A high-resolution gravimetric geoid model for Japan from EGM2008 and local gravity data [PDF]
Earth, Planets and Space, 2012 A high-resolution geoid model covering the four main islands of Japan has been developed on a 1 by 1.5 arc-minute grid from EGM2008 and terrestrial gravity data. The Stokes-Helmert scheme in a modified form is applied for the determination of the geoid using an empirically-determined optimal spherical cap, and Kriging is used for gridding the residual ...

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.

Adaptation of a tridimensional gravimetric model to the North Patagonian Massif area [PDF]
, 2013 El Macizo Norpatagónico es una altiplanicie que casi no presenta deformación rodeada de cuencas con distintos grados de deformación terciaria sobre las cuales sobresale entre 500 y 700 metros. Dicho macizo sufrió un levantamiento repentino de más de 1200

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.

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 ...

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 ...

Earth and Space Science, Volume 12, Issue 7, July 2025.Abstract The launch of the Surface Water and Ocean Topography (SWOT) satellite in December 2022 started a new era of swath altimetry, introducing an unprecedented global data set of high‐resolution two‐dimensional water level imagery. During its initial calibration and validation phase (cal/val), SWOT conducted daily observations for 3 months providing

Geração de mapas de anomalia Bouguer a partir de dados gravimétricos terrestres e do EGM2008
Revista Brasileira de Geomática, 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 ...

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).
