Mørkefjord, meaning in Danish "The dark fjord,"[2] is a fjord in King Frederick VIII Land, northeastern Greenland.
Mørkefjord was named by the 1906-1908 Denmark expedition, which established a second weather station at Mørkefjord, in order to compare meteorological observations data with those taken at Danmarkshavn .[3] It had also been known as Vigfusdalfjord.[4]
The 1938–1939 Mørkefjord expedition was named after it. They built their base hut and repaired their ship "Gamma" at a place by the fjord's shores.
There are remains of Inuit sites at the mouth of the fjord.[5]
This fjord is located east of Danmarkshavn in Daniel Bruun Land. There are two parallel fjords close to it, Hellefjord to the south, and Sælsøen, a lake with a fjord structure, to the north.[6] It runs from east to west for about 30 km. There is a small branch on its southern shore. Kalvenø island is located off its mouth in northern Dove Bay.[1]
