Enigma Peak
Enigma Peak is a peak, high, surmounting Fournier Ridge in the Desko Mountains, on Rothschild Island. It was probably seen from a distance by F. Bellingshausen in 1821, Jean-Baptiste Charcot in 1909, and the British Graham Land Expedition in 1936. It was observed and photographed from the air by the U.S. Antarctic Service, 1939–41, and was mapped as the prominent northwestern peak of the island. It was mapped in greater detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falklands Islands Dependencies Survey in 1960, and from U.S. Landsat imagery of February 1975. It was so named by the UK Antarctic Place-Names Committee The 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 ... because of difficulty in identifying the peak during the ma ...

Desko Mountains
The Desko Mountains are a west-northwest–east-southeast mountain range on Rothschild Island, off northwest Alexander Island. The mountain range spans 20 nautical miles (37 km) from Bates Peak to Overton Peak and rises to about at Enigma Peak, Fournier Ridge. Geographical context Other mountains nearby are Goward Peak, Schenck Peak, Morrill Peak and Thuma Peak. To the east lies Lazarev Bay, a rectangular bay that separates the east side of Rothschild Island from the north-west coast of Alexander Island. Exploration The mountains were seen (in part) from a distance by F. Bellingshausen in 1821, and by Jean-Baptiste Charcot in 1909, but the nature of the feature remained obscure. The Desko mountain range was photographed from the air by U.S. Navy Operation Highjump and the Ronne Antarctic Research Expedition in 1947. The mountain range was further mapped by air by D. Searle of the Falkland Islands Dependencies Survey in 1960. The mountain range was further ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rothschild Island
Rothschild Island is a black rugged island long, mainly ice-covered but surmounted by prominent peaks of Desko Mountains in Antarctica, west of the north part of Alexander Island in the north entrance to Wilkins Sound. History The island was sighted from a distance by the French Antarctic Expedition (c. 1908-1910), and named by Jean-Baptiste Charcot in honor of Édouard Alphonse James de Rothschild (1868-1949), head of the Rothschild banking family of France and president of de Rothschild Frères. In the subsequent explorations of the area by the British Graham Land Expedition (BGLE) (c. 1934-1937), the feature was believed to be a mountain connected to Alexander Island. Geologically this might be true—but it has not been proven by any means due to a lack of anything like a complete geological survey of the region. However, Rothschild Island's insularity was reaffirmed by the United States Antarctic Service (USAS, c. 1939-1941) who photographed and roughly mapped the islan ...

Jean-Baptiste Charcot
Jean-Baptiste-Étienne-Auguste Charcot (15 July 1867 – 16 September 1936), born in Neuilly-sur-Seine, was a French scientist, medical doctor and polar scientist. His father was the neurologist Jean-Martin Charcot (1825–1893). Life Jean-Baptiste Charcot was appointed leader of the French Antarctic Expedition with the ship ''Français'' exploring the west coast of Graham Land from 1904 until 1907. The expedition reached Adelaide Island in 1905 and took pictures of the Palmer Archipelago and Loubet Coast. From 1908 until 1910, another expedition followed with the ship '' Pourquoi Pas ?'', exploring the Bellingshausen Sea and the Amundsen Sea and discovering Loubet Land, Marguerite Bay, Mount Boland and Charcot Island, which was named after his father, Jean-Martin Charcot. anhere./ref> He named Hugo Island after Victor Hugo, the grandfather of his wife, Jeanne Hugo. Later on, Jean-Baptiste Charcot explored Rockall in 1921 and Eastern Greenland and Svalbard from 1925 until 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ronne Antarctic Research Expedition
The Ronne Antarctic Research Expedition (RARE) was an expedition from 1947–1948 which researched the area surrounding the head of the Weddell Sea in Antarctica. Background Finn Ronne led the RARE which was the final privately sponsored expedition from the United States and explored and mapped the last unknown coastline on earth and determined that the Weddell Sea and the Ross Sea were not connected. The expedition included Isaac Schlossbach, as second in command, who was to have Cape Schlossbach named after him. The expedition, based out of Stonington Island was the first to take women to over-winter. Ronne's wife, Edith Ronne was correspondent for the North American Newspaper Alliance for expedition and the chief pilot Darlington took his wife. Partial Listing of Discoveries * Mount Abrams - Named for Talbert Abrams, noted photogrammetric engineer * Mount Becker - Named for Ralph A. Becker, legal counsel who assisted in the formation of RARE * Mount Brundage - Named ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falklands Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

Landsat
The Landsat program is the longest-running enterprise for acquisition of 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. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide (or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UK Antarctic Place-Names Committee
The 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). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by Scientific Committee on Antarctic Research, SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
