Studies of the surface strain of Erebus Glacier Tongue to determine the process of calving
Listed in NASA Earthdata CMR
The surface deformation of the Erebus Glacier Tongue was measured in order to elucidate the calving mechanisms for the formation of icebergs.
Description
Surface strain, surface tilt, surface velocity and long term strain data were measured. 14 depths were measured by plumb line on the sea ice. Two sites on the sea ice were used to measure the amplitude of the wave swell penetrating the glacier in open water.
Simultaneous observations of the glacier oscillations and wave amplitude on the sea ice were made to deduce the energy transfer function between the sea and the glacier. Elevation was measured with an altimeter and cairns built. The NSF-SPRI-TUD radio echo sounding team made a flight along the glacier to provide a longitudinal profile.

An 11m core was retrieved from the glacier surface and used to determine a density-depth profile. A 1m core was also collected from an area of blue ice. Temperature measurements were made in the 11m hole and in a number of crevasses.
