AbstractThis 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 May 2013.
DescriptionThis data set includes measurements of water samples collected from 11 water bodies (n = 8 to 30 per water body) between March 2010 and March 2013 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 Analyzer) and total alkalinity (using a Metrohm 794 Titroprocessor following the method described by Mintrop et al. (2000) (http://hdl.handle.net/10261/25136). Dissolved carbon dioxide partial pressure was calculated from pH and total alkalinity using co2sys.xls (Pierrot et al., 2000) (http://cdiac.ornl.gov/ftp/co2sys/CO2SYS_calc_XLS_v2.1/) with the dissociation constants for carbon and sulphate of (Cai and Wang 1998) and (Dickson 1990) (https://doi.org/10.1016/0021-9614(90)90074-Z), respectively.
Atmospheric partial pressure of CO2 (μatm) was obtained from the NOAA (National Oceanic and Atmospheric Administration, USA) monitoring station in Izaña, Spain (Site: IZO, http://www.esrl.noaa.gov/gmd/dv/site/).
Daily measurements of rainfall (mm), air temperature (ºC) and wind speed (m s-1) were provided by a meteorological station located in Lebrija (36º 58’ 35’‘N, 06º 07’ 34’’ W) maintained by the Junta de Andalucia (www.juntadeandalucia.es/agriculturaypesca/ifapa/ria/servlet/FrontController).
Estimates of the areal extent of the water bodies derived via remote sensing (Landsat image archive, (http://landsat.usgs.gov/) within each wetland region of Donana Natural Area are included to allow up-scaling of fluxes to regional air-water C transport rates. A Google Earth .kml file delineating the wetland regions is provided.
The data is provided as [space] delimitated plain text files and Google Earth .kml and .kmz files within a compressed folder that also includes a single README file (in markdown format converted to HTML and PDF) containing a detailed description of the data structure.
