Processing Steps
  • Parameter or Variable: Dissolved Inorganic Carbon; Abbreviation: DIC; Observation type: discrete; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Calculated; Replicate information: Duplicate samples were collected from approximately 10% of the Niskins sampled, as a check of our precision. These replicate samples were interspersed throughout the station analysis for quality assurance and integrity of the coulometer cell solutions. The average absolute difference from the mean of these replicates is 1.04 µmol/kg. No systematic differences between the replicates were observed.; Standardization description: Each coulometer was calibrated by injecting aliquots of pure CO2 (99.999%) by means of an 8-port valve (Wilke et al., 1993) outfitted with two calibrated sample loops of different sizes (~1ml and ~2ml). The instruments were each separately calibrated at the beginning of each cell with a minimum of two sets of these gas loop injections and then again at the end of each cell to ensure no drift during the life of the cell.; CRM batch number: 109.
  • Parameter or Variable: Total alkalinity; Abbreviation: TA; Observation type: discrete; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Type of titration: Potentiometric titration; Cell type (open or closed): open cell; Curve fitting method: Non-linear least squares Two-stage, potentiometric, open-cell titration using coulometrically analyzed hydrochloric acid; Uncertainty: Analytical accuracy was assessed by periodic analysis of Certified Reference Materials (CRMs) throughout the cruise. CRMs were analyzed approximately every 24 samples. For this CRM batch, the average offset for system 1 was 1.16 with a standard deviation of 1.24. The average offset for system 2 was 0.21 with a standard deviation of 1.67.; Method reference: "Bates, R.G. Determination of pH. Theory and Practice. A Wiley-Interscience Publication, Second Edition.

  • Parameter or Variable: 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 °C; Detailed sampling and analyzing information: Samples were collected for pH analysis immediately following O2 in the Niskin/Rosette sampling sequence. Seawater samples were collected from the Niskin bottles directly in 10-cm cylindrical optical cells (~30 mL volume) using a section of silicone tubing (about 15 cm long). One end of the silicone tubing was attached to the optical cell and the other end was attached to the nipple of the Niskin bottle. The Niskin bottle nipple was pushed in to initiate flow and the silicone tubing was squeezed to eliminate air bubbles. The optical cell was agitated to eliminate bubbles and, after 15 seconds of sample flow, the cell was capped at one end. The silicone tubing was then detached from the optical cell and, with the water still flowing, the cap was rinsed and used to seal the optical cell. Samples collected this way were not exposed to the atmosphere, and each cell was flushed with approximately three cell volumes of seawater. The samples were collected, taken into the lab, and rinsed with tap water to get rid of salt outside of the cells. The cells were dried and the optical windows were cleaned with Kimwipes. Samples were thermostatted at 25 (±0.05) ºC in a custom made 36-position cell warmer. A custom macro program running on Agilent ChemStation was used to guide the measurements and data processing. The macro automated the procedures of sample input, blank and sample scans, quality control, and data archiving. The quality control steps included checking the baseline shift after dye injection and monitoring the standard deviation of multiple scans. Absorbance blanks were taken for each sample and 10 microliters of purified m-cresol purple (10 mmol/kg) were added for the analysis. pHT (total scale) was calculated according to Liu et al. (2011).; Uncertainty: Precision was equal to ±0.0004..
