A Broadband Borehole Seismometer for the Deep Ocean (WHOI Component)

STEPHEN：这份更新合同支持在夏威夷岛附近的海洋钻探计划（ocean Drilling Program）钻探的深海孔（OSN-1）上部署地震仪的仪器开发。总的目标是能够在海底准确和长时间地测量地震活动，以填补主要限于陆地测量的记录世界范围地震活动的主要空白。这些伍兹霍尔海洋研究人员与斯克里普斯海洋研究所的同事们合作，准备并测试了一个适合安装在井眼中的地震仪系统（在陆地上的测试井中）。在目前的工作中，他们将为地震仪准备一个合适的外壳，以承受深海压力，并将设计和建造设备，从海面上的船上将地震仪和数据记录包安装在海底钻孔中。

9505730 STEPHEN This renewal award supports development of instrumentation for deploying seismometers in the deep ocean at a hole (OSN-1) drilled by the Ocean Drilling Program near the island of Hawaii. The overall objective is to enable measurement of seismic activity accurately and over long periods at ocean bottom sites, to fill major gaps in recording worldwide earthquake activity which is primarily limited to land measurements. With their previous award, these Woods Hole Oceanographic Investigators, in collaboration with colleagues at Scripps Institution of Oceanography, have prepared and tested (in a test well on land) a seismograph system suitable for installation in a borehole. In the present work they will prepare a suitable housing for the seismometer to withstand deep- ocean pressures, and will design and build equipment to install the seismograph and data recording package in the ocean bottom borehole from a ship at the sea surface.
