Session Proposal: Atmospheric Exchange of Aerosol and Gases Across the Air-Sea Interface (AGU25)

B018
Atmospheric Exchange of Aerosol and Gases Across the Air-Sea Interface

Session ID#: 251484

Session Description:
Aerosol and gas exchange across the air-sea interface integrates terrestrial, atmospheric, and marine processes within the Earth system. These interactions play a key role in modulating global carbon and nitrogen cycles, with flux variations significantly impacting biogeochemistry, climate, and society across diverse spatiotemporal scales.  Anthropogenic activities and climate change are altering these fluxes rapidly, underscoring the need for a comprehensive, coupled understanding of elemental cycles within the Earth System. Topics of interest include, but not limited to:  (1) Physical and chemical processes governing aerosol deposition and gas transfer across the sea surface;  (2) Nutrient and contaminant exchange and their impacts on marine ecosystems;  (3) Marine-derived emissions and feedbacks on regional and global climate, atmospheric chemistry, and cloud formation;  (4) Past and future changes to aerosol and gas fluxes and impacts on global biogeochemical cycles or climate regulation;  (5) Innovative observational methods, including autonomous platforms, remote sensing advancements, and modeling frameworks
