Global Ocean Surface Water Partial Pressure of CO2 Database: Measurements Performed During 1957-2017 (LDEO Database Version 2017) (NCEI Accession 0160492)

browse graphicPreview graphic
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. We have added about 2.1 million data points comprised of 511 leg/cruise segments in this version. A total of 246,032 of these were collected on the 5 ships in our current field program. These 5 ships operate primarily in high latitudes in both hemispheres and have built decades long records in these areas. R/V Nathaniel B. Palmer’s system has been operating since 1995, R/V Laurence M. Gould’s system since 2001, USCGC Healy since 2011, R/V M. Langseth since 2010, and R/V Sikuliaq since 2015. Our contribution to this database through many years of 2.96 million records primarily for the polar and sub-polar seas. These underway data have been quality controlled and corrected for the time lag and temperature differences between the water intake and pCO2 measurements. The remainder of the 2.1 million new data were added from various web sites for Ships of Opportunity (SOOP) funded by different agencies primarily NOAA's ocean observations and monitoring division. In order to allow re-examination of the data in the future, a number of measured parameters relevant to pCO2 in seawater are listed. The overall uncertainty for the pCO2 values listed is estimated to be ± 2.5 uatm on the average.
