Lemaire Channel
Lemaire Channel is a strait off Antarctica, between Kyiv Peninsula in the mainland's Graham Land and Booth Island. Nicknamed "Kodak Gap" by some, it is one of the top tourist destinations in Antarctica; steep cliffs hem in the iceberg-filled passage, which is long and just wide at its narrowest point. It was first seen by the German expedition of 1873-74, but not traversed until December 1898, when the ''Belgica'' of the Belgian Antarctic Expedition passed through. Expedition leader Adrien de Gerlache named it for Charles Lemaire (1863-1925), a Belgian explorer of the Congo. The channel has since become a standard part of the itinerary for cruising in Antarctica; not only is it scenic, but the protected waters are usually as still as a lake, a rare occurrence in the storm-wracked southern seas, and the north-south traverse delivers vessels close to Petermann Island for landings. The principal difficulty is that icebergs may fill the channel, especially in early season, ob ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dannebrog Islands
The Dannebrog Islands are a group of islands and rocks lying between the Wauwermans Islands and the Vedel Islands in the Wilhelm Archipelago. The Wilhelm Archipelago was first sighted and named by a German expedition under Eduard Dallmann, 1873–74, and was resighted and the whole archipelago named the Dannebrog Islands by the Belgian Antarctic Expedition, 1897–99, under Gerlache, in appreciation of support given to Gerlache by Denmark. Dallmann's original naming has been retained for the archipelago, and the name Dannebrog restricted to the smaller group here described.

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 ve ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

RRS John Biscoe (1956)
The RRS ''John Biscoe'' was a supply and research vessel used by the British Antarctic Survey between 1956 and 1991. History An earlier vessel, operated from 1947-56. Both were named after the English explorer John Biscoe, who discovered parts of Antarctica in the early 1830s. ''John Biscoe II'' was replaced by in 1991. After decommissioning, she was sold and eventually scrapped in 2004 under the name ''Fayza Express''. Command ''Biscoes first visit to Halley Research Station, in 1959/60 was under the veteran captain, Bill Johnston. From 1975, joint Masters of ''John Biscoe'' were Malcolm Phelps and Chris Elliott. Chris Elliott had joined BAS as Third Officer on ''John Biscoe'' in 1967, becoming Second Officer in 1970.

Depth Sounding
Depth sounding, often simply called sounding, is measuring the depth of a body of water. Data taken from soundings are used in bathymetry to make maps of the floor of a body of water, such as the seabed topography. Soundings were traditionally shown on nautical charts in fathoms and feet. The National Oceanic and Atmospheric Administration (NOAA), the agency responsible for bathymetric data in the United States, still uses fathoms and feet on nautical charts. In other countries, the International System of Units (metres) has become the standard for measuring depth. Terminology "Sounding" derives from the Old English ''sund'', meaning "swimming, water, sea"; it is not related to the word ''sound'' in the sense of noise or tones, but to ''sound'', a geographical term. Traditional terms for soundings are a source for common expressions in the English language, notably "deep six" (a sounding of 6 fathoms). On the Mississippi River in the 1850s, the leadsmen also used old-fash ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
