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 Ha ...

Arctic
The Arctic ( or ) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia ( Murmansk, Siberia, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. Definition and etymology The word Arctic comes from the Greek word ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Morton
Cape Morton ( da, Kap Morton) is a headland in North Greenland in Avannaata municipality. The cape is named after Arctic explorer William Morton, who surveyed the Nares Strait area together with Hans Hendrik in June 1854 during the Second Grinnell Expedition. Fossils dating back to the Homerian have been found in the area of the cape. They belong to the Kap Morton Formation of the Peary Land Group. Geography Cape Morton is located west of Cape Lucie Marie, off the mouth of the Petermann Fjord opposite Cape Tyson at the northern end of the Petermann Peninsula. Mushroom-shaped Joe Island lies 3.2 km from the shore west-north-west of the cape. Together with Cape Baird on the eastern coast of Ellesmere Island this cape marks the northern limit of the Kennedy Channel and the entrance of the Hall Basin, both part of the Nares Strait.''Prostar Sailing Directions 2005 Greenland and Iceland Enroute'', p. 93 See also *List of fossiliferous stratigraphic units in Greenland ...

Glacial Canyon, Northern Greenland-2
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period ...

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 ...

Hall Land
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.

Daugaard-Jensen Land
Daugaard-Jensen Land, ( da, Daugård-Jensen Land), is a peninsula in northwestern Greenland. It is a part of the Avannaata municipality. Daugaard-Jensen Land was named in honour of Jens Daugaard-Jensen (1871–1938), who was Inspector of Greenland between 1900 and 1912. Geography Daugaard-Jensen Land is located between Washington Land and the Petermann Glacier.

Greenland Ice Sheet
The Greenland ice sheet ( da, Grønlands indlandsis, kl, Sermersuaq) is a vast body of ice covering , roughly near 80% of the surface of Greenland. It is sometimes referred to as an ice cap, or under the term ''inland ice'', or its Danish equivalent, ''indlandsis''. An acronym, GIS, is frequently used in the scientific literature. It is the second largest ice body in the world, after the Antarctic ice sheet. The ice sheet is almost long in a north–south direction, and its greatest width is at a latitude of 77°N, near its northern margin. The average thickness is about and over at its thickest point. In addition to the large ice sheet, smaller ice caps (such as Maniitsoq and Flade Isblink) as well as glaciers, cover between around the periphery. The Greenland ice sheet is adversely affected by climate change. It is more vulnerable to climate change than the Antarctic ice sheet because of its position in the Arctic, where it is subject to the regional amplificatio ...

Offley Island
Offley is a civil parish in the English county of Hertfordshire, between Hitchin and Luton. The main village is Great Offley, and the parish also contains the nearby hamlets of Little Offley and The Flints. In the south-west of the parish, near Luton, there are the hamlets of Cockernhoe, Mangrove Green and Tea Green, and also the Putteridge Bury estate; these have LU2 postcodes and 01582 telephone numbers.

Cape Tyson
A cape is a clothing accessory or a sleeveless outer garment which drapes the wearer's back, arms, and chest, and connects at the neck. History Capes were common in medieval Europe, especially when combined with a Hood (headgear), hood in the Chaperon (headgear), chaperon. They have had periodic returns to fashion - for example, in nineteenth-century Europe. Roman Catholic clergy wear a type of cape known as a ferraiolo, which is worn for formal events outside a ritualistic context. The cope is a liturgical vestment in the form of a cape. Capes are often highly decorated with elaborate embroidery. Capes remain in regular use as rainwear in various military units and police forces, in France for example. A gas cape was a voluminous military garment designed to give rain protection to someone wearing the bulky gas masks used in twentieth-century wars. Rich noblemen and elite warriors of the Aztec Empire would wear a tilmàtli; a Mesoamerican cloak/cape used as a symbol of thei ...

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 flan ...
