AbstractThe innermost JO km of the South Shore coast is described, showing that both bedrock and surficial geology are a continuation of that seen on land. The offshore geomorphology is essentially an extension of the Maritime peneplane, which has been modified to produce overdeepened basins, particularly in granites. The bedrock surface is cut by sinuous, discontinuous, and anostomosing channels up to 60 m deep. A comprehensive account of late Wisconsinan and early Holocene stratigraphy and sedimentation in this coastal and inner shelf environment has been presented based on seismic profiles and the detailed study of sediments and fauna in 20 piston cores. Although most sediment is derived through the erosion of till cliffs, the Holocene sediment budget suggests that much of the observed nearshore sand must have moved shorewards with the Holocene transgression .
