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

9402805贝克尔该项目将购买和改装一台高温(350摄氏度)可编程温度测井仪，用于测量海洋钻探计划船只R/V JOIDES RESOLUTION钻孔的地下温度。该仪器将具有地下压力(深度)和温度的内部记录能力，并且可以在没有特殊测井电缆的情况下部署，从而使其能够快速使用，并且没有专门的船上仪器或部署能力。该仪器将经过改装，以便在潜水器DSV Alvin上使用，并将用于在定于1994年9月至11月进行的第158航次的ODP158航段期间，在大西洋中部海脊的热液喷口区域的“TAG”钻孔测量井下温度。皮贝克尔将作为井下录井队的一员参加158井段的钻井。该工具还将在随后的潜水过程中与dsv Alvin一起使用，以重新利用TAG海底的这些用软木塞堵塞的洞，以观察这些地点在1995年期间的温度结构变化。在奖项中，两次阿尔文潜水被授予PI为此目的。该测井仪器将可供其他研究人员在未来的JOIDES分辨率、DSV Alvin或其他适当的平台上使用。***

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. ***
