We would like to let you know that the new version of the Global Ocean Surface Water Partial Pressure of CO2 Database (LDEO Database Version 2019) has been published at the Ocean Carbon Data System (OCADS) of NOAA National Centers for Environmental Information (NCEI). Approximately 14.2 million measurements of surface water pCO2 made over the global oceans during 1957-2019 have been processed to make a uniform data file in this Version 2019. 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. 567,632 data points consisting of 158 leg/cruise segments were added in this version.
