Fig. 5: Relationships between estuary tidal range40 and water–air CH4 flux in all study estuaries and in estuary types.
From: Low methane emissions from Australian estuaries influenced by geomorphology and disturbance
The linear fit lines indicate significant correlations (see Supplementary Notes). Data resolution is one sample per every 5 salinity change or 8 km travelled (discrete sampling intervals) across a all estuaries (n = 47), and in b lagoons (n = 21), c small deltas (n = 12), and d tidal systems (n = 14). Note the different scales on the x-axis. Plot data can be found in Supplementary Data 1.
