Repeated bathymetric surveys as a fundamental tool to measure rapid seafloor variations in geologically-active areas: examples from Southern Italian coastlines

Daniele Casalbore

Abstract

Multibeam bathymetry has deeply changed our vision of the seafloor, allowing to map a large suite of landforms associated to oceanographic, sedimentary, volcanic and tectonic processes. Besides the advances in understanding the processes shaping the seafloor, these data represent a basic input both for a first assessment of marine geohazards and for planning more detailed studies. In this regard, the use of repeated bathymetric surveys in geologically-active areas is becoming a fundamental tool to evidence and monitor areas affected by rapid seafloor variations, whose genesis can be linked to active natural phenomena that otherwise would be often undetectable. In this paper, we show a review of examples from Southern Italy, where the application of such methodological approach allowed to monitor active erosive-depositional and volcanic processes.
