Recent Antarctic sea ice trends in the context of Southern Ocean surface climate variations since 1950
This study compares the distribution of surface climate trends over the Southern Ocean in austral summer between 1979-2011 and 1950-1978, using a wide variety of data sets including uninterpolated gridded marine archives, land station data, reanalysis, and satellite products. Apart from the Antarcti...
