Arctic sea ice melt during the summer of 2012. Summer 2012 saw the sea ice in the Arctic Ocean drop below the previous all-time record low set in 2007. This animation shows the ice extent changing over time using sea ice concentration data from the DMSP SSMI/S satellite sensor. The dark area represents the daily average (median) sea ice extent over the 1979-2000 time period. Layered over top of that are the daily satellite measurements from 1st January to 14th September 2012. A rapid melt begins in July, after which the ice extent falls far below the historical average.
