Introduction
Background
Speculation over the existence of a "southern land" was confirmed in the early 1820s when British and American commercial operators and British and Russian national expeditions began exploring the Antarctic Peninsula region and other areas south of the Antarctic Circle. In 1840, it was finally established that Antarctica was indeed a continent and not merely a group of islands or an area of ocean. Several exploration "firsts" were achieved in the early 20th century, but the area saw little human activity. Following World War II, however, the continent experienced an upsurge in scientific research. A number of countries have set up a range of year-round and seasonal stations, camps, and refuges to support scientific research in Antarctica. Seven have made territorial claims, with two maintaining the basis for a claim, but most countries do not recognize these claims. In order to form a legal framework for countries' activities on the continent, an Antarctic Treaty was negotiated that neither denies nor recognizes existing territorial claims; it was signed in 1959 and entered into force in 1961. Also relevant to Antarctic governance are the Environmental Protocol to the Antarctic Treaty and the Convention on the Conservation of Antarctic Marine Living Resources.

Area
land
14.2 million sq km (285,000 sq km ice-free, 13.915 million sq km ice-covered) (est.)
total
14.2 million sq km
Climate
the driest, windiest, and coldest continent on the planet; extreme low temperatures fluctuate based on latitude, elevation, and proximity to the ocean; East Antarctica experiences lower temperatures than West Antarctica due to its greater elevation; the Antarctic Peninsula exhibits the most temperate climate; January sees higher temperatures along the coast, averaging just below freezing; summers are marked by continuous daylight, while winters feature uninterrupted darkness; a persistent high-pressure system over the interior leads to dry air that results in minimal cloud formation
Terrain
composed of approximately 99% thick continental ice sheet and 1% barren rock, with average heights ranging from 2,000 to 4,000 m; mountain ranges can reach nearly 5,000 m; ice-free coastal regions include sections of southern Victoria Land, Wilkes Land, the Antarctic Peninsula, and parts of Ross Island near McMurdo Sound; glaciers create ice shelves along about half of the coastline, with floating ice shelves making up 11% of the continent's area

Maritime claims
Australia, Chile, and Argentina assert Exclusive Economic Zone (EEZ) rights or similar claims extending 200 nm seaward from their continental claims, but these zones, like the territorial claims themselves, are not recognized by other nations; 22 out of 29 consultative parties to the Antarctic Treaty have not made territorial claims in Antarctica, while Russia and the United States have retained the right to do so, and no new claims can be established by any country
Natural hazards
katabatic winds, driven by gravity, flow from the elevated interior towards the coast; frequent blizzards occur at the base of the plateau; cyclonic storms develop over the ocean and progress clockwise along the coast; large icebergs may break off from the ice shelf
volcanism: volcanic activity is present on Deception Island and in isolated regions of West Antarctica; other seismic activities are rare and generally weak
Geography - note
the coldest, windiest, highest (on average), and driest continent; during the summer months, the South Pole receives more solar radiation than the equator does in an equivalent timeframe
largely uninhabitable, with 99% of its land area covered by the Antarctic ice sheet, the largest single mass of ice on Earth; it spans an area of 14 million sq km (5.4 million sq mi) and holds 26.5 million cu km (6.4 million cu mi) of ice, which accounts for nearly 62% of the planet's fresh water
Natural resources
iron ore, chromium, copper, gold, nickel, platinum and various other minerals, along with coal and hydrocarbons, have been discovered in small, noncommercial quantities; the Environmental Protocol to the Antarctic Treaty prohibits mineral exploitation except for scientific purposes; krill, icefish, toothfish, and crab have been harvested by commercial fisheries, which are regulated by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)

People & Society
Population
There are no permanent residents, although personnel are stationed at both year-round and seasonal research facilities during the summer months.
Note: A total of 56 nations ratified the Antarctic Treaty in 1959; among these, 30 nations maintain a combination of seasonal (summer) and year-round research facilities on the continent and its adjacent islands. The population fluctuates from around 5,000 during the summer to about 1,100 in winter, with approximately 1,000 support staff positioned on nearby vessels.
As of 2024, the peak summer (December-February) capacity for scientific stations reaches a maximum of 4,713 individuals; with the following allocations: Argentina 425, Australia 238, Belarus 15, Belgium 55, Brazil 64, Bulgaria 25, Chile 375, China 164, Czechia 32, Ecuador 35, Finland 16, France 136, jointly operated by France and Italy 70, Germany 60, India 72, Italy 150, Japan 130, South Korea 158, New Zealand 85, Norway 60, Peru 30, Poland 41, Russia 211, South Africa 80, Spain 79, Sweden 16, Ukraine 15, United Kingdom 315, United States 1,495, Uruguay 66 (2024)
During the winter months (June-August), the maximum capacity of scientific stations is 1,056; with the following breakdown: Argentina 221, Australia 52, Brazil 15, Chile 114, China 32, France 24, jointly operated by France and Italy 13, Germany 9, India 48, Japan 40, Netherlands 10, South Korea 25, New Zealand 11, Norway 7, Poland 16, Russia 125, South Africa 15, Ukraine 12, United Kingdom 44, United States 215, Uruguay 8 (2024)
Environment
Climate
Antarctica is recognized as the coldest, most windy, and driest continent on the planet; extreme low temperatures fluctuate based on factors such as latitude, elevation, and proximity to the ocean; the eastern region of Antarctica experiences lower temperatures than the western region due to its greater altitude; the Antarctic Peninsula enjoys the most temperate climate; during January, coastal regions see elevated temperatures that usually remain slightly below freezing; summers are characterized by unending daylight, whereas winters are marked by continuous darkness; a persistent high-pressure system over the interior generates dry, descending air, leading to minimal cloud formation.

Flag
description: two horizontal stripes of navy blue and white, featuring a stylized white peak at the center; this peak casts a navy shadow resembling a compass arrow pointing south
meaning: the stripes symbolize the extended daylight and darkness experienced at Antarctica's extreme latitude; the compass arrow pays tribute to the continent's history of exploration; collectively, the peak and the arrow form a diamond shape, representing the aspiration that Antarctica will persist as a hub of peace, discovery, and collaboration
history: the flag is not official; designed in 2018, the True South flag has rapidly gained popularity due to its straightforward yet refined design, and has been adopted by national Antarctic programs, nonprofit organizations focused on Antarctica, and expedition teams.
Country name
etymology
the name is derived from two Greek terms, anti and arktikos, which translate to "opposite to the Arctic" or "opposite to the north."
