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), Clivar_A06_2010.exc.csv.-- Report_MOC2EC_2010.pdf.-- Readme_Clivar_A06_2010.txt, Peer reviewed

The pH was measured potentiometrically in the NBS scale with a combined glass electrode associated to a thermo-compensator and referred to 15ºC (Perez and Fraga, 1987a). The method had a shipboard precision of 0.005 units, based on 184 replicate analysis corresponding to two different oceanographic bottles fired at the same depth at each station (Ríos and Rosón, 1996). AT measurements were made by titration of seawater with potentiometric endpoint detection (Perez and Fraga, 1987b), reaching a precision of ±1 µmol kg-1. 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, Instituto Español de Oceanografía y Comisión Interministerial de Ciencia y Tecnología (CICYT), Hesperides_1992.csv.-- Readme_Hesperides_1992.txt, Peer reviewed

This dataset will be permanently stored in Digital.CSIC. This DataSet is in Idrisi Raster Format and in latlong projection., This dataset is an archive of gridded surfaces of mean maximum, mean and mean minimum temperature, and precipitation, for the Iberian Peninsula. Temporal resolution is of 1 month, and spatial resolution is of 0.0089999994 degrees. The study area ranges from 43.8969994ºN through 35.5000000ºN, and from 9.6999998ºW through 3.5029993ºE. It covers continental Spain and Portugal. There is a total of 1920 grids (40 years x 12 months x 4 variables). The surfaces were interpolated using ANUSPLIN on georeferenced climate records drawn from the Spanish State Agency of Meteorology and the Portuguese Water Resources Information System. Variable networks of input stations were used to interpolate the surfaces, averaging 390 and 1877 points for temperature and precipitation respectively. A fixed configuration was used for all the interpolations: trivariate quadratic spline model with longitude, latitude and elevation as independent variables. A square root transformation was appied to precipitation fields to reduce skewness. The software was made to minimize the Generalized Cross Validation (GCV) error. The signal to data point ratio was below 50% for temperature surfaces, with many values between 25% and 35%. This suggests limitations in the number of input data points which may have resulted in a loss of detail on the interpolated surfaces. This is not necessarily bad in terms of broad spatial patterns, but it does indicate that absolute predictions should be used with caution for fine microclimatic patterns. Root generalized cross validation was usually lower than 1ºC for temperature, reaching up to 0.85ºC for summer months of mean maximum temperature. Absolute errors in precipitation did range from 4.41 mm in July to 12.82 mm in December, but the seasonal pattern of prediction errors was inverse and corresponded to 24% and 13% respectively., The following projects have funded this package: DeSurvey IP (ECFP6 Integrated Project contract No. 003950), DesertWatch (ESA DUE contract No. 18487/04/I-LG) and MesoTopos (Junta de Andalucia PE ref.
