Goals of the Antarctic Treaty System

Signed in 1959 (effective 1961), the Antarctic Treaty establishes the continent as a zone of peace and science. Its core objectives:

• Peaceful Use: Prohibits military bases, maneuvers, weapons testing.
• Scientific Freedom: Promotes international research cooperation; data sharing.
• Environmental Protection: Bans nuclear explosions & radioactive waste; later protocols (Madrid Protocol, 1991) designate Antarctica a "natural reserve, devoted to peace and science," banning mineral mining.
• Sovereignty Neutrality: Freezes territorial claims; no new claims allowed.
• Inspection Regime: Open access for treaty parties to inspect all stations.

54 nations are parties; 29 have consultative (voting) status. A model of Cold War diplomacy enduring into the 21st century.
