High precision vertical gravity gradient determination in Croatia [PDF]

open access: yesActa Geodaetica et Geophysica, 2015
The paper depicts high precision vertical gravity gradient determination for the purpose of height reduction in order to connect absolute gravity determinations and high precision relative gravity measurements. Measurements were performed with two Scintrex Autograv CG-3M gravity meters at two absolute gravity stations.

Refining geoid and vertical gradient of gravity anomaly

open access: yesGeodesy and Geodynamics, 2011
We have derived and tested several relations between geoid (N) and quasi-geoid (ζ) with model validation. The elevation correction consists of the first-term (Bouguer anomaly) and second-term (vertical gradient of gravity anomaly).

Study of a vertical gravity gradient at the MUT area [PDF]

open access: yesBiuletyn Wojskowej Akademii Technicznej, 2023
Any object on the globe, in addition to the gravitational force, is affected by the force associated with the rotation of the Earth, i.e., the centrifugal force, which together define the force of gravity.

Refined prediction of vertical gradient of gravity at Etna volcano gravity network (Italy)

open access: yesContributions to Geophysics and Geodesy, 2018
Predicted values of the vertical gradient of gravity (VGG) on benchmarks of Etna’s monitoring system, based on calculation of the topographic contribution to the theoretical free-air gradient, are compared with VGG values observed in situ.

An Expression for Gravity Generated by an Anomalous Geological Body and Its Application in Bathymetry Inversion [PDF]

open access: yesJournal of Geodesy and Geoinformation Science, 2021
The gravity anomaly and vertical gravity gradient due to anomalous geological bodies are mainly computed by numerical methods, so it is difficult and time-consuming to use the gravity-geological method to invert seafloor topography.

Comparative Study on Predicting Topography from Gravity Anomaly and Gravity Gradient Anomaly

open access: yesRemote Sensing, 2023
Owing to the dependence of algorithms on the measurement of ship soundings and geophysical parameters, the accuracy and coverage of topography still need to be improved. Previous studies have mostly predicted topography using gravity or gravity gradient,

Seafloor Topography Estimation from Gravity Anomaly and Vertical Gravity Gradient Using Nonlinear Iterative Least Square Method

open access: yesRemote Sensing, 2020
Currently, seafloor topography inversion based on satellite altimetry gravity data provides the principal means to predict the global seafloor topography. Researchers often use sea surface geoid height or gravity anomaly to predict sea depth in the space

Ocean dynamic equations with the real gravity

open access: yesScientific Reports, 2021
Two different treatments in ocean dynamics are found between the gravity and pressure gradient force. Vertical component is 5–6 orders of magnitude larger than horizontal components for the pressure gradient force in large-scale motion, and for the ...
