Özet
In this study, sediment chronology was determined by using Lead-210 (210Pb) dating models in Gulbahce Bay. Sediment cores were obtained via a gravity core sampler from hydrothermal area and also from reference point and surficial distribution of Polonium-210 (210Po) was investigated in the study area. The average surficial 210Po concentration was relatively higher in hydrothermal area than the reference point. Sedimentation rates in Core reference point (RN) displayed an increase till the 1940’s and a decrease afterwards, sedimentation rates in any core from hydrothermal area did not exhibit regular continuous increase or decrease. The 210Pb fluxes measured from core inventories are close to each other but they are a bit higher than the average mediterranean and mean atmospheric 210Pb flux values. This situation indicates that there are outer contribution to the study area apart from atmospheric precipitation of 210Pb concentration. Average enrichment factors indicating that the sediments have not been co...
