An Atomic Gravitational Wave Interferometric Sensor in Low Earth Orbit (AGIS-LEO)

open access: yes, 2010
We propose an atom interferometer gravitational wave detector in low Earth orbit (AGIS-LEO). Gravitational waves can be observed by comparing a pair of atom interferometers separated over a ~30 km baseline.

High‐Precision Delineation of Curie Point Depth Under Remanent Magnetization Using Physics‐Informed Neural Networks

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The Curie point depth (CPD), a key indicator of the lithosphere's thermal structure, is typically estimated using spectral analysis or interface inversion methods. However, these approaches often neglect the effects of remanent magnetization, leading to substantial uncertainty.

Exploring the Gravimetric and Geochronological Links in Ancient Terranes of the São Francisco Craton and Borborema Province, NE‐Brazil

open access: yesTerra Nova, Volume 38, Issue 2, Page 77-86, April 2026.
ABSTRACT Deep crustal fragments and structural lineaments identified through satellite gravity data provide evidence for the extension of the reworked ancient basement of the Central African Block into the northern São Francisco Craton and southern Borborema Province.

The road toward a general relativistic metric inside the Earth and its effect on neutrino travel from CERN to GRAN-SASSO Laboratory [PDF]

open access: yes, 2012
In a first attempt to describe the effect on neutrino travel inside the Earth caused by general relativity in the case of a dense Earth, we have neglected the Earth's rotation, the Earth's ellipticity and also the surface terrain variation, nevertheless ...

Structural setting of the Koum sedimentary basin (north Cameroon) derived from EGM2008 gravity field interpretation

open access: yesContributions to Geophysics and Geodesy, 2018
This study is a contribution to the planning of hydrocarbon exploration program of the Koum sedimentary basin in North Cameroon. 3D modeling of WGM2012 gravity data derived from EGM2008 geopotential model in the Koum basin was used together with existing

Quantifying river morphological changes using multi‐satellite observations and in situ measurements

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
This study integrates optical, radar and altimetry satellite data with river gauge measurements to estimate periodically submerged riverbed topography and quantify morphological change. By linking how often water covers the riverbed with water‐level variations, erosion and deposition patterns are mapped across a reach of Jamuna River.

Avaliação da correção gravimétrica do terreno calculada a partir de Modelos Digitais de Elevação e associados ao Sistema Geodésico Brasileiro e ao EGM2008

open access: yesRevista Agrogeoambiental, 2011
A avaliação dos curtos comprimentos de onda do geopotencial normalmente está vinculada aos efeitos gravimétricos da topografia do terreno. Em vista da ausência de informação altimétrica em resolução adequada, utilizam-se modelos digitais de elevação, os ...

Evaluating two numerical methods for developing a local geoid model and a local digital elevation model for the Red Sea Coast, Egypt

open access: yesJournal of King Saud University: Engineering Sciences, 2023
Global Navigation Satellite System (GNSS) provides ellipsoidal heights, whereas engineering projects need orthometric heights of points. Thus, to take advantage of GNSS in engineering work, the relation between orthometric and ellipsoid height must be ...

Tracking Baseflow Supply Dynamics Using SWOT Data From Small Groundwater‐Dominated Lakes

open access: yesHydrological Processes, Volume 40, Issue 2, February 2026.
Satellite‐based measurements of groundwater flow‐through kettle lakes efficiently track dynamic groundwater storage at local to regional scales (modified from USGS Scientific Investigations Report 2011–5137). ABSTRACT In situ surface‐water monitoring strategies are biased towards larger perennial streams and lakes and are generally not designed to ...
