Abstract

 The awareness of coastal blue carbon is increasing, and the dynamics of the CO₂ fugacity (fCO₂) in shallow coastal waters are becoming critical for evaluation of CO₂ fluxes. We carried out numerical computations using a three-dimensional environmental flow model including snowmelt-related groundwater discharge and estimated fCO₂ in water from salinity, biological metabolism, and calcification. Under the influence of the low salinity from the growndwater, fCO₂ in water was found to increase slightly as a result of the opposite effect of a decrease in fCO₂ with decreasing DIC and an increase in fCO₂ with decreasing TA.
