A dynamic model of Venus's gravity field [PDF]

Unlike Earth, long wavelength gravity anomalies and topography correlate well on Venus. Venus's admittance curve from spherical harmonic degree 2 to 18 is inconsistent with either Airy or Pratt isostasy, but is consistent with dynamic support from mantle

On the Crustal Architecture of the Terrestrial Planets

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Understanding the structure and composition of planetary crusts is fundamental for unraveling the diverse geologic pathways of rocky bodies in the solar system. In recent years, geophysical missions have shed light on the crustal architecture of the Moon and Mars.

Distribution of subglacial sediments across the Wilkes Subglacial Basin, East Antarctica [PDF]

, 2016
Topography, sediment distribution, and heat flux are all key boundary conditions governing the dynamics of the East Antarctic Ice Sheet (EAIS). EAIS stability is most at risk in Wilkes Land across vast expanses of marine-based catchments including the ...

Moho Depth Disposition of the Contiguous United States: A Multi‐Modal Data Driven Approach

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Precise determination of Moho depth is essential for understanding lithospheric deformation, lower crustal rheology, and crust‐mantle interactions. This study employs a Random Forest Regressor (RFR) model to predict Moho depth across the contiguous United States using a variety of geophysical data, including gravity anomalies, topography, heat

Comparisons of global topographic/isostatic models to the Earth's observed gravity field [PDF]

The Earth's gravitational potential, as described by a spherical harmonic expansion to degree 180, was compared to the potential implied by the topography and its isostatic compensation using five different hypothesis.

Raising the Roof of the World: Intra‐Crustal Asian Mantle Supports the Himalayan‐Tibetan Orogen

Tectonics, Volume 44, Issue 9, September 2025.
Abstract The Himalayan‐Tibetan orogen formed via the ongoing collision of India and Asia. Its colossal elevations stem from buoyant crustal roots that doubled in thickness during continental collision, widely believed to result from Indian crust under‐thrusting its Asian counterpart and Asian crustal thickening. However, a single crustal layer of up to

Dynamic compensation in the central Pacific Ocean [PDF]

The intermediate-wavelength geoid (lambda similar to 2000 km) and sea-floor topography fields in the central Pacific Ocean were studied in terms of static and dynamic compensation models.

Structure of the Dead Sea Pull-Apart Basin From Gravity Analyses [PDF]

, 1993
Analyses and modeling of gravity data in the Dead Sea pull-apart basin reveal the geometry of the basin and constrain models for its evolution. The basin is located within a valley which defines the Dead Sea transform plate boundary between Africa and ...

Early Cenozoic denudation of central west Britain in response to transient and permanent uplift above a mantle plume [PDF]

, 2018
Upwelling mantle plumes beneath continental crust are predicted to produce difficult to quantify, modest uplift and denudation. The contribution of permanent and transient components to the uplift is also difficult to distinguish.

GRAVSAT error analysis by means of global spectral analyses of the marine geoid from SEASAT altimeter data [PDF]

The geographical variability of short wavelength geoid power spectra (geoid roughness), was mapped for the world's oceans between latitudes 72 deg N and 72 deg S. A spectral analysis of SEASAT altimeter data, reduced to sea surface heights, was performed
