A combination of reconstruction of the former coastline and field survey of previously unrecorded sites provides the basis for the study of the maritime landscape and maritime activities around Portrush on the north coast of Ireland during the Mesolithic period. Movements in relative sea-level and geological events indicate significant change in environment and availability of resources, particularly flint, for the coastal community. Evidence suggests that most Early Mesolithic material, deposited close to the then shoreline, is presently under water. Remnants of the Late Mesolithic are fast disappearing as coastal erosion continues.
