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

该项目将开始对中大西洋海脊进行长期监测，以确定这一缓慢扩展的海脊在各种规模的地震中的地震活动特征。 其目标是获得一个整体地震活动的空间和时间模式的一阶理解，岩浆和构造事件之间的分区，与长期目标，将这些信息纳入模型中的大西洋中脊的蔓延。 六个自主水下水听器将停泊在大西洋中脊两侧北纬15度至35度之间的SOFAR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.
