Abbot Ice Shelf
The Abbot Ice Shelf () is an ice shelf long and wide, bordering Eights Coast from Cape Waite to Pfrogner Point in Antarctica. Thurston Island lies along the northern edge of the western half of this ice shelf; other sizable islands (Sherman Island, Carpenter Island, Dustin Island, Johnson Island, McNamara Island, Farwell Island and Dendtler Island) lie partly or wholly within this shelf. Location The Abbott Ice Shelf extends to the south of Thurston Island, Dustin Island, McNamara Island, and Farwell Island all of which lie between the ice shelf and the Bellingshausen Sea. It occupies the whole of Peacock Sound in its western part. The Demas Ice Tongue extends into the Amundsen Sea from the west end of the ice shelf. Islands embedded in the bbott Ice Shelf include the Trice Islands, Sherman Island, Carpenter Island, Johnson Island, Lepley Nunatak and Dendtler Island.

Ice Shelf
An ice shelf is a large platform of glacial ice floating on the ocean, fed by one or multiple tributary glaciers. Ice shelves form along coastlines where the ice thickness is insufficient to displace the more dense surrounding ocean water. The boundary between the ice shelf (floating) and grounded ice (resting on bedrock or sediment) is referred to as the grounding line; the boundary between the ice shelf and the open ocean (often covered by sea ice) is the ice front or calving front. Ice shelves are found in Antarctica and the Arctic (Greenland, Northern Canada, and the Russian Arctic), and can range in thickness from about . The world's largest ice shelves are the Ross Ice Shelf and the Filchner-Ronne Ice Shelf in 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. Typically, a shelf front will extend forward for years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

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 (exploration base), Little America IV. The operation was organized by Rear admiral (United States)#Rear admiral, Rear Admiral Richard E. Byrd, Jr., USN, 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, 70 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 ...
