Short summary
In the tropical Northwest Pacific, a region of warm and nutrient‑poor ocean water, we investigated why oxygen consumption does not match the expected release of nutrients like nitrogen and phosphorus. We sampled from the surface to 2000 m and found that layering limits mixing, traps nutrients at depth, and leaves surface waters nutrient poor. Under these conditions, algae and bacteria recycle materials in ways that decouple carbon breakdown from nitrogen and phosphorus release.
