Surface Currents Near the Greater and Lesser Antilles
SURFACE CURRENTS NEAR THE GREATER AND LESSER ANTILLES by C.P. DUNCAN rl, S.G. SCHLADOW1'1 and W.G. WILLIAMS SUMMARY The surface flow around the Greater and Lesser Antilles is shown to differ considerably from the widely accepted current system composed of the Caribbean Current and Antilles Current. The most prominent features deduced from dynamic topography are a flow from the north into the Caribbean near Puerto Rico and a permanent eastward-flowing counter-current in the Caribbean itself between Puerto Rico and Venezuela. Noticeably absent is the Antilles Current. A satellite-tracked buoy substantiates the slow southward flow into the Caribbean and the absence of the Antilles Current. INTRODUCTION Pilot Charts for the North Atlantic and the Caribbean Sea (Defense Mapping Agency, 1968) show westerly surface currents to the North and South of Puerto Rico. The Caribbean Current is presented as an uninterrupted flow which passes through the Caribbean Sea, Yucatan Straits, Gulf of Mexico, and Florida Straits to become the Gulf Stream. It is joined off the east coast of Florida by the Antilles Current which is shown as flowing westwards along the north coast of Puerto Rico and then north-westerly along the northern edge of the Bahamas (BOISVERT, 1967). These surface currents are depicted as extensions of the North Equatorial Current and the Guyana Current, and as forming part of the subtropical gyre. As might be expected in the absence of a western boundary, the flow is slow-moving, shallow and broad. This interpretation of the surface currents is also presented by WUST (1964) who employs the same set of ship’s drift observations as are used in the Pilot Charts. -

2. Geophysics and the Structure of the Lesser Antilles Forearc1
2. GEOPHYSICS AND THE STRUCTURE OF THE LESSER ANTILLES FOREARC1 G. K. Westbrook, Department of Geological Sciences, University of Durham and A. Mascle and B. Biju-Duval, Institut Français du Pétrole2 ABSTRACT The Barbados Ridge complex lies east of the Lesser Antilles volcanic arc along the eastern margin of the Caribbean Plate. The complex dates in part from the Eocene, and elements of the arc system have been dated as Late Cretaceous and Late Jurassic, although most of the volcanic rocks date from the Tertiary, particularly the latter part. It is probable that the arc system was moved a considerable distance eastward with respect to North and South America during the Tertiary. The accretionary complex can be divided into zones running parallel to the arc, starting with a zone of initial accre- tion at the front of the complex where sediment is stripped from the ocean floor and the rate of deformation is greatest. This zone passes into one of stabilization where the deformation rate is generally lower, although there are localized zones of more active tectonics where the generally mildly deformed overlying blanket of sediment is significant dis- turbed. Supracomplex sedimentary basins that are locally very thick are developed in the southern part of the complex. The Barbados Ridge Uplift containing the island of Barbados lies at the western edge of the complex; between it and the volcanic arc lies a large forearc basin comprising the Tobago Trough and Lesser Antilles Trough. There are major longitudinal variations in the complex that are broadly related to the northward decrease in sedi- ment thickness away from terrigenous sources in South America and that are locally controlled by ridges in the oceanic igneous crust passing beneath the complex. -

Active Structures in the Barbados Accretionary Wedge of the Lesser Antilles Subduction: Implications for Slip Partitioning

Main active structures in the Barbados accretionary wedge of the Lesser Antilles Subduction: implications for slip partitioning Gaëlle Bénâtre1, Nathalie Feuillet1, Hélène Carton1, Eric Jacques1, and Thibaud Pichot2 1Université de Paris, Institut de Physique du Globe de Paris, CNRS UMR7154, Paris, F-75005, France ([email protected]) 2Beicip-Franlab, Rueil-Malmaison, France At the Lesser Antilles Subduction Zone (LASZ), the American plates subduct under the Caribbean plate at a slow rate of ~2 cm/yr. No major subduction megathrust earthquakes have occurred in the area since the 1839 and 1843 historical events, and the LASZ is typically considered weakly coupled. At the front of the LASZ, the Barbados accretionary wedge (BAW) is one of the largest accretionary wedges in the world. The width of the BAW decreases northward, owing to the increasing distance to the sediment source (Orinoco river) and the presence of several aseismic oceanic ridges, in particular the Tiburon ridge, that stops sediment progression. Marine geophysical studies conducted to date over the northern part of the BAW (Guadeloupe-Martinique sector) have mostly focused on resolving the geometry of the backstop. However, the structure of the wedge and the mechanical behavior of the subduction interface remain poorly known. Our study aims to describe the geometry of the BAW by a detailed morpho-tectonic analysis in order to place constraints on present and past dynamic interactions between the subducting and overriding plates. -
Colonisation of the Antilles by South American Fauna: Giant Sunken Islands As a Passageway?
NATIONAL PRESS RELEASE – PARIS – 18 MAY 2021 Colonisation of the Antilles by South American fauna: giant sunken islands as a passageway? Fossils of land animals from South America have been found in the Antilles. The appearance/disappearance of archipelagos is due to tectonic plate movements and glacial- interglacial cycles. Archipelagos have emerged and sunk in a cyclic manner for millions of years, favouring the displacement of the Antilles. Fossils of land animals from South America have been found in the Antilles, but how did these animals get there? According to scientists from the CNRS, l’Université des Antilles, l’Université de Montpellier and d’Université Côte d’Azur, land emerged in this region and then disappeared beneath the waves for millions of years, explaining how some species were able to migrate to the Antilles. This study will be published in June 2021 issue in Earth-Science Reviews. Fossils of land animals from the Antilles, including mammals and amphibians, have their closest relatives in South America. The crossing of the Caribbean Sea from South America was therefore possible, but how? As swimming across the continent must be ruled out, given that several hundred kilometres separate the South American continent from the Antilles, the dispersal of this fauna has been attributed either to natural rafts coming out of the continent's flooded rivers, or to the existence of land bridges that are now submerged. A scientific project involving geologists, palaeontologists and geophysicists1 is now solving some of the mysteries related to these terrestrial species in the Antilles. The researchers have reconstructed the geography of the northern Lesser Antilles over the last 40 million years and have shown that the movements of the tectonic plates at the junction between the Lesser Antilles, the Greater Antilles and the Aves Ridge (an underwater mountain), have several times given birth to archipelagos and islands quite close to each other, which were then swallowed up in the course of time. -

The Application of GIS to the Reconstruction of the Slave-Plantation Economy of St
The Application of GIS to the Reconstruction of the Slave-Plantation Economy of St. Croix, Danish West Indies Daniel Hopkins, Philip Morgan, and Justin Roberts he project of developing a historical-geographical understanding of slavery and the economic and social systems that supported it requires the exploration of primary data sources that have otherwise notT received significant attention. This paper focuses on a remarkable se- ries of maps, cadastral records, and censuses of the island of St. Croix, in the Danish West Indies (now the United States Virgin Islands) which provide uniquely rich materials for the analysis of the workings of an eighteenth-century slave-plantation society. These Danish records are so susceptible to demographic, economic, and cultural analysis, and the information they convey can be so precisely placed within the mapped physical realities of the landscapes of St. Croix, that they may represent a be nchmark for studies of the geography of New World plantation society in general. Atlantic slavery dominated huge agricultural areas, and its profits permeated the European, African, and American economies, to say noth- ing of its cultural implications,1 and research on this tremendously impor- tant subject has proliferated enormously. Most of this work has been published by historians,2 but the dividing line between history—and es- pecially economic history—and geography can of course not be very sharply drawn in the case of the slave-plantation system. Some very solid historical geography of plantation slavery in the Caribbean has been writ- ten, but the field remains quite open.3 The source material is widely scat- tered and by no means uniform or easy to handle, and a great deal of the fundamental record of the geography of slavery doubtless remains to be re- constructed and interpreted. -
