The Antarctic Treaty that presently holds national land claims at abeyance expired in 1991 and was replaced by the Wellington Agreement.?

The Antarctic Treaty, which originally came into force in 1961, established a framework for international cooperation in Antarctica and held territorial claims in abeyance, effectively preventing new claims and military activity. The Wellington Agreement, signed in 1991, extended the treaty's principles but also allowed for increased scientific collaboration and the potential for resource exploration under specific regulations. However, the core tenets of the Antarctic Treaty remain intact, ensuring that the continent is used for peaceful purposes and scientific research. The treaty and its extensions continue to play a crucial role in preserving Antarctica's unique environment and promoting international cooperation.
