CONSERVATION NEEDS FOR THE VERMETID REEFS IN THE MEDITERRANEAN SEA
2015
Vermetid reefs are intertidal bioconstructions typical of many subtropical and temperate coastal areas worldwide. Distributed in the warmest waters of the Mediterranean Sea, the reefs are built by the vermetid gastropod Dendropoma petraeum and the coralline alga Neogoniolithon brassica-florida, two species included in the annexes of the Berna Convention. Vermetid reefs provide a wide set of ecosystem services, such as coastal protection from erosion, regulation of sediment transport and accumulation, serving as carbon deposit and increasing biodiversity at the intertidal level. Despite its vulnerability to several threats, such as pollution, spread of invasive species, ocean acidification a…
Showdown in South America: James Scrymser, John Pender, and United States–British Cable Competition
2004
The British dominated the world's submarine cable business over the second half of the nineteenth century, but they encountered significant challenges in the 1880s and 1890s—especially from James Scrymser, an upstart entrepreneur from New York. Scrymser exploited a strategic gap in the cable system in the Western Hemisphere and became locked in a confrontation along the west coast of South America with John Pender, the leading British cable magnate. Scrymser gained the upper hand in Chile by outmaneuvering Pender and used this victory to expand his operations with the telegraph network that linked South America, North America, and Europe.
Modelling biogeochemical processes in sediments from the north-western Adriatic Sea: response to enhanced particulate organic carbon fluxes
2018
This work presents the result of a study carried out in the north-western Adriatic Sea, by combining two different types of biogeochemical models with field sampling efforts. A longline mussel farm was taken as a local source of perturbation to the natural particulate organic carbon (POC) downward flux. This flux was first quantified by means of a pelagic model of POC deposition coupled to sediment trap data, and its effects on sediment bioirrigation capacity and organic matter (OM) degradation pathways were investigated constraining an early diagenesis model by using original data collected in sediment porewater. The measurements were performed at stations located inside and outside the ar…
Temporal evolution of heavy rainfall in the southern West Africa coastline belt.
2018
The Southern Coastalbelt of West Africa (SCWA) is exposed to recurrent flooding. The two objectives of the study are to show thespecificity of SCWA to heavy rainfall occurrence and to determine the trends of the latter. Daily rainfall data of41 stations in the southern parts of Côte d’Ivoire, Ghana, Togo and Benin for the period 1951–2015 and ClimateHazards Group InfraRed Precipitation data were used. The approach is based on the determination (for eachstation and grid point) of the 95th centile (P95) of precipitations greater than or equal to 1 mm. Results indicatethat rainfall is heavier on the coastal belt than inland (average P95 is 65,4 and 45,5 m/day for coastal and inlandstations res…
“Promenade along the coast: Paul Nash and Dave McKean revisit Dymchurch”
2019
This paper examines the specificity of the coastline as a natural, cultural and medial boundary and interface. It focuses on how the motif of the coastline is depicted and remediated in the works of English artists Paul Nash and Dave McKean: between 1919 and 1925, as he was coming to terms with the aftermath of the First World War, Nash created a series of pictures depicting Dymchurch on the coast of Kent in England; McKean’s 2016 commemorative graphic novel Black Dog: The Dreams of Paul Nash is a biographical exploration of Nash’s youth, of his experience of the war and of his recovery in the immediate post-war period. The interplay between memories of the trenches and the landscape of the…
Maritime-oriented foragers during the Late Pleistocene on the eastern costa del sol (Southeast Iberia): Cueva Victoria (Málaga, Spain).
2022
The Mediterranean coast of Spain is marked by several clusters of Palaeolithic sites: to the south of the Pyrenees, in the area around the Ebro River, in the central part, and on the south coast, one of the southernmost regions in Europe. The number of sites is small compared with northern Iberia, but like that region, the Palaeolithic occupations are accompanied by several rock art ensembles. The archaeological material (both biotic and abiotic resources) and radiocarbon dates presented here were obtained during archaeological fieldwork of professor J. Fortea in the Late Pleistocene deposits in Cueva Victoria, located near the modern coastline and about 150 km north of the Strait of Gibral…

ILLEGAL CONSTRUCTIONS IN COASTAL AREAS. PALERMO’S SEASIDE
2012
Strategies to qualify coastal settings must be focused on the evaluation of seaside even in terms of sustainable tourism increasing. Projecting and operating to realize these aims means: to stimulate an eco-compatible behaviour even through new law instruments aimed to reach quality standards, to activate an ecological net of receptive structures, to realize suistable instruments to periodically monitor places the control the environmental impact. In this way, the present study analyzes the problems of Palermo’s seaside, attacked by urbanization and wild speculation, expressing on the forecast of urban plans and on eco-compatible usage strategies
A Methodological Approach to Determine Sound Response Modalities to Coastal Erosion Processes in Mediterranean Andalusia (Spain)
2020
Human occupation along coastal areas has been greatly increasing in recent decades and, in many places, human activities and infrastructures are threatened by erosion processes that can produce relevant economic and human losses. In order to reduce such impacts and design sound management strategies, which can range from the &ldquo
THE BIO-PROTECTIVE ROLE OF A BIOLOGICAL ENCRUSTATION
2014
Benthic organisms can form a persistent biological layer that mediates processes of rock deterioration and limits the degradation of the underlying surface. In this study we investigated the bioprotective potential of barnacle encrustations against salt weathering processes, and discuss their possible role in enhancing the durability of coastal engineering structures
