Fig. 3: Total alkalinity (TA) as a function of dissolved inorganic carbon (DIC) in Galveston Bay from June 2017 to September 2018.
From: Tropical cyclone-induced coastal acidification in Galveston Bay, Texas
For all plots, symbols are categorized according to sampling month (shape) and year (fill). Shapes: squares for March, circles for June, stars or asterisk for September, triangles for November; filled symbols for 2017 and open symbols for 2018. Diamonds indicate the average calculated endmember values connected by dark gray mixing lines. The standard deviation for each average endmember (error bars on endmembers in (a)) was used to determine the uncertainty associated with the mixing envelope shown by the gray shaded region. The mixing envelope uncertainty includes seasonal variability in the endmember values. The dotted line in (a) indicates a comparative 1:1 relationship for TA:DIC and endmembers are highlighted in yellow for clarity in (a). Color bars show values for b salinity (S), c aragonite saturation state (Ωar), d pH, and e partial pressure of carbon dioxide (pCO2).
