| | International cooperation in the IGY stimulated the Antarctic Treaty [http://www.state.gov/t/ac/trt/4700.htm], signed by the 12 Antarctic IGY nations at Washington, D.C., in 1959 and entered into force in 1961. The treaty establishes a legal framework for the area south of 60°S, which includes all of Antarctica. There are two types of Antarctic Treaty parties. Consultative nations, now 26 in number, are empowered to meet periodically and to influence operation of the treaty. Acceding nations, of which there now are 17, agree to abide by the treaty, but, not being among the original signatories and not having substantial programs in Antarctica, do not participate in the consultative process. | | International cooperation in the IGY stimulated the Antarctic Treaty [http://www.state.gov/t/ac/trt/4700.htm], signed by the 12 Antarctic IGY nations at Washington, D.C., in 1959 and entered into force in 1961.
