Abstract A detailed pollen analysis has been carried out on two sediment cores taken from a marsh area located in the Doñana National Park, southwestern Spain. The studied sedimentary sequences contain a similar late Holocene record of vegetation and climate and show a progressive aridification trend since at least 5000 cal. yr BP, through a decre...

A multidisciplinary study from a number of drilled cores in the Guadalquivir estuary has made possible to identify as many as three extreme wave events and their facies in the 4th millennium BP (A: ~ 4000 cal yr BP, B: ~ 3550 cal yr BP, and C: ~ 3150 cal yr BP). These events, which caused strong erosion in the Guadalquivir sandy barrier and in the...

Una de las características más destacables de las Marismas de Doñana es el gran volumen de agua superficial almacenada en los meses invernales, dando lugar a una gran biodiversidad. Sin embargo estos episodios de abundancia hídrica dejan paso a periodos donde esta brilla por su ausencia, en duras y prolongadas sequías. Al igual que otros elementos...

The geomorphological and stratigraphic study of the marshes of Doñana National Park has revealed neo-tectonic activity during the Late Holocene. Anomalous drainage systems and relict surfaces show alignments in NE-SW and NW-SE directions. Analysis of a 12 m core has allowed the authors to identify coastal formations that are now buried under 6 m of...

... Last but not least, most available palynological analyses along the Western Mediterranean coast are characterised by poor chronological control and/or coarse temporal resolution (>50/100 years between studied samples) for the Iron Age and Antiquity periods (e.g. Azuara et al., 2015;Burjachs et al., 2017;Court-Picon et al., 2010;Ejarque et al., 2016;Jiménez-Moreno et al., 2015;Parra, 2012;Riera-Mora and Esteban-Amat, 1994), which hampers detailed landscape reconstruction and correlation with archaeological data. ...

... 202-213), and the crisis in the Roman province of Baetica in the second and third centuries AD(Sánchez-León 1978;Fernández-Ubiña 1981;Tsirkin 1987; Remesal-Rodríguez 2011, pp. 142-157;Campos-Carrasco et al. 2015).We shall mention the data we have obtained regarding EWEs which occurred successively in the third and second millennia BC(Rodríguez-Ramírez et al. 2014 and2015;Celestino-Pérez et al. 2016;López-Sáez et al. 2018), as well as the data concerning an EWE sometime in the early Roman Imperial period, first to third centuries AD). In addition, we shall present evidence that suggests at least one EWE which took place sometime between the eighth and the fourth century BC and may have severely affected the economic, social, and political nucleus of the realm of Tartessus and, presumably, other aspects of Tartessian culture in lower Andalusia.<A> ...
