Gipps Ice Rise
Gipps Ice Rise () is a roughly elliptical ice rise, long and bounded by an ice cliff on all sides, lying at the edge of the Larsen Ice Shelf about northeast of Hearst Island. The feature was discovered by William R. MacDonald of the United States Geological Survey (USGS), December 18, 1966, while on a photographic mapping mission of this area aboard a Super Constellation aircraft crewed by the U.S. Navy VXE-6 Squadron. The ice rise was first mapped from these photos by the USGS. The name was proposed by the UK Antarctic Place-Names Committee for Derek R. Gipps, a Senior Executive Officer with the British Antarctic Survey The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute.

Ice Rise
An ice rise is a clearly defined elevation of the otherwise very much flatter ice shelf, typically dome-shaped and rising several hundreds of metres above the surrounding ice shelf . An ice rise forms where the ice shelf touches the seabed due to a locally increased elevation of the seabed, which however remains below sea level. (In contrast, an elevation in the seabed that extends above sea level is defined as an island). The ice shelf flows over the seabed elevation, completely covering it with ice, thereby forming an ice rise. The resulting stress increases cause crevasse formation around the ice rise. An island within and totally covered by the ice shelf may appear the same as an ice rise. Elaborate measurements may be required to distinguish between these two geographic features. Although ice rises are typically located within the ice shelf area, they can partially face the open sea. At present, ice rises are found only within the ice shelves of Antarctica.

Larsen Ice Shelf
The Larsen Ice Shelf is a long ice shelf in the northwest part of the Weddell Sea, extending along the east coast of the Antarctic Peninsula from Cape Longing to Smith Peninsula. It is named after Captain Carl Anton Larsen, the master of the Norwegian whaling vessel ''Jason'', who sailed along the ice front as far as 68°10' South during December 1893. In finer detail, the Larsen Ice Shelf is a series of shelves that occupy (or occupied) distinct embayments along the coast. From north to south, the segments are called Larsen A (the smallest), Larsen B, and Larsen C (the largest) by researchers who work in the area. Further south, Larsen D and the much smaller Larsen E, F and G are also named. The breakup of the ice shelf since the mid-1990s has been widely reported, with the collapse of Larsen B in 2002 being particularly dramatic. A large section of the Larsen C shelf broke away in July 2017 to form an iceberg known as A-68. The ice shelf originally covered an area of , but ...

Hearst Island
Hearst Island is an ice-covered, dome-shaped island lying east of Cape Rymill, in the Weddell Sea, off the eastern coast of Palmer Land. The island is long, in a north–south direction, wide, and rises to . It was first sighted on a flight on December 20, 1928, by Sir Hubert Wilkins. Thinking it was part of the mainland of Antarctica, he named it Hearst Land, for William Randolph Hearst who helped finance the expedition. It was resighted and its insularity ascertained in 1940 by members of the USAS who explored this coast by land and from the air. They named it Wilkins Island. Examination of aerial photographs have shown, however, that this large island is what Wilkins considered Hearst Land.

Super Constellation
The Lockheed L-1049 Super Constellation is an American aircraft, a member of the Lockheed Constellation aircraft line. The L-1049 was Lockheed's response to the successful Douglas DC-6 airliner, first flying in 1950. The aircraft was also produced for both the United States Navy as the WV / R7V and U.S. Air Force as the C-121 for transport, electronics, and airborne early warning and control aircraft. Development Beginning in 1943, Lockheed planned stretched variants of the Constellation family. The first was the L-049 with a fuselage lengthened by 13 feet (4 meters) and the second the L-749 stretched 18 feet (5.5 meters). Douglas launched a stretched version of its DC-6 airliner as a cargo transport, designated DC-6A, for both military and civilian operators. Douglas was soon to launch a passenger version (the DC-6B) of this new aircraft. The DC-6B could carry 23 more passengers than Lockheed's current production L-749 Constellation. In 1950, Lockheed had repurchased the X ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Derek R
Derek is a masculine given name. It is the English language short form of ''Diederik'', the Low Franconian form of the name Theodoric. Theodoric is an old Germanic name with an original meaning of "people-ruler". Common variants of the name are Derrek, Derick, Dereck, Derrick, and Deric. Low German and Dutch short forms of Diederik are Dik, Dirck, and Dirk. History The English form of the name arises in the 15th century, via import from the Low Countries. The native English (Anglo-Saxon) form of the name was ''Deoric'' or ''Deodric'', from Old English ''Þēodrīc'', but this name had fallen out of use in the medieval period. During the Late Middle Ages, there was intense contact between the territories adjacent to the North Sea, in particular due to the activities of the Hanseatic League. As a result, there was a lot of cross-pollination between Low German, Dutch, English, Danish and Norwegian. The given name ''Derk'' is found in records of the Low Countries from the early 1 ...

Ice Rises Of Antarctica
Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on its his ...
