David Cauldron
David Cauldron () is an icefall of turbulent iceblocks on the David Glacier, in Victoria Land. It was named by the Southern Party of the New Zealand Geological Survey Antarctic Expedition The New Zealand Geological Survey Antarctic Expedition (NZGSAE) describes a series of scientific explorations of the continent Antarctica. The expeditions were notably active throughout the 1950s and 1960s. Features named by the expeditions 195 ..., 1962–63, in association with David Glacier.

David Glacier
David Glacier is the most imposing outlet glacier in Victoria Land, Antarctica. It is named after the geologist Edgeworth David and is fed by two main flows which drain an area larger than 200,000 square kilometres of the East Antarctic plateau, with an estimated ice discharge rate of 7.8 +/- 0.7 km³/year.Frezzotti,M., A.Capra and L.Vittuari, Ann.Glaciol, v27, 54-60 (1998) The northern flow drains from Talos Dome to the Ross Sea, but the main branch of the stream is fed by a network of tributaries which drain a common area of the inner plateau around Dome C and converge in a spectacular icefall normally known as the David Cauldron.Danesi et al., Earth and Planetary Science Letters, v253, p151-158 (2007) The north wall of David Glacier, near its terminus at Cape Philippi, is named D'Urville Wall after Admiral Jules Dumont d'Urville. As the David Glacier flows into the Ross Sea, it forms a floating mass known as the Drygalski Ice Tongue. Hughes Bluff lies nearby. See al ...

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] |

Landforms Of Victoria Land
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
