(Winter, 2012). Global-scale biogeochemical cycles, fluxes, and reservoirs in the solid earth, oceans, biosphere, and atmosphere. Provides an introduction to the hydrologic cycle, weathering and erosion, soil formation, nutrient cycling and limitation, ecosystem function and metrics, photosynthesis, carbon and nitrogen cycle dynamics, atmospheric trace gases, and stable-isotope tracers. Includes studies of variability in biogeochemical cycles over Earth history, and recent modifications by human activities. Problem sets require basic scripting in MatLab. Prerequisite: ESE 101,102 or permission of the instructor. Class meets MWF 11-11:50am in Arms 251.
