Short summary
Microbes are the main drivers of productivity and nutrient cycling in the ocean. We present a combined approach assessing C and N uptake and microbial community diversity across ecological provinces in the Southern Ocean and southern Indian Ocean. Provinces showed distinct genetic fingerprints, but microbial activity varied gradually across regions, correlating with nutrient concentrations. Our study advances the biogeographic understanding of microbial diversity across C and N uptake regimes.
Microbes are the main drivers of productivity and nutrient cycling in the ocean. We present a...
