There are several links I’ve used in class. The 31 day animation I’ve used is https://www.natice.noaa.gov/ims/loop/ak-1mo-loop.html. This shows the past 31 days of change in sea ice margins. The still pictures I’ve used can be found at https://arctic.atmos.uiuc.edu/cryosphere/NEWIMAGES/arctic.seaice.color.000.png and https://arctic.atmos.uiuc.edu/cryosphere/NEWIMAGES/arctic.seaice.color.000.png. Both of these offer great visuals of current sea ice margins in Alaska.
