The Arctic Shelf Seas are currently experiencing rapid environmental change due to natural and anthropogenic factors. Therefore, studying the processes impacting gas and aerosol exchange across the air-sea interface is critical for the prediction of climate change impacts and the understanding of marine ecosystem dynamics. However, this is challenging due to limited field observation on the spatial and temporal scales associated with logistical difficulties. Fortunately, over the past decade major field campaigns, breakthroughs in autonomous platforms and sensors, and innovations in numerical modeling have significantly advanced our understanding of the processes and rates of air-sea gas exchange, particularly for carbon dioxide. This session invites theoretical, experimental, observational, and model studies as well as technological advances for the investigation of the biogeochemical processes and air-sea gas and aerosol exchange in the Arctic shelves at different spatial and temporal scales.
