This collaborative effort between IRIS, University of Hawaii, Woods Hole Oceanographic Institution and a private corporation will result in a multi-purpose seafloor observatory for geophysical research. The Hawaii-2 undersea telephone cable between Hawaii and California has been retired by AT&T and transferred for scientific re-use by the geoscience community. The initiation of a deep-ocean facility-the Hawaii-2 Observatory (H20)-will provide the capability for long-term geoscientific research at the sea floor using the Hawaii-2 cable for power and two-way, real-time communications. A site midway between Hawaii and California optimizes coverage for the IRIS Global Seismographic Network, and will potentially contribute to geomagnetism, tsunami studies, and physical oceanography. A junction box with eight independent underwater-mateable connectors will be connected to the Hawaii-2 cable. A broadband seismometer and hydrophone package will be deployed (plugged in). Ample power availability to the observatory opens up the types of instrumentation that can be added (or changed) later using a remotely operated vehicle (ROV) or a manned submersible. The data from H20 will be available in real time on a disk buffer via Internet or telephone dial-up. Data will be archived and distributed by the IRIS Data Management Center in Seattle. The seismic station at H20 will become a part of the IRIS Global Seismographic Network.

IRIS、夏威夷大学、伍兹霍尔海洋研究所和一家私人公司之间的合作努力将形成一个用于地球物理研究的多用途海底观测站。夏威夷和加利福尼亚之间的夏威夷-2号海底电话电缆已经被美国电话电报公司（at&t）退役，并转移给地球科学团体进行科学再利用。启动的深海设施——夏威夷-2号天文台（H20）——将利用夏威夷-2号电缆提供电力和双向实时通信，为海底的长期地球科学研究提供能力。夏威夷和加利福尼亚之间的一个站点优化了IRIS全球地震台网的覆盖范围，并可能对地磁、海啸研究和物理海洋学做出贡献。一个带有8个独立的水下兼容连接器的接线盒将连接到夏威夷2号电缆上。宽带地震仪和水听器套件将被部署（插入）。充足的电力供应给天文台打开了仪器的类型，可以添加（或改变）以后使用遥控车辆（ROV）或载人潜水器。来自H20的数据将通过互联网或电话拨号实时存储在磁盘缓冲区上。数据将由位于西雅图的IRIS数据管理中心存档和分发。位于H20的地震台站将成为IRIS全球地震台网的一部分。
