Fig. 3: Strong correlations between pCO2, CH4, %N2O and %O2 in the Andean headwater and piedmont streams.

From: Andean headwater and piedmont streams are hot spots of carbon dioxide and methane emissions in the Amazon basin

Fig. 3

Variations of the partial pressure of CO2 (pCO2), CH4 dissolved concentration, N2O saturation level (%N2O), as a function of oxygen saturation level (%O2) (a, c, e), CH4 and%N2O as a function of pCO2 (b, d), and %N2O as a function of dissolved inorganic nitrogen (DIN) (f) in the Napo streams. Symbols show the median and error bars the interquartile range, stations in the main-stem are shown by blue circles and in the tributaries by green squares, and black lines indicate linear or exponential fits to the data. Solid lines show fits to the data (Supplementary Table 4).
