Abstract

Thirteen gravity cores taken off northern Greece contain the S1 sapropel, as a single layer in cores from water depths <250 m and usually as a double layer in cores from deeper water. Total thickness of the sapropel layer is proportional to thickness of sediment between the sapropel and an 18 ka seismic marker. These observations suggest that the sapropel is not diachronous. Five AMS radiocarbon dates of molluscs and echinoderms indicate an age of 6.4–9.2 ka for the S1 sapropel, considerably younger than previous age estimates in the northern Aegean Sea of 9–13 ka, which were based on bulk sample dating techniques.
