Comment:

The granulometric sediment composition of the superficial layer of a fine sand site 30 km west of the island of Sylt in 20 m water depth was studied annulally in autumn by a minimum of six cores (mechanical dry sieving). In three years (1993, 1994, and 1996), temporal resolution was increased by additional sampling in spring. Spatial variability on a km-scale was studied from 1992 to 1996 by three additional sites adjoining north to the continuiously sampled area.
