CO2, Hydrographic, and Chemical Data Obtained During the R/V Thomas Washington Cruise TUNES-1 in the Equatorial Pacific Ocean, CDIAC/NDP-062Entry ID: CDIAC_NDP062
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
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:

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/
