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.

该项目涉及地中海的一个实地方案， 取一些沉积岩芯， study. 这项研究将使用地球化学成分（镉 特别是钡）的有孔虫壳，以确定 在过去的20,000年里，地中海的环流。 这些信息将被用来研究两个竞争对手中 关于冰期/间冰期环流模式的假设可能 要正确。 该项目的成果也可能有助于 了解控制有机体的机制， 沉积物的含量。
