During summer, Antarctica is on the side of Earth tilted toward the sun and is in constant sunlight. Antarctica has six months of daylight in its summer and six months of darkness in its winter. There are companies in South America that have vacations to Antarctica, so people pay to go there on a ship. Most live at national science stations on the coast.
The ice sheet flows outward under its own weight, feeding floating ice shelves such as Ross and Filchner-Ronne. This clarifies mapping and science while aligning with how oceanographers trace currents like the Antarctic Circumpolar 7Reels Casino Current. The continent is encircled by the Southern Ocean, now formally recognized by major authorities, including NOAA and the International Hydrographic Organization (IHO). Antarctica’s highest peak is Mount Vinson at 16,050 feet (4,892 meters) in the Ellsworth Mountains; its coldest reliably measured air temperature is −128.6°F (−89.2°C) at Vostok Station on 21 July 1983. Antarctica is the highest, driest, and coldest continent, a polar desert covered by an ice sheet averaging about 1.34 miles (2.16 kilometers) thick. Rising sea level from melting ice sheets can create dangerous conditions for people living close to the ocean.
In the present, sovereignty over regions of Antarctica is claimed by seven different countries. Several countries with research stations in Antarctica allow their citizens stationed in the continent to vote in their elections. The treaty set aside Antarctica as a scientific preserve and established freedom of scientific investigation and environmental protection. Countries can participate in decision-making if they can demonstrate that they do significant research on Antarctica; as of 2022update, 29 countries have this ‘consultative status’. Antarctica is defined as all land and ice shelves south of 60° S for the purposes of the Treaty System. Antarctica’s status is regulated by the 1959 Antarctic Treaty and other related agreements, collectively called the Antarctic Treaty System.
