An explanation is put forward for the instability observed within a precessing, rotating
spheroidal container. The constant vorticity solution for the flow suggested by Poincaré is …

The 75 year history of the American Geophysical Union has accompanied great advances in
our understanding of the physics and chemistry of the transition zone between the Earth's …

This paper reviews how the study of the surface gravity changes is able to provide useful
information on the Earth's structure and global dynamics. The spectral range which is …

In the analysis of surface gravity signals that may originate from the Earth's core, the step of
correcting for the atmospheric pressure fluctuations is one that must be done carefully. We …

A worldwide network of superconducting gravimeters (SGs) is presently running under the
coordination of the Global Geodynamics Project (GGP). SGs have proved in the past to be …

Gravimetry is a well-established tool to probe the deep Earth's processes. Geophysical
signals coming from the deep Earth, like the inner core free oscillations, have however never …

A harmonic development of the tide-generating potential (TGP), named RATGP95, has been
computed using an analytical method. The lunar part of the potential has been developed to …

There have been several investigations in the past for weak harmonic signals in the residual
spectrum of superconducting gravimeter (SG) data. Recently, a stack of four European SG …

The purpose of this paper is to model atmospheric pressure effects on surface gravity.
Pressure corrections are usually done with the help of an empirical trans fer function called …

We examine the possibility that the Earth's outer core, as a tidally distorted fluid-filled rotating
spheroid, may be the seat of an elliptical instability. The instability mechanism is described …
