Session Proposal: Rates of Accumulation and Turnover of Terrestrial and Aquatic Carbon Pools: How Are They Influenced by Natural and Anthropogenic Climate Change and Other Factors? Posters (2015 AGU Fall Meeting)

B11H:
Rates of Accumulation and Turnover of Terrestrial and Aquatic Carbon Pools: How Are They Influenced by Natural and Anthropogenic Climate Change and Other Factors? Posters

Session ID#: 9127

Session Description:

Carbon pools both in the terrestrial and the aquatic realm are critical to the future CO2 and CH4 content of the atmosphere. The fate of these carbon pools and the rate of change is key to understanding how rapidly our planet will warm. We seek to encourage talks and posters that focus on our knowledge of the influence of temperature, precipitation, pH, nutrients, ecology, sea level rise, etc. on rates of change of terrestrial and aquatic C pools. Modern and paleo field data, lab experiments, and modeling are welcome.
