Murray Glacier
Murray Glacier () is a valley glacier, long, draining seaward along the east side of Geikie Ridge in the Admiralty Mountains. Its terminus coalesces with that of Dugdale Glacier where both glaciers discharge into Robertson Bay along the north coast of Victoria Land. First charted by the British Antarctic Expedition 1898-1900, under Carsten Borchgrevink, who named this feature for Sir John Murray of the Challenger Expedition The ''Challenger'' expedition of 1872–1876 was a scientific program that made many discoveries to lay the foundation of oceanography. The expedition was named after the naval vessel that undertook the trip, . The expedition, initiated by W ..., 1872–76. References Glaciers of Pennell Coast {{PennellCoast-glacier-stub ...

Valley
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. For ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geikie Ridge
Robertson Bay is a large, roughly triangular bay that indents the north coast of Victoria Land between Cape Barrow and Cape Adare.

Admiralty Mountains
The Admiralty Mountains (alternatively Admiralty Range) is a large group of high mountains and individually named ranges and ridges in northeastern Victoria Land, Antarctica. This mountain group is bounded by the Ross Sea, the Southern Ocean, and by the Dennistoun, Ebbe, and Tucker glaciers. The mountain range is situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare. It was discovered in January 1841 by Captain James Ross, who named them for the Lords Commissioners of the Admiralty under whose orders he served. The Admiralty Mountains are divided into the Dunedin Range, Homerun Range, and Lyttelton Range. Mountains and peaks This range includes the following mountains and peaks: Mount Achilles Mount Achilles is a prominent pyramidal mountain rising from the divide between Fitch Glacier and Man-o-War Glacier.

Dugdale Glacier
Dugdale Glacier () is a glacier about long, draining northeast from the Admiralty Mountains into Robertson Bay on the north coast of Victoria Land, Antarctica. The geographical feature flows along the west side of Geikie Ridge before coalescing with Murray Glacier just west of Duke of York Island. It was charted by the British Antarctic Expedition, 1898–1900, under Carsten Borchgrevink, who named it for Frank Dugdale of Snitterfield, Stratford-on-Avon. The glacier lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams Cape Williams () is an ice-covered cape in Antarctica. It is the termination of Buell Peninsula at the east side of the terminus of Lillie Glacier at the lower ends of George Glacier and Zykov Glacier.

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 A meteorite is a solid piece of debris from an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Cross Expedition
The ''Southern Cross'' Expedition, otherwise known as the British Antarctic Expedition, 1898–1900, was the first British venture of the Heroic Age of Antarctic Exploration, and the forerunner of the more celebrated journeys of Robert Falcon Scott and Ernest Shackleton. The brainchild of the Anglo-Norwegian explorer Carsten Borchgrevink, it was the first expedition to over-winter on the Antarctic mainland, the first to visit the Great Ice Barrier—later known as the Ross Ice Shelf—since Sir James Clark Ross's groundbreaking expedition of 1839 to 1843, and the first to effect a landing on the Barrier's surface. It also pioneered the use of dogs and sledges in Antarctic travel. The expedition was privately financed by the British magazine publisher Sir George Newnes. Borchgrevink's party sailed in the , and spent the southern winter of 1899 at Cape Adare, the northwest extremity of the Ross Sea coastline. Here they carried out an extensive programme of scientific observations, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carsten Borchgrevink
Carsten Egeberg Borchgrevink (1 December 186421 April 1934) was an Anglo-Norwegian polar explorer and a pioneer of Antarctic travel. He inspired Sir Robert Falcon Scott, Sir Ernest Shackleton, Roald Amundsen, and others associated with the Heroic Age of Antarctic Exploration. Borchgrevink began his exploring career in 1894 by joining a Norwegian whaling expedition, during which he became one of the first people to set foot on the Antarctic mainland. This achievement helped him to obtain backing for his ''Southern Cross'' expedition, which became the first to overwinter on the Antarctic mainland, and the first to visit the Great Ice Barrier since the expedition of Sir James Clark Ross nearly sixty years earlier. The expedition's successes were received with only moderate interest by the publicand by the British geographical establishment, whose attention was by then focused on Scott's upcoming ''Discovery'' expedition. Some of Borchgrevink's colleagues were critical of his le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Murray (oceanographer)
Sir John Murray (3 March 1841 – 16 March 1914) was a pioneering Canadian-born British oceanographer Oceanography (), also known as oceanology and ocean science, is the scientific study of the oceans. It is an Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics ..., marine biologist and limnologist. He is considered to be the father of modern oceanography. Early life and education Murray was born at Cobourg, Ontario, Cobourg, Canada West (now Ontario) on 3 March 1841. He was the second son of Robert Murray, an accountant, and his wife Elizabeth Macfarlane. His parents had emigrated from Scotland to Ontario in about 1834. He went to school in London, Ontario and later to Cobourg College. In 1858, at the age of 17 he returned to Scotland to live with his grandfather, John Macfarlane, and continue his education at Stirling High School. In 1864 he enrolled at University of Edinburgh to study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
