Collaborative Research: Construction of a Permanent Geoelectric/Geomagnetic Observatory on the Seafloor

这一海洋科学技术开发项目涉及设计、建造、测试和安装位于夏威夷2号观测站(H2O)的海底地磁观测站，该观测站位于加利福尼亚州和夏威夷之间，位于5000米深的水下。将安装的地磁仪器符合INTERMAGNET数据精度和时间的标准。它将包括一个Delta iDelta D磁力计，一个用于绝对方向测量的陀螺罗盘，一套悬浮磁力变异仪，辅助环境传感器，以及一个利用电极切割技术的单独的地电观测站。电力将由H2O提供，实时、双向通信将允许从陆地控制天文台并将数据传输给用户。该网站的数据将通过INTERMAGNET免费提供给科学界。地磁观测站也将成为未来在其他地点安装的原型。

This ocean science technology development project involves the design, construction, testing, and installation of a seafloor geomagnetic observatory at the Hawaii-2 Observatory (H2O) site located midway between California and Hawaii in 5000 m of water. The geomagnetic instrumentation to be installed meets INTERMAGNET standards for data accuracy and timing. It will consist of a delta Idelta D magnetometer, a gyrocompass for absolute direction measurement, a set of suspended magnet variometers, auxiliary environmental sensors, and a separate geoelectric observatory utilizing electrode chopping techniques. Power will be supplied by H2O and real-time, two-way communications will allow both control of the observatory from land and transmission of data to the user. The data from this site will be made freely available to the scientific community through INTERMAGNET. The geomagnetic observatory will also be a prototype for future installations at other sites.
