Changes to processes in estuaries and coastal waters due to intense multiple pressures:an introduction and synthesis
2015
From the 2013 ECSA conference ‘Estuaries and Coastal Areas in Times of Intense Change’ a theme emerged that has ended up being the focus of this Special Issue of Estuarine Coastal and Shelf Science, namely ‘Changes to processes in estuaries and coastal waters due to intense multiple pressures’. Manyparts of the world are continuing to experience unprecedented rates of economic growth, and those responsible for managing coastal and estuarine areas must respond accordingly. At the same time, global climate change and sea level rise are also continuing, placing new or more intense pressures on coastal areas that must be dealt with in ways that are as far as possible managed as a result of good…
The Brolo Island, a lentil in the “Ocean”
2010
The north-eastern Sicily coast reflects the effects of Holocene active tectonics associated to subduction system of Ionian crust beneath the Calabrian arc (CAPUTO et alii, 1970; WESTAWAY, 1993, DOGLIONI et alii, 1999). The latter, characterized by a stack of crystalline rock and its sedimentary cover, is the highest structural element in the Sicily chain. The Calabrian arc is a region that records one of the major Quaternary vertical tectonic movement in the whole Mediterranean basin. This uplift, well documented from Last Interglacial, is expressed as vertical variation of the height of the Quaternary marine terraces inner margin that characterize the north-eastern Sicily coast. The uplift…
Termini of calving glaciers as self-organized critical systems
2014
Calving margins are highly sensitive to changes in climate and glacier terminus geometry. Numerical modelling suggests that calving glacier termini are self-organized critical systems that are fluctuating between states of advance and retreat. Over the next century, one of the largest contributions to sea level rise will come from ice sheets and glaciers calving ice into the ocean1. Factors controlling the rapid and nonlinear variations in calving fluxes are poorly understood, and therefore difficult to include in prognostic climate-forced land-ice models. Here we analyse globally distributed calving data sets from Svalbard, Alaska (USA), Greenland and Antarctica in combination with simulat…

Didactic proposal to change misconceptions about the contribution of the fusion of the ice to the rise in sea level
2020
En la actualidad existen muchos estudios acerca del conocimiento teórico de la población sobre el cambio climático. Los resultados de estos estudios muestran la existencia de confusiones e ideas alternativas respecto a determinados fenómenos y conceptos básicos de gran importancia, las cuales constituyen un serio obstáculo para el aprendizaje en educación ambiental. En este trabajo se analiza una de esas ideas, relacionada con el impacto directo que tiene la fusión del hielo flotante en el aumento del nivel del mar. Concretamente, se muestra una primera aproximación respecto a su extensión y fortaleza entre alumnado de secundaria y profesorado en formación, detallando a su vez una estrategi…
Late Pleistocene-Holocene coastal adaptation in central Mediterranean: Snapshots from Grotta d’Oriente (NW Sicily)
2018
Marine faunal remains from Grotta d’Oriente (Favignana Island, NW Sicily) offer invaluable snapshots of human-coastal environment interaction in the central Mediterranean from the Late Pleistocene to the Middle Holocene. The long-term shellfish and fish records reflect human exploitation of coastal environments undergoing considerable reorganizations during the postglacial sea level rise and the progressive isolation of Favignana from mainland Sicily. We detected an intensification of marine resource exploitation between ∼9.6 ka and ∼7.8 ka BP, which corresponds with the isolation of Favignana Island and, later on, with the introduction of early agro-pastoral economy in this region. We sugg…
Human settlements in the Mediterranean and the sea level changes from 12 ka to the present
2012
Understanding past sea-level change plays an important role in determining the underlying causes, and also allows the extrapolation of past sea levels to locations and epochs for which there are no instrumental data. A compilation of global sea-level estimates based on deep-sea oxygen isotope ratios at millennial-scale resolution or higher was published since ‘70. These global sea level curves do not take in account isostasy and tectonics. Observed sea level change can be reconstructed from dated fossils, coral reef terraces, speleothems, emerged and forming terraces on coastal areas, archaeological and other markers well connected with sea level. Because of the lack of coral reefs in the M…
Erosión costera y cambio ambiental en el humeral de Cabanes-Torreblanca (Castelló). Datos para una gestión sostenible
2014
A progressive increase in salinity and marine influence, related to local subsidence characterize the evolution of the lagoon of Cabanes Torreblanca. Relative sea level rise, caused saltwater intrusion and landward migration of the barrier. This barrier is recessive (60-20 m in the last 50 years) and its current processes show a sedimentary deficit that can lead to rapid and irreversible changes. The information shown by this research can help to achieve a sustainable management.
The possible influence of sea level rise on the precarious dunes of Devesa del Saler Beach, Valencia, Spain
1991
The Saler Beach dune field in Spain was partially destroyed between 1970 and 1973 due to building development. Presently great efforts to restore some dunes has begun. The possible consequence of a sea level rise for the Saler dune field is discussed according to different scenarios.
