Bertoglio Glacier
Bertoglio Glacier () is a glacier long, flowing from the Conway Range eastward between Cape Lankester and Hoffman Point to the Ross Ice Shelf. It was mapped by the United States Geological Survey from tellurometer surveys and Navy air photos from 1959 to 1963. The glacier was named by the Advisory Committee on Antarctic Names for Commander Lloyd W. Bertoglio, U.S. Navy, commander of the 1960 McMurdo Station McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica.

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.

Conway Range
Conway Range () is a mountain range in the Cook Mountains of Antarctica, on the west edge of the Ross Ice Shelf. Location The Conway Range is in the northeast part of the Cook Mountains. It lies between Mulock Glacier to the north and Carlyon Glacier to the south, both of which empty into the Ross Ice Shelf. The Worcester Range forms the other side of the Mulock Glacier. The Heap Glacier enters the Mulock Glacier to the west of the north end of the range. The range was discovered by the British National Antarctic Expedition, 1901–1904, but the name appears to be first used in the reports of the British Antarctic Expedition, 1907–1909.

Cape Lankester
Cape Lankester () is a high, rounded, snow-covered cape at the south side of the entrance to Mulock Inlet, along the west edge of the Ross Ice Shelf. It was discovered by the British National Antarctic Expedition, 1901–04, and probably named for Sir Edwin Ray Lankester, Director of the British Museum (Natural History) (1898–1907) and founder of the Marine Biological Association The Marine Biological Association of the United Kingdom (MBA) is a learned society with a scientific laboratory that undertakes research in marine biology.

Hoffman Point (Antarctica)
Hoffman Point is an ice-covered coastal headland at the south side of the mouth of Bertoglio Glacier, where the latter flows into the Ross Ice Shelf, Antarctica. It was mapped by the U.S. Geological Survey from tellurometer surveys and Navy air photos, 1959–63, and named by the Advisory Committee on Antarctic Names for Commander G.L.

Ross Ice Shelf
The Ross Ice Shelf is the largest ice shelf of Antarctica (, an area of roughly and about across: about the size of France). It is several hundred metres thick. The nearly vertical ice front to the open sea is more than long, and between high above the water surface. Ninety percent of the floating ice, however, is below the water surface. Most of Ross Ice Shelf is in the Ross Dependency claimed by New Zealand. It floats in, and covers, a large southern portion of the Ross Sea and the entire Roosevelt Island located in the east of the Ross Sea. The ice shelf is named after Sir James Clark Ross, who discovered it on 28 January 1841. It was originally called "The Barrier", with various adjectives including "Great Ice Barrier", as it prevented sailing further south. Ross mapped the ice front eastward to 160° W. In 1947, the U.S. Board on Geographic Names applied the name "Ross Shelf Ice" to this feature and published it in the original U.S. Antarctic Gazetteer. In Januar ...

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 hundredt ...

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] |

McMurdo Station
McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,258 residents, and serves as one of three year-round United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo. By road, McMurdo is 3 kilometres (1.9 mi) from New Zealand's smaller Scott Base. History The station takes its name from its geographic location on McMurdo Sound, named after Lieutenant Archibald McMurdo of . The ''Terror'', commanded by Irish explorer Francis Crozier, along with expedition flagship ''Erebus'' under command of James Clark Ross, first charted the area ...
