Abstract

A large number of surficial sediment samples (75 grab samples, one boomerang core, four box cores) as well as primary productivity measurements have been used to estimate the rates of sediment accumulation in the Sea of Marmara; using an empirical expression for the relationship between surface productivity and organic carbon content of the sediment (MOLLER-SUESS formula). It was found that calculated low sedimentation rates occurred on the inner southern Marmara shelf (ave. 8 cm 1000 y-1) where the primary production was relatively high (ave. 161 gC m-2 y-1); and vice versa, high sedimentation rates were calculated for the southwestern shelf (123 cm 1000 y-1), an area with very low primary productivity (64 gC m-2 y-1). This discrepancy among the values, is probably due to the combined effects of the distinctive and peculiar oceanography of the Sea of Marmara (well stratified flow, strong horizontal transport, and varying conditions for mineralization of organic matter etc.).
