Abstract
Three Eastern Mediterranean Sea cores containing sediments deposited during the last deglaciation (last 15 ka BP) have been studied for their dinoflagellate cyst content. Detailed AMS dating enabled calculation of cyst influxes. Variations in these influxes can be interpreted in terms of variations in cyst production in surface waters. Information about changes in sea surface temperature, salinity, and nutrient availability during the last deglaciation are derived from previous studies on pollen, planktic and benthic marine foraminifera, stable isotope data, and dinoflagellate cyst abundance data. Correlation between this information and variation in cyst production of individual species provided the ability to relate the cyst production to changes in these environmental variables. The production of Bitectatodinium tepekiense, Spiniferites elongatus, Spiniferites mirabilis and cysts of Protoperidinium species increased with increased nutrient availability. Changes in sea surface temperature influenced the cyst production of Bitectatodinium tepekiense, Spiniferites elongatus and Nematosphaeropsis labyrinthus. Lingulodinium machaerophorum and Spiniferites membranaceus can be produced under extremely high and low salinity levels in sea surface waters.
