The largest estuary in the world, the Gulf of St Lawrence is defined broadly by an ecology that stretches from the upper reaches of the St Lawrence River to the Gulf Stream, and by a web of influences that reach from the heart of the continent to northern Europe. For more than a millennium, the gulf’s strategic location and rich marine resources have made it a destination and a gateway, a cockpit and a crossroads, and a highway and a home. From Vinland the Good to the novels of Lucy Maud Montgomery, the Gulf has haunted the Western imagination. A transborder collaboration between Canadian and American scholars, The Greater Gulf represents the first concerted exploration of the environmental history - marine and terrestrial - of the Gulf of St Lawrence. Contributors tell many histories of a place that has been fished, fought over, explored, and exploited. The essays’ defining themes resonate in today’s charged atmosphere of quickening climate change as they recount stories of resilience played against ecological fragility, resistance at odds with accommodation, considered versus reckless exploitation, and real, imagined, and imposed identities. Reconsidering perceptions about borders and the spaces between and across land and sea, The Greater Gulf draws attention to a central place and part of North Atlantic and North American history.
