Return of the Maud Rise Polynya: climate litmus or sea ice anomaly? [in “State of the Climate in 2017”]
The Maud Rise polynya is a persistent area of open waterwithin the sea ice cover of the Southern Ocean, which overliesan area of elevated topography called Maud Rise (66°S, 3°E)located in the eastern sector of the Weddell Sea (Fig. SB6.1a).It is termed a “Weddell polynya” if it grows and migrates we...
