Quito Glacier
Quito Glacier () is a glacier draining the northeast slopes of Mount Plymouth and flowing northeastwards into the sea west of Canto Point in north Greenwich Island, South Shetland Islands. It was named after the capital of Ecuador, c. 1990, by the Ecuadorian Antarctic Expedition.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenwich Island
Greenwich Island (variant historical names ''Sartorius Island'', ''Berezina Island'') is an island long and from (average ) wide, lying between Robert Island and Livingston Island in the South Shetland Islands. Surface area . The name Greenwich Island dates back to at least 1821 and is now established in international usage. The Chilean base Arturo Prat and the Ecuadorian base Pedro Vicente Maldonado are situated on the northeast and north coast of the island respectively. Chilean scientists have claimed that Amerinds visited the area, due to stone artifacts recovered from bottom-sampling operations off the island; however, the artefacts — two arrowheads — were later found to have been planted.

South Shetland Islands
The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes. The islands have been claimed by the United Kingdom since 1908 and as part of the British Antarctic Territory since 1962. They are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province) and Argentina (since 1943, as part of Argentine Antarctica, Tierra del Fuego Province). Several countries maintain research stations on the islands. Most of them are situated on King George Island, benefitting from the airfield of the Chilean base Eduardo Frei. There are sixteen research stations in different parts of the islands, with Chilean stations being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Mount Plymouth
Mount Plymouth or Mount Osorno is a conspicuous peak rising to 520 m in the northeast extremity of Dryanovo Heights, Greenwich Island in the South Shetland Islands, Antarctica. The peak has precipitous and partly ice-free northern slopes, and surmounts Teteven Glacier to the northwest, Quito Glacier to the northeast and Traub Glacier to the southeast. The feature was charted by the Discovery Investigations and named after the city of Plymouth, England. Location The peak is located at which is 3.1 km east by north of Sevtopolis Peak, 5.1 km west-southwest of Spark Point, 4.47 km north-northeast of Tile Ridge and 4.9 km northeast of Lloyd Hill (British mapping in 1935 and 1968, Chilean in 1947, Argentine in 1953, and Bulgarian in 2005 and 2009).

Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecuadorian Antarctic Expedition
Ecuadorians ( es, ecuatorianos) are people identified with the South American country of Ecuador. This connection may be residential, legal, historical or cultural. For most Ecuadorians, several (or all) of these connections exist and are collectively the source of their being ''Ecuadorian''. Numerous indigenous cultures inhabited what is now Ecuadorian territory for several millennia before the expansion of the Inca Empire in the fifteenth century. The Las Vegas culture of coastal Ecuador is one of the oldest cultures in the Americas. The Valdivia culture is another well-known early Ecuadorian culture. Spaniards arrived in the sixteenth century, as did sub-Saharan Africans who were enslaved and transported across the Atlantic by Spaniards and other Europeans. The modern Ecuadorian population is principally descended from these three ancestral groups. As of 2010, 77.4% of the population identified as "Mestizos", a mix of Spanish and Indigenous American ancestry, up from 71.9% in ...

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 ...
