Office Hours: Tuesdays 11 am - noon, or by appointment

Course details

Schedule: Tues / Thurs, 9:30 - 11 am

Textbook:  NO TEXTBOOK REQUIRED. Readings will be made available.

This course examines the processes that control the planetary cycles of carbon, nitrogen and other important elements, the human perturbation of these biogeochemical cycles, and the consequences for the atmosphere, terrestrial ecosystems, and aquatic ecosystems. Topics include the carbon, nitrogen and phosphorus cycles; greenhouse gases and climate change; biological productivity and nutrient limitation in different systems. Link to course syllabus.

DISCUSSION DETAILS: See list of DISCUSSION GROUPS. Discussion leaders review the DISCUSSION GUIDE. The top discussion review from each week will be made available on the website.
