Short summary
Physicochemical determinants of microbiome architecture across continental shelves–slopes are unknown, so we explored the geomicrobiology along 3 m sediment horizons of seasonal (shallow coastal) and perennial (deep sea) hypoxic zones of the Arabian Sea. Nature, concentration, and fate of the organic matter delivered to the sea floor were found to shape the microbiome across the western Indian margin, under direct–indirect influence of sedimentation rate and water column O2 level.
