Sediment accumulation rates were estimated from the vertical distribution of excess Pb-210 in sediment cores collected at six stations in the Gokova Bay near the heavily industrialized Turkish Coastal zone of the Aegean Sea. Total Pb-210 was determined by measuring Po-210 activities. The sediment accumulation rates were calculated to vary from 0.32 +/- 0.01 cm yr(-1) (0.17 +/- 0.01 g cm(-2) yr(-1)) to 1.92 +/- 0.20 cm yr(-1) (1.13 +/- 0.10 g cm(-2) yr(-1)). The unsupported Pb-210 flux was calculated from the accumulated dry matter of the examined slices and their unsupported Pb-210 concentrations. The flux of unsupported Pb-210 varies between 62 +/- 5 and 105 +/- 8 Bq m(-2) yr(-1). The average depositional flux was found to be considerably higher for cores from the Mediterranean.
