报告摘要：

Ocean interior O2 responds to changes in solubility, ventilation, and the strength of the biological pump. While climate-driven solubility changes have received considerable attention, the influence of climate on ventilation and net primary production may yield a complex response that is difficult to predict, particularly over a period of centuries. The recovery of O2 in the tropical intermediate waters after 2100 that we describe highlights a possible unanticipated long-term implication of a coupling of Southern Ocean and tropical ocean net primary production and has important implication for biological feedbacks to climate warming. Specifically, denitrification levels in tropical intermediate waters decline below pre-industrial levels, suggesting that the contracting OMZs may offset anthropogenic N2O emissions originating from agriculture and other land sources.
