Hovgaard Island (Greenland)
Hovgaard Island ( da, Hovgaard Ø) is a large uninhabited island of the Greenland Sea, Greenland. The island was named after Andreas Hovgaard, a Polar explorer and officer of the Danish Navy who led an expedition to the Kara Sea on steamship ''Dijmphna'' in 1882–83.Hovgaard Ø. In: Anthony K. Higgins: ''Exploration history and place names of northern East Greenland.'' Geological Survey of Denmark and Greenland Bulletin Bd. 21, 2010. Copenhagen 2010, Polar climate prevails in Hovgaard Island. The average annual temperature in the area is -17 °C. The warmest month is July when the average temperature reaches -2 °C and the coldest is February when the temperature sinks to -29 °C. Geography Hovgaard Island is a coastal island located to the south of the Holm Land Peninsula. To the west, further inshore, lies smaller Lynn Island and to the east and the southeast the Greenland Sea. The Dijmphna Sound limits the island to the west and north, and to the southwest ...

Andreas Peter Hovgaard
Andreas Peter Hovgaard (1 November 1853 – 15 March 1910) was a Danish naval officer and Arctic explorer. Hovgaard became a sub-lieutenant of the Danish Navy in 1874, rising to the rank of Lieutenant (navy), lieutenant in 1876, Captain (naval), captain in 1888 and Commander in 1901. He retired from active service in 1909. Career Andreas Hovgaard was the son of Ole Anton Hovgaard (1821–1891) and Louise Charlotte Munch (1823–1872). Little is known about his early life, except that he joined the Danish Navy and quickly rose in the ranks. In 1878 Hovgaard, as a young lieutenant, became a member of Adolf Erik Nordenskiöld's Vega Expedition in which he was in charge of making meteorological as well as geomagnetic observations. Shortly after returning to Denmark he married Sophie Christiane Nielsen (1856–1934) and published his report ''Nordenskiölds rejse omkring Asien og Europa'' about the first Arctic expedition that navigated successfully through the Northeast Passage.

Nioghalvfjerd Fjord
Nioghalvfjerdsbrae (), sometimes referred to as " 79 N Glacier", is a large glacier located in King Frederick VIII Land, northeastern Greenland. It drains an area of of the Greenland Ice Sheet with a flux (quantity of ice moved from the land to the sea) of per year, as measured for 1996. The glacier has two calving fronts where the glacier meets the ocean, separated by Hovgaard Island. In July 2020, the northern offshoot, the Spalte Glacier broke away from Nioghalvfjerdsbrae and completely disintegrated. History This glacier was named by the ill-fated Denmark expedition 1906-1908 because it lies at a latitude of 79°. The name had been meant to be temporary, but it acquired a new significance when it was deemed to be the place where expedition leader Ludvig Mylius-Erichsen, as well as cartographer Niels Peter Høeg Hagen, had died according to Jørgen Brønlund's diary. Since 1990 Greenland's longest persistent supraglacial stream runs on the glacier, 73 km long in 2011, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alabama Expedition
''Two Against the Ice'' is a non-fiction book authored by Danish explorer Ejnar Mikkelsen. The book details the author's exploration into Greenland, a journey made with his compatriot Iver P. Iversen in 1910. The book was originally published in Danish (1955) and later translated into English by Maurice Michael (first published in 1957). Summary Mikkelsen recounts his round-trip 2,500 mile sledge journey from Shannon Island to Danmark Fjord. A task which soon became a battle for survival as rations ran low, and the sled dogs began to starve to death, or were intentionally shot in order to provide food for the other dogs. The two adventurers became so hungry that they began to hallucinate. In a notable moment that typifies the hunger pains that the men were suffering, Iversen no longer wished to carry his rifle out of a fear he may be compelled to shoot Mikkelsen. The purpose of their travels was to locate the maps and journals of previous explorer Mylius Erichsen of the ill- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ejnar Mikkelsen
Ejnar Mikkelsen (December 23, 1880 – May 1, 1971) was a Danish polar explorer and author. He is most known for his expeditions to Greenland. Biography Mikkelsen was born in Vester Brønderslev, Jutland. He served in the Georg Carl Amdrup expedition to Christian IX Land, East Greenland (1900), and in the Baldwin-Ziegler North Pole Expedition to Franz Joseph Land (1900–02). With Ernest de Koven Leffingwell he organized the Anglo-American polar expedition which wintered off Flaxman Island, Alaska, in 1906–07. They lost their ship, but in a sledge journey over the ice they located the continental shelf of the Arctic Ocean, 65 miles (105 km) offshore, where in 2 miles (3 km) the sea increased from 50 meters (164 ft) to more than 690 meters (2264 ft) in depth.Mills, William James (2003"Mikkelsen, Ejnar (1880–1971)"''Exploring polar frontiers: a historical encyclopedia, Volume 1'' pp 426 ff, ABC-CLIO , Organizing an expedition to map out the northeast ...

Georg Carl Amdrup
Vice Admiral Sir Georg Carl Amdrup (Copenhagen, Denmark, November 19, 1866 – Copenhagen, January 15, 1947), RN was a Danish naval officer, Vice Admiral and Greenland researcher. Career In 1884, Amdrup, of the Royal Danish Navy, was sent to Amassalik. After wintering, he explored the coast to the north, including an examination of the Kangerlussuaq Fjord, known until then only from Inuit reports. He mapped a large length of coastline while collecting many geological and ethnological finds. By July 1885, he reached Aggas Island (67° 22' North), the furthest north of this survey. Carlsbergfondet Expedition til Ost-Gronland Lieutenant Amdrup was the leader of a major Danish expedition in 1898-1900, the Carlsberg Foundation Expedition to East Greenland (Carlsbergfondet Expedition til Ost-Gronland). With him were botanist Christian Krause, ornithologist Knud Poulsen, and the sailors, A. Jakobsen and Soren P. Nielsen. They left Copenhagen on August 16, 1898, sailing from Copen ...

Alfred Wegener
Alfred Lothar Wegener (; ; 1 November 1880 – November 1930) was a German climatologist, geologist, geophysicist, meteorologist, and polar researcher. During his lifetime he was primarily known for his achievements in meteorology and as a pioneer of polar research, but today he is most remembered as the originator of continental drift hypothesis by suggesting in 1912 that the continents are slowly drifting around the Earth (German: '). His hypothesis was controversial and widely rejected by mainstream geology until the 1950s, when numerous discoveries such as palaeomagnetism provided strong support for continental drift, and thereby a substantial basis for today's model of plate tectonics. Wegener was involved in several expeditions to Greenland to study polar air circulation before the existence of the jet stream was accepted. Expedition participants made many meteorological observations and were the first to overwinter on the inland Greenland ice sheet and the first to ...

Denmark Expedition
The Denmark expedition ( da, Danmark-ekspeditionen), also known as the Denmark Expedition to Greenland's Northeast Coast, and as the Danmark Expedition after the ship, was an expedition to the northeast of Greenland in 1906–1908. Despite being overshadowed by the death in tragic circumstances of the main exploration team, including 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. Purposes 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.

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operational Navigation Chart B-9, 1st 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 ...

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.

Dijmphna Sound
The Dijmphna Sound ( da, Dijmphna Sund) is a sound in King Frederick VIII Land, Northeast Greenland. Administratively it is part of the Northeast Greenland National Park zone. History The sound was named by the 1906-1908 Denmark expedition after steamer ''Dijmphna'', on which Danish Naval officer Andreas Peter Hovgaard attempted to reach and map the area to the north of the Taymyr Peninsula in 1882–1883, but ended up stuck in the Kara Sea pack ice.''Catalogue of place names in northern East Greenland'', Geological Survey of Denmark and Greenland A polynya forms at the foot of the steep cliffs of Mallemuk Mountain so that there is sometimes open water in that area, even in the winter.Spencer Apollonio, ''Lands That Hold One Spellbound: A Story of East Greenland,'' 2008, pp. 110-116 Geography The sound is structurally a fjord forming a channel that runs roughly westwards between the southern shore of Holm Land by Mallemuk Mountain to the north and Cape H.
