Extreme Radiation Belt Dropout During the May 2024 Superstorm

open access: yesAGU Advances, Volume 7, Issue 6, September 2026.
Abstract The geomagnetic superstorm in May 2024 represents the most extreme space weather event over the past two decades, offering a unique opportunity to investigate radiation belt electron dynamics under exceptionally strong solar wind driving conditions. Observations from the Arase satellite show that relativistic electron fluxes dropped by several

Permeability, Pore Throat Size, Meteoric Influx, and Biomass Control the Depth‐Distribution of Microbial Biosignatures in Sedimentary Basin Fluids

open access: yesAGU Advances, Volume 7, Issue 6, September 2026.
Abstract The few studies of modern or ancient subsurface microbial communities beyond ∼100 m depth limit our view into the vast and complex deep terrestrial biosphere. In sedimentary systems, growing isotopic and molecular data sets of fluids, co‐produced with hydrocarbons, provide an unprecedented opportunity to evaluate the depth‐distribution of ...

Brine Pool Microbes Enrich Metalliferous Sediments in Salt Giant Basins

open access: yesAGU Advances, Volume 7, Issue 6, September 2026.
Abstract We report the discovery of an extinct deep‐sea brine pool in the Red Sea's Hume Deep, providing evidence that rift‐shoulder pools are ephemeral on millennial timescales, and that the microbially‐enriched metalliferous deposits produced during the pool's active phase persist into the stratigraphic record.

Impactful Datasets in Earth, Space, and Environmental Sciences: Highlighting the Data That Transform Research

open access: yesAGU Advances, Volume 7, Issue 6, September 2026.
Abstract The American Geophysical Union (AGU) announces the new living collection “Impactful Datasets in Earth, Space, and Environmental Sciences” which recognizes the creation and curation of datasets enabling research, analysis, and decision making beyond what is captured by traditional academic impact metrics.

A Sensitivity Analysis of Flick‐AccuRT, a Coupled Ocean‐Atmosphere Radiative Transfer Model and Input Module

open access: yesEarth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Radiative transfer (RT) models typically solve the radiative transfer equation separately in either the atmosphere or the ocean, limiting accuracy across the atmosphere‐ocean interface. Here, we employ a coupled scalar discrete ordinate RT model to examine methods for the input of measured inherent optical properties (IOPs) of oceanic ...
