Sea ice coverage in inner Kongsfjorden, Svalbard, 2003-2019, version 1.0
Monthly values for sea ice extent in the inner part of Kongsfjorden, Svalbard 2003-2019, as percentages of the total surface area during February-June each year. The data file has six columns: a) the year the data connects to, and b)-f) the numbers for maximum fast ice coverage (in percent from the...
