26 October 2007
| The animation shows changing sea ice extent and concentration from 12 March to 24 September 2007. These weekly and bi-weekly Arctic charts are based on the analysis of observations from a diverse number of satellite missions including ESA's Envisat, CSA's RADARSAT-1, NASA's QuikSCAT, DMSP, and NOAA.
