| Abstract: | The total inorganic carbon dioxide-oxygen relationship in the ocean has been studied previously using two different approaches, one of which is theoretical and the other is statistical. Discrepancies between the two sets of results have been solved in this work by applying multiple linear regression analysis to express total inorganic carbon dioxide, normalized to constant S‰, as a function of potential temperature and total alkalinity and oxygen normalized to constant S ‰. Results of the regression are in agreement with the assumption that total alkalinity changes in the open ocean are only due to S ‰ changes and calcium carbonate dissolution or precipitation; and with Redfield's model for the prediction of the total inorganic carbon dioxide-oxygen ratio for the biochemical oxidation. |
