This course is a detailed examination of Earth’s geochemical cycles, including inorganic and organic geochemistry. We will use review papers, original scientific works and a textbook to cover a range of areas. Topics include global biogeochemical cycles of carbon and nitrogen, estuarine cycling of organic matter, nutrients and metals, redox cycles, and sediment biogeochemistry/ diagenesis. Course grading is based on 2 exams during the semester, problem sets, paper discussions, and final exam.
