Two thousand and seven hundred-year records of variability of the coccolithophore nannoflora. Top—red: coccolith mass of E. huxleyi, G. ericsonii, and G. muellerae. Bottom—blue: relative abundance of G. oceanica. Colored lines represent the LOESS function and the dotted lines represent polynomial of fourth order to depict the long-term tendencies. Vertical colored bars are synchronous events common to the two series
