This study reports the first accurate record of the Messinian Resedimented Gypsum in the forearc and back-arc basins connected to the Calabrian-Peloritan orogen. A multidisciplinary approach has been used to investigate a gypsum deposit located in the Benestare’s area (Calabria, Southern Italy). Such deposit is made of bedded gypsrudites displaying clastic selenite with chaotical textures. On the top, the gypsrudites are interspersed with gypsum lenses belonging to the branching-like facies. Despite these two facies seem different macroscopically, they show petrographic features, fluid inclusions, organic matter and Strontium isotopic values very similar to each other. On the other hand, both facies show fractured and folded crystals. Crystals are only locally corroded and preserve primary structure relict as well as allochthonous (organic debris) and autochthonous putative microbial remains. All crystals are rich in fluid inclusions but these are visibly affected by stretching and leaking (re-equilibration processes) suggesting a moderate plastic deformation during re-sedimentation and subsequent burial. Minimal transport of the deposit is testified by subangular shapes of the gypsum crystals. The gypsrudite and branching-like facies reveal an 87Sr/86Sr average value of 0.709045 and 0.709082, respectively. These values suggest a strong connection with the global Ocean and reduced freshwater input. The Benestare’s deposit originated from the partial to complete dismantling of selenite crystals related to the first stage (5.97–5.60 Ma) of the Messinian Salinity Crisis through gravitational collapse due to local controlling factors.

Abstract The quality of Southern Ocean sea ice simulations in a global ocean general circulation model (GCM) depends decisively on the simulated upper-ocean temperature. This is confirmed by assimilating satellite-derived sea ice concentration to constrain the upper-layer temperature of a sea ice–ocean GCM. The resolution of the model’s sea ice component is about 22 km and thus comparable to the pixel resolution of the satellite data. The ocean component is coarse resolution to afford long-term integrations for investigations of the deep-ocean equilibrium response. Besides improving the sea ice simulation considerably, the simulations with constrained upper-ocean temperature yield much more realistic global deep-ocean properties, in particular when combined with glacial freshwater input. Both outcomes are relatively insensitive to the passive-microwave algorithm used to retrieve the ice concentration being assimilated. The sensitivity of the long-term global deep-ocean properties and circulation to the possible freshwater input from ice shelves and to the parameterization of vertical mixing in the Southern Ocean is reevaluated under the new constraint.

The Temple of Athena is one of the main sacred areas of the Greek–Roman settlement of Poseidonia-Paestum (southern Italy). Several archaeological excavations were carried out here between the late nineteenth and early twentieth century. Unfortunately, the locations of these excavations are only approximately known, as are the geomorphology and stratigraphy of the temple area. A multidisciplinary study, including stratigraphic, geomorphological, archaeological, and sedimentological investigations, remote sensing, and electromagnetic and geoelectrical tests, was therefore carried out, shedding new light on the geomorphology and stratigraphy of the SW and W temple sectors. The geophysical data obtained revealed anomalies in the subsoil that probably correspond to ancient structures and the cutting of the travertine deposits around the temple. The position and extension of the trenches of the early archaeological excavations were also established.

AbstractArguably, the most famous myth told about Persephone is her abduction and marriage to Hades. The story clearly articulates the strong connection between marriage and death, and this episode became significant in both literature and religious practice in the wider classical Greek world. Reference to the story of Persephone’s abduction came to be used as a shorthand for evoking this connection, particularly in myth. This paper discusses two particular ways in which Persephone’s narrative was used in marriage and death. I examine the pre-marriage offerings to Persephone at Lokroi Epizephyrioi, in southern Italy, and the tradition of Athenian girls who died unmarried being buried as brides. These cultic instances frame a discussion of Brides of Hades, particularly in tragedy. Overall, I conclude that these girls do not attempt to replace Persephone, but rather to imitate her: they ‘play the role’ of Persephone at various stages of her own abduction and marriage story.

The effectiveness of the increase in passive ventilation was studied as remedial action for high concentrations of indoor radon gas activity. The rationale has been to apply the provisions of Directive 2013/59/EURATOM, partially implemented by a regional law of Puglia Region (Southern Italy). Residential buildings were selected based on characteristics common to those of commercial premises, which are the recipients of legislative obligations. The final goal of this study was to evaluate the feasibility of carrying out the same remediation activity for both types of buildings. From a previous survey in Puglia in 2013–2014, 18 houses were selected and passive ventilation strategy was applied in order to evaluate its effect on the radon activity concentration. A specially designed protocol defined frequency and time of windows operation. The average value of the annual measurement revealed a significant reduction of the internal radon activity concentration: mitigation ranged from 21 ± 5% to 58 ± 2% with an average value of 33 ± 3%. The results of the study showed that passive ventilation is an effective method of mitigation of the internal radon concentration if correctly designed according to the local characteristics of the buildings and habits of the occupants.
