This dataset comprises the microbial community composition associated with the outer bell of the deep pelagic jellyfish Periphylla periphylla exposed to anthropogenic disturbance. Specifically, we tested the effects of ocean warming and sediment plumes from deep-sea mining during ex situ experiments, using Periphylla collected in the Lurefjord and Sognefjord, Norway, in 2021. Microbial community composition is given in raw counts for each amplicon sequence variant (ASV) encountered, based on 16S rRNA sequencing. Taxonomy for each ASV is listed, including Kingdom, Phylum, Class, Order, Family, Genus and Species, which were assigned using QIIME2 and the Silva 132 99% OTUs 16S rRNA database (Quast et al. 2013).
