Here, we explore the potential for the Phillips sampler to provide a representative sample of the diatom assemblage of a whole storm run-off event. We addressed this by comparing the diatom community composition of the Phillips sampler to the composite community collected by the automatic samplers. As a control, we also checked if the particle size distribution of the suspended sediment collected by the Phillips sampler was similar to the composite distribution collected by the automatic sampler. We consider automatic samplers as sampling fully representative samples of a storm run-off event. The dataset contains relative diatom abundances (%) after applying the cut-off criteria of 1% and results of indicator variables and diatom indices per sample. Diatom biovolume and ecological guilds per taxa are also provided. Furthermore, measurements of discharge, turbidity, suspended sediment concentration (SSC) and particle size distribution (PSD) are given. The results of PSD are given as provided by the software. For more information we refer to the manual of the LISST 200X.
