The study of the deep structure and tectonic history of continental margins is an important topic in the earth and ocean sciences. The nature and thickness of crustal layers and the subsidence history determined from data on sediments can be used to determine the strength of the continental crust, as well as to evaluate models for crustal thinning and stretching. The continental margin of the Gulf of Valencia in the western Mediterranean is an ideal location for such a study since this margin has formed relatively recently and has only a thin sediment cover. The present award will support a marine geophysical program to examine the thickness, seismic character and heat flow across this margin. The work will be a cooperative project with French and Spanish scientists, and will utilize a second French research vessel in addition to the R.V. Conrad. These data will be integrated with existing well data and gravity studies of this margin to evaluate the processes occurring during rifting and stretching of continental crust.

大陆边缘深部结构和构造历史研究是地球与海洋科学的重要课题。地壳层的性质和厚度以及根据沉积物数据确定的沉降历史可用于确定大陆地壳的强度，以及评估地壳减薄和拉伸的模型。西地中海巴伦西亚湾大陆边缘是进行此类研究的理想地点，因为该边缘形成时间相对较晚，并且只有一层薄薄的沉积物覆盖。 本奖项将支持一项海洋地球物理计划，以检查该边缘的厚度、地震特征和热流。这项工作将是与法国和西班牙科学家的合作项目，除了 R.V. 之外，还将利用第二艘法国研究船。康拉德.这些数据将与该边缘的现有井数据和重力研究相结合，以评估大陆地壳裂谷和拉伸过程中发生的过程。
