HE14A:
Dynamics of the Arctic Ocean and Sea Ice System in a Changing Climate III Posters
Session ID#: 7526
Session Description:
Major sea ice loss and Arctic air temperatures rising faster than the global mean are precursors of significant change that the Arctic Ocean is already beginning to experience. The retreat of sea ice greatly affects the Arctic system, allowing the direct exchange of heat, momentum and fresh water between ocean and atmosphere with implications for the ecosystem as well. Recently, novel and innovative year-round observational programs provide insight on this transition, however a correct interpretation of the changes inevitably requires an improved understanding of the actual processes at play. In the context of a changing Arctic, this session invites observational and modeling studies describing and quantifying dynamical processes, feedbacks and the role of fluxes across the air-ice-ocean interface. Particular attention will be paid to topics such as momentum transfer into the ocean, the transfer of energy across scales, connections between the surface and the deep ocean (e.g. internal waves and mixing), and links to changes in stratification and large-scale circulation. Submissions on both physical and multi-disciplinary aspects are welcome.
