Farquhar Glacier (Danish : Farquhar Gletscher), is a glacier in northwestern Greenland. [2] Administratively it belongs to the Avannaata municipality.

Danish language North Germanic language spoken in Denmark

Danish is a North Germanic language spoken by around six million people, principally in Denmark and in the region of Southern Schleswig in northern Germany, where it has minority language status. Also, minor Danish-speaking communities are found in Norway, Sweden, Spain, the United States, Canada, Brazil, and Argentina. Due to immigration and language shift in urban areas, around 15–20% of the population of Greenland speak Danish as their first language.

Glacier Persistent body of ice that is moving under its own weight

A glacier is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.

Greenland autonomous country within the Kingdom of Denmark

Greenland is an autonomous constituent country of the Kingdom of Denmark between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Though physiographically a part of the continent of North America, Greenland has been politically and culturally associated with Europe for more than a millennium. The majority of its residents are Inuit, whose ancestors began migrating from the Canadian mainland in the 13th century, gradually settling across the island.

This glacier was named by Robert Peary after Commodore Farquhar (1840 – 1907), Chief of the Bureau of Yards and Docks. [3]

Robert Peary explorer from the United States

Rear Admiral Robert Edwin Peary Sr. was an American explorer and United States Navy officer who made several expeditions to the Arctic in the late 19th and early 20th centuries. He is best known for claiming to have reached the geographic North Pole with his expedition on April 6, 1909.

Norman von Heldreich Farquhar United States Navy admiral

Rear Admiral Norman von Heldreich Farquhar was an officer in the United States Navy during the American Civil War. He is best known for commanding a naval squadron which was wrecked with three German warships at Apia, Samoa in 1889.

Bureau of Yards and Docks

The Bureau of Yards and Docks was the branch of the United States Navy responsible from 1842 to 1966 for building and maintaining navy yards, drydocks, and other facilities relating to ship construction, maintenance, and repair.

Geography

The Farquhar Glacier discharges from the Greenland Ice Sheet into the northern side of the head of the Inglefield Fjord just northeast of Josephine Peary Island. Its terminus lies between two nunataks: Mount Lee in the east separates it from the Tracy Glacier to the southeast and Mount Field, a larger nunatak to the west, separates it from the Melville Glacier to the northwest. [2]

Nunatak Exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier

A nunatak is an exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons.

Tracy Glacier (Greenland)

Tracy Glacier, is a glacier in northwestern Greenland. Administratively it belongs to the Avannaata municipality.

Formerly the roughly NE/SW flowing Farquhar Glacier joined with the east/west flowing Tracy Glacier at their terminus. [1] However, these two glaciers lost contact after the terminus disintegrated in 2002. [4]

Glacier terminus

A glacier terminus, toe, or snout, is the end of a glacier at any given point in time. Although glaciers seem motionless to the observer, in reality glaciers are in endless motion and the glacier terminus is always either advancing or retreating. The location of the terminus is often directly related to glacier mass balance, which is based on the amount of snowfall which occurs in the accumulation zone of a glacier, as compared to the amount that is melted in the ablation zone. The position of a glacier terminus is also impacted by localized or regional temperature change over time.
