0527215DriscollAbstractThe PI will attempt a series of numerical experiments to examine the depth-dependent extension and consequent subsidence of the lithosphere during late stage of continental rifting and early seafloor spreading. Lithospheric thinning, margin breakup and seafloor spreading will be modeled. The PI will explore three alternative hypotheses put forward to explain depth-dependent extension.The work could lead to better insight about how hydrocarbons accumulate and evolve on divergent margins. Scripps Institutions aquarium outreach for K-12 students and science interest in the community and the support of a female co-PI as a post-doc are other broader impacts of this project.

0527215DRISCOLLABSTRACTTHET THE PI将尝试进行一系列数值实验，以检查大陆裂口的后期和早期海底扩散期间岩石圈的深度依赖性延伸和随之而来的沉降。岩石圈稀疏，边缘破裂和海底扩散将进行建模。 PI将探索提出的三个替代假设，以解释深度依赖性扩展。这项工作可能会更好地了解碳氢化合物如何在发散边缘积累和进化。 Scripps机构针对K-12学生的水族馆外展和对社区的科学兴趣，而女性Co-Pi作为大约一名后的支持是该项目的其他更广泛的影响。
