PACKAGE DESCRIPTION: This dataset includes discrete sample and profile data collected from NOAA Ship RONALD H. BROWN in the North Atlantic Ocean and South Atlantic Ocean from 2003-06-04 to 2003-08-11. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-113 (CFC-113), CHLOROFLUOROCARBON-12 (CFC-12), DELTA CARBON-13, DELTA CARBON-14, DELTA HELIUM-3, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED ORGANIC CARBON, DISSOLVED OXYGEN, HELIUM, HYDROSTATIC PRESSURE, NEON, NITRATE, NITRITE, Partial pressure (or fugacity) of carbon dioxide - water, Potential temperature (theta), SALINITY, TOTAL ALKALINITY (TA), Total Dissolved Nitrogen (TDN), Tritium (Hydrogen isotope), WATER TEMPERATURE, pH, phosphate and silicate. The instruments used to collect these data include Alkalinity titrator, CTD, Carbon dioxide (CO2) gas analyzer, Coulometer for DIC measurement, Flask with closed headspace for discrete carbon dioxide (CO2) measurement, bottle and spectrophotometer.
These data were collected by Frank J. Millero of Rosenstiel School of Marine and Atmospheric Science, Rik Wanninkhof of NOAA Atlantic Oceanographic and Meteorological Laboratory and Richard A. Feely of US DOC; NOAA; OAR; Pacific Marine Environmental Laboratory as part of the CLIVAR_A16N_2003 data set. CDIAC associated the following cruise ID(s) with this data set: CLIVAR_A16N_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 |
Replicate information: |
Replicate seawater samples were taken from the surface, 1000 m, and bottom Niskin sample bottles and run at different times during the cell. No systematic biases were discerned and the average difference of the samples was 1.0 μmol/kg for surface values; 1.2 μmol/kg for duplicate samples at 1000 m and 1.4 μmol/kg for duplicate samples near the bottom. |
Standardization description: |
The coulometers were calibrated by injecting aliquots of pure CO2 (99.995%) by means of an 8-port valve outfitted with two sample loops that had been calibrated by Kelly Brown, CCN Consulting (Wilke, 1993) |
CRM batch number: |
59 |

Type of titration: |
Single point titration |
Cell type (open or closed): |
Closed |
Curve fitting method: |
The titration system used to determine TA consisted of a Metrohm 665 Dosimat titrator and an Orion 720A pH meter controlled by a personal computer |

pH |
Abbreviation: |
pH |
pH scale: |
Sea Water Scale |
Observation type: |
discrete |
In-situ / Manipulation / Response variable: |
In-situ observation |
Measured or calculated: |
Measured |
Temperature of pH measurement: |
25 |
Detailed sampling and analyzing information: |
Seawater pH was measured using the spectrophotometric procedure (Byrne, 1987) and the indicator calibration of Clayton and Byrne (1993). The indicator was an 8.0-mM solution of m-cresol purple sodium salt (C21H17O5Na) in MilliQ water. |
pCO2 (fCO2) discrete |
Abbreviation: |
fCO2 |
Observation type: |
discrete |
In-situ / Manipulation / Response variable: |
In-situ observation |
Measured or calculated: |
Measured |
Seawater volume: |
500 mL |
Headspace volume: |
80 mL |
Temperature of measurement: |
20deg.C |
Detailed sampling and analyzing information: |
The fugacity of CO2 was measured at a constant temperature of 20deg.C by equilibrating a 500-mL water aliquot in a volumetric flask with a closed headspace.The headspace is circulated through a non-dispersive infrared detector that measures both CO2 and H2O levels. |
Uncertainty: |
The precision of the results is based on comparison of duplicate values and is estimated to be +/-2 uatm or 0.3% |
