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

小行星9505730 该续约合同支持在夏威夷岛附近的大洋钻探计划钻探的一个孔（OSN-1）的深海部署地震仪的仪器开发。 总的目标是能够准确和长期地测量海底地点的地震活动，以填补在记录主要限于陆地测量的全球地震活动方面的主要空白。 这些伍兹霍尔海洋学调查员与斯克里普斯海洋学研究所的同事合作，利用他们以前的奖项，准备并测试了（在陆地上的测试井中）适合安装在钻孔中的地震仪系统。 在目前的工作中，他们将为地震仪准备一个适当的外壳，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.
