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

9416712 Schrag在该项目中，项目研究员将利用地球化学和物理技术研究红海深水的形成。 地球化学工作将包括获取高分辨率珊瑚样本，从中测量稳定氧同位素（0-18/0-16和Sr/Ca）。 样品将在西奈半岛半岛尖端附近采集，那里的温度很高，珊瑚生长非常迅速，但研究人员假设那里的冬季对流很强，会形成深水。 将把海面附近的珊瑚样品与密度跃层更深处的珊瑚样品进行比较。 然后将把这些数据同化到一个包括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.
