RT Journal Article T1 Variación estacional de los contenidos en carbono orgánico, inorgánico y azufre en los sedimentos del estuario de los ríos Tinto y Odiel (SO España) T1 Seasonal variation of the organic carbon, inorganic carbon and sulfur contents in sediments of the Odiel and Tintoriver estuary (SW Spain) A1 López González, Nieves A1 Borrego Flores, José A1 Morales González, Juan Antonio A1 Carro Flores, Berta AB The study of 12 sediment traps located in the Tinto and Odiel river estuary show the influence of the acidcontributions in the seasonal variation of the contents in organic carbon, inorganic carbon and sulfur. Theseasonal relations between organic carbon and sulfur (C/S) have allowed determining environmentalconditions of the estuarine system. Of this form, the winter conditions correspond to a normal marineenvironment, whereas rest of the year varies between euxinic and semi-euxinic conditions due to the highrate of evaporation that takes place in the intertidal zone that favors sulphate precipitation PB Sociedad Geológica de España YR 2006 FD 2006 LK http://hdl.handle.net/10272/8644 UL http://hdl.handle.net/10272/8644 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
