PACKAGE DESCRIPTION: This dataset includes chemical, discrete sample, physical and profile data collected from NOAA Ship DISCOVERER in the Gulf of Alaska and North Pacific Ocean from 1991-03-07 to 1991-04-07 and retrieved during cruise WOCE_P16N_CGC91. These data include ALKALINITY, 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, Potential temperature (theta), SALINITY, SILICATE, Tritium (Hydrogen isotope), WATER TEMPERATURE and pH. The instruments used to collect these data include CTD and bottle. These data were collected by Richard A. Feely and John L. Bullister of US DOC; NOAA; OAR; Pacific Marine Environmental Laboratory as part of the WOCE_P16N_CGC91 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
Detailed sampling and analyzing information: The TCO2 concentration of seawater samples was determined by using the coulometric titration system (UIC Inc., Model 5011) described by Johnson et al. (1985, 1987). The standards used were Na2CO3 in a matrix of 0.7M KCl, and were analyzed daily.
CRM batch number: 1
pH
Abbreviation: pH
pH scale: total pH scale
Observation type: discrete
In-situ / Manipulation / Response variable: In-situ observation
Measured or calculated: Measured
Temperature of pH measurement: 25C
Detailed sampling and analyzing information: Sample cells (10-cm pathlength spectrophotometric cells, 30-cm3 volume) were filled directly from the NiskinTM-type bottle using a 20-cm length of silicone tubing. A flushing volume of approximately 300 mL was used. Care was taken to eliminate bubbles from the sampling system, and the sample cell was sealed with PTFE caps while ensuring that there was no head space. All spectrophotometric pH measurements were made using the indicator m-Cresol Purple. Spectrophotometric cells were warmed to 25CC within the water bath of a refrigerated thermocirculator. Subsequently cells were cleaned and placed in the thermostated sample compartment of the spectrophotometer. Absorbance measurements were made at three wavelengths: a non-absorbing wavelength (730 nm) and wavelengths corresponding to the absorbance maxima of the alkaline (I2-, 578 nm) and acidic (HI-, 434 nm) forms of the indicator.
