Never so much sea ice at Antarctica in the last 30 years
In light of global warming, it seems paradoxical that the sea ice cover of the Southern Ocean has covered a larger area in the past month than in the last decades. Only in the mid-70s was observed a similar expansion.
The means were 19.48 million in September 2013 square kilometers, an area once covered more than 50 times larger than Germany with sea ice. The absolute maximum of 19.65 million square kilometers was reached on 18 of September. Although this maximum in the ice-covered surface can not be equated with a maximum of the total volume or mass, suggest that sea ice physicist Marcel Nicolaus and Stefan Hendricks from the Alfred Wegener Institute (AWI) “This winter there is in Antarctica as much ice as long gone, if it has ever been since the beginning of the regular satellite observations ever so much sea ice.”
To be able to make such statements in certain future, the researchers of the Alfred Wegener Institute is currently also the thickness of sea ice in the Antarctic work together with colleagues from different institutions that they can derive from satellite observations. In the Arctic, it has recently become possible, although there are significant differences between Arctic and Antarctic. The snow is thick, inhomogeneous and does not melt completely in summer. In addition, sea ice is formed at the top, a phenomenon that is encountered less frequently in the Arctic. Then there can also be calculated from the thickness and extent of sea ice volume in the future.
