HOLOCENE SEA SURFACE SALINITY CHANGES IN THE NORTHERN AEGEAN SEA: EVIDENCE FROM SIZE VARIATIONS OF EMILIANIA HUXLEYI-COCCOLITHS
Three major SSS events can be identified at about 8.2, 8.7 kyr, and between 9.6 to 7.0 kyr which correspond to the 8.2 kyr Event, the Black Sea outflow into the AS and the sapropel S1 formation respectively. The most rapid salinity increase of >1 occurred during the short-lived 8.2 kyr cold event, which was most likely triggered by a melt-water related perturbation of the Atlantic Meridional Overturning and associated decrease of ocean heat transport to the North Atlantic. The onset of the Black Sea outflow can be identified at 8.7 kyr which is marked by decreasing SSS of >1. In contrast, the onset and end of the sapropel formation is characterized by a gradual change in SSS.
