Acquisition of a High-Temperature, Memory Temperature Tool For Use During ODP Drilling at Hydrothermal Sites and During Post-Drilling Submersible Operations at ODP CORK Sites

该项目是购买和修改一种高温（350摄氏度），可编程温度测井工具，用于测量海洋钻井计划船R/V JOIDES Resolution钻探的孔的地下温度。该工具具有地下压力（深度）和温度的内部记录能力，无需特殊的测井电缆即可进行部署，可以快速使用，无需专门的船上仪器或部署能力。将对该工具进行修改，使其能够从DSV Alvin潜水器上使用，并将在计划于1994年9月至11月进行的ODP第158期期间用于测量大西洋中脊热液喷口区域“TAG”钻孔的井下温度。PI Becker将作为井下测井团队的一员参加Leg 158钻井。该工具还将在随后与DSV Alvin一起潜水时使用，以便在1995年期间重新利用TAG海底的这些“软木塞”洞，观察这些地点的温度结构变化。在比赛中，为了这个目的，PI将获得两次阿尔文潜水。该测井工具将在未来提供给其他研究人员用于JOIDES Resolution， DSV Alvin或其他适当的平台。* * *

9402805 Becker This project is to purchase and modify a high-temperature (350 degrees C), programmable temperature-logging tool for use in measuring subsurface temperatures in holes drilled by the Ocean Drilling Program vessel R/V JOIDES Resolution. The tool will have internal recording capability for both subsurface pressure (depth) and temperature, and may be deployed without special logging cable, allowing its use rapidly and without specialized shipboard instrumentation or deployment capabilities. The tool will be modified to allow its use from the submersible DSV Alvin, and it will be used for measuring downhole temperatures at "TAG" drill holes in the hydrothermal vent area on the Mid-Atlantic Ridge during ODP Leg 158, scheduled for September-November 1994. PI Becker will participate in Leg 158 drilling as a member of the downhole logging team. The tool will also be used during subsequent submersible diving with DSV Alvin, to reoccupy these "CORKed" holes in the seafloor at TAG to observe changes in temperature structure at these sites during 1995. Two Alvin dives are awarded to the PI for this purpose in the award. The logging tool will be available to other researchers for use on JOIDES Resolution, DSV Alvin, or other appropriate platforms in the future. ***
