OCE 99-11962TaylorAward is for a geophysical study of the western and central Gulf of Aden conjugate continental margins to define the tectonic, stratigraphic, and magmatic development of one of the world's key areas for understanding how the initiation of continental rifting proceeds. Deep-penetration, multi-channel reflection and Ocean Bottom Seismometer (OBS) refraction data, swath bathymmetry, magnetic, and gravity data will be collected in support of the objectives, which are centered around determining how the Afar mantle plume has affected the development of continental breakup and rift-flank structural development in the Gulf of Aden area. Specifically, variation of strain partitioning, magmatism, and crustal structure with variation of distance from the Afar plume will be examined in the course of reconstructing conjugate margin evolution. This work will also serve as a site survey in support of the ODP pre-proposal 528-Pre, and addresses an important goal of the ODP Long Range Plan, that of understanding early conjugate-margin development and continent-ocean transitions.***

OCE 99-11962泰勒奖旨在奖励亚丁湾西部和中部共轭大陆边缘的地球物理研究，以定义世界关键地区之一的构造、地层和岩浆发育，从而了解大陆裂谷的启动如何进行。 将收集深穿透、多通道反射和海底地震仪（OBS）折射数据、条带测深、磁力和重力数据以支持目标，其重点是确定阿法尔地幔柱如何影响亚丁湾地区大陆破裂和裂谷侧翼结构发育的发展。 具体来说，在重建共轭边缘演化的过程中，将检查应变分配、岩浆活动和地壳结构随距阿法尔地幔柱距离的变化而变化。 这项工作还将作为支持 ODP 预提案 528-Pre 的现场调查，并实现 ODP 长期计划的一个重要目标，即了解早期共轭边际发展和大陆-海洋转变。***
