Collaborative Research: A Sea Test of the PROD Seafloor Drill

79912345金手指该奖项授予俄勒冈州州立大学，与华盛顿大学合作，将为海洋学研究的测试仪器提供支持，特别是海底钻探系统PROD，如果成功，将允许对超过100米深的沉积物进行采样，同时对各种水深和基底的干扰最小。 该系统由Benthic Geotek有限公司建造和运营，设计用于从各种多用途海洋研究船上操作，大大增加了获取钻探材料的机会，目前大多数美国海洋研究人员只能通过海洋钻探计划钻探船JOIDES Resolution获得。 PROD系统使用光纤技术控制一个底部安装的钻探系统，它包括使用液压活塞取芯的能力，这是一种在松散沉积物中几乎不受干扰的情况下获取样本的技术，以及旋转钻探，这使得较硬的沉积物和岩石能够穿透。 此次测试将是该系统首次在深水中运行，也是首次在美国学术研究船上运行。 在测试项目期间获得的任何样本将在俄勒冈州州立大学存档，供感兴趣的研究人员将来调查。*

79912345GoldfingerThis award to Oregon State University in collaboration with University of Washington will provide support to test instrumentation for oceanographic research, specifically a seafloor drilling system, PROD, that if successful will allow sampling of sediments to depths greater than 100 meters subbottom with minimal disturbance in a variety of water depths and substrates. The system, built and operated by Benthic Geotek, Ltd., is designed to operate from a variety of multipurpose oceanographic research vessels, substantially increasing opportunities for acquisition of drilled material, which is presently accessible to most US marine researchers only via the Ocean Drilling Program drillship JOIDES Resolution. The PROD system uses fiber-optic technology to control a bottom-mounted drilling system, and it includes capability to use hydraulic piston coring, a technique to acquire samples with little disturbance in unconsolidated sediments, as well as rotary drilling, which allows penetration of harder sediments and rock. The testing supported here will be the first time the system is operated in deep water, as well as its initial operation from a US academic research vessel. Any samples obtained during the test program will be archived at Oregon State University for future investigation by interested researchers.***
