Short summary
Coccolithophore distribution in 88 surface sediment samples in the Atlantic Ocean and western Mediterranean was mainly influenced by salinity at 10m depth. A quantitative coccolithophore-based transfer function was developed and applied to a fossil sediment core to estimate sea surface salinity (SSS). The quality of this function and the reliability of the SSS reconstruction were assessed by statistical analyses and discussed. Several centennial SSS changes are identified for the last 15.5 ka.
