“…The archaeological implications of these changes have been recognised for a long time and early work used simple maps of present-day bathymetry to explore their impact on a range of issues, including the varying visibility of marine resources at different periods in the Pleistocene, the differential preservation of coastal archaeological sites, the constraints on human dispersal imposed by the creation and submergence of land bridges, changes in shoreline ecology, and alterations more generally in the palaeoeconomic potential of coastlines following the extension or contraction of coastal territory (Bailey, 1978(Bailey, , 1983Richardson, 1978;Shackleton et al, 1984;Shackleton and Van Andel, 1986). Early attempts were also made to explore the nature of the submerged landscape in more detail using remote sensing techniques (Van Andel and Lianos, 1984a,b), and to excavate underwater sites, most famously the Mesolithic site of Tybrind Vig in Denmark (Andersen, 1980, see also Masters and Flemming, 1983).…”
