  • 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: no replicate; Standardization description: TIC was later determined using gas extraction and coulometric titration with photometric endpoint detection (Johnson, et al., 1985).; CRM batch number: batch # 134 for the entire cruise.
  • Parameter or Variable: Total alkalinity; Abbreviation: TA; Observation type: discrete; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Cell type (open or closed): open cell; Curve fitting method: Total alkalinity was measured by open-cell potentiometric titration with full curve Gran Point determination using a Titrando dosimat with Tiamo software in conjunction with a sample delivery system built in-house..
  • Parameter or Variable: pH; Abbreviation: pH; pH scale: total; 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: Seawater was analysed for pH according to the spectrophotometric method described in “Guide to best practises for ocean CO2 measurements” SOP 6B, edited by Andrew Dickson. Water was collected from the rosette in 60 mL borosilicate glass tubes, allowing each sample to overflow by at least one volume. Racks of tubes were then placed in a water bath held at 25 °C and allowed to thermally equilibrate for 30 minutes. Each sample was then introduced into a water-jacketed 10 cm quartz cell and 30 µL of the purified indicator dye m-cresol purple added before mixing well. The absorbance of light at the wavelengths 434 and 578 nm was measured with an Agilent photodiode array spectrophotometer and the resulting extinction coefficients at these wavelengths were used to determine the pH of the sample. Measurements were conducted during both night and day shifts and samples were stored in a low temperature incubator at 4 degree C until immediately prior to analysis. The maximum time between sampling and analysis was about 4 hours.; Uncertainty: 0.002.
