  • Microbial Census of Deep-Sea Sediments


  • We proposed applying 454-based tag pyrosequencing to investigate how microbial communities change with sediment depth, age, lithology, and porewater geochemistry in the sediment that underlies one of the highest productivity regions in the world ocean. To accomplish this goal, we analyzed extracted DNA from 16 samples taken in high resolution in conjunction with detailed porewater geochemistry. This dataset provides an unprecedented insight into the microbial ecology of a highly productive open ocean site (25 cm/k.y) to a sediment depth of 404 m and an age of 1.6 Ma.
