Most legal thinkers and practitioners view law as fundamentally terrestrial. Indeed, law—in its Eurocentric iteration at least—ultimately imagines itself as beginning and ending on terra firma. Land is perceived as a fully historicized, mapped, and regulated space that stands in stark opposition to the seemingly a-temporal, empty, and unruly sea. This collection traces some of the juridical thinking that has enshrined the land/sea divide into contemporary governmen-tal infrastructures, disciplinary traditions, and regulatory apparatuses, and charts the disastrous implications that such a legal fixation on the land/sea binary has wrought on human and other-than-human lifeworlds. Ultimately, the question we ask here is whether contemporary Western law is capable of pushing beyond its mythical imaginaries and its imperial and colonial legacies—which are arguably founded upon the land/sea binary, among other uxtaposed divides—to correspond with, rather than ignore or attempt to fix, the dynamic and relational nature of oceanic entities.
