At 0.00008 people per square kilometre, it is by far the least densely populated continent. In 1984, Juan Pablo Camacho was born at the Frei Montalva Station, becoming the first Chilean born in Antarctica. Many of the stations are staffed year-round, the winter-over personnel typically arriving from their home countries for a one-year assignment. It was eventually determined that the destruction of the ozone was caused by chlorofluorocarbons (CFCs) emitted by human products. Weird things about the name Antarctica: The name spelled backwards is … Some environmentalists and scientists have made a call for stricter regulations for ships and a tourism quota. However, belief in the existence of a Terra Australis—a vast continent in the far south of the globe to "balance" the northern lands of Europe, Asia and North Africa—had prevailed since the times of Ptolemy in the 1st century AD. The sheet has been of recent concern because of the small possibility of its collapse. There are only about 4.000 people working in Antarctica during the summer and around 1.000 during winter. [17], Antarctica has no indigenous population. [45] The first women to step onto the South Pole were Pam Young, Jean Pearson, Lois Jones, Eileen McSaveney, Kay Lindsay and Terry Tickhill in 1969. English Translation. [7] The temperature in Antarctica has reached −89.2 °C (−128.6 °F) (or even −94.7 °C (−135.8 °F) as measured from space[8]), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). Vegetation, where it occurs, is tundra. [106] Bacteria have been found living in the cold and dark as deep as 800 m (0.50 mi; 2,600 ft) under the ice. These are floating extensions of outflowing glaciers from the continental ice mass. Most of these meteorites have fallen onto the ice sheet in the last million years. During the Permian period, the land became dominated by seed plants such as Glossopteris, a pteridosperm which grew in swamps. He justified the titling of his book A Voyage to Terra Australis (1814) by writing in the introduction: There is no probability, that any other detached body of land, of nearly equal extent, will ever be found in a more southern latitude; the name Terra Australis will, therefore, remain descriptive of the geographical importance of this country and of its situation on the globe: it has antiquity to recommend it; and, having no reference to either of the two claiming nations, appears to be less objectionable than any other which could have been selected. West Antarctica is covered by the West Antarctic Ice Sheet. Learn the meaning of Antarctica, origin, popularity and more name info. Antarctica was not quite the way she had imagined it, Joselén says, smiling. www.tagalog-dictionary.com Batchoy Tagalog perfect for cold weather - YouTube Biologists, in addition to examining the wildlife, are interested in how harsh temperatures and the presence of people affect adaptation and survival strategies in a wide variety of organisms. This reduced the formation of the 'polar stratospheric clouds' that enable the chemistry that leads to rapid ozone loss. There are no permanent residents, meaning that researchers and other personnel fly in and out every few months or so. Synapsids, commonly known as "mammal-like reptiles", were common in Antarctica during the Early Triassic and included forms such as Lystrosaurus. The elapsed time since fall, or terrestrial residence age, of a meteorite represents more information that might be useful in environmental studies of Antarctic ice sheets. Another well-known volcano is found on Deception Island, which is famous for a giant eruption in 1970. Currently, the Polar Geospatial Center can image all of Antarctica at 500 mm (20 in) resolution every 45 days. antarctic translation in English-Tagalog dictionary. [40] The first women to set foot on Antarctica did so in the 1930s with Caroline Mikkelsen landing on an island of Antarctica in 1935,[41] and Ingrid Christensen stepping onto the mainland in 1937. The illegal fishing of toothfish has been increasing, with estimates of 32,000 tonnes (35,000 short tons) in 2000. [84], The first child born in the southern polar region was Norwegian girl Solveig Gunbjørg Jacobsen, born in Grytviken on 8 October 1913, and her birth was registered by the resident British Magistrate of South Georgia. Another word for Opposite of Meaning of Rhymes with Sentences with Find word forms Translate from English Translate to English Words With Friends Scrabble Crossword / Codeword Words starting with Words ending with Words containing exactly Words containing letters Pronounce Find conjugations Find names The Antarctic Treaty prohibits any military activity in Antarctica, including the establishment of military bases and fortifications, military manoeuvres, and weapons testing. [143] The impacts of the depleted ozone layer on climate changes occurring in Antarctica are not well understood. However, it is the outflow of the ice from the land to form the ice shelf which causes a rise in global sea level. All but a small portion of this region lies within the Eastern Hemisphere. The Polar Geospatial Center uses geospatial and remote sensing technology to provide mapping services to American federally funded research teams. [122] The only documented military land manoeuvre has been the small Operation NINETY by the Argentine military in 1965.[123]. [141], Since the 1970s an important focus of study has been the ozone layer in the atmosphere above Antarctica. [180] Models also suggest that the ozone depletion/enhanced polar vortex effect also accounts for the recent increase in sea ice just offshore of the continent. Africa separated from Antarctica in the Jurassic, around 160 Ma, followed by the Indian subcontinent in the early Cretaceous (about 125 Ma). A closely related slang word is syota (sho-tah) which has a stigma attached to it since it originates from the Filipino phrase for “short time,” implying the relationship isn’t a serious one. ... Guam looking for Filipino workers for construction projects August 08, 2020. Antarctica, the world’s southernmost continent, is almost wholly covered by an ice sheet and is about 5.5 million square miles (14.2 million square km) in size. A lower air temperature of −94.7 °C (−138.5 °F) was recorded in 2010 by satellite—however, it may be influenced by ground temperatures and was not recorded at a height of 7 feet (2 m) above the surface as required for the official air temperature records. Showing page 1. Offshore, temperatures are also low enough that ice is formed from seawater through most of the year. In the summer more than 4,000 scientists operate research stations; this number decreases to just over 1,000 in the winter. How unique is the name Antarctic? Antarctica is noted as the last region on Earth in recorded history to be discovered, unseen until 1820 when the Russian expedition of Fabian Gottlieb von Bellingshausen and Mikhail Lazarev on Vostok and Mirny sighted the Fimbul ice shelf. [167] The amount of surface warming in West Antarctica, while large, has not led to appreciable melting at the surface, and is not directly affecting the West Antarctic Ice Sheet's contribution to sea level. Richard E. Byrd led several voyages to the Antarctic by plane in the 1930s and 1940s. This means that it is a very cold continent where water is mostly in the form of ice. [6] Most of Antarctica is a polar desert, with annual precipitation of 200 mm (7.9 in) along the coast and far less inland; there has been no rain there for almost 2 million years, yet 80% of the world freshwater reserves are stored there, enough to raise global sea levels by about 60 metres (200 ft) if all of it were to melt. [74] The lowest natural air temperature ever recorded on Earth was −89.2 °C (−128.6 °F) at the Russian Vostok Station in Antarctica on 21 July 1983. [108], The passing of the Antarctic Conservation Act (1978) in the U.S. brought several restrictions to U.S. activity on Antarctica. [119] The following year, however, Australia and France announced that they would not ratify the convention, rendering it dead for all intents and purposes. The Argentine, British and Chilean claims all overlap, and have caused friction. Robertson Land, Wilkes Land, and Victoria Land. Twelve countries signed the Antarctic Treaty in 1959, and thirty-eight have signed it since then. [142], In September 2006 NASA satellite data revealed that the Antarctic ozone hole was larger than at any other time on record, at 2,750,000 km2 (1,060,000 sq mi). [93] Invertebrate life includes microscopic mites like the Alaskozetes antarcticus, lice, nematodes, tardigrades, rotifers, krill and springtails. The researchers present a complete temperature record from Antarctica's Byrd Station and assert that it "reveals a linear increase in annual temperature between 1958 and 2010 by 2.4±1.2 °C". Scientists discovered 11 new colonies, meaning there are now 61 colonies across the continent overall. [124] On 22 December 2012, the UK ambassador to Argentina, John Freeman, was summoned to the Argentine government as protest against the claim. Out of 6,028,151 records in the U.S. Social Security Administration public data, the first name Antarctica was not present. Several bases are now home to families with children attending schools at the station. The Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR), a treaty that came into force in 1980, requires that regulations managing all Southern Ocean fisheries consider potential effects on the entire Antarctic ecosystem. During the Nimrod Expedition led by Ernest Shackleton in 1907, parties led by Edgeworth David became the first to climb Mount Erebus and to reach the South Magnetic Pole. In coastal areas such as Shackleton Range and Victoria Land some faulting has occurred. The proportion of the Philippines flag is 1:2. Much is unknown regarding the history of the Tagalogs prior to the Spanish Colonization of the Philippine Islands in the 16th Century. [21] Cook came within about 120 km (75 mi) of the Antarctic coast before retreating in the face of field ice in January 1773.[22]. Ibig ipakahulugan ng matalinghagang salita: Ang tren ay parang alupihan. This hole covers almost the whole continent and was at its largest in September 2008, when the longest lasting hole on record remained until the end of December. [100][101] Some of these species are cryptoendoliths as a result of evolution under extreme conditions, and have significantly contributed to shaping the impressive rock formations of the McMurdo Dry Valleys and surrounding mountain ridges. While a few of these countries have mutually recognised each other's claims,[111] the validity of these claims is not recognised universally.[1]. [1] McMurdo Station, which is the largest research station in Antarctica, is capable of housing more than 1,000 scientists, visitors, and tourists. As a result of continued warming, the polar ice caps melted and much of Gondwana became a desert. Antarctica contains many other mountains, on both the main continent and the surrounding islands. Discovery and claim of French sovereignty over Adélie Land by Jules Dumont d'Urville, in 1840.

Minor eruptions are frequent, and lava flow has been observed in recent years. Gayunman, hindi tatawaging tahanan ng kahit isang tao ang, Holes, regions with drastically reduced ozone levels, are left in the ozone layer, both in, Ang mga butas, mga rehiyon na lubhang nabawasan ang mga antas ng ozone, ay naiwan sa ozone layer, kapuwa sa, The longest blue whale on record was a 108-foot [33 m] adult female caught in, Ang pinakamahabang blue whale na naitala ay isang 33-metrong adultong babaing blue whale na nahuli sa, In 2013, the Wiki Loves Monuments competition was held across six continents including, Noong 2013, ginanap ang Wiki Loves Monuments sa anim na kontinente, kabilang dito ang, Una, dahil sa simpleng mga ugnayan ng ekolohiya ng. The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1,000 in winter to about 5,000 in the summer, giving it a population density between 70 and 350 inhabitants per million square kilometres (180 and 900 per million square miles) at these times. More than 170 million years ago, Antarctica was part of the supercontinent Gondwana. They searched for a more poetic replacement, suggesting various names such as Ultima and Antipodea. As a result, the diversity of plant life is very low and limited in distribution. [179] The hole was detected by scientists in 1985[180] and has tended to increase over the years of observation. The treaty prohibits military activities and mineral mining, prohibits nuclear explosions and nuclear waste disposal, supports scientific research, and protects the continent's ecology. [80], Several governments maintain permanent manned research stations on the continent. Heavy snowfalls are common on the coastal portion of the continent, where snowfalls of up to 1.22 metres (48 in) in 48 hours have been recorded. If the sheet were to break down, ocean levels would rise by several metres in a relatively geologically short period of time, perhaps a matter of centuries. [18] In February 1775, during his second voyage, Captain Cook called the existence of such a polar continent "probable" and in another copy of his journal he wrote: "[I] firmly believe it and it's more than probable that we have seen a part of it".[19]. If life is discovered in Lake Vostok, it would strengthen the argument for the possibility of life on Europa. Military personnel or equipment are permitted only for scientific research or other peaceful purposes. It is important to understand the various types of Antarctic ice to understand possible effects on sea levels and the implications of global cooling. [99], About 1,150 species of fungi have been recorded from Antarctica, of which about 750 are non-lichen-forming and 400 are lichen-forming.
