| High resolution quantitative analyses have been carried out on coccolithophore assemblages at the Ionian Sea core KC01B in the time interval crossing the deglaciation between Marine Isotope Stages 20 and 19 (Termination IX, in Lower-Middle Pleistocene). Principal Component Analysis emphasizes the temperature as the first environmental parameter affecting coccolithophore assemblages that reach a higher number of coccoliths per gram of sediment during the interglacial. Patterns of key taxa indicate the occurrence of a terminal stadial phase in the late MIS 20 when the presence of cold, turbid and low salinity surface waters in the Ionian Sea are highlighted by prominent peaks of Coccolithus pelagicus ssp. pelagicus, Gephyrocapsa muellerae >3 ƒÝm, and... |
