Low-cost remotely operated underwater and unmanned aerial vehicles: New technologies for archaeo-geophysics
2017
In this paper we present a device for magnetic survey devoted in particular for archaeological purposes. The device is able to perform accurate measurements of the total magnetic field, it is a flexible device, programmable by the users to be suitable for any specific need. The device relies upon microcontroller, a digital three axes Fluxgate magnetometer, a GPS, and a Real Time Clock (RTC) module. The device is compact and lightweight to be assembled on aerial and marine drones. Recently, Remotely Operated Vehicles (ROV) and Unmanned Aerial Vehicles (UAV) gained great potential for archaeo-geophysics because of their versatility and low cost, therefore the magnetometer represents a very us…
Advances in microgeophysics for engineering and cultural heritage
2009
A large number of unconventional investigations have been implemented, tested, and validated in the field of microgeophysics, with the aim being to solve specific diagnostic and/or monitoring problems regarding civil engineering and cultural heritage studies. The investigations were carried out using different tomographic 2D and 3D approaches as well as different energy sources, namely sonic, ultrasonic and electromagnetic (radar) waves, electric potential fields, and infrared thermography. Many efforts have been made to modify instruments and procedures in order to improve the resolution of the surveys as well as to greatly reduce the time of the measurements without any loss of informatio…

A regional-scale discontinuity in western Sicily revealed by a multidisciplinary approach: A new piece for understanding the geodynamic puzzle of the…
2015
The results of an integrated stratigraphic, structural, geophysical, and geochemical study reveal the presence of a crustal discontinuity in western Sicily that, at present, runs roughly N-S along a band from San Vito Lo Capo to Sciacca. The boundary between the two zones of this discontinuity is nearly orthogonal to the main thrust propagation of the Sicilian thrust-and-fold belt. The different Permian to Tertiary sedimentary evolution recorded by the two zones appears related to this discontinuity, with thick carbonate platforms in the western sector facing deepwater successions in the eastern one. The presence of Upper Triassic reefs, huge megabreccia bodies, and widespread submarine vol…
