We would like to let you know that the new LDEOv2017 Database was published at OCADS NCEI: https://www.nodc.noaa.gov/ocads/oceans/LDEO_Underway_Database/. Approximately 13.0 million measurements of surface water pCO2 made over the global oceans during 1957-2017 have been processed to make a uniform data file in this Version 2017. 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.
