Abstract
The paper reports 134Cs, 137Cs and 40K radionuclide concentrations in macroalgae and sediment samples collected from the Bosphorus of Turkey. They were determined during the period of 1989-1990. The highest accumulation of 137Cs radionuclide was found in Enteromorpha linza species. The 134Cs and 137Cs levels reached peak values in all sediment samples collected from Sarıyer. The results showed that the Sarıyer station was the most contaminated among all the stations of the Bosphorus.

Abstract
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.
