PACKAGE DESCRIPTION: This dataset includes discrete sample data collected from NATHANIEL B. PALMER in the Southern Oceans from 2011-02-19 to 2011-04-23. 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, SEA SURFACE TEMPERATURE, SULFUR HEXAFLUORIDE (SF6), 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, Coulometer for DIC measurement, bottle and spectrophotometer.
These data were collected by Frank J. Millero and Dennis Hansell 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_S04P_2011 data set.
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: |
The replicate samples (N=314) were interspersed throughout the station analysis for quality assurance and integrity of the coulometer cell solutions. No systematic differences between the replicates were observed |
Standardization description: |
SOMMA (Single Operator Multiparameter Metabolic Analyzer |
CRM batch number: |
Batch 106 |
Total alkalinity |
Abbreviation: |
TA |
Observation type: |
discrete |
In-situ / Manipulation / Response variable: |
In-situ observation |
Measured or calculated: |
Measured |
Type of titration: |
potentiometric |
Cell type (open or closed): |
Open |
Curve fitting method: |
Total alkalinity measurements were made using an open-cell, two-stage, potentiometric titration procedure similar to that used to certify reference materials for total alkalinity (see Dickson et al., 2003), except that samples were not weighed into the titration vessel. |
Uncertainty: |
Precision ~ 1.5 μmol/kg, Accuracy ~ 2.0 μmol/kg |

pH |
Abbreviation: |
pH |
pH scale: |
Total 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: |
pH (mmol/kg H2O) on the total scale was measured using an Agilent 8453 spectrophotometer according to the methods outlined by Clayton and Byrne (1993). A RTE17 water bath maintained spectrophotometric cell temperature at 25.0C. |
Uncertainty: |
The precision of the data can be accessed from measurements of duplicate samples, and certified reference material (CRM) Batch 106 (Dr. Andrew Dickson, UCSD). CRMs were measured approximately every other. The mean and standard deviation for the CRMs was 7.9168+/- 0.0031 (n=110).the accuracy of the pH measurements is underway, and large changes (~0.01) in the final reported values are likely. Confidence in the precision of the measurements remains high, and likely changes would be a simple offset or an offset that is a simple function of reported pH. |
