During the intensification of research activities in the Southern Ocean in recent years, both at national levels and through international cooperation in such projects as BIOMASS with its FIBEX and SIBEX phases, the need was felt increasingly for closer collaboration between biologists, meteorologists, and oceanographers in the study of the interaction between the atmospheric forces, the water masses, and the living resources. Better knowledge in this regard is not only of scientific interest but also of practical importance, especially for the management of the resources and the protection of the Antarctic marine ecosystem. As a follow-up on a recommendation by the IOC Program Group for the Southern Oceans made in March 1983, the Intergovernmental Oceanographic Commission organized a meeting of experts on oceanography related to the dynamics of the Antarctic ecosystems. During this meeting, held in Kiel, Federal Republic of Ger many, in May 1984, biologists and oceanographers involved in BIOMASS activities met with the oceanographers of SCOR Working Group 74 to discuss ways and means for additional physical and chemical observations in the oceanographic research within BIOMASS. It was the time when large fluctuations in the distribution of krill with subsequent detrimental effects on predator species dependent on krill had just been observed, and the question arose whether this was possibly the result of changes in the Antarctic water circulation.

Antarctica, one of the world's last great wildernesses, presents special challenges for international law. Fears that Antarctica would become a front in the Cold War catalysed agreement on the 1959 Antarctic Treaty which neither legitimised nor challenged the existing sovereign claims to the continent. The unique Antarctic Treaty System has provided the foundation for peaceful, harmonious and effective governance. There are, however, new anxieties about the frozen continent and the Southern Ocean. Antarctica already feels the effects of climate change and ocean acidification. Claimant states assert rights to the Antarctic continental shelf and interest in Antarctic resources grows. Tourism brings new environmental and safety risks. China and other powers are increasing their activities, with some questioning the consensus of the 'Antarctic club'. Security concerns are increasingly discussed, despite Antarctica's dedication to peaceful purposes. This book brings together the main primary international materials concerning the regulation and governance of Antarctica, including multilateral and bilateral treaties, United Nations materials, 'soft laws' and judicial decisions. It covers the spectrum of Antarctic issues from environmental protection to scientific cooperation to tourism. As it shows, Antarctic law has constantly adapted to meet new challenges and is a sophisticated, inclusive, dynamic and responsive regime.
