Abstract: Three zones are differentiated in the marine sector of the Guadalquivir estuary (SW Spain), according to a multidisciplinary analysis (water, sediment, foraminifera). Both salinities and pH increase from the innermost areas (zone 1: Ammonia tepida) to the mouth (zone 3: Ammonia beccarii), with an intermediate zone 2 (Ammonia beccarii-Triloculina trigonula). Both density and diversity are low to very low, except near the transition between zones 2 and 3. Planktonic foraminifera decrease sea Ward from zone 1 to zone 3.
