Collaborative Research: A three-dimensional, subseafloor, IODP observatory network in the northeastern Pacific Ocean, and initiation of large-scale, cross-hole experiments

摘要建议： 0550713日期： 01/17/2006该项目将支持设计、建造和获取钻孔仪器，该仪器是目前正在Juan de Fuca山脊东侧建造的水文观测网络的组成部分。作为这项基于工程的工作的一个关键组成部分，研究人员将计划进行实验，以阐明年轻洋壳的三维水力特性和水文地质过程。该项目将导致观测仪器（主要是CORK）的进步，以及用于维护来自海洋平台/HOV平台的仪器钻孔的特殊修改和工具。继2004年中期301号考察期间根据JOIDES决议完成的第一阶段之后，IODP胡安·德富卡裂谷侧翼钻探的第二阶段需要进行这种设计工作。拟议工作的更广泛影响包括促进对海底水文地质学的了解，扩大301远征的科学成果，促进开发更强大的观测仪器，加强物理，化学和生物科学家之间的跨学科合作，以及培训学生。

ABSTRACTPROPOSAL : 0550713 DATE : 01/17/2006 This project will support the design, construction, and acquisition of borehole instrumentation that is an integral component of a hydrologic observatory network currently under construction on the eastern flank of the Juan de Fuca Ridge. As a key component of this engineering-based effort, the researchers will plan experiments to elucidate three-dimensional hydraulic properties and hydrogeologic processes in young oceanic crust. The project will lead to advances in observatory instrumentation (primarily CORKs) and special modifications and tools for servicing instrumented boreholes from ROV/HOV platforms. Such design efforts are required for the second phase of IODP Juan de Fuca rift flank drilling, following on the first phase completed on the JOIDES Resolution during Expedition 301 in mid-2004. Broader impacts of the proposed work include contributing to an understanding of seafloor hydrogeology, augmenting the scientific results from Expedition 301, contributing to the development of more robust observatory instrumentation, enchancing interdisciplinary collaborations among physical, chemical, and biological scientists, and training of students.
