High-Resolution Gravity Measurements on Board an Autonomous Underwater Vehicle: Data Reduction and Accuracy Assessment
Autor: Dinh Toan Vu, Jérôme Verdun, José Cali, Marcia Maia, Charles Poitou, Jérôme Ammann, Clément Roussel, Jean-François D’Eu, Marie-Édith Bouhier
Publikováno v: Remote Sensing, Vol 16, Iss 3, p 461 (2024)
Gravity on Earth is of great interest in geodesy, geophysics, and natural resource exploration. Ship-based gravimeters are a widely used instrument for the collection of surface gravity field data in marine regions. However, due to the considerable d

Development of a Lightweight Inertial Gravimeter for Use on Board an Autonomous Underwater Vehicle: Measurement Principle, System Design and Sea Trial Mission
Autor: Jérôme Verdun, Clément Roussel, José Cali, Marcia Maia, Jean-François D’Eu, Ossama Kharbou, Charles Poitou, Jérôme Ammann, Frédéric Durand, Marie-Édith Bouhier
Publikováno v: Remote Sensing, Vol 14, Iss 11, p 2513 (2022)
The purpose of this paper is to present the design, development and testing of an innovative instrument called GraviMob, which allows performing dynamic measurements of underwater gravity anomalies. After recalling the interest in underwater gravimet

Comparison of GNSS PPP-AR packages for post-processing seafloor geodetic data
Autor: Edgar Lenhof, Jean-Yves Royer, Valérie Ballu, Pierre Sakic, Charles Poitou, Mickael Beauverger, Thibault Coulombier, Denis Dausse, Gregor Jamieson, Pierre-Yves Morvan, Marc-André Gutscher
GNSS/A is a proven method to localize seafloor geodetic stations and, thus, to monitor seafloor tectonic phenomena. This approach combines GNSS positioning of a surface platform with acoustic ranging between this platform and acoustic beacons on the

Active Strike-Slip Fault Monitoring Using Marine Geodesy, Offshore Mt Etna, Sicily (Italy)
Autor: Jean-Yves Royer, Edgar Lenhof, Charles Poitou, Valerie Ballu, Thibault Coulombier, Denis Dausse, Pierre Sakic, Gregor Jamieson, Pierre-Yves Morvan, Marc-André Gutscher
In the framework of the European Research Council (ERC) funded project – FOCUS, testing laser reflectometry in a fiber optic cable to detect movement across an active submarine fault in real time, an array of eight acoustic beacons has been set up

Trace elements (TE) are indicative of industrial pollution in soils, but geochemical methods are difficult to implement in contaminated sites with large numbers of samples. Therefore, measurement of soil magnetic susceptibility (MS) has been used to
