Description

This project aims to place constraints on interior West Antarctic Ice Sheet (WAIS) elevations during the mid-Pliocene, when atmospheric carbon dioxide levels were similar to today's. Researchers will collect surface and subglacial bedrock samples over the course of this two-year project for analysis of cosmogenic nuclides.


Field Season Overview

Team members will travel by LC-130 aircraft to Shackleton Glacier Camp. From there they will fly by Twin Otter and Basler aircrafts to their field camp location in the Ohio Range. They will use snowmobiles to move their drilling equipment from the camp put-in site to the field site, and to conduct their Ground Penetrating Radar (GPR) work. Other work this season will include sampling subglacial bedrock using the new Ice Drilling Design and Operations (IDDO) Winkie drill, which has been modified for this purpose. Collected rock samples will be shipped to the home institution for further analyses.
