NOAA Releases Sea Ice Visualization for 2012

September 18, 2012

If this is being released, one would think they are pretty close to announcing the minimum.

Description:

The sea ice in the Arctic Ocean dropped below the previous all-time record set in 2007. This year also marks the first time that there has been less than 4 million square kilometers (1.54 million square miles) of sea ice since satellite observations began in 1979.

This animation shows the 2012 time-series of ice extent using sea ice concentration data from the DMSP SSMI/S satellite sensor. The black 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 January 1 — September 14, 2012.

A rapid melt begins in July, whereby the 2012 ice extents fall far below the historical average. The National Snow and Ice Data Center (www.nsidc.org) will confirm the final minimum ice extent data and area once the melt stabilizes, usually in mid-September.

    Per the FB transcript I sent you yesterday, Julienne Stroeve tells me that the ice is still melting. Don’t know if she’s still up there in the arctic, but I can imagine CU and NSIDC will have lots of profound info in the weeks (days?) ahead.
