Polaris Foreland
Hall Land is a peninsula in far northwestern Greenland. It is a part of the Northeast Greenland National Park. Hall Land is one of the coldest places in Greenland. History Hall Land was named after Charles Francis Hall, leader of the 1871 Polaris expedition. The last live caribou reported from Northern Greenland were seen in Hall Land in 1922. They were most likely Peary caribou that had strayed across the channel from Ellesmere Island.Morten Meldgaard, (1986) ''The Greenland Caribou - Zoogeography, Taxonomy, and Population Dynamics'', p. 44 Geography Hall Land is located to the northeast of Daugaard-Jensen Land and the southwest of Nyeboe Land. It is surrounded to the north by the Robeson Channel of the Nares Strait and to the east by the Newman Bay. Hall Basin, the Petermann Fjord and the Petermann Glacier mark the western limits of Hall Land. To the south and southeast the peninsula is attached to the mainland and its ice cap.

Robeson Channel
Robeson Channel () is a body of water lying between Greenland and Canada's northernmost island, Ellesmere Island. It is the most northerly part of Nares Strait, linking Hall Basin to the south with the Arctic Ocean to the north. The Newman Fjord in Greenland has its mouth in the Robeson Channel. It is about in length and between wide. Alert, the world's most northerly permanently inhabited settlement, lies nearby. It was named during the 1871 Polaris Expedition, for American George Robeson, Secretary of the Navy in the Ulysses S. Grant Ulysses S. Grant (born Hiram Ulysses Grant ; April 27, 1822July 23, 1885) was an American military officer and politician who served as the 18th president of the United States from 1869 to 1877.

Operational Navigation Chart A-5, 3rd Edition
An operational definition specifies concrete, replicable procedures designed to represent a construct. In the words of American psychologist S.S. Stevens (1935), "An operation is the performance which we execute in order to make known a concept." For example, an operational definition of "fear" (the construct) often includes measurable physiologic responses that occur in response to a perceived threat. Thus, "fear" might be operationally defined as specified changes in heart rate, galvanic skin response, pupil dilation, and blood pressure. Overview An operational definition is designed to model or represent a concept or theoretical definition, also known as a construct. Scientists should describe the operations (procedures, actions, or processes) that define the concept with enough specificity such that other investigators can replicate their research. Operational definitions are also used to define system states in terms of a specific, publicly accessible process of preparation ...

Haug Range
The Haug Range ( da, Hauge Bjerge) is a mountain range in far northwestern Greenland. Administratively this range is part of Avannaata municipality. The range is located in Hall Land, one of the coldest places in Greenland. This mountain chain was named after Ivar Haug, who compiled the first Gazetteer of Greenland. The area of the range is characterized by Tundra climate. Geography The Haug Range is an up to almost 1,100 m high little glaciated mountain range in Hall Land. It runs roughly from east to west across the peninsula, from the shores of the Nares Strait to the shores of the Newman Bay, separating the unglaciated Polaris Foreland in the north from the southern part of Hall Land. high Kayser Mountain, the highest elevation of the range, is located at its northeastern end. The area of the Haug Range is uninhabited. Google Earth Pentamerus fossils dating back to the Lower Silurian have been found in this mountain range. They belong to the Hauge Bjerge Formation. Se ...

Unglaciated
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Cap
In glaciology, an ice cap is a mass of ice that covers less than of land area (usually covering a highland area). Larger ice masses covering more than are termed ice sheets. Description Ice caps are not constrained by topographical features (i.e., they will lie over the top of mountains). By contrast, ice masses of similar size that ''are'' constrained by topographical features are known as ice fields. The ''dome'' of an ice cap is usually centred on the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery. Ice caps have significant effects on the geomorphology of the area that they occupy. Plastic moulding, gouging and other glacial erosional features become present upon the glacier's retreat. Many lakes, such as the Great Lakes in North America, as well as numerous valleys have been formed by glacial action over hundreds of thousands of years. On Earth, there are about of total ice mass.

Petermann Glacier
Petermann Glacier ( da, Petermann Gletsjer) is a large glacier located in North-West Greenland to the east of Nares Strait. It connects the Greenland ice sheet to the Arctic Ocean at 81°10' north latitude, near Hans Island. The glacier and its fjord are named after German cartographer August Heinrich Petermann. Geography The tidewater glacier consists of a long and wide floating ice tongue whose thickness changes from about at its grounding line to about at its front. Rough mass balance estimates using these scales suggest that about 80% of its mass is lost as basal meltwater, yet little oceanographic data are available to connect Petermann Glacier to its fjord and adjacent Nares Strait. Even the sill depth and location is largely unknown as modern soundings of the fjord, with its mouth located between Cape Morton and Cape Tyson, are still lacking. Petermann Glacier marks the western limit of Hall Land and the eastern of Daugaard-Jensen Land. The Petermann Peninsula flanks i ...

Petermann Fjord
Petermann Fjord is a fjord in northwestern Greenland. Administratively it marks the boundary between the Avannaata municipality and the Northeast Greenland National Park. The fjord and its glacier are named after German cartographer August Heinrich Petermann. Knud Rasmussen described the fjord entrance in the following terms: Geography Petermann Fjord stretches roughly from southeast to northwest for about 110 km. Its mouth opens in the Kennedy Channel and Hall Basin area, between Cape Lucie Marie, located east of Cape Morton, and Cape Tyson in the north, near Offley Island. It is a long and broad fjord lined with precipitous cliffs topped by glaciated plateaux. The Petermann Glacier, the longest glacier in Greenland, discharges into the fjord from the Greenland Ice Sheet, located further 80 km inland.''Prostar Sailing Directions 2005 Greenland and Iceland Enroute,'' p. 93 This fjord is located northeast of Daugaard-Jensen Land, between the Petermann Peninsula and Hall Lan ...

Nyeboe Land
Nyeboe Land ( da, Nyeboes Land) is a peninsula in far northwestern Greenland. It is a part of the Northeast Greenland National Park. History Nyeboe Land was named after engineer Marius Nyeboe (1867–1946), chairman of the committee of Knud Rasmussen's Fifth Thule Expedition. Geography Nyeboe Land is located to the northeast of Hall Land in the west, and southwest of Hendrik Island and west of Warming Land and the Steensby Glacier in the east. It is bounded to the north by the Lincoln Sea and to the east by Saint George Fjord. Newman Fjord (Newman Bay) marks the western limit of Nyeboe Land. To the south and southeast the peninsula is attached to the mainland and its ice cap. The Dreyer Firn is located in the southwest, near the Saint George Fjord's shore. There are three small bays in the northern shore, Repulse Harbour, Hand Bay and Frankfield Bay, from west to east.
