[Author's Abstract] Areas of low oxygen in the world’s oceans provide a suitable habitat for bacteria involved in the nitrogen removal process. The expansion of one such area in the Eastern Tropical North Pacific (ETNP) provides a larger zone for this process to occur. Results from isotopic labeling experiments suggest that the two major pathways of nitrogen loss, denitrification and anammox, are both present in the ETNP but vary in location and intensity due to responses to biological, chemical, and physical factors. |
