                description:  Parameter or Variable: Total alkalinity; Abbreviation: ALKALI; Unit: UMOL/KG; Controlled vocabulary name: Total alkalinity; Observation type: Bottle discrete; In-situ / Manipulation / Response variable: in-situ; Sampling instrument: Niskin Bottles; Detailed sampling and analyzing information: Total alkalinity was determined by titration of seawater using a potentiometric system as described in Pérez et al. (CCMM, 2000) with a Metrohm 794 Titoprocessor. Water samples were taken from the Niskin bottles in 500 mL borosilicate bottles and poisoned with 100 μL of a saturated aqueous solution of mercuric chloride for later shore-based analysis. The accuracy of the AT determination was assessed by regular measurements of Certified Reference Material (CRM, supplied by Prof. Andrew Dickson, Scripps Institution of Oceanography, La Jolla, CA, USA).; Researcher name: E. Huertas (ICMAN CSIC).

                description:  Parameter or Variable: pH on total scale at measured T 25ºC; Abbreviation: PHTS25P0; Controlled vocabulary name: pH; Observation type: Bottle discrete; In-situ / Manipulation / Response variable: in-situ; Detailed sampling and analyzing information: The pH was measured following the spectrophotometric method of Clayton and Byrne (1993) using m-cresol purple as indicator, and consequently, the scale used was total. Samples were collected directly from the rosette in 10cm path-length optical glass cells and measurements were carried out on board with a Shimadzu UV-2401PC spectrophotometer containing a 25ºC-thermostated cells holder. Seawater, also previously thermostated to 25ºC, was analyzed for a blank determination at 730, 578 and 434 nm and 50 μl of the dye was subsequently injected and the measurements repeated. Three photometric replicates were carried out for each injection in order to remove any dye effect. The method has a precision of ±0.003 pH units and measurements were shown to be internally consistent with other carbon dioxide measurements by using the above mentioned certified reference materials.; Researcher name: E. Huertas (ICMAN CSIC) .
