The Dynamics of the Arctic Ocean
Gianluca Meneghello

The Arctic Ocean is one of the fastest changing and least understood oceans on the planet. It is also a crucial element of the climate system. Changes in the Arctic circulation, associated with changes in atmospheric forcing and in the extent and state of the ice cover, have far-reaching implications for the global ocean circulation and climate.

In this talk, I will combine observations with analytical and numerical models to uncover how the Arctic Ocean's dynamics differ substantially from that of other oceans. I will show how the interaction between sea ice and surface currents regulates the basin's large-scale circulation and controls the size of the world's largest oceanic reservoir of freshwater. I will further discuss how, at smaller scales, the interplay of sea ice and stratification explains the peculiarities of the Arctic Ocean’s turbulence and controls the transport of heat and other tracers. I will conclude by discussing future research directions on the implications of these findings for the evolution of the Arctic and its relationship with lower latitudes.

William Dewar is inviting you to a scheduled Zoom meeting.
