Description
Summary:This archive contains magnetotelluric (MT) responses estimated from MT time series data that were collected to study subglacial groundwater beneath Whillans Ice Stream, West Antarctica. Data acquisition took place during the 2018/2019 Antarctic summer field season. 27 MT stations were collected at Whillans Subglacial Lake (SLW) and 16 stations were obtained at its hypothesized downstream outlet to the ocean, Whillans Grounding Zone (WGZ). The MT responses are provided as text files in the *.zmm* format output by the MT data processing code, but have also been converted to the more widely used *.edi* text file format for convenience. All sensor orientations are listed as geomagnetic azimuths, which for this region are substantially different than the corresponding geographic azimuths.
