Marine sediments are vast, underexplored habitats and represent one of the largest carbon deposits on our planet. Microbial communities drive nutrient cycling in these sediments, but full extent their taxonomic metabolic diversity remains to be explored. Here, we analysed shallow coastal deep subseafloor sediment cores from 0.01 nearly 600 metres below seafloor, Western Pacific Region. Applying metagenomics, identified several clusters across all samples, which mainly aligned with depth type. Inferring functional patterns provided insights into possible ecological roles main microbial taxa. These included Chloroflexota , most abundant phylum whereby classes Dehalococcoida Anaerolineae dominated deep-subsurface respectively. Thermoproteota Asgardarchaeota were phyla among Archaea, contributing high relative abundances Archaea reaching over 50% some samples. We recovered high-quality metagenome-assembled genomes for prokaryotic lineages proposed names three phyla, i.e. Tangaroaeota phyl. nov. (former RBG-13-66-14), Ryujiniota UBA6262) Spongiamicota UBA8248). Metabolic capabilities samples ranged aerobic respiration photosynthesis shallowest layers heterotrophic utilization, sulphate reduction methanogenesis deeper anoxic sediments. also taxa potential involved nitrogen sulphur utilization. In summary, this study contributes understanding benthic marine
