Towards a self-sufficient mobile broadband seismological recording system for year-round operation in Antarctica

[摘要] Passive seismic measurements allow the study of the deeper Earthbeneath the thick Antarctic ice sheet cover. Due to logistical and weatherconstraints, only a fraction of the area of the Antarctic ice sheet can besurveyed with long-term or temporary sensors. A fundamental limitation isthe power supply and operation of the instruments during the polar winter.In addition, there is only a limited time window during the field seasons todeploy the stations over the year. Here we present a rapidly and simpledeployable self-sufficient mobile seismic station concept. The stationconsists of different energy supply modules aligned according to the surveyneeds, measuring duration, and survey aim. Parts of the concept areintegrated into an already existing pool of mobile stations and inthe seismological network of the geophysical observatory at Neumayer IIIStation. Other concepts and features are still under development. Theoverall goal is to use these temporary mobile arrays in regions where littleis known about local and regional tectonic earthquake activity.
