Major events of human prehistory such as the post-glacial recolonisation of Northern Europe and the spread of agriculture through the Mediterranean took place on landscapes that are now, at least partially, underwater. Large parts of this submerged terrain are accessible to divers and can be investigated archaeologically. Prehistoric underwater research has emerged in recent decades as a distinct sub-discipline, developing approaches and methodologies that can be applied in coastal regions worldwide. As a result, there is growing awareness of the potential for underwater archaeology to transform our ideas about the course of prehistory. This volume examines existing practice and new developments in the field of submerged prehistoric landscape research. The 25 peer-reviewed contributions from leading authors cover the results of recent research on three continents andthe application of methodologies and techniques for site discovery, investigation and interpretation.
