My doctoral research identified the processes driving increases and decreases in mass loss at a tidewater glacier in Alaska, as well as how glacier seismology can inform our understanding of iceberg calving. This research drew on field data collected on the coast of Alaska, in the St. Elias Range, specifically Yahtse Glacier and Icy Bay, the fjord into which Yahtse terminates. This project was led by Chris Larsen and Mike West from the University of Alaska Fairbanks, and Shad O’Neel from the U.S. Geological Survey. This work was funded by the National Science Foundation.
