Hubbard Glacier (Greenland)
Hubbard Glacier (), is a glacier in northwestern Greenland. Administratively it belongs to the Avannaata municipality. This glacier was named by Robert Peary after Gardiner Greene Hubbard (1822 – 1897), founder and first president of the American Geographical Society.Robert Neff Keely, Gwilym George Davis, ''In Arctic Seas: the Voyage of the Kite with the Peary Expedition,'' 2011 p. 373 Geography The Hubbard Glacier has its terminus in the northern shore of the mid Inglefield Fjord. It discharges from the margins of the Greenland Ice Sheet in Prudhoe Land, flowing roughly from north to south. In the same manner as most neighboring glaciers, it has retreated by approximately in recent years.

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] |

Inglefield Fjord
Inglefield Gulf or Inglefield Fjord (; ) is a fjord in northwestern Greenland. To the west, the fjord opens into the Baffin Bay. Administratively it belongs to the Avannaata municipality. Inglefield Gulf was named after English explorer Edward Augustus Inglefield. Settlements Qaanaaq is located in the northern entrance of the fjord. The village of Qeqertat is located in the Harvard Islands, in the inner area of the fjord. Both are the northernmost communities in the world. Geography Together with Wolstenholme Fjord, Inglefield Gulf is one of the two main indentations in the stretch of coast between Cape York and Cape Alexander.''Prostar Sailing Directions 2005 Greenland and Iceland Enroute,'' p. 77 On the northern shore of the fjord there is a branch, the Bowdoin Fjord, and on the southern there are two, the Academy Bay in the inner fjord with the Leidy Glacier at its head and the narrow Olrik Fjord running roughly from east to west.

Baffin Bay
Baffin Bay (Inuktitut: ''Saknirutiak Imanga''; ; ; ), located between Baffin Island and the west coast of Greenland, is defined by the International Hydrographic Organization as a marginal sea of the Arctic Ocean. It is sometimes considered a sea of the Atlantic Ocean, North Atlantic Ocean. It is connected to the Atlantic via Davis Strait and the Labrador Sea. The narrower Nares Strait connects Baffin Bay with the Arctic Ocean. The bay is not navigable most of the year because of the Arctic ice pack, ice cover and high density of Sea ice, floating ice and icebergs in the open areas. However, a polynya of about , known as the North Water Polynya, North Water, opens in summer on the north near Smith Sound. Most of the aquatic life of the bay is concentrated near that region. Extent The International Hydrographic Organization defines the limits of Baffin Bay as follows: History The area of the bay has been inhabited since BC. Around AD 1200, the initial Dorset culture ...

Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill 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“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. 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 ever ...

Avannaata
Avannaata (, ) is a municipality of Greenland created on 1 January 2018 from the bulk of the former Qaasuitsup municipality. It encompasses an area of 522,700 km2 and has 10,726 inhabitants. Geography In the south, Avannaata is flanked by the Qeqertalik municipality. In the southeast, it is bordered by the Sermersooq municipality; the border runs north–south ( 45° West meridian) through the center of the Greenland ice sheet (), so is free of traffic. In the east and northeast it is bordered by the Northeast Greenland National Park. Pituffik Space Base is an enclave on the Avannaata coast that is administered by the United States Space Force. At the southern end of the municipal coastline are the waters of Disko Bay, although some Disko Bay communities belong to the municipality of Qeqertalik. This bay is an inlet of the larger Baffin Bay, which to the north edges into the island of Greenland in the form of Melville Bay. The coastline of northeastern Baffin B ...

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] |

American Geographical Society
The American Geographical Society (AGS) is an organization of professional geographers, founded in 1851 in New York City. Most fellows of the society are United States, Americans, but among them have always been a significant number of fellows from around the world. The society encourages activities that expands geographical knowledge, and the interpretation of that knowledge so that it can be useful to geographers and other disciplines, especially in a policymaking environment. It is the oldest nationwide geographical organization in the United States. Over the century and a half of its existence, the AGS has been especially interested in three regions: the Arctic, the Antarctic, and Latin America. A signature characteristic of the AGS-sponsored exploration was the requirement that its expeditions produce tangible scientific results. History The AGS was founded by 31 New Yorkers, who were wealthy philanthropists, historians, publishers and editors. Among them were George Folsom, ...

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 they are in endless Glacier#Motion, 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. Tracking Tracking the change in location of a glacier terminus is a method of monitoring a glacier's movement. The end of the glacier terminus is measured from a fixed position in neighboring bedrock periodically over time. The difference in location of a glacier terminus as measured from this fixed position at different time intervals provides a record of the glacier's change. A similar ...

Greenland Ice Sheet
The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of thick and over thick at its maximum. It is almost long in a north–south direction, with a maximum width of at a latitude of 77th parallel north, 77°N, near its northern edge. The ice sheet covers , around 80% of the surface of Greenland, or about 12% of the area of the Antarctic ice sheet. The term 'Greenland ice sheet' is often shortened to GIS or GrIS in scientific literature. Greenland has had major glaciers and ice caps for at least 18 million years, but a single ice sheet first covered most of the island some 2.6 million years ago. Since then, it has both grown and contracted significantly. The oldest known ice on Greenland is about 1 million years old. Due to anthropogenic greenhouse gas emissions, the ice sheet is now the warmest it has been in the past 1000 years, and is losing ice at the fastest rate in at least the past 12,000 years.

Prudhoe Land
Prudhoe ( ) is a town and civil parish in the south of Northumberland, England. It is west of Newcastle upon Tyne and situated on a steep, north-facing hill on the south bank of the River Tyne. Prudhoe had a population of 11,675 at the 2011 census, making it the second largest town in the Tyne Valley after Hexham. Nearby villages include Ovingham, Ovington, Wylam, Stocksfield, Hedley on the Hill and Mickley. History The name derives from the Anglo-Saxon personal name Prud (from , meaning 'proud') and ''hoe'' or ''haugh'', 'a spur of land'. There has been a castle at Prudhoe since ancient times, when England was at war with Scotland. The area now known as Castlefields was a fruit orchard, and the Scots were rumoured to have burnt this orchard while attempting to capture Prudhoe Castle. The castle, originally owned by the d'Umfraville family, then the Percys and now English Heritage, is considered to be the only medieval fortification in Northumberland never to have ...
