Profiles from 0 to 700 m of temperature (a), chlorophyll a (b), dissolved oxygen (c), NO3 (d) and NO2 (e) in the Carmen Basin, and amoA gene copies from the Carmen (f) and Guaymas Basins (g). Data from 0 to 100 m are from the group A archaeal amoA assay and 300–650 m from the general assay. Error bars denote one standard error of the triplicate quantitative PCR (qPCR) measurement and are not visible when less than the width of the data point.
