Short summary
The study characterizes the microbial community composition of a cold-water coral mound. Roche GS-FLX amplicon sequencing was carried out targeting Bacteria and Archaea. Water is well-mixed at 400m depth, less so at 5 mab, where composition of communities differed among summit, slope and off-mound. Near-bottom water differed from 5 mab, showing that waters in between frameworks represent a separate microbial habitat. Patterns of microbial distribution are coupled to topo- and hydrography.
