Jameson Land is a peninsula in eastern Greenland. The peninsula is located north of Scoresby Sound, opposite of King Christian IX Land. Administratively it falls within Sermersooq municipality.

Geography

Jameson Land is bounded to the south by Scoresby Sound (the world's largest fjord), to the northwest by the Stauning Alps, to the north by Scoresby Land, to the northeast by the Fleming Fjord and the Nathorst Fjord of the Greenland Sea, and to the east by Carlsberg Fjord, the smaller Liverpool Land peninsula branching off, and Hurry Inlet. Its northeastern end is Cape Biot.[1]

Climate

Main article: Climate of Greenland

Jameson Land experiences a tundra climate (Köppen: ET); with short, cool summers and long, frigid winters.[2] Temperature & humidity data within the weatherbox below was recorded from the Nerlerit Inaat Airport (2002-2020) and precipitation was sourced from Uunarteq (1958-1980).

Ecology

The peninsula's flora includes alpine foxtail, arctic bell-heather, arctic willow, Bigelow's sedge, bog blueberries, various types of cottongrass, dwarf birch, Kentucky bluegrass, moss campion, mountain avens, varioues sedges, slim-stem small reed grass, wideleaf polargrass and the fungus Stereocaulon alpinum.[3]

The peninsula is home to muskoxen, who sustain themselves off mainly willows during summer and various graminoids during winter.[3]

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]
