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. -

The Caribbean Epidemiological Network: the Complexities of Developing a Regional Perspective
The Caribbean epidemiological network: the complexities of developing a regional perspective K.-G. DOUGLAS Project Director, Drug Abuse Project, Caribbean Epidemiology Centre, Trinidad and Tobago J. HILLEBRAND Epidemiology Adviser, United Nations Office on Drugs and Crime, Vienna ABSTRACT The present article describes the geographical, political and cultural difficulties involved in developing a regional drug abuse epidemiological network in the Caribbean. Earlier initiatives such as the Caribbean Community Epidemiology Task Force failed owing to a lack of resources. It was not until 1996 that a major success was achieved, when the Plan of Action for Drug Control Coordination and Cooperation in the Caribbean laid the groundwork for the establishment of a comprehensive and sus- tainable effort to control substance abuse in the region through drug demand reduc- tion. In 1997, the Santo Domingo Declaration against Drugs reinforced the recom- mendation of the Barbados Plan of Action and called for the timely implementation of an epidemiological system for substance abuse. Subsequently, member States of the Caribbean Community allocated resources to the Drug Abuse Epidemiological and Surveillance System Project, which is being implemented by the Caribbean Epidemiology Centre. Within the framework of the project, the Caribbean Drug Information Network was launched in 2001; this concentrates on institution-building, training and the development of practical expertise in survey research. In order for the Network to continue its work, it will need further political support, adequate funding and the ability to link its activities to other aspects of demand reduction. Keywords: Caribbean; drug abuse; demand reduction; epidemiology network; regional initiative. Introduction Features of the sector The Caribbean region has a total land area of 700,000 sq km and comprises a number of islands, including those in the Caribbean Sea, along with the Guianas (Guyana, French Guiana and Suriname). -

During the early history of the Caribbean, islands were sometimes called by the name of the principal settlement as with San Juan for Puerto Rico, Road Town for Tortola, Bassin (an early name for Christiansted) for Saint Croix, or St. John 's for Antigua. This last may have precipitated Saint John in the U.S. Virgin Islands sometimes being mistaken for Antigua or vice versa. A.I.

C.N. Dubelaar Petroglyphs in the U.S. Virgin Islands: A
C.N. DUBELAAR PETROGLYPHS IN THE U.S. VIRGIN ISLANDS: A SURVEY HISTORY OF PETROGLYPH INVESTIGATION IN THE U.S. VIRGIN ISLANDS Petroglyphs in the U.S. Virgin Islands have been reported from St. John, Congo Cay, and St. Croix. They have been mentioned and described in various publications. The first investigator to mention them in the literature was the Dane H. West (see, however, De Booy, below), in the late 18th century. West reported the Reef Bay (there called 'Rif Bay') engravings in St. John, and, in conformity with the general practice in the Caribbean at the time, ascribed them to the Caribs (West 1793:327). Half a century afterwards, this same petroglyph site is again reported by John P. Knox, Pastor of the Dutch Reformed Church in St. Thomas (Knox 1852:17). He called the bay 'Kip Bay'. The first person to supply a description of the Reef Bay (now spelled Rifbay) site, with a drawing showing the greater part of the inscriptions, was H.S. Lund, the Danish physician in St. John, who wrote a report to the Société Royale des Antiquaires du Nord, Copenhagen. The inhabitants of the island told him that the Caribs were the makers of the engravings (Lund 1850-1860). Alphonse Pinart, A French traveller studying aboriginal American cultures, visited several of the Greater and Lesser Antilles, and reported their petroglyphs (Pinart 1890). On p. 8 he mentions the Reef Bay engravings of St. John, which in his opinion are similar to those of Puerto Rico. His figs 2 and 4 on Planche 5 present most of the drawings; he has two more than Lund, whose report is referred to by Pinart. -
FLORA of ST. JOHN, U.S. VIRGIN ISLANDS By
1 Extracted from: FLORA OF ST. JOHN, U.S. VIRGIN ISLANDS by PEDRO ACEVEDORODRÍGUEZ AND COLLABORATORS (MEMOIRS OF THE NEW YORK BOTANICAL GARDEN: 78: 1581. 1996.) INTRODUCTION The island of St. John, formerly known as St. Jan, (Map 1), belongs to the Virgin Island group, a natural appendage of the Puerto Rican bank. The islands making up the Virgin Islands group (St. Thomas, St. John, Tortola, Virgin Gorda, Anegada, and St. Croix) and Puerto Rico (Vieques, Culebra and Puerto Rico) form a geographical, geological, and biological province with many shared natural features. St. John, like most of the other Virgin Islands has a mountainous topography with very small inter mountain valleys and coastal plains. The island has an approximate area of 31 square kilometers, with an eastwest axis of 11 kilometers, and a maximum northsouth axis of approximately 5 kilometers. The highest point on the island is Bordeaux Mountain which reaches 387 m in elevation. The island has no permanent rivers and possesses only a few intermittent streams, which either flow toward the north or south coasts. For the most part, the soil is volcanic in origin and welldrained, with depths to bedrock ranging from 25 to 50 cm. Columbus discovered and named the Virgin Islands on his second trip to the New World in 1493. On November 14th, Columbus and his crew anchored on an island which he named Santa Cruz (St. Croix later by the French). They found the island to be inhabited by Carib Indians, but they did not record how densely populated the island was.
