This report provides an overview of contemporary scholarship on the political geographies of oceans. While oceans were overlooked for many years as theories of sovereignty, territory, and borders focused on terrestrial politics, the significant impact of climate change resulted in a new focus on the role oceans place in global environmental and political systems. At the same time, the enclosure of over 40 percent of the oceans as territorial seas, exclusive economic zones, and extended continental shelves through the Convention on the Law of the Sea produced burgeoning literature on maritime borders and conflicts. The report proposes the concept of blue geopolitics to capture an oceanic turn in political geography theories.
