We would like to inform you that the LDEO Database Version 2018 (LDEO_Database_V2018) was published at the Ocean Carbon Data System (OCADS) - a data management project within the US NOAA National Centers for Environmental Information (NCEI). Approximately 13.5 million measurements of surface water pCO2 made over the global oceans during 1957-2018 have been processed to make a uniform data file in this Version 2018. Measurements made in open oceans as well as in coastal waters are included. The data assembled include only those measured using equilibrator-CO2 analyzer systems, and have been quality-controlled based upon the stability of the system performance, the reliability of calibrations for CO2 analysis and the internal consistency of data.
The dataset is available from this link: https://www.nodc.noaa.gov/ocads/oceans/LDEO_Underway_Database/.
