance and distribution patterns of different ecological guilds in the 2 million years leading up to the relatively sudden peak in extinction.

The three books under review here, all based on dissertation research and all published in 2009, make important contributions to this growing literature. While each one approaches sexual politics from a distinctive disciplinary, geographic, and theoretical vantage point, all three ask readers to take seriously the central place that sexual desires and practices occupy in the lives of Caribbean people, both at home and in the diaspora. Caribbean sexuality studies are still sometimes thought of as belonging to a domain outside of, or auxiliary to “real” politics, but these studies demonstrate without hesitation how sexuality functions as an important prism through which we might understand broader debates about ethics, politics, and economics in the region. Building from the insights of feminist theorists who connect the “private” realm to community, national, and global geopolitics, they show that sex is intimately connected to certain freedoms – be they market, corporeal, or political – as well as to their consequences. Taken together, they consider sexual subjectivity, political economy, and cultural production in unexpected ways and point to exciting new directions for the

  5. Latin American and Caribbean Federation of Radiation Protection Societies (FRALC)

    International Nuclear Information System (INIS)

    The idea of a Federation of Radiation Protection Societies in Latin America came up at the First Regional Congress on Radiation Protection and Nuclear Safety that was held in Buenos Aires (Argentina), in October 1991. At the Second Regional Congress, in Zacatecas (Mexico), in 1993, the Latin American and Caribbean Federation of Radiation Protection Societies (FRALC) was officially launched. The founder members were the Argentine Radiation Protection Society (SAR), the Brazilian Radiation Protection Society (SBPR), the Mexican Radiation Safety Society (SMSR) and the Peruvian Radiation Protection Society (SPR). Now, the FRALC has accepted as members the Radiation Protection Section of the Cuban Physics Society (SPRC) and the Uruguayan Radiation Protection Association (AUR). The basic objectives of the FRALC are: to promote the safe use of radiation and radioactive sources in Latin America and the Caribbean; to promote the foundation of new Radiation Protection Societies within the region, as mean of associating radiation protection professionals, and then, to promote of affiliation of this new societies to IRPA; to encourage the cooperation and mutual aid in the study, research and use of resources, in order to promote the radiation protection development in Latin America and the Caribbean

  6. Renewable power production in a Pan-Caribbean energy grid

    Science.gov (United States)

    Miller, David

    The Small Island Developing States of the Caribbean are victims of geography and geopolitics. Lacking access to large fossil fuel reserves, they are forced to import fuel at prices they have no control over. Renewable energy resources, particularly wind, have the potential to help break the Caribbean dependency on fossil fuels and allow for increased development at the same time. Working from a sustainable development point of view, this project discusses the history of the area, the theoretical background for the idea of large scale renewable power production, the regional initiatives already in place that address both the cost of fossil fuels and the policy hurdles that need to be overcome to assist the region in gaining energy independence. Haiti is highlighted as a special case in the region and the potential use of several renewable resources are discussed, along with a potential business model based on the idea of the Internet. Power storage is covered, specifically the potential of battery operated vehicles to have a positive impact on the Caribbean region and other developing states. The role of government regulation and policy comes into play next, followed by a discussion on the need for developed states to change patterns of behavior in order to achieve sustainability. Finally, nuclear power and liquefied natural gas are reviewed and rejected as power options for the region.

    The purpose of preparing this annotated bibliography was to compile information on coal localities for the Caribbean region used for preparation of a coal map of the region. Also, it serves as a brief reference list of publications for future coal studies in the Caribbean region. It is in no way an exhaustive study or complete listing of coal literature for the Caribbean. All the material was gathered from published literature with the exception of information from Cuba which was supplied from a study by Gordon Wood of the US Geological Survey, Branch of Coal Resources. Following the classification system of the US Geological Survey (Wood and others, 1983), the term coal resources has been used in this report for reference to general estimates of coal quantities even though authors of the material being annotated may have used the term coal reserves in a similar denotation. The literature ranges from 1857 to 1981. The countries listed include Colombia, Mexico, Venezuela, Cuba, the Dominican Republic, Haiti, Jamaica, Puerto Rico, and the countries of Central America.

    Full Text Available Deadly western North Atlantic Ocean tsunami events in the last centuries have occurred along the east coast of Canada, the United States, most Caribbean islands, and the North Atlantic Coast of South America. The catastrophic Indian Ocean tsunami of 2004 reminded natural hazards managers that tsunami risk is endemic to all oceans. Total Risk is defined as hazard (frequency of tsunami events times measures of elements at risk (human exposure times measures of vulnerability (preparedness in a given epoch (Nott, 2006. While the tsunami hazard in the Caribbean (averaging 19 ± 22 years between deadly events is lower than Pacific coastal areas, the total risk to life and property is at least as high as the USA West Coast, Hawaii, or Alaska, because of the higher Caribbean population density and beach tourism so attractive to more than 35 million visitors a year. Viewed in this light, the allocation of resources by governments, industry, and insurers needs to be adjusted for the better protection of life, for coastal engineering, and for infrastructure.

    In response to the Deepwater Horizon (DwH) oil spill event in 2010, the Naval Oceanographic Office deployed a nowcast-forecast system covering the Gulf of Mexico and adjacent Caribbean Sea that was designated Americas Seas, or AMSEAS, which is documented in this manuscript. The DwH disaster provided a challenge to the application of available ocean-forecast capabilities, and also generated a historically large observational dataset. AMSEAS was evaluated by four complementary efforts, each with somewhat different aims and approaches: a university research consortium within an Integrated Ocean Observing System (IOOS) testbed; a petroleum industry consortium, the Gulf of Mexico 3-D Operational Ocean Forecast System Pilot Prediction Project (GOMEX-PPP); a British Petroleum (BP) funded project at the Northern Gulf Institute in response to the oil spill; and the Navy itself. Validation metrics are presented in these different projects for water temperature and salinity profiles, sea surface wind, sea surface temperature, sea surface height, and volume transport, for different forecast time scales. The validation found certain geographic and time biases/errors, and small but systematic improvements relative to earlier regional and global modeling efforts. On the basis of these positive AMSEAS validation studies, an oil spill transport simulation was conducted using archived AMSEAS nowcasts to examine transport into the estuaries east of the Mississippi River. This effort captured the influences of Hurricane Alex and a non-tropical cyclone off the Louisiana coast, both of which pushed oil into the western Mississippi Sound, illustrating the importance of the atmospheric influence on oil spills such as DwH.

    2005-12-01

    A high resolution (3-8 km grid), 3D numerical ocean model of the West Caribbean Sea (WCS) is used to investigate the variability and the forcing of flows near the Meso-American Barrier Reef System (MBRS) which runs along the coasts of Mexico, Belize, Guatemala and Honduras. Mesoscale variations in velocity and temperature along the reef were found in seasonal model simulations and in observations; these variations are associated with meandering of the Caribbean current (CC) and the propagation of Caribbean eddies. Diagnostic calculations and a simple assimilation technique are combined to infer the dynamically adjusted flow associated with particular eddies. The results demonstrate that when a cyclonic eddy (negative sea surface height anomaly (SSHA)) is found near the MBRS the CC shifts offshore, the cyclonic circulation in the Gulf of Honduras (GOH) intensifies, and a strong southward flow results along the reef. However, when an anticyclonic eddy (positive SSHA) is found near the reef, the CC moves onshore and the flow is predominantly westward across the reef. The model results help to explain how drifters are able to propagate in a direction opposite to the mean circulation when eddies cause a reversal of the coastal circulation. The effect of including the Meso-American Lagoon west of the Belize Reef in the model topography was also investigated, to show the importance of having accurate coastal topography in determining the variations of transports across the MBRS. The variations found in transports across the MBRS (on seasonal and mesoscale time scales) may have important consequences for biological activities along the reef such as spawning aggregations; better understanding the nature of these variations will help ongoing efforts in coral reef conservation and maintaining the health of the ecosystem in the region.

    There has been an increase in the scale and frequency of coral bleaching around the world due mainly to changes in sea temperature. This may occur at large scales, often resulting in significant decline in coral coverage. In order to understand the molecular and cellular basis of the ever-increasing incidence of coral bleaching, we have undertaken a comparative proteomic approach with the endangered Caribbean coral Acropora palmata. Using a proteomic tandem mass spectrometry approach, we identified 285 and 321 expressed protein signatures in bleached and unbleached A. palmata colonies, respectively, in southwestern Puerto Rico. Overall the expression level of 38 key proteins was significantly different between bleached and unbleached corals. A wide range of proteins was detected and categorized, including transcription factors involved mainly in heat stress/UV responses, immunity, apoptosis, biomineralization, the cytoskeleton, and endo-exophagocytosis. The results suggest that for bleached A. palmata, there was an induced differential protein expression response compared with those colonies that did not bleach under the same environmental conditions.

    Full Text Available Abstract Background The Caribbean region, like other developing regions of the world, faces significant challenges in conducting research, especially in the context of limited resource capacities and capabilities. Further, due to its diverse and multiple island states, research capacity is scattered and unevenly spread within the region. The Caribbean EcoHealth Programme (CEHP is a research program that is structured to improve the capacity and capability of health professionals in the Caribbean region to respond in integrative and innovative ways to on-going and emerging environmental health challenges by means of multi-sectoral interventions. Methods Core parts of the CEHP’s mission are to (1 conduct collaborative research in areas that the region has identified as critical; (2 build and strengthening integrated approaches to research; and (3 develop and enhance basic research capacity within the Caribbean region. Fundamental to the success of the CEHP’s human and resource development mission has been its use of the Atlantis Mobile Laboratory (AML. The AML has allowed the CEHP program to move throughout the Caribbean and be able to respond to calls for specific research and capacity building opportunities. Results The CEHP’s five main research projects have generated the following results: (1 the Persistent Organic Pollutants (POPs study has evaluated human exposures to POPs, heavy metals, pesticides, and zoonotic infections; (2 the Burden of Illness (BOI studies have developed protocols for the testing of foodborne microorganisms, strengthen laboratory analytical capabilities, and determined the prevalence and incidence of food-borne illness; (3 the Rainwater Harvesting (RWH study has evaluated the microbial and chemical quality of rainwater harvesting systems; (4 the Ecotoxicology Water (ETW studies have provided much needed data on the quality of recreational and drinking water supplies, and (5 the Food Safety Training Program has

    investigate whether predictions of mantle structure from tectonic reconstructions are in agreement with a detailed tomographic image of seismic P wave velocity structure under the Caribbean region. In the upper mantle, positive seismic anomalies are imaged under the Lesser Antilles and Puerto Rico. These anomalies are interpreted as remnants of Atlantic lithosphere subduction and confirm tectonic reconstructions that suggest at least 1100 km of convergence at the Lesser Antilles island arc during the past ~45 Myr. The imaged Lesser Antilles slab consists of a northern and southern anomaly, separated by a low-velocity anomaly across most of the upper mantle, which we interpret as the subducted North America-South America plate boundary. The southern edge of the imaged Lesser Antilles slab agrees with vertical tearing of South America lithosphere. The northern Lesser Antilles slab is continuous with the Puerto Rico slab along the northeastern plate boundary. This results in an amphitheater-shaped slab, and it is interpreted as westward subducting North America lithosphere that remained attached to the surface along the northeastern boundary of the Caribbean plate. At the Muertos Trough, however, material is imaged until a depth of only 100 km, suggesting a small amount of subduction. The location and length of the imaged South Caribbean slab agrees with proposed subduction of Caribbean lithosphere under the northern South America plate. An anomaly related to proposed Oligocene subduction at the Nicaragua rise is absent in the tomographic model. Beneath Panama, a subduction window exists across the upper mantle, which is related to the cessation of subduction of the Nazca plate under Panama since 9.5 Ma and possibly the preceding subduction of the extinct Cocos-Nazca spreading center. In the lower mantle, two large anomaly patterns are imaged. The westernmost anomaly agrees with the subduction of Farallon lithosphere. The second lower mantle anomaly is found east of

    Mineral dust is an important component of the atmosphere and the climate system since mineral dust acts as cloud condensation nuclei (CCN) as well as ice nuclei (IN) and contributes significantly to the global annual particle emissions by mass. Every year, huge amounts of Saharan mineral dust is transported westward across the Atlantic Ocean into the Caribbean. During transport, the chemical and microphysical properties of the mineral dust may be modified thereby changing the CCN properties of the dust aerosol. During the Saharan Aerosol Long-range Transport and Aerosol-Cloud-Interaction Experiment (SALTRACE: http://www.pa.op.dlr.de/saltrace) in June/July 2013, CCN measurements were performed on the DLR Falcon research aircraft with a dual column Cloud Condensation Nuclei Counter (CCNC) first at Cape Verde then at the Caribbean. The CCNC provides information about concentration of CCN at two different supersaturations at the same time. For SALTRACE, one column of the CCNC was set to 0.2% supersaturation, whereas the second column was operated in scanning mode at different supersaturations between 0.1 and 0.5%. Additional CCN measurements by a ground-based single column CCNC were performed at Ragged Point, Barbados. During SALTRACE five mineral dust outbreaks were investigated. The CCN measurements in the Caribbean showed three layers with different CCN characteristics during these outbreaks. In the upper part (2.5 to 4.5 km) of the Saharan Air Layer (SAL) in the Caribbean the aerosol properties are similar to the ones measured in the dust layer over Cape Verde and the CCNC measurements show low CCN concentrations and little activated fraction. In contrast, a higher variability was detected in the lower part (0.7 to 2.5 km) of the SAL. Within this layer a much higher CCN activation leads to a larger CCN concentration and cumulus clouds were frequently observed. Below 0.7 km also a high variability in activated fraction was observed, but CCN concentration was lower

    2002-10-01

    The progress and problems in the Caribbean Amblyomma Program (CAP) are reviewed since its inception in 1995. During 1998, there were funding and administrative management problems. USDA resolved the acute funding crisis, and after three years of negotiation, the CAP has now secured an additional euro 1.5 million from the European Community. Changes in administration in 1998 included the withdrawal of IICA from the program, and the transition during the decentralization of administrative and financial management from FAO headquarters to the Regional Office for Latin America and the Caribbean, based in Chile. A general overview of technical progress and one case study, St. Kitts, is presented. One major concern that emerged during 2000 is that the elimination of the small remaining tropical bont tick (TBT) "hot spots" in both St. Kitts and St. Lucia remained elusive. Why is this so? Egrets? Alternative residual hosts? Or is it fatigue in both technical and administrative management functions? Of even greater concern is the finding of two, apparently new, foci in St. Croix (USVI) in the north and St. Vincent in the south. A critical overview of the program has identified one major remaining constraint-an appropriate management support function at both regional and, in some countries, at the national level. A proposal for a revised management strategy, coupled with the identification of a future strategy to succeed the CAP, namely a Caribbean Animal Resources Management (CARM) Program. PMID:12381609

  17. VGG2002, a new high-resolution geoid for Venezuela and Eastern Caribbean

    Science.gov (United States)

    Acuña, G.; Bosch, W.

    2003-04-01

    This paper describes a new high-resolution geoid for Venezuela and the East Caribbean Sea. The Venezuelan Gravimetric Geoid 2002 (VGG2002) covers the area between 0oN-20oN and 285oE-305oE with a resolution of 1'x1'. An additional 2o-zone was included to avoid boundary effects. About 1.5 million free-air gravity anomalies were used. They originate from PDVSA (Petróleos de Venezuela S.A.), BGI (Bureau Gravimetrique International) and the GEODAS data base of NGDC (National Geophysical Data Center). In marine areas, 1'x1' gravity anomalies derived from altimetry (S&Sv9.1) were also included. In order to determined the long wavelength geoid signal the EGM96 global geopotential model was used as reference. Short wavelength contributions were derived from a digital terrain model with 30'' (GTOPO30 model) and 2' (S&Sv8.2 model) resolution respectively. Using the GRAVSOFT software, the geoid undulations were computed with the remove-restore technique. The computation involves a spherical approximation to evaluate the Stokes integral by two dimensional spherical Fast Fourier Transform with 100% zero-padding. The terrain corrections were computed by Residual Terrain Model method using prism numeric integration and taking into account the topographic anomalies relative to a mean height surface of 15'x15' resolution. This surface was obtained by a moving average of the digital terrain model. In marine areas the height anomalies were completed by mean sea level deviations of POCM, an oceanographic model of the ocean dynamic topography. Subsequently, the quasi-geoid was converted to geoid heights. The accuracy was evaluated by about 300 GPS/leveling stations and absolute differences to TOPEX/Poseidon (nine years) mean sea surface profiles. These show that the absolute agreement with respect to the national vertical datum is generally better than 30 cm RMS for most parts of Venezuela, 15 cm RMS in coastal areas and 5 cm RMS at sea.

  18. Rivers in the sea - Can we quantify pigments in the Amazon and the Orinoco River plumes from space?

    Muller-Karger, Frank E.; Walsh, John J.; Carder, Kendall L.; Zika, Rod G.

    1989-01-01

    Coastal Zone Color Scanner (CZCS) images of the western tropical Atlantic (1979-1982) were combined into monthly mean surface pigment fields. These suggest that Amazon River water flows along northeastern South America directly toward the Caribbean sea early in the year. After June, however, the North Brazil Current is shunted eastward, carrying a large fraction of Amazon water into the North Equatorial Countercurrent (NECC). This eastward flow causes diminished flow through the Caribbean, which permits northwestward dispersal of Orinoco River water due to local Ekman forcing. The Orinoco plume crosses the Caribbean, leading to seasonal variation in surface salinity near Puerto Rico. At least 50 percent of the pigment concentration estimated in these plumes seems due to viable phytoplankton.

  19. Sea level trends in South East Asian Seas (SEAS

    Directory of Open Access Journals (Sweden)

    M. W. Strassburg

    2014-10-01

    Full Text Available Southeast Asian Seas (SEAS span the largest archipelago in the global ocean and provide a complex oceanic pathway connecting the Pacific and Indian Oceans. The SEAS regional sea level trends are some of the highest observed in the modern satellite altimeter record that now spans almost two decades. Initial comparisons of global sea level reconstructions find that 17 year sea level trends over the past 60 years exhibit good agreement in areas and at times of strong signal to noise associated decadal variability forced by low frequency variations in Pacific trade winds. The SEAS region exhibits sea level trends that vary dramatically over the studied time period. This historical variation suggests that the strong regional sea level trends observed during the modern satellite altimeter record will abate as trade winds fluctuate on decadal and longer time scales. Furthermore, after removing the contribution of the Pacific Decadal Oscillation (PDO to sea level trends in the past twenty years, the rate of sea level rise is greatly reduced in the SEAS region. As a result of the influence of the PDO, the SEAS regional sea level trends during 2010s and 2020s are likely to be less than the global mean sea level (GMSL trend if the observed oscillations in wind forcing and sea level persist. Nevertheless, long-term sea level trends in the SEAS will continue to be affected by GMSL rise occurring now and in the future.

    During 2013, Arctic sea ice extent remained well below normal, but the September 2013 minimum extent was substantially higher than the record-breaking minimum in 2012. Nonetheless, the minimum was still much lower than normal and the long-term trend Arctic September extent is -13.7 per decade relative to the 1981-2010 average. The less extreme conditions this year compared to 2012 were due to cooler temperatures and wind patterns that favored retention of ice through the summer. Sea ice thickness and volume remained near record-low levels, though indications are of slightly thicker ice compared to the record low of 2012.

  17. Mangroves Enhance Reef Fish Abundance at the Caribbean Regional Scale.

    Directory of Open Access Journals (Sweden)

    Joseph E Serafy

    Full Text Available Several studies conducted at the scale of islands, or small sections of continental coastlines, have suggested that mangrove habitats serve to enhance fish abundances on coral reefs, mainly by providing nursery grounds for several ontogenetically-migrating species. However, evidence of such enhancement at a regional scale has not been reported, and recently, some researchers have questioned the mangrove-reef subsidy effect. In the present study, using two different regression approaches, we pursued two questions related to mangrove-reef connectivity at the Caribbean regional scale: (1 Are reef fish abundances limited by mangrove forest area?; and (2 Are mean reef fish abundances proportional to mangrove forest area after taking human population density and latitude into account? Specifically, we tested for Caribbean-wide mangrove forest area effects on the abundances of 12 reef fishes that have been previously characterized as "mangrove-dependent". Analyzed were data from an ongoing, long-term (20-year citizen-scientist fish monitoring program; coastal human population censuses; and several wetland forest information sources. Quantile regression results supported the notion that mangrove forest area limits the abundance of eight of the 12 fishes examined. Linear mixed-effects regression results, which considered potential human (fishing and habitat degradation and latitudinal influences, suggested that average reef fish densities of at least six of the 12 focal fishes were directly proportional to mangrove forest area. Recent work questioning the mangrove-reef fish subsidy effect likely reflects a failure to: (1 focus analyses on species that use mangroves as nurseries, (2 consider more than the mean fish abundance response to mangrove forest extent; and/or (3 quantitatively account for potentially confounding human impacts, such as fishing pressure and habitat degradation. Our study is the first to demonstrate at a large regional scale (i

    2016-02-01

    Full Text Available Women and men are traditionally cast in different roles, with males being leaders in the workplace, home and government. In contrast, communities promote women as caregivers who support male leaders and shape future generations as mothers, mentors and teachers. In recognition of this societal view of women that often led to inequality and inequity, the UNDP listed Gender Equality and empowering women as one of eight Millennium Development Goals. The post-2015 Sustainable Development Goals, adopted by the United Nations in autumn 2015, also included gender equality and empowering women as Goal 5. In its work in the Caribbean, the Caribbean Local Economic Development Project (CARILED examined gender as it relates to micro, small and medium enterprise (MSME development in six Caribbean countries.  The findings of this study showed gender gaps for both male and female entrepreneurs in different areas of development.  Traditionally gendered roles for MSME sectors, access to financing and lack of adequate guidance or community support were some areas that affected men and women differently in the region.  The study outlines ways in which male and female leaders can address traditional gender roles by identifying priority areas for development, creating an enabling environment for start-ups and expansion, and fostering a policy and legislative base that facilitates ease of doing business.  The recommendations further describe the public–private partnerships needed to successfully meet gender gaps, and the importance of both elected officials and technocrats in inter alia community engagement and advocacy towards local economic development. The importance of gender equality among elected officials and technocrats, and the influence gender has on determining priority areas of focus within local government strategic plans for communities are also set out within this paper.

    I review some unsolved problems in Caribbean active tectonics. At the regional and plate scale: 1) confirm the existence of intraplate deformation zones of the central Caribbean plate that are within the margin of error of ongoing GPS measurements; 2) carry out field studies to evaluate block models versus models for distributed fault shear on the densely populated islands of Jamaica, Hispaniola, Puerto Rico, and the Virgin Islands; 3) carry out paleoseismological research of key plate boundary faults that may have accumulated large strains but have not been previously studied in detail; 4) determine the age of onset and far-field effects of the Cocos ridge and the Central America forearc sliver; 4) investigate the origin and earthquake-potential of obliquely-sheared rift basins along the northern coast of Venezuela; 5) determine the age of onset and regional active, tectonic effects of the Panama-South America collision including the continued activation of the Maracaibo block; and 6) validate longterm rates on active subduction zones with improving, tomographic maps of subducted slabs. At the individual fault scale: 1) determine the mode of termination of large and active strike -slip faults and application of the STEP model (Septentrional, Polochic, El Pilar, Bocono, Santa Marta-Bucaramanaga); 2) improve the understanding of the earthquake potential on the Enriquillo-Plantain Garden fault zone given "off-fault" events such as the 2010 Haiti earthquake; how widespread is this behavior?; and 3) estimate size of future tsunamis from studies of historic or prehistoric slump scars and mass transport deposits; what potential runups can be predicted from this information?; and 4) devise ways to keep rapidly growing, circum-Caribbean urban populations better informed and safer in the face of inevitable and future, large earthquakes.

    2012-01-01

    During the last twenty years, Hispanic Caribbean cinema has slowly developed roles to represent lesbians. In order to draw a conceptual map and to examine the un/successfulness of this new lesbian "public image," I analyze both independent films that challenge the status quo by portraying openly lesbian characters and mainstream films that insist on denying autonomy to same-sex love. Whereas commercial markets may deem an openly lesbian role transgressive, queer female roles can be considered "appropriate." Gender-queering functions as a symbolically transitional stage toward lesbian visibility and inclusion.

    Whale sharks, Rhincodon typus, are often perceived as solitary behemoths that live and feed in the open ocean. To the contrary, evidence is accumulating that they are gregarious and form seasonal aggregations in some coastal waters. One such aggregation occurs annually north of Cabo Catoche, off Isla Holbox on the Yucatán Peninsula of Mexico. Here we report a second, much denser aggregation of whale sharks (dubbed "the Afuera") that occurs east of the tip of the Yucatán Peninsula in the Carib...

    A 61-cm core was obtained from 4 metres below the water table in Cenote Aktun Ha, on the Yucatan Peninsula, Mexico. The cenote is 8.6 km from the Caribbean coast and its formation and evolution have been largely affected by sea-level change. The base of the core dates to 6940 - 6740 cal yr BP and overlying sediments were deposited rapidly over the subsequent ~200 years. The pollen record shows that the cenote evolved from a marsh dominated by red mangrove (Rhizophora mangle) and fern (Polypodiaceae) to an open-water system. These vegetation changes were controlled by water level and salinity and are thus useful indicators of past sea level. At the base, the d13C isotopic ratios reveal the influence of terrestrial vegetation (-29‰), but shift to more negative values up-core (-33‰), indicating an influence from particulate matter in the flooded cenote pool. Although microfossil populations were nearly absent through most of the core, the microfossil assemblage in the upper 6 cm of the core is dominated by juvenile Ammonia tepida and the thecamoebian genus Centropyxis. These populations indicate open-water conditions in the cenote and a major environmental shift around 6600 cal yr BP, which is related to sea-level rise in the Caribbean basin. These data fit well with previously established sea-level curves for the Caribbean Sea. Our reconstruction of the environmental history of Cenote Aktun Ha helps elucidate the floral and hydrological history of the region, and highlights the utility of cenote sediments for studying the Holocene sea-level history of the Caribbean Sea.

  5. Unraveling The Complex Interaction Between The Southern Caribbean, Northwest South America And The Pacific Plates During The Cenozoic

    We have studied the prominent Sierra Nevada de Santa Marta Massif (the highest peak in the world whose local base is at sea level, ~5.75km) in Northern Colombia and we are interested in quantifying the thermal and tectonic history of the Northernmost Andes during the Cenozoic in order to understand the complex interaction between the Caribbean, the South American and the Pacific plates. In order to do so, apatite fission track data (by the LA-ICP-MS method) has been used, collected along several traverses and a single vertical profile within the massif. Our results show that the easternmost part of Sierra Nevada de Santa Marta exhumed at elevated rates (≥0.2 Km/My) during 65-58 Ma in response to the collision of the Caribbean Plateau with north-western South America. A second pulse of exhumation (≥0.32 Km/My) during 50-40 Ma was probably driven by the underthrusting of the Caribbean Plate beneath northern South America. More southern portions of the Sierra Nevada de Santa Marta (the Sierra Nevada Province) exhumed rapidly during 26-29 Ma (~0.7 Km/My), whereas farther north, the northwestermost corner of the Sierra Nevada de Santa Marta (the Santa Marta Province) exhumed at elevated rates during 30-25 Ma and 25-16 Ma. Our thermochronological data show that the highest exhumation rates within the Sierra Nevada de Santa Marta progressed towards the northwest via the propagation of NW-verging thrusts. The late Oligocene-Miocene exhumation was mainly a consequence of compression originating at the Pacific margin of South America that also gave rise to uplift and exhumation in other regions of Eastern Colombia (e.g. in the Santander Massif). Major continental faults such as the left-lateral Santa Marta-Bucaramanga Fault have played an important role transferring the deformation, Exhumation of the Sierra Nevada de Santa Marta Massif is not recorded after ~16 Ma, which is unexpected, given the high elevation and high erosive power of the climate, implying that rock and

    Full Text Available The region of Latin America and the Caribbean is known for being the most socially unequal in the world and for this has highly segmented societies, which affects the education, integration and social cohesion of the population. Expanding opportunities for everyone to have access to quality education and developing more inclusive schools, which would educate within and for diversity, stand out as two powerful strategies in a move towards more just and democratic societies in Latin America. This paper presents a detailed analysis of the educational situation in the region from the perspective of rights and inclusion, with particular attention paid to those individuals and groups that suffer most from the impact of inequality, exclusion and marginalization. This analysis begins with an assessment the progress and challenges still to be made regarding access, attendance, quality and equity of education in Latin America. In the second part it addresses the major issues on the agenda of Inclusion in Latin America and the Caribbean.

    1997-01-01

    This paper presents the results of a study commissioned by the Latin American and Caribbean Technical Department of the World Bank to document and analyze health expenditures in Latin America and the Caribbean. In 1990, the countries of this region spent US$ 69 billion on health, with an average per capita health expenditure of US$ 162. On average, the countries spent 6.2% of their GDP on health, with the expenditures divided about equally between the public and private sectors. In both the public and private sectors, per capita health expenditures were positively and significantly correlated with per capita income. However, this relationship holds only for the public sector, when health expenditures are measured as a proportion of GDP. While several poorer countries were dependent on external assistance, with increasing income, the countries relied more on public expenditures to finance health care. Based on the limited time series data, it is evident that there was a considerable variation among countries regarding the proportion spent on capital investments, primary health care, and drugs, but not on salaries. Looking ahead, with increasing economic development, the proportion of GDP spent on health, along with public health expenditure as a proportion of total health expenditure, is likely to increase rapidly, while aid dependency is likely to decline.

    1992-09-01

    This article focuses on developing a sustainable tourism in small Caribbean islands, defined here as those that have populations of fewer than 500,000. Such islands share a very fragile ecology and a high dependence on tourism. They differ in their degree of tourist penetration and visitor density and the related degree of environmental degradation. To explain the link between tourism intensity and ecological vulnerability, the so-called “destination life-cycle model” is presented. This suggests that islands pass through three primary stages of tourist development low-density exploration, rapid growth and consolidation, and high-density maturation involving the substitution of man-made for natural attractions. A broad empirical test of the model is performed through a quantitative examination of the tourism characteristics and visitor densities of a cross section of 23 small Caribbean islands. The three basic stages or tourism styles are identified: low-impact emerging areas, high-density mass-market mature destinations, and rapidly growing intermediate islands in between. Some broad strategies consistent with the systems framework for a sustainable tourism with moderate densitites are briefly explored.

  10. Mass coral bleaching in 2010 in the southern Caribbean.

    Full Text Available Ocean temperatures are increasing globally and the Caribbean is no exception. An extreme ocean warming event in 2010 placed Tobago's coral reefs under severe stress resulting in widespread coral bleaching and threatening the livelihoods that rely on them. The bleaching response of four reef building taxa was monitored over a six month period across three major reefs systems in Tobago. By identifying taxa resilient to bleaching we propose to assist local coral reef managers in the decision making process to cope with mass bleaching events. The bleaching signal (length of exposure to high ocean temperatures varied widely between the Atlantic and Caribbean reefs, but regardless of this variation most taxa bleached. Colpophyllia natans, Montastraea faveolata and Siderastrea siderea were considered the most bleaching vulnerable taxa. Interestingly, reefs with the highest coral cover showed the greatest decline reef building taxa, and conversely, reefs with the lowest coral cover showed the most bleaching but lowest change in coral cover with little algal overgrowth post-bleaching.

    Full Text Available Objective: Undertreated pain around the world includes the acute and chronic pain caused by sickle cell disease (SCD. In collaboration with a Caribbean association that aims to provide assistance to those diagnosed with SCD, we surveyed adults with SCD about pain management and impact of SCD pain. Methods: Participants were recruited from a group of 55 adults with SCD. A survey was administered to those who agreed to participate. Questions centred on their self-assessed level of pain due to SCD, the extent to which that pain interferes with daily activities, and how they seek and obtain pain relief. Results: Responses were received from 39 participants (female: n = 28, 72%, male: n = 11, 28%; mean age: 31.6 (SD ± 13.7 years. Sickle cell disease pain significantly disrupts participants’ daily activities (62%, mood (72%, work (64% and sleep (69%. Prescription medicine was ineffective for 41% and about half (n = 19 sought alternate means of relief. Conclusion: Sickle cell disease pain is undertreated in the Caribbean, disrupts daily activities and affects quality of life by impinging on education, employment and marital status. Sickle cell disease and other types of pain can be clinically managed safely, effectively and inexpensively. By failing to palliate and overcome the problem of undertreated pain, healthcare systems and providers contribute to socio-economic amongst other repercussions for sufferers, their families and caregivers, and their nations.

    The kinematic model of the Caribbean plate presented by DeMets et al. (2007) is based on velocities from 6 continuous and 14 campaign GPS sites. COCONet is a multi-hazard GPS-Met observatory, which extends the existing infrastructure of the PBO in North America into the Caribbean basin. In 2010, UNAVCO in collaboration with UCAR, was funded by NSF to design, build, and initially maintain a network of 50 new cGPS/Met sites and include data from another 50 existing sites in the Caribbean region. The COCONet siting plan is for 46 new stations, 21 refurbished stations, and 77 existing stations across 26 nations in the Caribbean region. Data from all COCONet sites flow into the UNAVCO archive and are processed by the PBO analysis centers and are also processed independently by the UTA Geodesy Lab using GIPSY-OASISII (v.6.3) using an APP strategy and final, precise orbits, clocks, and EOP from JPL in the IGS08r frame. We present a refined estimate of Caribbean plate motion by evaluating data from an expanded number of stations with an improved spatial distribution. In order to better constrain the eastern margin of the plate near the Lesser Antilles subduction interface, campaign GPS observations have been collected on the island of Dominica over the last decade. These are combined with additional campaign observations from the western Caribbean, specifically from Honduras and Nicaragua. We have analyzed a total of 117 sites from the Caribbean region, including campaign data and the data from the cGPS stations that comprise COCONet. An updated velocity field for the Caribbean plate is presented and an inversion of the velocities for 24 sites yields a plate angular velocity that differs from previously published models. Our best fitting inversion to GPS velocities from these 24 sites suggests that 2-plate model for the Caribbean is required to fit the GPS observations, which implies that the Caribbean is undergoing modest (1-3 mm/yr) deformation within its interior.

    Orbicella annularis is an abundant ecological cornerstone framework-building Scleractinian coral throughout the Caribbean Sea. The O. annularis holobiont (biotic and abiotic components of the coral) is negatively impacted by increased exposure to anthropogenic pollution. This is consistently evidenced by altered tissue cellular composition, and skeletal structure. The O. annularis' holobiont is weakened by increased exposure to sewage and ship bilge pollution. Pollution exposure is characterized by decreased skeletal growth, as well as decreased zooxanthellae and chromatophore tissue cell densities. Healthy colonies studied at five sites on the leeward coast of Curacao, along a systematically decreasing pollution concentration, were sampled from the back-reef depositional facies of a protected fringing reef tract. A unidirectional oceanographic current flows to the NW past the city of Willemstad, a large point source of human sewage and ship bilge. This setting creates an ideal natural laboratory for in situ experimentation that quantitatively tracks the impact to coral physiology along a gradient from unimpacted to polluted seawater. Our lab has established laser scanning microscopy for three-dimensional (3D) quantification of zooxanthellae, and chromatophore cellular tissue density. X-ray computed tomography (BioCT) was used for analysis of skeletal density. Zooxanthellae density decreased as pollution concentration increased. Chromatophore density showed no significant relationship with pollution concentration but varied dramatically within each site. This suggests zooxanthellae density is highly impacted by environmental stress while variation in chromatophore density is driven by genetic variation. These results will be used to create a new model for environmental impacts on coral physiology and skeletal growth.

  17. Downscaled projections of Caribbean coral bleaching that can inform conservation planning.

    Projections of climate change impacts on coral reefs produced at the coarse resolution (~1°) of Global Climate Models (GCMs) have informed debate but have not helped target local management actions. Here, projections of the onset of annual coral bleaching conditions in the Caribbean under Representative Concentration Pathway (RCP) 8.5 are produced using an ensemble of 33 Coupled Model Intercomparison Project phase-5 models and via dynamical and statistical downscaling. A high-resolution (~11 km) regional ocean model (MOM4.1) is used for the dynamical downscaling. For statistical downscaling, sea surface temperature (SST) means and annual cycles in all the GCMs are replaced with observed data from the ~4-km NOAA Pathfinder SST dataset. Spatial patterns in all three projections are broadly similar; the average year for the onset of annual severe bleaching is 2040-2043 for all projections. However, downscaled projections show many locations where the onset of annual severe bleaching (ASB) varies 10 or more years within a single GCM grid cell. Managers in locations where this applies (e.g., Florida, Turks and Caicos, Puerto Rico, and the Dominican Republic, among others) can identify locations that represent relative albeit temporary refugia. Both downscaled projections are different for the Bahamas compared to the GCM projections. The dynamically downscaled projections suggest an earlier onset of ASB linked to projected changes in regional currents, a feature not resolved in GCMs. This result demonstrates the value of dynamical downscaling for this application and means statistically downscaled projections have to be interpreted with caution. However, aside from west of Andros Island, the projections for the two types of downscaling are mostly aligned; projected onset of ASB is within ±10 years for 72% of the reef locations.

    As charismatic mega-fauna, sea turtles attract many volunteers to conservation programs. This article examines the ways in which volunteers value sea turtles, in the specific context of volunteers working with the Caribbean Conservation Corporation, at Tortuguero, Costa Rica. The complexity of volunteer values is explored using a qualitative approach. In-depth interviews with 31 volunteers were conducted in July of 1999 and 2000. Interviews probed, among other things, interest in sea turtles and their conservation, motives for participating, and the most gratifying parts of their volunteer experience. Results show that volunteers hold multiple and complex values for sea turtles, but particular values dominate. Results have implications for understanding human-environment relations and the emerging study of volunteer tourism. There are also management implications for volunteer programs hoping to attract participants.

    Isla del Coco is the only land mass of the Cocos Plate that emerges above sea level. This makes it the only place where Cocos Plate motion can be measured using Global Navigation Satellite System (GNSS) monitoring. Global Positioning System (GPS) observations have been carried out sporadically over more than two decades on Isla del Coco, allowing precise measurement of the motion of the Cocos Plate. Recently, in May 2011, a continuous GPS station was built and instrumented at Isla del Coco, in Wafer Bay, by OVSICORI UNA and UNAVCO, as part of the COCONet regional GNSS network. Position time series from this CGPS station (ISCO: Isla del Coco) show a steady motion of Isla del Coco at a speed of 90.9±1.5mm/yr in the N35oE direction in ITRF2008 and convergence with the Caribbean Plate at 78±1mm/yr. This result is consistent with the findings of the earliest GPS studies, and agrees within uncertainty with the estimated convergence rate of 76.4±2.6 mm/yr of the MORVEL plate motion model. MORVEL is based on an average over the last 780,000 years, and our result suggests that Cocos Caribbean plate motions have been constant over that time interval.

    This research attempted to test an HIV prevention intervention for Afro-Caribbean female teens. The purpose was to improve knowledge and attitudes concerning HIV/AIDS, improve mother-daughter sexual communication, and to reduce risky sexual behaviors. Using a community-based approach, sixty mother and daughter pairs were randomly assigned. One condition was experimental using the Making Proud Choices Caribbean Style (MPCCS); another was a comparison of General Health Education. Independent t-tests were used for analysis between the pretest, posttest and 90 days posttests. MPCCS indicated clear usage with other Caribbean teens. This study helped to support the theory when Afro-Caribbean (AC) teens feel they need to become sexually active (subjective norm), and have referent support (parental support), they may blend values, knowledge, and skills (control beliefs), and are likely to make proud choices to reduce risky sexual behavior in minimizing HIV in their communities.

    Between July 2000 and August 2001 forty-three air samples were collected in the northern Caribbean: Twenty-six in the US Virgin Islands, and 17 samples aboard ship during two 1-week cruises. Samples were collected during African dust events and non-dust conditions and screened for the presence of culturable bacteria and fungi. A total of 3,652 liters of air were collected during non-dust conditions, with 19 bacteria and 28 fungi being recovered. During dust conditions a total of 2,369 liters of air were screened resulting in the recovery of 171 bacteria and 76 fungi. A statistically significant difference was found between the two data sets. These results support previous African dust research and further demonstrate that dust particles can serve as a vessel for the global dispersion of bacteria and fungi. Dustborne microorganisms may play a significant role in the ecology and health of downwind ecosystems.

    Full Text Available In this period, the key to the relationship between India and Latin America and the Caribbean (LAC was based in the political nature of this liaison: it was a "uni-multilateral" relationship, centered in India, where LAC countries operated as a group of autonomous entities (an "island chain" structure, and not as a unit of a supranational character with unified international conduct (an island structure. As we will see, faced with uniform and consistent Indian policies, LAC had national policies which make it impossible to discuss a regional policy towards India. The goal of this work is to form a general characterization of the bilateral policies during the period of the Cold War with the intent of identifying the key explanatory factors of the process. While this may be a limited objective, it addresses the non-existence of an academic debate surrounding the topic. We intend to contribute an analysis which in this phase is primarily descriptive.

    Full Text Available This article seeks to investigate whether there is a potential for border integration among four adjoining Caribbean countries: Colombia, Nicaragua, Panama and Costa Rica. The discussion is part of the “cross-border” concept and the integration of subnational entities in two or more nation states, with particular emphasis on the role played by the societies that inhabit border regions. A comparative analysis model is used to assess border regulations in each country’s various territorial levels based on relevant legal elements, autonomous processes and decentralization. The article concludes that the more modern each country’s border regulations and constitutional, political and administrative reforms are, the greater the likelihood of cross-border integration. Colombia and Nicaragua have the highest potential for integrating their borders, whereas Panama and Costa Rica have the lowest potential.

    This special section of the Journal of Geophysical Research reports a multi-investigator study of a number of sunlight-initiated photoprocesses taking place in the varied biogeochemical and oceanographic environment found in the tropical Eastern Caribbean and Orinoco River delta in the spring and fall of 1988. Principal conceptual themes that were addressed by the program included (1) the characterization of the role of dissolved organic matter as the main chromophore initiating photoprocesses in surface seawater, (2) the determination of the fluxes and pathways of reactants and transient species involved in oxygen photoredox chemistry, and (3) the continuing development of chemical mapping strategies, including observing and modelling reactive phototransient distribution in terms of their sources, mixing, and fates. Ancillary supporting studies included observation of water mass tracers, dissolved trace gases, atmospheric components, nutrients and the geochemistry of estuarine mixing processes in an important continental margin. The observational and mechanistic investigations reported here feature a number of novel or improved methods allied with some advanced underway sampling, sensing and computing facilities that were implemented aboard the R/V Columbus Iselin. Results from the study showed large-scale ([approximately]1,000 km) seasonal variations in surface water photoreactivity, optical and biooptical characteristics over much of the Caribbean basin. These changes resulted from seasonally varying riverine inputs of organic chromophores, nutrients and suspended material. Smaller scale (10-100 km) studies carried out in the Orinoco delta and the Gulf of Paria showed that estuarine mixing processes did not affect major net removal of dissolved organic matter, consistent with the hypothesis that riverine chromophore input plays a dominant role in open-water photochemistry. 56 refs., 4 figs., 1 tab.

    Coastal mangroves lose large amounts of water through evapotranspiration (ET) that can be equivalent to the amount of annual rainfall in certain years. Satellite remote sensing has been used to estimate surface energy and ET variability in many forested ecosystems, yet has been widely overlooked in mangrove forests. Using a combination of long-term datasets (30-year) acquired from the NASA Landsat 5 and 7 satellite databases, the present study investigated ET and surface energy balance variability between two mangrove forest sites in the Caribbean: 1) Everglades National Park (ENP; Florida, USA) and 2) Sian Ka'an Biosphere Reserve (SKBR; Quintana Roo, Mexico). A satellite-derived surface energy balance model was used to estimate ET in tall and scrub mangroves environments at ENP and SKBR. Results identified significant differences in soil heat flux measurements and ET between the tall and scrub mangrove environments. Scrub mangroves exhibited the highest soil heat flux coincident with the lowest biophysical indices (i.e., Fractional Vegetation Cover, Normalized Difference Vegetation Index, and Soil-Adjusted Vegetation Index) and ET rates. Mangrove damage and mortality was observed on the satellite images following strong tropical storms and associated with anthropogenic modifications and resulted in low values in spectral vegetation indices, higher soil heat flux, and higher ET. Recovery of the spectral characteristics, soil heat flux and ET was within 1-2 years following hurricane disturbance while, degradation caused by human disturbance persisted for many years. Remotely sensed ET of mangrove forests can provide estimates over a few decades and provide us with some understanding of how these environments respond to disturbances to the landscape in periods where no ground data exists or in locations that are difficult to access. Moreover, relationships between energy and water balance components developed for the coastal mangroves of Florida and Mexico could be

This study indicates that biotic processes of root production and benthic mat formation are important controls on accretion and elevation change in mangrove ecosystems common to the Caribbean Region. Quantification of specific biological controls on elevation provides better insight into how sustainability of such systems might be influenced by global (e.g., climate, atmospheric CO 2) and local (e.g., nutrients, disturbance) factors affecting organic matter accumulation, in addition to relative sea-level rise.

  5. The Diasporic Dimensions of British Caribbean Federation in the Early Twentieth Century

    Full Text Available [Second and third pragraph] While much has been written on the significance of British Caribbean activists in various movements associated with black diaspora politics in the twentieth century, particularly their important roles in Pan-African struggles, little has been written on how the various British Caribbean colonies themselves were envisioned among diaspora activists and within the scope of black diaspora politics. Did such Caribbean activists, especially those interested in and connected to diasporic movements beyond the British Caribbean, and their African American and African counterparts forsake the British West Indies as a focus of political engagement for other lands and causes? If not, what was the place of “West Indian liberation” and nation building in the British Caribbean in relation to black diasporic struggles in the early twentieth century? This article address these questions through an examination of how the idea of a united “West Indian nation” (via a federation or closer union among British Caribbean colonies was envisioned within black diaspora politics from the turn of the twentieth century through the 1920s, and the ways in which racial consciousness and motivations informed conceptualizations of such a nation among black political activists of the British Caribbean and other parts of the diaspora. This study argues that efforts to create a federation in the Anglophone Caribbean were much more than simply imperial or regional nation-building projects. Instead, federation was also a diasporic, black nation-building endeavor intricately connected to notions of racial unity, racial uplift, and black self-determination.

    Over 75 tsunamis have been documented in the Caribbean and Adjacent Regions during the past 500 years. Since 1500, at least 4484 people are reported to have perished in these killer waves. Hundreds of thousands are currently threatened along the Caribbean coastlines. In 2005 the Intergovernmental Coordination Group for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (CARIBE EWS) was established. It recommended the following minimum seismic performance standards for the detection and analysis of earthquakes: 1) Earthquake detection within 1 minute, 2) Minimum magnitude threshold = M4.5, and 3) Initial hypocenter error of seismic stations in the Caribbean and Adjacent Regions. The NOAA National Weather Service Caribbean Tsunami Warning Program prepares and distributes monthly reports on real time and archived seismic data availability of the contributing stations at the US Tsunami Warning Centers, the Puerto Rico Seismic Network and IRIS. As of early 2014, 99 of the proposed stations are being contributed by national, regional and international seismological institutions. Recent network additions (Nicaragua, Colombia, Mexico, Cayman Islands, and Venezuela) have reduced detection threshold, time and location error throughout much of the Caribbean region and Central America. Specifically, earthquakes (>M4.0) can be detected within 1 minute throughout much of the Caribbean. The remaining exceptions to this standard for detection are portions of northern South America and Mexico. Another performance criterion is 90% data availability. Currently 60-70% of the stations meet this standard. The presentation will further report on the status of the CARIBE EWS seismic capability for the timely and accurate detection and analysis of earthquakes for tsunami warning purposes for the Caribbean and Adjacent Regions.

    Full Text Available Saba Bank, a submerged atoll in the Caribbean Sea with an area of 2,200 km2, has attained international conservation status due to the rich diversity of species that reside on the bank. In order to assess the role of Saba Bank as a potential reservoir of diversity for the surrounding reefs, we examined the population genetic structure, abundance and health status of two prominent benthic species, the coral Montastraea cavernosa and the sponge Xestospongia muta. Sequence data were collected from 34 colonies of M. cavernosa (nDNA ITS1-5.8S-ITS2; 892 bp and 68 X. muta sponges (mtDNA I3-M11 partition of COI; 544 bp on Saba Bank and around Saba Island, and compared with published data across the wider Caribbean. Our data indicate that there is genetic connectivity between populations on Saba Bank and the nearby Saba Island as well as multiple locations in the wider Caribbean, ranging in distance from 100s-1000s km. The genetic diversity of Saba Bank populations of M. cavernosa (π = 0.055 and X. muta (π = 0.0010 was comparable to those in other regions in the western Atlantic. Densities and health status were determined along 11 transects of 50 m2 along the south-eastern rim of Saba Bank. The densities of M. cavernosa (0.27 ind. m-2, 95% CI: 0.12-0.52 were average, while the densities of X. muta (0.09 ind. m-2, 95% CI: 0.02-0.32 were generally higher with respect to other Caribbean locations. No disease or bleaching was present in any of the specimens of the coral M. cavernosa, however, we did observe partial tissue loss (77.9% of samples as well as overgrowth (48.1%, predominantly by cyanobacteria. In contrast, the majority of observed X. muta (83.5% showed signs of presumed bleaching. The combined results of apparent gene flow among populations on Saba Bank and surrounding reefs, the high abundance and unique genetic diversity, indicate that Saba Bank could function as an important buffer for the region.

    The structurally and stratigraphically complex area of North Panama deformed belt, Sinu-Uraba accretionary prism and south Caribbean deformed belt holds the key to understand the plate tectonic evolution of the southwestern margins of the Caribbean Sea. New geological fieldworks, sedimentary and structural analysis, detailed offshore and onshore seismic interpretation provide insights into the regional structural and stratigraphic evolution of those margins. Detailed results constraint the geodynamic history of these complex wedge architecture which registered successive changes of sedimentary supplies and gravity collapses. During the Paleocene and Eocene time, the southeastward subduction of the Caribbean plate below the northwestern edge of South America is characterized by the development of an accretionary wedge off the Caribbean margin of Colombia, due to the accumulation of a large amount of sediments provided by the Magdalena and the Sinu rivers. The Atrato river, at that time, was providing sediments to the basins restricted within the Panama Isthmus. During the Middle Miocene, the Panama Isthmus began to collide against South America, inducing the uplift of the San Jacinto/Sinu Belt in Colombia. As a consequence, the Magdalena river was deviated northward. The Sinu river was also deviated to the North and started to load the back of the the Sinu accretionary wedge which then began to collapse as convergence has ceased. In the same way, the uplift of the Darien Shear Zone, east of the Atrato basin, has deflected the sedimentary supply from the Chucunaque/Tuira basins to the northern margin of the isthmus, allowing the development of a sedimentary basin and the initiation of the North Panama Deformed Belt. Thus, on one hand, the structure of the Colombian Wedge, the Sinu Wedge and the North Panama Deformed belt, was controlled by the tectonic forces, a consequence of the convergence and progressive accretion of the Central American isthmus against the

    Ferguson, Renae Luenell

    The purpose of this study was to describe the perspectives of Caribbean high school students' experiences in American science classrooms. Research suggests that psychological, cultural, and socioeconomic perspectives influence the science experiences of African Americans or Blacks; the result of which is under-representation (Lewis et al., 2000). Nonetheless, what is uncertain is if these and other perspectives are similar to the science experiences of Caribbeans who also are majority black by race and rank as the 3 rd largest immigrant population in America's schools (Suarez-Orozco, 2000). Questions guiding this study were: (1) What are the perspectives of Caribbean high school students' experiences in American science classrooms? (2) What can we learn from the perspectives of Caribbean high school students' science experiences that may address issues of participation and interest; consequently, influencing the overall performance of ethnic minorities in school science? Sociocultural theory provides the framework for the analysis of the study. Four Caribbean born students in an American high school participated in this naturalistic qualitative research. A constant comparative method was used to categorize and analyze the data and uncover meaningful patterns that emerged from the four interviews and written documents. Although there were similarities between African Americans' science experiences as documented in the literature and that of Caribbeans in this study, the Caribbean participants relied on prior native experiences to dictate their perspectives of their science experiences in America. According to Caribbean students, American science high schools classrooms utilize an objective style of assessments; are characterized by a lack of teacher support; allow behavioral problems in the classroom; and function through different communication styles than the native Caribbean science classroom environment. This study implies science educators should be sensitive

    2013-04-01

    Food security is major focus of Caribbean governments, with production being of particular concern. For the past three decades, Caribbean agriculture has been declining in relative importance, both in terms of its contribution to GDP and its share of the labour force. One of the problems Caribbean agriculture faces is the destructive impacts from weather and climate extremes. These include flood, drought, extreme temperatures, and strong winds from tropical cyclones. Other potential disasters, such as from pests and diseases attacks, are also weather and climate driven. These make weather and climate information critically important to decision-making in agriculture in the Caribbean region. In an effort to help reduce weather and climate related risks to the food security sector, The Caribbean Institute for Meteorology and Hydrology, along with its partners the Caribbean Agricultural Research and Development Institute, the World Meteorological Organization (WMO) and ten National Meteorological Services from within the Caribbean Community launched and implemented the Caribbean Agrometeorological Initiative (CAMI). From 2010 to 2013, CAMI set out to provide relevant information to farmers, and the industry in general, for decision and policy making. The project is funded by the European Union through the Science and Technology Programme of the African, Caribbean and Pacific Group of Countries' (ACP). The overarching objective of CAMI was to increase and sustain agricultural productivity at the farm level in the Caribbean region through improved applications of weather and climate information, using an integrated and coordinated approach. Currently, this is done through (i) provision of relevant climate information appropriately disseminated, (ii) predictions on seasonal rainfall and temperature, (iii) support for improved irrigation management, (iv) the development of strategically selected weather-driven pest and disease models, (v) use of crop simulation models

  14. Cellular responses in sea fan corals: granular amoebocytes react to pathogen and climate stressors.

    Directory of Open Access Journals (Sweden)

    Laura D Mydlarz

    Full Text Available BACKGROUND: Climate warming is causing environmental change making both marine and terrestrial organisms, and even humans, more susceptible to emerging diseases. Coral reefs are among the most impacted ecosystems by climate stress, and immunity of corals, the most ancient of metazoans, is poorly known. Although coral mortality due to infectious diseases and temperature-related stress is on the rise, the immune effector mechanisms that contribute to the resistance of corals to such events remain elusive. In the Caribbean sea fan corals (Anthozoa, Alcyonacea: Gorgoniidae, the cell-based immune defenses are granular acidophilic amoebocytes, which are known to be involved in wound repair and histocompatibility. METHODOLOGY/PRINCIPAL FINDINGS: We demonstrate for the first time in corals that these cells are involved in the organismal response to pathogenic and temperature stress. In sea fans with both naturally occurring infections and experimental inoculations with the fungal pathogen Aspergillus sydowii, an inflammatory response, characterized by a massive increase of amoebocytes, was evident near infections. Melanosomes were detected in amoebocytes adjacent to protective melanin bands in infected sea fans; neither was present in uninfected fans. In naturally infected sea fans a concurrent increase in prophenoloxidase activity was detected in infected tissues with dense amoebocytes. Sea fans sampled in the field during the 2005 Caribbean Bleaching Event (a once-in-hundred-year climate event responded to heat stress with a systemic increase in amoebocytes and amoebocyte densities were also increased by elevated temperature stress in lab experiments. CONCLUSIONS/SIGNIFICANCE: The observed amoebocyte responses indicate that sea fan corals use cellular defenses to combat fungal infection and temperature stress. The ability to mount an inflammatory response may be a contributing factor that allowed the survival of even infected sea fan corals during a

    Full Text Available What are the determinant factors of community assemblies in the most diverse ecosystem in the ocean? Coral reefs can be divided in continental (i.e., reefs that develop on the continental shelf, including siliciclastic reefs and oceanic (i.e., far off the continental shelf, usually on volcanic substratum; whether or not these habitat differences impose community-wide ecological divergence or species exclusion/coexistence with evolutionary consequences, is unknown.Studying Caribbean octocorals as model system, we determined the phylogenetic community structure in a coral reef community, making emphasis on species coexistence evidenced on trait evolution and environmental feedbacks. Forty-nine species represented in five families constituted the species pool from which a phylogenetic tree was reconstructed using mtDNA. We included data from 11 localities in the Western Caribbean (Colombia including most reef types. To test diversity-environment and phenotype-environment relationships, phylogenetic community structure and trait evolution we carried out comparative analyses implementing ecological and evolutionary approaches.Phylogenetic inferences suggest clustering of oceanic reefs (e.g., atolls contrasting with phylogenetic overdispersion of continental reefs (e.g., reefs banks. Additionally, atolls and barrier reefs had the highest species diversity (Shannon index whereas phylogenetic diversity was higher in reef banks. The discriminant component analysis supported this differentiation between oceanic and continental reefs, where continental octocoral species tend to have greater calyx apertures, thicker branches, prominent calyces and azooxanthellate species. This analysis also indicated a clear separation between the slope and the remaining habitats, caused by the presence or absence of Symbiodinium. K statistic analysis showed that this trait is conserved as well as the branch shape.There was strong octocoral community structure with opposite

    During a cruise with RV Meteor in the spring of 2010, magnetic measurements were carried out in the central and western Caribbean with up to six magnetic sensors deployed at the same time. These were i) a towed gradiometer consisting of two Overhauser sensors, ii) two towed vector magnetometers, and iii) two shipboard oriented vector magnetometers. While the gradiometer data provide total field magnetic anomalies free from external variations, the vector data can be analyzed with different methods in the space and wavenumber domains. In the case of the towed vector data, attitude control is challenging whereas shipboard data require a very thorough compensation for the ship's magnetic field. The data were analyzed with the goal to gain insight into the origin of the basement rocks especially of the western Caribbean. Position and strike direction of magnetic anomalies in the Columbia basin possibly hold the key to distinguish between an origin of the crust in the Pacific ocean and an alternative in situ formation between the Americas. On six long profiles in the Columbia basin and adjacent regions we find consistently strike directions of the magnetic anomalies around N100°E which seems to be incompatible with a Pacific origin of the crust. Three Project Magnet aeromagnetic vector profiles crossing the research area at different angles were analyzed with the same method and yield very similar results. In our interpretation, the crust underlying the Columbia basin formed during the Cretaceous at a roughly E-W trending spreading center between the Americas. Since the crust likely formed during the Cretaceous Superchron (C 34), the strike direction we find in our data probably does not represent typical seafloor spreading anomalies. Instead we believe it is related to changes in the intensity of the Earth's magnetic field which are known to have left correlated traces in oceanic crust formed during this period. The analysis methods we used are sensitive to intensity

  17. Perspectives on communication problems in the English-speaking Caribbean.

    The Caribbean is experiencing a host of serious socioeconomic problems that prevent the majority of the population from realizing and maintaining a satisfactory standard of living. Food and Nutrition Surveys of some countries identified a lack of information on health, food, and nutrition as a primary reason for the prevalence of malnutrition, infectious diseases, and nutrition related diseases. "Misinformation" creates an often insurmountable barrier to effective communication between source and receiver, in this case the health, food, and nutrition sector and the wider community. Misinformation occurs when the message is either incorrect, incomplete, inconsistent with other messages in the same program, or contradictory. This element of "misinformation" can negate the effectiveness of the message and an entire communication program. Some examples are cited which show that in programs aimed at effecting change in attitude or behavior it is essential to ensure that messages are clearly communicated to avoid misunderstanding and the right infrastructure is in place for the innovation proposed by the message to be carried out. In the Jamaica Nutrition Education Program (JNEP) were used to communicate the messages. Evaluation revealed that health staff were providing incorrect and contradictory advice about breastfeeding, which showed that they lacked basic information on the subject. In Barbados, despite an intensified health education campaign, face to face instruction in the clinics, and extensive use of the Caribbean Food and Nutrition Institute (CFNI) Breastfeeding Package as well as other locally developed materials, a marked decline in breastfeeding was recorded over the 1969-81 survey period. Misinformation and misunderstanding among mothers were identified as the key reasons for the failure of breastfeeding. In relation to the decline in breaastfeeding and incorrect weaning practices, mass media was implicated as luring mothers away from natural feeding

  18. Sawfishes and Other Elasmobranch Assemblages from the Mio-Pliocene of the South Caribbean (Urumaco Sequence, Northwestern Venezuela)

    2015-01-01

    The Urumaco stratigraphic sequence, western Venezuela, preserves a variety of paleoenvironments that include terrestrial, riverine, lacustrine and marine facies. A wide range of fossil vertebrates associated with these facies supports the hypothesis of an estuary in that geographic area connected with a hydrographic system that flowed from western Amazonia up to the Proto-Caribbean Sea during the Miocene. Here the elasmobranch assemblages of the middle Miocene to middle Pliocene section of the Urumaco sequence (Socorro, Urumaco and Codore formations) are described. Based on new findings, we document at least 21 taxa of the Lamniformes, Carcharhiniformes, Myliobatiformes and Rajiformes, and describe a new carcharhiniform species (†Carcharhinus caquetius sp. nov.). Moreover, the Urumaco Formation has a high number of well-preserved fossil Pristis rostra, for which we provide a detailed taxonomic revision, and referral in the context of the global Miocene record of Pristis as well as extant species. Using the habitat preference of the living representatives, we hypothesize that the fossil chondrichthyan assemblages from the Urumaco sequence are evidence for marine shallow waters and estuarine habitats.

    The CARICOMP monitoring network gathered standardized data from 52 seagrass sampling stations at 22 sites (mostly Thalassia testudinum-dominated beds in reef systems) across the Wider Caribbean twice a year over the period 1993 to 2007 (and in some cases up to 2012). Wide variations in community total biomass (285 to >2000 g dry m(-2)) and annual foliar productivity of the dominant seagrass T. testudinum (2000 g dry m(-2)) were found among sites. Solar-cycle related intra-annual variations in T. testudinum leaf productivity were detected at latitudes > 16°N. Hurricanes had little to no long-term effects on these well-developed seagrass communities, except for 1 station, where the vegetation was lost by burial below ∼1 m sand. At two sites (5 stations), the seagrass beds collapsed due to excessive grazing by turtles or sea-urchins (the latter in combination with human impact and storms). The low-cost methods of this regional-scale monitoring program were sufficient to detect long-term shifts in the communities, and fifteen (43%) out of 35 long-term monitoring stations (at 17 sites) showed trends in seagrass communities consistent with expected changes under environmental deterioration.

    The deep ocean is the largest and least-explored ecosystem on Earth, and a uniquely energy-poor environment. The distribution, drivers and origins of deep-sea biodiversity remain unknown at global scales. Here we analyse a database of more than 165,000 distribution records of Ophiuroidea (brittle stars), a dominant component of sea-floor fauna, and find patterns of biodiversity unlike known terrestrial or coastal marine realms. Both patterns and environmental predictors of deep-sea (2,000–6,500 m) species richness fundamentally differ from those found in coastal (0–20 m), continental shelf (20–200 m), and upper-slope (200–2,000 m) waters. Continental shelf to upper-slope richness consistently peaks in tropical Indo-west Pacific and Caribbean (0–30°) latitudes, and is well explained by variations in water temperature. In contrast, deep-sea species show maximum richness at higher latitudes (30–50°), concentrated in areas of high carbon export flux and regions close to continental margins. We reconcile this structuring of oceanic biodiversity using a species–energy framework, with kinetic energy predicting shallow-water richness, while chemical energy (export productivity) and proximity to slope habitats drive deep-sea diversity. Our findings provide a global baseline for conservation efforts across the sea floor, and demonstrate that deep-sea ecosystems show a biodiversity pattern consistent with ecological theory, despite being different from other planetary-scale habitats.

  5. Extreme-wave deposits in the Caribbean - towards an improved tsunami hazard assessment

    Science.gov (United States)

    2016-04-01

    Coastal zones worldwide experience considerable population pressure and demand for a management of hazards such as tsunamis. Tsunami hazard assessment is the initial step of the management process and requires reliable information on frequency and magnitude. In areas with short historical documentation, these long-term frequency-magnitude patterns, which are best explained by inverse power-law functions, mainly rely on geological traces. According to the historical record covering the last 520 years, Caribbean tsunami hazard is demonstrated by more than 80 mostly regional or local seismically induced events. However, based on two numerical hydrodynamic models of tsunamis spawning at the Muertos Trough and the South Caribbean Deformed Belt (SCBD), two trigger scenarios only marginally considered so far, we show that pan-Caribbean tsunamis can be taken into account as well. We furthermore review more than 50 studies for possible geological evidence of tsunamis in the Caribbean including fine-grained subsurface deposits and subaerial coarse clasts, and re-evaluate their implications for tsunami hazard assessment against state-of-the-art models of tsunami deposition. Only a limited number of reliable palaeotsunami records with consistent and robust age control were identified, hampering inter-island or interregional correlation of deposits. Separating between storm and tsunami transport of solitary boulders is very difficult in most cases. Those arranged in ridges or incorporated into polymodal ridge complexes or ramparts, respectively, which line many windward coasts of the Caribbean, can mainly be attributed to long-term formation during strong storms implying the overprinting of potential tsunami signatures. The quantification of parameters of tsunami flooding based on tsunami deposits, such as flow depth, inundation distance or flow velocity, by applying inverse and forward numerical models of sediment transport is still underdeveloped in the Caribbean and needs to

  6. Nursing empire: travel letters from Africa and the Caribbean.

    2013-02-01

    This essay analyses colonial nurses' travel letters, written from West Africa and the Caribbean between the turn of the century and 1920, in order to better understand the role of nurses in forming satellite versions of home. Though their primary function was to 'nurse empire' by helping to repair and maintain the bodies needed for imperial labour, nurses also contributed to written discourses supporting Britain's economic interests and political goals. Through careful consideration of primary archival material, this essay analyses the rhetorical modes that may have helped nurses gain professional and personal authority abroad. It considers nurses as moving within several kinds of imperial networks - geographical, institutional and discursive - and traces the shifts in their written self-representation according to these different contexts. In order to reform nursing, in the mid-nineteenth century Florence Nightingale defined the 'New Nurse's' ideal personality as well as her duties. Ever since, the nurse's 'character' has often been essentialised in literature and culture. As Julia Hallam observes in Nursing the Image (2000), the nurse is commonly portrayed as ministering angel, potential seductress, battleaxe or doctor's helpmate. The goal of this essay is to resist simplifying nurses' cultural significance, motivations or experiences by studying the multiple influences to which colonial nurses were subject and the shifting registers in their writing.

    The phenomenon known as red tide has been a topic of great interest in that there is concern that the scale and complexity of this natural phenomenon are expanding. It is known that the benthic dinoflagellate, Gambierdiscus toxicus, produces a variety of polyether toxins that contaminate seafood and result in human illness. Maitotoxin (MTX) is one of the toxins that have been implicated in ciguatera seafood poisoning. There is a need for the development of a much broader understanding of the nature of the poisoning toxins. MTX cogeners can be difficult to isolate due to its size and chemical nature. A major goal is to obtain a purified standard of a Caribbean MTX so that more efficient assays can be developed to test seafood for the presence of toxins and thus avoid human harm. The primary goal of this project is to obtain large amounts of pure maitotoxin. The procedure described is also useful as a starting point for the purification of other toxins.

    African dust carried to the Tropical Atlantic and Caribbean was measured during the summer months of 2015. Atmospheric particles during dust events were collected at Cape San Juan, Puerto Rico on stacked-filter units and a high-volume sampler for the fine and coarse fractions and on a low-pressure impactor for size-resolved characterization. The filter ash gravimetric method was used to determine bulk dust mass concentrations for the first time in Puerto Rico. The method was validated analyzing same filter portions at CIAM/ACAR University of Puerto Rico and at RSMAS/MAC University of Miami. Filter's extracts were analyzed for ionic species measured by ion chromatography. The water-soluble organic carbon (WSOC) was determined with a total organic carbon (TOC) analyzer. Mineral dust concentrations in Puerto Rico were compared to those reported at Miami during summer periods. Comparison between dust concentration and regional PM10 data and results on size-resolved dust concentration will also be presented.

    The Great American Biotic Interchange has been the predominant paradigm for explaining biotic diversification in the Nearctic/Neotropical overlap or Mexican Transition Zone, which is commonly explained by the collision of the North and South American continental plates, which began in the Oligocene and fused both landmasses. In the most far-reaching cladistic biogeographical analysis of the area to date, evidence has been found supporting the existence of a remnant Caribbean region extending from eastern Mexico to southeastern USA, a hypothesis that challenges current views of the Great American Biotic Interchange and the Mexican Transition Zone. We show herein that an older terrane, which has drifted to the present day positions of Yucatan and Cuba, may be biogeographically linked to an early ‘Gondwanan’ biota of the Paleocene (ca. 60 Ma). The evidence indicates an east west biotic divide in Mexico, existing before the collision and formation of Central America. The south north division of the country, previously recognized by several authors as associated with the Great American Biotic Interchange and the Mexican Transition Zone, is of a younger age.

  10. Corruption and Political Participation in the Americas and the Caribbean

    2015-08-01

    Full Text Available This article deals with an issue as yet little explored in the vast literature about political participation: the role of corruption in political engagement. It investigates whether the coexistence, the values and the perception of citizens in relation to corrupt practices and actors have effects on political activism, and it verifies the direction in which this is evolving, whether it is in the direction of engagement in or withdrawal from politics. The unit of analysis is the individual, the geographic sector includes the Americas and the Caribbean, and the time frame includes biennial intervals between 2004 and 2012. A theoretical discussion and empirical analysis of the data from the Americas Barometer is used. Five distinct types of political participation were identified: contact with political and governmental actors, community activism, partisan and electoral activism, voter turnout and protest activism. The article concludes that the experience with corruption and the tolerance for bribe increase the chances of engagement in participative activities, going against the principal contributions of the specialized literature.

    2014-12-01

    The post-settlement phase of broadcast-spawned coral life histories is poorly known due to its almost complete undetectability and, hence, presumed low abundance in the field. We used lab-cultured settled polyps of two important Caribbean reef-building species with negligible larval recruitment to quantify early post-settlement survivorship (6-9 weeks) over multiple years/cohorts and differing orientation on a reef in the Florida Keys. Orbicella faveolata showed significantly and consistently better survivorship in vertical rather than horizontal orientation, but no discernable growth overall. Meanwhile, Acropora palmata showed no significant difference in survivorship between orientations, but significantly greater growth in the horizontal orientation. Both species showed significant variation in mean survivorship between cohorts of different years; 0-47 % for O. faveolata and 12-49 % for A. palmata over the observed duration. These results demonstrate wide variation in success of cohorts and important differences in the larval recruitment capacities of these two important but imperiled reef-building species.

  12. Herpetofauna of Neguanje, Tayrona National Natural Park, Colombian Caribbean

    International Nuclear Information System (INIS)

    The Herpetofauna of the Tayrona National Natural Park (Neguanje sector) was studied during 30 days between September and October 2004 by visual records, an active search and the arrangement of barriers with pitfall traps interception. 44 species (11 of amphibians and 33 of reptiles), distributed in 18 families and 37 genera, were registered. The species accumulation curves showed that approximately 20 days are sufficient to record all species of lizards, but not for the species of frogs and snakes. The lizard Lepidoblepharis sanctaemartae was the most abundant species recorded on the sector, which implies a potential advantage to assure its protection. The local distribution of the Colostethus ruthveni species, which had been reported in 1997 elsewhere for the Sierra Nevada de Santa Marta, was extended. Finally, this study reveals that the herpetofauna at Neguanje represents 33% of the total number of species reported for the Sierra Nevada de Santa Marta, which has positioned this area as one of the most representative in terms of biodiversity in the Colombian Caribbean.

    The literature dealing with health and entrepreneurship has focused on developed countries. We use a sample of almost 5000 business owners and wage-workers from four Caribbean Basin countries to study this relationship. Analyses are performed using data from the Global Entrepreneurship Monitor along with the Visual Analogue Scale of the EQ-5D-5L instrument as an overall health rating. The results show that business owners are healthier than wage-workers, which is in line with the findings from studies in developed countries. Furthermore, better health is associated with a lower likelihood for fear of business failure to be a deterrent to new business formation, a greater likelihood of self-belief in having the skills to run a business, and an increased recognition of start-up business opportunities among wage-workers. These positive associations between health and entrepreneurial perceptions provide new evidence about why less healthy individuals refrain from entrepreneurship. Finally, we find that the healthiest business owners run the companies with the highest growth expectations.

    Full Text Available An economical supply of hygienic potable water is one of the most pressing public health issues facing developing countries in the Caribbean region today. This project investigates the performance of a novel solar photochemical reactor for disinfecting river water. The prototype photochemical reactor was designed, constructed, and tested for the microbiological degradation of faecal coliform present in River Water. The experiments evaluated the efficacy of two photosensitive dyes (malachite green and methylene blue as agents for detoxification with concentrations ranging from 0.5 to 3.0 mg/L. The photochemical reactor operated in a single-pass mode and compared the disinfection rates with direct photolysis. The photosensitizers showed a high efficacy rate using natural sunlight with microbial reduction ranging from 97 to 99% for concentrations as low as 0.5 mg/L of dye. The sensitizers were found to be photobleaching and were very effective at lower concentrations (0.01. Post-solar disinfection included the use of a coconut fiber filter which polished the water removing residual dye concentrations and bacterial contaminants.

    Transpressive deformation at the northern Caribbean plate boundary is accommodated mostly by two major strike-slip faults, but the amount and location of accommodation of the compressional component of deformation are still debated. We collected marine geophysical data including multibeam bathymetry and multichannel seismic reflection profiles along this plate boundary around Hispaniola, in the Jamaica Passage, and in the Gulf of Gonâve. The data set allows us to image the offshore active strike-slip faults as well as the compressional structures. We confirm that the Enriquillo-Plantain-Garden Fault Zone (EPGFZ) in the Jamaica Passage has a primary strike-slip motion, as indicated by active left-lateral strike-slip-related structures, i.e., restraining bend, asymmetrical basin, en echelon pressures ridges, and horsetail splay. Based on topographic cross sections across the EPGFZ, we image a very limited compressional component, if any, for at least the western part of the Jamaica Passage. Toward the east of the Jamaica Passage, the fault trace becomes more complex, and we identify adjacent compressional structures. In the Gulf of Gonâve, distributed folding and thrust faulting of the most recent sediments indicate active pervasive compressional tectonics. Estimates of shortening in the Jamaica Passage and in the Gulf of Gonâve indicate an increase of the compressional component of deformation toward the east, which nonetheless remains very small compared to that inferred from block modeling based on GPS measurements.

  18. Genetic Diversity in the Lesser Antilles and Its Implications for the Settlement of the Caribbean Basin.

    Directory of Open Access Journals (Sweden)

    Jada Benn Torres

    Full Text Available Historical discourses about the Caribbean often chronicle West African and European influence to the general neglect of indigenous people's contributions to the contemporary region. Consequently, demographic histories of Caribbean people prior to and after European contact are not well understood. Although archeological evidence suggests that the Lesser Antilles were populated in a series of northward and eastern migratory waves, many questions remain regarding the relationship of the Caribbean migrants to other indigenous people of South and Central America and changes to the demography of indigenous communities post-European contact. To explore these issues, we analyzed mitochondrial DNA and Y-chromosome diversity in 12 unrelated individuals from the First Peoples Community in Arima, Trinidad, and 43 unrelated Garifuna individuals residing in St. Vincent. In this community-sanctioned research, we detected maternal indigenous ancestry in 42% of the participants, with the remainder having haplotypes indicative of African and South Asian maternal ancestry. Analysis of Y-chromosome variation revealed paternal indigenous American ancestry indicated by the presence of haplogroup Q-M3 in 28% of the male participants from both communities, with the remainder possessing either African or European haplogroups. This finding is the first report of indigenous American paternal ancestry among indigenous populations in this region of the Caribbean. Overall, this study illustrates the role of the region's first peoples in shaping the genetic diversity seen in contemporary Caribbean populations.

    Barbados is the easternmost island in the Caribbean region, and is uniquely situated between the Atlantic Ocean and Caribbean Sea. Being an isolated island with a karstified aquifer providing the majority of the nation's water resources, Barbados has found itself in water scarce situations in recent years. Groundwater recharge is determined mainly by precipitation variability, and thus a better understanding of long-term shifts in rainfall patterns in the region will aid in future water resource management. To date, speleothem proxy records provide robust, absolutely-dated records of past climatic changes, such as precipitation, yet continued improvement in analytical methods is needed to fully exploit their usefulness as paleoclimate records. This study presents a paleoclimate reconstruction for the Late Holocene on Barbados using stable and radiogenic isotope ratios in speleothem lamina as proxies. In addition, it introduces the use of novel mineralogical analyses using Raman spectroscopy and large chamber-scanning electron microscopy to supplement the oxygen isotope record. For the past 1,500 years, the speleothem record indicates average δ18O values near -4.1 0/00, maximum δ18O values around -3.2 ‰ that coincide with the Little Ice Age climate event, while minimum δ18O values around -5.3 ‰ occur during the Medieval Climate Anomaly. Raman spectral analysis shows a recent period of increased Mg substitution, which may result from changes in groundwater recharge and potentially represents anthropogenic changes to the island's epikarst aquifer caused by European settlement and sugar cane cultivation on Barbados. Electron imaging revealed chemically distinct layers of detritus within the stalagmite sample, facilitating precise sampling for U-series dating while also providing some information on the nature of bedrock weathering. Additionally, time series analysis of the isotope record indicates multidecadal and multicentennial periodicities that conform well

    We compiled paleostress analyses from previous research works collected at 591 localities of striated fault planes in rocks ranging in age from Late Cretaceous to Quaternary in the circum-Caribbean and Mexico. The purpose of the study is to quantify a progressive clockwise rotation of the Caribbean plate during its Late Cretaceous to recent subduction of the Proto-Caribbean seaway. Paleostress analysis is based on the assumption that slickenside lineations indicate both the direction and sense of maximum resolved shear stress on that fault plane. We have plotted directions of maximum horizontal stress onto plate tectonic reconstructions of the circum-Caribbean plate boundaries and infer that these directions are proxies for paleo-plate motion directions of the Caribbean plate. Plotting these stress directions onto reconstructions provided a better visualization of the relation of stress directions to blocks at their time of Late Cretaceous to recent deformation. Older, more deformed rocks of Late Cretaceous to Eocene ages yield a greater scatter in derived paleostress directions as these rocks have steeper dips, more pervasive faulting, and were likely affected by large rotations as known from previous paleomagnetic studies of Caribbean plate margins. Despite more scatter in measurements from older rock units, four major events that affected the Caribbean plate and the Great Arc of the Caribbean (GAC) are recognizable from changing orientations of stress directions: 1) Late Cretaceous collision of the GAC with southern Mexico and Colombia is consistent with NE directions of maximum compression in rocks of this age range in southern Mexico and EW directions in Colombia as the GAC approached the Proto-Caribbean seaway; 2) Paleocene-Eocene collision of the GAC with the Bahamas platform in Cuba and Hispaniola and with the South American plate in Venezuela is consistent with CW rotations of stress directions in rocks of these ages in the northern Caribbean and CCW

    Seagrasses comprise 78 species and are rarely invasive. But the seagrass Halophila stipulacea, firstly recorded in the Caribbean in the year 2002, has spread quickly throughout the region. Previous works have described this species as invasive in the Caribbean, forming dense mats that exclude native seagrass species. During a reconnaissance field survey of Caribbean seagrass meadows at the islands of Bonaire and Sint Maarten in 2013, we observed that this species was only extremely dense at 5 out of 10 studied meadows. Compared to areas with sparse growth of H. stipulacea, these dense meadows showed consistently higher nutrient concentrations, as indicated by higher leaf tissue N contents of the seagrass Thalassia testudinum (dense when C:N 11.3). Thus, the potential invasiveness of this non-native seagrass most likely depends on the environmental conditions, especially the nutrient concentrations.

    Full Text Available Crime and violence are development issues in the Caribbean. The proliferation of crimes and violence in the Caribbean nations has been a growing concern. This paper presents the worldwide emerging discipline of Forensic Accounting as a veritable Panacea to the challenges posed by crimes and violence. Using the secondary data methodology, it argues that Forensic Accounting which is the intersection between accounting, investigations, and legal matters, will provide the lasting solution which is being earnestly sought to tackle the menace of crimes and violence in the Caribbean. The paper therefore, amongst others, recommends a national and international implementation of Forensic Accounting based measures as a unified approach necessary to fight the Caribbean’s related crime and violence problems.

    2014-01-01

    In 2013, the first autochthonous cases of the chikungunya virus (CHIKV) were reported on the Caribbean island of Saint Martin. The chikungunya virus has since become endemic in the Caribbean due to autochthonous transmission. In the presence of fever and joint symptoms in any traveller returning from the Caribbean, CHIKV should be considered. Although symptoms resemble those of dengue fever, the course of chikungunya is milder. Chikungunya much more commonly causes chronic joint pain. Laboratory tests for the chikungunya virus may give false positive results due to cross reactions with closely related viruses, so taking a full disease and travel history from the patient is necessary in order to interpret these test results correctly. There is no specific treatment for the chikungunya virus. A correct diagnosis can prevent unnecessary additional tests and unjustified treatment. The chikungunya virus can be prevented by the use of insect-repelling substances, nets and air-conditioning. PMID:25269640

  6. Investigations at regional scales of reconstruct sea level variability over the past 50 years

    Sea level rise is a major consequence of global warming, which threatens many low-lying, highly populated coastal regions of the world. In such regions, sea level rise amplifies other stresses due to natural phenomena (e.g., sediment load-induced ground subsidence in deltaic areas, vertical ground motions due to tectonics, volcanism and post-glacial rebound, etc.) or human activities (e.g., ground subsidence due to ground water pumping and/or oil extraction, urbanisation, etc.). Observations for the recent decades from tide gauges and satellite altimetry show that sea level rise is far from being geographically uniform. Here we present an analysis of decadal / multi-decadal sea level variations in a number of selected regions: Tropical Pacific, Indian Ocean, Gulf of Mexico and Caribbean region. For that purpose, we use a reconstruction of past sea level -last 50 years- based on the joint statistical analysis of tide gauge records and gridded sea level from an ocean circulation model. We highlight the sea level trends over the past 50 years in each region. Comparison between reconstructed sea-level trends with tide gauge records at sites not included in the reconstruction shows general good agreement, suggesting that regional trend patterns infer from the reconstruction are realistic (in addition, reconstructed sea-level agrees well with altimeter measurements since 1993). We find above-global average sea level rise since 1950 at several islands in the Eastern Tropical Pacific (Funafuti, Samoa, Kiribati, Cook Islands). Empirical Orthogonal Function (EOF) analyses are performed for each region to describe accurately the spatio-temporal interannual variability. We also compute spatial trend patterns in thermal expansion to determine which part of the observed regional sea level variability can be attributed to change in ocean temperature.

    The cultural context in the United States is racialized and influences Black Caribbean immigrants' acculturation processes, but what role it plays in Black Caribbean immigrants' acculturation into specific facets of American society (e.g., African American culture) has been understudied in the field of psychology. The present study extends research on Black Caribbean immigrants' acculturative process by assessing how this group's experience of the racial context (racial public regard, ethnic public regard, and cultural race-related stress) influences its engagement in African American culture (i.e., adoption of values and behavioral involvement). Data were collected from 93 Black participants of Caribbean descent, ranging in age from 13 to 45 and analyzed using a stepwise hierarchical regression. The findings highlighted that when Black Caribbean-descended participants perceived that the public held a favorable view of their racial group they were more likely to engage in African American culture. In contrast, when participants perceived that the public held a favorable view of their ethnic group (e.g., Haitian) they were less likely to engage in African American culture. Furthermore, among participants experiencing low levels of cultural race-related stress, the associations between racial public regard and engagement with African American culture were amplified. However, for participants experiencing high cultural race-related stress, their engagement in African American culture did not change as a function of racial public regard. These findings may suggest that, for Black Caribbean immigrants, the experience of the racial context influences strategies that serve to preserve or bolster their overall social status and psychological well-being in the United States.

    Full Text Available Investigates descriptions of Afro-Caribbean dances in early chronicles and historical material. Author focuses on choreography, as well as on musical instruments and their use. He pays special attention to descriptions of the Martinican kalenda dance. He discusses descriptions from the 18th c. of black Caribbean dance in French and other colonies, by priests and others, of the kalenda as a couple dance within a ring, and descriptions of other widespread early dances in the Caribbean, such as chica. Author notes that in these early descriptions the authors focus obsessively on eroticism, thus simplifying and exaggerating the dances as sexual, and ignoring their variety. Further, he analyses early chronicles on other widespread dances in the circum-Caribbean, such as stick-fighting dances, bamboula, djouba, and belair, comparing with present-day Caribbean dances, and on "challenge dancing" involving a dance soloist "challenged" by a lead drummer, found, for instance, in kalenda and rumba. In addition, the author focuses on the dances' musical accompaniment by drums, and the drum types and methods, specifically transverse drumming and drumming with sticks on the side of the drum, found today in kalenda, and other Caribbean styles. He points at the inaccuracy of some chronicles, mixing up dance names, and recurring superficiality and stereotypes. He nonetheless concludes from them that slaves from the Congo/Angola region probably played a crucial role in forming these early dance styles, and that their spread was connected with French colonialism and slavery and migrations from (once French colonies. He describes probable Congolese/Angolan influences, such as pelvic isolation, challenge dances, couple dancing within a circle, and transverse drumming, but indicates that these are over time combined with other African and other influences.

    Full Text Available Abstract Background The strategies that parents use to guide and discipline their children may influence their emotional health. Relatively little research has been conducted examining the association of parenting practices to depressive symptoms among Caribbean adolescents. This project examines the association of parenting styles to levels of depressive symptoms among adolescents in Jamaica, the Bahamas, St. Kitts and Nevis, and St. Vincent. Methods Adolescents attending grade ten of academic year 2006/2007 in Jamaica, the Bahamas, St. Vincent, and St. Kitts and Nevis were administered the Parenting Practices Scale along with the BDI-II. Authoritative, Authoritarian, Permissive and Neglectful parenting styles were created using a median split procedure of the monitoring and nurturance subscales of the Parenting Practices Scale. Multiple regression analyses were used to examine the relationships of parenting styles to depressive symptoms. Results A wide cross-section of tenth grade students in each nation was sampled (n = 1955; 278 from Jamaica, 217 from the Bahamas, 737 St. Kitts and Nevis, 716 from St. Vincent; 52.1% females, 45.6% males and 2.3% no gender reported; age 12 to 19 years, mean = 15.3 yrs, sd = .95 yrs. Nearly half (52.1% of all adolescents reported mild to severe symptoms of depression with 29.1% reporting moderate to severe symptoms of depression.

    Full Text Available BACKGROUND: Past research suggests that perceived neighbourhood conditions may influence adolescents' emotional health. Relatively little research has been conducted examining the association of perceived neighbourhood conditions with depressive symptoms among Caribbean adolescents. This project examines the association of perceived neighbourhood conditions with levels of depressive symptoms among adolescents in Jamaica, the Bahamas, St. Kitts and Nevis, and St. Vincent. METHODS: Adolescents attending grade ten of the academic year 2006/2007 in Jamaica, the Bahamas, St. Vincent, and St. Kitts and Nevis were administered the Neighbourhood Characteristics Questionnaire along with the BDI-II. Social cohesion, attachment to the neighbourhood, neighbourhood quality, neighbourhood crime, and neighbourhood disorder scales were created by summing the relevant subscales of the Neighbourhood Characteristics Questionnaire. Multiple regression analyses were used to examine the relationships of perceived neighbourhood conditions to depressive symptoms. RESULTS: A wide cross-section of tenth grade students in each nation was sampled (n = 1955; 278 from Jamaica, 217 from the Bahamas, 737 St. Kitts and Nevis, 716 from St. Vincent; 52.1% females, 45.6% males and 2.3% no gender reported; 12 to 19 years, mean = 15.3 yrs, sd = .95 yr. Nearly half (52.1% of all adolescents reported mild to severe symptoms of depression with 29.1% reporting moderate to severe symptoms of depression. Overall, Jamaican adolescents perceived their neighbourhoods in a more positive manner than those in the Bahamas, St. Vincent and St. Kitts and Nevis. Results of a series of hierarchical multiple regression analyses suggested that a different pattern of neighbourhood factors for each island were associated with depressive symptoms. However, neighbourhood factors were more highly associated with depressive symptoms for Jamaican students than for students in the other three

    Full Text Available The archaeology of Amerindian settlements in the Caribbean has mostly been identified through scatters of artefacts; predominantly conglomerations of shells, ceramics and lithics. While archaeological material may not always be visible on the surface, particular settlement patterns may be identifiable by a topography created through cultural action: earthen mounds interchanging with mostly circular flattened areas. In northern Hispaniola, recent foot surveys have identified more than 200 pre-colonial sites of which several have been mapped in high resolution. In addition, three settlements with topographical characteristics have been extensively excavated, confirming that the mounds and flattened areas may have had a cultural connotation in this region. Without the availability of high resolution LiDAR (Light Detection and Ranging data, a photogrammetric approach using UAS (unmanned aircraft system, commonly known as drones can fill the knowledge gap on a local scale, providing fast and reliable data collection and precise results. After photogrammetric processing, digital clearance of vegetation, and extraction of the georeferenced DEM (digital elevation model and orthophoto, filters and enhancements provide an opportunity to visualize the results in GIS. The outcome provides an overview of site size, and distribution of mounds and flattened areas. Measurement of the topographic changes in a variety of past settlements defines likely zones of habitat, and provides clues on the actual dimensions and density of living space. Understanding the relation of the mounds and adjacent flat areas within their environment allows a discussion on how, and for what purpose, the settlement was founded at a particular location, and provides clues about its spatial organization.

  13. Recruitment and resilience of a harvested Caribbean octocoral.

    Directory of Open Access Journals (Sweden)

    Howard R Lasker

    Full Text Available Disturbance events are an important component of the ecology of coral reefs and increasingly frequent disturbances coupled with a lack of population resilience may contribute to changes in the structure of coral reef communities. The harvest of the Caribbean octocoral Antillogorgia elisabethae provides an opportunity to explore the relationship between adult abundance and recruitment and the manner in which recruitment contributes to the resilience of local populations. Recruitment of A. elisabethae was monitored in 20, 1-m(2 quadrats at 8 sites along the southern edge of the Little Bahama Bank from 2004 through 2007. A. elisabethae has been harvested in The Bahamas for over fifteen years and all of the sites had been harvested three times, including a harvest during the course of the study. Abundances of adult colonies at those sites as well as a location that had not been harvested were also determined. Recruitment was highly variable, differing between sites, transects within sites, and, depending on the site, between years. Recruitment was best correlated with adult abundance averaged across the surrounding site. Regression analyses suggest abundance on smaller scales had only small effects on recruitment. The effects of the harvesting were site specific ranging from a 38 to 67% reduction in the density of mature colonies. The sites with the most abundant A. elisabethae continued to have the highest abundances after harvesting and there was no significant difference in recruitment before and after harvesting. Population size-structure at 6 of 8 sites that have been harvested multiple times exhibited an overall depletion in small colonies suggesting long term suppression of recruitment and declining populations. Severe depression of adult abundances coupled with local recruitment can create a negative feedback and lead to the decline of local populations. Populations that are dependent on self-recruitment are not resilient to large

  14. Non-stationary background intensity and Caribbean seismic events

    We consider seismic risk calculation based on models with non-stationary background intensity. The aim is to improve predictive strategies in the framework of seismic risk assessment from models describing at best the seismic activity in the Caribbean arc. Appropriate statistical methods are required for analyzing the volumes of data collected. The focus is on calculating earthquakes occurrences probability and analyzing spatiotemporal evolution of these probabilities. The main modeling tool is the point process theory in order to take into account past history prior to a given date. Thus, the seismic event conditional intensity is expressed by means of the background intensity and the self exciting component. This intensity can be interpreted as the expected event rate per time and / or surface unit. The most popular intensity model in seismology is the ETAS (Epidemic Type Aftershock Sequence) model introduced and then generalized by Ogata [2, 3]. We extended this model and performed a comparison of different probability density functions for the triggered event times [4]. We illustrate our model by considering the CDSA (Centre de Données Sismiques des Antilles) catalog [1] which contains more than 7000 seismic events occurred in the Lesser Antilles arc. Statistical tools for testing the background intensity stationarity and for dynamical segmentation are presented. [1] Bengoubou-Valérius M., Bazin S., Bertil D., Beauducel F. and Bosson A. (2008).

    Sponges are common sessile benthic suspension feeders that play a critical role in carbon and nitrogen cycling within reef ecosystems via their filtration capabilities. Due to the contribution of sponges in benthic-pelagic coupling, it is critical to assess factors that may affect their role in the healthy function of coral reefs. Several factors can influence the rate at which an individual sponge pumps water, including body size, environmental conditions, mechanical blockage, and reduction of inhalant pores (ostia). Symbiotic zoanthid colonization is a common occurrence on Caribbean sponges, and the presence of zoanthids on the surface of a sponge may occlude or displace the inhalant ostia. We quantified pumping rates of the giant barrel sponge, Xestospongia muta ( N = 22 uncolonized, 37 colonized) and the common vase sponge, Niphates digitalis ( N = 21 uncolonized, 17 colonized), with and without zoanthid symbionts, Parazoanthus catenularis and Parazoanthus parasiticus, respectively. For X. muta, biovolume-normalized pumping rates of individuals colonized by zoanthids were approximately 75 % lower than those of uncolonized sponges. Moreover, colonization with zoanthids was related to a difference in morphology relative to uncolonized individuals: Colonized sponges exhibited an osculum area to biovolume ratio that was nearly 65 % less than uncolonized sponges. In contrast, the presence of zoanthids on N. digitalis resulted in only a marginal decrease in pumping rates and no detectable difference in morphology. The difference in zoanthid effects between X. muta and N. digitalis is likely due to the differences in wall thickness and architecture between the two species. The probable cause of reduced pumping in affected sponges is occupation of the sponge surface that leads to blockage or displacement of inhalant ostia. To partially test this hypothesis, zoanthid colonization on specimens of X. muta was simulated by wrapping sponges with plastic mesh of varying

    Glantz, Michael H

    2007-06-01

    The thesis of this article is quite different from many other theses of papers, books, and articles on the Aral Sea. It is meant to purposely highlight the reality of the situation in Central Asia: the Aral Sea that was once a thriving body of water is no more. That sea is dead. What does exist in its place are the Aral seas: there are in essence three bodies of water, one of which is being purposefully restored and its level is rising (the Little Aral), and two others which are still marginally connected, although they continue to decline in level (the Big Aral West and the Big Aral East). In 1960 the level of the sea was about 53 m above sea level. By 2006 the level had dropped by 23 m to 30 m above sea level. This was not a scenario generated by a computer model. It was a process of environmental degradation played out in real life in a matter of a few decades, primarily as a result of human activities. Despite wishes and words to the contrary, it will take a heroic global effort to save what remains of the Big Aral. It would also take a significant degree of sacrifice by people and governments in the region to restore the Big Aral to an acceptable level, given that the annual rate of flow reaching the Amudarya River delta is less than a 10th of what it was several decades ago. Conferring World Heritage status to the Aral Sea(s) could spark restoration efforts for the Big Aral. PMID:17626470

  3. Can sea urchins beat the heat? Sea urchins, thermal tolerance and climate change

    Directory of Open Access Journals (Sweden)

    Elizabeth Sherman

    2015-06-01

    Full Text Available The massive die-off of the long-spined sea urchin, Diadema antillarum, a significant reef grazer, in the mid 1980s was followed by phase shifts from coral dominated to macroalgae dominated reefs in the Caribbean. While Diadema populations have recovered in some reefs with concomitant increases in coral cover, the additional threat of increasing temperatures due to global climate change has not been investigated in adult sea urchins. In this study, I measured acute thermal tolerance of D. antillarum and that of a sympatric sea urchin not associated with coral cover, Echinometra lucunter, over winter, spring, and summer, thus exposing them to substantial natural thermal variation. Animals were taken from the wild and placed in laboratory tanks in room temperature water (∼22 °C that was then heated at 0.16–0.3 °C min−1 and the righting behavior of individual sea urchins was recorded. I measured both the temperature at which the animal could no longer right itself (TLoR and the righting time at temperatures below the TLoR. In all seasons, D. antillarum exhibited a higher mean TLoR than E. lucunter. The mean TLoR of each species increased with increasing environmental temperature revealing that both species acclimatize to seasonal changes in temperatures. The righting times of D. antillarum were much shorter than those of E. lucunter. The longer relative spine length of Diadema compared to that of Echinometra may contribute to their shorter righting times, but does not explain their higher TLoR. The thermal safety margin (the difference between the mean collection temperature and the mean TLoR was between 3.07–3.66 °C for Echinometra and 3.79–5.67 °C for Diadema. While these thermal safety margins exceed present day temperatures, they are modest compared to those of temperate marine invertebrates. If sea temperatures increase more rapidly than can be accommodated by the sea urchins (either by genetic adaptation, phenotypic plasticity

    2016-04-01

    This study assesses the skill of four statistical models in hindcasting North Atlantic annual tropical cyclone (TC) frequency over 1950-2008 with the aim of projecting future activity. Three of the models are motivated by operational statistical forecast schemes and are premised on standard hurricane predictors including sea surface temperatures (SSTs) and near-surface zonal winds. The fourth model uses an SST gradient index previously proposed for Caribbean seasonal rainfall prediction. The statistical models, created from backward regression, explain 24-48% of the observed variability in 1950-2008 annual TC frequency. The future state of the predictors is extracted from the ECHAM5, HadCM3, MRI CGCM2.3.2a, and MIROC3.2 global climate model (GCM) simulations under the Coupled Model Intercomparison Project Phase 3. Models utilizing SST and near-surface wind predictors suggest significant increases in mean annual frequency by 2-8 TCs by 2070-2090, compared to a single surface wind predictor model, indicating that positive trends in SSTs under global warming have a larger relative influence on projections than changes in the variability of the surface winds. Wind-only models exhibit declines in TC frequency, while the SST gradient model yields little change relative to the present-day mean. Backward regression reapplied against the 1990-2008 period, analogous to future warmer oceanic and atmospheric state relative to the earlier years in the record, retains only the Caribbean low-level jet (CLLJ)-type predictors, explaining up to 82% of TC frequency variability and suggesting a more dominant role for the CLLJ in a warmer climate. Projections using the new models show either a more conservative increase or a stronger decrease in frequency, consistent with a stronger CLLJ.
