Fig. 2: CO2 partial pressure (pCO2) and water-air CO2 flux in estuary types and disturbance groups.
From: High carbon dioxide emissions from Australian estuaries driven by geomorphology and climate
Median (red line), mean (red asterisk), 1st and 3rd interquartile ranges (box caps), minimum and maximum values (whiskers) of pCO2 and water-air CO2 flux at per-minute resolution in the (A) lagoons (blue, n = 3789), small deltas (green, n = 3622), and tidal systems (yellow, n = 5720); and (B) low (black, n = 1796), moderate (dark grey, n = 3189), high (grey, n = 3677), and very high (light grey, n = 4469) disturbance groups. Outliers were omitted from the figures. Dotted line along the x-axis represents atmospheric pCO2 and water-air flux CO2 equilibrium. Letters above figures denote statistical differences among estuary types, with letters that are the same indicating no significant difference (PERMANOVA, two-tailed, and at 95% confidence interval).
