The quasigeoid modelling in New Zealand using the boundary element method

Contributions to Geophysics and Geodesy, 2010
We compile a quasigeoid model at the study area of New Zealand using the boundary element method (BEM). The direct BEM formulation for the Laplace equation is applied to obtain a numerical solution to the linearized fixed gravimetric boundaryvalue ...

Geophysical Investigation of Geothermal Potential in Southern Thailand: Insights From GGMplus Gravity

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Southern Thailand hosts numerous low‐ to medium‐enthalpy geothermal manifestations in a non‐volcanic setting. This study investigates the geothermal potential of the region through the integration of satellite‐derived gravity data and geological observations.

A Transient Coastal Uplift Event Revealed by Pleistocene Marine Terraces Along the 2015 M8.3 Illapel Earthquake Rupture, Chile

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Uplifted Pleistocene marine terraces in the Illapel area along the forearc of central Chile record spatially and temporally variable uplift rates on glacial‐cycle timescales. However, the underlying mechanisms for this uplift variability and its potential relationship with the megathrust‐earthquake cycle remain poorly understood.

Assessment of EGM2008 over Sri Lanka, an area where 'fill-in' data were used in EGM2008 [PDF]

, 2009
The tide-free EGM2008 combined global geopotential model is compared with land and marine gravity observations and co-located GPS-levelling on and around Sri Lanka (formerly Ceylon).

Geração de mapas de anomalia Bouguer a partir de dados gravimétricos terrestres e do EGM2008 [PDF]

, 2017
Um dos propósitos da determinação da gravidade é a obtenção das anomalias da gravidade. O campo de gravidade é um campo potencial e sofre influência da constituição geológica, pois a densidade das rochas gera pequenas variações nos valores de gravidade ...

Flood Inundation Modeling Using the Surface Water Ocean Topography Mission

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Flood risk mapping requires detailed river bathymetry, yet these data are unavailable for most rivers. We propose a new algorithm to estimate river bathymetry from multitemporal observations of water height by the Surface Water and Ocean Topography (SWOT) mission.

Evaluation of the first GOCE static gravity field models using terrestrial gravity, vertical deflections and EGM2008 quasigeoid heights [PDF]

, 2011
Recently, four global geopotential models (GGMs) were computed and released based on the first two months of data collected by the GOCE (Gravity field and steady-state Ocean Circulation Explorer) dedicated satellite gravity field mission. Given that GOCE

To Which Extent the Surface Water Ocean Topography (SWOT) Mission Is Currently Able to Monitor Water Surface Elevation and Extent on the French Lakes?

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract This study (July 2023–December 2025) assesses the SWOT satellite's ability to measure water surface elevation (WSE) and surface water extent (SWE) over diverse French lakes. WSE estimates from SWOT were compared to in situ gauge data and conventional radar altimetry, while SWE was evaluated using the Global Water Watch (GWW) database.

Performance evaluation of the Earth Gravitational Model 2008 (EGM2008) – a case study

South African Journal of Geomatics, 2017
Ghana’s local geodetic reference network which is based on the War Office 1926 ellipsoid was established using astro-geodetic observations during the British Colonial era with data in latitude, longitude and orthometric height (𝜑,𝜆,𝐻) without the existence of ellipsoidal height.
