Selected Works of Gordon S. Hamilton

Associate Research Professor of Earth Sciences

I am interested in ice sheet mass balance and the role ice sheets play in modulating global sea levels. This research currently involves field work in Greenland and Antarctica, using GPS to study ice flow dynamics and GPR to understand snow accumulation, as well as satellite remote sensing of both ice sheets and other glacierized regions. I am also interested in the promoting the public understanding of climate change science.
