This book initiates a conversation about blue ecocriticism: critical, ethical, cultural, and political positions that emerge from oceanic or aquatic frames of mind rather than traditional land-based approaches. Ecocriticism has rapidly become not only a disciplinary legitimate critical form but also one of the most dynamic, active criticisms to emerge in recent times. However, even in its institutional success, ecocriticism has exemplified an "ocean deficit." That is, ecocriticism has thus far primarily been a land-based criticism stranded on a liquid planet. Blue Ecocriticism and the Oceanic Imperative contributes to efforts to overcome ecocriticism’s "ocean-deficit." The chapters explore a vast archive of oceanic literature, visual art, television and film, games, theory, and criticism. By examining the relationships between these representations of ocean and cultural imaginaries, Blue Ecocriticism works to unmoor ecocriticism from its land-based anchors.This book aims to simultaneously advance blue ecocriticism as an intellectual pursuit within the environmental humanities and to advocate for ocean conservation as derivative of that pursuit.
