| contents | This dataset provides the pollen counts for the Early Weichselian sediment sequence retrieved from Sokli (Finland) in 2002. Counts per pollen taxon are presented against sediment depth (m). Non-pollen palynomorphs (NPPs) were also counted from the pollen slides and these data are presented alongside the pollen counts. The number of Lycopodium spores encountered during analysis are also presented ("exotic"). The pollen dataset provides information on terrestrial and aquatic/telmatic vegetation dynamics (Helmens et al., 2012). A total of 63 samples was analysed, with samples prepared following Fægri & Iversen (1989) with additional sodium polytungstate heavy-liquid separation to remove clastic material. The material was sieved over a 7-8 mm nylon mesh to remove fine particles, mounted in glycerine jelly and sealed with paraffin wax. Fossils were counted using a light microscope (400× magnification). The samples were prepared in the laboratories of VU University Amsterdam, The Netherlands, and counted in the laboratories of Stockholm University, Sweden. |
