The Role of the Overriding Plate and Mantle Viscosity Structure on Deep Slab Morphology
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.Abstract Using 2D numerical subduction models, we compare the morphology of deep slabs in the presence of an oceanic or continental overriding plate and viscosity jumps at either 660 km or 1,000 km depth as suggested by the latest geoid inversions. We demonstrate that a continental plate, combined with a 1,000 km depth viscosity increase, promotes slab

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.

Global atmospheric effects on the gravity field quantities
Contributions to Geophysics and Geodesy, 2009 We compile the global maps of atmospheric effects on the gravity field quantities using the spherical harmonic representation of the gravitational field. A simple atmospheric density distribution is assumed within a lower atmosphere (< 6 km). Dis-

MODERN METHODS OF DETERMINING PLUMBLINE AND GEOID SURFACE DEFERENCES
Urban development and spatial planningToday, global navigation satellite systems (GNSS) are widely used for the development of national geodetic networks and geodetic research. However, there are some applications where GNSS observations should be integrated with traditional ground-based ...

Global Assessment of Lake Surface Morphology and Its Impact on Water Volume Estimation
Water Resources Research, Volume 61, Issue 7, July 2025.Abstract Lake surface morphology, an essential yet underexplored feature of hydrological systems, remains poorly understood, including its effects on water volume estimation. This study investigates north‐south surface profiles of 147 lakes worldwide using ICESat‐2 altimetry data (2018–2024).

SWOT Water Surface Elevation in Herbaceous Wetlands of Florida's Everglades
Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract Observing water level variations in wetlands is important for tracking global water and carbon cycles. The Surface Water and Ocean Topography (SWOT) mission was launched to measure Earth's surface waters, but its performance in vegetated wetlands was unknown.

Recent Variability in Fracture Characteristics and Ice Flow of Thwaites Ice Shelf, West Antarctica
Journal of Geophysical Research: Earth Surface, Volume 130, Issue 5, May 2025.Abstract The rapidly changing Thwaites Ice Shelf is crucial for understanding ice‐shelf dynamical processes and their implications for sea‐level rise from Antarctica. Fractures, particularly their vertical structure, are key to ice‐shelf structural integrity but remain poorly measured.

Contributions to Geophysics and Geodesy, 2009 We compile global maps of the step-wise topography corrected and crustal components stripped geoids based on the geopotential model EGM’08 complete to spheri- cal harmonic degree 180 and the CRUST 2.0 global crustal model.
