HUGO - The Hawaii Undersea Geo-Observatory

为继续开发和安装一个海底天文台提供了新的资金，该天文台通过光缆与陆上实验室相连。夏威夷海底地球观测站(HUGO)集成了海洋光缆和潜水技术，为海洋科学界提供了一个位于洛伊希海山顶海底的无人实验室。Loihi是一座海底活火山，位于夏威夷岛东南约35公里处。它的浅山顶(海平面以下约1000米)、令人兴奋的地质、地震、频繁的火山活动以及靠近陆地，使其成为安装永久地球实验室并开始实时监测海底过程的理想地点。这个模块化的天文台有可能容纳来自各个海洋科学学科的100多个实验，为实验提供电力、指挥能力和实时连续的数据传输到岸上。一旦安装，科学家将能够连续研究海底火山、生物和海洋过程。雨果数据还将被美国地质调查局夏威夷火山观测站用于研究夏威夷火山，并被太平洋海啸预警中心用于表征远距离地震引发的海啸。雨果地震和声学数据将提供给当地学校用于教学和项目，子集将在互联网上展示。最初的实验将包括一个以42 kHz采样的宽带水听器，它将对广泛音频范围内的生物和其他噪声敏感。利用电缆将海底观测站和实验场与岸上连接起来，是海洋科学界几个派别非常感兴趣的领域。从这个项目中学到的东西也将应用于未来的电缆安装。

Renewed funding is provided to continue development and install an undersea observatory that is connected to shore-based laboratories via a fiber-optic cable. The Hawaii Undersea Geo-Observatory (HUGO) integrates marine fiberoptic cable and submersible technologies to prmvide the ocean science community with an unmanned laboratory on the ocean floor at the summit of Loihi seamount. Loihi, an active submarine volcano, is located about 35 km southeast of the Island of Hawaii. Its shallow summit (about 1000m below sea level), exciting geology, earthquakes, frequent volcanic activity, and proximity to land make it an ideal site to install a permanent geo-laboratory, and begin real-time monitoring of processes occurring at the ocean floor. The modular observatory has the potential to house more than 100 experiments from every ocean science discipline, supplying experiments with electrical power, command capability, and real-time continuous data transmission to shore. Once installed, scientists will be able to study submarine volcanic, biological, and oceanographic processes continuously. HUGO data will also be used by the U.S. Geological Survey Hawaiian Volcano Observatory in their studies of Hawaiian volcanoes, and by the Pacific Tsunami Warning Center in characterization of tsunamis from distant earthquakes. HUGO earthquake and acoustic data will be made available to local schools for teaching and projects, and sub-sets will be presented on the INTERNET. Initial experiments will include a broad band hydrophone sampled at 42 KHz, which will be sensitive to biological and other noises over a wide range of audio frequencies. The use of cables to connect seafloor observatories and experimental sites to shore is a strong area of interest for several factions of the ocean science community. What is learned from this project will have applications for future cable installations as well.
