Upper circumpolar deep water influences microbial functional gene composition and diversity along the southern Central Indian Ridge and eastern Southwest Indian Ridge.

ABSTRACT: Deep sea microbial communities play a significant role in global biogeochemical processes. However, the depth-wise metabolic potential of microbial communities in hydrothermally influenced Central Indian Ridge (CIR) and Southwest Indian Ridge (SWIR) remains elusive. In this study, a comprehensive functional microarray-based approach was used to understand factors influencing the metabolic potential of microbial communities and depth-driven differences in microbial functional gene composition in CIR and SWIR. Stratified water column sampling at surface, mid, turbid/plume layer, and near bottom was done along with pertinent environmental variables at various locations along the ridges. The majority of genes (~38%-41%) throughout the water column in both regions encoded for C-cycling, particu
