The central Arctic coupled environmental system is changing rapidly, with dramatic potential implications for climate, weather, ecosystems, and society. Thinner and less extensive sea ice can impact the flow of heat, the exchange of gases, seasonal melt and freeze of ice, ice dynamics, light available for biological productivity, and many other related physical, biogeochemical, and ecosystem processes. Importantly, many of these changes and processes are interdependent. In this session we welcome field, laboratory, remote sensing, and modeling studies that examine all aspects of the changing central Arctic coupled system, especially including processes that cut across the atmosphere, sea ice, snow, and ocean. Submissions are encouraged that incorporate cross-disciplinary research topics, interseasonal linkages, and/or combined observing-modeling syntheses. Contributions from recent central Arctic field campaigns like MOSAiC are particularly relevant.
