| Summary: | Quantifying effects of Ocean Acidification (OA) on marine primary and secondary producers is of acute interest, as they could translate up to higher trophic levels and ultimately may alter ecosystem services including fishery yields. A mesocosm approach was used to investigate the effects of OA on a natural plankton community in coastal waters off Norway by manipulating CO2 partial pressure (pCO2). Eight enclosures were deployed in the Raunefjord near Bergen. Treatment levels were ambient and elevated pCO2 of ~ 2000 µatm each in four replicate enclosures. The experiment lasted for 53 days in early summer of 2015. To assess impacts of OA on the plankton community, we measured phytoplankton and protozooplankton biomass and total seston fatty acid (FA) content. In both the control and the elevated pCO2 treatment, the plankton community was dominated by the dinoflagellate Ceratium longipes. In the elevated pCO2 treatment, however, this species as well as other dinoflagellates were strongly negatively impacted: ... : Supplement to: Dörner, Isabel; Hauss, Helena; Aberle, Nicole; Lohbeck, Kai T; Spisla, Carsten; Riebesell, Ulf; Ismar, Stefanie M (2020): Ocean acidification impacts on biomass and fatty acid composition of a post-bloom marine plankton community.
