Abstract : Upward and landward migration of sedimentary environments during the Holocene marine transgression has resulted in complex sediment distribution patterns in southwestern Delaware Bay. Analyses of 'thin-skin' surface samples using CM diagrams (Passega), sediment population analysis (Visher) and bathymetric relationships, indicate major processes contributing to the observed sedimentary distribution pattern: deposition from suspension in quiet water is occurring in Breakwater Harbor; well sorted sand deposits are being formed by the winnowing action of waves on top of the shoals in the open estuary in the northern portion of the study area; and strong tractive currents appear to be the dominant force controlling grain size distribution on The Shears, large shoal areas near the mouth of Delaware Bay.
