A scheme of bathymetric data acquisition for the area of study (location and number of
navigation charts used are shown)
features Palaeogene-Neogene, sandy-clayey sediments preserved from glacial
washout. North of the Sambian Peninsula lies the extensive Curonian-Sambian
Plateau, overlain by a thin cover of Quaternary (moraine) formations.
The coastal area constitutes an inclined surface of erosion-accumulation plain
developed in the moraine and, in some places, in the bedrock; it extends offshore
to the depths of 30-35 m. The Gdansk Deep (a cup-shaped depression with depths
of up to 115 m) is an accumulation plain covered by unconsolidated late- and post-
glacial silts and clays (up to 15-20 m thick). Its slope forms an inclined surface, at
