Abstract
Actively venting high temperature deep-sea hydrothermal vent deposits along tectonic spreading centers and in backarc basins harbor a rich diversity of thermophilic Bacteria and Archaea, many of which have no representatives in cultivation nor any genomic representation in databases. Here, in order to produce a global-scale time series metagenomic resource for studying the microbial functional and genomic diversity in these high temperature ecosystems, we obtained 70 metagenomes from collections across spatial and temporal gradients from 21 different vent fields spanning 16 years (1993-2009). The dataset (Deep-Sea Hydrothermal Vent dataset (DSV70)) includes 3.56 Tbp of raw DNA sequence reads, that have been assembled to produce 7,422 medium- to high-quality (based on CheckM2) metagenome-assembled genomes (MAGs) of Bacteria (6,063 MAGs) and Archaea (1,359 MAGs). Collectively, this DSV70 dataset and the published 40 metagenomes from more recent deep-sea collections (2004 to 2018), represent a valuable resource for exploring the functional and phylogenomic diversity of the deep-sea hydrothermal microbiomes, and provide many reference genomes for studies in the taxonomy and systematics of poorly studied microbial lineages. Further, with the interest in mining the mineral resources at deep-sea vents, the DSV70 provides a genomic legacy for monitoring impacts on the microbial communities in these systems.
