Bulfinch Ridge
Bulfinch Ridge () is a ridge long that extends east from the north part of Endeavour Massif, Kirkwood Range, Victoria Land. It was named after Commander C. Bulfinch, U.S. Navy, captain of USCGC Southwind (WAGB-280), USS ''Atka'' in the Ross Sea in Operation Deep Freeze II and III, 1956–57 and 1957–58 seasons.

Endeavour Massif
Endeavour Massif () is a huge, flat-topped massif on the Scott Coast of Victoria Land. The massif extends south from Pa Tio Tio Gap to Fry Glacier and forms the southern block of the Kirkwood Range ( Robertson Massif forms the northern block). Shoulder Mountain, Mount Belgrave and Mount Creak rise from the southern part of the massif. Steep coastal cliffs and projecting ridges mark the eastern margin, but there is a gentle slope west from the massif's broad, plateau-like snow summit. This feature was originally named "Mount Endeavour" by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition in October 1957, but on subsequent New Zealand and U.S. maps the name is identified as an summit northwest of Mount Creak. Following additional mapping by the United States Geological Survey in 1999 and consultation between the Advisory Committee on Antarctic Names and the New Zealand Geographic Board, the name of the southern block of the Kirkwood Range was am ...

Kirkwood Range
The Kirkwood Range () is a massive coastal mountain range in Antarctica, extending north–south between Fry Glacier and Mawson Glacier. A broad low-level platform on the seaward side of the range is occupied by the Oates Piedmont Glacier. It was named by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–58) for Captain Henry Kirkwood, Royal Navy The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against F ..., captain of the supply ship '' Endeavour'' during this period.

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USCGC Southwind (WAGB-280)
USCGC ''Southwind'' (WAGB-280) was a that served in the United States Coast Guard as USCGC ''Southwind'' (WAG-280), the Soviet Navy as the ''Admiral Makarov'', the United States Navy as USS ''Atka'' (AGB-3) and again in the U.S. Coast Guard as USCGC ''Southwind'' (WAGB-280). Construction ''Southwind'' was the third of the of icebreakers operated by the United States Coast Guard. Her keel was laid on 20 July 1942 at the Western Pipe and Steel Company shipyards in San Pedro, California, she was christened by Mrs. Ona Jones and launched on 8 March 1943, and commissioned on 15 July 1944. Her hull was of unprecedented strength and structural integrity, with a relatively short length in proportion to the great power developed, a cut away forefoot, rounded bottom, and fore, aft and side heeling tanks. Diesel electric machinery was chosen for its controllability and resistance to damage. ''Southwind'', along with the other Wind-class icebreakers, was heavily armed for an icebrea ...

Ross Sea
The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land and within the Ross Embayment, and is the southernmost sea on Earth. It derives its name from the British explorer James Clark Ross who visited this area in 1841. To the west of the sea lies Ross Island and Victoria Land, to the east Roosevelt Island and Edward VII Peninsula in Marie Byrd Land, while the southernmost part is covered by the Ross Ice Shelf, and is about from the South Pole. Its boundaries and area have been defined by the New Zealand National Institute of Water and Atmospheric Research as having an area of . The circulation of the Ross Sea is dominated by a wind-driven ocean gyre and the flow is strongly influenced by three submarine ridges that run from southwest to northeast. The circumpolar deep water current is a relatively warm, salty and nutrient-rich water mass that flows onto the continental shelf at certain locations. The Ross Sea is covered with ice ...

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] |
Ridges Of Victoria Land
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
