Carbonate‐Associated Sulfate Does Not Record Superheavy δ34S in Deep Scandinavian Bedrock Fractures: Implications for Pyrite Formation in the Deep Biosphere

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract In deep bedrock fractures of the Fennoscandian shield, pyrite with “superheavy” δ34S values of up to 147‰ exists together with calcite. The extreme variability and 34S‐enrichment in pyrite indicate that microbial sulfate reduction (MSR) evolved to almost complete sulfate exhaustion in closed‐system microenvironments.

Super‐Resolution of Planetary Images Based on Generative Adversarial Network

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Currently, satellite imagery serves as the primary means of observing terrestrial planets such as the Mars, the Moon, and Mercury. Enhancing the resolution and quality of these images can provide more detailed insights into planetary surfaces. However, improvements in image quality are often limited by the constraints of sensor technology and ...

Automated Mineral Identification and Rock‐Type Classification of Lunar Mare Basalts Using SEM Images

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We present an automated system for identifying minerals and classifying rock types in Apollo lunar mare basalts using scanning electron microscopy (SEM) imagery. Mineral segmentation is based on a U‐Net architecture, supplemented by two scale‐aware models designed to incorporate pixel size information.

Localization and Classification of Gravity Wave Events From VIIRS Day/Night Band Satellite Imagery Using Machine Learning Techniques

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Gravity waves in the upper mesosphere produce diverse spatial patterns in nighttime airglow, but their global morphology has been difficult to characterize because manual identification is impractical for the massive satellite image archive. We developed a machine learning framework to detect and classify gravity wave events in imagery from ...

Precipitation Intensity Increased Across the South Pacific Convergence Zone in the Industrial Age

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The position, strength, and variability of precipitation in the South Pacific Convergence Zone (SPCZ) remain challenging for coupled ocean‐atmosphere climate models to represent, leaving future rainfall projections in this dynamically important region uncertain.

Accelerating Ground‐Based Aerosol Retrieval From Shortwave Radiation Using Tabular Foundation Models

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Retrieving aerosol optical properties from broadband surface solar radiation measurements presents a challenging inverse problem that has yet to be fully explored. This study presents a novel framework using optimal estimation (OE) to retrieve aerosol optical depth (AOD) and Ångström exponent, which subsequently serve as regression targets for
