Horizontal Transport of Picture Gorge Basalt Magma Through the Monument Dike Swarm Determined by Magnetic Fabric

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract Flood basalts of the mid‐Miocene Columbia River Basalt Group (CRBG) cover 210,000 km2 of Washington, Oregon, and Idaho. The source of CRBG melt is debated; widely spaced feeder dike swarms can be projected toward hypothetical sources near the Oregon‐Idaho border.

Global Sporadic‐E Prediction and Climatology Using Deep Learning

open access: yesSpace Weather, Volume 23, Issue 5, May 2025.
Abstract Sporadic‐E Es $\left({E}_{s}\right)$ is an ionospheric phenomenon defined by strong layers of plasma which may interfere with radio wave propagation. In this work, we develop deep learning models to improve the understanding of Es ${E}_{s}$, including the presence, intensity and height of the layers. We developed three separate models.

Carbon and nutrient solubility in live and dead Betula pubescens leaves across a boreal retrogressive chronosequence

open access: yesOikos, Volume 2025, Issue 5, May 2025.
Leaching – the release of elements from organic matter through dissolution in water – plays an important role in biogeochemical cycling and ecosystem processes. However, our limited understanding of the patterns and underlying drivers of element solubility in leaves hinders accurate predictions of leaching over space and time in terrestrial ecosystems.

Reduction in Global Lightning Activity During the COVID Pandemic

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 8, 28 April 2025.
Abstract The effect of anthropogenic aerosols on lightning is one of the least understood aspects of human‐induced climate change. Global aerosol clearly diminished during the COVID pandemic by 7.6%. A pronounced decrease in global lightning activity in the range 3.0%–5.8% is identified from various detection systems during this natural experiment. The
