Potential Contributions of IMO Area-Based Shipping Management and Port State Jurisdiction to the Regulation of Ship-Borne Tourism in Antarctica

Abstract

Given the rapid growth of ship-borne tourism in Antarctica, the International Maritime Organization (IMO) area-based management tools (ABMTs) could be a timely and effective contribution to mitigate some of the associated risks. Utilization of IMO ABMTs in Antarctic waters, which constitute high seas, raises several legal and practical issues. The central challenge is how to ensure compliance with IMO measures on the high seas, given the lack of generally accepted coastal state jurisdiction in Antarctica and shortcomings in flag state control. This article addresses these questions and analyzes port state jurisdiction as a potential mechanism to enforce IMO ABMTs in the Antarctic. The article concludes that Antarctic port states have sufficient legal arguments to justify the exercise of jurisdiction in relation to IMO ABMTs, and that significant constraints lie in the economic and political dimensions of regulation rather than in regulation itself.
