Measurements of the equilibrium concentration of carbon dioxide with respect to air in the surface waters of the Kara, Barents, and Norwegian Seas during the late summer of 1967 show undersaturation. The North Atlantic Ocean during late summer is slightly undersaturated except for limited areas such as the North Sea, south of Nova Scotia, and within the Gulf Stream, where supersaturation is found. Observations across the North Atlantic Ocean from the North Sea to Massachusetts Bay agree closely with the results of K. Buch from a similar track in 1935. The data indicate that for a 1C increase in surface sea temperature there is a 10 ppm increase in CO 2 concentration. An increase in oxygen concentration of 1.0 ml/liter is associated with a decrease of 45 ppm CO 2 . In the Barents Sea, a linear relationship is found between CO 2 and salinity, with a rise of 39 ppm CO 2 per part per thousand increase in surface salinity.
