A new combined quasigeoid model in Tierra del Fuego [PDF]

, 2014
This work focuses on the development of a combined quasigeoid model for Tierra del Fuego province. The Equivalent Source Technique (EST) is applied together with the remove-compute-restore technique in order to combine gravity and GPS/levelling ...

Subduction‐Driven Reworking of Craton and Accretionary Orogen: Evidence From Integrated Geophysical Imaging in Western North China Craton

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Observations and interpreted mechanisms for the reworking of Precambrian cratons and accretionary orogens have significant relevance in understanding the history and evolution of continental lithosphere. Here we investigate the Precambrian basement and lithospheric architecture of the western North China craton (NCC) through the integration of

Towards the Selection of an Optimal Global Geopotential Model for the Computation of the Long-Wavelength Contribution: A Case Study of Ghana

Geosciences, 2017
The selection of a global geopotential model (GGM) for modeling the long-wavelength for geoid computation is imperative not only because of the plethora of GGMs available but more importantly because it influences the accuracy of a geoid model.

Structure of the Ecuadorian Upper Plate From a Joint Seismic‐Gravity Inversion

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract The Ecuadorian portion of the South American subduction zone presents an interesting case study in the structure and complex evolution of an upper plate. There are outstanding questions about its tectonic history, composition, and magmatic processes.

Numerical simulations of the nonlinear Molodensky problem [PDF]

, 2013
We present a boundary element method to compute numerical approximations to the non-linear Molodensky problem, which reconstructs the surface of the earth from the gravitational potential and the gravity vector.

A Gravity Study of the Crustal Structure Beneath the Young Amagmatic Rukwa‐Tanganyika Rift Zone

Tectonics, Volume 44, Issue 8, August 2025.
Abstract The Rukwa‐Tanganyika Rift Zone (RTRZ), experiencing multiphase rifting, forms the nonvolcanic southern part of the Western Branch of the East African Rift. We investigate the crustal structure beneath the RTRZ to understand how strain migrates beneath multiphase rifts.

Crustal and Upper Mantle Density Structure Beneath the Qinghai-Tibet Plateau and Surrounding Areas Derived from EGM2008 Geoid Anomalies

ISPRS International Journal of Geo-Information, 2016
As the most active plateau on the Earth, the Qinghai-Tibet Plateau (TP) has a complex crust–mantle structure. Knowledge of the distribution of such a structure provides information for understanding the underlying geodynamic processes.

Gravity anomalies and lithospheric flexure around the Longmen Shan deduced from combinations of in situ observations and EGM2008 data

Earth, Planets and Space, 2016
The current work describes the combined data of three field campaigns, spanning 2009–2013. Their joint gravity and GPS observations thoroughly cover the sites of lithospheric flexure between the Sichuan Basin and the Eastern Tibetan Plateau.

SWOT Reveals Detailed Dynamics of Longitudinal River Slope in the Missouri River Basin

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract River water surface slope (WSS) is a crucial variable for a wide range of studies in hydrology, hydraulics, and morphology. However, current in situ and remote sensing methods have limitations in characterizing the WSS of global river systems. Here, we present an exploration of SWOT satellite data for studying WSS and longitudinal profiles in ...
