Lyddan Island
Lyddan Island is an ice-covered island located at the southwestern extremity of the Riiser-Larsen Ice Shelf, separating it from the Brunt Ice Shelf, about off the Princess Martha Coast of Antarctica. It is about long and has three narrow arms in the form of a trefoil. It was discovered and plotted by W.R. MacDonald on November 5, 1967, in the course of a U.S. Navy Squadron VXE-6 reconnaissance flight over the coast in LC-130 aircraft, and was named by the Advisory Committee on Antarctic Names for Robert H. Lyddan, Chief Topographic Engineer of the United States Geological Survey, who had been active in the planning and supervision of Antarctic mapping operations since the 1950s. Though originally recorded as an island, later research has shown that the ground surface under the ice is below sea level, indicating that "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 a ...

Riiser-Larsen Ice Shelf
Riiser-Larsen Ice Shelf is an ice shelf about 250 miles (400 km) long on the coast of Queen Maud Land, Antarctica, extending from Cape Norvegia in the north to Lyddan Island and Stancomb-Wills Glacier in the south. Discovery and naming Parts of the ice shelf were sighted by William Speirs Bruce in 1904, Ernest Shackleton in 1915, and Hjalmar Riiser-Larsen in 1930. Most of it was photographed from the air in 1951-52 by the Norwegian-British-Swedish Antarctic Expedition (NBSAE) and delineated from these photos. Additional delineation of the southern and landward margins of the feature was accomplished from aerial photos taken, by the USN's Operation Deep Freeze from 1967 to 1969. The feature was named by Norway for Captain Hjalmar Riiser-Larsen, who explored the area in the late 1920s and early 1930s. Important Bird Area A 477 ha site on fast ice, on the northern coast of the ice shelf some 90 km south-west of Seal Bay and 140 km north-east of Cape Vest ...

Brunt Ice Shelf
The Brunt Ice Shelf borders the Antarctic coast of Coats Land between Dawson-Lambton Glacier and Stancomb-Wills Glacier Tongue. It was named by the UK Antarctic Place-names Committee after David Brunt, British meteorologist, Physical Secretary of the Royal Society, 1948–57, who was responsible for the initiation of the Royal Society Expedition to this ice shelf in 1955. It was the location of the base of the Royal Society Expedition, 1955–59 which was taken over as the British Halley Research Station. The Brunt Icefalls () extend along Caird Coast for about , where the steep ice-covered coast descends to Brunt Ice Shelf. The icefalls were discovered on 5 November 1967, in the course of a United States Navy Squadron VXE-6 flight over the coast in LC-130 aircraft, and was plotted by the United States Geological Survey from air photos obtained at that time. It was named by the Advisory Committee on Antarctic Names in association with the Brunt Ice Shelf. In 2012 previously ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Princess Martha Coast
Princess Martha Coast ( no, Kronprinsesse Märtha Kyst) is that portion of the coast of Queen Maud Land lying between 05° E and the terminus of Stancomb-Wills Glacier, at 20° W. The entire coastline is bounded by ice shelves with ice cliffs high. Princess Martha Coast was the first portion of Antarctic mainland discovered by a human, Fabian von Bellingshausen and Mikhail Lazarev in 1820. The name "Crown Princess Martha Land" was originally applied by Capt. Hjalmar Riiser-Larsen to that section of the coast in the vicinity of Cape Norvegia which he discovered from the ''Norvegia'' and roughly charted from the air during February 1930. On January 19, 1939, Nazi Germany reached the Martha Coast which was a part of the German Antarctic Expedition. It is named in honour of Crown Princess Märtha of Norway. Troll is located in the eastern part, from the coast. Explora Escarpment Explora Escarpment () is an undersea escarpment named for the Antarctic science ship ''F.S. E ...

VXE-6
Antarctic Development Squadron Six (VXE-6 or ANTARCTIC DEVRON SIX, commonly referred to by its nickname, The Puckered Penguins) was a United States Navy air test and evaluation squadron based at Naval Air Station Point Mugu, California with forward operating bases at Christchurch, New Zealand and McMurdo Station, Antarctica. Established at Naval Air Station Patuxent River, Maryland on 17 January 1955 as Air Development Squadron Six (VX-6), the squadron's mission was to conduct operations in support of Operation Deep Freeze, the operational component of the United States Antarctic Program. The squadron relocated to Naval Air Station Quonset Point, Rhode Island on 1 February 1956. On 1 January 1969 the squadron was redesignated Antarctic Development Squadron Six (VXE-6). Following the closure of NAS Quonset Point in the 1970s, the squadron relocated to NAS Point Mugu. Using the tail codes ''XD'' (1955) and ''JD'' (1957), the squadron flew numerous aircraft over the course of its e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LC-130
The Lockheed LC-130 is a ski-equipped United States Air Force variant of the C-130 Hercules used in the Arctic and Antarctic. Ten are currently in service with the 109th Airlift Wing of the New York Air National Guard. Design and development The LC-130 started as a prototype model developed by modifying a ''C-130A'' with skis in 1956. After testing in 1957, 12 additional C-130A models were modified with skis and hydraulics under the designation of ''C-130D''. In 1959 the first four factory equipped, ski-based Hercules were produced under the Navy designation of UV-1L. These C-130s are USAF C-130B models. Later in the program the designation was changed from UV-1L to C-130BL. This designation was again later changed to LC-130F when aircraft nomenclature was standardized for all services by the U. S. Defense Department in 1962. These four aircraft were bought by the Navy Department to support the Navy's Antarctic expedition that was ongoing at the time. The Navy also bought one ...

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 in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert H
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

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.
