While most historians have treated the sea as a surface or a void, the history of science is well positioned to draw the ocean itself into history. The contributors to this Focus section build on the modest existing tradition of history of oceanography and extend that tradition to demonstrate both the insights to be gained by studying oceans historically and the critical role that the history of science should play in future environmental history of the ocean.

In 1902, eight northern European nations formed the International Council for the Exploration of the Sea (ICES). A turn-of-the-century international movement created opportunities, funding, and political support for marine science. This paper uses ICES as a lens for examining international cooperation, and shows how its sponsors benefited from the intersection of internationalist ideals, national interest, and the characteristics of the marine environment. Marine science is then compared to other field sciences to explore how these three factors promoted internationalism in science (...) more generally. (shrink)
