Papposphaera iugifera nov. sp. from West Greenland, Svalbard, and the Baltic Sea
We are currently revisiting coccolithophore genera and species described from high latitudes in both hemispheres, and also in the process describing new taxa when appropriate, with the aim of providing the best possible framework for polar species segregation based on external morphological features...
