Abstract
It is proposed that sites belonging to Early Maritime Archaic Indians (MAI) in Newfoundland were located on 6000 to 9000-year-old shorelines that are now submerged on the seabed in 10 to 30 m water depths. We have developed a research plan to prospect for these ancient sites that incorporates: (i) a computer-modelled simulation of relative sea-level (RSL) changes, constrained by geological data, that predicts the depth of submerged shorelines at specified time intervals around the coast; (ii) a high resolution seafloor map of selected study areas (e.g. Fogo Island, Burgeo), which in combination with the RSL data, will generate a series of reconstructed shorelines charting the prehistoric evolution of the coast; (iii) targeted sub-bottom profiler and coring surveys to map the geophysical signatures of palaeo ‘land-surfaces’ (e.g. freshwater lake basins, buried bogs and lagoons, gravel beaches and terraces); (iv) ground-truthing and dating of these terrestrial environments to refine the RSL model and to improve our interpretation of the geophysical record; (v) integration of sub-bottom data with seabed palaeogeographic reconstructions to produce a fully 3-dimensional evolutionary model of the maritime landscape; (vi) application of a predictive model, based on landscape attributes of Late MAI sites in Newfoundland, to classify the archaeological potential of these maritime landscapes; and (vii) remote testing (e.g. geophysics, video) and sampling (e.g. grab sampling, coring) of high potential sites. These research steps will be further described and illustrated in the presentation.
