Melchior Islands
The Melchior Islands are a group of many low, ice-covered islands lying near the center of Dallmann Bay in the Palmer Archipelago, Antarctica. They were first seen but left unnamed by a German expedition under Eduard Dallmann, 1873–74. The islands were resighted and roughly charted by the Third French Antarctic Expedition under Jean-Baptiste Charcot, 1903–05. Charcot named what he believed to be the large easternmost island in the group "Île Melchior" after Vice Admiral Jules Melchior of the French Navy, but later surveys proved Charcot's Île Melchior to be two islands, now called Eta Island and Omega Island. The name Melchior Islands has since become established for the whole island group now described, of which Eta Island and Omega Island form the eastern part, while the Sigma Islands mark the northern limit of the islands. The group was roughly surveyed in 1927 by Discovery Investigations personnel in the ''RRS Discovery'', and was resurveyed by Argentine expeditio ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha Island
Alpha Island, also known as Isla Huidobro, is a small island lying between Epsilon Island and Delta Island in the Melchior Islands, Palmer Archipelago. Charted by Discovery Investigations in 1927 and named after the first letter of the Greek alphabet, in association with the names of other islands in this group. The island was surveyed by Argentine expeditions in 1942, 1943 and 1948.

Scientific Committee On Antarctic Research
The Scientific Committee on Antarctic Research (SCAR) is an interdisciplinary body of the International Science Council (ISC). SCAR coordinates international scientific research efforts in Antarctica, including the Southern Ocean. SCAR's scientific work is administered through several discipline-themed ''science groups''. The organisation has observer status at, and provides independent advice to Antarctic Treaty Consultative Meetings, and also provides information to other international bodies such as the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Framework Convention on Climate Change (UNFCCC). History At the International Council of Scientific Unions (ICSU)’s Antarctic meeting held in Stockholm from 9–11 September 1957, it was agreed that a committee should be created to oversee scientific research in Antarctica. At the time there were 12 nations actively conducting Antarctic research and they were each invited to nominate one delegate to ...

Composite Antarctic Gazetteer
The Composite Gazetteer of Antarctica (CGA) of the Scientific Committee on Antarctic Research (SCAR) is the authoritative international gazetteer containing all Antarctic toponyms published in national gazetteers, plus basic information about those names and the relevant geographical features. The Gazetteer includes also parts of the International Hydrographic Organization (IHO) General Bathymetric Chart of the Oceans (GEBCO) gazetteer for under-sea features situated south of 60° south latitude. , the overall content of the CGA amounts to 37,893 geographic names for 19,803 features including some 500 features with two or more entirely different names, contributed by the following sources: {, class="wikitable sortable" !

Gerlache Strait
Gerlache Strait or de Gerlache Strait or Détroit de la Belgica is a Channel (geography), channel/strait separating the Palmer Archipelago from the Antarctic Peninsula. The Belgian Antarctic Expedition, under Lt. Adrien de Gerlache, explored the strait in January and February 1898, naming it for the expedition ship ''RV Belgica (1884), Belgica''. The name was later changed to honor the commander himself. On the expedition in the Gerlache Strait, biologist Emil Racoviță made several discoveries, including a flightless midge fly that was later formally named ''Belgica antarctica'' by the Belgian Entomology, entomologist Jean-Charles Jacobs. Geology Four tectonic blocks are identifiable in the Gerlache Strait area, bounded by two systems of Tertiary strike-slip faults. The longitudinal faults include the SW-NE trending Neumayer Fault that extends from Peltier Channel across Wiencke Island, and then onwards most likely as the Gerlache Fault. The SW-NE trending Fournier Fault paral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anvers Island
Anvers Island or Antwerp Island or Antwerpen Island or Isla Amberes is a high, mountainous island long, the largest in the Palmer Archipelago of Antarctica. It was discovered by John Biscoe in 1832 and named in 1898 by the Belgian Antarctic Expedition under Adrien de Gerlache after the province of Antwerp in Belgium. It lies south-west of Brabant Island at the south-western end of the group. The south-western coastline of the island forms part of the Southwest Anvers Island and Palmer Basin Antarctic Specially Managed Area (ASMA 7). Cormorant Island, an Important Bird Area, lies 1 km off the south coast. Palmer Station The Palmer Station on Anvers Island is located at () and is Antarctica's only U.S. station north of the Antarctic Circle. Construction finished in 1968. Around 50 people can inhabit Palmer Station at one time. The station is named for Nathaniel B. Palmer, likely to have been one of the first three persons to see Antarctica.

Tripod Island
Tripod Island is a small island which lies close south of the west extremity of Eta Island and marks the north side of the western entrance to Andersen Harbor in the Melchior Islands, Palmer Archipelago.

Psi Islands is a group of small islands which lie close to the west side of Lambda Island in the Melchior Islands, Palmer Archipelago.
