Gillett Ice Shelf () is a narrow ice shelf occupying an indentation of the coast off the Wilson Hills between the peninsula containing the Holladay Nunataks and the Anderson Peninsula.

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 ...

Wilson Hills
Wilson Hills () is a group of scattered hills, nunataks and ridges that extend NW-SE for about between Matusevich Glacier and Pryor Glacier in Antarctica. They were discovered by Lieutenant Harry Pennell, Royal Navy, on the Terra Nova Expedition in February 1911 during Robert Falcon Scott's last expedition, and named after Edward Adrian Wilson, a zoologist with the expedition, who perished with Scott on the return journey from the South Pole. Geological features Axthelm Ridge Axthelm Ridge () is a narrow ridge, 4 miles (6 km) long, 1.5 miles (2.4 km) southeast of Parkinson Peak. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1960–63. Named by Advisory Committee on Antarctic Names (US-ACAN) for Commander Charles E. Axthelm, U.S. Navy, Flag Secretary to the Commander of the U.S. Naval Support Force, Antarctica, during Operation Deep Freeze 1969 and 1970; executive officer on the USS ''Glacier'' during Operation Deep Fre ...

Peninsula
A peninsula (; ) is a landform that extends from a mainland and is surrounded by water on most, but not all of its borders. A peninsula is also sometimes defined as a piece of land bordered by water on three of its sides. Peninsulas exist on all continents. The size of a peninsula can range from tiny to very large. The largest peninsula in the world is the Arabian Peninsula. Peninsulas form due to a variety of causes. Etymology Peninsula derives , which is translated as 'peninsula'. itself was derived , or together, 'almost an island'. The word entered English in the 16th century. Definitions A peninsula is usually defined as a piece of land surrounded on most, but not all sides, but is sometimes instead defined as a piece of land bordered by water on three of its sides. A peninsula may be bordered by more than one body of water, and the body of water does not have to be an ocean or a sea. A piece of land on a very tight river bend or one between two rivers is sometimes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anderson Peninsula
The Anderson Peninsula () is a low ice-covered peninsula, long, terminating in Belousov Point. It lies between Gillett Ice Shelf and Suvorov Glacier on the coastal margin of the Wilson Hills of Antarctica. It was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos in 1960–64, and named by the Advisory Committee on Antarctic Names for Lieutenant (later Captain) Richard E. Anderson, Civil Engineer Corps, U.S. Navy, base public works officer at McMurdo Sound during Operation Deep Freeze I and II. He wintered over in the McMurdo area during the latter operation in 1957. The peninsula is situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams Cape Williams () is an ice-covered cape in Antarctica. It is the termination of Buell Peninsula at the east side of the terminus of Lillie Glacier at the lower ends of George Glacier and Zykov Glacier.

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredth an ...

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] |
