Evaluating processes at and near marine-ending glaciers in Alaska (A), Chile (B) and Antarctica (C) to 1) evaluate their stability during global climate change, 2) determine the type of sedimentary record that these glaciers would leave in order to infer past glacial/climatic condition from older deposits and 3) conduct marine geology and geophysical studies of Cenozoic sediments on continental shelves to document past glacial fluctuations through time.
I teach a variety of courses for undergraduate non-majors, undergraduate and graduate students majoring in geology. This table provides a listing of the courses I teach, as well as a copy of the most recent syllabus for each course, and the description of the course that appears in the NIU course catalog.
