CT14A:
Atmospheric Deposition and Ocean Biogeochemistry II Posters


Session ID#: 9243

Session Description:
Atmospheric deposition of marine, lithogenic and anthropogenic aerosols is an important transport pathway for nutrients and contaminants to the surface ocean. Constraining local, regional and global atmospheric deposition flux estimates and the bioavailability of aerosol-derived elements and compounds is essential for furthering understanding of ocean biogeochemistry. This transport pathway acts as an important chemical bridge between the lithosphere and hydrosphere linking major biogeochemical cycles. Aerosol emission, transport and deposition processes are, in part, a function of global change related to changes in land coverage, anthropogenic emissions and climate. Hence the study of ocean responses will improve our ability to predict future impacts. The GEOTRACES international program includes objectives related to the atmospheric input of trace elements and isotopes to accomplish its goal. Other programs, such as SOLAS and CLIVAR, continue to make significant contributions as well. This session invites contributions from studies of atmospheric deposition in the marine environment, including observations of atmospheric deposition fluxes, aerosol composition, aerosol fractional solubility, the fate of aerosol-derived compounds and the biological and chemical response to deposition within the surface ocean. Contributions from global and regional scale field observations, laboratory studies and modeling efforts are welcomed.
