The maps above show a spatial view of the sea ice concentrations for the whole of the Arctic, with
the average ice edge for the particular month indicated by a pink line.
The average ice edge is shown in black.

Over the current century, the model projects that the
average albedo for the entire
ice sheet will fall by as much as 8 percent, and by as much 10 percent on the western
edge, where the
ice is darkest today.
Air temperatures near the Antarctic sea
ice edge were near
average.
Average distance from land and pack
ice edge for live polar bears swimming in open water in 2004 (n = 10) were 8.3 ± 3.0 and 177.4 ± 5.1 km, respectively.
Note that the datasets show different quantities; in the sea
ice zone the GISTEMP, M10 and CHAPMAN data represent air temperature (though CHAPMAN air temperatures are inferred from SST input data); north of the sea
ice edge the M10 and CHAPMAN data represent air temperature while GISTEMP represents SST; MSU represents tropospheric -
average temperatures everywhere.
In September 2017, while large areas of the
ice edge were further south than
average, the
ice edge was actually further north than
average in the Bellingshausen Sea, and in two small regions lying roughly due south of South Africa and Australia respectively (Figure 7).
Very warm conditions continued in the Kara and Barents seas, with temperatures as much as 3 to 6 degrees Celsius (5 to 11 degrees Fahrenheit) above
average, consistent with the retreat of the
ice cover to the northern
edge of the Svalbard, Franz Josef, and New Siberian Islands.
