Ecosystem project Due Dec 2 This assignment will be somewhat different from your previous assignments in that you will not report on a specific paper, but rather you will put together a quantification of some aspects of global or ecosystem level biogeochemical cycles. Some of these can be group efforts and some individual efforts. You will present quantitative data on the amounts of the material you choose in all the compartments relative to the scaly of the system you pick. You will identify and describe, both in terms of biogeochemical pathways and quantitatively) the fluxes of the material you pick and you will summarize how your results fit into the planet's global biogeochemical dynamics. Here is a sign-up sheet to pick your topic A. Water cycle 1. Quantitative predictions for changes in global hydrological cycle under conditions of global climate change 2. Predictions for ice volumes under conditions of global climate change B. Carbon cycle 3. Atmospheric global carbon cycling 4. Oceanic global carbon cycling today 5. Oceanic global carbon cycling under conditions of global climate change 6. Freshwater global carbon cycling today 7 Freshwater global carbon cycling under conditions of global climate change 8 Soil and global carbon cycling today 9. Soil and global carbon cycling under conditions of global climate change C. Oxygen cycle 10. Changes in atmospheric oxygen dynamics under conditions of global climate change D. Nitrogen 11. Global scale aerobic microbial nitrogen dynamics 12. Global scale anaerobic microbial nitrogen dynamics 13. Species of nitrogen in the atmosphere and global change 14. Effects of atmospheric nitrogen on terrestrial and aquatic systems under conditions of global climate change 15. Nitrogen dynamics in the sea 16. Nitrogen dynamics in wetlands 17 Nitrogen dynamics in soil E Sulfur 18 Global scale sulfur cycling today 19 Global scale sulfur cycling under conditions of global climate change
