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.

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] |
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 ...

Palmer Archipelago
Palmer Archipelago, also known as Antarctic Archipelago, Archipiélago Palmer, Antarktiske Arkipel or Palmer Inseln, is a group of islands off the northwestern coast of the Antarctic Peninsula. It extends from Tower Island in the north to Anvers Island in the south. It is separated by the Gerlache and Bismarck straits from the Antarctic Peninsula and Wilhelm Archipelago, respectively. Palmer Archipelago is located at . History Adrien de Gerlache, leader of the Belgian Antarctic Expedition (1897–1899), discovered the archipelago in 1898. He named it Archipelago Palmer for American Captain Nathaniel Palmer, who navigated these waters in 1820.

Island
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epsilon Island (Antarctica)
Epsilon Island in the Antarctic is a small island lying between Alpha Island and the southern extremity of Lambda Island in the Melchior Islands, Palmer Archipelago. The island was roughly surveyed by Discovery Investigations personnel in 1927. The name, derived from epsilon, the fifth letter of the Greek alphabet, appears to have been first used on a 1946 Argentine government chart following surveys of the Melchior Islands by Argentine expeditions in 1942 and 1943.

Delta Island
Delta Island is an island long, lying close southeast of Lambda Island and east of Alpha Island in the Melchior Islands, Palmer Archipelago. The name, derived from the fourth letter of the Greek alphabet, was probably given by Discovery Investigations personnel who roughly surveyed the island in 1927. The island was surveyed by Argentine expeditions in 1942, 1943 and 1948.

Discovery Investigations
The Discovery Investigations were a series of scientific cruises and shore-based investigations into the biology of whales in the Southern Ocean. They were funded by the British Colonial Office and organised by the Discovery Committee in London, which was formed in 1918. They were intended to provide the scientific background to stock management of the commercial Antarctic whale fishery. The work of the Investigations contributed hugely to our knowledge of the whales, the krill they fed on, and the oceanography of their habitat, while charting the local topography, including Atherton Peak. The investigations continued until 1951, with the final report being published in 1980. Laboratory Shore-based work on South Georgia took place in the marine laboratory, Discovery House, built in 1925 at King Edward Point and occupied until 1931. The scientists lived and worked in the building, travelling half a mile or so across King Edward Cove to the whaling station at Grytviken to work on w ...

Greek Alphabet
The Greek alphabet has been used to write the Greek language since the late 9th or early 8th century BCE. It is derived from the earlier Phoenician alphabet, and was the earliest known alphabetic script to have distinct letters for vowels as well as consonants. In Archaic Greece, Archaic and early Classical Greece, Classical times, the Greek alphabet existed in Archaic Greek alphabets, many local variants, but, by the end of the 4th century BCE, the Euclidean alphabet, with 24 letters, ordered from alpha to omega, had become standard and it is this version that is still used for Greek writing today. The letter case, uppercase and lowercase forms of the 24 letters are: : , , , , , , , , , , , , , , , , , /ς, , , , , , . The Greek alphabet is the ancestor of the Latin script, Latin and Cyrillic scripts. Like Latin and Cyrillic, Greek originally had only a single form of each letter; it developed the letter case distinction between uppercase and lowercase in parallel with Latin ...

Argentine
Argentines (mistakenly translated Argentineans in the past; in Spanish (masculine) or (feminine)) are people identified with the country of Argentina. This connection may be residential, legal, historical or cultural. For most Argentines, several (or all) of these connections exist and are collectively the source of their being ''Argentine''. Argentina is a multiethnic and multilingual society, home to people of various ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. As a result, Argentines do not equate their nationality with ethnicity, but with citizenship and allegiance to Argentina. Aside from the indigenous population, nearly all Argentines or their ancestors immigrated within the past five centuries. Among countries in the world that have received the most immigrants in modern history, Argentina, with 6.6 million, ranks second to the United States (27 million), and ahead of other immigr ...
