| Slowly accumulated (<5 cm kyr(-1)) and rapidly accumulated (5-20 cm kyr(-1)) sediments have been compared to define the initiation and termination times of the most recent sapropel (S1) in the eastern Mediterranean Sea. The Ba/Al ratio has been employed as a more persistent index of productivity than C-org. Accelerator mass spectrometry radiocarbon dating of pelagic foraminifera indicates a maximum duration for increased Ba/Al levels in S1 from similar to 9500-6000 (uncorrected radiocarbon convention years B.P.) in the rapidly accumulated sediments and similar to 9500-5300 years B.P. in the slowly accumulated sediments. This difference is ascribed to bioturbation affecting the slaver accumulated S1 sediments. In the two most rapidly accumulated S1... |
