A Combined Geochemical and Physical Oceanographic Study of Deep Water Formation in the Red Sea

9416712施拉格在这个项目中，PIS将使用地球化学和物理技术研究红海的深水形成。地球化学工作将包括获取高分辨率的珊瑚样品，从中将测量稳定的氧同位素(0-18/0-16和锶/钙)。样本将在西奈半岛尖端附近获取，那里的温度很高，允许珊瑚快速生长，但PI假设冬季强烈对流会产生深水形成。海面附近的珊瑚样本将与跃层更深的珊瑚样本进行比较。然后，这些数据将被同化到一个包含深对流的红海模型中，以检验这一假设。

9416712 Schrag In this project the PIs will study deep water formation in the Red Sea using geochemical and physical techniques. Geochemical work will involve obtaining high resolution samples corals, from which measurements of stable oxygen isotopes (0-18/0-16 and Sr/Ca) will be made. Samples will be obtained near the tip of the Sinai Peninsula, where the temperature is high, allowing very rapid coral growth, but where the PIs hypothesize that strong winter convection produces deep water formation. Samples of corals near the sea surface will be compared with those at greater depths in the pycnocline. The data will then be assimilated in a model of the Red Sea which includes deep convection, in order to test the hypothesis.
