Ice extent in sub-arctic fjords and coastal areas from 2001 to 2019 analyzed from MODIS imagery
Results examining variations in the ice extent along the Norwegian coastline based on the analysis of Moderate Resolution Imaging Spectroradiometer (MODIS) images from 2001 to 2019, February through May, are presented. A total of 386 fjords and coastal areas were outlined and grouped into ten region...
