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.

9403812 WILLIAMSON 该提案寻求第二阶段资金，以完成第一阶段启动的远程控制深海岩心取样工具的可行性评估。所提出的设计利用经过验证的陆地钻探工具和技术，在硬岩和沉积海底的位置获取岩心 50 至 100 m深达4000m。 拟议的演习可以利用目前大多数 UNOLS 船上配备的传统甲板装卸设备从机会船上进行部署。 第二阶段的工作将进行建造、测试和现场试验。 该原型设备将用于获取从软粘土到硬岩基质的多个全尺寸样品。 第二阶段计划的成功完成将导致海底取芯工具的商业化（第三阶段）和全面实施，该工具能够获取以前只能通过钻探船获得的样本。 该钻探提案将为研究界和近海工业提供一种具有成本效益的海底采样技术。
