This chapter addresses the ways in which ocean space has historically been subject to imagining, and the place of art in creating ocean imaginaries. It considers the artistic engagements with, and interpretations of, ocean space through the works of two artists, Emma Critchley and Mariele Neudecker, and their responses to the effects of technological, ecological and economic exploitation on the oceans. Their oceanic perspectives and fluid practices create encounters and exchanges in an entanglement of virtual data and natural phenomena.
