Sediment deposition and accumulation rates determined by sediment trap and Pb-210 isotope methods in the Outer Puck Bay (Baltic Sea)

Two methods in situ sediment trap experiments and an isotopic method based on measurements of Pb-210 activities in the sediment cores taken near the traps were applied for determining sediment deposition and sediment accumulation rates in the eastern part of Puck Bay. The sediment deposition rate (1.67 mm year(-1)) based on the in situ measurement was comparable with the sediment accumulation rate calculated using the Constant Flux:Constant Sedimentation Rate model for the isotopic method. The age of the sediment layers was determined with the Constant Rate of Supply model; the deepest layers had accumulated around 1900.
