Contemporary public discourses about the ocean are routinely characterized by scientific and environmentalist narratives that imagine and idealize marine spaces in which humans are absent. In contrast, this collection explores the variety of ways in which people have long made themselves at home at sea, and continue to live intimately with it. In doing so, it brings together both ethnographic and archaeological research – much of it with an explicit Ingoldian approach – on a wide range of geographical areas and historical periods.
