Metabolic stoichiometry predicts that dissolved oxygen (O₂) and carbon dioxide (CO₂) in aquatic ecosystems should covary inversely; however, field observations often diverge from theoretical expectations. Here, we propose a suite of metrics describing this O₂ and CO₂ decoupling and introduce a conceptual framework for interpreting these metrics within aquatic ecosystems. Within this framework, we interpret cross‐system patterns of high‐frequency O₂ and CO₂ measurements in 11 northern lakes and extract emergent insights into the metabolic behavior and the simultaneous roles of chemical and physical forcing in shaping ecosystem processes. This approach leverages the power of high‐frequency paired O₂–CO₂ measurements, and yields a novel, integrative aquatic system typology which can also be applicable more broadly to streams and rivers, wetlands and marine systems.

配对的O2–CO2测量值可提供有关水生生态系统功能的最新见解

代谢化学计量法预测，水生生态系统中的溶解氧（O ₂）和二氧化碳（CO ₂）应该相反地转化。但是，实地观察常常与理论期望背道而驰。在这里，我们提出了一套描述这种O ₂和CO ₂去耦的指标，并介绍了用于解释水生生态系统中这些指标的概念框架。在此框架内，我们解释了高频O ₂和CO _2的跨系统模式在北部11个湖泊中进行测量，并从中得出有关代谢行为以及化学和物理强迫在塑造生态系统过程中同时发挥作用的最新见解。这种方法利用了高频配对O ₂ -CO ₂测量的强大功能，并产生了一种新颖的，综合的水生系统类型学，它也可以更广泛地应用于河流，河流，湿地和海洋系统。
