Research Locations: Whillans Ice Plain


This project is the surface geophysics component of the Subglacial Antarctic Lakes Scientific Access (SALSA) project and has been underway for two years. The project's long-term GPS array on the Whillans Ice Plain comprises eight stations that capture subglacial lake activity and the resulting ice dynamics. The long-term array will be supplemented this season by temporary GPS experiments and collection of kinematic GPS data in order to examine important interfaces such as the shoreline of a subglacial lake.

Field Season Overview

Field team members travel by LC-130 aircraft from McMurdo to the Whillans Ice Stream where they will establish a base tent camp for approximately six weeks, making trips by snowmobile to other tent camp locations. They will collaborate with team members from event C-525-M (Schwartz) to remove all seismic equipment and to service and reposition GPS stations. The combined, five-person field team plus a mountaineer will work in three main locations: the ACT ski way/Grounding Zone (put-in location), WG (seismic array location), and WS (seismic array location).
