Project Description:
The Center for Remote Sensing of Ice Sheets (CReSIS) researchers will measure the melt rate beneath the Ross Ice Shelf at a number of locations using a phase-sensitive ground-based radar system. By accurately measuring the change in thickness of the ice shelf at two or more times (separated by a few weeks), researchers can estimate the basal melt rate, which is important for glacier-flow modeling, ice-sheet stability, and ocean-water circulation beneath ice shelves. In the time between flight periods, researchers will conduct ground-based seismic and radar measurements on and around the main CReSIS camp.

Field Season Overview:
A three-person team will fly from the main Cresis camp on Whillans Ice Stream (B) to various locations on the Ross Ice Shelf and grounded ice sites. The radar system will be used to accurately measure the ice thickness, and then the same sites will be re-measured after a few weeks. At each site a seismic line will be occupied to determine water thickness. Time on site will be a few hours. In between these week-long periods of flying the I-188 team will conduct ground based seismic and radar work around the main CReSIS camp.

Deploying Team Members:

  • Sridhar Anandakrishnan (Co-PI)
  • Peter Burkett
