For scientists, the continents have been drifting for over a hundred years, since Alfred Wegener presented his mobilist model of the Earth’s crust known as the ‘Theory of Continental Drift’ (TCD). This theory represents a key moment in the history of geological research because the horizontal movements of the Earth’s crust he proposed captured the...

This study represents the first attempt to combine the geomorphological characteristics of the island of Ustica with the human settlements that have been established during prehistory, with the purpose of reconstructing the interactions between communities and the natural environment from the Neolithic to the Middle Bronze Age (6th - 1st millennia...
Article
Full-text available
The study of the past is of fundamental importance in understanding the processes that control the functioning of the Earth System and the interaction between ecosystems, human society and natural variability. The Quaternary scientist produces a variety of proxies derived from the investigation of natural, archaeological and historical records cove...
Conference Paper
Since 2012 the Geoswim programme has been investigating coastal landforms along the Mediterranean rocky shores and their lateral variations, through snorkelling and field surveys. The focus of Geoswim investigation is collecting physical/chemical and ecological data relevant to the evaluation of past to future sea level changes. In spring 2017 we e...
Article
Full-text available
The Mediterranean Basin is characterized by a significant variability in tectonic behaviour, ranging from subsidence to uplifting. However, those coastal areas considered to be tectonically stable show coastal landforms at elevations consistent with eustatic and isostatic sea level change models. In particular, geomorphological indicators—such as t...

Full-text available
This study investigates gravity-induced landforms that populate the North-Eastern coast of Malta. Attention is focused on tens of persistent joints and thousands of boulders associated with deep-seated gravitational slope deformations (DGSDs), such as lateral spreads and block slides. Lateral spreads produce deep and long joints, which partially is...
Article
Full-text available
This study presents a global overview of the submerged speleothems used to reconstruct paleo sea levels and reports new results from two stalactites collected in the Mediterranean Sea. Coastal cave deposits significantly contributed to the understanding of global and regional sea-level variations during the Middle and Late Quaternary. The studied s...

The aim of this study is to demonstrate the advantages of using micro drones in the study of large slow-moving landslides, which are widespread along the northwestern coast of Malta. In particular, attention was given to the inventory and analysis of gravity-induced joints and megaclast deposits at four study sites selected due to the presence of r...
Article
Full-text available
The coasts of the Mediterranean Sea are dynamic habitats in which human activities have been conducted for centuries and which feature micro-tidal environments with about 0.40 m of range. For this reason, human settlements are still concentrated along a narrow coastline strip, where any change in the sea level and coastal dynamics may impact anthro...
Article
Full-text available
The photogrammetric method is widely used in coastal areas and in submerged environments. Time-lapse images collected with unmanned aerial vehicles are used to reproduce the emerged areas, while images taken by divers are used to reproduce submerged ones. Conversely, 3D models of natural or human-made objects lying at the water level are severely a...
Article
We produced a new suite of sea-level data which allowed assessing the Holocene evolution of the Bonifacio Strait, a key coastal sector of the Mediterranean Sea which experienced significant morphological changes since the Last Glacial Maximum. Squeezed between Corsica and Sardinia islands, this strait connects the two major basins of the western Me...
Article
This work deals with recent advances in scientific snorkel surveying, starting from the results of several case studies in the Mediterranean between 2012 and 2018, for a total survey length of 531.4 km, with the aim of illustrating the pros and cons. The snorkel survey method, described here, also called ‘Geoswim’, allows rough-and-ready surveys of...
Article
Full-text available
Boulder detachment from the seafloor and subsequent transport and accumulation along rocky coasts is a complex geomorphological process that requires a deep understanding of submarine and onshore environments. This process is especially interesting in semi-enclosed shallow basins characterized by extreme storms, but without a significant tsunami re...

Tens of sea caves and other coastal karst landforms are to be found along the limestone coast of the Maltese Islands. Most of the sea caves develop around the present-day sea level, such as Blue Grotto, which is one of the widest and most spectacular sea cave on the islands. The Blue Grotto karst system is composed by partially submerged chambers,...

Filfla is an islet located in the southernmost point of the Maltese archipelago, at about 5 km southwest of the main island of Malta. The geomorphological features of Filfla, together with the small rocky islet, Filfoletta, located one hundred metres southwest from Filfla, were strongly affected by human impact, as they were used as shooting ranges...
Article
The continental shelf morphology offshore of western Sicily suggests that during the Last Glacial Maximum (LGM, 20 ka cal BP), two of the Egadi Islands, Favignana and Levanzo, were connected to Sicily by a wide emerged plain, while Marettimo was only separated from the other islands by a narrow channel. We studied the relative sea-level variation f...
Article
Full-text available
The evolution of coastal and transitional environments depends upon the interplay of human activities and natural drivers, two factors that are strongly connected and many times conflicting. The urge for efficient tools for characterising and predicting the behaviour of such systems is nowadays particularly pressing, especially under the effects of...
Article
This paper documents the analysis of a coastal boulder deposit that was recently identified along the northern Adriatic coast (Premantura Promontory, Istria, Croatia). Accumulations of large boulders have not previously been reported in the northern Adriatic, which can be viewed as a semi-enclosed basin. A multidisciplinary approach was used to inv...
