Understanding the dynamics of p CO2 and p CH4 is important for evaluating carbon emissions from the aquatic environment. While temporal dynamics of p CO2 and p CH4 have been extensively studied, there is a noticeable gap in the literature concerning their spatial characteristics. In this study, we used boat-mounted sensors to directly measure p CO2 and p CH4 with high spatial resolution across seasons in Xuanwu Lake (XWL), an urban lake in Nanjing, China. Additionally, water chemistries were measured at selected sites for correlation analysis. Sensitivity analysis was performed to assess the effects of measurement location and density on carbon flux estimates.
