Research Stations In Antarctica
Multiple governments have set up permanent research stations in Antarctica and these bases are widely distributed. Unlike the drifting ice stations set up in the Arctic, the research stations of the Antarctic are constructed either on rock or on ice that is (for practical purposes) fixed in place. Many of the stations are staffed throughout the year. A total of 42 countries (as of October 2006), all signatories to the Antarctic Treaty, operate seasonal (summer) and year-round research stations on the continent. The population of people performing and supporting scientific research on the continent and nearby islands varies from approximately 4,000 during the summer season to 1,000 during winter (June). In addition to these permanent stations, approximately 30 field camps are established each summer to support specific projects. History First bases During the Heroic Age of Antarctic Exploration in the late 19th century, the first bases on the continent were established. I ...

Antarctica Station Map
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual Climate of Antarctica#Precipitation, precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the Lowest temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer.

Operation Tabarin
Operation Tabarin was the code name for a secret British expedition to the Antarctic during World War Two, operational 1943–46. Conducted by the Admiralty on behalf of the Colonial Office, its primary objective was to strengthen British claims to sovereignty of the British territory of the Falkland Islands Dependencies (FID), to which Argentina and Chile had made counter claims since the outbreak of war. This was done by establishing permanently occupied bases, carrying out administrative activities such as postal services and undertaking scientific research. The meteorological observations made aided Allied shipping in the South Atlantic Ocean. Following Cabinet approval in January 1943, there was an intensive period of planning, recruitment and procurement, before the expedition left the UK in November 1943, led by Lieutenant-Commander James Marr. Two bases were established in early 1944 – firstly, Base B, at Deception Island, South Shetland Islands, and later the main base, ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war. World War II was by far the List of wars by death toll, deadliest conflict in hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stonemasonry
Stonemasonry or stonecraft is the creation of buildings, structures, and sculpture using stone as the primary material. It is one of the oldest activities and professions in human history. Many of the long-lasting, ancient shelters, temples, monuments, artifacts, fortifications, roads, bridges, and entire cities were built of stone. Famous works of stonemasonry include the Egyptian pyramids, the Taj Mahal, Cusco's Incan Wall, Easter Island's statues, Angkor Wat, Borobudur, Tihuanaco, Tenochtitlan, Persepolis, the Parthenon, Stonehenge, the Great Wall of China, and Chartres Cathedral. Definition Masonry is the craft of shaping rough pieces of rock into accurate geometrical shapes, at times simple, but some of considerable complexity, and then arranging the resulting stones, often together with mortar, to form structures. *Quarrymen split sheets of rock, and extract the resulting blocks of stone from the ground. *Sawyers cut these rough blocks into cuboids, to requ ...

Mortar (masonry)
Mortar is a workable paste which hardens to bind building blocks such as stones, bricks, and concrete masonry units, to fill and seal the irregular gaps between them, spread the weight of them evenly, and sometimes to add decorative colors or patterns to masonry walls. In its broadest sense, mortar includes pitch, asphalt, and soft mud or clay, as those used between mud bricks, as well as cement mortar. The word "mortar" comes from Old French ''mortier'', "builder's mortar, plaster; bowl for mixing." (13c.). Cement mortar becomes hard when it cures, resulting in a rigid aggregate structure; however, the mortar functions as a weaker component than the building blocks and serves as the sacrificial element in the masonry, because mortar is easier and less expensive to repair than the building blocks. Bricklayers typically make mortars using a mixture of sand, a binder, and water. The most common binder since the early 20th century is Portland cement, but the ancient binder l ...

Dry Stone
Dry stone, sometimes called drystack or, in Scotland, drystane, is a building method by which structures are constructed from stones without any mortar to bind them together. Dry stone structures are stable because of their construction method, which is characterized by the presence of a load-bearing façade of carefully selected interlocking stones. Dry stone construction is best known in the context of stone walls, traditionally used for the boundaries of fields and churchyards, or as retaining walls for terracing, but dry stone sculptures, buildings, bridges, and other structures also exist. The term tends not to be used for the many historic styles which used precisely-shaped stone, but did not use mortar, for example the Greek temple and Inca architecture. The art of dry stone walling was inscribed in 2018 on the UNESCO representative list of the intangible cultural heritage of humanity, for dry stone walls in countries such as France, Greece, Italy, Slovenia, Cr ...

Laurie Island
Laurie Island is the second largest of the South Orkney Islands. The island is claimed by both Argentina as part of Argentine Antarctica, and the United Kingdom as part of the British Antarctic Territory. However, under the Antarctic Treaty System all sovereignty claims are frozen, as the island lies south of the parallel 60°. Buchanan Point at the north-eastern end of the island, with Cape Whitson on its south coast, are Important Bird Areas. History Laurie Island was discovered by Captains George Powell and Nathaniel Palmer in the course of their 1821 expedition to the South Atlantic. Richard Holmes Laurie used Powell's observations to create a map of the island, and subsequently, the island was named after him. Two years later, James Weddell mapped the island for the second time, though his charts turned out to be much less accurate than Powell's charts. Weddell attempted to rename the island to Melville Island for the 2nd Viscount Melville, but the name failed to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scottish National Antarctic Expedition
The Scottish National Antarctic Expedition (SNAE), 1902–1904, was organised and led by William Speirs Bruce, a natural scientist and former medical student from the University of Edinburgh. Although overshadowed in terms of prestige by Robert Falcon Scott's concurrent Discovery Expedition, the SNAE completed a full programme of exploration and scientific work. Its achievements included the establishment of a staffed meteorological station, the first in Antarctic territory, and the discovery of new land to the east of the Weddell Sea. Its large collection of biological and geological specimens, together with those from Bruce's earlier travels, led to the establishment of the Scottish Oceanographical Laboratory in 1906. Bruce had spent most of the 1890s engaged on expeditions to the Antarctic and Arctic regions, and by 1899 was Britain's most experienced polar scientist. In March of that year, he applied to join the Discovery Expedition; however, his proposal to extend th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Speirs Bruce
William Speirs Bruce (1 August 1867 – 28 October 1921) was a British naturalist, polar scientist and oceanographer who organized and led the Scottish National Antarctic Expedition (SNAE, 1902–04) to the South Orkney Islands and the Weddell Sea. Among other achievements, the expedition established the first permanent weather station in Antarctica. Bruce later founded the Scottish Oceanographical Laboratory in Edinburgh, but his plans for a transcontinental Antarctic march via the South Pole were abandoned because of lack of public and financial support. In 1892 Bruce gave up his medical studies at the University of Edinburgh and joined the Dundee Whaling Expedition to Antarctica as a scientific assistant. This was followed by Arctic voyages to Novaya Zemlya, Spitsbergen and Franz Josef Land. In 1899 Bruce, by then Britain's most experienced polar scientist, applied for a post on Robert Falcon Scott's Discovery Expedition, but delays over this appointment and clashes with ...
