what time is it in antarctica and got the best answer
Answer from Helga[guru]
Antarctica is a place where everything looks the same. Everything seems the same, but not the time. On this continent, time zones intersect and overlap.
Most Antarctic stations have the time of the state to which this station belongs. Since the stations are located randomly, surprising paradoxes sometimes arise. It is enough to drive a couple of kilometers to the neighboring Antarctic station to get a few hours back. A map of "time zones" in Antarctica is attached. It's funny that the time at stations Scott (NZ) and Rothera (UK) differs by as much as fifteen hours. Although the stations are not located in different parts of the globe.
Time zones in Antarctica
At the North and South Poles, the meridians converge at one point, and therefore the concept of time zones, and at the same time local time, loses its meaning there. It is believed that time at the poles corresponds to universal time, but at Amundsen-Scott station (South Pole) New Zealand time is valid, and not universal time at all.

Hey! Here is a selection of topics with answers to your question: what time is it in Antarctica
The official version says that Antarctica was discovered during the Russian expedition of Bellingshausen and Lazarev in 1820. But by the end of the 19th century, researchers doubted this fact and put forward a hypothesis that the discovery of the mainland happened much earlier. The reason for this was a map compiled by the Turkish admiral Piri Rais ...
Ancient subglacial lake discovered in Antarctica
Antarctica on an ancient map
When compiling maps, Rice used manuscripts that survived after the destruction of the Library of Alexandria by the Arabs. The map around which passions flared up was dated 1513. Interestingly, the mountain ranges of Antarctica were marked on it, which are now buried under a layer of ice and were discovered more recently using seismic sounding.
It's curious that almost all ancient geographers were firmly convinced of the existence of a certain continent in the South. There was also legendary information about the land in the South, dating back to the 15th century BC.
In 1897, the English steam brig Queen Elizabeth anchored in a creek off the Antarctic coast of Queen Maud Land. It should be noted that this year turned out to be abnormally hot throughout the globe. When the sailors climbed a small plateau 10 miles from the coast, they saw that the ruins of unknown structures had thawed out from under the many meters of ice. Unfortunately, it turned out to be impossible to get inside, since the lower part of the structures was still under the ice ...
Based on the sensational find, a special expedition was planned, which was to take place in 1899. But the Anglo-Boer War began, and with its beginning all plans were forgotten. And only in the second half of the 20th century, in 1977, the research was continued thanks to new unexpected finds.
Mysterious golden hairs in Antarctica
Then experimental studies were carried out in the ice basin of the Arctic and Antarctic Research Institute. An expedition from Antarctica unloaded ice cores obtained by drilling a kilometer-long layer of ice over one of the subglacial Antarctic lakes. It has been suggested that this ice should not be used, much less melted, until it is found to be free of pathogens.
And then they decided to involve biologists in the research. Samples were taken for analysis, which showed that one of the samples contained short gold wires as thick as a human hair, as well as wood chips. It is interesting that the length of the metal hairs was 2 centimeters, and all the hairs found in different samples had the same length, even ends, and had almost no elasticity. During the experiment, they were squeezed with tweezers, and dents appeared on them.
These mysterious hairs did not dissolve either in hydrochloric or sulfuric, or in nitric or acetic acids, which is characteristic only of gold ...
There is also evidence from Norwegian archaeologists dating back to the late 80s. They claim to have found gold jewelry, dishes, masks and even unknown tools under the Antarctic ice. True, this discovery was “silenced” in scientific circles, since it went very much contrary to the generally accepted version of the history of the mainland ...
Apparently, in ancient geological eras, Antarctica was distinguished by a warm climate, an abundance of flora and fauna. A natural disaster that changed conditions on the mainland most likely destroyed the bridges connecting eastern Antarctica with Africa and South America. Findings found in layers 280-320 million years old have become evidence of climate change.
Among them are the fossil remains of plants and animals, including ichthyosaurs, which were heat-loving reptiles, and fern flora.
In January 1820, a Russian expedition led by Thaddeus Bellingshausen and Mikhail Lazarev discovered Antarctica, the existence of which had only been speculated before. Today we have collected for you interesting and little-known facts about the most remote southern mainland - the highest, dry, windy, sparsely populated and coldest place on earth.
1. At one time in Antarctica it was impossible to work for those who had not removed their wisdom teeth and appendix. Due to the fact that no surgical operations were performed at the stations of Antarctica, in order to work here, one had to first part with these parts of the body, even if they were completely healthy.
3. Like many countries, Antarctica has its own Internet domain - .aq
4. 53 million years ago, Antarctica was so warm that palm trees grew on its shores, and the air temperature rose above 20 degrees Celsius.
5. In December 2013, Metallica played a concert in Antarctica, thus becoming the first band in the world to perform on all continents. In order not to disturb the local fauna, the concert was held under a special protective dome, and the audience listened to music through headphones.
6. From 1960 to 1972, McMurdo Station, the largest settlement and research center owned by the United States, operated the first nuclear power plant in Antarctica.
7. Antarctica has its own fire station. It belongs to the McMurdo station, and the most real professional firefighters work on it.
8. Despite extreme conditions, 1,150 species of fungi have been found in Antarctica. They are highly adaptable to extreme cold temperatures and extended periods of freeze and thaw.
9. Technically, all 24 time zones are present in Antarctica, since their boundaries converge at one point at both poles.
10. There are no polar bears in Antarctica. To see them, you will have to go to the North Pole or, for example, to Canada.
11. There is a bar in Antarctica - the southernmost bar on the planet. And it is located at the Akademik Vernadsky station, which belongs to Ukraine.
12. The lowest temperature ever recorded on earth - minus 89.2 degrees Celsius - was recorded in Antarctica at the Russian Vostok station on July 21, 1983.
15. The average ice thickness of Antarctica is 1.6 km. Antarctica contains about 70% of all fresh water on earth.
16. The Transantarctic Mountains run through the entire continent and divide it into western and eastern parts. This range is one of the longest in the world - its length is 3500 km.
17. The existence of the continent of Antarctica was unknown until its discovery in 1820. Before that, it was assumed that this is just a group of islands.
18. On December 14, 1911, Norwegian explorer Roald Amundsen became the first person to reach the South Pole and hoist the flag of his nation there. He also became the first person to visit both geographic poles of the planet.
19. As a result of secret negotiations on December 1, 1959, 12 countries concluded the Antarctic Treaty, which provides for the demilitarization of the Antarctic region and its use for exclusively peaceful purposes. To date, more than 50 countries are parties to the Treaty.
20. On January 7, 1978, the Argentine Emilio Marcos Palma was born - the first person in history to be born in Antarctica. It is believed that this event was a planned action by the Argentine government, which specially sent a pregnant woman to the Esperanza station in order to subsequently claim part of the territory of Antarctica.
Perhaps there is no place in the world more mysterious than Antarctica. The boundless expanses bound by ice could tell a lot about what the Earth was like millions of years ago. But nature is in no hurry to reveal its secrets, and man returns here again and again, struggling with cold and blizzard.
Antarctica is the icy heart of Antarctica: on an area of 13 million 661 thousand km 2 there are 30 million km 3 of ice! The geographic South Pole, the Pole of Cold (-89.2 °C - the lowest temperature), the Pole of Inaccessibility, conquered by the Soviet expedition in 1958, the South Geomagnetic Pole pass through the mainland.
The territory of the mainland does not belong to any of the countries. In Antarctica, it is impossible to engage in the development of minerals or carry out industrial work - only scientific activities are allowed, therefore, in addition to seals and penguins, the mainland is inhabited by scientists from different countries. Only well-trained people, strong in both spirit and body, live and work here. The reason for this is extreme conditions and a harsh climate.
Features of the climate of Antarctica
The warmest time on the mainland is from November to February - this is spring and summer in the Southern Hemisphere. On the coast, the air can warm up to 0°C, and near the cold pole, the temperature rises to -30°C.
Summer in Antarctica is so sunny that in no case should you forget about sunglasses - you can seriously damage your eyesight. And you can’t do without lipstick either - without it, your lips instantly crack, and it’s impossible to eat or talk. Why, then, is it so cold, and the glaciers do not melt? Almost 90% of solar energy is reflected from ice and snow cover, and given that the mainland receives solar heat mainly in summer, it turns out that during the year Antarctica loses more heat than it gains.
The lowest temperature is from March to October, autumn and winter in Antarctica, when the thermometer drops to -75°C. This is a period of severe storms, planes do not arrive on the mainland, and polar explorers are cut off from the rest of the world for a long 8 months.
Polar day and polar night in the Southern Hemisphere
Pictured is an aurora near McMurdo Station on July 15, 2012.
In Antarctica, as well as in the Northern Hemisphere, there are polar night and polar day, which last around the clock. If you rely only on astronomical calculations, then on December 22, on the day of the summer solstice in the Southern Hemisphere, the sun at midnight should only half disappear below the horizon, and then rise again. And on June 22, on the day of the winter solstice - only half appear on the horizon at noon, and then disappear. But there is astronomical refraction - an optical phenomenon associated with the refraction of light rays. Thanks to refraction, we see the luminaries before they appear above the horizon, and for some time after they set. Therefore, the usual change of day and night occurs only in spring and autumn. In winter, polar night reigns, and in summer - polar day.
Nature of Antarctica
A kind of visiting card of Antarctica is a penguin. Several species of these funny birds live here: on the continental coast - emperor, king, gentoo penguin, Adélie penguin. And on the Antarctic and subantarctic islands live crested, arctic, golden-haired penguins.
There are other birds: petrels (Antarctic, snowy, silver gray), skuas,
Antarctica is the habitat of several species of seals: Weddell seal, Ross seal, crabeater seal, southern elephant seal, leopard seal, Kerguelen fur seal.
Whales live here: blue whale, flat-fronted bottlenose, sperm whale, killer whales, sei whale, southern minke whale.
It is hard to imagine, but even here, on the icy continent, there is vegetation. Lichens, cereal and clove herbs, whose height does not exceed 1 cm, and some types of moss hide in the crevices of the rocks.
Polar stations of Antarctica

Most of the stations are located in the coastal zone of the continent, and only three of them are located in the depths. These are the American Amundsen-Scott base, the Franco-Italian Concordia and the Russian Vostok base.
An interesting story is connected with the opening of Vostok. When in the early 1950s, at a meeting in Paris, the issues of the development of Antarctica were being decided, our delegation was given the task of proving at all costs that the Soviet Union had enough resources to maintain the operation of the station at the very South Geographic Pole. But due to delays with passports and visas, our delegate was late for the beginning of the meeting, and this place had already been promised to the Americans. We got the South geomagnetic pole and the pole of inaccessibility. In 1957, the scientific station "Vostok" was founded at the South geomagnetic pole. And 50 years later, scientists managed to get a sample of the water from an underground lake, which, as it turned out, was located right under the station! Fifth in terms of volume of fresh water, hidden under the ice at a depth of almost 4000 m, Lake Vostok sheds light on the origin of the Earth and life on Earth. This is incredible luck!
Pictured is a spring sunset near Palmer Arctic Station on March 31, 2011.
In total, there are 5 Russian bases in Antarctica that operate all year round: Bellingshausen, Mirny, Vostok, Progress, Novolazarevskaya. Scientists study the atmosphere, weather, ice, the movement of the earth's crust. All bases have the most comfortable conditions: in addition to everything necessary for work, there are rest rooms, a gym, billiards, a library. IP-telephony and Internet access have been established, broadcasting of the 1st channel is being broadcast.
The closest neighbors of scientists from the Novolazarevskaya base are specialists from India. The name of their base - "Maitri" - means "friendship" and best describes the relationship between polar explorers. By the way, the warm, friendly atmosphere has always been here. Even during the Cold War, scientists conducted joint research, used each other's achievements.
Pictured is a satellite communications dish at McMurdo Antarctic Station.
In addition to traditional holidays, the bases celebrate the beginning and end of each expedition. At a gala dinner, a symbolic handover of the key to the station takes place. Despite an early meeting with their relatives, scientists leaving the station involuntarily envy those who stay for the winter - Antarctica does not let go. Cold, blizzard, but so beautiful.
