Oceanography 316 2 J^^'AP". 15' Index map of the study area with the New Jersey coastline inset for regional setting. The bathymetric contour lines are in fathoms. terms of spacing and height (). A small-scale ridge system is super- imposed on a large system. The latter appears to be impressed onto a broad shoal-retreat massif, a constructional feature resulting from the retreat of a littoral drift depositional center associated with a retreating estuary mouth (Swift, 1973). The ridge spacing of the larger ridge system averages km with a mean flank dip of °. In addition to the two basic populations a third, smaller system of contrasting sediment bands of negligible relief, has been observed from side-scan records, bottom photographs, and submersible dives (McKinney et al., 1974). Genesis of the ridge topography of the surficial sand sheet on the inner and central continental shelf has remained an enigma to workers since the pioneer work of Veatch and Smith (1939). A historical school of thought suggests that the pronounced undulations of the sandsheet are fluvial or littoral features formed during the lower sea-level stands of the Pleistocene (Veatch and Smith, 1939; Shepard, 1963; Kraft, 1971; McKinney and 449.
