Dear Colleagues, We would like to encourage you to submit an abstract for the following session at the AGU Fall Meeting (December 5-9, 2011):
B47: Measurement and Modeling of N2O Fluxes and the Coupling with CO2 and CH4 Fluxes http://sites.agu.org/fallmeeting/scientific-program/session-search/133 Convener(s): Jim Tang ([email protected]), Peter Groffman ([email protected]), Meredith Hastings ([email protected]), Cheryl Palm ([email protected]) Description: Nitrous oxide (N2O) is a powerful greenhouse gas but its global emissions from natural ecosystems and agroecosystems are uncertain. N2O is a product of both nitrification and denitrification processes in soil and largely controlled by nitrogen availability, temperature, moisture, redox potential, pH, and other conditions. There is an emergent need to advance our ability to measure and model N2O fluxes and the coupling with CO2 and CH4 fluxes. This session aims to bring together ecologists, biogeochemists and biometeorologists who use recently developed technologies to measure and model N2O fluxes from various ecosystems based on eddy-covariance and chamber-based methods and simulation models Abstracts are due August 4th.

Biological events may have different ecosystem consequences than other disturbances; for example, insect infestations typically are not stand replacing and the understory and soil may be left relatively undisturbed, unlike most fire and harvesting events. Climate change is expected to increase the frequency, intensity and scale of biological disturbances in the future. We encourage measurements or modeling submissions that focus on process-level understanding on the consequences of and recovery from biological disturbance at different scales of biological organization from organism to ecosystem to region. Submission Deadline: August 4, 2011 AGU Meeting website: sites.agu.org/fallmeeting/ sites.agu.org/fallmeeting/scientific-program/session-search/102 Conveners: David Reed ([email protected]) Paul Stoy ([email protected]) Please feel free to distribute this message to colleagues and collaborators that may be interested in this AGU session. Please do not hesitate to contact us if you have any questions about the session and please remember that the abstract deadline is earlier this year. Thank you, Paul Stoy & David Reed
