Improved mapping of sea ice production in the Arctic Ocean using AMSR-E thin ice thickness algorithm
New and improved estimates of sea ice production in the Arctic Ocean are derived from AMSR-E satellite and atmospheric reanalysis data for the period 2002-2011, at a spatial resolution of 6.25 km and using a newly developed fast-ice mask. High ice production in the major coastal polynyas is well dem...

New and improved estimates of sea ice production in the Arctic Ocean are derived from AMSR-E satellite and atmospheric reanalysis data for the period 2002-2011, at a spatial resolution of 6.25 km and using a newly developed fast-ice mask. High ice production in the major coastal polynyas is well demonstrated. The total annual cumulative ice production in the major 10 polynya regions is about 118070km 3. The interannual variability of the ice production for each polynya is presented during 2002-2011. No obvious relationship is noted between the ice production and the recent drastic reduction in the preceding summer Arctic sea ice extent. Most polynya regions exhibit maximum ice production in autumn (October - November), before areas offshore have been covered with consolidated pack ice.
