BUSCADOR RECOLECTA

The item is made of 2 files, of which 1 is the dataset and the other include detailed information about measures realized.-- 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 MOC2EQ carried out from 5 April to 16 May 2010. 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 809 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, Spanish Projects GHG4MOC (CTM2009-07574-E) and MOC2 (CTM2008-06438-C02-01/MAR) supported by Ministerio de Ciencia e Innovación, and CARBOCHANGE (264879), No

CATARINA_LEG1 Cruise (29SG20120622) carried out on the Research Vessel Sarmiento de Gamboa in 2012, CATARINA (Carbon Transport and Acidification Rates in the North Atlantic). The main objectives are to quantify the changes in circulation and ventilation of the North Atlantic water bodies and their effects on anthropogenic carbon uptake. It is also intended to evaluate the impact of current CO2 emissions based on the production and conservation of calcium carbonate in the North Atlantic, as well as the potential impact of future ocean acidification on calcareous organisms

CATARINA Leg 2 - PALEOACID Cruise (29SG20120724) carried out on the Research Vessel Sarmiento de Gamboa in 2012, he Leg 2 of CATARINA (PALEOACID) cruise aims to retrieve surface and subsurface sedimentary samples from the bottom (Box Corer, Piston Corer y Gravity Corer) of the North Atlantic at around 3000-4000 m depth in several areas currently bathed by different components of the North Atlantic Deep Water (NADW), as the Labrador Sea Water (LSW), Denmark Strait Overflow Water (DSOW) Iceland-Scotland Overflow Water (ISOW) and North-East Atlantic Deep Water (NEADW). Neighbor areas of Gibbs Fracture Zone (GFZ), the main deep passage between the West and East North Atlantic basins are considered priority places to obtain samples. It has been used an Multisensor Core Logger (MSCL) onboard and X-ray equipment that allows to obtain x-rays of the different sections of the core
