The maritime part of the region constitutes the area of application of the international Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR), where for technical reasons the Convention uses an approximation of the Convergence line by means of a line joining specified points along parallels of latitude and meridians of longitude. The implementation of the Convention is managed through an international Commission headquartered in Hobart, Australia, by an efficient system of annual fishing quotas, licenses and international inspectors on the fishing vessels, as well as satellite surveillance.
Most of the Antarctic region is situated south of 60°S latitude parallel, and is governed in accordance with the international legal regime of the Antarctic Treaty System. The Treaty area covers the continent itself and its immediately adjacent islands, as well as the archipelagos of the South Orkney Islands, South Shetland Islands, Peter I Island, Scott Island and Balleny Islands.
The islands situated between 60°S latitude parallel to the south and the Antarctic Convergence to the north, and their respective 200-nautical-mile (370 km) exclusive economic zones fall under the national jurisdiction of the countries that possess them: South Georgia and the South Sandwich Islands (United Kingdom; also an EU Overseas territory), Bouvet Island (Norway), and Heard and McDonald Islands (Australia).
Kerguelen Islands (France; also an EU Overseas territory) are situated in the Antarctic Convergence area, while the Falkland Islands, Isla de los Estados, Hornos Island with Cape Horn, Diego Ramírez Islands, Campbell Island, Macquarie Island, Amsterdam and Saint Paul Islands, Crozet Islands, Prince Edward Islands, and Gough Island and Tristan da Cunha group remain north of the Convergence and thus outside the Antarctic region.
