Current measurements of the ESA ice thickness satellite CryoSat-2 have shown that the total mass of the Arctic sea ice was 36% smaller last autumn than during the same period from 2003 to 2008. This conclusion was reached by an international research team after comparing the CryoSat data of the past two years with measurements of a former NASA satellite and with the results of sea ice investigations of the Alfred Wegener Institute, Helmholtz Centre for Polar & Marine Research.
