The comparison of facies and geochemical records among cores from the Almenara and Benicasim marshes allows to identify changes in water level (Si/Al, Al, Ca) and salinity of the feeding waters (Mg/Al, Na/Al, S/Al). These changes, in turn, represent fluctuations in the position of the saline-fresh groundwater boundary, which can be related to variations in sea level and rainfall. For the last 4000 years, three events recording higher salinity conditions (ca. 3.4 ka BP, ca. 3 ka BP and ca. 1.8 ka BP) are noticeable in the record. Comparison to other studies around the Western Mediterranean basin allows us to correlate these events to arid episodes and to identify their forcing mechanisms. These aridity events are correlative to small falls in solar activity and Surface Sea Temperature (SST) during positive North Atlantic Oscillation (NAO) periods. Despite the small magnitude of these changes, the sensitivity of the system amplified the result providing a conspicuous signal. eng Aridity events during the last 4000 years in Western Mediterranean marshes (Almenara and Benicasim marshes, E Spain) journal article URL https://docta.ucm.es/bitstreams/61277b99-f9ee-444c-869d-e6636468d62d/download File MD5 66cfce967ac62a6a1a94f10aab26c7e2 1626824 application/pdf Aridity events during the last 4000 years in Western Mediterranean marshes (Almenara and Benicasim marshes, E Spain).pdf URL https://docta.ucm.es/bitstreams/4d5f8541-b735-4d4b-ae50-0be79e2133ed/download File MD5 005a752943632288cd25f41765978f63 71642 text/plain Aridity events during the last 4000 years in Western Mediterranean marshes (Almenara and Benicasim marshes, E Spain).pdf.txt
