CitationDiscrete measurements of CO2 and hydrographic data during the R/V Hesperides P3A2 cruise in Gulf of Cadiz and Strait of Gibraltar (October 6 - 12, 2008) [Dataset], 2013
AbstractThis dataset gathers discrete measurements of CO2 (pH and alkalinity) and hydrographic variables (salinity, temperature, dissolved oxygen, nitrate, phosphate and silicate) obtained during the cruise P3A22008. carried out in the Strait of Gibraltar from 6 to 12 October 2008
pH was measured spectrophotometrically following the Clayton and Byrne (1993). This method consists on adding a dye solution to the seawater sample, so that the ratio between two absorbances at two different wavelengths is proportional to the sample pH. Alkalinity was measured using an automatic potentiometric titrator Titrando 794 Metrohm, with a Metrohm 6.0232.100 combination glass electrode and a Pt-1000 probe for temperature measurement following the methodology given by Pérez and Fraga (1987). Dissolved oxygen was analyzed following the widely applied Winkler method. Determinations of nitrate, phosphate and silicate were carried out following methods described by Hansen and Grassoff (1983) Salinity and Temperature were recorded with a CTD probe
DescriptionThe item is made of 2 files, of which 1 is the dataset and the other includes a small description of the measured variables.-- Dataset contributed to the Project Carbochange
