Orr Island
The Marshall Archipelago () is an extensive group of large ice-covered islands within the Sulzberger Ice Shelf, Antarctica. Discovery and name Several of the islands in the Marshall Archipelago were discovered and plotted by the Byrd Antarctic Expeditions (ByrdAE; 1928–30 and 1933–35) and by the United States Antarctic Service (USAS; 1939–41), all led by Admiral Richard E. Byrd. The full extent of the archipelago was mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photographs between 1959 and 1965. The name was proposed by Admiral Byrd for General of the Army George C. Marshall, who made financial contributions as a private individual and also, on the same basis, provided advisory assistance to the Byrd expedition of 1933–35. Location The islands of the Marshall Archipelago are scattered throughout the Sulzberger Ice Shelf. The landward side of the ice shelf extends southeast from Howard Heights to McKinley Peak, then run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marie Byrd Land
Marie Byrd Land (MBL) is an unclaimed region of Antarctica. With an area of , it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century. The territory lies in West Antarctica, east of the Ross Ice Shelf and the Ross Sea and south of the Pacific Ocean portion of the Southern Ocean, extending eastward approximately to a line between the head of the Ross Ice Shelf and Eights Coast. It stretches between 158°W and 103°24'W. The inclusion of the area between the Rockefeller Plateau and Eights Coast is based upon Byrd's exploration. Overview Because of its remoteness, even by Antarctic standards, most of Marie Byrd Land (the portion east of 150°W) has not been claimed by any sovereign state. It is by far the largest single unclaimed territory on Earth, with an area of (including Eights Coast, immediately east of Marie Byrd Land). In 1939, United States President Frankl ...

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] |
Radford Island
Radford Island () is an ice-covered island surmounted by several peaks, lying 6 nautical miles (11 km) west of Saunders Mountain in the east part of Sulzberger Ice Shelf. Discovered by the Byrd Antarctic Expedition on the Eastern Flight of 5 December 1929. This feature was mapped as a part of the mainland by the United States Antarctic Service (USAS) (1939–1941) and named " Radford Mountains." It was determined to be an island by the U.S. Geological Survey from air photos taken by the U.S. Navy, 1962–1965. Named by Byrd for V. Admiral Arthur W. Radford, U.S. Navy, Deputy Chief of Naval Operations (Air) during the exploration by U.S. Navy Operation Highjump (1946–1947) and later Admiral and Chairman of the Joint Chiefs The Joint Chiefs of Staff (JCS) is the body of the most senior uniformed leaders within the United States Department of Defense, that advises the president of the United States, the secretary of defense, the Homeland Security Council and the ... of ...

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 ...

Reeves Peninsula
Reeves Peninsula () is a snow-covered peninsula along the north side of Edward VII Peninsula. It extends between the lower ends of the Dalton Glacier and Gerry Glacier into southern Sulzberger Bay. This area was explored from the air and rudely mapped by the Byrd Antarctic Expedition, 1928–30. The peninsula was mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1959–65. Named by 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 ... (US-ACAN), at the suggestion of Admiral R.E. Byrd, for John M. Reeves (of Reeves Brothers, Inc.) who assisted the Byrd Antarctic Expedition of 1928-30 and 1933–35 with contributions of sheepskin-lined coats, and by the development and donation of windproof material for cold wea ...

Guest Peninsula
Guest Peninsula is a snow-covered peninsula about long between the Sulzberger Ice Shelf and Block Bay, on Saunders Coast in the northwest part of Marie Byrd Land, Antarctica. Mitchell Peak, located on the peninsula, was sighted by the first Byrd Antarctic Expedition in 1929. This feature was defined and mapped as "Guest Island" by the United States Antarctic Service Expedition in 1940. It was determined to be a peninsula by U.S. Geological Survey cartographers from air photos taken by the U.S. Navy, 1962–65. It is named for Amy Guest, a contributor to the Second Byrd Antarctic Expedition, 1933–35. As originally charted, the westernmost portion of what was then thought to be Guest Island was within the Ross Dependency claimed by New Zealand, but none of the peninsula is actually within the claimed sector.

Denfeld Mountains
The Denfeld Mountains () are a group of scattered mountains between Crevasse Valley Glacier and Arthur Glacier in the Ford Ranges of Marie Byrd Land. The mountains were explored by the Byrd Antarctic Expeditions (1928–30 and 1933–35) and by the United States Antarctic Service (1939–41) all led by Rear Admiral Richard E. Byrd. They were named for Admiral Louis E.
