Moscow University Ice Shelf
Moscow University Ice Shelf () is a narrow ice shelf, about long, which fringes the Sabrina Coast of Antarctica between Totten Glacier and Paulding Bay. Dalton Iceberg Tongue extends north from the eastern part of the shelf. The feature was partly delineated from aerial photographs taken by U.S. Navy Operation Highjump in 1946–47, and further photographed and mapped by the Australian National Antarctic Research Expeditions and the Soviet Antarctic Expedition in 1958. It was named by the Soviet expedition after Moscow University. See also * List of glaciers * List of Antarctic ice shelves This is a list of Antarctic ice shelves.

Ice Shelf
An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. The thickness of ice shelves can range from about to . In contrast, sea ice is formed on water, is much thinner (typically less than ), and forms throughout the Arctic Ocean. It is also found in the Southern Ocean around the continent of Antarctica. The movement of ice shelves is principally driven by gravity-induced pressure from the grounded ice. That flow continually moves ice from the grounding line to the seaward front of the shelf. In steady state, about half of Antarctica's ice shelf mass is lost to basal melt and half is lost to calving, but the relative importance of each process varies significantly between ...

Sabrina Coast
Sabrina Coast () is that portion of the coast of Wilkes Land, Antarctica, lying between Cape Waldron, at 115° 33' E, and Cape Southard, at 122° 05' E. John Balleny has long been credited with having seen land in March 1839 at about 117° E. The United States Exploring Expedition under Lt. Charles Wilkes approached this coast in February 1840 and indicated its general configuration as shown in part by "Totten High Land" on his 1840 chart. In 1931 the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Douglas Mawson Sir Douglas Mawson OBE FRS FAA (5 May 1882 – 14 October 1958) was an Australian geologist, Antarctic explorer, and academic. Along with Roald Amundsen, Robert Falcon Scott, and Sir Ernest Shackleton, he was a key expedition leader duri ... saw what appeared to be land in this longitude about one degree farther south than that reported by Balleny and Wilkes. In recognition of Balleny's effort, Mawson retained the name of the cutt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Totten Glacier
Totten Glacier is a large glacier draining a major portion of the East Antarctic Ice Sheet, through the Budd Coast of Wilkes Land in the Australian Antarctic Territory. The catchment drained by the glacier is estimated at , extending approximately into the interior and holds the potential to raise sea level by at least . Totten drains northeastward from the continental ice but turns northwestward at the coast where it terminates in a prominent tongue close east of Cape Waldron. It was first delineated from aerial photographs taken by USN Operation Highjump (1946–47), and named by Advisory Committee on Antarctic Names (US-ACAN) for George M. Totten, midshipman on of the United States Exploring Expedition (1838–42), who assisted Lieutenant Charles Wilkes with correction of the survey data obtained by the expedition. Totten Ice Shelf is a floating portion of Totten Glacier, laterally bounded by the Aurora Subglacial Basin to the south and Law Dome to the north. The ice shelf ...

Paulding Bay
Paulding Bay is a bay along the coast of Antarctica just west of Clark Point. The outer portions of the bay are bounded by the Moscow University Ice Shelf and the Voyeykov Ice Shelf. It was mapped by G. D. Blodgett (1955) from aerial photographs obtained by USN Operation Highjump (1946–47), and named by the Advisory Committee on Antarctic Names (US-ACAN) for James K. Paulding, Secretary of the Navy under President Martin Van Buren. Paulding had previously served as U.S. Navy agent for New York and was instrumental in the outfitting of the United States Exploring Expedition (1838–42) under Lt. Charles Wilkes Charles Wilkes (April 3, 1798 – February 8, 1877) was an American naval officer, ship's captain, and explorer. He led the United States Exploring Expedition (1838–1842).

Dalton Iceberg Tongue
The Dalton Iceberg Tongue () is a large iceberg tongue that extends seaward from the eastern part of Moscow University Ice Shelf. The feature was partly delineated from air photos taken by U.S. Navy Operation Highjump (1946–47). It was mapped on the basis of observation by Phillip Law from Australian National Antarctic Research Expeditions (ANARE ) aircraft in 1958, and visited in February 1960 by the ANARE (''Magga Dan The Buddhist path (''marga'') to liberation, also referred to as awakening, is described in a wide variety of ways.

Operation Highjump
Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America IV. The operation was organized by Rear Admiral Richard E. Byrd, Jr., USN (Ret), Officer in Charge, Task Force 68, and led by Rear Admiral Ethan Erik Larson, USN, Commanding Officer, Task Force 68. Operation HIGHJUMP commenced 26 August 1946 and ended in late February 1947. Task Force 68 included 4,700 men, 13 ships, and 33 aircraft. HIGHJUMP's objectives, according to the U.S. Navy report of the operation, were: # Training personnel and testing equipment in frigid conditions; # Consolidating and extending the United States' sovereignty over the largest practicable area of the Antarctic continent (publicly denied as a goal before the expedition ended); # Determining the feasibility of establishing, maintaining, and utilizing bases in the Antarctic an ...

Australian National Antarctic Research Expeditions
The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involvement in south polar regions since as early as Douglas Mawson's Australasian Antarctic Expedition in 1911. Further Australian exploration of the Antarctic continent was conducted during the British Australian and New Zealand Antarctic Research Expedition (BANZARE), which was conducted over the years 1929–1931. The Australian National Antarctic Research Expeditions were established in 1947 with expeditions to Macquarie Island and Heard Island. In 1948 the Australian Antarctic Division (AAD) was established to administer the expedition program. ANARE Name The name ANARE fell out of official use in the early 2000s. However current and former Australian Antarctic expeditioners continue to use the term informally as a means of identi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Glaciers
A glacier ( ) or () is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. Because glacial mass is affected by long-term climate changes, e.g., precipitation, mean temperature, and cloud cover, glacial mass changes are considered among the most sensitive indicators of climate change. There are about 198,000 to 200,000 glaciers in the world. Glaciers by continent Africa Africa, specifically East Africa, has contained glacial regions, possibly as far back as the last glacier maximum 10 to 15 thousand years ago. Seasonal snow does exist on the highest peaks of East Africa as well as in the Drakensberg Range of South Africa, the Stormberg Mountains, and the Atlas Mountains in Morocco. Current ...
