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; Detailed sampling and analyzing information: A total of 780 seawater samples from whole number stations 3-28 on the AR7W and 2-19 on the XHL were collected in 500 mL borosilicate glass bottles and preserved with mercuric chloride following the method described in “Guide to best practises for ocean CO2 measurements”. The samples were subsequently transported back to the Bedford Institute of Oceanography for analysis. TCO2 was later determined on shore using gas extraction and coulometric titration with photometric endpoint detection (Johnson, et al., 1985).; CRM batch number: Batch 134.
  • 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: two-stage open cell acidimetric, potentiometric; Curve fitting method: A total of 780 seawater samples from whole number stations 3-28 on the AR7W and 2-19 on the XHL were collected in 500 mL borosilicate glass bottles and preserved with mercuric chloride following the method described in “Guide to best practises for ocean CO2 measurements”. The samples were subsequently transported back to the Bedford Institute of Oceanography for analysis. 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 hydrogen ion concentration scale (mol/kg-sw); 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 for pH analysis were collected from every depth at Stations 3 – 28 on the AR7W line, and from every depth at stations 2-19 on the XHL. In addition, samples were collected from selected depths at shallow biological stations on the AR7W and Extended Halifax Lines where the SeaBird pH sensor was deployed. 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 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 °C until immediately prior to analysis. The maximum time between sampling and analysis was about 4 hours. The sample absorption spectra were not referenced to a Certified Reference Material as in the past due to the current unavailability of these CRMs. A total of 623 pH samples were analysed from the AR7W line and 342 from the Extended Halifax Line..
