The sea-ice cover around Antarctica has experienced a slight expansion in area over the
past decades,. This small overall increase is the sum of much larger opposing trends in
different sectors that have been proposed to result from changes in atmospheric temperature

However, climate models have failed to reproduce the overall increase in sea ice. Here we
present a data set of satellite-tracked sea-ice motion for the period of 1992–2010 that …
