Ice Nucleation Enhancement in Ambient Aerosols Under High‐Salinity Conditions: Insights From Cloud Chamber Experiments

Abstract Ice‐nucleating particles (INPs) play a role in mixed‐phase clouds, yet the processes controlling their properties remain poorly understood. Water‐soluble salts such as sodium chloride (NaCl) depress the freezing temperature of clou...

The Beginning of a Wilson Cycle in an Accretionary Orogen: The Mongol–Okhotsk Ocean Opened Assisted by a Devonian Mantle Plume

Abstract The opening of oceans within accretionary orogens is important for understanding the Wilson cycle. The Mongol–Okhotsk Ocean (MOO) began opening within the early Paleozoic accretionary collage of the Central Asian Orogenic Belt (CAO...

Reservoir geophysics

Abstract The concept of petroleum reservoir geophysics is relatively new. In the past, the role of geophysics was largely confined to exploration and, to a lesser degree, the development of discoveries. As cost-efficiency has taken over as ...

Fractal aggregates in geophysics

The combination of small particles to form larger structures is important in a broad range of natural processes, including the flocculation of organic and mineral particles in rivers, estuaries, and the open sea, the growth of smoke particl...

Green’s functions for geophysics: a review

The Green's function (GF) method, which makes use of GFs, is an important and elegant tool for solving a given boundary-value problem for the differential equation from a real engineering or physical field. Under a concentrated source, the ...

Integrated geochemical evaluation of hydrocarbon source potential in late quaternary sediments of the Nkhata basin, Malawi

Abstract The Nkhata basin located in the central part of the Malawi rift consists of Late Quaternary (Chibanian to present;  6.02 wt% and S2 > 25.55 mg HC/g rock; 1 C: TOC up to 6.16 wt%, S2 up to 56.9 mg HC/g rock). The sediments were domi...

Comparison of the GOSAT TANSO-FTS TIR CH volume mixing ratio vertical profiles with those measured by ACE-FTS, ESA MIPAS, IMK-IAA MIPAS, and 16 NDACC stations

The primary instrument on the Greenhouse gases Observing SATellite (GOSAT) is the Thermal And Near infrared Sensor for carbon Observations (TANSO) Fourier transform spectrometer (FTS). TANSO-FTS uses three short-wave infrared (SWIR) band...

A novel method for imitating true-triaxial stress path with conventional triaxial apparatus

Abstract The stress paths of the cylindrical specimen in the p–q stress space by controlling the ratio of the axial and the radial loading is guaranteed to be consistent with the cuboid specimen, a novel method for imitating true-triaxial s...

Surface and Subsurface Biogeochemical Impacts of the 2019 Northeast Pacific Marine Heatwave

Abstract Following the highly impactful 2013–2016 Marine Heatwave (MHW), another MHW occurred in the Northeast Pacific during summer 2019. While the physical drivers of this event are well described, its biogeochemical impacts remain poorly...

Shear Wave Splitting and Mantle Flow in Mexico: What Have we Learned?

El presente artículo es un resumen y análisis de los estudios de partición de ondas transversales (shear wave splitting) para el manto superior que se han realizado en México durante la última década. Cuando una onda sísmica entra en un med...

A geotechnical investigation on a recent gigantic rock avalanche at the Patalganga-Langsi site on the Badrinath highway of chamoli, Uttarakhand (Garhwal Himalaya), India

Abstract Garhwal Himalaya is one of the most landslide-prone regions in the Himalayan Belt due to its seismo-tectonic background, geological complexity, climate, geomorphological setting and large-scale human interference. A gigantic rock a...

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...

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...

Modernizing GNSS data acquisition, pre-processing, and distribution at volcanological observatories

In recent years, the field of geodetic monitoring is undergoing a profound transformation driven by the transition from GPS-only positioning to a fully multi-GNSS environment. With Galileo, BeiDou, and modernized GPS & GLONASS constella...

Fractals and Chaos in Geology and Geophysics

The fundamental concepts of fractal geometry and chaotic dynamics, along with the related concepts of multifractals, self-similar time series, wavelets, and self-organised criticality, are introduced in this book, for a broad range of reade...

Green synthesis of silver nanoparticles using terrestrial fern (Gleichenia Pectinata (Willd.) C. Presl.): characterization and antimicrobial studies

Novel silver nanoparticles from Gleichenia Pectinata (Willd.) C. Presl. was synthesized. A combination of spectroscopic and microscopic techniques were utilized to characterize the newly synthesized Gleichenia Pectinata Silver Nanoparticles...

Weed Management by In Situ Cover Crops and Anaerobic Soil Disinfestation in Plasticulture

Weeds negatively affect organic vegetable crop growth and profitability. Weed management is the greatest challenge for vegetable organic growers since control options are limited for organic vegetable production. Anaerobic soil disinfestati...
