Venture Dome
Venture Dome () is a large, heavily crevassed ice dome about 30 nautical miles (60 km) south of Mount Twintop in Mac. Robertson Land. The feature had been seen by several parties traveling south from Mawson Station since 1957, but it had been avoided. In 1967, ANARE (Australian National Antarctic Research Expeditions The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involv ...) surveyor J. Manning selected a route through the crevasses and established a beaconed tellurometer station on it. So named by ANARE to indicate the risk taken in crossing the dome. Ice caps of Antarctica Bodies of ice of Mac. Robertson Land {{MacRobertsonLand-geo-stub ...

Ice Cap
In glaciology, an ice cap is a mass of ice that covers less than of land area (usually covering a highland area). Larger ice masses covering more than are termed ice sheets. Description Ice caps are not constrained by topographical features (i.e., they will lie over the top of mountains). By contrast, ice masses of similar size that ''are'' constrained by topographical features are known as ice fields. The ''dome'' of an ice cap is usually centred on the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery. Ice caps have significant effects on the geomorphology of the area that they occupy. Plastic moulding, gouging and other glacial erosional features become present upon the glacier's retreat. Many lakes, such as the Great Lakes in North America, as well as numerous valleys have been formed by glacial action over hundreds of thousands of years. On Earth, there are about of total ice mass.

Mount Twintop
Mount Twintop () is a twin-peaked mountain about 6 nautical miles (11 km) south-southwest of Mount Tritoppen in the south part of the David Range, Framnes Mountains. Immediately north of Mount Twintop are the Butler Nunataks, and Venture Dome lies 60 km to the south. Mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition (1936–37) and named Tvitoppen (the twin peak). The translated form of the name recommended by Antarctic Names Committee of Australia The Australian Antarctic Names and Medals Committee (AANMC) was established to advise the Government on names for features in the Australian Antarctic Territory and the subantarctic territory of Heard Island and the McDonald Islands. The committee ... (ANCA) has been adopted. See also *List of mountains of East Antarctica Mountains of Mac. Robertson Land {{MacRobertsonLand-geo-stub ...

Mawson Station
The Mawson Station, commonly called Mawson, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Mawson lies in Holme Bay in Mac. Robertson Land, East Antarctica in the Australian Antarctic Territory, a territory claimed by Australia. Established in 1954, Mawson is Australia's oldest Antarctic station and the oldest continuously inhabited Antarctic station south of the Antarctic Circle. Mawson was named in honour of the Australian Antarctic explorer Sir Douglas Mawson. Mawson was listed on the Register of the National Estate in 2001 and listed on the Commonwealth Heritage List on 22 June 2004, reflecting the post-World War Two revival of Australia's scientific research and territorial interests in Antarctica. Purpose Mawson Station is a base for scientific research programs including an underground cosmic ray detector, various long-term meteorological aeronomy and geomagnetic studies, as well as ongoing cons ...

Australian National Antarctic Research Expeditions
The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involvement in south polar regions since as early as Douglas Mawson's Australasian Antarctic Expedition in 1911. Further Australian exploration of the Antarctic continent was conducted during the British Australian and New Zealand Antarctic Research Expedition (BANZARE), which was conducted over the years 1929–1931. The Australian National Antarctic Research Expeditions were established in 1947 with expeditions to Macquarie Island and Heard Island. In 1948 the Australian Antarctic Division (AAD) was established to administer the expedition program. ANARE Name The name ANARE fell out of official use in the early 2000s. However current and former Australian Antarctic expeditioners continue to use the term informally as a means of identifica ...

Ice Caps Of Antarctica
Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
