The physics of space weather/solar-terrestrial physics (STP): what we know now and what the current and future challenges are

open access: yesNonlinear Processes in Geophysics, 2020
. Major geomagnetic storms are caused by unusually intense solar wind southward magnetic fields that impinge upon the Earth's magnetosphere (Dungey, 1961). How can we predict the occurrence of future interplanetary events?

Cutting Through the Green: A Case for Grassland Archaeology Using UAV Multispectral Data

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Advances in low‐altitude remote sensing are needed to improve the effectiveness of archaeological prospection in the Netherlands. The geomorphological situation and land use history make applying various remote sensing and geophysical technologies particularly challenging.

Opposing consensus science through scholarly practices: The role of claims maintenance

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract This study examines how three US‐based communities who oppose consensus science produce and disseminate scholarly‐like artifacts: pro‐life activists, Young Earth Creationists, and Anthropogenic Climate Crisis skeptics. Prior research shows that industry‐ or church‐backed advocacy campaigns often generate claims supported by these communities ...

Physics of geospace storms

open access: yes, 2021
A review of our knowledge about the coupling of solar-terrestrial processes, manifestations of geospace storms, and variations in space weather is presented. Space weather effects are analyzed within the system paradigm concept. The system where geospace

The physics of premelted ice and its geophysical consequences [PDF]

open access: yesReviews of Modern Physics, 2006
The surface of ice exhibits the swath of phase-transition phenomena common to all materials and as such it acts as an ideal test bed of both theory and experiment. It is readily available, transparent, optically birefringent, and probing it in the laboratory does not require cryogenics or ultrahigh vacuum apparatus.

Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

open access: yesDeep Underground Science and Engineering, EarlyView.
In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

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

open access: yes, 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.

Geophysics guides particles physics

open access: yesEos, Transactions American Geophysical Union, 1988
When geophysicists from the Air Force Geophysics Laboratory (AFGL), Hanscom Air Force Base, Mass., presented evidence of a sixth fundamental force at the AGU Fall Meeting in San Francisco last month, an uncommon thing happened. Particle physicists responded, in t h e press and elsewhere, to a potential scientific breakthrough made by a group of earth ...
