Abstract

Abstract. Passive seismic measurements allow the study of the deeper Earth beneath the thick Antarctic ice sheet cover. Due to logistical and weather constraints, only a fraction of the area of the Antarctic ice sheet can be surveyed with long-term or temporary sensors. A fundamental limitation is the power supply and operation of the instruments during the polar winter. In addition, there is only a limited time window during the field seasons to deploy the stations over the year. Here we present a rapidly and simple deployable self-sufficient mobile seismic station concept. The station consists of different energy supply modules aligned according to the survey needs, measuring duration, and survey aim. Parts of the concept are integrated into an already existing pool of mobile stations and in the seismological network of the geophysical observatory at Neumayer III Station. Other concepts and features are still under development. The overall goal is to use these temporary mobile arrays in regions where little is known about local and regional tectonic earthquake activity.

建立一个自给自足的移动宽带地震记录系统，以便在南极洲全年运行

摘要被动地震测量可以研究厚厚的南极冰盖下更深的地球。由于后勤和天气的限制，只有南极冰盖的一小部分区域可以用长期或临时传感器进行调查。一个基本的限制是极地冬季仪器的电力供应和操作。此外，在野外季节，全年只有有限的时间窗口来部署这些站点。在这里，我们提出了一个快速和简单的部署自给自足的移动地震站的概念。该站由不同的能源供应模块组成，根据测量需要、测量持续时间和测量目标进行排列。这个概念的一部分被整合到一个已经存在的移动站池和诺伊梅尔国际站地球物理观测站的地震学网络中。其他概念和功能仍在开发中。总体目标是在对当地和区域构造地震活动知之甚少的地区使用这些临时移动阵列。

期刊介绍： Geoscientific Instrumentation, Methods and Data Systems (GI) is an open-access interdisciplinary electronic journal for swift publication of original articles and short communications in the area of geoscientific instruments. It covers three main areas: (i) atmospheric and geospace sciences, (ii) earth science, and (iii) ocean science. A unique feature of the journal is the emphasis on synergy between science and technology that facilitates advances in GI. These advances include but are not limited to the following: concepts, design, and description of instrumentation and data systems; retrieval techniques of scientific products from measurements; calibration and data quality assessment; uncertainty in measurements; newly developed and planned research platforms and community instrumentation capabilities; major national and international field campaigns and observational research programs; new observational strategies to address societal needs in areas such as monitoring climate change and preventing natural disasters; networking of instruments for enhancing high temporal and spatial resolution of observations. GI has an innovative two-stage publication process involving the scientific discussion forum Geoscientific Instrumentation, Methods and Data Systems Discussions (GID), which has been designed to do the following: foster scientific discussion; maximize the effectiveness and transparency of scientific quality assurance; enable rapid publication; make scientific publications freely accessible.
