Abstract: |
We showed that copepod carcasses were prevalent in the dynamic subtropical convergence zone where the water column stratification pattern can change considerably across the front as warm and cold water masses converge. The proportional numerical abundances of copepod carcasses increased with depth, reaching up to 91% at 300–400 m. On average 14–19% of the copepods in the upper 200 m were carcasses. Combining field and experimental data, we estimated that decomposing copepod carcasses were a negligible oxygen sink in the STCZ, but sinking carcasses represent an overlooked source of the passive carbon sinking flux in the area. |
