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

该项目将支持钻孔仪器的设计、建造和采购，钻孔仪器是目前在胡安德富卡山脊东侧建设的水文观测网的一个组成部分。作为这项基于工程的努力的关键组成部分，研究人员将计划进行实验，以阐明年轻洋壳中的三维水力特性和水文地质过程。该项目将导致观测站仪器(主要是软木塞)的进步，以及为ROV/HOV平台的仪表孔提供服务的特殊改装和工具。这种设计工作是IODP Juan de Fuca裂谷侧翼钻探第二阶段所需的，第一阶段是2004年年中在第301次远征期间根据JOIDES决议完成的。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，加强第301次探险的科学成果，促进开发更强大的观测台仪器，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.
