Award is for a project to install the first operational borehole seismometer in the deep ocean at the Hawaii-2 Observatory site. ODP Leg 200 drilled and cased a re-entry hole for this purpose during December 2001. This project will develop and test an improved seismic sonde, and develop a method and apparatus to lay a fiber optic cable from the borehole1.5 km to the Hawaii-2 Observatory junction box, using a deep submergence ROV. In addition, a thermistor string will placed in a nearby, uncased hole. After installation of the seismometer, it will be tested and validated by comparison with land-based seismometers and with a seismometer located on the sea bed at the H2O site.

该项目将在夏威夷2号天文台的深海中安装第一个可操作的钻孔地震仪。2001年12月，ODP Leg 200为此钻了一个再入井并下了套管。该项目将开发和测试一种改进的地震探空仪，并开发一种方法和设备，使用深潜式ROV从1.5公里的钻孔铺设光纤电缆到夏威夷-2天文台的接线盒。此外，热敏电阻串将放置在附近的无套管孔中。地震仪安装完毕后，将会与地面地震仪及海底地震仪进行对比测试和验证。
