Biovolumes and Size-Classes of Phytoplankton in the Baltic Sea

Abstract

This report on biovolumes and size-classes of phytoplankton in the Baltic Sea has been produced by the HELCOM Phytoplankton Expert Group (PEG). Most laboratories involved in the HELCOM Baltic Monitoring Programme (COMBINE) have contributed to the work, using regional phytoplankton data. Distinct size- classes and biovolumes were agreed upon and established for most Baltic species which are possible to identify using a light microscope and the Utermöhl counting technique.
