HUGO: The Hawaii Undersea Geo-Observatory Evaluation

98187993 duennebier提供资金，以评估第一个海底电缆观测站的初步运作，并为其未来制定计划。夏威夷海底地质观测站（HUGO）是一个自动海底火山观测站，位于夏威夷岛基拉韦厄火山以南约50英里的海底Loihi海山山顶，通过光纤电缆与海岸相连。HUGO的设计目的是通过收集各种实验数据来监测Loihi上的活动，这些实验数据将被连接到电缆末端的接线盒上。在1997年10月部署时，这些实验包括一个地震仪、一个水听器和一个压力传感器。其他拟议中的传感器将监测地震和火山喷发、地质学、地球物理学、生物学、热液喷口和海底山的其他活动。该系统运行并收集了7个月的数据，直到1998年4月26日，一次电气故障终止了该系统的运行。七个月的连续海底测量结果将整理出来出版。海底接线盒也将被回收，并将进行一项研究，评估观测站的故障模式，以确定维修或重新安装是否在科学上有保证或在技术上可行。

9818793DuennebierFunding is provided to evaluate the initial operation of the first cabled deep seafloor observatory and to make plans for it futures. The Hawaii Undersea Geo-Observatory (HUGO) was developed and installed as an automated submarine volcano observatory on the summit of the undersea Loihi seamount approximately 50 miles due south of Kilauea volcano on the island of Hawaii It is connected to the shore via fiber optic cable. HUGO was designed to monitor activity on Loihi by collecting data from a variety of experiments that were to be connected to a junction box at the end of the cable. At its deployment in October 1997, these experiments included a seismometer, a hydrophone and a pressure sensor. Other proposed sensors would monitor earthquakes and eruptions, geology, geophysics, biology, hydrothermal venting and other activities on the underwater seamount. The system operated and collected data for seven months, until April 26, 1998, when an electrical failure terminated operations. Seven months of continuous seafloor measurements will be worked up for publication. The seafloor junction box will also be recovered, and a study will be undertaken to evaluate the failure mode of the observatory in order to determine whether a repair or re-installation is scientifically warranted or technically feasible.
