Investigation of the Distribution of Carbon Dioxide between the Atmosphere and the Sea
131 pages Measurements of the distribution of CO2 between the atmosphere and the sea are presented with a description of the apparatus used and its calibration. The measurements were made on a series of cruises into the Gulf of Mexico, the Northern Caribbean Sea and the Western North Atlantic Ocean;...

131 pages Measurements of the distribution of CO2 between the atmosphere and the sea are presented with a description of the apparatus used and its calibration.
