Research Locations: Beardmore Glacier
Researchers will conduct a suite of experiments to study spatial and temporal variations of basal conditions beneath Beardmore Glacier, an East Antarctic outlet glacier that discharges into the Ross Sea Embayment. Measurements include: (1) airborne and surface-based radar to map the ice thickness and geometry of the sub-glacial trough; and (2) active and passive seismic experiments, together with ground-based radar and GPS measurements to map spatial and temporal variations of conditions at the ice-bed interface. The observational data will be used to constrain dynamic models of glacier flow.
Field Season Overview:
Team members will conduct airborne and ground-based radar, seismic and GPS measurements on Beardmore Glacier. Airborne radar surveys will be conducted to fill in gaps in our preliminary map of bed topography. Ground-based measurements this season will focus on the downstream end of the glacier near the grounding line. The team will spend about six weeks conducting active and passive seismic experiments and collecting about 100 km of gridded radar data.
