The distributions of chlorin components as well as chlorophylls c and β-carotene in postglacial sediments (down to ca 5 m depth), collected from the Gotland Deep in July 1997, have been determined. The major pigments were similar to those identified in recent (0–10 cm) sediment extracts of the Gdansk Deep. High amounts of well preserved chlorins, including intact chlorophyll a, provide evidence for high primary production in the past, anoxic sedimentation and favourable postdepositional conditions. In addition, the results reveal several extremely rapid changes in the Baltic environment over the last 8000 years caused by different physico-chemical conditions and subsequent changes in phytoplankton occurrence, biomass and algal species.
