Influence of grain size, shape and compaction on georadar waves: example of an Aeolian dune
Julien Guillemoteau, Maksim Bano, Jean-Rémi Dujardin
Many Ground Penetrating Radar (GPR) profiles acquired in dry aeolian environment have shown good reflectivity inside present-day dunes. We show that the origin of this reflectivity…
Regularization strategy for the layered inversion of airborne TEM data: application to VTEM data acquired over the basin of Franceville (Gabon)
Julien Guillemoteau, Pascal Sailhac, Mickael Behaegel
Airborne transient electromagnetic (TEM) is a cost-effective method to image the distribution of electrical conductivity in the ground. We consider layered earth inversion to inter…
On the Influence of the Data Sampling Interval on Computer-Derived K-Indices
Armelle Bernard, Menvielle Michel, Aude Chambodut
The K index was devised by Bartels et al. (1939) to provide an objective monitoring of irregular geomagnetic activity. The K index was then routinely used to monitor the magnetic a…
Excitation of the Slichter mode by collision with a meteoroid or pressure variations at the surface and core boundaries
S. Rosat, Y. Rogister
We use a normal-mode formalism to compute the response of a spherical, self-gravitating anelastic PREM-like Earth model to various excitation sources at the Slichter mode period. T…
