Country Profile: Antarctica

Antarctica is a vast, icy continent located predominantly south of the Antarctic Circle, known for being the coldest, windiest, and driest place on Earth. It is largely uninhabitable, with no permanent inhabitants, although thousands of scientists and support staff reside at research stations during peak summer months. The economy is primarily driven by scientific research, and governance is established through the Antarctic Treaty, which ensures the continent is utilized for peaceful purposes and prohibits military activities. The region is also notable for its environmental issues, particularly concerning ozone depletion and ice loss.

Geography

Antarctica, the fifth-largest continent, encompasses an area of 14.2 million sq km, approximately 1.5 times the size of the US. The continent's geographic features include a mean elevation of 2,300 m and an ice sheet covering 99% of its land area. The harsh climate varies significantly, with East Antarctica being colder due to its elevation, while the Antarctic Peninsula experiences the most moderate conditions.

17,968 km of coastline.
99% of land covered by ice.
Vinson Massif is the highest point at 4,892 m.

People and Society

Antarctica has no permanent residents; however, its population fluctuates with research activities. During the summer months, around 5,000 people are present due to various seasonal research stations, while winter sees this number drop to approximately 1,100. The Antarctic Treaty, signed by 56 countries in 1959, governs these research activities.

Peak summer population capacity (2024): 4,713.
Winter population capacity (2024): 1,056.
Major contributing countries to the summer population include the United States (1,495) and Argentina (425).

Environment

Antarctica faces significant environmental challenges, primarily characterized by the size of its ozone hole and ice loss. The continent's extreme climate contributes to its role as a critical area for scientific research related to climate change.

15,000 metric tonnes of CO2 emissions estimated for 2023.
0% of land used for agriculture (2018 estimate).
Notable environmental protocols were enacted in 1991 to protect the region.

Government

Antarctica operates under the Antarctic Treaty, which promotes scientific cooperation and bans military activities. This treaty has been effective since 1961 and imposes restrictions on territorial claims while allowing for inspections by member nations. There are currently 58 member nations of the treaty, facilitating international governance.

The treaty covers all land south of 60° south latitude.
Decisions are made by consensus during annual meetings.
The Autonomous Antarctic Treaty Secretariat was established in 2004.

Military and Security

Military activities in Antarctica are prohibited by the Antarctic Treaty, which disallows the establishment of military bases or weapon testing. Military personnel may assist with peaceful research efforts, aligning with the treaty's focus on scientific cooperation.

The treaty went into effect in 1961.
No military bases or fortifications are permitted.

Energy

Antarctica's energy consumption is minimal due to its lack of a permanent population and industrial activity. Most energy use is related to scientific research and support operations.

79 bbl/day of refined petroleum consumption (2023 estimate).
2,000 metric tons of coal imported in 2023.

Transportation

Transportation infrastructure in Antarctica is primarily geared toward supporting scientific missions. The continent has 31 airports and 8 ports, facilitating the movement of personnel and supplies.

Planned number of airports by 2025: 31.
Total ports in operation as of 2024: 8.

Communications

Communication in Antarctica is facilitated by satellite technology, and internet access is almost universal among research personnel.

100% of the population reported being internet users as of 2021.
