Supporting Stations:  McMurdo Station
Research Locations:  Cape Crozier / Inexpressible Island / Taylor Valley / Minna Bluff

Project Description:
This project seeks to improve our understanding of the last deglaciation of the Ross Sea sector by developing new geochronologic constraints with in situ cosmogenic nuclides and simulating the ice-sheet recession using a state-of-the-art model of the Antarctic Ice Sheet. The field work will include sampling boulders in the McMurdo Sound region (Hjorth Hill, near Blue Glacier, Ross Island, and Minna Bluff).

Field Season Overview:
Project participants will occupy tent camps on Hjorth Hill, near Blue Glacier, and Minna Bluff for approximately five days in each location, with camp moves by helicopter. The field team will also make daily helicopter trips to Capes Bird, Royds, and Crozier.

Deploying Team Members:

  • Peter Clark (PI)
  • Mark Kurz (Co-PI)
