The time and mode of human dispersal onto Mediterranean islands is a hotly debated question. A multidisciplinary approach combining palaeogeographical reconstructions with biological and archeological evidence is of crucial importance to acquire information on island colonization by Homo sapiens during the Late Pleistocene.
New evidence from Sicily and Sardinia, also using scuba dive and marine geology data demonstrates that, despite being present in the Italian peninsula at least from 43 ka BP, H. sapiens reached the two largest Mediterranean islands no earlier than the LGM. During the Late Pleistocene, a submerged Sill in the Strait of Messina connected Sicily to Europe. Geological, stratigraphic and oceanographic data suggest that the bridge emerged for at least 1,500 years between 21.5 and 20 ka cal BP. This hypothesis is supported by a radiocarbon date on an Equus hydruntinus specimen from San Teodoro cave 21 ka cal BP and archaeological data suggesting that H. sapiens did not arrive to Sicily much earlier than 17.5 ka cal BP. The Egadi Islands, off western Sicily, were not colonized before then either by humans or by terrestrial animals with poor swimming ability.
The hypothesis of a Mid-Pleistocene dispersal on Sardinia by hominins is questionable. H. sapiens remains have been found in early Holocene deposits at Corbeddu cave and S Omu e S Orku respectively 8.7 and 8.5 ka BP, while further evidence is required to support the hypothesis of a presence during the LGM.
We studied a human tooth from Dragonara cave, and a reappraisal of the geological-environmental, confirming with new radiocarbon ages an early Neolithic occupation (7.3 ka BP) of the Portoconte bay.

We present and discuss the genesis, age and evolution of indented landforms carved at sea level in correspondence of carbonatic headlands in three sites of the central Mediterranean coasts, between Marseille (France) and Balzi Rossi (Italy), the island of Tavolara (Sardinia, Italy) and the promontory of Tindari (Sicily, Italy). These landforms can be referred to tidal notch shapes, despite their genesis and morphometric parameters are different from those studied by numerous Authors for the central Mediterranean area. Two of these sites are located in tectonically stable areas, while the third falls in an uplifting area. Those we investigated along the coast of southern France, are Present day submerged notch-type landforms located in the vicinities of current tidal notches. At Tavolara island, these landforms have the shape of "mushroom- type notches" and are placed at about 25 m b.s.l. we propose to relate at MIS 5.3. Finally, those investigated along the metamorphic-carbonatic promontory of Tindari, are marine and abrasional notches, that have been uplifted, likely during the late Holocene.

Careful measurement of the Present day tidal notch geometry coupled to quantitative and qualitative investigation of processes occurring at the intertidal zone in the central Mediterranean Sea has revealed that the genesis of the notch is, rather than the effect of a single mechanism, the result of several processes that concur with different rates to the lowering of the cliff (Antonioli et al., 2015).
Fossil tidal notches in Mediterranean sea (with microtidal condition) are one of the best (or the best) sea level marker. In some coastal areas, despite the dissolution rates on limestones (mean of about 0.02 mm/yr;
Furlani et al., 2009) the MIS 5.5 (aged well with Senegalese fauna deposit at 500 meters) survived because covered by aeolianites. As regard Mediterranean sea there are many problems about the GIA model- calculation for MIS 5.5, for this motive we measured very precisely the base of fossil tidal notch with respect to the base of the Present rut (present sea level, see Fig. 1) or when the cliff are not vertical we used dgps and total station, corrected with local tide. We have operated these measures in 20 sites in the central Mediterranean. The rates vary from 2.12 to 11.52 meters on sea level all measures was taken in stable areas.
Based on these measures we will be propose an innovative geophysical mechanisms (GIA + tectonic) related to the Mediterranean coast.

We sampled and analized a composite speleothem showing together continental, marine and phreatic facies (see Figure 1) in a little cave in the Favignana island. The speleothem show a portion emerged with a carbonatic karstic facies brown coloured, and a white carbonate facies that show phreatic genesis 10 cm thik at -30 cm. Between the two different facies we also noted and analized a marine overgrowth (serpulids). The island is tectonically stable (last interglacia fossil deposit between 5 and 10 metres.
The analisis of carbonatic karst give an age of 19 ka, the marine overgrowth of 1,450 ka cal BP and the last phreatic layr presently submerged of 0.72 ka cal yr BP. E' questo un risultato molto interessante relativo al livello del mare degli ultimi 800 anni, dati del genere sono molto pochi nel Mediterraneo This is an interesting result concerning sea level chenge for the last 700 years, due to the fact that s.l. data are very scarce in the Mediterranean (Toker et al 2013, Pagliarulo et al 2013, Antonioli et al 2016).
The relative sea level at Favignana 0.7 ka BP was at about -30 cm, this value is in agreement with sea level prediction (Lambeck et al 2011, about 5 centimetres over sea-level curve.

We sampled and studied a 30 meters above sea level fossil deposit in the Tuono cave (SE coast of Marettimo, Egadi, Sicily). The outcrop (partially eroded) consists of reddish coarse sands not well cemented containing some bones and a deer jaw with many teeth in excellent condition (Fig X). The fossils are protruding from the sand because the outcrop is eroded at the bottom of the cave by the sea. The fossiliferous sand contains also some Patella Cerulea shells, the fossiliferous sand are on the roof of a well- cemented continental breccia that, in our reconstruction, filled the cave when the sea level was lower than today. As regards the results we provide a radiocarbon age to the Patellae and a tooth the analyses gave the same age: about 8.6 ka cal BP (late Mesolithic). At the light of the importance of these ages we aged (with a different 14C method, using the collagen) a second tooth. But the age was older. We are now discussing the reasons for this and we will provide a new age on last sample. We have interpreted the Patellae shells as a food remain together with the deer tooth, and this would imply an important and novel interpretation for the history of seafaring that for the Mediterranean sea seems to have started with the Neolithic (Mannino et al 2015).

The availability of very high resolution Digital Elevation Models (DEM), represent a main tool for hazards analysis and landscape morphology evolution. During the past years DEMs have been traditionally generated by aerial photogrammetric surveys from aircrafts, providing accurate results by at high costs. The recent developments of ultra-light Unmanned Aerial Vehicles (UAV) open new opportunities on the acquisition of high resolution topographic data from low altitude flights. Therefore acquisition and mapping activities are more cost effective compared to traditional aerial vehicles for airborne based surveys. Here we show results from rapid UAV surveys performed in two nearby areas of the coast between Plemmirio peninsula and Ognina (Sicily), allowing us to obtain the first ultra-high resolution DEM for this area. This coast is part of a tectonically stable region along the vertical for the last 124 ka BP, as inferred from the elevation of the MIS 5.5 terraces. Anyway, during the last decades GPS data and GIA models indicate a diffuse subsidence at rates up to 1 mm/yr. Since this area is undergoing to coastal retreat, land flooding and is exposed to severe storms associated with high-waves, also in consequence of the global sea level rise, we provided a detailed marine flooding scenario for 2100, as generated from: i) high resolution DTM, ii) rate of land subsidence from GPS data and iii) predicted sea level projections from the IPCC Reports (RCP 4.5 and RCP 8.5) and the Veermer and Rahmstorf (2009) dual model. Results should be considered by land managers for a cognizant land management.

Since the last century sea level is rising at unprecedent rates with respect to the last millennia. In the average, the Oceans are rising at 3.2 mm/yr, while the Mediterranean at 1.8 mm/yr. In the latter region,
subsiding coasts, threating coastal infrastructures, heritage sites and cities. The Global Geodetic Observation System (GGOS), is supporting the observation of the natural and anthropogenic coastal changes and, in combination with the IPCC Reports (2014) on of climate change predictions, can be provided marine flooding scenarios for the next decades. With this goal, we have investigated the densely populated coast near Rome, between Fiumicino and Ostia, which is characterized by low elevated coasts, the mouth of Tiber river and important infrastructures, like harbors and the international airport of Fiumicino.
We used and analyzed the available time series of InSAR, GPS and tide gauge data to estimate the rates of land subsidence and sea level trend, to provide the relative sea level rise for this coast up to 2100. Here we show results for two estimated scenarios: i) regional sea level projections of the IPCC for the RCP-4.5 and RCP 8.5 (2014) models and ii) the Veermer and Rahmstorf (2009) dual model. For the most severe scenario, our analysis indicate that a broad area will be flooded by 2100.

A NEW PROPOSAL OF COASTAL GEOMORPHOLOGICAL MAPPING: THE CASE STUDY OF TIBER DELTA

This work has been carried out in the framework of the Working Group (WG) “Coastal Morphodynamics”
of the Italian Association of Physical Geography and Geomorphology (AIGeo), in the wider context of AIGEO cooperation with the Institute for the Protection and Environmental Research (ISPRA) for the updating of the legend for the “Geomorphological Map of Italy”.
The legend has been particularly addressed to coastal zoning of geomorphological hazard and risk situations to support land planning and management. The legend has been down to provide information about the morphological characteristics at small and great detail. The proposed legend represents an upgrade of that one used since the 1994 By “Servizio Geologico Nazionale”.
On the basis of the activities and experiences carried out by the “Coastal Morphodynamics” AIGeo WG, During the last year some examples of coastal geomorphological mapping at different scale (1:5.000 - And 1:25.000) are performed. They have been addressed particularly to the problems both of littoral plain and rocky coast dynamics and to the interactions with anthropic interventions. The tested area on this paper is a part of the wave dominated cuspate Tiber River delta. The delta has two distributary channels: the main one (Fiumara Grande) discharges the 80% of the whole liquid and solid load; the secondary one (Canale Fiumicino) is the evolution of an artificial canal cut in Roman times, and contributes with about the 20% of the liquid and solid discharge. The coastal area is characterized by several beach ridges and small reclaimed depressions under sea level. Drainage canals are present in this area. Urbanization is severe and includes harbour, airport and archaeological sites. The shoreline is protected by hard and soft sea defences.

High-resolution seismic data acquired along the continental shelf/upper slope offshore of Capo Vaticano (western Calabria), Milazzo Promontory and Mt. Etna (eastern Sicily) allow to provide new insights on vertical mobility related to active tectonics. A number of depositional sequences bounded by unconformities or correlative para-conformities were recognized on Sparker profiles in the first 200-300 m below the sea-floor. The most recent sequence overlays a widespread erosional surface that ostensibly formed during the sea level stillstand of the Last Glacial Maximum (LGM), whereas a stack of depositional sequences, which are interpreted as representing the falling and low-stand systems tracts, records older Middle-Late Pleistocene eustatic cycles. In high-resolution seismic profiles the most recent sequence is expressed by well-stratified, laterally continuous, high- amplitude reflectors with typical thickness of 30-40 m. This stacking pattern is typically observed in the central Mediterranean shelf and upper slope affected by vertical tectonic movements (Fraccascia et al., 2013). The magnitude and rate of Late Pleistocene Holocene vertical tectonic movements have been measured on the basis of the present day depth variations of the edges of submerged depositional terraces (and associated abrasion platforms) that formed below the storm- wave base, during the sea level stillstand of the Last Glacial Maximum (LGM). These depositional features, represented by submerged prograding wedges and an associated terrace-shaped upper boundary, identified in the high-resolution seismic reflection, are referred to in this study as
“Lowstand Infralittoral Prograding Wedges (LIPWs)” (Pepe et al., 2014). Our new data and methods provide evidence that LIPWs can be used as geomorphological indicators of vertical movements in offshore settings with well controlled uncertainty. Depending on geodynamic and structural setting, deformation can be related to regional and/or local contribution.

The accumulation of large boulders related to extreme waves, tsunami and storm generated waves, have been observed in different areas of the Mediterranean, such as in the Messina Strait, southeastern Sicily between Siracusa and Augusta, Apulian coasts, Cyprus and recently Malta. On the contrary, the NE Adriatic Sea is considered to be a shallow basin, with very low wave energy.
Moreover, no tsunami boulder deposits were documented. We discovered and mapped, for the first time, the occurrence of four boulder deposits along the southern side of the Istrian Peninsula.
Southern Istria is bordered by rocky coasts, locally limestone slopes at low angles. It is exposed to southern winds, Scirocco, Libeccio with wide fetch. Boulder deposits were discovered in correspondence of flat promontories or ancient quarry pavements.
The widest deposit is about 100 wide and the blocks are scattered on a limestone terrace sloping toward the sea, at an altitude ranging between 0 and 10 m asl. The site represents one of the most suitable area for this type of deposition because of the morphological conditions: most of the NE Adriatic coast is sheltered or dominated by plunging cliffs that prevent the accumulation of wave deposits. This work aims at commence a preliminary surveying of these deposits. The size of the blocks and their location suggest that they are the result of winter storms that often occur along this coastal sector.
The largest block is about (3.4 x 1.6 x 1.15) m in size and has an estimate weight of 10 tonnes.
Most of the blocks, are scattered individually while in some parts of the study area it is possible to find groups of few blocks. Biogenic encrustations have been observed on the blocks, sometimes very recent ones. The largest boulders show typical coastal karst features similar to local coastal features found in the area. This suggests that the detachment area is close to the identified deposits.

MPA managers and scientists are increasingly using Geographic Information Systems (GIS) to manage, map and analyze the resources under the jurisdiction (Pomeroy et al., 2004). The International Union for Conservation of Nature (IUCN) higlights the importance of this system to plan and control the ecological status of MPAs, and to quantify the value, from different points of view such as economic and environmental, of natural heritage present in marine protected areas (Recksiek & Hinchcliff, 2002). GIS can incorporate those data in various forms, including remote sensing, in situ measurements and socio-economic factors. Although this software shows many advantages, it implies to find the spatial localization of each variable within study area and to acquire, analyze and manage huge volumes of data, not always supported by scientific protocols (Di Nora & Agnesi, 2008). Managers of Cyclopean Islands MPA decide to implement the Geographic Information System to satisfy the Ministry requests about the project “Environmental accounting in Italian MPAs” and the European project “Marine Strategy”, entering data relating to flora, fauna and benthos acquired from many different scientific works related to the MPA, in order to compare the values detected by underwater sampling performed in several years, in order to make a balance of the environmental quality of the marine area.

In 2014, the Italian Ministry of the Environment and Protection of Land and Sea funded a 4-years research programme for the implementation of a standardized environmental accounting system for all the twenty-nine Italian Marine Protected Areas (MPAs). The main goals of this research programme are the assessment of the biophysical and economic value of the stocks of natural capital and flows of ecosystem services, and the assessment of environmental costs and impacts due to main human activities performed in the MPAs. Such environmental accounting system will play an important role for the management and monitoring of the MPAs and will support both local managers and policy makers committed to ensure sustainable development and conservation of natural resources in the MPAs.
In this study, the biophysical and economic value of natural capital in two MPAs located in southern Italy, namely “Punta Campanella” and “Isole di Ventotene and Santo Stefano”, was assessed.
MULTIDISCIPLINARY ANALYSIS OF THE ELEUTERIO RIVER BASIN AND THE FACING COASTAL SYSTEM (NORTHERN SICILY). AN ATTEMPT OF ASSESSMENT OF LONG- SHORE MORPHODYNAMIC EVOLUTION

The coastal dynamics is the result of the interplay of different factors affecting the contact area between two main environments: the river basin and the facing coastal system.
The study area (Fig.1) is located in the northern Sicily continental margin (southern Italy) and coincides with the Eleuterio River mouth's and the adjacent beach system. Until fifty years ago the natural setting of this area was a regular succession of sandy-pebbles beaches with rocky coasts and pocket beaches (Lo Iacono et al., 2014); afterwards various coastal facilities were carried out, influencing the natural conditions of the coasts, together with hydraulic structures achieved into the catchment area.
Here we present the results of a multidisciplinary approach aimed to evaluate the river-coast relationships, their respective contribution to the coastal evolution and the hazard scenarios.
Our results showed that this coastal sector is affected by a continuous hydrodynamics, both fluvial and marine, contributing to supplying and distributing sediments. In particular, we applied the Coastal Engineering Research Center (CERC) formula to determine the rate of longshore sand transport (Lo Presti, 2009), while the quantitative geomorphic analysis was used to evaluate the denudation processes into the drainage basin (Cappadonia, 2009) and to calculate the denudation rate index, expressed as suspended sediment yield. We defined also the main longshore transport direction.
The outcomes can be used as a planning tool for the preservation of the coastal environment, related to retraining and management of these areas. Furthermore, it can be used as a tool to guide studies on other integrated systems of the northern Sicily.

GROUNDWATER-FED STREAMS AS REMARKABLE POTENTIAL RECORDS FOR RIVERINE ARCHAEOLOGY AND HOLOCENE SEA-LEVEL CHANGES: THE STELLA RIVER IN FRIULI (NE ITALY)

The alluvial plain stratching along the Southern Alps is characterized by the occurrence of a spring belt (linea delle risorgive in Italian), that marks the passage from the gravels of the proximal fans to the distal portion of the plain, which is dominated by silts and clays. Due to the lack of a mountain catchment, the groundwater-fed rivers are not supplied by solid discharge and, generally, the only sediment they transport consists of the limited material they eroded along the channel (Fontana et al., 2014). This condition allows a unique archeological visibility of the archaeological structures and findings occurring in the channel, that often are cropping out or are covered by a thin layed of mud and riverine vegetation.
Stella River has an average annual discharge of about 40 m3/s and, together with Sile River, represents one of the largest groundwater-fed rivers in Italy and in Europe. The river flows in the Friuli Plain, along the eastern boundary of the Tagliamento alluvial megafans and has its source about 30 km from the Adriatic Coast, while the mouth enters in the Marano Lagoon, forming a little delta. The Stella flow is rather stable along the year and the direct connection of the river with the sea, led it to be prone to sea-level variations, especially in the last 7500 years, when highstand conditions settled (Fontana, 2006).
Water has always influenced also the human settlements, and it is testified by archaeological remains and also current structures, including villages, roads, rural architecture, mansions, “water castles”, mills, farms and other historical buildings that have a productive function (Capulli, 2014).
For these palaeonvironmental, geomomrphological and archaeological reasons, the Stella River was choosen as an important place to establish the project Anaxum: Archaeology and History of a Fluvial Landscape.
Anaxum is the Latin name of the Stella River and the project stems from the partnership between the Department of Humanities and Cultural Heritage of the University of Udine and the Superintendence for the Archaeological Heritage of Region Friuli Venezia Giulia. The main goal is to reconstruct the history of the area, focusing on the relationship between man and the landscape of the Stella River through time. The research is based on the existing documentation, the use of non- invasive methods and the excavation of some targeted areas. Important scientific institutions collaborate to the project, which include Texas A&M University and the Istitute of Nautical Archaeology, for the nautical aspects (Castro and Capulli 2016), University of Trieste and Padua, for the geomorphological and geophysical investigations (Capulli et al., 2013), and the University of Sidney, for the remote sensing.
The project aims to investigate the geomorphology of the riverbed, collecting important data for the gearchaeological reconstruction, but also to study underwater processes and landforms. These are generally not easlily visible and accessible in other large rivers. In several sites, the river channel is eroded in the alluvial deposits dating to Last Glacial Maximum (LGM) and the underwater survey allows to collect stratigraphic information that is normaly available only through boreholes.
The archaeological structures built within the channel or along the banks (e.g. bridge pillars, piers and buildings) can be used as index points or limiting point (cf. Vacchi et al., 2016) for the past relative sea level. In particular, the relict of a Medieval boat, deliberately sunken along the bank near the town of Precenicco, could be used as a minimum indicator for sea level around 11th and 12th century AD.

The use of drones in earth sciences has flourished in the last few years, and in the cases where RPAS (Remotely Piloted Aircraft Systems) have been applied, they gave scientists new insights on ecological, geological and environmental processes. As the technology is relatively new, there are applications that are still poorly explored or completely unexplored. Many of these relate to coastal environments. Coastal areas are subject to rapid changes, often in response to humandriven impulses, and their monitoring at local scale is often necessary to enhance our understanding of a range of different processes such as mechanisms of habitat loss or coastal erosion. Since 2012, we are using drones to study coastal areas and we faced different challenges.
In this presentation, we show 4 applications where drones provide useful information to study coastal environments. In the first application, we introduce an ongoing project on the East coast of Ghana subject to a dramatic coastal erosion where drones are used together with a photogrammetric suite to reconstruct the topography of the emerged beach. In the second application, we show a case where the drone data are used to set up a wave run-up model to study the impact of swells along a low-lying coast in the Ligurian Region (Italy). In the third application, drones and photogrammetry are used on a shallow water environment to reconstruct a coral reef in Moorea (French Polynesia). In the last application, we show the use of drone to reconstruct the
volume of boulders in Bahamas in order to infer the type of sea storm that deposited them on top of a 10-meter cliff.

DISCOVERING A VERY ACTIVE FAULT OFF POZZILLO COAST OFFSETTING THE UNDERWATER EXTENSION OF THE MT. ILICE HISTORICAL LAVA FLOW (ETNA VOLCANO, ITALY)
1Cavallaro D., 1Coltelli M.
1Istituto Nazionale di Geofisica e Vulcanologia - Osservatorio Etneo, Piazza Roma 2, 95123, Catania, Italy
High resolution shallow water multibeam data together with a set of scuba dives allowed to map and describe in detail the underwater extension of the Mt. Ilice lava flow. This lava flow represents the effusive product of one of the most important historical eruptions (1030 ± 40 AD, Tanguy et al., 2012) of Etna volcano. It extends on the eastern flank of the volcano for more than 10 km from Mt.
Ilice cinder cone, near Zafferana Etnea, to the coast between Pozzillo and Stazzo (Branca et al., 2011). Its front lies on both the coastal and offshore portions of the southernmost sector of the Chiancone volcanoclastic deposit.
The underwater portion of the lava flow extends for 150-250 m off the coast between Pozzillo and Stazzo showing a total width of about 1.5 km and a thickness ranging between 15 to 50 m, with maximum and minimum values in correspondence of the southernmost and central part, respectively. Its northern part is clearly cut for a total length of about 350 m by a N-S oriented fault scarp showing a dip slip movement. The maximum fault offset is 5 m, well detectable on the top of the lava flow between depths of 18 and 25 m bsl. This fault continues southward offsetting first the underwater extension of the Chiancone deposit with a nearly NNW-SSE direction and then the Acireale offshore, running for few km parallel to the coast at water depth between 300 to 350 m.
The northward extension of the fault is not marked by any clear morphological step both inland and offshore; however, a survey to identify its presence is still in progress.
Several scuba dives carried out along the fault trace allowed to: i) measure the vertical fault displacement (between 3 to 5 m); ii) recognize on the fault plane 1-3 m long and well defined vertical kinematic markers (slip lineation); iii) identify, locally, at the base of the fault scarp, the presence of one or two steps (between 50 to 70 cm high); iv) observe a less abundant cover of biological incrustations along the lowest part of the fault scarp (the lowest 1.5-2 m); v) detect, locally, along the base of the fault scarp, the presence of could freshwater releases.
The very young age of the lava flow allows us to interpret this structure as a very active fault;
moreover, its precise dating (1030 ± 40 AD) lets us to estimate a vertical displacement rate of 0.5 cm/y. This value is in agreement with the vertical displacement rate of about 0.42 cm/y inferred for the underwater extension of the S. Leonardello fault (one of the most important active faults of the Etna low eastern flank), which offset of some 10 m the Mt. Gorna lava flow (396 BC, Tanguy et al., 2012), located between Stazzo and S. Tecla villages. These values are in agreement with the vertical ground deformations (about 1.2 cm/y) recorded along this coastal sector in the last 15 years through InSAR data (Azzaro et al., 2013).
The total fault displacement represents more likely the sum of remarkable seismic events and aseismic creep phenomena occurring in the last 1 ka in the offshore and/or coastal areas near Pozzillo village. One of these seismic events could be the April 30, 1981 earthquake (intensity EMS=VI), which affected the area near Pozzillo (Azzaro, 1999; Azzaro et al., 2011). Macroseismic surveys (Patanè and Imposa, 1995) reported serious damages south of Pozzillo harbour, with NNW- SSE fractures showing vertical dislocations up to 13 cm; the epicentre was located offshore Pozzillo, where some fishermen observed water boiling and a small tsunami wave of 1 m. Another earthquake (intensity EMS=V-VI), producing damages in the Stazzo-Pozzillo area, was recorded on July 29 of the same year. Since several other earthquakes were felt during the last two centuries in the surroundings of Pozzillo, a study to better localize them will be carried out.
