Secular polar motion observed by GRACE. [PDF]
J Geod, 2021 AbstractA long-term drift in polar motion (PM) has been observed for more than a century, and Glacial Isostatic Adjustment (GIA) has been understood as an important cause. However, observed PM includes contributions from other sources, including contemporary climate change and perhaps others associated with Earth’s interior dynamics.

Formation and motion of a transpolar arc in response to dayside and nightside reconnection [PDF]
, 2005 We trace the formation and subsequent motion of a transpolar arc in response to dayside and nightside reconnection. Both high- and low-latitude dayside reconnection are observed, as well as periods of substorm and nonsubstorm nightside reconnection ...

The polar sciences journal: the past and future of a crucial research instrument [PDF]
, 2022 Journals dedicated to the polar sciences have been outliers. Within both the history of science and the history of media, they stand out in several ways, including their comparatively late establishment of peer-review. It was not until the second half of

Is the Earth’s Magnetic Field a Constant? A Legacy of Poisson
Geosciences, 2023 In the report he submitted to the Académie des Sciences, Poisson imagined a set of concentric spheres at the origin of Earth’s magnetic field. It may come as a surprise to many that Poisson as well as Gauss both considered the magnetic field to be ...

Assimilation of Earth rotation parameters into a global ocean model: excitation of polar motion [PDF]
Nonlinear Processes in Geophysics, 2011 The oceanic contribution to Earth rotation anomalies can be manifold. Possible causes are a change of total ocean mass, changes in current speed or location and changes in mass distribution.

Effects of the Earth’ s triaxiality on the polar motion excitations
Geodesy and Geodynamics, 2012 his study aims to evaluate the significance of the Earth’s triaxiality to the polar motion theory. First of all, we compare the polar motion theories for both the triaxial and rotationally-symmetric Earth models, which is established on the basis of the ...

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 ...

Study of Convolutional Neural Networks for Global Parametric Motion Estimation on Log-Polar Imagery
IEEE Access, 2020 The problem of motion estimation from images has been widely studied in the past. Although many mature solutions exist, there are still open issues and challenges to be addressed.
