Bondeson Glacier
Robb Glacier () is a glacier about 40 nautical miles (70 km) long that flows through the Ross Dependency to enter the west coast of the Ross Ice Shelf in Antarctica. Location The Robb Glacier flows from Clarkson Peak north along the east side of Softbed Ridges to the Ross Ice Shelf at Cape Goldie. It flows between the Queen Elizabeth Range to the west and the Holland Range to the east. To the north of Softbed Ridges it converges with Lowery Glacier, which is to the west, but the two glaciers separate when they reach Taylor Hills. Its mouth is southeast of the Lowery Glacier and the Nimrod Glacier. It is north of the Lennox-King Glacier and the Beardmore Glacier. Named by the expedition after Murray Robb, leader of the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1959–60), who traversed this glacier to reach Lowery Glacier. Mouth Cape Goldie A cape at the south side of the mouth of Robb Glacier, overlooking the Ross Ice Shelf. Discovered by the ...

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 the 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, Antarctica, Roosevelt Island located in the east of the Ross Sea. The ice shelf is named after James Clark Ross, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lowery Glacier
Lowery Glacier () is a glacier about long, a tributary of the Nimrod Glacier, which enters the west of the Ross Ice Shelf, Antarctica. Location The Lowery Glacier flows north from Prince Andrew Plateau, Antarctica, along the east side of the Queen Elizabeth Range to enter Nimrod Glacier. To the north of Softbed Ridges it converges with Robb Glacier, but the two glaciers separate when they reach Taylor Hills. It was named by the New Zealand Geological and Topographical Survey Expedition (1959–60) for J.H. Lowery who, as a member of a field party, suffered injuries when a Sno-cat broke through a crevasse bridge off Cape Selborne in November 1959. Icefalls Arai Terraces . A series of crevassed terraces and icefalls close southward of Fazekas Hills, near the head of Lowery Glacier. So named by the NZGSAE (1959-60) because the feature is a natural barrier to sledge travel which the party was unable to traverse. Arai is the Maori term for barrier. Left tributaries Tri ...

OpDFrz
Operation Deep Freeze is the code name 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. For a few decades the missions were led by the United States Navy, though the Air National Guard and National Science Foundation are also important parts of the missions. In Antarctica, when the polar dawn starts late in the year things begin warming up and the mission usually runs from late in the year to early the next year before the months of darkness ...

Beardmore Glacier
The Beardmore Glacier in Antarctica is one of the largest valley glaciers in the world, being long and having a width of . It descends about from the Antarctic Plateau to the Ross Ice Shelf and is bordered by the Commonwealth Range of the Queen Maud Mountains on the eastern side and the Queen Alexandra Range of the Central Transantarctic Mountains on the western. Its mouth is east of the Lennox-King Glacier. It is northwest of the Ramsey Glacier. Early exploration The glacier is one of the main passages through the Transantarctic Mountains to the great polar plateau beyond, and was one of the early routes to the South Pole despite its steep upward incline. The glacier was discovered and climbed by Ernest Shackleton during his Nimrod Expedition, ''Nimrod'' Expedition of 1908. Although Shackleton turned back at latitude 88° 23' S, just from the South Pole, he established the first proven route towards the pole and, in doing so, became the first person to set foot up ...

Lennox-King Glacier
Lennox-King Glacier is a large valley glacier, about long that flows east into the Ross Ice Shelf. Location Lennox-King Glacier drains Bowden Névé and flows northeast between the Holland Range and the Queen Alexandra Range of Antarctica to enter Richards Inlet and the Ross Ice Shelf. The Law Glacier supplies ice to the Lennox-King Glacier, leading some glaciologists to refer to it as the Law/Lennox-King Glacier system or Law-Lennox-King glacier corridor. Its mouth is south of the Robb Glacier and west of the Beardmore Glacier. Lennox-King Glacier was named by the New Zealand Geological Survey Antarctic Expedition (1959–60) for Lieutenant Commander James Lennox-King, Royal New Zealand Navy, leader at Scott Base, 1960. Mouth Richards Inlet . A large ice-filled inlet at the mouth of Lennox-King Glacier, opening to the Ross Ice Shelf just southeast of Lewis Ridge. Named by the NZGSAE (1959–60) for R. W.

Nimrod Glacier
The Nimrod Glacier () is a major glacier about long, flowing from the polar plateau in a northerly direction through the Transantarctic Mountains into the Ross Ice Shelf, Antarctica. Location The Nimrod Glacier flows north between the Geologists and Miller Ranges, then northeasterly between the Churchill Mountains and Queen Elizabeth Range, and finally spills into Shackleton Inlet and the Ross Ice Shelf between Capes Wilson and Lyttelton. It was photographed from the air by USN Operation Highjump, 1946–47. The name, given by US-ACAN, is in association with Shackleton Inlet and is for the ''Nimrod'', the ship of the British Antarctic Expedition (1907–09) under Ernest Shackleton. The mouth of the glacier is southeast of the Starshot Glacier and the Nursery Glacier. It is north of Robb Glacier. Icefalls Worsley Icefalls Icefalls near the head of Nimrod Glacier.

Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and 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“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. 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 ever ...
