Microimaging Spectroscopy of Carbonaceous Chondrites and Comparison to the Spectral Diversity of Asteroids

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Primitive asteroids and carbonaceous chondrites (CCs) record the history of processes in the early solar system. Visible and shortwave infrared (VSWIR) spectroscopy of primitive asteroids and bulk‐powdered CCs has identified shared spectral features suggestive of shared parent body origins.

Hydrologic Variability Drives Differential Methane Dynamics in Agricultural Reservoirs of the Northern Great Plains

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Climate variability can regulate aquatic methane fluxes as increasing temperatures can elevate microbial metabolic rates, including methanogenesis. It is less well known how climate‐induced variability in seasonal precipitation and runoff might affect methane concentrations and fluxes in aquatic ecosystems.

Segmentation and Tracking of Eruptive Solar Phenomena With Convolutional Neural Networks

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Solar eruptive events are complex phenomena, which most often include coronal mass ejections (CME), CME‐driven compressive and shock waves, flares, and filament eruptions. CMEs are large eruptions of magnetized plasma from the Sun's outer atmosphere or corona, that propagate outward into the interplanetary space.
