The Arctic Basin coupled system is changing rapidly. Many of these changes and processes are interdependent. For example, 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 ecological processes. In addition, Arctic sea ice and snow cover change could be altering clouds. In this session we welcome field, laboratory, remote sensing, and modeling studies that examine all aspects of the changing Arctic coupled system, especially including processes that cut across the atmosphere, sea ice, snow, ocean, biogeochemistry, and ecosystem. Submissions are encouraged that incorporate cross-disciplinary research, examine inter-seasonal linkages, conduct observation-model synthesis, and/or bridge the spatial and temporal scales between in situ observations and large scale remote-sensing and modeling. Contributions from recent Arctic field campaigns like ARCSIX, MOSAiC, and CONTRASTS are particularly relevant.
