  • Time period: 1997/98 - 2012/13
  • Location: Isfjorden / Kongsfjorden
  • The following index per month (Nov-May):

Creating Mask
  • Layer> New Shapefile Layer
  • Toggle Edit > Add Feature
  • Draw Polygon, double click on last point to end
  • Rasterize Polygon into subset raster size (rename a copy of the test output to "mask")
  • Raster Calculator: ("isfjordenmask@1" = 2 ) * "isfjordenmask@1"
  • Now "0" where area, "2" where mask
