AI43B:
Processes Affecting Air-Sea Exchange and the Biogeochemistry of the Upper Ocean IV eLightning

Session ID#: 93606

Session Description:
Gas, aerosol, and heat exchange processes across the air-sea interface impact global biogeochemical cycles, marine ecosystem dynamics, and atmospheric chemistry. Understanding these exchange processes is therefore critical for the prediction of climate change. Atmospheric deposition of micro- and macro-nutrients, organic matter, and pollutants influence biogeochemical cycling, primary productivity, and biological community composition in the ocean. Emissions of gases and aerosol particles from the sea surface to the atmosphere affect the number and composition of cloud condensation nuclei and ice nucleating particles with important consequences for understanding clouds and climate. Upper-ocean processes, including the sea surface microlayer and phytoplankton and microbial compositions, are both affected by and influence these exchange processes. The upper ocean with its high and variable incident radiation, turbulence, and physical, chemical, and biological horizontal and vertical gradients must therefore be considered when estimating exchange rates of particles, heat and gases. 

Over the past decade, major field campaigns in chronically under-observed regions, breakthroughs in autonomous platforms and sensors, and innovations in numerical modeling and data analysis techniques have significantly advanced our understanding of the processes and rates of air-sea gas exchange, particularly for carbon dioxide. These advances are helping to improve regional and global model estimates of carbon budgets, and therefore, baseline information for the UN Decade of Ocean Science for Sustainable Development. This session invites theoretical, experimental, observational and model studies as well as technological advances for the investigation of upper ocean biogeochemical influences on and consequences of air-sea exchange processes.
