Marguerite Bay
Marguerite Bay or Margaret Bay is an extensive bay on the west side of the Antarctic Peninsula, which is bounded on the north by Adelaide Island and on the south by Wordie Ice Shelf, George VI Sound and Alexander Island. The mainland coast on the Antarctic Peninsula is Fallières Coast. Islands within the bay include Pourquoi Pas Island, Horseshoe Island, Terminal Island, and Lagotellerie Island. Marguerite Bay was discovered in 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot, who named the bay for his wife. Named features Toadstool Rocks are a group of insular, ice-covered rocks that rise to about 250 cm above sea level in the southwest part of Marguerite Bay, east-southeast of Terminal Island. The rocks were roughly charted from RRS association with Mushroom Island and Puffball Islands. Endurance Reef is a reef in Marguerite Bay, lying west of Red Rock Ridge. The name is after HMS ''Endurance'' which at this position in February 1972 str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martin in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about away across the Drake Passage. The Antarctic Peninsula is in area and 80% ice-covered. The marine ecosystem around the western continental shelf of the Antarctic Peninsula (WAP) has been subjected to rapid Climate change in Antarctica, clima ...

Reef
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 component, abiotic (non-living) processes such as deposition (geology), deposition of sand or wave erosion planning down rock outcrops. However, reefs such as the coral reefs of tropical waters are formed by biotic component, 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 n ...

Bays Of Graham Land
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a ''gulf'', ''sea'', ''sound'', or ''bight''. A ''cove'' is a small, circular bay with a narrow entrance. A ''fjord'' is an elongated bay formed by glacial action. The term ''embayment'' is also used for , such as extinct bays or freshwater environments. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore wit ...

Emperor Island
Emperor Island is a small island in Marguerite Bay, lying close north-east of the Courtier Islands in the Dion Islands. The islands in this group were discovered and roughly charted in 1909 by the French Antarctic Expedition. This island was surveyed in 1948 by the Falkland Islands Dependencies Survey and so named by the UK Antarctic Place-Names Committee because a low rock and shingle isthmus at the south-eastern end of the island was the winter breeding site of emperor penguins. Important Bird Area A 467 ha site, coinciding with that of Antarctic Specially Protected Area (ASPA) No.107, has been designated an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of Antarctic shags. It is likely that emperor penguins no longer breed on the island.

United Kingdom 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 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.

Dion Islands
The Dion Islands are a group of small islands and rocks lying in the northern part of Marguerite Bay, south-west of Cape Alexandra, Adelaide Island, off the west coast of the Antarctic Peninsula. They were discovered by the French Antarctic Expedition, 1908–10, and named by Jean-Baptiste Charcot for the Marquis Jules-Albert de Dion, who donated three motor sledges and whose De Dion-Bouton works produced equipment for the expedition. It is also the site of a memorial of three lost men from the British Antarctic Syrvey who died in 1958 after a fierce storm drifted the men on the ice they were camped on drifted out to open sea. Important Bird Area The islands have been identified as an Important Bird Area (IBA) by BirdLife International because they support a breeding colony of about 500 pairs of imperial shags. There is also a small colony of about 150 pairs of emperor penguins, the second-most northerly known of this species (the most northerly being Snow Hill Island) and o ...

Brian E
Brian (sometimes spelled Bryan in English) is a male given name of Irish and Breton origin, as well as a surname of Occitan origin. It is common in the English-speaking world. It is possible that the name is derived from an Old Celtic word meaning "high" or "noble". For example, the element ''bre'' means "hill"; which could be transferred to mean "eminence" or "exalted one". The name is quite popular in Ireland, on account of Brian Boru, a 10th-century High King of Ireland. The name was also quite popular in East Anglia during the Middle Ages. This is because the name was introduced to England by Bretons following the Norman Conquest. Bretons also settled in Ireland along with the Normans in the 12th century, and 'their' name was mingled with the 'Irish' version. Also, in the north-west of England, the 'Irish' name was introduced by Scandinavian settlers from Ireland. Within the Gaelic-speaking areas of Scotland, the name was at first only used by professional families of Irish ... [...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 to 1956. 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.

Northstar Island (Antarctica)
Northstar Island is a artificial island in the Beaufort Sea, northwest of Prudhoe Bay, Alaska and north of the Alaska coast.Alaska Oil and Gas Conservation Commission"Northstar Unit, Northstar Oil Pool" State of Alaska. July 25, 2005. Accessed July 29, 2009. The island was created to develop the Northstar Oil Pool, which is located approximately below the seabed. The oil pool was discovered on January 30, 1984 by Royal Dutch Shell. A small artificial island was built at the site to house an exploration oil well. After additional exploration, Alaska International Construction began construction of the island in the winter of 1999–2000. A standard oil-drilling platform, such as those used in the Gulf of Mexico, was not feasible because of the annual formation of pack ice close to the northern Alaska coast. A stable, year-round artificial island was the only way to provide the permanent structures needed for a production oil well. To protect against the erosive force of ma ...

Miller Island (Antarctica)
Hart Miller Island is located at the mouths of Back River and Middle River, where they empty into the Chesapeake Bay east of the City of Baltimore in Maryland. It was formerly two separate islands, Hart Island and Miller Island, but it is now almost entirely artificial. In 1981, the area began being filled with dredged material by the U.S. Army Corps of Engineers, for the purpose of habitat restoration Ecological restoration, or ecosystem restoration, is the process of assisting the recovery of an ecosystem that has been degraded, damaged, destroyed or transformed. It is distinct from conservation in that it attempts to retroactively repair ..., and the project was completed in 2012. It is now in use as Hart-Miller Island State Park, accessible only by boat.
