Long-Term Monitoring of Seismicity at the Mid-Atlantic Ridge using Autonomous Underwater Hydrophones

该项目将启动对中大西洋海脊的长期监测，以确定这一缓慢扩展的海脊在各种事件规模上的地震活动。其目标是对总体地震活动的空间和时间模式以及岩浆活动和构造事件之间的划分有一个初步的了解，长期目标是将这些信息纳入大西洋中脊的扩散模型。六个自动水下水听器将停泊在大西洋中部海脊两侧北纬15度至35度的遥远声道内。该阵列将部署两年。

This project will initiate long-term monitoring of the Mid-Atlantic Ridge to characterize the seismicity of this slow-spreading ridge over a wide range of event sizes. The goal is to obtain a first-order understanding of the spatial and temporal patterns in overall seismicity, and the partitioning between magmatic and tectonic events, with the long-term goal of incorporating this information into a model for spreading at the Mid-Atlantic Ridge. Six autonomous underwater hydrophones will be moored within the SOFAR sound channel between 15 degrees and 35 degrees north on the flanks of the Mid-Atlantic Ridge. The array will be deployed for two years.
