Arctic ice thickness 2010–13

ESA’s CryoSat satellite has built up a three-year record of sea-ice thickness in the Arctic. This key result, which is based on measurements taken between October 2010 and April 2013, has allowed scientists to calculate changes in the volume of ice. The results reveal that the volume of seasonal winter and summer sea ice has declined year on year during this period. Set to continue delivering these vital measurements until 2017, CryoSat is offering new evidence of polar change. These latest results were presented at ESA’s 2013 Living Planet Symposium in Edinburgh, Scotland.
