Abstract

From March to May 2019, a seasonal multidisciplinary scientific expedition on the EV Akademik Tryoshnikov was conducted in the framework of the first stage of the “TransArctica 2019” program. Within the seismological part, six temporary seismic stations were installed at four different locations on a drifted ice floe in the North Barents Sea. The first aim of the experiment was to elaborate technology of installation of the seismic stations on drifting ice floes. The second aim was to check if obtained seismological records could be used for registration of the local and remote earthquakes and provide data to investigate the lithosphere structure in the Arctic regions, as well as processes within the ice floe. After analysis of the recoded data, different types of the seismic signal generated by processes in the ice were observed and several signals from remote and regional earthquakes were detected. Further analysis of the seismograms could be used for investigations of the processes within ice floes. The results of the experiment have shown that seismic sensors installed on the drifting ice could be used for recording of local and remote earthquakes.

浮冰上的地震网络：以北巴伦支海为例

摘要

从2019年3月至2019年5月，在EV Akademik Tryoshnikov进行的一次季节性多学科科学考察是在“ TransArctica 2019”计划第一阶段的框架内进行的。在地震部分内，在北巴伦支海的一块浮冰上的四个不同位置安装了六个临时地震台。实验的第一个目的是精心设计在浮冰上安装地震台的技术。第二个目的是检查获得的地震记录是否可用于记录本地和偏远地震，并提供数据以调查北极地区的岩石圈结构以及浮冰内部的过程。在对记录的数据进行分析之后，观察到了冰中过程产生的不同类型的地震信号，并检测到了来自偏远地区地震的几种信号。地震图的进一步分析可用于调查浮冰内的过程。实验结果表明，安装在流冰上的地震传感器可用于记录本地和远程地震。
