The exit of the Strait of Çanakkale into the North Aegean Sea was explored by high-resolution shallow seismic method. The morphological and structural elements of the area were examined. The stratigraphic units were delineated. The role of a buried Miocene sill at the 9-km west part of the strait on the paleoceanographic evolution of the area has been discussed. An approximate paleoceanographic coastline representing the time 135-150 ky B.P. when the sea level was 130 m lower than it is today was reconstructed.
