Quaternary Arctic planktonic foraminifera: morphological differentiation and taxonomic reassessment of subpolar spinose taxa

Abstract. Planktonic foraminifera in the modern Arctic Ocean are dominated by the non-spinose polar species Neogloboquadrina pachyderma. Acmes of two spinose, presumed subpolar taxa in Quaternary central Arctic sediment cores are therefore anomalous, implying significantly differ...
