Normanna Reef
Normanna Reef () is a reef lying near the center of the south entrance to the sound in the Melchior Islands The Melchior Islands are a group of many low, ice-covered islands lying near the center of Dallmann Bay between Brabant Island and Anvers Island in the Palmer Archipelago, Antarctica.

Melchior Islands
The Melchior Islands are a group of many low, ice-covered islands lying near the center of Dallmann Bay between Brabant Island and Anvers Island 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 (Palmer Archipelago), 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 personne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Discovery Investigations contributed greatly to knowledge of the whales, the krill they fed on and their habitat's oceanography, while charting the local topography, including Atherton Peak. They continued until 1951, with the final report published in 1980. Collected specimens are in the Discovery Collections.Skinner, L.

Reefs Of Graham Land
A reef is a ridge or shoal of rock, coral, or similar relatively stable material lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic (non-living) processes such as deposition of sand or wave erosion planning down rock outcrops. However, reefs such as the coral reefs of tropical waters are formed by biotic (living) processes, dominated by corals and coralline algae. Artificial reefs, such as shipwrecks and other man-made underwater structures, may occur intentionally or as the result of an accident. These are sometimes designed to increase the physical complexity of featureless sand bottoms to attract a more diverse range of organisms. They provide shelter to various aquatic animals which help prevent extinction. Another reason reefs are put in place is for aquaculture, and fish farmers who are looking to improve their businesses sometimes invest in them. Reefs are often quite near to the surface, but not all definitions require th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
