Dear colleagues, Please take note of a session at this fall's AGU meeting (Dec 13-17, 2010) entitled "The Bio-atmospheric N cycle: N emissions, transformations, deposition, and terrestrial and aquatic ecosystem impacts” (B46) (full description below). Note that abstracts are due to AGU by 2 September 2010 (http://www.agu.org/meetings/fm10/).
Please pass along to colleagues you think might be interested. -Emily B46: The Bio-atmospheric N cycle: N emissions, transformations, deposition, and terrestrial and aquatic ecosystem impacts Biogenic and anthropogenic emissions of reactive nitrogen (Nr) are transported and chemically transformed in the atmosphere and deposited on terrestrial and aquatic ecosystems, altering the structure and function of those systems and potentially degrading environmental quality. Estimating atmospheric N exchange, including emissions and deposition, and evaluating ecosystem responses require a diverse array of measurements and models that link processes at multiple scales. We seek presentations on physical, chemical, biological, and anthropogenic processes that drive local, regional and global nitrogen exchange, resultant impacts on ecosystem structure, function, carbon uptake, nitrogen export, biodiversity, human health, and the ultimate fate of deposited Nr, as well as policy implications and responses.
