Time series of plankton data from Lake Mjøsa, Norway

Summary

This paper gives an overview of the >40 years long time series of zooplankton, phytoplankton and other environmental monitoring data from Lake Mjøsa in South-East Norway. The lake was impacted by eutrophication in the 70s-80s and has been successfully restored to good ecological status. The dataset currently comprises zooplankton and phytoplankon at species level from early 1970s to 2015, and water chemistry data from the same period. The phytoplankton and water chemistry data are available online from NIVA's web portal AquaMonitor and will be updated regularly with new monitoring data. Zooplankton data are not yet publicly available, but publication through AquaMonitor is foreseen for future projects.
