Southern Ocean Boundaries and Maritime Claims: Another Antarctic Challenge for the Law of the Sea?

Throughout the life of the 1959 Antarctic Treaty there has been considerable development in the law of the sea. Negotiated following the 1958 First United Nations Conference on the Law of the Sea, at which the customary international law concepts of the territorial sea and continental shelf were codified into treaty law, the law of the sea has since developed through state practice and most importantly through the 1982 United Nations Convention on the Law of the Sea. Whatever the merits of examining the interaction between Antarctica and the law of the sea have been in the past, there is much to suggest that the general significance of such issues is growing, especially as states seek to determine the outer limits of their continental shelf claims and in doing so determine Antarctic baselines. This article examines these issues from a general law of the sea perspective, taking into account the impact of the Antarctic Treaty while reviewing Australian practice in particular.
