Past environmental changes in the Baltic area are discussed on the basis of pollen and spores recovered from marine sediments in a series of cliff sections at Mommark, in southern Denmark. The sediment succession represents Jessen & Milthers' (1928) Eemian pollen zones c‐h, or Andersen's (1961, 1975) zones E1/2‐E7, as well as the earliest Weichselian pollen zone i, or EW‐1, the Herning Stadial. A correlation with annually laminated German sequences (e.g. Bispingen) indicates that the sequence spans approximately 11000 years. Marine deposition began c. 300 years after the beginning of the Eemian Interglacial Stage and continued to shortly before the end of pollen zone E7, at c. 10 600 years after the beginning of the Eemian. Sedimentation rates varied through the time period represented by the sequence, with initial deposition relatively rapid at c. 0.35 cm yr ‐1 for the first c. 300 years. Rates then decreased to 0.029 cm yr ‐1 for the next 2700 years and remained low, though varying, throughout the rest of the sequence. Overall, the rates indicate that sediment supply was highly restricted throughout the interglacial, possibly reflecting the dense forest vegetation that colonized the hinterland.
