Country Profile: Antarctica

Antarctica is a unique continent located mostly south of the Antarctic Circle, characterized by its extreme cold, vast ice sheets, and a largely uninhabitable landscape. It has no permanent inhabitants, with a seasonal population comprised of scientists and support staff that fluctuates between approximately 1,100 in winter and 5,000 in summer. Governance of Antarctica is structured around the Antarctic Treaty, initially signed in 1959, which promotes scientific research and international cooperation while banning military activity. The economy is primarily focused on scientific activities, with limited resource extraction, and the environment faces challenges such as climate change and ozone depletion.

Geography

Antarctica is the fifth-largest continent, covering an area of 14.2 million square kilometers, predominantly covered by ice. The terrain is marked by a thick continental ice sheet, with some regions of ice-free land primarily along the coast. Its climate is extremely harsh, being the coldest, driest, and windiest continent on Earth, with significant temperature variation based on location and elevation.

99% of the continent is covered by the Antarctic ice sheet, the largest single mass of ice on Earth.
The highest point is Vinson Massif at 4,892 m.
The lowest point is Denman Glacier, more than 3,500 m below sea level.

People and Society

Antarctica has no permanent population; however, various countries operate research stations that host scientists and support personnel. During the summer months, the population can swell to around 5,000, while winter populations drop to about 1,100. As of 2024, research stations see a peak capacity of 4,713 personnel in summer and 1,056 in winter.

56 countries have signed the Antarctic Treaty.
The United States hosts the most personnel in summer, with 1,495 individuals.
The peak summer population includes 30 nations operating research stations.

Government

Antarctica is governed by the Antarctic Treaty, which emphasizes peaceful use and scientific research while banning military activity. Decisions regarding governance are made by consensus among member nations during annual meetings. This legal framework also includes environmental protocols aimed at protecting the continent’s ecosystem.

The Antarctic Treaty was signed in 1959 and has been in force since 1961.
There are 58 member nations as of December 2024.
The Treaty allows for inspections of stations and facilities by member countries.

Energy

Antarctica consumes limited energy resources primarily for scientific operations. The refined petroleum consumption is minimal, reflecting the continent’s focus on research rather than industrial activities.

Refined petroleum consumption is approximately 79 barrels per day (2023 est.).
2,000 metric tons of coal were imported in 2023.

Environment

Antarctica's environment is facing significant challenges, including ice loss and a persistent ozone hole that affects the continent. The extreme cold and dry climate contributes to unique environmental conditions that necessitate strict protections against contamination and resource exploitation.

Total carbon dioxide emissions were around 15,000 metric tonnes in 2023.
0% of the land is used for agriculture as of 2018.

Transportation

Transportation in Antarctica is largely facilitated through air and sea, with numerous research stations equipped to support these operations. As of 2025, there are 31 airports and 8 ports on the continent, primarily used for research and supply activities.

31 airports are operational by 2025.
There are 5 heliports available as of 2025.
Key ports include McMurdo Station and Port Lockroy.

Communications

Antarctica has a fully connected infrastructure for communications, with internet access available at all research stations. The continent's internet country code is ".aq."

100% of the population had internet access as of 2021.
