Figure 7. Bacterial activities near the BSR at Site 995. Sulfate reduction (solid triangles), methane oxidation (open circles), methanogenesis from H₂:CO₂ (solid squares), methanogenesis from acetate (open squares), acetate oxidation to CO₂ (solid circles), and bacterial growth rates indexed with thymidine incorporation (open triangles) are shown. The shaded area at 440 mbsf and above indicates the zone where the presence of hydrate was inferred.
