HE34B:
The Role of Small-Scale Processes in the Dynamics of the Changing Arctic Ocean III Posters


Session ID#: 27542

Session Description:
The Arctic Ocean and sea ice are undergoing marked changes under continued global warming. Observations indicate that Arctic Ocean circulation, stratification, freshwater, and heat content have been changing in response to atmospheric winds, reduced sea ice cover, increased solar warming, changing freshwater sources, and advection of heat from the Pacific and Atlantic oceans. Ocean heat and salt transport by flows at all scales are contributing to sea-ice losses, the distribution and storage of freshwater, and associated feedbacks across the Arctic. Basin-scale changes are profoundly affected by small-scale ocean processes such as mesoscale and submesoscale turbulence, wave breaking and vertical mixing. This session invites submissions that explore the influence of small-scale processes on sea ice and large-scale Arctic Ocean dynamics and thermodynamics. We welcome theoretical, observational, and modeling studies on eddies, waves, mixing and stirring, and their impact on basin-scale Arctic variability and change.
