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.

在这个项目中，pi将使用地球化学和物理技术研究红海的深水地层。地球化学工作将包括获得高分辨率的珊瑚样本，从中测量稳定的氧同位素（0-18/0-16和Sr/Ca）。样本将在西奈半岛的顶端附近获得，那里温度高，珊瑚生长非常迅速，但pi假设强烈的冬季对流产生深水形成。海面附近的珊瑚样本将与背斜深处的珊瑚样本进行比较。然后，这些数据将被纳入红海的一个包括深层对流的模型中，以检验这一假设。
