This Science in Developing Countries Program award will support a group of U.S. researchers headed by Professor Robert Ginsburg of the University of Miami to collaborate with a group of Bahamian scientists headed by Dr. R. V. Cant, Chief Hydrologist of the Bahamian government. The purpose of the proposed research is to provide a detailed case study of the meteoric diagenesis of a Holocene sediment deposit. This sand body occurs as a large pocket-beach strandline deposit that abuts against Pleistocene limestones at Great Exuma Island, Bahamas. The research will document all relevant aspects of the hydrogeology, hydrogeochemistry and petrography of the sand body. The proposed study will contribute to our understanding of the relationship between early meteoric carbonate diagenesis and the physical and chemical hydrology of ocean islands. The hydrogeologic aspects of the study will be applied to define the quantity and quality of a potentially important water resource of immediate interest to the Bahamian government. By bringing together a team of geologists with interests in sedimentology, geochemistry and hydrogeology, and allowing them to collaborate with Bahamian water-resources scientists who best know the occurrence of fresh ground water and the hydrogeologic framework of the islands,this award fulfills the objectives of the Science in Developing Countries Program.

发展中国家的科学计划奖将支持以迈阿密大学罗伯特·金斯伯格教授为首的一组美国研究人员与以巴哈马政府首席水文学家R·V·坎特博士为首的巴哈马科学家小组合作。拟议研究的目的是提供一个全新世沉积矿床的大气成岩作用的详细案例研究。这种砂体以大型袖珍海滩岸线沉积的形式出现，紧靠巴哈马大埃克斯马岛的更新世石灰岩。这项研究将记录砂体的水文地质、水文地球化学和岩石学的所有相关方面。拟议的研究将有助于我们理解早期大气碳酸盐成岩作用与海洋岛屿的物理和化学水文学之间的关系。这项研究的水文地质学方面将用于确定巴哈马政府直接感兴趣的潜在重要水资源的数量和质量。通过将对沉积学、地球化学和水文地质学感兴趣的地质学家团队聚集在一起，并允许他们与最了解淡水赋存和岛屿水文地质框架的巴哈马水资源科学家合作，该奖项实现了发展中国家科学计划的目标。
