B23I:
The Bio-atmospheric N Cycle: N Emissions, Transformations, Deposition, and Terrestrial and Aquatic Ecosystem Impacts II

Submit an Abstract to this Session



Session ID#: 31815

Session Description:
Biogenic and anthropogenic emissions of reactive nitrogen (Nr) are transported, chemically transformed, and deposited on land and waters, altering structure and function of ecosystems and degrading environmental quality. Estimating atmospheric N 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, impacts on ecosystems, carbon uptake, nitrogen export, biodiversity, human health, and policy implications and responses.
