Intellectual Merit: This proposal is to conduct a number of hydrogeologic experiments in ocean crust on the east flank of the Juan de Fuca Ridge in the Northeast Pacific Ocean. The aim of the experiments is to study the movement of fluids, chemicals and microbes within the ocean crust between drill holes completed by the Integrative Ocean Drilling Program. The work will be the first to run a long-term cross-drill-hole test in the ocean crust. One and two years following the Integrative Ocean Drilling Program expedition in 2010, the down hole instruments will be serviced and samples collected from multiple depths in the hole. Three-dimensional numerical modeling will evaluate how flow works within the oceanic crust. Taken together, the proposed work will constrain heat transport, chemical transport, and sub-seafloor microbiology making the results of value to many communities.Broader Impacts: This project will train graduate and undergraduate students and will leverage off of an existing education and outreach program already in place for the Integrative Ocean Drilling Program expedition in 2010.

智力优势：这项提议是在东北太平洋胡安·德富卡海脊东侧的洋壳中进行一些水文地质实验。实验的目的是研究海洋地壳内的流体，化学物质和微生物在综合海洋钻探计划完成的钻孔之间的运动。这项工作将是第一个在海洋地壳中进行长期交叉钻孔测试的工作。在2010年综合大洋钻探计划考察后的一年和两年，将对井下仪器进行维修，并从孔内多个深度采集样本。 三维数值建模将评估海洋地壳内的流动方式。综合起来，拟议的工作将限制热传输，化学传输，和海底微生物学的结果，使许多社区的价值。更广泛的影响：该项目将培训研究生和本科生，并将利用现有的教育和推广计划已经到位的综合大洋钻探计划探险在2010年。
