SOCAT: Surface Ocean CO2 Atlas
SOCAT (Surface Ocean CO2 Atlas) represents an effort to "provide a comprehensive, publicly available, regularly updated, global data set of marine surface CO2, which had been subject to quality control (QC)." The data sets are comprised of observations (ship track) and gridded data.
