I regularly teach courses at the introductory level (Oceanography and Antarctic Geology), intermediate level (Principles of Sedimentation and Stratigraphy) and the graduate level (Glacial Geology).
Overall my research focuses on understanding the history of the Antarctic ice sheet so we can better determine what causes it to advance and retreat and how that fits in with the global climate system. I have several active grants through the National Science Foundation that have provided opportunites for us to collect field data, which provides important new data to help us determine Antarctica's history. One project builds on our previous work in the Ross Sea (Licht et al., 2014) and includes provenance analysis of glacial sediments in the Weddell Sea region of Antarctica. A second grant provided funding for us to collect radar data that lets us see beneath the ice surface and characterize the internal structure of the ice. The glacial deposits at this research site are unusual in that they contains a relatively continuous sequence of glacial deposits spanning more than one glacial-interglacial cycle, allowing us to document ice sheet changes on these long time scales. If you want to know more about our field seasons, you can scroll back through our Twitter account (@IUPUIonice).
The scientific objectives of our work dovetail with an international effort strongly focused on studying and modeling Antarctic ice sheet history, in part because of its potential impact on global sea level rise. The variation of till compositions through time also allows for better down core interpretation of cores from the Ross Sea and the Southern Ocean. Additionally, till exposures at the head of some East Antarctic outlets have been shown to contain subglacial material derived from East Antarctic bedrock, providing a window through the ice with which to view East Antarctica’s inaccessible bedrock.
