[2] The area was later visited by the ill-fated 1906–08 Denmark Expedition (Danmark Ekspeditionen) which named a few landmarks, such as the narrow Syttendemajfjorden in the north.

It was named after Danish zoologist Adolf Severin Jensen (1866 - 1953), professor at the University of Copenhagen, who had carried out extensive research on the fisheries of West Greenland, and who was a member of the committee of the 1931–34 Three-year Expedition.

[2] Adolf S. Jensen Land is bounded in the west by the Soranerbraen Glacier —beyond which lies Rechnitzer Land, in the north by the Fangersund of the Inderbredningen and the Trangsund of the Dove Bay, in the east by the Storebaelt that opens into the Greenland Sea, and in the south by the Bessel Fjord.

[2] Cape Karl Ritter is the peninsula's easternmost point and the Hawkins Vandfald waterfall is located in the southeastern part.

There is an ice cap in the SW.[1] Adolf S. Jensen Land is hilly, except for a small area in the southeast, and its coastline is very indented.
