Sample preparation techniques applied include smear-slides, a modified settling method for the LM, a modified settling method for the SEM, and a filtration technique for the SEM. All samples were prepared from the same site (ODP Site 643, Norwegian Sea). In addition, the reproducibility of the individual counts, and the homogeneity of the individual methods, were tested and the data of the individual counts have been checked with each other.completedPaleobotanyalgaeArctic Oceancalcareous compositionCoccolithophoraceaedepositionfiltrationLeg 104microfossilsmicroscope methodsnannofossilsNorwegian SeaOcean Drilling ProgramODP Site 643paleo-oceanographypaleoecologyPlantaequantitative analysissample preparationSEM datasmear-slide methodurn:org.iodp:exp:104urnlargerWorkCitationcampaignurn:org.iodp:exp:104:site:643urnlargerWorkCitationstudyurn:org.iodp:exp:104urnlargerWorkCitationcampaignEnglishgeoscientificInformation-25.000015.000062.000080.0000Norwegian Sea
