Augmentation of Studies into the Development and Evolution of Sedimentary Structures.

Abstract

Sedimentological studies were conducted in central Eckernfoerde Bay. Sediment is characterized by beds of clay-sized material, with slightly coarser laminations (approx. 10% silt and sand). Excess 234Th activity indicates that mixing is limited to the upper 5 mm of the seabed. Accumulation rates, measured by 210Pb geochronology, range from 5 to over 10 mm/yr. The relatively high accumulation rates and absence of a significant mixed layer in the central bay allow fluctuations of sedimentological processes to be recorded in fine detail. Sediment-transport studies indicate that the laminated bedding is caused by alternating deposition of storm-suspended sediments from adjacent shallow-water areas and fair-weather supply of fine suspended material advected from the open Baltic.
