“…Terrigenous turbidite deposition was enhanced in both sub‐basins during Messinian time by the exposure of the pre‐Messinian shelf (Figure c) and by the accelerated erosion of the surrounding belts. To the NE, the Venetian–Friulian Basin is subaerially exposed during the maximum Messinian sea‐level drop, a result that agrees with the proposed fluvial origin of the incised valleys and dendritic drainage network in the present‐day onshore and offshore subsurface (Donda et al., ; Ghielmi et al., , ; Toscani et al., ; Zecchin et al., ) (Figure b). Further to the east, a vast portion of the Mesozoic Istrian‐Dalmatian platform, located in present‐day Croatia region (Figure a) and the Adriatic Sea, were subaerially exposed, which is also in agreement with previous works (Velić, Malvić, Cvetković, & Velić, ) (Figures a and a).…”

“…Although the timing of closure and reopening of the southern Adriatic sill during the late Messinian is beyond the purpose of this work, the presence of marine bioevents (e.g., the first occurrence of Turborotalita multiloba and the Neogloboquadrina acostanesis sx/dx coiling change) in the pre-MSC sequences (Blanc-Valleron et al, 2002; Ghielmi et al, 2010, 2013and Rossi, 2017. The pre-evaporitic shoreline break is highlighted in the northeast.…”

“…Late Messinian incised valleys in the Venetian–Friulian Basin onshore and offshore (Donda et al., ; Toscani et al., ; Zecchin, Donda, & Forlin, ) led to suggest a maximum relative sea‐level drop in the Northern Adriatic region of more than 100–200 m during MSC acme, but not exceeding 900 m (Ghielmi et al., ). This is in divergence with previous interpretations from Roveri, Flecker, et al.…”

“…Tectonic shortening affected the PPNA at different times and with variable directions during the Cenozoic (e.g., Toscani et al, 2016). Since the middle-late Miocene, the thrust front of the Northern Apennine thrust-fold-belt bounds to the southwest the Po Plain and Northern Adriatic Foredeep Basins (Fantoni & Franciosi, 2010; Ghielmi al., 2013;Rossi et al, 2015). The Western and Southern Alps bound the Western Po Plain foredeep basins to the north, while the PPNA is connected to the northeast to the Venetian-Friulian Basin (Figure 1a).…”

“…To this aim, we analyse public and private (courtesy of Eni Upstream) subsurface data and carry out a 3D reconstruction of the subaerial and submarine landscape of the Po Pain and Adriatic foreland during the MSC desiccation peak, that is, after the MSC stage 1 according to the chronostratigraphy by Roveri, Flecker, et al (2014), , Roveri et al (2016). We take advantage from high-resolution stratigraphic data (e.g., sedimentological, palaeontological, and geochemical data) and detailed geological constraints (e.g., seismic-based and well logs) for the study region also provided by recent works (Ghielmi, Minervini, Nini, Rogledi, & Rossi, 2010, 2013Rossi, 2017;Rossi, Minervini, & Ghielmi, 2018;Rossi, Minervini, Ghielmi, & Rogledi, 2015). We are able to (a) provide the palaeotopography of the PPNA, which improves our understanding of the basin evolution and its relationships with the broader Mediterranean palaeogeography during the MSC, and (b) recognize V-shaped valleys filled with Messinian post-evaporitic and Pliocene deposits in the seismic data along the Southern Alps, which imply a syn-MSC or older age of the presentday southern Alpine river drainage pattern.…”

Restored topography of the Po Plain‐Northern Adriatic region during the Messinian base‐level drop—Implications for the physiography and compartmentalization of the palaeo‐Mediterranean basin

et al. 2018

The Messinian Salinity Crisis (MSC) involved the progressive isolation of the Mediterranean Sea from the Atlantic between 5.97 and 5.33 Ma, and a sea‐level fall whose timing, modalities, and magnitude remain actively debated. At that time, the central Mediterranean was undergoing strong tectonic activity due to the rollback of the Adria slab and eastward migration of the Apenninic belt. The combined effects of the post‐evaporitic MSC sea‐level drop and morphostructural changes (due to the Intra‐Messinian phase) resulted in a regional unconformity, which shows erosive markers and conformable relationships with the Messinian and Mio–Pliocene boundary in the Po Plain and Northern Adriatic Foreland. Here, we produce a palaeotopographic reconstruction of the Po Plain‐Northern Adriatic region (PPNA) during the Messinian peak desiccation event based on such regional unconformity. We mapped this surface through wells and 2D seismic data form Eni's private dataset. The unconformity shows V‐shaped incisions matching the present‐day southern Alpine valleys and filled with Messinian post‐evaporitic and Pliocene deposits, suggesting that the modern drainage network is at least of late Messinian age. The Messinian unconformity has been restored to its original state through flexural‐backstripping numerical modelling. The resulting landscape suggests a maximum sea‐level drop of 800–900 m during the MSC peak, and is consistent with stratigraphic and sedimentologic data provided by previous works. The modelled shoreline separates the subaerially eroded land from an elongated basin composed by two ca. 400 and 1,000 m deep depocentres during the maximum sea‐level drop. These results suggest that the Mediterranean was split in at least three sub‐basins subject to independent base levels, fresh‐water budgets, and flexural responses during the maximum lowstand.

This paper presents the results of the interpretation of a set of high‐resolution seismic lines integrated with multibeam echosounder data acquired in a coastal area in the Northern Adriatic Sea. The aim of the study was to reconstruct the stratigraphic evolution of a late Quaternary sedimentary succession offshore the town of Bibione, North‐Eastern Italy, by recognising the key unconformities, identifying the main depositional units, dating them and reconstructing the depositional environments in relation to relative sea‐level variations. Specifically, four sedimentary units, separated by erosional unconformities associated with the development of deep channels, were identified and dated based on literature information. By interpreting the seismic data, sedimentary dynamics were reconstructed and palaeoenvironments identified. The lower unit corresponds to a paludal environment, showing abundant gas seeps and accumulations (bright spots); the two intermediate units correspond to fluvial deposits, filling the deep incisions that characterise the bounding surfaces. Finally, the shallowest unit, bounded by a wave‐ravinement surface incised by tidal currents, corresponds to the Holocenic progradation of the coastal wedge. In addition, several vertical gas chimneys were identified, ranging in width from a few metres to 20–30 m. These were present in all units, often reaching the sea floor. Finally, elongated mounds, about 300 m wide, at the sea floor were recognised. The bathymetric and seismic characteristics of these elongated bodies and their relationship to adjacent sedimentary bodies suggest that they are probably methane‐derived carbonate formations known as ‘Trezze’ or ‘Tegnùe’. These names recall the fact that the trawls of the local fishermen were often hindered (‘tegnù’ in the Venetian language) or even cut off by these formations.

A B S T R A C TThe Port of Trieste is an international hub for land and sea trade with the dynamic markets of central and eastern Europe. Thanks to its deep natural draft (about 18 m), the modern high-capacity vessels can moor to the piers. In view of the foreseen increase in maritime traffic, this harbour is undergoing modernization in order to improve the commercial traffic capability. In this expansion plan, the container Trieste Marine Terminal, Pier VII, is seeking an extension by about 200 m. In support of this feasibility study, multidisciplinary data acquisition was conducted in order to characterize the seabed, the sub-bottom sediments and the bedrock (flysch formation) in front of the Trieste Marine Terminal. The acquisition of high-resolution swath bathymetry, side-scan sonar and magnetometer data allowed a detailed analysis of the seabed conditions from an environmental and safety perspective. High-resolution seismic reflection data enabled us to characterize the Plio-Quaternary soft sediments and the underlying bedrock. A static underwater refraction survey was performed using hydrophone array deployed on the sea bottom to obtain seismic velocities and to achieve a reliable time-to-depth conversion of reflection seismic data by first-arrival tomographic inversion. In addition to geophysical investigations, 11 offshore boreholes were drilled for detailed logging. In situ standard penetration tests were performed on core samples with the use of a pocket penetrometer and pocket vane in order to obtain uniaxial compressive strength, undrained shear strength and undrained cohesion values, and assess the cohesive soils. During drilling, 17 undisturbed samples and 12 semi-disturbed samples were extracted to perform laboratory tests for the identification of the principal geotechnical parameters. The goal was to obtain a reliable geological/geotechnical model in front of the Trieste Marine Terminal -from the seabed to the bedrock. Below the seafloor, a sequence of about 20-30 m thickness, containing Plio-Quaternary soft sediments, overlies the flysch, which locally presents alteration with rocks of reduced quality. The geophysicalgeotechnical integrated approach allowed us to identify and map the top of the bedrock and provided valuable information for planning the pier extension project.
