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
The SALSA project has an array of eight continuous GPS stations installed on the Whillans Ice Plain. These GPS stations provide observations of subglacial lake activity and coupled ice stream dynamics. For the 2017-18 season, the team will download data from each station and work to ensure continued data collection for the next 12 months (including the physical installation, maintenance of power systems, and operation of related electronics). Two participants will be based at Shackleton Camp (SHG) for one to two weeks to visit each GPS station by Twin Otter aircraft. Transit time between SHG and the study site is approximately 45 minutes. It is estimated that the team will require one to three hours of ground time at each of the eight GPS sites, resulting in a total of four Twin Otter missions.
