- Abstract
The feasibility of estimating the partial pressure of CO{sub}2{end} (PCO{sub}2{end}) from underway measurements of sea-surface temperature, pH, salinity and specific alkalinity was tested in the Gulf of California; PCO{sub}2{end} was also estimated from satellite-obtained sea-surface temperature (SST) by applying the pH-temperature relationship of the underway data to the imagery. The pH and PCO{sub}2{end} values were correlated with the major thermal features of the area studied. At the southern, warmer end of the gulf, estimated PCO{sub}2{end}values are approximately 30 to 40 mu atm above an expected surface equilibrium value of ca. 356 mu atm. Maximum PCO{sub}2{end} values of about 550 mu atm were found in the region of the midriff islands. Forthe 700-km transect, positive correlations were found between pH, insitu measured temperature (IST) and SST. For the warm zone, there was also a negative correlation between satellite-derived pigment (logP) and pH and temperature. LogP did not correlate with the other variables in the cold zone. The feasibility of using "ships of opportunity" to monitor pH and surface temperature as part of a world-wide PCO{sub}2{end} monitoring program is discussed.
