A Deep Ensemble Transformer Model for Global Ionosphere Prediction and Uncertainty Quantification

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Accurate global ionospheric forecasting is important for various purposes, from geophysical research to practical applications, including real‐time precise positioning and navigation. Existing studies primarily focus solely on deterministic predictions and often overlook uncertainty quantification.

Ionospheric Data Fusion With GNSS, GNSS‐RO and Satellite Altimetry Based on Machine Learning

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Global Ionospheric Maps (GIMs) are essential in Global Navigation Satellite System (GNSS) applications, particularly for correcting ionospheric delays in single‐frequency positioning. GIMs are mainly derived from dual‐frequency GNSS observations, but the uneven distribution of ground stations—sparse over oceans—reduces accuracy in these ...

Exploring Potential Mechanisms for the Initiation of Solifluction Patterns

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract Hillslopes in arctic regions commonly display large‐scale features—known as solifluction patterns—that form due to the exceedingly slow downhill movement of frost‐heaved soil. Here we use a combination of remote sensing data, linear stability analysis, numerical modeling, and review of a wide range of literature to evaluate several working ...

Sponges are celebrated heterotrophs but also key primary producers on changing coral reefs

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1561-1577, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Trophic interactions and nutrient cycling lay at the heart of ecosystem health and biodiversity. In recent years, our understanding of these drivers has been repeatedly challenged by rapid and unanticipated climatic effects, combined with an increasing awareness that ...

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

open access: yesAnimal Conservation, Volume 29, Issue 3, Page 235-248, June 2026.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...
