Collaborative Research: A Sea Test of the PROD Seafloor Drill

这个奖项授予俄勒冈州立大学与华盛顿大学合作，将为海洋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，将允许在各种水深和基质中以最小的干扰对海底100米以下的沉积物进行采样。该系统由海底地质技术有限公司建造和运营，旨在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井船JOIDES分辨率获得钻探材料。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，这是一种在松散的沉积物中几乎不受干扰地获取样品的技术，以及旋转钻井，它允许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操作，以及它在美国学术研究船上的初步操作。在测试过程中获得的任何样本都将在俄勒冈州立大学存档，以供感兴趣的研究人员未来进行调查。

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.***
