Harbour Glacier
Harbour Glacier () is a through glacier long and wide, lying on the northwest side of Wiencke Island and extending in a northeast direction from Port Lockroy to the cove east of Noble Peak, in the Palmer Archipelago, Antarctica. It was probably first seen by the Belgian Antarctic Expedition, 1897–99, under Gerlache. The glacier was charted in 1944 by the Falkland Islands Dependencies Survey, who so named it because of its proximity to the harbour of Port Lockroy.

Palmer Archipelago
Palmer Archipelago, also known as Antarctic Archipelago, Archipiélago Palmer, Antarktiske Arkipel or Palmer Inseln, is a group of islands off the northwestern coast of the Antarctic Peninsula. It extends from Tower Island in the north to Anvers Island in the south. It is separated by the Gerlache and Bismarck straits from the Antarctic Peninsula and Wilhelm Archipelago, respectively. Palmer Archipelago is located at . History Adrien de Gerlache, leader of the Belgian Antarctic Expedition (1897–1899), discovered the archipelago in 1898. He named it Archipelago Palmer for American Captain Nathaniel Palmer, who navigated these waters in 1820.

Glacier
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#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, 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.

Wiencke Island
Wiencke Island is an island long and from wide, about in area, the southernmost of the major islands of the Palmer Archipelago, lying between Anvers Island to its north across the Neumayer Channel and the west coast of the Antarctic Peninsula to its east across the Gerlache Strait. Description The rocky island is mostly covered by glaciers, snow and ice. Some small rocky beaches lie on the western and northern sides of the island. There, some grasses, moss and lichens can be found. There are three mountain ridges, with Nemo Peak (Antarctica), Nemo Peak, high, to the north-west; Nipple Peak to the north-east; and Luigi Peak, high, to the south-west. Luigi Peak is the island's summit, despite it never having been completely surveyed. Wiencke's northernmost point is Cape Astrup, a bold, dark-colored bluff discovered by the Belgian Antarctic Expedition, 1897–99. It was named by Adrien de Gerlache for Eivind Astrup, Norway, Norwegian Arctic explorer and member of Robert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Lockroy
Port Lockroy is a bay forming a natural harbour on the north-western shore of Wiencke Island in the Palmer Archipelago to the west of the Antarctic Peninsula. The Antarctic base with the same name, situated on Goudier Island in this bay, includes the most southerly operational post office in the world. The base was left unstaffed from 2020 to 2022 due to the COVID-19 pandemic, though the museum house remained open to individual visits. On 4 October 2022 it was announced that a team of 4 women had been chosen to return to open the base for the summer 2022/23 season. History The bay was discovered in 1904 and named after Edouard Lockroy, a French politician and Vice President of the Chamber of Deputies, who assisted Jean-Baptiste Charcot in obtaining government funding for his French Antarctic Expedition. The harbour was used for whaling between 1911 and 1931. During World War II, the British military Operation Tabarin established the Port Lockroy Station A on tiny Goudier ...

Cove
A cove is a small type of bay or coastal inlet. Coves usually have narrow, restricted entrances, are often circular or oval, and are often situated within a larger bay. Small, narrow, sheltered bays, inlets, creeks, or recesses in a coast are often considered coves. Colloquially, the term can be used to describe a sheltered bay. Geomorphology describes coves as precipitously-walled and rounded cirque-like openings as in a valley extending into or down a mountainside, or in a hollow or nook of a cliff or steep mountainside. A cove can also refer to a corner, nook, or cranny, either in a river, road, or wall, especially where the wall meets the floor. A notable example is Lulworth Cove on the Jurassic Coast in Dorset, England. To its west, a second cove, Stair Hole, is forming. Formation Coves are formed by differential erosion Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gase ...

Belgian Antarctic Expedition
The Belgian Antarctic Expedition of 1897–1899 was the first expedition to winter in the Antarctic region. Led by Adrien de Gerlache de Gomery aboard the RV ''Belgica'', it was the first Belgian Antarctic expedition and is considered the first expedition of the Heroic Age of Antarctic Exploration. Among its members were Frederick Cook and Roald Amundsen, explorers who would later attempt the respective conquests of the North and South Poles. Preparation and surveying In 1896, after a period of intensive lobbying, Adrien Victor Joseph de Gerlache de Gomery purchased the Norwegian-built whaling ship ''Patria'', which, following an extensive refit, he renamed . Gerlache had worked together with the Geographical Society of Brussels to organize a national subscription, but was able to outfit his expedition only after the Belgian government voted in favor of two large subsidies, making it a state-supported undertaking. With a multinational crew that included Roald Amundsen from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerlache
Baron Adrien Victor Joseph de Gerlache de Gomery (; 2 August 1866 – 4 December 1934) was a Belgian officer in the Belgian Royal Navy who led the Belgian Antarctic Expedition of 1897–99. Early years Born in Hasselt in eastern Belgium as the son of an army officer, de Gerlache was educated in Brussels. From a young age he was deeply attracted by the sea, and made three voyages in 1883 and 1884 to the United States as a cabin boy on an ocean liner. He studied Engineering at the Free University of Brussels. After finishing his third year in 1885, he quit the university and joined the Belgian Navy on 19 January 1886. After graduating from the nautical college of Ostend he worked on fishery protection vessels as second and third lieutenant. In October 1887 he signed on as seaman on the ''Craigie Burn'', an English ship, for a voyage to San Francisco, but the ship failed to round Cape Horn and was sold for scrap in Montevideo. He returned to Europe after spending time in Urug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

List Of Glaciers In The Antarctic
There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System).

Glaciology
Glaciology (; ) is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa and Pluto add an extraterrestrial component to the field, which is referred to as "astroglaciology". Overview A glacier is an extended mass of ice formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person who studies glaciers. A glacial geologist ...
