These data include total alkalinity, pH on sea water scale, oxygen, temperature, salinity, nutrients and chlorofluorocarbons. The instruments used to collect these data include alkalinity titrator, CTD, Niskin bottles and spectrophotometer. The International GO-SHIP Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters. The objectives of the OVIDE-16 cruise are fulfilled in spite of the problems derived from the installation of the new signal transmission cable. This operation delayed the departure by one week. However, this delay was recovered thanks to the speed of the ship, the constant adaptation of the cruise planning to the weather forecasts and the excellent reliability of the CTD and box- corer operations. A total of 138 CTD stations and 66 sediment sampling were done. In addition, the recovery and new deployment of two ASFAR-ARGO systems were done, as well as the deployment of five meteorological floats and nine ARGO floats.

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.

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): Parameter or Variable: CTDTMP; Abbreviation: CTDTMP; Unit: DEG_C; Controlled vocabulary name: WATER TEMPERATURE; In-situ / Manipulation / Response variable: in-situ observation Parameter or Variable: CTDSAL; Abbreviation: CTDSAL; Controlled vocabulary name: SALINITY; In-situ / Manipulation / Response variable: in-situ observation Parameter or Variable: SALNTY; Abbreviation: SALNTY; Controlled vocabulary name: SALINITY; In-situ / Manipulation / Response variable: in-situ observation Parameter or Variable: OXYGEN; Abbreviation: OXYGEN; Unit: UMOL/KG; Controlled vocabulary name: DISSOLVED OXYGEN; In-situ / Manipulation / Response variable: in-situ observation Parameter or Variable: SILCAT; Abbreviation: SILCAT; Unit: UMOL/KG; Controlled vocabulary name: silicate; In-situ / Manipulation / Response variable: in-situ observation Parameter or Variable: NITRAT; Abbreviation: NITRAT; Unit: UMOL/KG; Controlled vocabulary name: NITRATE; In-situ / Manipulation / Response variable: in-situ observation Parameter or Variable: Phosphate; Abbreviation: PHSPHT; Unit: UMOL/KG; Controlled vocabulary name: PHSPHT; In-situ / Manipulation / Response variable: in-situ observation Parameter or Variable: PH_TMP; Abbreviation: PH_TMP; Unit: DEG_C; Controlled vocabulary name: pH; In-situ / Manipulation / Response variable: in-situ observation Parameter or Variable: Chlorofluorocarbons (CFC-11, CFC-12); Abbreviation: CFCs; Unit: PMOL/KG; Controlled vocabulary name: Potential temperature (theta); In-situ / Manipulation / Response variable: in-situ observation asNeeded Metadata are developed, maintained and distributed by NCEI.
