Partial pressure (or fugacity) of carbon dioxide, sea surface temperature, and salinity from surface underway survey in global oceans from October 22, 1957 to March 21, 2013 (Version 2012) (NODC Accession 0059946)

Metadata Updated: March 10, 2021

Approximately 6.7 million measurements of surface water pCO2 made over the global oceans during 1957-2012 have been processed to make a uniform data file. 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. 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 micro-atm on the average. The names and institutional affiliations of the contributors are listed in Table 1. A column is added for reporting the partial pressure of CO2 in seawater in units of Pascals. The documentations for the previous versions (V1.0, V2007, V2008, V2009, V2010 and V2011) of our database are available at CDIAC http://cdiac.ornl.gov/ftp/oceans/LDEO_Database/

The global pCO2 data set is available free of charge as a numeric data package (NDP) from the Carbon Dioxide Information Analysis Center (CDIAC). The NDP consists of the oceanographic data files and this printed documentation, which describes the procedures and methods used to obtain the data.

VERSION 2012: This version is referred to as Version 2012, and includes the data collected through 31 December 2012. In this update, about 277,000 pCO2 measurements made during 29 new cruise/ship files are added to the previous version 2011. The new additions include the new data from our field operations aboard L.M. Gould, N.B. Palmer, Marcus G. Langseth, US Coast Guard Cutter Healy. These data files from Gould, Palmer, Langseth, and Healy are also posted on our LDEO website: http://www.ldeo.columbia.edu/res/pi/CO2/. In addition, several files from the Volunteer Observation Ships (VOS) program, M/V Explorer of the Seas, and 3 NOAA ships., which have recently been released for years 2010 - 2012, are combined into the master file of CDIAC http://cdiac.ornl.gov/oceans/.
