This monograph, volume 12 in the series Diatom Monographs, presents results of diatom analyses of seven sediment cores taken from various depths of the Gulf of Gdansk between the Hel Peninsula and the coast of Gdansk and Gdynia. A further eight cores were drilled in the northern, southern and central part of the Vistula Lagoon. The present investigation enabled the determination of: the differentiation of diatom assemblage zones based on floristic spectra and ecological groupings; the correlation of palaeoecological units with reference to the following stages: Mastogloia Sea, Littorina Sea, Post - Littorina Sea including the last environmental changes linked to anthropogenic factor; the description of defined diatom biofacies, based on statistical analyses; the reconstruction of spatial and temporal development of both basins, with the emphasis on the role of inflows of sea and riverine waters.weiterlesen
