Aage Bertelsen Glacier
Bertelsen Glacier () is a glacier in northern Greenland.Google Earth Administratively it belongs to the Northeast Greenland National Park. Between 2006 and 2010 there was an automatic weather station near the glacier. The glacier was mapped with accuracy by Lauge Koch during an aerial survey in May 1938. It had previously not been seen by Robert Peary during his 1902 exploration of the area that put the adjacent Moore Glacier in the map. The glacier was named in honour of Aage Bertelsen, who had taken part in the 1906–1908 Danmark Expedition. Geography The Bertelsen Glacier is one of the main glaciers in eastern Peary Land. It is a valley glacier, a branch of the larger, northwest-flowing Moore Glacier, joining it from the northeast. It is located in the area of the easternmost subranges of the Roosevelt Range, between the H. H. Benedict Range to the southwest and the Daly Range to the northeast.

Operational Navigation Chart
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, electrodermal activity, 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 ...

Lauge Koch
Lauge Koch (5 July 1892 – 5 June 1964) was a Danish geologist and Arctic explorer. Biography Lauge Koch was born in 1892 to Karl and Elisabeth Koch. His development as a scientist was greatly influenced by his father's second cousin Johan Peter Koch - a polar explorer, a member of several Greenland expeditions, including Ludvig Mylius-Erichsen's and Alfred Wegener's (in the latter's expedition (1912-1913) to cross Greenland, he led a sledging party). He received his higher education at the University of Copenhagen, where he began his studies in 1911, in 1920 he received a master's degree, and in 1929 a doctor of Philosophy, doctor's degree, having defended a dissertation on the topic "Stratigraphy of Greenland". General He was the renowned leader of 24 Denmark, Danish government expeditions to Greenland, and the central character in the ''Lauge Koch Controversy'', an international and intra-national conflict. Beginning in December 1935 a bitter conflict arose between Koch and el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Daly Range
The Daly Range or Daly Mountains () is a mountain range in Peary Land, Northern Greenland. Administratively this range is part of the Northeast Greenland National Park. It forms the eastern end of the northernmost mountain range on Earth.2002 American Alpine Journal, p.286 The area of the range is barren and uninhabited. History The mountain chain was named by Robert Peary after Judge Charles P. Daly, President of the American Geographical Society and member of the executive committee of the Peary Arctic Club in New York. In 1900 Peary saw the range from the coast and was the first to put it on the map. The Daly Range was further surveyed in 1907 by Johan Peter Koch, Aage Bertelsen and Tobias Gabrielsen, the northern team of the ill-fated Denmark expedition, when they reached their northernmost point, Cape Bridgman.

Roosevelt Range
The Roosevelt Range or Roosevelt Mountains () is a mountain range in Northern Greenland. Administratively this range is part of the Northeast Greenland National Park. Its highest peak is the highest point in Peary Land. Located about from the North Pole, the Roosevelt Range is the northernmost mountain range on Earth.2002 American Alpine Journal, p.286 History The mountain chain was named by Robert Peary after U.S. President Theodore Roosevelt, who would become one of the main backers of Peary's 1905 Arctic expedition. During the first half of the 20th century the range was quite unexplored, except for the mapping from the coast in 1907 of the Daly Range by Johan Peter Koch, Aage Bertelsen and Tobias Gabrielsen, the northern team of the ill-fated Denmark expedition, as well as aerial surveys and mapping begun by Lauge Koch in the 1920s. In 1953 a geological expedition crossed the range through the ''Polkorridoren'' pass from Frigg Fjord to Sands Fjord. The highest peak, ...

Peary Land
Peary Land is a peninsula in northern Greenland, extending into the Arctic Ocean. It reaches from Victoria Fjord in the west to Independence Fjord in the south and southeast, and to the Arctic Ocean in the north, with Cape Morris Jesup, the northernmost point of Greenland's mainland, and Cape Bridgman in the northeast. History Ancient settlements Peary Land was historically inhabited by three separate cultures, during which times the climate was milder than presently. It contains the northernmost ruins on earth, an archaeological site found in 2023. *Independence I culture, Paleo-Eskimo (around 2000 BC, oldest remains dating from 2400 BC) *Independence II culture, Paleo-Eskimo (800 BC to 200 BC) * Thule culture (ancestral to the modern Inuit, around AD 1300) Peary's explorations The area is named after Robert E.

Danmark Expedition
The Denmark expedition (), also known as the Denmark Expedition to Greenland's Northeast Coast and the Danmark Expedition after the ship's name, was an expedition to northeastern Greenland in 1906–1908. Despite being overshadowed by the deaths under tragic circumstances of three of the expedition's leading members ( Ludvig Mylius-Erichsen (1872–1907), Niels Peter Høeg Hagen (1877–1907), and Jørgen Brønlund (1877–1907)), the Denmark expedition was not a failure. It achieved its main cartographic objectives and succeeded in exploring the vast region, drawing accurate charts of formerly unexplored coastlines and fjords, naming numerous geographic features, and gathering a wealth of scientific data. Goals The two-year expedition was conceived and led by Ludvig Mylius-Erichsen, who had previously led the 'Literary Expedition' to Northwest Greenland together with Knud Rasmussen in 1902–1904. The main target of the Denmark expedition was to map the last blank section ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aage Bertelsen
Aage Bertelsen (28 September 1873 – 9 September 1945) was a Danish painter. He was a member of the Denmark Expedition to North-East Greenland. He has also worked for Kähler Keramik in Næstved. Biography Early life and career Aage Bertelsen was born in Næstved where his father, the painter Rudolf Bertelsen, was an art teacher at the Herlufsholm Boarding School. From an early age he was taught to draw and paint by his father as well as by the painter L.A. Ring who was a close friend of the family. He later attended Zahrtmann's art school from 1892 to 1896 while working for Landvæsenet (1894–1897).

Robert Peary
Robert Edwin Peary Sr. (; May 6, 1856 – February 20, 1920) was an American explorer and officer in the United States Navy who made several expeditions to the Arctic in the late 19th and early 20th centuries. He was long credited as being the discoverer of the geographic North Pole in April 1909, having led the first expedition to have claimed this achievement, although it is now considered unlikely that he actually reached the Pole. Peary was born in Cresson, Pennsylvania, but, following his father's death at a young age, was raised in Cape Elizabeth, Maine. He attended Bowdoin College, then joined the United States Coast and Geodetic Survey as a draftsman. He enlisted in the navy in 1881 as a civil engineer. In 1885, he was made chief of surveying for the Nicaragua Canal, which was never built. He visited the Arctic for the first time in 1886, making an unsuccessful attempt to cross Greenland by dogsled. In the Peary expedition to Greenland of 1891–1892, he was muc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Weather Station
An automatic weather station (AWS) is an automated version of the traditional weather station, either to save human labor or to enable measurements from remote areas. An AWS will typically consist of a weather-proof enclosure containing the data logger, rechargeable battery, telemetry (optional) and the meteorological sensors with an attached solar panel or wind turbine and mounted upon a mast. The specific configuration may vary due to the purpose of the system. The system may report in near real time via the Argos System, LoRa and the Global Telecommunications System, or save the data for later recovery. In the past, automatic weather stations were often placed where electricity and communication lines were available. Nowadays, the solar panel, wind turbine and mobile phone technology have made it possible to have wireless stations that are not connected to the electrical grid or hardline telecommunications network. One of the main advantages of an automatic weather station ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valley Glacier
Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. Types of glaciers can range from massive ice sheets, such as the Greenland ice sheet, to small cirque glaciers found perched on mountain tops. Glaciers can be grouped into two main categories: * Ice flow is constrained by the underlying bedrock topography * Ice flow is unrestricted by surrounding topography Unconstrained Glaciers Ice sheets and ice caps Ice sheets and ice caps cover the largest areas of land in comparison to other glaciers, and their ice is unconstrained by the underlying topography. They are the largest glacial ice formations and hold the vast majority of the world's fresh water. Ice sheets Ice sheets are the largest form of glacial formation. They are continent-sized ice masses that span areas over . They are dome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northeast Greenland National Park
Northeast Greenland National Park (, ) is the world's largest national park and the 10th largest protected area (the only larger protected areas consist mostly of sea). Established in 1974, the Northeast Greenland national park expanded to its present size in 1988. It protects of the interior and northeastern coast of Greenland and is larger than the area of Tanzania, but smaller than that of Egypt. This means that the national park is bigger than 166 of the world's 195 countries. It was the first national park to be created in the Kingdom of Denmark and remains Greenland's only national park. It is the northernmost national park in the world and the second-largest by area of any second-level subdivision of any country in the world, trailing only the Qikiqtaaluk Region in Nunavut, Canada. Geography The park shares borders, largely laid out as straight lines, with the Sermersooq municipality in the south and with the Avannaata municipality in the west, partly along the 45° ...
