Collaborative Research: A Sea Test of the PROD Seafloor Drill

0000717 johnson俄勒冈州立大学与华盛顿大学的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，将允许在超过100米的海底深处取样沉积物，在各种水深和基质中受到最小的干扰。该系统由bentich Geotek有限公司建造和运营，设计用于各种多用途海洋研究船，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井船JOIDES Resolution获得钻探材料。PROD系统使用光纤技术来控制底部安装的钻井系统，它包括使用液压活塞取心的能力，这种技术可以在松散的沉积物中获得很少干扰的样品，以及旋转钻井，可以穿透较硬的沉积物和岩石。这里支持的测试将是该系统首次在深水中运行，以及它在美国学术研究船上的初始操作。在测试过程中获得的任何样本将在俄勒冈州立大学存档，供感兴趣的研究人员将来进行调查

0000717JohnsonThis 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.***
