Abstract:
This dataset provides the pollen and spore counts for the MIS-5a sediment sequence retrieved from Sokli (Finland) in 2010. Counts per taxon are presented against depth (m). Non-pollen palynomorphs (NPPs) and conifer stomata were also counted from the pollen slides and these data are presented alongside the pollen counts. The number of Eucalyptus markers encountered during analysis are also presented ("Added marker"). The pollen dataset provides information on terrestrial and aquatic/telmatic vegetation dynamics (Helmens et al., 2021). A total of 40 samples was analysed, with samples prepared using HCl, KOH, sieving (212 μm mesh), Na-pyrophosphate, acetolysis, and bromoform heavy-liquid treatments and counted using a light microscope (400× magnification). The samples were prepared in the laboratories of University of Amsterdam, The Netherlands, and counted in the laboratories of University of Helsinki, Finland.
