Resolving the un-delimited Arctic boundary between Canada and the United States in the Beaufort Sea using a law-and-science approach

The paper discusses the Canada-US boundary dispute in the Beaufort Sea from a combined legal and geo-scientific perspective and by reference to the latest boundary delimitation jurisprudence and 4D-technology.

Fewer than half of the 500 or so potential maritime boundaries in the world have been agreed, creating uncertainty not only for the coastal States involved but also for their investors active in the offshore oil and gas industry. The complex process of agreeing and fixing boundaries or of making provisional arrangements can be time-consuming and expensive but once agreed can significantly contribute to the economic wealth of the affected countries. Disputes over maritime boundaries regularly flare up around the world and sometimes result in skirmishes. Coastal States with competing claims to maritime areas routinely offer and award oil concessions in disputed waters without the investors taking blocks being fully aware of the underlying inter-State dispute and the risks presented by an un-delimited boundary, especially one featuring straddling deposits. Indeed, maritime boundary disputes form a misunderstood and frequently overlooked area of investment risk management in the energy sector.
