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 water within the sea ice cover of the Southern Ocean, which overlies an area of elevated topography called Maud Rise (66S, 3E) located in the eastern sector of the Weddell Sea (Fig. SB6.1a). It is termed a Weddell polynya if it grows and migrates we...

The Maud Rise polynya is a persistent area of open water within the sea ice cover of the Southern Ocean, which overlies an area of elevated topography called Maud Rise (66S, 3E) located in the eastern sector of the Weddell Sea (Fig. SB6.1a). It is termed a Weddell polynya if it grows and migrates westward into the central Weddell Sea. This larger sized polynya was first observed in satellite data in 1974 and recurred for each of the two subsequent austral winters (Zwally and Gloersen 1977; Carsey 1980).
