Abstract:

This dataset provides absolute counts of botanical and zoological macro-remains obtained from the MIS-5a sediment sequence retrieved from Sokli (Finland) in 2010. Counts per taxon are presented against sediment depth (m). The macroremain dataset consists of a total of 29 samples and provides information on terrestrial and aquatic ecosystem dynamics (Helmens et al., 2021). Macrofossil samples were prepared from subsamples of mainly ca. 10 ml³. The sediment was sieved using a 100 μm mesh under running water and the residue examined using stereo- and high-magnification light microscopes. The analyses were performed in the laboratories of the University of Helsinki, Finland.
