Cape Sibbald
Cape Sibbald () is a cliffed cape at the southwest margin of Lady Newnes Bay on the coast of Victoria Land. It marks the southwest extremity of the Mountaineer Range at the terminus of Aviator Glacier. Sighted in February 1841 by Sir James Clark Ross and named by him for Lieutenant (later Cdr.) John Sibbald Sir John Sibbald FRSE FBSE (24 June 1833 – 20 April 1905) was a 19th-century Scottish physician and amateur botanist.

Cliffed Coast
A cliffed coast, also called an abrasion coast, is a form of coast where the action of marine waves has formed steep cliffs that may or may not be precipitous. It contrasts with a flat or alluvial coast. Formation In coastal areas in which the land surface dips at a relatively steep angle below the water table, the continuous action of marine waves on the coastline, known as abrasion, may create a steep declivity known as a cliff, the slope angle of which depends on a variety of factors including the jointing, bedding and hardness of the materials making up the cliff as well as the erosional processes themselves.Herbert Louis and Klaus Fischer: ''Allgemeine Geomorphologie'', de Gruyter, 4th ed., Berlin 1979, pp. 532-537 The slope is constantly being eroded. The waves attacking the cliff-foot form a wave-cut notch by constant abrasion action producing an overhang. This overhang grows in size as the cliff is undercut, until it collapses under its own weight. The loose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lady Newnes Bay
Lady Newnes Bay is a bay about 60 mi long in the western Ross Sea, extending along the coast of Victoria Land from Cape Sibbald to Coulman Island. Discovered by the British Antarctic Expedition, 1898–1900, led by Carstens Borchgrevink. He named it for Lady Priscilla Newnes, whose husband, Sir George Newnes, financed the expedition. Falkner Glacier forms a glacier tongue An ice tongue is a long and narrow sheet of ice projecting out from the coastline. An ice tongue forms when a valley glacier moves very rapidly (relative to surrounding ice) out into the ocean or a lake. They can gain mass from water freezing at t ... in the bay.

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountaineer Range
Mountaineer Range is the range of mountains lying between the Mariner and Aviator Glaciers in Victoria Land, Antarctica. The seaward parts of the range were first viewed by Ross in 1841, and subsequently by several British and later American expeditions. The precise mapping of its overall features was accomplished from U.S. Navy air photographs and surveys by New Zealand and American parties in the 1950s and 1960s. Named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, in keeping with the backgrounds of members of the 1957–58 and 1958–59 field parties who made a reconnaissance of the area, and also in association with the names "Aviator" and "Mariner". The highest point is Mount Murchison, at , on the rugged divide between the Fitzgerald and Wylde Glaciers. Discovered in January 1841 by Ross who named this feature for Sir Roderick Impey Murchison, then general secretary of the British Association. List of mountains * Mount Murchiso ...

Aviator Glacier
Aviator Glacier is a major valley glacier in Antarctica that is over long and wide, descending generally southward from the plateau of Victoria Land along the west side of Mountaineer Range, and entering Lady Newnes Bay between Cape Sibbald and Hayes Head where it forms the Aviator Glacier Tongue. A glacier is a mass of ice with sufficient thickness to flow away from the source area in lobes, tongues or masses. Glaciers are usually found at high latitudes or high elevations. The glacier was photographed from the air by Captain W.M. Hawkes, US Navy, on the historic first flight from New Zealand to McMurdo Sound on December 17, 1955. An attempt to reconnoiter it by helicopter and to land a party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE) on it had to be abandoned when USS ''Glacier'' was damaged in pressure ice in December 1958. It was named by NZGSAE, 1958–59, as a tribute to the hazardous work of pilots and other airmen in Antarctic exploratory and ...

Sir James Clark Ross
Sir James Clark Ross (15 April 1800 – 3 April 1862) was a British Royal Navy officer and polar explorer known for his explorations of the Arctic, participating in two expeditions led by his uncle John Ross, and four led by William Edward Parry, and, in particular, for his own Antarctic expedition from 1839 to 1843. Biography Early life Ross was born in London, the son of George Ross and nephew of John Ross, under whom he entered the Royal Navy on 5 April 1812. Ross was an active participant in the Napoleonic Wars, being present at an action where HMS ''Briseis'', commanded by his uncle, captured ''Le Petit Poucet'' (a French privateer) on 9 October 1812. Ross then served successively with his uncle on HMS ''Actaeon'' and HMS ''Driver''. Arctic exploration Ross participated in John's unsuccessful first Arctic voyage in search of a Northwest Passage in 1818 aboard ''Isabella''. Between 1819 and 1827 Ross took part in four Arctic expeditions under William Ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Sibbald
Sir John Sibbald FRSE FBSE (24 June 1833 – 20 April 1905) was a 19th-century Scottish physician and amateur botanist. In 1855/56, aged 22, he served as president of the Royal Medical Society.

Headlands Of Victoria Land
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
