***************************************************************** Journal for accession number: 0059946 Created on: 2017-02-19 22:09:26 UTC By: Automated Ingest Agent Source: These data were harvested from the Carbon Dioxide Information Analysis Center (CDIAC) Ocean CO2 web service at http://cdiac.ornl.gov/ftp/oceans/LDEO_Database/Version_2012, and accompanying metadata were downloaded from http://mercury.ornl.gov/metadata/ocean/xml/, in accordance with the archival submission agreement between NCEI and CDIAC. Version: 4.4 Updates received on: 2017-02-17 Actions: Updates were received for this data set. These updates were copied into the data/0-data directory of this accession. These updates may provide additional files or replace obsolete files. However, all of the files received prior to this update are available in the preceding version of this accession. The original data and metadata files were transferred to NCEI by an automated process. Another automated process then transferred the original data files to the data/0-data/ directory of this accession. The automated process also extracted the longitude and latitude data from those data files and plotted a sample location map. The original compressed or tar files used to transfer these data from the data provider were discarded after the extraction and validation processes were successfully completed. Files: about/ This directory contains files generated by NCEI with ancillary information about the data submission. 0059946_lonlat.txt - Contains station locations for these data. Each row contains the geographical position where these data were collected (longitude in the left column and latitude in the right column, both in decimal degrees). NCEI may have corrected or omitted geographic positions that seemed to be in error when generating this file. However, NCEI did not change the original data files under the directory data/0-data/. 0059946_map.jpg - Station location map for the data. data/0-data/ This directory contains the original files that were downloaded from CDIAC.

Database should be cited as: Takahashi, T., S.C. Sutherland, and A. Kozyr. 2009. Global Ocean Surface Water Partial Pressure of CO2 Database: Measurements Performed During 1968-2008 (Version 2008). ORNL/CDIAC-152, NDP-088r. Carbon Dioxide Information Analysis Center, Oak Ridge National Laboratory, U.S. Department of Energy, Oak Ridge, Tennessee, doi: 10.3334/CDIAC/otg.ndp088r. Approximately 4.5 million measurements of surface water partial pressure of CO2 obtained over the global oceans during 1968-2008 are listed in the Lamont-Doherty Earth Observatory (LDEO) database, which includes open ocean and coastal water measurements. The data assembled include only those measured by equilibrator-CO2 analyzer systems and have been quality-controlled based on the stability of the system performance, the reliability of calibrations for CO2 analysis, and the internal consistency of data. To allow re-examination of the data in the future, a number of measured parameters relevant to pCO2 measurements are listed. The overall uncertainty for the pCO2 values listed is estimated to be +/- 2.5 uatm on the average. For simplicity and for ease of reference, this version is referred to as 2008, meaning that data collected through 31 December 2008 has been included. CDIAC intends to update this database annually. There are 26 new cruise/ship files in this update. In addition, some editing has been performed on existing files so this should be considered a "V2008" file. Also CDIAC has added a column reporting the partial pressure of CO2 in seawater in units of Pascals. The data presented in this database include the analyses of partial pressure of CO2 (pCO2), sea surface temperature (SST), sea surface salinity (SSS), pressure of the equilibration, and barometric pressure in the outside air from the ship's observation system.
