Processing Steps
  • Parameter or Variable: Dissolved Inorganic Carbon; Abbreviation: TCARBN; Unit: UMOL/KG; Observation type: Discrete, bottle; Measured or calculated: Measured; Sampling instrument: Niskin Bottles; Analyzing instrument: The analysis was done by coulometry with two analytical systems (PMEL1 and PMEL2) used simultaneously on the cruise. Each system consisted of a coulometer (CM5015 UIC mc) coupled with a Dissolved Inorganic Carbon Extractor (DICE). The DICE system was developed by Esa Peltola and Denis Pierrot of NOAA/AOML and Dana Greeley of NOAA/PMEL to modernize a carbon extractor called SOMMA (Johnson et al. 1985, 1987, 1993, and 1999; Johnson 1992).; Detailed sampling and analyzing information: Samples for DIC measurements were drawn (according to procedures outlined in the PICES Publication, Guide to Best Practices for Ocean CO2 Measurements) from Niskin bottles into 310 ml borosilicate glass flasks using silicone tubing. The flasks were rinsed twice and filled from the bottom with care not to entrain any bubbles, overflowing by at least one-half volume. The sample tube was pinched off and withdrawn, creating a 6 ml headspace, followed by the addition of 0.12 ml of saturated HgCl2 solution, which was added as a preservative. The sample bottles were then sealed with glass stoppers lightly covered with Apiezon-L grease.; Replicate information: The precision of the two DICE systems can be demonstrated via the replicate samples. A total of 591 duplicates were collected during the cruise accounting for 10.7% of the Niskins sampled. These duplicates were collected as a check of our precision.; CRM manufacturer: Andrew Dickson Laboratory at SIO; CRM batch number: CRM No.159; Poison name: saturated HgCl2 solution; Poison volume: 0.12 mL; Uncertainty: The accuracy of the DICE measurement is determined with the use of standards (Certified Reference Materials (CRMs), consisting of filtered and UV irradiated seawater) supplied by Dr. A. Dickson of Scripps Institution of Oceanography (SIO). The CRM accuracy is determined manometrically on land in San Diego and the DIC data reported to the database have been corrected to this batch 159 CRM value. The CRM certified value for this batch is 2027.14 μmol/kg; Quality flag convention: WOCE quality control flags are used: 2 = good value, 3 = questionable value, 4 = bad value; Method reference: Johnson, K., Wills, K., Butler, D., Johnson, W., and Wong, C.: Coulometric total carbon dioxide analysis for marine studies: maximizing the performance of an automated gas extraction system and coulometric detector, Mar. Chem., 44, 167-187, doi:10.1016/0304-4203(93)90201-X, 1993. 2193.; Researcher name: Robert Castle, Andrew Collins ; Researcher institution: NOAA/AOML, NOAA/PMEL.
  • Parameter or Variable: Total alkalinity; Abbreviation: ALKALI; Unit: UMOL/KG; Observation type: Discrete, bottle; Measured or calculated: Measured; Sampling instrument: Niskin Bottles; Analyzing instrument: Metrohm 665 or 765 Dosimat titrator; Type of titration: potentiometric titration; Cell type (open or closed): open; Detailed sampling and analyzing information: Two titration systems, A and B, were used for measuring TA. Each system used a Metrohm 665 or 765 Dosimat titrator, an Orion 720A pH meter and a custom designed plexiglass water-jacketed closed titration cell [Millero et al., 1993b]. The seawater samples were equilibrated to a constant temperature of 25 +/-0.1C with a water bath (Thermo Haak A10). The water-jacketed cell has a volume of ~200 cm3. Each cell has a fill and drain valve that is electronically activated to increase the reproducibility of the volume of sample. A typical titration recorded the EMF after the readings became stable (deviation less than 0.09 mV) and then enough acid was added to change the voltage a pre-assigned increment (~13 mV). A full titration (~25 points) takes about 20 minutes. The electrodes used to measure the EMF of the sample consisted of a ROSS glass pH electrode (Orion, model 810100) and a double junction Ag, AgCl reference electrode (Orion, model 900200).; Standardization description: The volumes of the cells used were calibrated to +/- 0.03 cm3 in port in San Diego, California before the start of the cruise by multiple titrations using Certified Reference Material (CRM) provided by Dr. Andrew Dickson, Marine Physical Laboratory, La Jolla, California. The certified values for the batches used are given in Table 1Error! Reference source not found. Calibrations of the burette of the Dosimat with water at 25oC indicate that the systems deliver 3.000 cm3 (the approximate value for a titration of seawater) to a precision of +/- 0.0004 cm3, resulting in an error of +/- 0.3 μmol·kg-1 in TA. The reproducibility and precision of measurements are checked using low nutrient surface seawater collected from the ship’s flowing seawater system and CRMs. CRMs were utilized in order to account for instrument drift and to maintain measurement precision. Duplicate samples were collected from the same Niskin bottle and provided additional quality assurance. Duplicates were either measured on the same instrument, A or B, or measured one on each system.; CRM manufacturer: Andrew Dickson Laboratory at SIO; CRM batch number: 129, 146, and 159; Quality flag convention: WOCE quality control flags are used: 2 = good value, 3 = questionable value, 4 = bad value; Method reference: Bradshaw, A. L. and Brewer, P. G., High precision measurements of alkalinity and total carbon dioxide in seawater by potentiometric titration, Mar.
