9730588 Stephen This award will support the U.S. participation in a joint seismic experiment with scientists from Germany. The objective of the project is to acquire seismic reflection and refraction data from the Ninety-East Ridge in the Indian Ocean. The U.S. scientific component will be responsible for measurements to be recorded in a borehole to be drilled as part of the Ocean Drilling Program. The seismic sources for this experiment will be deployed from a German vessel which will rendezvous with the drillship, JOIDES Resolution, and will be undertaking a regional study of the crustal structure of the ridge. Specific scientific questions being addressed include crustal anisotropy and heterogeneity, and the detailed velocity structure surrounding the drill site which will be the location of a permanent seismic station to be installed by French scientists. ***

9730588斯蒂芬该奖项将支持美国参与与德国科学家的联合地震实验。该项目的目标是获取印度洋90东海脊的地震反射和折射数据。美国科学部门将负责记录作为大洋钻探计划一部分的钻孔中的测量结果。这次实验的地震源将从一艘德国船只上部署，该船将与“JOIDES Resolution”号钻井船会合，并将对海脊的地壳结构进行区域研究。正在处理的具体科学问题包括地壳的各向异性和异质性，以及钻井地点周围的详细速度结构，法国科学家将在该地点安装一个永久性地震站。 ***
