Summary/Abstract
Ocean upwelling pipes are used to upwell nutrient-rich deeper waters in order to fertilize the surface ocean. This article addresses whether international legal rules exist governing the deployment of ocean pipes and which states are entitled to exercise jurisdiction over these objects. Taking into account the need to avoid user conflicts and unauthorized deployment of upwelling pipes in marine areas under the jurisdiction of third states, the article advocates the development of nonbinding guidelines that would implement the general terms of the United Nations Convention on the Law of the Sea.
