Note
This datatable is part of the Gull Lake long-term Microcystis monitoring dataset.
This dataset consists of 13 years of observations of Microcystis biomass and microcystin in an oligotrophic lake (Gull Lake, MI, USA), where it is promoted by invasive zebra mussels (Dreissena polymorpha). Annual means are reported for all variables. As originally published, the data were used to assess the influence of interannual variation in water temperature and zebra mussel mortality on Microcystis dynamics in an oligotrophic lake
