abstract: This dataset includes discrete sample and profile data collected during the R/V Pourquoi Pas? OVIDE-14 cruise along the GO-SHIP Section A25 and GEOTRACES GA01 (EXPOCODE 35PK20140515) in the North Atlantic Ocean from 2014-05-15 to 2014-06-30. These data include total alkalinity, pH on total scale, oxygen, temperature, salinity, nutrients and other measurements. The instruments used to collect these data include alkalinity titrator, CTD, bottle and spectrophotometer. These data were collected by Fiz Pérez of Instituto de Investigaciones Marinas de Vigo as part of the Hydrographic Repeat Sections Project data set. The International Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select World Ocean Circulation Experiment (WOCE) hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide, and related parameters.
purpose: Coupled physical oceanography and biogeochemistry study of trace elements and their isotopes in the North Atlantic. Role of the past and present ocean in climate and climate change. The related project is GEOVIDE.

description: Parameter or Variable: Total alkalinity; Abbreviation: TALK; 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.

description: Parameter or Variable: pH; Abbreviation: PH_TOT; 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 25ºC. 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):.

description: spectrophotometer, optical spectrometer, spectrograph or spectroscope An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials.

Instrumentation for the spectral dispersion and isolation of optical radiation (IUPAC Recommendations 1995)". Pure Appl. Chem. IUPAC. 67 (10): 1725–1744. doi:10.1351/pac199567101725. A spectrometer is the general term for describing a combination of spectral apparatus with one or more detectors to measure the intensity of one or more spectral bands."
