McMurdo Ice Shelf GPS survey of vertical motion

Over 2 Austral summer periods in 2015/6 and 2016/17, up to 12 geodetic GPS receivers were deployed on the McMurdo Ice Shelf to study its vertical deflection in response to moving meltwater loads. (5 GPS were deployed in 2015/16, 12 in 2016/17.) The GPS receivers and antennas were supplied by UNAVCO...

Description
Summary:Over 2 Austral summer periods in 2015/6 and 2016/17, up to 12 geodetic GPS receivers were deployed on the McMurdo Ice Shelf to study its vertical deflection in response to moving meltwater loads. (5 GPS were deployed in 2015/16, 12 in 2016/17.) The GPS receivers and antennas were supplied by UNAVCO and were Trimble NetR9’s and Zephyr Geodetic, respectively. The GPS receivers were stationary for the entire field seasons (were never moved). Following each field season, the GPS data were processed using MIT software called TRACK, which is part of the GAMIT package. The UNAVCO-run base station at McMurdo Station, approximately 16 km away from the field area, was used as part of the processing.
