Coasts and the sea floor of the northern Adriatic

Western and eastern coast of the northern Adriatic are substantially different. Along the western and north-western side (west from Isonzo River mouth) prevail accumulation type of the coast, developed in recent clastic terrigenous material, whereas along the eastern side (Istria, Kvarner area up to Zadar) erosional type of the coast developed in older carbonate rocks prevails. Likewise, sea-bottom morphology, and sediment type significantly differ offshore of these coasts. Northern from the Ancona – Zadar joint line, in the open part, water depth does not exceed 80 m, sea bottom is very flat, with gentle gradient, and there is a relatively regular change in sediment types from the shore towards the open sea. The channel area of the northern Adriatic is quite specific, with substantial changes in water depth, and depths over 100 m (up to 125 m) are common. Large part of the bottom is devoid of sediment cover, but in some depressions (Rijeka Bay), large accumulation of fine-grained recent and subrecent sediment is found.
