Collaborative research: Large-scale, long-term, multi-directional, cross-hole experiments in the upper oceanic crust using a borehole observatory network

本提案将于2010年7月至9月在Juan de Fuca Ridge东侧的浅海地壳中进行水文地质实验，使用安装在IODP钻孔中的钻孔仪器。这项拟议的工作将首次在海洋地壳中进行长期的跨井水文地质测试。这些数据将用于研究浅海地壳内的流体和微生物特征及其关系。三维数值模拟将评估地壳内的流体-热-化学耦合流动。更广泛的影响该项目将培训研究生和本科生，还包括一项主要的外展工作，该外展工作利用了2010年IODP考察团现有的教育和外展计划。

Intellectual MeritThis proposal is to conduct hydrogeologic experiments in shallow ocean crust on the east flank of the Juan de Fuca Ridge using borehole instruments installed in IODP drill holes on Expedition 327, July-September, 2010. The proposed work will be the first to run a long-term cross-well hydrogeologic test in ocean crust. The data will be used to examine fluid and microbial characteristics within the shallow ocean crust and their relationships. Three-dimensional numerical modeling will evaluate coupled fluid-thermal-chemical flow within the crust.Broader ImpactsThis project will train graduate and undergraduate students and also includes a major outreach effort that leverages off of an existing education and outreach program already in place for an IODP expedition in 2010.
