Dear ODV User: The ODV collection with the latest LDEO pCO2 Database V2011 is now available at http://odv.awi.de/en/data/ocean/ldeo_pco2_data/. Details about the dataset follow below. Reiner Schlitzer This is the LDEO_Database_V2011 pCO2 dataset for use with ODV 4.4.2 or later. ODV collection produced by Reiner Schlitzer, Alfred Wegener Institute (2012-07-18). A description of the dataset can be found in the attached NDP-088_V2011.pdf document. Database should be cited as: Takahashi, T., S.C. Sutherland, and A. Kozyr. 2012. Global Ocean Surface Water Partial Pressure of CO2 Database: Measurements Performed During 1957-2011 (Version 2011). ORNL/CDIAC-160, NDP-088(V2011). Carbon Dioxide Information Analysis Center, Oak Ridge National Laboratory, U.S. Department of Energy, Oak Ridge, Tennessee, doi: 10.3334/CDIAC/OTG.NDP088(V2011). Approximately 6.4 million measurements of surface water pCO2 made over the global oceans during 1957-2011 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 uatm 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 and V2010) 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. |
