- Caracterización de los flujos de CO2 y los parámetros asociados con el sistema de carbonato en el estuario Río Formoso, Brasil Carlos Noriega Moacyr Araujo Manuel Flores Montes Nathalie Lefèvre Ciencias de la Tierra Brazil CO2 fluxes carbon cycle tropical estuary Nine surface water surveys were performed in the Formoso estuary (Brazil) during 2012-2013 mainly in summer and winter periods and during spring tide. Temporal variations of temperature, salinity, phosphate, silicate, total alkalinity, dissolved inorganic carbon, partial pressure of CO2 (pCO2) and water-air CO2 fluxes were analyzed. Low rates of water-air CO2 fluxes (4.7 ± 8.0 mmol C m-2 d-1) were estimated despite the different climate conditions. pCO2 values ranged from 190 to 988 atm. These values are lower than those observed in other tropical estuaries. CO2 fluxes presented in this study contribute to the characterization of humid tropical estuarine systems, thus filling an important geographical information gap. 2015 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47943353018 es http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.3 Vol.50
