Névé
Névé is a young, granular type of snow which has been partially melted, refrozen and compacted, yet precedes the form of ice. This type of snow is associated with glacier formation through the process of ''nivation''. Névé that survives a full season of ablation turns into firn, which is both older and slightly denser. Firn eventually becomes glacial ice – the long-lived, compacted ice that glaciers are composed of. Glacier formation can take days to years depending on freeze-thaw factors. Névé is annually observed in skiing slopes, and is generally disliked as an icy falling zone. Névé has a minimum density of 500 kg/m3, which is roughly half of the density of liquid water at 1 atm. Névé can also refer to the alpine Alpine may refer to any mountainous region.

Koettlitz Glacier
Koettlitz Glacier is a large Antarctic glacier lying west of Mount Morning and Mount Discovery in the Royal Society Range, flowing from the vicinity of Mount Cocks northeastward between Brown Peninsula and the mainland into the ice shelf of McMurdo Sound. It was discovered by the British National Antarctic Expedition (1901–04) which named it for Dr. Reginald Koettlitz, physician and botanist of the expedition.

This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice.

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] |

Mount Morning
Mount Morning is a shield volcano at the foot of the Transantarctic Mountains in Victoria Land, Antarctica. It lies from Ross Island. Mount Morning rises to an elevation of and is almost entirely mantled with snow and ice. A wide summit caldera lies at the top of the volcano and several ice-free ridges such as Hurricane Ridge and Riviera Ridge emanate from the summit. A number of parasitic vents mainly in the form of cinder cones dot the mountain. The volcano was initially active during the Miocene and erupted in two separate stages with a hiatus in between. The older stage has a different chemical composition than the recent one and is heavily eroded by glaciers. The most recent parasitic vents were active about 20,000 years ago and the volcano could erupt again. Geography and geomorphology Mount Morning lies in Victoria Land, about from Ross Island and at the foot of the Transantarctic Mountains. The Koettlitz Glacier runs along the northwestern foot of Mount Morning an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Fields Of The Ross Dependency
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or Sublimation (phase transition), sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes Nucleation, nucleate around particles in the atmosphere by attracting supercooling, supercooled water droplets, which Freezing, freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and Hard rime, rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamo ... [...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, plateaux, and plains are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scott Coast
Scott Coast () is the portion of the coast of Victoria Land, Antarctica between Cape Washington and Minna Bluff. It was named by the New Zealand Antarctic Place-Names Committee in 1961 after Captain Robert Falcon Scott, Royal Navy, leader of the ''Discovery'' Expedition (1901–1904) and the British Antarctic Expedition (1910-1913), who died on the return journey from the South Pole. Much of the early exploration of this coastline was accomplished by Scott and his colleagues, and many of the names in the region were bestowed by him.
