Description
Session chaired by I. Kolmasova and B. Canuel
Transmission muography is a rising technique in domains such as geophysics and civil engineering. It provides dynamic information about the density distribution around the detector thanks to the attenuation of a natural, passive source: cosmic muons. This long-reach technology provides complementary information to classical prospecting tools for the study of active, heterogenous...
Geophysical measurements using highly sensitive Superconductive Quantum Interference Device (SQUID) sensors have been in use since more than two decades. Owing to their extreme sensitivity, SQUIDs require very low noise environment for stable operation. The requirement of unshielded environment for geophysical data acquisition further pushes the need to find ways to reduce unwanted cultural...
Evapotranspiration (ET) is a major term of the water cycle which remains one of the biggest sources of uncertainty in hydrology. It is necessary to better understand this component and to develop new approaches to improve its quantification. Gravimetry is a geophysical method that measures variations in the Earth's gravity field “g”. Superconducting gravimeters (SG) provide continuous and...
Sequences of bipolar pulses, which are believed to identify the initiation of the majority of both cloud-to-ground (CG) and intracloud lightning flashes in electromagnetic recordings, have been regularly detected by magnetic loop antennas installed at the external site of LSBB at Vestale on the Plateau d’Albion. Since 2013, numerous studies on lightning initiation based on the LSBB data...
The work proposed in this presentation is part of a global project dealing
with the characterisation of heterogeneous media by both electromagnetic and
mechanical full waveform inversion. Indeed Full Waveform Inversion (FWI) of
seismic reflection (SR) or Ground Penetrating Radar (GPR) data is an efficient
approach to reconstruct subsurface physical parameters with high resolution.
We...
