Geophysical Research Letters, 2023 Climate model estimates show significant groundwater depletion during the 20th century, consistent with global mean sea level (GMSL) budget analysis. However, prior to the Argo float era, in the early 2000’s, there is little information about steric sea ...

Remote Sensing, 2022 Due to the conservation of global angular momentum, polar motion (PM) is dominated by global mass redistributions and relative motions in the atmosphere, oceans and land water at seasonal time scales.

Hydrological Excitation of Polar Motion Derived from GRACE Gravity Field Solutions
International Journal of Geophysics, 2011 The influence of the continental water storage on the polar motion is not well known. Different models have been developed to evaluate these effects and compared to geodetic observations.

Journal of Astronomy and Space SciencesTwo main components of polar motion are Chandler wobble and annual wobble. Annual wobble is obviously caused by the seasonal perturbations on the Earth – such was suspected as well as readily confirmed in unison.

Reducing filter effects in GRACE-derived polar motion excitations
Earth, Planets and Space, 2019 Polar motion is caused by mass redistribution and motion within the Earth system. The GRACE (Gravity Recovery and Climate Experiment) satellite mission observed variations of the Earth’s gravity field which are caused by mass redistribution.

Phonon-enhanced nonlinearities in hexagonal boron nitride
Nature Communications, 2023 Polar crystals can be driven into collective oscillations by optical fields tuned to precise resonance frequencies. As the amplitude of the excited phonon modes increases, novel processes scaling non-linearly with the applied fields begin to contribute ...

Elliptic polarisation of the polar motion excitation
Journal of Geodesy, 2015 Because of its geophysical interpretation, Earth’s polar motion excitation is generally decomposed into prograde (counter-clockwise) and retrograde (clockwise) circular terms at fixed frequency. Yet, these later are commonly considered as specific to the frequency and to the underlying geophysical process, and no study has raised the possibility that ...

Meteorological excitation of the annual polar motion [PDF]
Geophysical Journal International, 1982 Summary. Numerous studies have indicated that the annual term in the polar motion cannot be explained in any detail by meteorological/hydrological excitation and no reasonable alternative excitations have been put forward. Part of the problem has been that the hydrostatic adjustment of the oceans to the atmospheric pressure changes has traditionally ...
