Cross-section through the Romanche Fracture Zone (down to 4500 m depth) showing the horizontal and vertical variation of the prokaryotic dissolved inorganic carbon (DIC) fixation rates (μmol C m−3 days−1). Dots indicate positions where the respective parameter was measured.
fem12073-sup-0002-FigS2.pdfapplication/PDF120KFig. S2. Depth profiles of mean abundances of archaeal amoA genes obtained with two different primer sets (Table 2), 16S rRNA gene abundance of marine Thaumarchaeota and accA-like genes determined by Q-PCR. Dashed lines delineate the water mass sampled, see Table 1.
