The concentration of palynomorphs was estimated from the marker-grain methods and reported in specimens per cubic centimetre of wet sediment. The palynomorphs include marine microfossils (dinocysts, organic linings of foraminifers and remains of ciliates), freshwater microfossils (Pediastrum), pollen and spores from land vegetation, in addition to reworked palynomorphs.The data are reported vs depth and vs ages calibrated based on Marine20.
