Abstract

The pressure coefficients of the apparent dissociation constants of carbonic and boric acids in seawater were determined for pressures up to 1,000 atm at 2, 11.6, and 22C in seawater of 34.8‰ salinity and at 13.5C in seawater of 38.5‰ salinity. The results were used to calculate the effect of pressure on the pH and the distributions of the various inorganic carbon species in a deep station in the North Pacific Ocean.
