Did lunar tides sustain the early Earth's dynamo?
Jérémie Vidal, David Cébron
Geological data show that, early in its history, the Earth had a large-scale magnetic field with an amplitude comparable to the one of the present geomagnetic field. However, its o…
On the Optimization of Singular Spectrum Analyses: A Pragmatic Approach
Fernando Lopes, Dominique Gibert, Vincent Courtillot +2
Singular Spectrum Analysis (SSA) occupies a prominent place in the real signal analysis toolkit alongside Fourier and Wavelet analysis. In addition to the two aforementioned analys…
Information theory, Signal Analysis and Inverse Problem
Dominique Gibert, Fernando Lopes, Vincent Courtillot +2
This book is intended for teaching Signal Analysis methods and Inverse Problems theory. It is completely open access and will remain free. It is currently illustrated with examples…
On the effect of the luni-solar gravitational attraction on trees
Jean-Louis Le Mouël, Dominique Gibert, Jean-Baptiste Boulé +5
In this paper, we revisit old electrical measurements conducted on a poplar tree in 2003 (Gibert et al. 2006), which showed the presence of a diurnal electrical signal, attributed…
On the external forcing of global eruptive activity in the past 300 years
J-L. Le Mouël, D. Gibert, V. Courtillot +11
The decryption of the temporal sequence of volcanic eruptions is a key step in better anticipating future events. Volcanic activity is the result of a complex interaction between i…
On the Nature and Origin of Atmospheric Annual and Semi-annual Oscillations
V. Courtillot, J-L. Le Mouël, F. Lopes +1
This paper proposes a joint analysis of variations of global sea-level pressure and of Earth's rotation (RP), expressed as the coordinates of the rotation pole and length of day. S…
On the annual and semi-annual components of variations in extent of Arctic and Antarctic sea-ice
F. Lopes, V. Courtillot, D. Gibert +1
The time series of northern hemisphere (NHSI) and southern hemisphere (SHSI) sea-ice extent are submitted to singular spectral analysis (SSA). The components are analyzed with Lapl…
On two formulations of polar motion and identification of its sources
F. Lopes, V. Courtillot, JL. Le Mouël +1
Differences in interpretation may arise from differences in formulation of the equations of celestial mechanics. This paper focuses on the Liouville system of differential equation…
A multi-decadal view of the heat and mass budget of a volcano in unrest: La Soufrière de Guadeloupe (French West Indies)
David E. Jessop, Séverine Moune, Roberto Moretti +11
Particularly in the presence of a hydrothermal system, many volcanoes output large quantities of heat through the transport of water from deep within the edifice to the surface. Th…
Dynamo action in sliding plates of anisotropic electrical conductivity
Thierry Alboussiere, Kamel Drif, Franck Plunian
With materials of anisotropic electrical conductivity, it is possible to generate a dynamo with a simple velocity field, of the type precluded by Cowling's theorems with isotropic…
Constraints on the composition and temperature of LLSVPs from seismic properties of lower mantle minerals
Kenny Vilella, Thomas Bodin, Charles-Edouard Boukaré +4
Here, we provide a reappraisal of potential LLSVPs compositions based on an improved mineralogical model including, for instance, the effects of alumina. We also systematically inv…
Fluid Dynamics of Earth's core: geodynamo, inner core dynamics, core formation
Renaud Deguen, Marine Lasbleis
This chapter is build from three 1.5 hours lectures given in Udine in april 2018 on various aspects of Earth's core dynamics. The chapter starts with a short historical note on the…
Small-Scale Metal/Silicate Equilibration During Core Formation: The Influence of Stretching Enhanced Diffusion on Mixing
Victor Lherm, Renaud Deguen
Geochemical data provide key information on the timing of accretion and on the prevailing physical conditions during core/mantle differentiation. However, their interpretation depe…
Revealing the cluster of slow transients behind a large slow slip event
William B Frank, Baptiste Rousset, Cécile Lasserre +1
Capable of reaching similar magnitudes to large megathrust earthquakes (), slow slip events play a major role in accommodating tectonic motion on plate boundaries. These sli…
Multiscale model of global inner-core anisotropy induced by hcp-alloy plasticity
A Lincot, Ph Cardin, R Deguen +1
Multiscale model of inner-core anisotropy produced by hcp alloy deformation 5 to 20% single-crystal elastic anisotropy and plastic deformation by pyramidal slip…
Earth's Inner Core dynamics induced by the Lorentz force
M. Lasbleis, R. Deguen, P. Cardin +1
Seismic studies indicate that the Earth's inner core has a complex structure and exhibits a strong elastic anisotropy with a cylindrical symmetry. Among the various models which ha…
Thermal convection in Earth's inner core with phase change at its boundary
Renaud Deguen, Thierry Alboussière, Philippe Cardin
Inner core translation, with solidification on one hemisphere and melting on the other, provides a promising basis for understanding the hemispherical dichotomy of the inner core,…
Melting-induced stratification above the Earth's inner core due to convective translation
Thierry Alboussiere, Renaud Deguen, Mickael Melzani
In addition to its global North-South anisotropy(1), there are two other enigmatic seismological observations related to the Earth's inner core: asymmetry between its eastern and w…
Zonal shear and super-rotation in a magnetized spherical Couette flow experiment
Daniel Brito, Thierry Alboussière, Philippe Cardin +6
We present measurements performed in a spherical shell filled with liquid sodium, where a 74 mm-radius inner sphere is rotated while a 210 mm-radius outer sphere is at rest. The in…
