George VI SoundGeorge VI Sound or Canal Jorge VI or Canal Presidente Sarmiento or Canal Seaver or King George VI Sound or King George the Sixth Sound is a major bay/faultdepression, 300 miles (483 km) long and mainly covered by a permanent ice shelf. It is in the shape of the letter J without any upper bar.
George VI Ice ShelfThe George VI Ice Shelf (71°45′S68°00′W / 71.750°S 68.000°W / -71.750; -68.000) is an extensive ice shelf that occupies George VI Sound which separates Alexander Island from Palmer Land in Antarctica. The ice shelf extends from Ronne Entrance, at the southwest end of the sound, to Niznik Island, about 30 nautical miles (56 km) south of the north entrance between Cape Brown and Cape Jeremy.Kirwan InletKirwan Inlet (72°21′S 68°50′W) is an inlet in the southeast corner of Alexander Island, 12 nautical miles (22 km) wide at its mouth and indenting 7 nautical miles (13 km), opening on George VI Sound. The inlet is filled with ice and merges almost imperceptibly with the rising ice slopes of Alexander Island to the west.
Alexander IslandAlexander Island, also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.
Royal SocietyBritish learned societyThe Royal Society of London for Improving Natural Knowledge, commonly referred to as the Royal Society, is a learned society and the United Kingdom's national academy of sciences. The society fulfils a number of roles: promoting science and its benefits, recognising excellence in science, supporting outstanding science, providing scientific advice for policy, education and public engagement and fostering international and global co-operation.
Palmer LandPalmer Land (71°30′S065°00′W / 71.500°S 65.000°W / -71.500; -65.000) is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz.
UK Antarctic Place-Names CommitteeThe UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI).David Christie MartinSir David Christie Martin CBE FRSE FCS FRIC FRSA DCL (7 October 1914 – 16 December 1976) was a Scottish-born scientific administrator, holding several senior positions.
Ice riseAn 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).
International Geophysical YearThe International Geophysical Year (IGY; French: Année géophysique internationale), also referred to as the third International Polar Year, was an international scientific project that lasted from 1 July 1957 to 31 December 1958. It marked the end of a long period during the Cold War when scientific interchange between East and West had been seriously interrupted.
Landsat programThe Landsat program is the longest-running enterprise that has acquired satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images.
Goodenough GlacierThe Goodenough Glacier (72°0′S66°40′W / 72.000°S 66.667°W / -72.000; -66.667 (Goodenough Glacier)) is a broad sweeping glacier to the south of the Batterbee Mountains, flowing from the west shore of Palmer Land, Antarctica, into George VI Sound and the George VI Ice Shelf.*As an Amazon Associate I earn from qualifying purchases.
