Ice Extent in Norwegian Fjords from 2000 to 2019

Through analysis of MODIS images, approximate ice extent in fjords along the coast of Norway from 2000 – 2019 is determined. Regions are compared to reveal increases and decreases between regions that often do not align. The length of the ice season and seasonal trends, i.e. areas where ice breaks up throughout the winter vs. those where ice cover is continuous, are apparent. Maximum ice extent is compared to values for freezing degree days, sum of daily new snow, sum of rainfall/snowmelt, and freezing degree days five days after a rain event to show correlations dependent on regions. When three fjords located within 100 km of each other are examined more closely, correlations are not consistent, the possible causes are considered.
