  • Parameter or Variable: Dissolved Inorganic Carbon; Abbreviation: TCARBN; Unit: UMOL/KG; Observation type: discrete; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Detailed sampling and analyzing information: All measurements were completed on two Versatile INstrument for the Determination of Titration Alkalinity (VINDTA, version 3C, SN#064 and #065, Marianda, Germany, Mintrop, 2004) each connected to a coulometer (SN135015020 and SN135015019 respectively). Water samples were first analysed for Dissolved Inorganic Carbon (DIC). An excess of phosphoric acid (1M, 8.5%) was added to a calibrated volume of seawater sample to convert all inorganic dissolved carbon to CO2. This CO2 was then transported to the coulometer cell by oxygen-free-nitrogen gas (OfN), which was filtered through soda lime to remove any residual traces of CO2 prior to coming in contact with the recently converted CO2. In the cell, all CO2 is quantitatively absorbed to form an acid that is subsequently titrated via coulometry. See Dickson et al., (2007) SOP #02 for more detailed information.; Standardization description: Initial DIC calibration was done during the cruise for each instrument by correcting all sample data by the difference between the mean of all CRMs. Post-cruise data quality control will include the calibration of the DIC readings for each coulometer cell used during CE17007, identification and removal of errors/outliers and accounting for instrument drift.; CRM manufacturer: Prof A Dickson, Scripps Institute of Oceanography, San Diego, USA; CRM batch number: CRM batch 163 (certified at 2039.49 ± 0.73 for DIC); Method reference: Dickson, A. G., Sabine, C. L., and Christian, J. R. (Eds.) (2007), Guide to best practices for ocean CO2 measurements, PICES Special Publication 3, pp.191; Researcher name: Ute Schuster; Researcher institution: University of Exeter.
  • Parameter or Variable: Total alkalinity; Abbreviation: ALKALI; Unit: UMOL/KG; Observation type: discrete; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Type of titration: Total Alkalinity was measured by potentiometric titration using the same VINDTA machines as for DIC analysis. These systems use a highly precise Metrohm Titrino for acid addition, an ORION-Ross pH electrode, a Metrohm reference electrode and an auxiliary electrode. Similarly to the DIC analysis, the pipette and analysis cell were kept at the same temperature as the samples (25oC) by a water jacket. Hydrochloric acid (0.1M) made to the ionic strength of seawater was used as the alkalinity titrant as described in SOP#3B (Dickson et al., 2007). Alkalinity values were calibrated using replicate analyses taken from the 500mL bottles and CRM batch 163 (certified at 2215.53 kg-1 ± 0.56 for TA). See Dickson et al., (2007) SOP #03 for more detailed information. Post-cruise data corrections will include a recalculation of alkalinities using CTD temperature, salinity and nutrients, and also incorporate a recalibration of the alkalinity pipettes’ volume and temperature sensors. Post-cruise Quality Control will identify and remove outliers and account for drift in the instruments’ alkalinity measurements taken over the course of the cruise.; CRM manufacturer: Prof A Dickson, Scripps Institute of Oceanography, San Diego, USA; CRM batch number: CRM batch 163 (certified at 2215.53 kg-1 ± 0.56 for TA).; Uncertainty: Repeated measurements on the same batch of seawater (n=3) were undertaken every day prior to sample analysis in order to assess the precision of the method. The precision was estimated for the whole dataset to be 3 μmol kg-1 for DIC and 4 μmol kg-1 for TA. The accuracy of the measurement is assured by the standardization using the CRM from A.G.
