Exploring the role of the “Ice-Ocean governor” and mesoscale eddies in the equilibration of the Beaufort Gyre: lessons from observations
Observations of Ekman pumping, sea surface height anomaly, and isohaline depth anomaly over the Beaufort Gyre are used to explore the relative importance and role of (i) feedbacks between ice and ocean currents, dubbed the “Ice-Ocean governor” and (ii) mesoscale eddy processes in the equilibration o...
