PACKAGE DESCRIPTION: This dataset includes chemical, discrete sample, physical and profile data collected from KNORR in the Caribbean Sea and North Atlantic Ocean from 2003-09-22 to 2003-11-13. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-113 (CFC-113), CHLOROFLUOROCARBON-12 (CFC-12), Carbon tetrachloride (CCL4), DELTA CARBON-13, DELTA CARBON-14, DELTA HELIUM-3, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED ORGANIC CARBON, DISSOLVED OXYGEN, HELIUM, HYDROSTATIC PRESSURE, NEON, NITRATE, NITRITE, Potential temperature (theta), SALINITY, TOTAL ALKALINITY (TA), Total Dissolved Nitrogen (TDN), Tritium (Hydrogen isotope), WATER TEMPERATURE, phosphate and silicate. The instruments used to collect these data include Alkalinity titrator, CTD, Coulometer for DIC measurement and bottle.
These data were collected by Frank J. Millero of Rosenstiel School of Marine and Atmospheric Science, Richard A. Feely and Christopher Sabine of US DOC; NOAA; OAR; Pacific Marine Environmental Laboratory and Andrew Dickson of University of California - San Diego; Scripps Institution of Oceanography as part of the CLIVAR_A20_2003_CARINA_316N20030922 and CLIVAR_A22_2003, CARINA/316N20031023 data set. CDIAC associated the following cruise ID(s) with this data set: CLIVAR_A20_2003 and CLIVAR_A22_2003
The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.

VARIABLES / PARAMETERS:
Dissolved Inorganic Carbon |
Abbreviation: |
DIC |
Observation type: |
discrete |
In-situ / Manipulation / Response variable: |
In-situ observation |
Measured or calculated: |
Calculated |
Detailed sampling and analyzing information: |
The TCO2 analysis was done by coulometry with two analytical systems (PMEL-1 and PMEL-2) used simultaneously on the cruise. Each system consisted of a coulometer (UIC, Inc.) coupled with a SOMMA. |
Standardization description: |
The coulometers were each calibrated by injecting aliquots of pure CO2 (99.995%) by means of an 8-port valve outfitted with two sample loops. The instruments were calibrated at the beginning and end of each station with a set of the gas loop injections. |

Abbreviation: |

Observation type: |
discrete |
In-situ / Manipulation / Response variable: |
In-situ observation |
Measured or calculated: |
Measured |
Type of titration: |
Single point titration |
Cell type (open or closed): |
Closed |
Curve fitting method: |
The titration systems used to determine TAALK of a Metrohm 665 Dosimat titrator and an Orion 720A pH meter that is controlled by a personal computer (Millero, et al., 1993b). Both the acid titrant in a water jacketed burette and the seawater sample in a water jacketed cell were controlled to a constant temperature of 25degC with a Neslab constant temperature bath. |
Uncertainty: |
The precision of the fit is better than 0.4 μmol/kg when pK1 is allowed to vary and 1.5 μmol/kg when pK1 is fixed. |
