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: Analysis of 2 replicate analyses (per bottle). For the stand-alone instrument values from the 1st and the 2nd analysis did not show a systematic offset and both values were used. For the Vindta instrument only values for the 1st analysis were used, as DIC of the 2nd analysis was systematically slightly lower than that of the 1st analysis due to outgassing. Nonetheless the repeat analyses on the Vindta provided a useful quality control on the performance of the instrument.; CRM batch number: 90 92.
  • 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 on 2 Vindtas V4 (ID 4) and V7 (ID 7). The alkalinity measurements were made by potentiometric titration with two VINDTA instruments (#4 and #7, version 3C, Mintrop, 2004). The acid consumption up to the second endpoint is equal to titration alkalinity. The systems use a highly precise Metrohm Titrino for adding acid, an ORION-Ross pH electrode and a Metrohm reference electrode. The pipette (volume approximately 100 ml), and the analysis cell have a water jacket around them. The titrant (0.1 M hydrochloric acid, HCl) was made in the home laboratory. Samples on one Vindta (#4) were run, after analysis on the stand-along DIC extractor and warming to 25°C. Samples on the second Vindta (#7) were run for both DIC and alkalinity at 25°C. Replicate analyses were run for all samples on the Vindta #7 and for most samples on the Vindta #4. At least two CRMs of batch 92 or 90 were run per station. TA was calculated in Matlab code by Steven van Heuven, version 33, based on code by Ernie Lewis in QB (1996);; Cell type (open or closed): Open; Curve fitting method: Modified Levenberg-Marquard least squares program; TA blank correction: Acid factor instrument V4: 0.0970 +/- 0.0004 M; instrument V7: 0.0976 +/- 0.005 M for the hydrochloric acid. Both instruments used subsamples of the same acid stock solution. When preparing the solutions we aimed for an acid factor of 0.1M HCl. The accuracy of the calibration of the TA pipette would have contributed to the difference in the average acid factor between both instruments.; Uncertainty: The accuracy of the TA data (with flag 2) has been estimated as 3 µmol/kg for the cruise. The accuracy has been estimated from the average standard deviation of CRMs per acid batch, which was 1 µmol/kg for the western A21 section and 3 µmol/kg for the eastern SR1b section. The precision of the TA sample averages (with flags 2 and 3) has been estimated as 3 µmol/kg for the cruise from the repeatability of 674 pairs of duplicate samples (Dickson et al., 2007, SOP 23). The repeatability was slightly better for Vindta V4 (2.3 µmol/kg, 372 samples) than for Vindta V7 (2.7 µmol/kg, 302 samples). TA data were calibrated with the acid factors, whenever possible per acid batch. Preliminary data showed substantial offsets between neighboring stations, in particular for the second eastern SR1b section for Vindta V4, with Vindta V4 TA data often lower than those for V7. Such offsets between stations were deemed to be unrealistic and an artifact of the analytical procedure. The acid factor of such outlier stations on Vindta V4 was adjusted in order to remove the offset. This correction concerns stations 11 (+5 µmol/kg), 38 (+4 µmol/kg), 39 (+3 µmol/kg), 43 (+2 µmol/kg), 50 (+5 µmol/kg), 54 (+5 µmol/kg), 58 (+8 µmol/kg), 66 (+3 µmol/kg), 70 (+11 µmol/kg), 71 (+3 µmol/kg), 74 (+3 µmol/kg), 78 (+3 µmol/kg), 82 (+3 µmol/kg), and 83 (+3 µmol/kg). These corrections increased TA and, if incorrect, would have biased the TA data high. The TA data from these stations were given WOCE flag 3 (questionable, probably good). Samples with a difference between repeat analyses exceeding 5 µmol/kg have been given flag 3.; Method reference: unpublished TA and DIC data.
