Relative differences between the Freshwater at Ambient Concentrations and Baseline experiments for DO and TA. Relative difference (%) of DO (top row) and TA (bottom row) between the Freshwater at Ambient Concentrations and Baseline simulations at four stations in the first year of the simulation. Positive (negative) values indicate that the former experiment showed higher (lower) values than the baseline. Blue and gray lines indicate the time series at the surface and bottom layers of the model, respectively. The dashed line highlights the 0% change. The relative difference in TA is larger than that of DO in the surface layer, indicating a more important role of freshwater loading for the former variable.
