Gåsøyane is located in the Svalbard archipelago in the inner part of Isfjorden and consists of two small, partially vegetated islands with a few freshwater ponds and cliffs suitable for nesting seabirds. The Site is among the most important Spitsbergen localities for the nesting common eider Somateria mollissima and the barnacle goose Branta leucopsis, with over 1% of populations supported by the Site. In the past, and sporadically still today, the Site has been used for the collection of eider eggs and down. Polar bears regularly visit the Site. Some research and biodiversity monitoring have been conducted in the area, but due to its remoteness, the Site is rarely visited.
