Fire‐EnSF: Data Assimilation for Wildfire Spread Models Using Ensemble Score Filter

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract As wildfires become increasingly destructive and expensive to control, effective management of active wildfires requires accurate and real‐time fire spread predictions. To enhance the forecasting accuracy of active fires, data assimilation plays a vital role by integrating observations (such as remote‐sensing data) and fire predictions ...

Spatial Variability and Long‐Term Trends in Winter Phytoplankton of the Warming Eastern Mediterranean Sea

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract The Eastern Mediterranean Sea (EMS) is among the fastest‐warming ocean regions, but the impacts of this warming on phytoplankton are unclear. Here, wintertime field observations were conducted across the EMS. These observations showed that small photosynthetic eukaryotes (<20 μm) dominated phytoplankton communities, collectively accounting for

Daily Global Methane Super‐Emitter Detection and Source Identification With Sub‐Daily Tracking

Geophysical Research Letters
We use the Visible Infrared Imaging Radiometer Suite (VIIRS) satellite instruments to retrieve atmospheric methane enhancements with 750 m resolution. We show that the three VIIRS instruments in orbit uniquely enhance tracking of methane super‐emission ...

Amazon River Plume Control on Carbonate Chemistry in the Western Tropical Atlantic

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract The Amazon River Plume (ARP) modulates the carbonate system of the western Tropical Atlantic (WTA) through physical and biological processes, including freshwater dilution, biological carbon uptake, and circulation‐driven transport; however, its basin‐scale impact has not been quantitatively assessed.

Microbial Respiration Across Subtropical Eddies: Submesoscale Variability and Biogeochemical Drivers

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Island‐induced eddies from the Canary Islands region propagate southwestward along the Canary Eddy Corridor, exporting biological and biogeochemical properties to the oligotrophic open ocean. However, their contribution to organic matter remineralization, and consequently to the biological carbon pump, throughout their life cycle remains ...
