The Mediterranean Basin is characterized by a significant variability in tectonic behaviour, ranging from subsidence to uplifting. However, those coastal areas considered be tectonically stable show landforms at elevations consistent with eustatic and isostatic sea level change models. In particular, geomorphological indicators—such as tidal notches or shore platforms—are often used define the stability of coasts. We present results swim surveys nine rocky sectors central Sea using Geoswim...

The inventory and categorization of an extensive coastal boulder assemblage originating from storm wave transport on the coastline Fenoliga Island (Northern Adriatic Sea, southern Istria, Croatia) are presented discussed herein. study adopted use a commercial Uncrewed Aerial Vehicle (UAV) Structure Motion-MultiView Stereo (SfM-MVS) photogrammetry for construction 3D model island. A Digital Elevation Model (DEM) orthomosaic were produced employed mapping in GIS. In total, 592 boulders...

The photogrammetric method is widely used in coastal areas and submerged environments. Time-lapse images collected with unmanned aerial vehicles are to reproduce the emerged areas, while taken by divers ones. Conversely, 3D models of natural or human-made objects lying at water level severely affected difference refractive index between air seawater. For this reason, matching emergent coasts has been very rarely tested never Earth Sciences. availability a large number time-lapse images,...

Tidal notches, long regarded as reliable indicators of mean sea level, have been extensively studied along carbonate coasts in the central Mediterranean Sea. Previous studies revealed a correlation between genesis tidal notches and range, lithology, cliff foot depth wave energy. In 2020 Geoswim campaign at Lampedusa, southernmost island Pelagie archipelago (Italy), 'anomalous' were identified. Unlike normal observed elsewhere, those Lampedusa's southern bays exhibited particular behavior...

This study presents a world review as well new additional data in form of submerged speleothems that are used for paleo sea level reconstructions. Speleothems significantly contributed to the understanding global and regional variations during Middle Late Quaternary. The studied cover last 1.4 Myr focused mainly on Marine Isotope Stages (MIS) 1, 2, 3, 5.1, 5.3, 5.5, 7.1, 7.2, 7.3 7.5. Results reveal represent extraordinary archives providing detailed information former changes. We present...

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 Mediterranean Sea. Coastal cave deposits significantly contributed understanding regional sea-level variations during Middle Late Quaternary. The studied cover last 1.4 Myr focused mainly on Marine Isotope Stages (MIS) 1, 2, 3, 5.1, 5.3, 5.5, 7.1, 7.2, 7.3 7.5. indicate that represent extraordinary archives can provide detailed...

<p>Storms and storm surges could increase their impact on rocky coasts in the next years due to global warming. In recent years, study of boulders moved by waves seems have played an important role. A key indicator that can follow extreme events shores includes coastal detached from bedrock. These deposits became focus a several studies since play significant role hazard assessment. First regarded boulder related tsunami events, but recently many sites with large clasts been...

<p>The Mediterranean basin displays a variety of neotectonics scenarios leading to positive or negative vertical displacement, which change the position former coastlines. As result, best locations evaluate sea levels and validate sea-level models are tectonically stable areas. There number coastal areas considered be based on elevation paleo markers, absence historical seismicity, by their far from major faults. We report here results swim surveys carried out at such following...
