Accumulation rates and sediment deposition in the Goekova Bay in Aegean Region

Sediment accumulation rates were estimated from the vertical distribution of excess ''2''1''0Pb in sediment cores collected at 3 stations in the Goekova Bay Aegean Sea by measuring the α- emission of ''2''1''0Po. The Turkish coastal zone of the Aegean Sea has been heavily industrialized in the last 20 years. The sediment accumulation rates were calculated to vary from 0.21±0.01cm.y''-''1 (0.133±0.01 g.cm''-''2y''-''1) to 0.49±0.05cm.y''-''1 (0.26±0.03 g.cm''-''2y''-''1). The unsupported ''2''1''0Pb flux was calculated from the accumulated dry matter of the examined slices and their unsupported ''2''1''0Pb concentrations. The flux of unsupported ''2''1''0Pb varies between 23±4 and 47±3 Bq.m''-''2y''-''1
