- Sea-level rise and local tidal range changes in coastal embayments: An added complexity in developing reliable sea-level index points Eduardo Leorri Ryan Mulligan David Mallinson Alejandro Cearreta Ciencias de la Tierra estuary Holocene sea level tidal range Atlantic Ocean This paper re-evaluates the late Holocene sea-level reconstructions from Delaware Bay and assesses the possible effect of tidal range changes over the last 4000 years. Previous work suggested that the differences found between the northern and southern areas of the Delaware Bay (USA) could be explained by isostatic rebound. However, our results derived from tidal modeling suggest that at least 25% of this difference could be explained by changes in the tidal range due to amplification or attenuation of tidal waves over shallower bathymetry. Furthermore, indications of large changes of the tidal range over short distances might suggest that integration of sea-level index points from different areas should be performed with caution. New sea-level trend estimates have been calculated at 1.17±0.2 mm yr -1 in the southern area, and 1.55±0.2 mm yr -1 in the north. 2011 artículo científico 1646-8872 https://www.redalyc.org/articulo.oa?id=388340134005 en http://www.redalyc.org/revista.oa?id=3883 Revista de Gestão Costeira Integrada - Journal of Integrated Coastal Zone Management application/pdf Associação Portuguesa dos Recursos Hídricos Revista de Gestão Costeira Integrada - Journal of Integrated Coastal Zone Management (Portugal) Num.3 Vol.11
