Due to high terrestrial runoff, the Baltic Sea isrich in dissolved organic carbon (DOC), the light-absorbing fraction of which is referred to as coloreddissolved organic matter (CDOM). Inputs of DOC andCDOM are predicted to increase with climate change,affecting coastal ecosystems. We found that therelationships between DOC, CDOM, salinity, and Secchidepth all differed between the two coastal areas studied; theW Gulf of Bothnia with high terrestrial input and the NWBaltic Proper with relatively little terrestrial input. TheCDOM:DOC ratio was higher in the Gulf of Bothnia,where CDOM had a greater influence on the Secchi depth,which is used as an indicator of eutrophication and henceimportant for Baltic Sea management. Based on the resultsof this study, we recommend regular CDOM measurements in monitoring programmes, to increase the value ofconcurrent Secchi depth measurements.
