Gridded Arctic Marine Regions Codes at resolutions of 1, 3.125, 6.25, 12.5, 25, 50 & 75 km. The source data are shapefiles from the National Snow and Ice Data Center (NSIDC): A new regional mask for Arctic sea ice trends and climatologies (J. Scott Stewart and Walter N. Meier, NSIDC) (last accessed June 2024) Region Code Region Name 0 Undefined Region 1 Central Arctic 2 Beaufort Sea 3 Chukchi Sea 4 East Siberian Sea 5 Laptev Sea 6 Kara Sea 7 Barents Sea 8 East Greenland Sea 9 Baffin Bay & Labrador Sea 10 Gulf of St. Lawrence 11 Hudson Bay 12 Canadian Archipelago 13 Bering Sea 14 Sea of Okhotsk 15 Sea of Japan 16 Bohai Sea 17 Baltic Sea 18 Gulf of Alaska Data files contain resolution in meters in the filename (nsidc_arctic_region_mask_2021_ease2_{resolution_m}.nc). The file format is netCDF-4 and the datafile contains one variable (region_id). The coordinate reference system of the variables is defined by EPSG:6931 (WGS 84 / NSIDC EASE-Grid 2.0 North) and the bounds of the data set are supplied as xc and yc variables in the data file.
