Cross-correlation coefficients for the selected parameters: pH, alkalinity (<i>Alk</i>) in mmol l^-1, salinity (<i>S</i>) in ppt, temperature (<i>T</i>) in °C, <i>p</i>CO₂ in μatm, CO₂ flux (Flux) in mg CO₂ m^-2 d^-1, water volume (<i>V</i>) in m³, gas exchange velocity (<i>k</i>’₆₀₀) in m d^-1 and chemical enhancement factor (<i>α</i>).

For each combination of parameters, the three numbers are the cross-correlation coefficients observed for King Talal (upper), Wadi Al-Arab (middle) and Al-Wihdeh (lowest) dams. The most significant correlation coefficients (p<0.05) are marked bold, while p<0.1 for the remaining correlations. Not significant correlations are marked as x.
