Abstract

The Çınarcık Basin, the deepest point of the sea at 1270 m, is an important area for the accumulation and preservation of sediments and serves a natural archive for environmental change. In this study, unlike previous studies, short-term sedimentation trends in the basin are presented for the last century. To establish a reliable 210Pb chronology, CRS and CIC Models were applied to process the 210Pb data and validation was done from records of fallout 137Cs. Models CRS and CIC were used because the profile distribution of lead does not decay exponentially. The mean sedimentation rates obtained from 210Pb dating were calculated as 0.36 cmy−1 (CRS) and 0.39 cmy−1 (CIC). 137Cs dating indicated rates of 0.39 cmy−1 at 14 cm depth (1986) and 0.33 cmy−1 at 19 cm depth (1963). In parallel with the developing industry in the region, sediment accumulation rates have shown an increasing trend in the last three decades.
