Una's Peaks
Una Peaks,John Splettstoesser (2009). Una Peaks: a long overdue Antarctic geographical naming. Polar Record, 45, pp 177-179. doi:10.1017/S0032247408008036abstract/ref> formerly known as Cape Renard Towers, are two towers of basalt, each topped by a cap of ice, guarding the northern entrance to the Lemaire Channel on the Antarctic Peninsula. With the highest summit at , The formation has been long colloquially known as "Una's Tits". The peaks appear on a British Antarctic Territory stamp although they are not identified as such. The individual towers are referred to as "buttresses". Una Spivey was the name of a secretary in the governor's office in Stanley, Falkland Islands who was working for what is now the British Antarctic Survey. The tallest tower has only been summited once; this was by a German team in 1999 (Kurt Albert, Stefan Glowacz, Hans Martin Götz, Gerhard Heidorn, Holger Heuber and Jürgen Knappe).

Lemaire Channel
Lemaire Channel is a strait off Antarctica, between Kyiv Peninsula in the mainland's Graham Land and Booth Island. Nicknamed "Kodak Gap" by some, it is one of the top tourism, tourist destinations in Antarctica; steep cliffs hem in the iceberg-filled passage, which is long and just wide at its narrowest point. It was first seen by the German expedition of 1873-74, but not traversed until December 1898, when the ''RV Belgica (1884), Belgica'' of the Belgian Antarctic Expedition passed through. Expedition leader Adrien de Gerlache named it for Charles Lemaire (explorer), Charles Lemaire (1863-1925), a Belgian explorer of the Congo. The channel has since become a standard part of the itinerary for Cruising (maritime), cruising in Antarctica; not only is it scenic, but the protected waters are usually as still as a lake, a rare occurrence in the storm-wracked southern seas, and the north-south traverse delivers vessels close to Petermann Island for landings.

Polar Record
''Polar Record'' is a quarterly peer-reviewed academic journal covering all aspects of Arctic and Antarctic exploration and research. It is managed by the Scott Polar Research Institute and published by Cambridge University Press. The journal was established in 1931 and the Co-editors-in-chief are Dr Nikolas Sellheim (University of Helsinki) and Dr Trevor McIntyre (University of South Africa). Abstracting and indexing The journal is abstracted and indexed in: The journal had a 2019 impact factor of 0.84. History The journal was established in 1931, by The Scott Polar Research Institute which itself was founded in 1926. The foreword of the first issue in the first volume stated that the journal was created to address the challenge of "so much exploration and exploitation in the polar regions, the news of which appear in so many forms and languages", and that "in the first place an attempt will be made merely to record the chief polar events of the preceding six months; but it i ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about away across the Drake Passage. The Antarctic Peninsula is in area and 80% ice-covered. The marine ecosystem around the western continental shelf of the Antarctic Peninsula (WAP) has been subjected to rapid climate change. Over the past 50 ...

British Antarctic Territory
The British Antarctic Territory (BAT) is a sector of Antarctica claimed by the United Kingdom as one of its 14 British Overseas Territories, of which it is by far the largest by area. It comprises the region south of 60°S latitude and between longitudes and , forming a wedge shape that extends to the South Pole, overlapped by the Antarctic claims of Argentina (Argentine Antarctica) and Chile (Chilean Antarctic Territory). The Territory was formed on 3 March 1962, although the UK's claim to this portion of the Antarctic dates back to letters patent of 1908 and 1917. The area now covered by the Territory includes three regions which, before 1962, were administered by the British as separate dependencies of the Falkland Islands: Graham Land, the South Orkney Islands, and the South Shetland Islands. The United Kingdom's claim to the region has been suspended since the Antarctic Treaty came into force in 1961, Article 4 of which states "No acts or activities taking place ...

Buttresses
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient buildings, as a means of providing support to act against the lateral (sideways) forces arising out of inadequately braced roof structures. The term ''counterfort'' can be synonymous with buttress and is often used when referring to dams, retaining walls and other structures holding back earth. Early examples of buttresses are found on the Eanna Temple (ancient Uruk), dating to as early as the 4th millennium BC. Terminology In addition to flying and ordinary buttresses, brick and masonry buttresses that support wall corners can be classified according to their ground plan. A clasping or clamped buttress has an L shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses are set back from the c ...

British Antarctic Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

Kurt Albert
Kurt Albert (January 28, 1954 – September 28, 2010) was a climber and photographer. He started climbing at the age of 14. Before he committed himself to a career of climbing in 1986, he was a mathematics and physics teacher. Climbing career At the age of seventeen, he climbed the Walker Spur in the Grandes Jorasses, and one year later he climbed the north face of the Eiger. After a visit to the Saxon Switzerland climbing area in Saxony, Germany in 1973 he recognized the potential of free climbing. He started to free climb in his home climbing area, the Frankenjura. In the routes, he would now try to ascend while free climbing, he would—in between attempts—paint a red 'X' on the rocks near pitons he did not need as holds or steps. Once he could place a red 'X' on all the pitons and hooks in the route, and was thus able to free climb the entire route, he would paint a red dot at the base of the route. From this comes the English term "redpoint", which is derived fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
