Fig. 2: RF, γDIC, β, and γCO2 vary with pH and pCO2.
From: A new indicator can assess absorption capacity for carbon dioxide and ocean acidification
The simulation conditions are at salinity = 34.8 and temperature = 18.3 °C. a, b, c The white solid line is Alk = 2250 μmol·kg−1. d The variation of the four factors with pH at Alk = 2250 μmol·kg−1. Neither the RF nor γDIC is suitable for assessing seawater absorption capacity for CO2 at pH < 7.5 (This critical threshold will vary in different Alk, temperatures, and salinity).
