Swinburne Ice Shelf
The Swinburne Ice Shelf (), is an ice shelf just north of Edward VII Peninsula and the Alexandra Mountains in the southern part of Sulzberger Bay, Antarctica. The ice shelf is long and wide and extends from Fisher Island to White Islands. It was photographed from aircraft and mapped by the Byrd Antarctic Expedition (ByrdAE), 1928–30. Named by Advisory Committee on Antarctic Names (US-ACAN) for Captain H.W Swinburne, Jr., Deputy Commander and Chief of Staff, U.S. Naval Support Force, Antarctica, during Operation Deep Freeze 1970 and 1971.

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 ice s ...

Edward VII Peninsula
King Edward VII Land or King Edward VII Peninsula is a large, ice-covered peninsula which forms the northwestern extremity of Marie Byrd Land in Antarctica. The peninsula projects into the Ross Sea between Sulzberger Bay and the northeast corner of the Ross Ice Shelf, and forms part of the Ross Dependency. Edward VII Peninsula is defined by the Ross Ice Shelf on the southwest, Okuma Bay on the west, and to the east by Sulzberger Bay and the Saunders Coast, all essentially on the Ross Sea / Southern Ocean in Antarctica. The northwest extremity of the peninsula is Cape Colbeck. Edward VII Peninsula is located at . The western coast is Shirase Coast. In the north and east the Swinburne Ice Shelf is located. Edward VII Peninsula was discovered on 30 January 1902 by the British National Antarctic Expedition (BrNAE) (1901–1904) under Robert Falcon Scott, who named it King Edward VII Land for King Edward VII of the United Kingdom. The coastline was further explored by the Nimrod E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexandra Mountains
:''See also Queen Alexandra Range'' Alexandra Mountains () is a group of low, separated mountains in the north portion of Edward VII Peninsula, just southwest of Sulzberger Bay in Marie Byrd Land, Antarctica. Discovered in January–February 1902 by the British National Antarctic Expedition during an exploratory cruise of the ''Discovery'' along the Ross Ice Shelf. Named for Alexandra, then Queen of the United Kingdom. List of mountains * Balsley Peak () is a distinctive peak (c. 1100m) located 1.4 nautical miles (2.6 km) southeast of La Gorce Peak. Named by Advisory Committee on Antarctic Names (US-ACAN) (2004) after James R. Balsley, U.S. Geological Survey, who conducted airborne magnetometer near this peak during U.S. Navy Operation Highjump, 1946–47; later Chief, Branch of Geophysics, United States Geological Survey (USGS). * Bowman Peak () is a peak on the south side of Butler Glacier, in the Alexandra Mountains.

Sulzberger Bay
Sulzberger Bay () is a bay between Fisher Island and Vollmer Island, along the coast of King Edward VII Land. Discovered by the Byrd Antarctic Expedition on December 5, 1929, and named by Byrd for Arthur H. Sulzberger, publisher of ''The New York Times'', a supporter of the Byrd expeditions in 1928–1930 and 1933–1935. The Sulzberger Bay indents the front of the Sulzberger Ice Shelf (), an ice shelf about long and wide bordering the coast of Marie Byrd Land between Edward VII Peninsula and Guest Peninsula. The ice shelf was observed and roughly mapped by the Byrd Antarctic Expedition (1928–1930). Sulzberger Basin () is an undersea basin on the central Ross shelf named in association with the Sulzberger Bay. Iceberg formation The ice shelf released icebergs within a day of the 2011 Tōhoku earthquake and tsunami. Scientists have linked the ice calving to the tsunami reaching the ice shelf, some away from the earthquake epicenter. The main iceberg was approximately th ...

Fisher Island (Antarctica)
Fisher Island is an ice-covered island long, lying just north of Edward VII Peninsula where it marks the Western side of the entrance to Sulzberger Bay. Mapped from surveys by the USGS and U.S. Navy air photos (1959–65). Named in 1966 by US-ACAN for Wayne Fisher of the United States Department of State.

White Islands
The White Islands are a group of ice-covered islands extending north–south for about . They lie at the east margin of Swinburne Ice Shelf and near the terminus of Butler Glacier in the south part of Sulzberger Bay. This feature is rudely delineated on the map of the Byrd Antarctic Expedition, 1928–30, as "low ice cliffs" that rise above the level of the ice shelf. The islands were mapped in detail by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1959–65. The name was applied by Advisory Committee on Antarctic Names (US-ACAN) at the suggestion of Admiral R.E. Byrd. Named for Dr. Paul Dudley White, internationally renowned specialist on heart diseases, who was a consultant on medical matters in regard to U.S. Navy 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 ...

Operation Deep Freeze
Operation Deep Freeze (OpDFrz or ODF) is codename for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on. (There was an initial operation before Admiral Richard Byrd proposed 'Deep Freeze'). Given the continuing and constant US presence in Antarctica since that date, "Operation Deep Freeze" has come to be used as a general term for US operations in that continent, and in particular for the regular missions to resupply US Antarctic bases, coordinated by the United States military. Task Force 199 was involved. Prior to International Geophysical Year The U.S. Navy already had a record of earlier exploration in Antarctica. As early as 1839, Captain Charles Wilkes led the first U.S. Naval expedition into Antarctic waters. In 1929, Admiral Richard E. Byrd established a naval base at Little America I, led an expedition to explore further inland, and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
