Climate

Main article: Climate of Greenland

Jameson Land experiences a tundra climate (Köppen: ET); with short, cool summers and long, frigid winters.^[1] Temperature & humidity data within the weatherbox below was recorded from the Nerlerit Inaat Airport (2002-2020) and precipitation was sourced from Uunarteq (1958-1980).

Geology

Jameson Land mainly consists of a tilted peneplain of Jurassic sandstone, highest in the east. In the northern end there are also rocks of Triassic age.^[4] Two formations are predominant in Jameson Land: the Triassic Fleming Fjord Formation and the Jurassic Kap Stewart Formation. Triassic fossils of the Fleming Fjord Formation in Jameson Land include: the dipnoi Ceratodus,^[5] prosauropod and theropod dinosaurs bones and tracks, sauropod tracks,^[6] phytosaurs, temnospondyls, and sharks.^[7]
