9403812 WILLIAMSON This proposal seeks Phase II funding to complete the feasibility assessment for the remote control deepsea core sampling tool initiated in Phase I. The design presented utilizes proven land drilling tools and techniques to obtain cores 50 to 100m into hard rock and sedimented seafloors at locations as deep as 4000m. The proposed drill can be deployed from ships-of-opportunity utilizing conventional deck handling equipment currently available on most UNOLS vessels. The Phase II effort will construct and test and field trials. The prototype device will be used to obtain multiple, full-scale samples from soft clays to hard rock substrate. The successful completion of the Phase II program will lead to the commercialization (Phase III) and full implementation of a seafloor coring tool capable of obtaining samples previously available only through use of a drill ship. The proposal drill will provide a cost effective seafloor sampling technology to the research community and offshore industry.

威廉姆森9403812 本提案寻求第二阶段的资金，以完成第一阶段启动的遥控深海岩心取样工具的可行性评估。 所提出的设计利用成熟的陆地钻探工具和技术，在4000米深的硬岩和沉积海底中获得50至100米的岩心。 拟议的演习可以利用联合国后勤支助处大多数船只现有的常规甲板装卸设备从"机会“船上进行。 第二阶段的工作将建造和测试和实地试验。 原型设备将用于获得从软粘土到硬岩石基底的多个全尺寸样品。 第二阶段计划的成功完成将导致商业化（第三阶段）和海底取芯工具的全面实施，该工具能够获得以前只能通过使用钻探船获得的样品。 该提议的钻探将为研究界和海上工业提供一种具有成本效益的海底取样技术。
