PACKAGE DESCRIPTION: This dataset includes chemical, discrete sample, physical and profile data collected from KNORR in the South Pacific Ocean and Tasman Sea from 1992-05-02 to 1992-07-30 and retrieved during cruise 316N138_3, 4 and 5. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), DELTA CARBON-13, DELTA CARBON-14, DELTA HELIUM-3, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HELIUM, HYDROSTATIC PRESSURE, NEON, NITRATE, NITRITE, PHOSPHATE, Partial pressure (or fugacity) of carbon dioxide, Potential temperature (theta), SALINITY, SILICATE, Tritium (Hydrogen isotope) and WATER TEMPERATURE. The instruments used to collect these data include CTD and bottle. These data were collected by Douglas Wallace of Universitat Kiel; Institut Fur Meereskunde; Forschungsbereich Marine Biogeochemie and Kenneth Johnson [affiliation unknown] as part of the WOCE_P06 data set.
The World Ocean Circulation Experiment (WOCE) was a major component of the World Climate Research Program with the overall goal of better understanding the ocean's role in climate and climatic changes resulting from both natural and anthropogenic causes. The CO2 survey took advantage of the sampling opportunities provided by the WOCE Hydrographic Program (WHP) cruises during this period between 1990 and 1998. The final collection covers approximately 23,000 stations from 94 WOCE cruises.

VARIABLES / PARAMETERS:
Dissolved Inorganic Carbon |
Abbreviation: |
DIC |
Observation type: |
discrete |
In-situ / Manipulation / Response variable: |
In-situ observation |
Measured or calculated: |
Calculated |
Replicate information: |
The sample precision calculation includes the results for some samples (K = 13) that were analyzed in triplicate (i.e., two replicates analyzed on one system and the third on the second system). For these cases, the mean of the two replicate analyses was used for calculating Sp2. Averaging the replicate results reduced the degrees of freedom term by making n = 1 for each system no matter how many replicates were actually run on each system. |
Standardization description: |
Samples were collected in 300-mL precombusted (450C for 24 h) glass standard Biological Oxygen Demand (BOD) bottles, poisoned with 200-ul of a 50% saturated solution of HgCl2, and analyzed for TCO2 within 24 hours of collection (DOE Hand Book of Methods, 1994). |
CRM batch number: |

Abbreviation: |

Observation type: |

In-situ / Manipulation / Response variable: |

Measured or calculated: |

Seawater volume: |
55 mL |
Headspace volume: |
5 mL |
Temperature of measurement: |
20 degree C |
Detailed sampling and analyzing information: |
Samples for discrete pCO2 analyses were collected by overfilling 60-mL precalibrated serum bottles in the same manner as for oxygen and TCO2. |
Sample replicate information: |
the pooled standard deviation (Sp2) for pCO2, calculated according to Youden (1951) where K was the number of samples with duplicates analyzed (n = 2), n was the total number of replicates analyzed from K samples, and n - K was the degrees of freedom (d.f.); |
Temperature correction method: |
thermostatted shaking water bath and equilibrated |
Uncertainty: |
In all, duplicates for 109 of the 808 pCO2 samples were taken during WOCE Section P6. Based on these samples, the sample precision (Sp2) for pCO2 was +/-17.4 uatm. Because of the large dynamic range of the pCO2 measurements (>1000 µatm), the geometric mean of the Rel. S. D. was considered to be the best measure of overall sample precision on a percentage basis (+/-0.88%). For the derived variable TALK the sample precision (Sp2) was +/-3.39 μmol/kg and the Rel. S. Dev. [(Sp2 / mean) - 100] was 0.14%. The corresponding result for TCO2 is approximately 0.08%. |
