Session Proposal: Aerosols and Chemistry in Aquatic Environments (AGU25)

A020
Aerosols and Chemistry in Aquatic Environments

Session ID#: 249515

Session Description:
Aquatic environments, covering over 70% of the planet, are major sources of atmospheric aerosols and play a critical role in controlling atmospheric composition. Sea and lake spray aerosols impact the radiative properties, chemistry, and biodiversity of the atmosphere. Various particle types serve as cloud condensation and ice nuclei, provide media for heterogeneous chemistry, and transfer pollutants, microorganisms, and biogenic material to the atmosphere, thereby affecting human health and ecosystems. Areas of active marine boundary layer research include air/sea exchange, chemistry, and microphysics impacting reactive halogens, sulfur, and nitrogen. These processes impact global oxidation capacity, cloud albedo, and ozone in the troposphere and stratosphere. Recent advances in high-resolution observations, modeling, and experimental methods allow new insights into these complex and interconnected systems. We invite new studies that enhance understanding of aquatic aerosols, air/sea exchange and chemical processes impacting the marine boundary layer, spanning molecular to global scales.
