Coccolithophore assemblage data from sediment core 162-984C from the subpolar North Atlantic ocean spanning the past 24 ka. The assemblage data were used to assess changes in biodiversity and assemblage composition during the past 24 ka, i.e., from the Last Glacial Maximum (LGM) to the current warm...
