Estimation and Attribution of Horizontal Land Motion Measured by the Greenland GNSS Network

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Horizontal land motion, as observed by geodetic techniques such as Global Navigation Satellite Systems (GNSS), is generally dominated by tectonic plate movement. However, in regions that are currently or formerly glaciated, such as Greenland, the deformation of the solid Earth due to surface loading complicates the separation of tectonic and ...

Effects of the Last Quaternary Glacial Forebulge on Vertical Land Movement, Sea‐Level Change, and Lithospheric Stresses

Reviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract A glacial forebulge is a bending‐related upheaval of the lithosphere outside a glaciated area that co‐occurs to the depression of the lithosphere below an ice sheet. The forebulge of the last glaciation attracted attention over more than one century, but quantitative descriptions on the geometry of the forebulge are rare.

Normal gravity field in relativistic geodesy

, 2018
Modern geodesy is subject to a dramatic change from the Newtonian paradigm to Einstein's theory of general relativity. This is motivated by the ongoing advance in development of quantum sensors for applications in geodesy including quantum gravimeters ...

A GPS network for tropospheric tomography in the framework of the Mediterranean hydrometeorological observatory Cévennes-Vivarais (south-eastern France) [PDF]

, 2014
International audienceThe Mediterranean hydrometeorological observatory Cévennes-Vivarais (OHM-CV) coordinates hydrometeorological observations (radars, rain gauges, water level stations) on a regional scale in southeastern France.

Inferring Long‐Term Geocenter Motion From Low‐Degree Gravity Field

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Accurate determination of geocenter motion is essential not only for establishing a stable terrestrial reference frame, but also for deriving a complete picture of large‐scale global mass redistribution in the Earth system. For geophysical applications, reliable geocenter motions can be inferred from time‐variable gravity fields provided by ...

A Comparative Study of the Applied Methods for Estimating Deflection of the Vertical in Terrestrial Geodetic Measurements

Sensors, 2016
This paper compares three different methods capable of estimating the deflection of the vertical (DoV): one is based on the joint use of high precision spirit leveling and Global Navigation Satellite Systems (GNSS), a second uses astro-geodetic ...

Concept of spatial coordinate systems, their defining and implementation as a precondition in geospatial applications [PDF]

Glasnik Srpskog Geografskog Društva, 2015
There are many users of spatial information, and quite large interest about the nature and genesis of such information. Different users found spatial information in the form of maps, plans or alphanumerical tables. Recently, there are more often

Inferring Tectonic Plate Rotations From InSAR Time Series

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Interferometric Synthetic Aperture Radar (InSAR) provides constraints on lithospheric kinematics at high spatial resolution. Interpreting InSAR‐derived deformation maps at continental scales is challenged by long‐wavelength correlated noise and the inherent limitation of measuring relative displacements within the data footprint.

A comparison of established and digital surface model (DSM) ‐based methods to determine population estimates and densities for king penguin colonies, using fixed‐wing drone and satellite imagery

Remote Sensing in Ecology and Conservation, Volume 11, Issue 3, Page 294-311, June 2025.
We used fixed‐wing drones and Beyond Visual Line of Sight flying to create high‐resolution imagery and Digital Surface Models (DSMs) of six large king penguin colonies (colony population sizes ranging from 10,671 to 132,577 pairs) in South Georgia. We used a novel DSM‐based method to facilitate automated and semi‐automated counts of each colony to ...

Plate‐Scale Strike‐Slip Fault System in the Barbados Accretionary Wedge of the Lesser Antilles Subduction Zone

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Fault systems of various geometries develop into accretionary wedges to accommodate slip partitioning of plate convergence in oblique settings. However, how they form, evolve and contribute to the segmentation of the megathrust is still poorly understood. The Barbados accretionary wedge, which results from the subduction of the American plates
