中文摘要
翻译
该项目涉及地中海的一个实地项目，该项目将采集沉积岩心，用于古气候研究。这项研究将利用有孔虫贝壳的地球化学成分(特别是镉和钡)来确定过去20,000年来地中海的循环。这些信息将被用来检验关于冰川/间冰期环流模式的两个相互竞争的假设中的哪一个可能是正确的。该项目的结果也可能有助于理解控制沉积物有机含量的机制。
英文摘要
This project involves a field program in the Mediterranean Sea to take sedimentary cores that will be used for a paleoclimatic study. That study will use the geochemical composition (Cadmium and Barium especially) of foraminifera shells to determine the circulation of the Mediterranean during the last 20,000 years. That information will be used to examine which of two competing hypotheses on the glacial/interglacial circulation patterns may be correct. The results of this project may also contribute to an understanding of the mechanisms which control the organic content of sediments.
