Polish Baltic Sea coast - Opis:
- Morphology of sea bottom of the Władysławowo area, from Karwia to Chałupy, has been studied based on the detailed digital bathymetric map prepared in a scale of 1:25 000 with isobaths every 0.25 m. A significant differentiation of the bottom relief has been observed, with the level changes up to 1-3 metres, mostly connected with the occurrence of specific systems of ridges and runnels. They are probably partly relict forms (fluvial and/or coastal?), changed to certain degree during the rapid stage of the Litorina transgression, and in partly forms created by the recent waves. Several types of the sea bottom surface, differing in pattern of morphological forms, have been recognised within inshore, near shore, and open sea (above 16 m depths) areas. The full knowledge of the origin and development of these relief forms requires further specialised research, currently carried out. Nonetheless, the already obtained picture of the sea bottom relief indicates an intensified abrasion of the offshore sea bottom, and an intensive, irreversible sweeping out of the sediments from the shore to the open sea, most probably by rip currents, at a distance up to several kilometres from the shore. It is in accordance with the results of a former large-scale (1:500) study of the sea bottom at the test field at Chłapowo, performed with the use of an integrated system of non-invasive and direct methods.
