Mass Balance And Accumulation Rate Along Us Itase Routes, Gordon Hamilton

University of Maine Office of Research Administration: Grant Reports

The primary research activities in this project involved our participation in the four US ITASE field seasons (1999-2003). As part of the field program we collected ~5,500 km of continuous, precise GPS data along the traverse route. These geodetic data are used by ourselves and several other US ITASE investigators. We also installed 15 new mass balance (coffee can) stations in rarely visited regions of West and East Antarctica. Several shallow firn cores were collected to study local variability in snow accumulation around deeper 200-year ice core sites. As part of our collaboration with NASA, we performed detailed 3-dimensional mapping …
