The monitoring of phytoplankton covers pigments, abundance and biomass data and concerns the water column habitats.
The sub-programme covers pigments and supports the eutrophication related HELCOM core indicator for Chlorophyll-a.
The dataset on abundance and biomass of phytoplankton
is extensive and the sub-programme can be used as an approximation for total
There are no HELCOM core indicators linked to the sub-programme at this time. The pre-core indicator 'Diatom/Dinoflagellate index (Dia/Dino index)' is being tested.
