Holocene seasonal sea-surface temperature variations in the southern Adriatic Sea inferred from a multiproxy approach. In: Journal of Quaternary Science, vol. 18 (8) pp. 723 - 732. John Wiley & Sons Ltd, 2003.
Holocene cooling events have been reconstructed for the southern Adriatic Sea (central Mediterranean) by means of analyses of organic walled dinoflagellate cysts, planktonic foraminifera, oxygen isotopes, calcareous nanoplankton, alkenones and pollen from a sediment core. Two cooling events have been detected, during which sea-surface temperatures (SSTs) were ca. 2degreesC lower. Unravelling the SST signal into dominant seasonal components suggests maximum winter cooling of 2degreesC at around 6.0 ka, whereas the cooling at ca. 3.0 ka might be the result of a spring temperature cooling of 2-3degreesC. The events, lasting several hundred years, are apparently synchronous with those in the Aegean Sea, where they have been related to known cooling events from the Greenland ice-core record. A distinct interruption in Adriatic Sea sapropel S1 is not clearly accompanied by a local drop in winter temperatures, but seems to be forced by ventilation, which probably occurred earlier in the Aegean Sea and was Subsequently transmitted to the Adriatic Sea.
