分布式声学传感（DAS）作为一种在密集阵列配置中记录地震信号的有前景的技术，正在各种环境中得到探索。人们对在海底部署 DAS 阵列特别感兴趣，这给传统地震学带来了巨大的挑战。 2022 年 7 月，利用加利福尼亚州蒙特利湾蒙特利湾加速研究系统 (MARS) 52 公里海上电缆上可用的暗光纤，我们在电缆的岸端安装了 DAS 询问器，旨在获取为期一年的连续数据。在这里，我们描述了该实验并提供了部署前六个月的观察示例。
Distributed acoustic sensing (DAS) is being explored in a variety of environments as a promising technology for the recording of seismic signals in dense array configurations. There is a particular interest for deploying DAS arrays on the ocean floor, presenting formidable challenges for conventional seismology. Taking advantage of the availability of a dark fiber on the Monterey Bay Accelerated Research System (MARS) 52 km offshore cable at Monterey Bay, California, in July 2022, we installed a DAS interrogator at the shore end of the cable with the intention of acquiring continuous data for a period of one year. Here, we describe the experiment and present examples of observations over the first six months of the deployment.
