Reluctant collaborators: Argentina and Chile in Antarctica during the International Geophysical Year, 1957–58

Abstract

This paper suggests that Argentine and Chilean participation with the Antarctic section of the International Geophysical Year (IGY) of 1957–58 can be characterized as ‘reluctant collaboration.’ It then reflects on the implications of the nature of South American involvement for the history of the Antarctic section of the IGY, especially as it led to the negotiation of the 1959 Antarctic Treaty. During the initial planning stages of the IGY, both Argentina and Chile worried that proposals for widespread scientific research in the Antarctic continent would interfere with their contested claims to political sovereignty in the region. Yet despite their initial skepticism, Argentina and Chile found themselves swept along by the current of international scientific co-operation of the IGY, which persisted into the Antarctic Treaty negotiations of 1959. Within the limited options available, Chile and Argentina were able to negotiate an outcome that was not altogether unfavorable to their political interests. At the same time, their collaboration helped to legitimize both the IGY and the subsequent Antarctic Treaty.
