Abstract:
In this paper we update the Mediterranean fish inventory, analyse the biogeographic features of this fauna and provideexhaustive biodiversity data for the Ligurian and Tyrrhenian seas. According to the data available in 2010, the Mediterraneanfish diversity can be summarized as follows: 602 (including sub-species) bony fish species (Osteichthyes), 79 cartilaginous fishspecies (Chondrichthyes) and 3 cyclostomes (Agnatha); making a total of 684 species belonging to 173 families (147Osteichthyes, 24 Chondrichthyes, 2 Agnatha). Most species 403 (58.9%) have an Atlantic origin, 128 (18.7%) species arecosmopolitan, 90 (13.2%) species are Indo-Pacific, and 63 (9.2%) are endemic to the Mediterranean. In the Ligurian Sea,northern Tyrrhenian and southern Tyrrhenian Sea, the richness can be estimated at 454, 426 and 447 species, respectively. Themost speciose families for the Mediterranean as a whole, but also for the three intra-mediterranean areas studied are theGobiidae, Sparidae, Labridae and Blenniidae; whereas Carangidae is a numerically important family mainly at theMediterranean level. The percentage of endemic fishes within the intra-mediterranean areas studied gradually decrease acrosslatitude from the Ligurian Sea (9.4%) to the northern (8.7%) and southern (8.0%) Tyrrhenian Sea. The updated fish inventorycontains 81 Lessepsian and 48 Atlantic immigrant species, which represent 11.8% and 7.0% of the whole Mediterranean fishcommunity, respectively. The Ligurian Sea (3.1%) houses a higher amount of immigrants with respect to the northern (1.6%)and southern (2.7%) Tyrrhenian sectors.Field observations made during this study indicate that both the Ligurian and Tyrrhenian seas are presently subjected toincreasing colonization events by thermophilic species spreading from the southern Mediterranean and to a lesser degree by the arrival of exotic species either of Atlantic or Indo-Pacific origin.

Abstract:
Data on the biology and ecology of Galeus melastomus are old/absent for the Southern Tyrrhenian Sea, despite there being numerous studies in the wider area. A total of 127 specimens of G. melastomus from the southern Tyrrhenian Sea, collected in 2018–2019 using trawling nets, were analyzed to investigate size at sexual maturity, sex ratio, length–weight relationships, and feeding habits. To our best knowledge, this is the first time in which all these features were investigated in the Southern Tyrrhenian Sea for G. melastomus. The stomach content analysis showed that G. melastomus had intermediate feeding habits, preying on a great variety of species, especially Cephalopoda, Osteichthyes, and Crustacea. The Levin’s index value (Bi) was 0.53. Sex ratio was 0.92:1, with females slightly more abundant and bigger than males. The results also showed a decrease (33.7 cm for females, 31.1 cm for males) in length at 50% maturity (L50). This could be a result of anthropogenic stressors, such as overfishing and/or and environmental changes, which can induce physiological responses in several species. Our results highlighted the differences related to sexual maturity, growth, and feeding habits of the blackmouth catshark in the studied area, providing reference data to allow comparison with future studies on this species adaptations to this and other deep-sea areas in the Mediterranean Sea.

Abstract:
2015 - 2016
The topic of my PhD thesis is a seismic tomography which has as object of investigation Italy, particularly Southern Italy and Southern Tyrrhenian. This tomography has been obtained by means of inversion of teleseismic data. Seismic tomography is a method of investigation which is considerably stabilized in the field of Geophysics. Its goal is the achievement of a tridimensional velocity model of a subsoil of a determined area. For reaching this aim, it is necessary to gather arrival times of seismic events registered by seismic stations that are distributed in an opportune way on the area subject to process of investigation and an one-dimensional velocity model (that is, velocity only in function of depth). Through this last one, there is the computation of theoretical travel times for each pair seismic event – seismic station. This particular phase of method is called forward problem. Then, there is the computation of the difference between observed travel times and these theoretical travel times, a difference named residual. This is the description of so-called inverse problem. The computation happens in an iterative way and it stops when the residual is minimum. Obtained tridimensional velocity model corresponds with the model where residual is minimum. The entire process of operation of a seismic tomography is completely described in first chapter of this thesis. The second chapter describes the phenomen of subduction, that is of a particular process which happens, under determined conditions, at convergent boundaries of plates. I have dedicated a chapter to this phenomen because the area subject to this research, the basin of Southern Tyrrhenian, is a result of a roll-back subducting Ionian slab. After a paragraph dedicated to a general description of tectonic plates theory, other paragraphs describe the kinematics and the dynamics of subduction processes. This seismic tomography has been obtained by inversion of teleseismic travel times. This particular kind of choice has been made because teleseismic ray travel in upper mantle at high depths, so their inversion could supply us a good resolution of an area that we want to investigate until depth of 500-600 km. The third chapter of my PhD thesis is dedicated to teleseisms. In particular, there is a description of classification of seismic events according to their epicentral distance and how we can interpretate various seismic phases on a teleseismic seismogram. A paragraph is about the nomenclature of same seismic phases deriving from the reflection and the refraction of the waves on the discontinuity surfaces present in Earth's inner. The fourth and last chapter of my PhD thesis contains the results of research and their interpretation. First paragraph is dedicated to a brief summary of geological history of Southern Tyrrhenian. Second paragraph is dedicated to a description of software used for the research, that is FMTT (Fast Marching Teleseismic Transform), created by Nick Rawlinson in 2008. Third paragraph is dedicated to description of my data. I have utilised 1929 teleseisms (only P phases) recorded in period 1990-2012 by 122 southern Italian seismic station directly connected to ISC (International Seismological Centre). I have obtained several sections at various level of depth, from 25 km to 500 km and I have obtained several profiles NS and EW at fixed values of longitude from 14° to 16° and latitude, from 37° to 40° respectively. Results, compared with previous works in that area, confirm the presence of a subducting slab in Southern Tyrrhenian. Finally, my PhD thesis is enriched by various appendixes, which describe in a particular way mathematical techniques and geophysical definitions which I have used. [edited by author]
La mia tesi di Dottorato descrive una tomografia sismica dell'Italia, e in particolare di quella meridionale e del Basso Tirreno, ottenuta mediante l'inversione di dati telesismici. La tomografia sismica è oramai un metodo di indagine notevolmente consolidato nel campo della Geofisica e consiste nel ricavare un modello di velocità tridimensionale del sottosuolo di una determinata regione. Quest'ultimo si ottiene avendo a disposizione i tempi di arrivo di eventi sismici registrati da stazioni sismiche distribuite in maniera opportuna sull'area da indagare e un modello di velocità di partenza unidimensionale. Infatti, sfruttando quest'ultimo si calcolano per gli eventi sismici considerati dei tempi di arrivo teorici (questa fase prende il nome di PROBLEMA DIRETTO). Poi si calcola la differenza tra i tempi di arrivo realmente osservati e quelli teorici, che prende il nome di residuo (questa fase prende il nome di PROBLEMA INVERSO) e si procede in maniera iterativa in maniera che il residuo sia minimo. Il modello di velocità da ottenere è quello che corrisponde al residuo minimo. Il primo capitolo della tesi descrive la trattazione matematica della tomografia sismica, dopo un paragrafo introduttivo dedicato all'uso in generale dei metodi inversi in geofisica. La tomografia sismica si dice locale se gli eventi considerati sono locali. Si dice telesismica – come quella oggetto della mia tesi – se gli eventi considerati sono, lapalissianalmente, telesismi. Il secondo capitolo parla quindi dei telesismi, della loro definizione riguardo alla classificazione degli eventi sismici in base alla distanza epicentrale e delle fasi sismiche che si possono leggere da un sismogramma di un telesisma. Questo capitolo comprende un paragrafo sulla nomenclatura delle fasi sismiche e soprattutto quelle derivanti dalla riflessione e rifrazione delle onde su tutte le superfici di discontinuità presenti all'interno della Terra. E, a tal proposito, il terzo capitolo è un'introduzione alla struttura dell'interno della Terra con attenzione particolare che viene rivolta al fenomeno della subduzione. Questo perché uno slab di subduzione è presente all'interno del Basso Tirreno, zona “protagonista” della mia indagine tomografica. Il quarto capitolo è dedicato alla storia geologica del Basso Tirreno e alle evidenze delle precedenti indagini geofisiche che hanno visto questa area sotto la lente di ingrandimento. L'ultimo capitolo riguarda i risultati della mia indagine e la loro interpretazione. Ho utilizzato i tempi di arrivo di fasi P di 1929 telesismi (selezionati in base a un intervallo di magnitudo, a un minimo di stazioni registranti e all'intervallo di residuo di stazione) registrati nel periodo 1990-2012 da 122 stazioni dell'Italia centro-meridionale collegate all'ISC (International Seismological Centre). I risultati sembrerebbero, confrontati con quelli dei lavori precedenti, confermare la presenza di uno slab di subduzione nel Basso Tirreno. [a cura dell'autore]

Abstract:
The Southern Tyrrhenian subduction system shows a complex interaction among asthenospheric flow, subducting slab and overriding plate. To shed light on the deformations and mechanical properties of the slab and surrounding mantle, I investigated seismic anisotropy and attenuation properties through the subduction region. I used both teleseisms and slab earthquakes, analyzing shear-wave splitting on SKS and S phases, respectively. The fast polarization directions φ, and the delay time, δt, were retrieved using the method of Silver and Chan [1991. SKS and S φ reveal a complex anisotropy pattern across the subduction zone. SKS-rays sample primarily the sub-slab region showing rotation of fast directions following the curved shape of the slab and very strong anisotropy. S-rays sample mainly the slab, showing variable φ and a smaller δt. SKS and S splitting reveals a well developed toroidal flow at SW edge of the slab, while at its NE edge the pattern is not very clear. This suggests that the anisotropy is controlled by the slab rollback, responsible for about 100 km slab parallel φ in the sub-slab mantle. The slab is weakly anisotropic, suggesting the asthenosphere as main source of anisotropy. To investigate the physical properties of the slab and surrounding regions, I analyzed the seismic P and S wave attenuation. By inverting high-quality S-waves t* from slab earthquakes, 3D attenuation models down to 300 km were obtained. Attenuation results image the slab as low-attenuation body, but with heterogeneous QS and QP structure showing spot of high attenuation , between 100-200 km depth, which could be due dehydration associated to the slab metamorphism. A low QS anomaly is present in the mantle wedge beneath the Aeolian volcanic arc and could indicate mantle melting and slab dehydration.

Abstract:
The Pelagian Archipelago is located in a complex and wide geodynamic system characterized by the occurrence of two independent tectonic processes acting simultaneously: convergence along the Apennine-Maghrebian accretionary wedge and late Miocene-early Pliocene rifting in the Sicily Channel. Through high resolution seismic profiles acquired around the Lampedusa Island offshore, the reconstruction of an updated structural setting of this area and its regional correlation has been performed. The late Miocene-early Pliocene rifting affects directly the structural evolution of the Lampedusa plateau, with the development of a graben and half-graben setting in most of the offshore area, widely filled with the syn-rift deposits. In the northern sector, the activity of the normal faults associated with the rifting is active up to the early Pliocene, whereas it is quiescent since late Miocene in southern sector. This current fabric of the Lampedusa plateau derives by its involvement in regional extensional regime, lying in a dextral-transtensive zone and marked by pull-apart basins. In particular, two systems of the normal faults in the Lampedusa offshore have been recognized. The Master Extensional Faults oriented WNW-ESE represent the main structural alignment of the Lampedusa offshore and reflect the extensional trending of the Sicily Channel. The Second order of Extensional Faults, oriented NNW-SSE, bounds smaller pull-apart basins and are probably associated with the main dextral-transtensive regional regime. From the comparison with some preexisting models, an update stratigraphic-structural model is proposed also to the southeastern continental shelf between the Gela-Catania foredeep and the Hyblean foreland offshore, along the Marina di Ragusa offshore. The seismo-stratigraphic interpretation shows a NE-SW extensional faults system that involves only the late Miocene formations, probably connected to history of the Scicli Line. Furthermore, the late Miocene extensional tectonic activity involves widely affects the offshore portions of the Hyblean foreland and its ramp, but it does not show evidences that this activity has involved the Plio-Pleistocene succession. The deposition of the Gessoso-Solfifera Formation has been widely recognized in the Hyblean foreland ramp, demonstrating that the evaporitic deposition does not is a peculiarity only of the deposits within the semi-isolated and marginal sub-basins or of the thrust top mini-basins of the Appennine-Maghrebides belt, but extends also in areas where the extensional tectonic have been dominant. Through Multibeam bathymetric data, an update characterization of the geomorphological setting of the north-east Sicily continental shelf, between Milazzo Promontory and the area offshore from the Saponara River, is provided. Furthermore, through high-resolution CHIRP seismic profiles interpretation, a reconstruction of the evolution of the last eustatic sea level cycle is performed. The lowstand succession, corresponding with the foreset of the prograding clinoforms of the continental margin deposits, determines the accommodation space for the depositional processes that occur during the rise of the sea level. In fact, the evolution of the transgressive and highstand wedges is strongly influenced by the geometry of the underlying lowstand succession. The transgressive wedge is developed in the 80-100 m bathymetric range and consists of the relict geomorphic elements that represent past landscape. These elements tracked the variations in coastline position during the last sea-level rise, formed during an interval of relatively reduced rate of sealevel rise. Furthermore, a reconstruction of the geomorphological evolution of the past coastal systems during the last transgressive stage is provided. The highstand wedge consists of the Corriolo, Muto, Niceto, Cocuzzaro and Rometta delta deposits that widely develop on the offshore portions of the inner continental shelf.

Abstract:
Up to now there are not detailed studies about the structures and the kinematic related to the Plio-Pleistocene tectonics in southern Sardinia, although tectonic activity during the latest million years is long since known in the Island. Then, the general aim of this research is to improve the understanding of the recent geological evolution of the southern Sardinian block, trying to calculate the extension affecting the crust, to reconstruct the paleostress fields and to define a model of the tectonic evolution of the southern Sardinia during this period, considering the new data obtained from this research and the data available from literature on the geodynamic evolution of the western Mediterranean, in particular about the opening of the Tyrrhenian Sea. To achieve this purposes, the research focuses on the study of the most important structure related to the Plio-Pleistocene tectonics: the "so-called" Campidano graben. This structure has been studied mainly interpreting the seismic lines acquired in the Campidano plain by SAIS in the early sixties and by the joint venture AGIP-Progemisa S.p.A. in the early nineties that have been made available for this research by the Regione Autonoma della Sardegna and Progemisa S.p.A. The continuation of the Campidano in the Cagliari Gulf has been studied interpreting the ministerial seismic lines aquired by AGIP in the seventies in the offshore of Cagliari. The main results achieved from the research are: - the 3D model of the Middle Pliocene erosional surface at the base of the Samassi formation detected in the subsurface of the Campidano plain; - the extension values and the deformation rates affecting the Campidano area during Plio-Quaternary times; - the reconstruction of the paleostress field active during Pliocene time in the Campidano graben; - a comparison between the structural setting of the Campidano and the structural setting of the southeastern Sardinian margin; - the integration of the data achieved during this research with the data available from literature on the geodynamic evolution of the western Mediterranean, in particular about the opening of the Tyrrhenian Sea. The 3D model of the Middle Pliocene erosional surface has been built using the two-way time structural maps of this surface carried out in both the northern and southern Campidano. This surface shows a gently rolling landscape, typical of the erosion and planation surface developed in continental environments, both in the subsurface of the southern and northern Campidano plain. In the Campidano of Oristano, the maximum depth of the bottom of the Samassi formation is approximately -1100 m, while in the southern it is roughly -900 m (mean velocity assigned 2 km/s). The two-way time structural maps show that both the northern and the southern Campidano graben are bounded in the western edges by master faults dipping to the east, but differences arise in the trends of the faults: mostly N-S in the northern Campidano and NW-SE in the southern Campidano. N-S normal faults affected the whole Samassi formation and the within-plate basalts that post-date it, so we may admit that an important extension occurred after its deposition, that is in Pleistocene time. The structures from seismic interpretation, that characterized the Plio-Quaternary evolution of the so-called Campidano graben have been validated during the drafting of the two-way time maps and with the structural and stratigraphic data available on surface. This allowed to construct a validated 3D model from which achieved the most possible reliable values of extension and paleostress. To quantify the Plio-Quaternary deformation in southern Sardinia the 3D model of the Middle-Pliocene erosional surface (roughly 3.5 Ma in age) has been considered. The extension has been calculated restoring the cross-sections achieved from the 3D model. In the southern Campidano, extension values range from 205 m to 596 m and the percentage of extension from 1.65% to 5.72%. In the northern Campidano extension values range from 171 m to 465 m and percentage of extension from 0.84% to 2.50%. Although the Plio-Pleistocene time-markers (3.5 Ma the erosional surface at the base of the Samassi formation and 2.5 Ma the surface sealed by the basalt lava flows in northern Campidano and a reflector calibrated with the Campidano1 well in the southern Campidano) are not very well constrained, they allow to estimate the vertical slip rate (0,6 mm/yr) and the extension rate (0,3 mm/yr in the northern Campidano and 0,4 mm/yr in the southern Campidano). Considering the erosional surface sealed by the basalt-lava flows of the "giare" to the east of Campidano that occurs up to 550 m above the sea level and the age of 3.0 Ma of the basalts that seal it, an uplift rate of 0.18 mm/yr can be calculated if a marine origin for this surface is confirmed. Furthermore, the difference in elevation between the higher basalts that crop out in the central Sardinia (approximately 700 m in the Orroli basalt plateau) and those detected in the subsurface (-440 m in the northern Campidano) is related to tectonic activity that is at least Pleistocene in age. Therefore, during the whole Plio-Quaternary tectonics, considering the Middle Pliocene erosional surface at the base of the Samassi formation detected at -1100 m in the northern Campidano, vertical displacements on the order of 1800 m can be inferred. The paleostress field active during Pliocene time in the Campidano area has been reconstructed using the movement vector on the fault plane achieved from the restoration of the Middle Pliocene erosional surface in both the northern and southern Campidano using two different methods that showed almost the same results. In the northern Campidano, an extension oriented roughly E-W, with the principal stress axes: σ1=263/77; σ2=356/1; σ3=86/13; has be inferred. In the southern Campidano, the extension is oriented roughly ENE-WSW, with the principal stress axes: σ1=105/85; σ2=332/3; σ3=242/3. The evolution during Pliocene in the southern Sardinia seems to be strictly related with the evolution of the sector of the southern Tyrrhenian basin located roughly south of the 40° parallel. This can be infer from the similarities in ages and stuctures in the eastern Sardinian margin and Campidano area. It seems that the extensional tectonics started in the Upper Miocene in the Sardinian Basin and Cornaglia Terrace and migrated westward in Sardinia and eastward in the Vavilov Basin. Concerning the Pliocene tectonics affecting Sardinia, therefore, it seems to be directly related to the beginning of the extension in the Tyrrhenian Basin, due to the eastward roll back of the subducting Adriatic plate. It seems, instead, that the Pleistocene tectonics recognized in Sardinia can not be related directly with the evolution in the Tyrrhenian Basin, because, although extensional tectonics continued in the Marsili Basin until now, no active tectonics occurs in the Sardinian Basin and Cornaglia Terrace. Thus, the recent uplift affecting the southern Sardinia is most likely related to the lithospheric structure inherited from the pre-Pliocene geodynamic evolution of the western Mediterranean, during which the lowering of the density in the mantle lithosphere could be caused an uplift up to 1620 m, if a normal thick mantle lithosphere (90 km) is considering as start point, or up to 720 m, considering the present day thinned mantle lithosphere (40 km), or by the thinning of the mantle lithosphere connected with process of intensive convective heating (thermal thinning).

The main goal of this research focuses on the provenance, compositional and textural investigation of modern sand supplied from volcanic terrains (southern Tyrrhenian sea). This is a contribution to quantify the controls on volcaniclastic sand composition among volcanic areas with different tectonic settings and compositions. Specifically, an important aim of this research is to quantitatively compare the relation between areal distribution, texture and composition of “source” lithotypes – which are the clastic debris producer – with respect to texture and composition of "volcano-derived" sediments. The study area covers the coastal perimeter/stretch of two Italian volcanic provinces in the southern Tyrrhenian sea: Aeolian islands and Campania province. Particular attention has been given to the factors that control the relationships between grain rounding, grain-size, sand composition, texture and source rocks. This research provide a good opportunity to define the provenance signatures of detritus eroded from lavas with different compositions, pyroclastic and minor sedimentary rocks. Different sandy petrofacies for the studied areas of Campania province have been formalized. In order to investigate on provenance, pre-burial processes, composition and texture of modern sand supplied from volcanic terrains, different studies have been carried out through:  Sieving analyses;  Polarizing microscope and Electron Microprobe;  Image analysis (roundness study);  Geographic Information System analysis (SGI calculation). There is a clear differences between Aeolian Islands costal beach sand and Campania coastal beach sand in terms of detritus maturity. Grain-size distribution within Aeolian beach sediment show a tendency towards coarser sand fraction to gravel, whereas Campania coastal samples show a tendency towards medium to fine sand fractions; this indicates a varied physical disintegration of the source rocks. The major components of Aeolian islands and Campania beach sands are monomineralic grains, sedimentary and volcanic lithic fragments with lesser amounts of calcareous bioclasts. Samples from Aeolian islands and Portici Sorrento coastal stretch have an high percentage of volcanic lithic fragments (Lvl > Lvmi> Lvv), whereas samples from Pozzuoli, display an average percentage among Lvl~Lvmi~Lvv. Three different petrofacies have been defined along Campania coastal stretch: sedimentary (Apennines), Vesuvian and Phlegrean fields petrofacies. Stromboli, Vulcano, Alicudi and Filicudi sands have a dual basaltic/shoshonitic and andesitic composition “signatures”. Panarea, Lipari and Salina sands have a wider range of composition “signatures” ranging from basalts to rhyolites. there is evidence that, on Aeolian islands, sand composition does accurately reflect bedrock composition except in the case of source areas dominated by pumice outcrops (e.g. Lipari islands), whereas in more protected and quite beach-environment such as Pozzuoli bay, this grain types (pumice, associated to more evolved [acid] volcanism and then explosive volcanism) have been found and resulted to be texturally more preserved. In the sandy detritus the persistence for the lithic grains is ranked as follows: Lvlblg, Lvmiblgl, Lvvblgl > Lvlbrgl, Lvmibrlgl, Lvvbrgl > Lvlclgl, Lvmiclgl, Lvvclgl > Lvf > Lvlgrgl, Lvmigrgl, Lvvgrgl, pumice. Thus, mafic source rocks will be overestimated and more acid source rocks will be underestimated in the stratigraphic record. New volcanic lithic compounds have been introduced (Lvlgrgl, Lvmigrgl, Lvvgrgl) then who will study the ancient stratigraphic records will know that the Lvlgrgl means dacitic provenance. New discriminating diagrams have been introduced which allow to obtain important information among the volcanic source rocks ranging from basic to acid composition. Lvlblgl, Lvmiblgl, Lvvblgl (1); Lvlbrgl, Lvmibrgl, Lvvbrgl (2); Lvlgrgl, Lvmigrgl, Lvvgrgl (3) can be produced not only by basaltic, andesitic and dacitic source rocks but also by source rocks with the same SiO2 content belonging at different alkaline series (e.g. trachybasalt, shoshonite, latite, trachyandesite, trachydacite, trachyte). Campania samples displaying an higher roundness degree which decrease towards Phlegrean Fields area from north (Volturno river mouth) to south and, show an higher percentage of (3), (4), (5) and (6) roundness category, whereas Aeolian islands samples have an higher percentage of (1) and (2) roundness category. There is a correlation between roundness and geographic location of the Aeolian islands beaches. Sand grains round more efficiently under gentler wave action of the eastern side whereas the more angular grains of the north-western beaches are immediately eroded from the nearby cliffs with null or quite minimal reworking. A new methodological and research approach for roundness degree calculation have been tested by conducting image analysis. By relating GIS, compositional and textural results, it is possible to affirm that lavas source rocks have an higher propensity to create sandy detritus than pyroclastic source rocks. This finding has implications for the stratigraphic record especially for the sandy pumice clasts which could be underrepresented in older volcaniclastic deposits and overrepresented in other detritus size fractions. This actualistic study helps in understanding factors controlling siliciclastic sediment composition and texture, in turn, will help in deciphering major controls on ancient volcaniclastic successions, especially those where volcanic terrains have been totally lost by erosion

Abstract:
This monograph presents a significant portion of the scientific results of the archaeological excavations at the Bronze Age settlement site of Punta di Zambrone on the Tyrrhenian coast of Calabria (southern Italy). These excavations were conducted from 2011 to 2013 in an Italian-Austrian cooperation. The book is the first in a series dedicated to the final publication of those excavations and focuses on the later part of the settlement history (13th–12th cent. BCE). Major topics include the topography of the site (including a harbour bay), its chronology, investigations into the economic basis of the Bronze Age society and its local, regional and interregional interactions. The new data from Punta di Zambrone are evaluated in comparison with new research results from coeval sites in Italy and Greece, which forms the basis for a historical contextualization of the settlement and thus contributes to the broader reconstruction of Mediterranean history at the end of the second millennium BCE. These coeval sites are presented by their excavators or investigators. The authors conducted geophysical and bathymetric surveys as well as underwater archaeological investigations, typological analyses of artefacts, a definition of the relative and absolute chronology, archaeobotanic and archaeozoological studies, aDNA analysis, Sr isotope analyses on human and animal teeth, chemical and Pb isotope analyses on metal artefacts, provenance analyses of pottery vessels, amber and stone artefacts (from Zambrone and other sites).

Abstract:
Starting from the definition of the Goda spread parameter γ50 and from the verification of the spatial homogeneity hypothesis, the 50-year significant wave height H50 was obtained for a sea area characterized by a limited wave observation period. The procedure was applied for the location of Cetraro in the Southern Tyrrhenian Sea starting from the waves recorded offshore Ponza, provided that the spatial homogeneity hypothesis was verified. This hypothesis was not verified, however, between the wave measurement stations of Crotone or Catania and two wave measurement stations recently installed by Calabria Region in the Ionian Sea. In the Southern Tyrrhenian Sea the results of H50 were compared with the ones obtained with the method of fetch transposition of De Girolamo & Contini (1998).
