Barrier island on the Gulfs Reef (Puck Bay, Polish Baltic Coast)

Abstract

The paper deals with structure and stages of development of a short-lasting barrier island in the Puck Bay on the Baltic Coast. This form. originated exclusively from wave processes acting together with changes in level of the Puck Bay waters, related to wind and atmospheric pressure influence, and without a contribution of longshore currents. Its deeper part, formed by waves under constant submersion conditions appears to be structurally different from surfacial parts, which are genetically related to action of waves and surf on the emerging barrier. Morphology, structure, and ripple marks formed along the inner side of the barrier island ·appear very dose to those of tidal flat environment.
