Carbon biomass (μgC L−1) of mixotrophic (MT) and heterotrophic (HT) dinoflagellates during the time of a 2.5-year weekly monitoring programme at Helgoland Roads in comparison with chlorophyll a concentration (μg L−1) measured on a work-daily basis via in situ fluorescence as a regular parameter of the long-term series
