HUGO: The Hawaii Undersea Geo-Observatory Evaluation

9818793Duennebier提供资金，以评估第一个电缆深海底观测站的初步运作，并为其未来制定计划。夏威夷海底地质观测站（HUGO）是一个自动化海底火山观测站，位于夏威夷岛基拉韦厄火山正南约50英里处的洛伊希海底山山顶，通过光纤电缆连接到海岸。HUGO的设计目的是通过收集各种实验的数据来监测Loihi上的活动，这些实验将连接到电缆末端的接线盒。 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。其他拟议的传感器将监测地震和火山爆发、地质学、地球物理学、生物学、热液喷发和水下海山的其他活动。该系统运行并收集了7个月的数据，直到1998年4月26日，当电力故障终止操作。7个月的连续海底测量结果将整理出版。海底接线盒也将被收回，并将进行一项研究，以评估观测台的故障模式，以确定修理或重新安装是否有科学依据或技术上可行。

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.
