Recent environmental evolution of regenerated salt marshes in the southern Bay of Biscay: Anthropogenic evidences in their sedimentary record

Agricultural fingerprints in salt-marsh sediments and adaptation to sea-level rise in the eastern Cantabrian coast (N. Spain)

“…The lower part of the estuary presents normal marine salinity values throughout the year (31-42 psu), while the salinity of the middle and upper sections of the systemvary seasonally from 1-25during winter to 27-40during summer, essentially following rainfall regimes (Cearreta, 1988). See Cearreta et al (2002Cearreta et al ( , 2013 for details on the Plentzia and Urdaibai estuaries, respectively.…”

Managed Realignment : A Viable Long-Term Coastal Management Strategy?

“…In the USA and France there are In France, Spain and Portugal restoration of tidal flow into embanked areas occurs mainly as a result from accidental breaches due to storms or natural decay of abandoned defences (e.g. Cearreta et al, 2013;Almeida et al, 2014). In many cases, there is the view that restoration of natural habitat under these conditions produces similar results to managed 124 realignment (e.g.…”

“…In many cases, there is the view that restoration of natural habitat under these conditions produces similar results to managed 124 realignment (e.g. Cearreta et al, 2013). The literature suggests that the vegetation structure of restored saltmarshes is likely to differ from natural systems (Zedler and Adam, 2002;, even after time-frames of 50-100 years (Garbutt and Wolters, 2008;.…”

Environmental Evolution of the Caravelas Estuary (Northeastern Brazilian Coast, 17° S, 39° W) Based on Multiple Proxies in a Sedimentary Record of the Last Century

“…However, it is difficult to obtain conclusive information on anthropogenic impacts by only comparing modern coastal ecosystems, since the majority of coastal areas are impacted in some way by human activities (Debenay and Fernandez, 2009). The use of sedimentary records, where sediments have been continuously deposited since at least preindustrial periods, has proved to be a successful method for assessing anthropogenic impacts throughout the last century, contributing to an understanding of the history of metal inputs (Cearreta et al, 2011;Debenay and Fernandez, 2009;Fichez et al, 2005) and nutrient enrichment (Tsujimoto et al, 2008), among other pollutant sources.…”

“…A combined approach using sedimentological, geochemical, and benthic foraminiferal analyses has been successfully applied in studies in coastal systems with the aim of understanding the impacts of human activities (e.g., Cearreta et al, 2000Cearreta et al, , 2002Cearreta et al, , 2011Thibodeau, de Vernal, and Mucci, 2006).…”
