Dynamics of an Estuarine and Brackish Coastal Biotic Community Captured in High Spatio-Temporal Resolution using 16S Amplicon Sequencing

Here, we report a dataset capturing the diversity and dynamics of the bacterial community at a 16 km stretch of the the Baltic Sea coast and the Warnow river estuary. From April 2022 to May 2023, we took surface water samples at fourteen sampling sites twice weekly and weekly samples at one additional site. After collecting the biomass in the sample on a 47 mm Durapore PVDF filter with a pore size of 0.22 µm, 16S rRNA gene amplicons were sequenced using the primers 5'-CCTACGGGNGGCWGCAG-3' and 5'-GACTACHVGGGTATCTAAKCC-3' (Herlemann et al., 2011) targeting the V3-V4 hypervariable region.
