  4. 3. Holocene environmental changes recorded by diatom stratigraphy in the southern Baltic Sea

    Författare :Elinor Andrén; Rick W. Batterbee; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; allmän och historisk geologi; General and Historical Geology;

    Sammanfattning : Sediment cores from the southern Baltic Sea and the Oder River estuary are analysed for their siliceous microfossil assemblages and organic carbon content. Long piston cores from the Bornholm and Gotland Basins provide data on the long-term Holocene history of the Baltic proper and serve as a natural background when evaluating the most recent environmental changes recorded in the short gravity cores.
