BUSCADOR RECOLECTA

The 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, This 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, Proyecto CARBOOCEAN (511176GOCE), y proyectos del Ministerio de Ciencia e Innovación (CTM2005/01091-MAR y CTM2008-05680-C02-01), No

CANOA08-SUR Cruise (29SG20081102) carried out on the Research Vessel Sarmiento de Gamboa in 2008, A shallow mesoscale anticyclonic eddy, observed south of the Canary Islands with satellite altimetry, has been intensively studied with multiparametric sampling. The campaign involved multiparametric in situ sampling in the region off NW Africa, from Cadiz to Cape Verde and from the shelf break to the deep ocean: the measurements included hydrographic stations with Conductivity-Temperature-Depth (CTD) casts and water samples from a 24 Niskin-bottle rosette; continuous velocity data down to about 600 m depth with the VM-ADCP; CTD sampling with an undulating Nu-Shuttle platform; and the deployment of drifters drogued at about 100 m depth. These measurements were complemented with remote sensing data (SST and altimetry) for the whole NW Africa region

CANOA-08_NORTE Cruise (29GD20080518) carried out on the Research Vessel García del Cid in 2008, The NORTH campaign was carried out in May 2008 (CANOA08-NORTH) on the northern portion of the Gulf of Cádiz. The objective of the campaign was to study the intrusion of Mediterranean waters in the Gulf of Cádiz, with special emphasis on the structure of a Meddy detected in the area using altimetric data. This campaign used a Lowered Acoustic Doppler Profiler (ADCP) and a microstructure profiler (Turbomap) to study the currents and turbulence associated with the Meddy and in one of the submarine canyons south of the Iberian Peninsula
