Sediment Distribution in Southwestern Delaware Bay.
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.
