A Multi-Physics Experiment with a Temporary Dense Seismic Array on the Argentière Glacier, French Alps: The RESOLVE Project

, 2021
Recent work in the field of cryo-seismology demonstrates that high-frequency (>1  Hz) seismic waves provide key constraints on a wide range of glacier processes, such as basal friction, surface crevassing, or subglacial water flow.

POSEIDON: Physics-Optimized Seismic Energy Inference and Detection Operating Network

arXiv.org
Earthquake prediction and seismic hazard assessment remain fundamental challenges in geophysics, with existing machine learning approaches often operating as black boxes that ignore established physical laws.

Ultraviolet radiation physics in astronomy and geophysics

Journal of Quantitative Spectroscopy and Radiative Transfer, 1962
Abstract The astrophysicist has been compelled, in his studies of the solar and stellar atmospheres, to abandon in some cases the simpler “local thermodynamic equilibrium” approach. The new approach assumes statistical equilibrium and writes equations which concern the transfer of energy.

Rock Physics and Integrated Geophysical Methods

78th EAGE Conference and Exhibition 2016, 2016
Rock physics represents the background for integrating multidisciplinary geophysical data. In fact, some type of physical relationship is necessary for linking the different data and parameters in the seismic, gravity and electromagnetic domains. In this work, I discuss the different types of relationships and how these can be included in the objective

METRIC: A Dedicated Earth-Orbiting Spacecraft for Fundamental Physics and Geophysics

2018 5th IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace), 2018
A dedicated mission in low Earth orbit – called METRIC – is proposed to test selected predictions of gravitational theories and to measure directly the acceleration due to atmospheric drag in the altitude range considered, at the same time providing a metrological platform able to perform a tie between different space geodesy techniques.

Rock physics as the basis for inverting geophysical observations

SEG Technical Program Expanded Abstracts 2008, 2008
This is the first in a series of papers demonstrating the application of rock physics as the linchpin in inverting geophysical measurements to predict engineering and geologic rock and fluid properties. This paper establishes the importance of having accurate rock physics models for inversion.

Particula: A simulator tool for computational rock physics of granular media

Geophysics, 2019
Granular dynamics simulations provide insights to the contact-scale physics of loose sediments. However, simulations using identical spherical grains do not reflect characteristics observed in natural sediments, such as pack sorting, grading, grain ...
