Automated Burris gravity meter for single and continuous observation

The Burris Gravity Meter™ manufactured by ZLS Corporation, Austin/Texas, USA, is based on the invention of L&R (L. LaCoste and A. Romberg): The ZLS (zero-length spring). A digital feedback system (range of about 50 mGal) is used to null the...

Turbulence properties and kinetic signatures of electrons in Kelvin-Helmholtz waves during a geomagnetic storm

The Kelvin–Helmholtz instability (KHI), in its nonlinear phase, plays a significant role in transporting solar-wind plasma into Earth’s magnetosphere. This study investigates the turbulence properties and reconnection signatures observed at...

Terrestrial Remote Sensing of Snowmelt in a Diverse High-Arctic Tundra Environment Using Time-Lapse Imagery

Snow cover is one of the crucial factors influencing the plant distribution in harsh Arctic regions. In tundra environments, wind redistribution of snow leads to a very heterogeneous spatial distribution which influences growth conditions f...

Assessment of climate change impact on wheat crop using MarkSim GCM in Varanasi, Uttar Pradesh

GFLD-CM3 model was used to generate weather data under RCPs scenario i.e. RCP 2.6, 4.5, 6.0 and 8.5 for years 2010, 2035, 2065 and 2095 for Varanasi, Uttar Pradesh. The generated data were used to assess the impact of climate change on phen...

Settlement process of radioactive dust to the ground inferred from the atmospheric electric field measurement

Radioactive materials from the accident at Fukushima Dai-ichi nuclear power plant (FNPP) in March 2011 spread over a large area, increasing the atmospheric electric conductivity by their ionizing effect, and reducing the vertical (downwa...

The impact of earthquakes on the regime of ultra-low-frequency electromagnetic emissions

Anomalous changes in the behavior of Pc 1 geomagnetic pulsations and oscillations with the spectrum resonance structure (SRS) occurred a few minutes before or after an earthquake have been found. In all cases the changes happened following ...

The Integrity and Tightness of Underground Hydrogen Storage Systems: A Critical Review of Geological Barriers, Well Sealing, Leakage Risks and Future Perspectives

Underground storage of green hydrogen is a strategic enabler of large-scale renewable deployment, but its feasibility rests on a hard problem: keeping a small, highly mobile molecule confined underground for decades without safety or enviro...

Water Tank Experiments on Stratified Flow over Double Mountain-Shaped Obstacles at High-Reynolds Number

In this article, we present an overview of the HyIV-CNRS-SecORo (Hydralab IV-CNRS-Secondary Orography and Rotors Experiments) laboratory experiments carried out in the CNRM (Centre National de Recherches Météorologiques) large stratified wa...

top-ii-vol: Massively Parallel Scalable Meshing for Seismic Risk Assessment of Nuclear Sites

High performance computing is widely used for conducting high-resolution geophysics Finite Element Method (FEM) simulations. These simulations are crucial for risk assessment at nuclear sites and help gain deeper insights into underlying ph...

THE OVERVIEW OF THE PLANETARY ATMOSPHERIC SPECTRAL TELESCOPE (PAST) IN THE SCIENTIFIC EXPERIMENTAL SYSTEM IN NEAR-SPACE (SENSE)

To investigate mass transport and energy dissipation in space environments for solar system planet, a balloon-borne planetary atmospheric spectral telescope (PAST) is designed with 0.8-m aperture in spectral range from 280 nm to 680&...

Crustal rheology controls on the Tibetan plateau formation during India-Asia convergence

Tibetan plateau deformation is variable, but what controls those variations is still poorly understood. Here, the authors use 3D numerical models to show that the variations observed in lithosphere deformation are controlled by heterogeneit...

Distribution and Abundance of Solar Wind‐Derived Water in Chang'E‐5 Core Samples and Its Implications

Abstract Knowledge regarding the abundance and distribution of solar wind (SW)‐sourced water (OH/H2O) on the Moon in the shallow subsurface remains limited. Here, we report the NanoSIMS measurements of H abundances and D/H ratios on soil gr...

Temporal and Spatial Analysis of Coastal Landscape Patterns Using the GEE Cloud Platform and Landsat Time Series

Owing to the rapid urbanization combined with global climate change, dramatic land-use change in coastal watersheds is occurred, which, in turn, cause the evolution of landscape patterns and threaten the valuable but fragile ecosystem. The ...

The mechanism of excavation-induced rockbursts in ultra-thick soft-hard composite coal seams at shallow depths: an experimental study

Abstract Ultra-thick soft-hard (UTSH) composite coal seams, composed of alternating layers of soft and hard coal, frequently experience severe rockburst accidents during roadway excavation under shallow burial depths (...

Internal Water Facilitates Thermal Resetting of Clumped Isotopes in Biogenic Aragonite

Abstract Biogenic and inorganic calcium carbonates contain considerable amounts of internal water, both as free and organically associated water. The oxygen isotopic compositions (δ18O) of internal water and hosting carbonate are analyzed f...

Spatial random downscaling of rainfall signals in Andean heterogeneous terrain

Remotely sensed data are often used as proxies for indirect precipitation measures over data-scarce and complex-terrain areas such as the Peruvian Andes. Although this information might be appropriate for some research requirements, the ext...

The surface temperatures of Earth: steps towards integrated understanding of variability and change

Surface temperature is a key aspect of weather and climate, but the term may refer to different quantities that play interconnected roles and are observed by different means. In a community-based activity in June 2012, the EarthTemp Network...

High P‐T Sound Velocities of Amphiboles: Implications for Low‐Velocity Anomalies in Metasomatized Upper Mantle

Abstract Metasomatized mantle xenoliths containing hydrous minerals, such as amphiboles, serpentine, and phlogopite, likely represent the potential mineralogical compositions of the metasomatized upper mantle, where low seismic velocities a...

A Review on Modeling Environmental Loading Effects and Their Contributions to Nonlinear Variations of Global Navigation Satellite System Coordinate Time Series

Nonlinear variations in the coordinate time series of global navigation satellite system (GNSS) reference stations are strongly correlated with surface displacements caused by environmental loading effects, including atmospheric, hydrologic...
