Deep sediments (to 660 cm) from the Baltic Sea, collected in 1996-1997, were analysed for content of chlorophyll a and its immediate derivatives (chlorins: phaeophytin, pyrophaeophytin, phaeophorbides and steryl chlorin esters) using the diode-array HPLC method. These compounds were generally well preserved. The concentrations of both particular and total chlorins varied greatly depending on the sediment layer and were surprisingly high in some cases, comparable to concentrations in contemporary Baltic sediments (0-1cm layer).
