Can one use Earth's magnetic axial dipole field intensity to predict reversals?

Kyle Gwirtz, Matthias Morzfeld, Alexandre Fournier +1

We study predictions of reversals of Earth's axial magnetic dipole field that are based solely on the dipole's intensity. The prediction strategy is, roughly, that once the dipole…

A regime diagram for the slurry F-layer at the base of Earth's outer core

Jenny Wong, Christopher J. Davies, Christopher A. Jones

Seismic observations of a slowdown in P wave velocity at the base of Earth's outer core suggest the presence of a stably-stratified region known as the F-layer. This raises an impo…

Relating force balances and flow length scales in geodynamo simulations

Tobias Schwaiger, Thomas Gastine, Julien Aubert

In fluid dynamics, the scaling behaviour of flow length scales is commonly used to infer the governing force balance of a system. The key to a successful approach is to measure len…

Assessing the brittle crust thickness from strike-slip fault segments on Earth, Mars and Icy Moons

Frederic-Victor Donze, Yann Klinger, Viviana Bonilla-Sierra +3

Segment lengths along major strike-slip faults exhibit a size dependency related to the brittle crust thickness. These segments result in the formation of the localized 'P-shear' d…

Spatial and temporal development of incipient dunes

Cyril Gadal, Clément Narteau, Ryan C. Ewing +4

In zones of loose sand, wind-blown sand dunes emerge due the linear instability of a flat sedimentary bed. This instability has been studied in experiments and numerical models but…

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…

GipsyX/RTGx, A New Tool Set for Space Geodetic Operations and Research

Willy Bertiger, Yoaz Bar-Sever, Angie Dorsey +15

GipsyX/RTGx is the Jet Propulsion Laboratory's (JPL) next generation software package for positioning, navigation, timing, and Earth science using measurements from three geodetic…

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…

On-deck seismology: Lessons from InSight for future planetary seismology

Mark P. Panning, W. Tom Pike, Philippe Lognonné +12

Before deploying to the surface of Mars, the short-period (SP) seismometer of the InSight mission operated on deck for a total of 48 hours. This dataset can be used to understand h…

Distribution of interseismic coupling along the North and East Anatolian Faults inferred from InSAR and GPS data

Quentin Bletery, Olivier Cavalié, Jean-Mathieu Nocquet +1

The North Anatolian Fault (NAF) has produced numerous major earthquakes. After decades of quiescence, the 6.8 Elazığ earthquake (January 24, 2020) has recently reminded…
