The harmful fishing methods used by IUU fishing vessels also cause the direct deaths of countless seabirds. Illegal, unregulated and unreported (IUU) fishing also threatens fish stocks in some areas of the Southern Ocean and thereby the seabirds and marine mammals that depend upon them. As global fisheries become depleted, there is growing interest to expand fishing throughout the region.
Everything you need to know about Antarctica
In January 2025, the detachment of the massive iceberg A-84 (comparable in size to the city of Chicago) from the George VI Ice Shelf provided a rare opportunity to explore the seafloor beneath floating ice shelves using robotic submersibles. Factors that may aid in their distribution include temperature differences between the deep ocean at the poles and the equator of no more than 5 °C (9 °F) and the major current systems or marine conveyor belts which are able to transport eggs and larva. Smaller forms of life, such as sea cucumbers and free-swimming snails, are also found in both polar oceans. The research found that more than 235 marine organisms live in both polar regions, having bridged the gap of 12,000 km (7,456 mi). The emperor penguin is the only penguin that breeds during the winter in Antarctica; it and the Adélie penguin breed farther south than any other penguin.
Antarctica has no indigenous inhabitants, although scientific researchers can live in the Antarctic all year round. On the southern polar plateau, the ice cap is up to 4km thick, meaning that explorers are just as likely to suffer from altitude sickness as frostbite. If this ice were permanent, Antarctica would be the third largest continent on Earth, only behind Asia and Africa. The nearest other land mass is South America – but even that is 600 miles away, across the roughest seas in the world.
Here’s a checklists of tasks we recommend for your first day with Google Workspace
- Antarctica is, on average, the coldest, driest, and windiest of the continents, and has the highest average elevation.
- Ecosystems are impacted by local and global threats, notably pollution, the invasion of non-native species, and the various effects of climate change.
- There are numerous islands surrounding Antarctica, most of which are volcanic and very young by geological standards.
- If this ice were permanent, Antarctica would be the third largest continent on Earth, only behind Asia and Africa.
- Several Antarctic ice streams flow to one of the many Antarctic ice shelves, a process described by ice-sheet dynamics.
In the winter the continent almost doubles in size due to the sea-ice that forms around the coast. About 4,000 visiting scientists, spread across 70 research stations, inhabit the continent during the summer. Its size varies through the seasons, as expanding sea ice along the coast nearly doubles the continent’s size in the winter. Discover interesting facts about Antarctica, the-ice covered continent that’s home to penguins, seals and a wealth of scientific research. Although no one permanently resides in Antarctica, the continent hosts more than 70 scientific research stations operated by over 30 countries.
Glaciers slowly move across the continent and break off into the sea. American seal hunter John Davis was the first to say he landed on Antarctica in 1821, although some historians dispute his claim. The frozen southern continent wasn’t discovered until 1820.
What animals live in Antarctica?
The first child born in the southern polar region was a Norwegian girl, Solveig Gunbjørg Jacobsen, born in Grytviken on 8 October 1913. During the whaling era, which lasted until 1966, the population of the island varied from over 1,000 in the summer (over 2,000 in some years) to some 200 in the winter. During the Nimrod Expedition led by the British explorer Ernest Shackleton in 1907, parties led by Edgeworth David became the first to climb Mount Erebus and to reach the south magnetic pole. The first confirmed landing on the continental mass of Antarctica occurred in 1895 when the Norwegian-Swedish whaling ship Antarctic reached Cape Adare. The oldest known human remains in the Antarctic region was a skull, dated from 1819 to 1825, that belonged to a young woman on Yamana Beach at the South Shetland Islands.
The treaty set aside Antarctica as a scientific preserve and established freedom of scientific investigation and environmental protection. Antarctic English, a distinct variety of the English language, has been found to be spoken by people living on Antarctica and the subantarctic islands. Military personnel or equipment are permitted only for scientific research or other peaceful purposes. Emilio Marcos Palma was the first person born south of the 60th parallel south and the first to be born on the Antarctic mainland at the Esperanza Base of the Argentine Army, on 7 January 1978.
Keep whales safe on their ocean journeys
The oceans surrounding Antarctica are home to many types of whales. Scientists take turns going there to study the ice. Antarctica is too cold for people to live there for a long time. Would you take a swim in this ice water off the coast of Antarctica? Antarctica’s terrain is made up of glaciers, ice shelves and icebergs – that’s a lot of ice!
How big is Antarctica?
- Biomedical scientists have made discoveries concerning the spreading of viruses and the body’s response to extreme seasonal temperatures.
- Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry, with moderate wind speeds.
- Melting ice sheets may impact sea levels all over the world.
- Antarctic ‘blizzards’ really consist of ice crystals being whipped up by the wind.
- They searched for a more poetic replacement, suggesting names such as Ultima and Antipodea.

The West Antarctic ice sheet is likely to melt completely unless temperatures are reduced by 2 °C (3.6 °F) below 2020 levels. On ice-free land, permafrost thaws release greenhouse gases and formerly frozen pollution. By 2100, net ice loss from Antarctica is expected to add about 11 cm (5 in) to global sea level rise. Antarctica is colder than the Arctic region, as much of Antarctica is over 3,000 m (9,800 ft) above sea level, where air temperatures are colder. Over the elevated inland, it can rise to about −30 °C in summer but fall below −80 °C in winter. Antarctica is the coldest, windiest, and driest of Earth’s continents.Near the coast, the temperature can exceed 10 °C in summer and fall to below −40 °C in winter.

The primary response by Antarctic Treaty parties has been to develop guidelines that set landing limits and closed or restricted zones on the more frequently visited sites. The claims by Britain, Australia, New Zealand, France, and Norway do not overlap and are recognised by each other. The UK passed some of the areas it claimed to Australia and New Zealand after they achieved independence. In 2012, after the British Foreign & Commonwealth Office designated a previously unnamed area Queen Elizabeth Land in tribute to Queen Elizabeth II’s Diamond Jubilee, the Argentine government protested against the claim. In the present, sovereignty over regions of Antarctica is claimed by seven different countries.
The Antarctic Film Festival is held annually between bases, with 48 stations registered to participate as of 2022. The southernmost music festival in the world, Icestock, has been held at McMurdo Station since 1989. Its aims include improving the understanding and predictions of these processes to aid decision makers in risk assessment, management, and mitigation related to Antarctic climate change.citation needed
This has led to speculation that life on Mars might have been similar to Antarctic fungi, such as Cryomyces antarcticus and Cryomyces minteri. Some of the species, having evolved under extreme conditions, have colonised structural cavities within porous rocks and have contributed to shaping the rock formations of the McMurdo Dry Valleys and surrounding mountain ridges. A Census of Marine Life by some 500 researchers during the International Polar Year was released in 2010. There are approximately 40 bird species that breed on or close to Antarctica, including species of petrels, penguins, cormorants, and gulls. Leopard seals are apex predators in the Antarctic ecosystem and migrate across the Southern Ocean in search of food. The Antarctic fur seal was very heavily hunted in the 18th and 19th centuries for its pelt by seal hunters from the United States and the United Kingdom.
Why Antarctica Matters
These shrimp-like creatures are the primary food source for countless species, including penguins, seals, and whales. In fact, Antarctica’s surrounding oceans are home to more than 8,000 marine species, more than half of which are seen nowhere else in the world. You can find half of the world’s penguin species, 15 species of whale and dolphin, as well as over 30 species of seabird and seal. Antarctica is a massive frozen landmass at the bottom of our planet and is the fifth-largest continent in total area. Southern elephant seals are the largest species of seal in Antarctica. Scientists can study ice cores like the one above to learn about the climate, organisms that survive in extreme conditions and more.
At the continent’s edge, strong katabatic winds off the polar plateau often blow at storm force. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry, with moderate wind speeds. In the dry valleys, the same effect occurs over a rock base, leading to a barren and desiccated landscape. In a few blue-ice areas, the wind and sublimation remove more snow than is accumulated by precipitation. The interior is drier and receives less than 50 mm (2 in) per year, whereas the coastal regions typically receive more than 200 mm (8 in). Antarctica is a polar desert with little precipitation; the continent receives an average equivalent to about 150 mm (6 in) of water per year, mostly in the form of snow.
Cook came within about 120 km (75 mi) of the Antarctic coast before retreating in the face of field ice in January 1773. Much larger than and unrelated to Antarctica, Terra Australis was a landmass that classical scholars presumed necessary to balance the known lands in the northern hemisphere. Early world maps, like the 1513 Piri Reis map, feature the hypothetical continent Terra Australis. All commercial whaling is banned in the zone, though Japan has continued to hunt whales in the area, ostensibly for research purposes.
It is located in an ice-free area known as the Vestfold Hills. Base Esperanza also houses the first Catholic chapel (1976) and first school (1978) built on the continent. The station is known for a number of Antarctica “firsts.” It is the birthplace of Emilio Marcos Palma, the first person to be born in Antarctica. Additional supplies and personnel are flown in from Christchurch, New Zealand, when weather permits.Base Esperanza, Argentina’s largest Antarctic facility, is located in Hope Bay on the tip of the Antarctic Peninsula. These cargo ships can only reach Winter Quarters Bay, McMurdo’s harbor, during summer, when the pack ice can be breached by U.S.
During the winter, Antarctica is in complete darkness for months. The average temperature at the South Pole Station is minus 18 F (minus 28 C) in the Southern Hemisphere’s summer and minus 76 F (minus 60 C) in the winter. Because Antarctica is in the Southern Hemisphere, the warmest time of the year is December through February, and the coldest time of the year is in June through August. Antarctica is the coldest, windiest and driest continent on Earth. These species survive in extreme conditions and play vital roles in the Southern Ocean’s ecosystem.
In 1824, the colonial authorities in Sydney officially renamed the continent of New Holland to Australia, leaving the term “Terra Australis” unavailable as a reference to Antarctica. The name given to the continent originates from the word antarctic, which comes from Middle French antartique or antarctique (‘opposite to the Arctic’) and, in turn, the Latin antarcticus (‘opposite to the north’). Despite the continent’s remoteness, human activity has a significant effect on it via pollution, ozone depletion, and climate change. Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi). Antarctica (/ænˈtɑːrktɪkə/ ⓘ)note 1 is Earth’s southernmost and least-populated continent.
East Antarctica was at the equator, where seafloor invertebrates and trilobites flourished in the tropical seas. West Antarctica was partially in the Northern Hemisphere, and during the time, large amounts of sandstones, limestones, and shales were deposited. For a large proportion of the Phanerozoic, Antarctica had a tropical or temperate climate, and it was covered in forests.
Also, meteorites that fall to Antarctica are preserved in ice for a long time. Illustration of NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2), a mission to measure the changing height of Earth’s ice. Using ICESat, NASA can measure changes in size of Antarctica’s ice sheets. They also want to know how changes in Antarctic ice might affect Earth’s climate.
