Jackson Pond
Jackson Pond is a freshwater frozen pond midway between the terminus of Wright Upper Glacier and Anvil Pond in the Labyrinth, McMurdo Dry Valleys, Antarctica. It was named by the Advisory Committee on Antarctic Names in 2004 after J.K. Jackson of the Department of Geology at Northern Illinois University, DeKalb, Illinois, a member of the core legging and processing team during the McMurdo Dry Valleys Drilling Project Vice-Admiral Archibald McMurdo (24 September 1812 – 11 December 1875) was a Scottish naval officer and polar explorer after whom Antarctica's McMurdo Sound, McMurdo Station, McMurdo Ice Shelf, McMurdo Dry Valleys and McMurdo–South Pole High ..., 1974–75.

McMurdo Dry Valleys
The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby glaciers. The rocks here are granites and gneisses, and glacial tills dot this bedrock landscape, with loose gravel covering the ground. It is one of the driest places on Earth and has not seen rain for nearly two million years. The region is one of the world's most extreme deserts, and includes many features including Lake Vida, a saline lake, and the Onyx River, a meltwater stream and Antarctica's longest river. Although no living organisms have been found in the permafrost here, endolithic photosynthetic bacteria have been found living in the relatively moist interior of rocks, and anaerobic bacteria, with a metabolism based on iron and sulfur, live under the Taylor Glacier. The valleys are located within the McMurdo Valleys A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wright Upper Glacier
Wright Upper Glacier () is an ice apron at the upper west end of Wright Valley in Asgard Range, Antarctica. It is formed by a glacier flowing east from the inland ice plateau. Named by the Victoria University of Wellington Antarctic Expedition (VUWAE) (1958–59) for C.S. Wright, a member of the British Antarctic Expedition (1910–13), after whom the "Wright Glacier" (adjusted to Wright Lower Glacier by the VUWAE) was named. Two massive icefalls descend from the plateau into the Wright Upper Glacier, the wide and tall Airdevronsix Icefalls and the equally tall wide Warren Icefalls, which was named by the Advisory Committee on Antarctic Names (US-ACAN) in 2004 for Alden Warren, a longtime photographer (scientific and technical) with the United States Geological Survey, involved in documenting maps of Antarctica. Vortex Col is a col leading from the plateau into the south side of the glacier. At this locality, winds carrying clouds of snow from the polar plateau are deflected ...

Anvil Pond
The Labyrinth () is an extensive flat upland area which has been deeply eroded, at the west end of Wright Valley, in Victoria Land, Antarctica. It was so named by the Victoria University of Wellington Antarctic Expedition (1958–59) because the eroded dolerite of which it is formed gives an appearance of a labyrinth.

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

McMurdo Dry Valleys Drilling Project
Vice-Admiral Archibald McMurdo (24 September 1812 – 11 December 1875) was a Scottish naval officer and polar explorer after whom Antarctica's McMurdo Sound, McMurdo Station, McMurdo Ice Shelf, McMurdo Dry Valleys and McMurdo–South Pole Highway are named. Early life Archibald William McMurdo was born on September 24, 1812 in Scotland. He was the son of Lieutenant Colonel Archibald McMurdo and grandson of John McMurdo, a chamberlain at Drumlanrig Castle. Career McMurdo joined the Royal Navy on 6 October 1824, at the age of 12. He was promoted to Lieutenant in 1836 for his skill and courage in saving the crew of a shipwrecked whaler from hostile New Zealand natives. He achieved the rank of Commander in 1843 and Captain in 1851. His career included two discovery expeditions aboard HMS ''Terror'', the first to Hudson Bay (1836-1837), the second to Antarctica (1839-1842). In 1836 he served on HMS Volage during its voyage to East India. During the Antarctica voyage, McMurdo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakes Of Victoria Land
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
