Description: The Lower Saxony Water Management, Coastal and Nature Protection Agency regularly monitors the abundance, biomass, cell size and species composition of phytoplankton species in the East Frisian Wadden Sea. A total of 5 stations are sampled from a monthly to weekly frequency, either throughout the whole year or from March to October. Samples are taken at the surface using a bucket, and kept in 5L canisters to be stored in the cold and dark until subsequent fixation with Lugol's iodine solution and later microscopic analysis. An inverted microscope was used to identify and analyze phytoplankton samples following Utermöhl (1958). The unaccepted or original names of species are given in the 'Species UID' variable, and the accepted identifications are given in the 'Species' variable. The data provides a detailed time series of phytoplankton abundance, biomass, cell size and species composition from 2020 to 2025 in the East Frisian Wadden Sea surface waters.
