Gap Formation Around 0.5 Omega(e) in the Whistler-Mode Waves Due To the Plateau-Like Shape in the Parallel Electron Distribution: 2D PIC Simulations
(2022-10-12)
The power gap around 0.5 Omega(e) (where Omega(e) is the equatorial electron gyrofrequency) of whistler-mode waves is commonly observed in the Earth's inner magnetosphere, but its generation mechanism is still under debate. ...
Assessing motivations, benefits, and barriers of implementing virtual field experiences in geoscience-related disciplines
(2025-04-02)
Outdoor field experiences have long been part of the traditional curriculum in geoscience-related disciplines and are considered a key aspect of professional development in these areas. When the COVID-19 pandemic forced ...
The U.S. educational effort in unsaturated zone hydrology
(2022-10-29)
The region of the earth below the land surface and above the water-saturated zone plays a major role in determining the behavior of hydrologic systems. To help educators and other interested individuals evaluate and continue ...
Petrology, Geochronology and Tectonic Setting of Early Triassic Alkaline Metagabbros From the Eastern Pontide Orogenic Belt (NE Turkey): Implications for the Geodynamic Evolution of Gondwana's Early Mesozoic Northern Margin
(2022-12-07)
The Triassic geodynamic evolution of the Pontides Belt, which geographically corresponds to northern Anatolia, is still a matter of debate. We present and interpret geological, petrographical, geochemical, and geochronological ...
Natural arsenic contamination of Holocene alluvial aquifers by linked tectonic, weathering, and microbial processes
(2022-10-26)
Linked tectonic, geochemical, and biologic processes lead to natural arsenic contamination of groundwater in Holocene alluvial aquifers, which are the main threat to human health around the world. These groundwaters are ...
Generation of rising-tone chorus in a two-dimensional mirror field by using the general curvilinear PIC code
(2022-10-12)
Recently, the generation of rising-tone chorus has been implemented with one-dimensional (1-D) particle-in-cell (PIC) simulations in an inhomogeneous background magnetic field, where both the propagation of waves and motion ...
New Valley Project
(2022-04-26)
This file contains a digital map of the New Valley Project (Egypt) in Google Earth KMZ format that was produced as part of The IBT Water Project at Auburn University. The New Valley Project, also known as Toshka Project, ...
Sedimentary charcoal morphometrics and morphologies of Ocean Drilling Program Site 1146
(2025-10-24)
The dataset contains sedimentary charcoal morphological and morphometric data, age (ka), depth (mcd), and charcoal accumulation rate ((#·cm)/(mg·Ma)) for Ocean Drilling Project Site 1146 Hole A and C.
