The calcareous nannofossil assemblages from sediment core GeoB2908-7 from the equatorial Atlantic were examined to document oceanographic changes in surface waters during the last 365 ka. Coccolith counts were made manually on filtered samples using a Zeiss DSM 940A scanning electron microscope at 3,000x or 5,000x magnification. The surface water circulation of the equatorial Atlantic has changed drastically, as can be seen from changes in the coccolithophore species composition and absolute coccolith abundances. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.993418"!
