This talk will discuss elements of a research project that explores the evolution of the law of the sea over the course of the 20th century It will focus on the emergence of the seabed as an area of political, economic and technological interest, and trace its subjection to national and international regimes. Calling attention to the legally constructed imaginary of the seabed as a space distinct from the above water, the talk will re-examine views of both the ocean and the law, which are commonly held, and presented as natural and therefore necessary. Suggesting instead a greater focus on the contingencies and false contingencies informing the development of the law, the talk will join a small but growing literature on the unnatural history of the sea.
