Marginal Ice zone. Some definitions: Wadhams (1986) : "that part of the ice cover which is close enough to the open ocean boundary to be affected by its presence".

Marginal Ice zone
The variability of ice concentration outline areas where marginal ice zone exists
Standard deviation of sea ice concentration. 1979-2009
There appears to be a shift in mean Arctic Ocean ice concentration after 2007. Reprocessing of 2010-2013 data will reveal more…
Average sea ice concentration in March and September, for ice concentration greater than 15% - North of 80N.

Oden, Summer 2012.
White is Ice, colors are No-Ice
IC varying between 0.3 and 0.8
-> Skin temperatures reflect alternately water, ice and mixing temperatures.
IC correlated with skin temperatures -> water is colder than ice surface.
The air temperature is the coldest of 5 ship thermometers. However, the measurement must be read with causion as ship heating may influence the measure…
3-hour sampling of coincident measurements of ship air temperatures (blue), TIR skin temperatures (green) and photo determined ice concentrations.
