16S sequence data from Puigcorbé et al. Frontiers in Microbiology article - Impact of particle flux on the vertical distribution and diversity of prokaryotic communities in two East Antarctic polynyas

The study compares the prokaryotic community structure, determined by high-throughput Illumina sequencing of the 16S rRNA genes. We examined the variability in the prokaryotic communities associated with free-living (0.2 – 0.8 mm), small (0.8 – 53 mm) and large (>53 mm) particles collected along the water column and compared them to the magnitude of the particle export fluxes estimated using thorium-234 as particle tracer. The sampling was performed on board of the R/V Aurora Australis (AA-V02 2016/17 - AU1602) between December 8, 2016 and January 21, 2017, in the Dalton and the Mertz polynyas (East Antarctica; 67.2 - 66.8°S and 119.5-145.8°E). Data collection procedures are described in the paper "Impact of particle flux on the vertical distribution and diversity of size-fractionated prokaryotic communities in two East Antarctic polynyas" by Viena Puigcorbé et al., Frontiers in Microbiology (doi:10.3389/fmicb.2023.1078469) Here we provide the raw sequence data, together with the non-rarefied OUT table, taxonomy table and environmental data used in this study. The sequences are in the fasta format, they have treated and quality filtered as described in the article.
