(a) The relationship between the O2 departure from atmospheric equilibrium (ΔO2) and excess CO2 (ΔCO2) in surface water in the UYR (LYX to LJXX) during the FP and TP is illustrated. Arrows indicate the potential role of the different drivers60. (b) Box plots depict the offset (distance to the 1:‒1 line, with values above the 1:‒1 line labelled as positive and those below as negative) during the FP and TP. The significance level of correlations is indicated with **p < 0.01. (c) The relationship between the offset and log-transformed CCH4 is presented.
