Environmental change such as global warming and sea level rise is contributing to coastal loss, with approximately 50% of both global and U.S. shorelines in an erosional state. Localized conditions can exceed these estimates, with some U.S. state shorelines having as much as 80% of their coastal areas in retreat. Shoreline erosion and subsidence are inundating terrestrial archeological sites and coastal construction projects and the hard armoring measures to abate these actions can detrimentally impact archeology in these areas. These rising threats require a reassessment of how coastal sites are investigated. The panel discussants will evaluate current methods of investigation for inundated intertidal and foreshore terrestrial sites to propose more effective and replicable modes of survey, site identification, and delineation. The goal is to establish a multidisciplinary consensus towards best practices for archaeological investigations in coastal areas.
