Processing Steps
  • 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; Curve fitting method: Total alkalinity was measured by potentiometric titrations to final pH of 4.40 following Pérez and Fraga 1987. Seawater samples for alkalinity were collected after pH samples, in 600 ml glass bottles. Samples were filled to overflowing and immediately stopped. Total alkalinity was measured using an automatic potentiometric titrator "TITRANDO Metrohm", with a combination glass electrode and a Pt-1000 probe (Metrohm 6.0257.000). The potentiometric titrations were carried out with hydrochloric acid ([HCl] = 0.1 M, Riedel-deHaën, Fixanal 38285).; Uncertainty: The precision of the AT measurements (± 0.34 μmol·kg-1) was calculated analysing 14 samples for reproducibility taken from different Niskin bottles closed at the same level (4815 dbar) at station 0. Besides, the 1011 AT duplicates analyses showed a reproducibility of 0.23 ± 0.44 μmol·kg-1 along the cruise.; Method reference: Pérez, F.F. and F. Fraga. 1987. A precise and rapid analytical procedure for alkalinity determination. Mar. Chem.,21, 169-182.
  • Parameter or Variable: pH; Abbreviation: pH; pH scale: SWS@25C; Observation type: discrete; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Temperature of pH measurement: 25C; Detailed sampling and analyzing information: pH was measured spectrophotometrically following Clayton and Byrne (1993). This method consists on adding a dye solution to the seawater sample, so that the ratio between two absorbencies at two different wavelengths is proportional to the sample pH. Seawater samples for pH were collected at 95 stations after oxygen samples from depth using cylindrical optical glass 10-cm path length cells, which were filled to overflowing and immediately stopped. The indicator was a solution of m-cresol purple prepared in seawater. After sampling all the samples were stabilised at 25C. All the absorbance measurements were obtained in the thermostated (250.2 oC) cell compartment of a SHIMADZU UV-2401PC spectrophotometer. Seawater pH was measured using a double-wavelength spectrophotometric procedure (Byrne, 1987). The absorbance was measured at three different fixed wavelengths (434, 578 and 730 nm) and 75 μl of the dye solution were added to each sample using an adjustable repeater pipette. pH, on the total hydrogen ion concentration scale, is calculated using the following formula (Clayton and Byrne, 1993):.
