This data set includes measurements of water samples collected from 11 water bodies (n = 6 to 12 per water body) between March 2010 and March 2011 within Doñana Natural Area. Geographic coordinates of sampling positions and a Google Earth .kml file are provided. Approximately every 30 days in situ water conductivity (converted to salinity), temperature and pH were measured using a multi-probe (YSI-6920V2, YSI Incorporated, Yellow Springs, Ohio, USA) and filtered water samples were collected for laboratory analysis of dissolved phosphate, silica (using a Skalar San++ 215 Continuous Flow Analyser) and total alkalinity (using a Metrohm 794 Titroprocessor following the method described by Mintrop et al. 2000). Dissolved carbon dioxide partial pressure was calculated from pH and total alkalinity using co2sys.xls (Pierrot et al., 2000) with the dissociation constants for carbon and sulphate of (Cai and Wang 1998) and (Dickson 1990), respectively. Carbon dioxide partial pressure in air and daily-ensemble-averaged horizontal wind velocity at 10 m above the land surface were provided by the ICTS Doñana Scientific Reserve (ICTS-2009-39) and are included to allow calculations of air-water fluxes. Estimates of the areal extent of the water bodies derived via remote sensing (DEIMOS-1 and Landsat 5 TM sensors) within each wetland region of Doñana Natural Area are included to allow up-scaling of fluxes to regional air-water carbon transport rates. A Google Earth .kml file delineating the wetland regions is provided and a Google Earth .kmz file showing an indication of the aggregate water coverage derived from the DEIMOS-1 sensor (8 images between Aug 2010 and Sept. 2011) is included to allow qualitative visualization of the areal extent and duration of water coverage. The data is provided as [space] delimited plain text files and Google Earth kml and kmz files within a compressed folder that also includes a detailed data description text file (README_data_description) written using "Simple Markdown" syntax converted to PDF and HTML., This dataset is subject to a Creative Commons License Attribution-Noncommercial-ShareAlike 3.0 Unported. If you use the data, please cite the publication., This data set includes recently published data used to calculate air-water carbon dioxide fluxes within aquatic areas of Doñana Natural Area, SW Spain (Long: -6.373, Lat: 36.932, Datum:WSG84) between March 2010 and 2011., This research was supported by projects P09–RNM–4744 and 049/2010 funded by the Regional Government of Andalucia and the Spanish Ministry for Agriculture, Food and Environment, respectively.

This dataset gathers discrete measurements of CO2 (pH and alkalinity) and hydrographic variables (salinity, temperature, dissolved oxygen, nitrate, phosphate and silicate) in 10 cruises between 2005 and 2007 in the GIFT Time Series Stations located at the Strait of Gibraltar, 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, The item is made of 11 files, of which 1 is the dataset and the other 10 files include detailed descriptions of the data per month of gathering, Dataset contributed to the project Carbochange, CARBOOCEAN, Data are part of the EC-funded Integrated Project CARBOOCEAN - Marine carbon sources and sinks assessment Contract no. 511176 (GOCE), more details available at http://www.carboocean.org/, No
