Flow Cytometry data gathered in a biomonitoring project in the Warnow Estuary and the Baltic Sea coast with high spatio-temporal resolution (OTC-Genomics)

Estuaries and coasts are characterized by ecological dynamics that bridge the boundary between habitats, such as fresh and marine water bodies or the open sea and the land. Because of this, these ecosystems harbor ecosystem functions that shaped human history. At the same time, they display distinct dynamics on large and small temporal and spatial scales, impeding their study. Within the framework of the OTC-Genomics project, we compiled a data set describing the community composition as well as abiotic state of an estuary and the coastal region close to it with unprecedented spatio-temporal resolution. We sampled fifteen locations in a weekly to twice weekly rhythm for a year across the Warnow river estuary and the Baltic Sea coast. From those samples, we used Flow Cytometry to capture autotrophic (and autofluorescent) and heterotrophic (dyed using SYBR Green) cell counts and community compositions.
