Collaborative Research: Real-Time Volcanic Event Detection on Northeast Pacific Spreading Centers Using Military Hydrophone Arrays

继续1991年开始的时间序列，研究人员将利用北太平洋的美国海军水听器阵列(SOSUS)进行一系列与海脊过程相关的地震/声学研究。通过分析水听器记录的T相数据，研究人员将研究戈尔达、胡安德·富卡和探索者山脊系统上的地震事件，编制环北太平洋地区的小地震目录，将地震事件与山脊顶端的构造/生物变化联系起来，并监测深海的鲸目动物和人为噪音。该项目的一个基本目标是提供数据，以便在RIDGE2000时间关键研究计划的支持下进行快速反应巡航。该项目将结合连续监测和个别巡航，测量胡安德富卡山脊的喷口化学和生物过程，从而可能在地震形变的时空分布与化学和生物事件之间建立联系。更广泛的影响包括为RIDGE2000社区提供服务、对学生进行培训、通过构建水听器计划进行推广、加强与美国政府合作伙伴(美国海军和NOAA)的合作，以及延续一系列可能最终被证明对天文台工作很重要的时间序列。

Continuing a time series that commenced in 1991, the researchers will take advantage of a U.S. Navy hydrophone array (SOSUS) in the North Pacific to conduct a range of seismic/acoustic studies relevant to ridge crest processes. By analyzing T-phase data recorded at the hydrophones, the researchers will study seismic events on the Gorda, Juan de Fuca, and Explorer ridge systems, compile a catalog of small earthquakes in the circum-North Pacific region, link seismic events to tectonic/biological changes at the ridge crests, and monitor cetacean and anthropogenic noise in the deep ocean. A fundamental goal of the project is to provide the data on which to base rapid response cruises under the auspices of the RIDGE2000 time-critical studies program. The project will be coupled with both continuous monitoring and individual cruises that will measure vent chemistry and biological processes at the Juan de Fuca ridge crest, thus making possible potential links between the spatiotemporal distribution of seismic deformation and chemical and biological events. Broader impacts include service to the RIDGE2000 community, training of students, outreach through the build-a-hydrophone program, strengthened collaboration with U.S. government partners (U.S. Navy and NOAA), and continuation of a time series that may eventually prove important to observatory efforts.
