Expression of selected functional genes across the whole dataset related to (A) carbon fixation, (B) nitrogen metabolisms, (C) methanogenesis, (D) sulfur oxidation, (E) other sulfur metabolisms, (F) iron, and (G) hydrogen. Of these genes, only ammonia monooxygenase showed statistically significant differences in expression between sampling methods (higher expression in Niskin samples). Genes shown in blue showed statistically significantly more expression in Sites 1–4, while those in yellow were statistically significantly more expressed in Site 4 samples.
