Summary
Abstract:
[Summary adopted from the NDP-062 documentation] The Numeric Data Package NDP-062 consists of measurements of total carbon dioxide (TCO2), total alkalinity (TALK), and radiocarbon (delta14C), as well as hydrographic and chemical data, taken during the Research Vessel (R/V) ... Thomas Washington Expedition TUNES-1 in the Equatorial Pacific Ocean (Section P17C). Conducted as part of the World Ocean Circulation Experiment (WOCE), the cruise began in San Diego, California, on May 31, 1991, and ended in Papeete, Tahiti, on July 11, 1991. WOCE Meridional Section P17C, along 135 W and between ~5 S and 36 N, was completed during the 42-day expedition. All 123 hydrographic stations (including 9 large-volume stations) were completed to the full water-column depth. Spacing between stations was 30 nautical miles, except between 3 N and 3 S, where it was 10 nautical miles. At 30 stations, CO2 measurements were provided for the U.S. Department of Energy's Carbon Dioxide Program. Hydrographic and chemical measurements made along WOCE Section P17C included pressure, temperature, salinity, and oxygen (measured by conductivity, temperature, and depth sensor), as well as bottle measurements of salinity, oxygen, phosphate, nitrate, nitrite, silicate, chlorofluorocarbon (CFC)-11, CFC-12, delta14C, TCO2, and TALK. In addition, potential temperatures were calculated from the measured variables. The data set is available, free of charge, as a numeric data package (NDP) from the Carbon Dioxide Information Analysis Center. The NDP consists of two oceanographic data files; two FORTRAN 77 data-retrieval-routine files; a documentation file; and this printed report, which describes the contents and format of all files and the procedures and methods used to obtain the data. CDIAC has provided an anonymous FTP area to all data files, retrieval codes, and descriptive files for the NDP's that are presently available. The FTP address for the ndp062 database is: ftp://cdiac.esd.ornl.gov/pub/ndp062 and http://cdiac.ESD.ORNL.GOV/epubs/ndp/ndp062/ndp062.html

Quality
An important part of the NDP process at the Carbon Dioxide Information Analysis Center (CDIAC) involves the quality assurance (QA) review of data before distribution. To guarantee data of the highest possible quality, CDIAC conducts extensive QA reviews that involve examining ... the data for completeness, reasonableness, and accuracy. Although they have common objectives, these reviews are tailored to each data set and often require extensive programming efforts. In short, the QA process is a critical component in the value-added concept of supplying accurate, usable data for researchers. For complete details on the quality analysis done on the NDP-062 data set, see the NDP-062 documentation in: http://cdiac.ESD.ORNL.GOV/ftp/ndp062/
