Spatial differences in the distribution of leads in the ice cover in the Atlantic sector of the Arctic basin
We analyzed data on the spatial distribution (density) of large breaks (gaps) in the drifting sea ice cover in the Western Arctic for the period from October 2005 to September 2017, obtained through decoding of lowresolution images from the NOAA satellites. The specific length of gaps, which is the...
