Oceanography HEIStOCINE SAND AND OtAVU Figure Erosional retreat of the inner shelf â profile_, and resulting coarse sediment dispersal. shoreface erosion during storm flows and redistribute the sand over the adjacent shelf surface. Although no direct evidence is yet available, such redistribution must occur during periods of intense easterly winds. During such periods water is driven against the coast. The excess pres- sure head may be relieved by means of a downwelling coastal jet whose bottom water sweeps sand down coast and seaward. Circumstantial evidence for such flows occurs in the form of patches of sand-waves (figs. , ), oriented oblique to the coast, which are most clearly defined in early spring, and which tend to be obliterated by the end of summer. During such peak flow events the Bight apex gyre probably does not function, and the flow trends instead west and south through the apex. This spasmodic, high intensity flow field rather than the fair weather flow field is probably responsible for the bedform patterns of figure , which may constitute a time-averaged response to such flows.
