Arctic sea ice thickness from CryoSat data acquired between 9 November and 8 December 2014. Bright white shows the sea ice extent at the start of the period, while light grey is the extent at the end. Coloured dots show ice thickness up to 3.5 m (pink). Scientists are working to deliver operational capabilities from the CryoSat mission, so that the measurements can be used for routine assessments in climate science and for services affected by Arctic sea ice, such as shipping.
