a OCAR data of 115 Chinese lakes and (b) their positive relation to POC concentrations. c Mean CO2 concentrations of 149 lakes and (d) their positive correlation with DOC/POC ratios. Error bars indicate Standard deviation. OCAR: OC accumulation rate. Pop. in 2015: 1 km grid-based population density (person km−2). Source data are provided as a Source Data file.
