Influence of Melt Season Characteristics on Meltwater Partitioning and Delivery Into a Perennial Firn Aquifer

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Perennial firn aquifers in the Greenland ice sheet are known to form and persist in regions of sufficiently high melt rates and accumulation rates throughout the year. However, it is not clear how seasonal to sub‐seasonal variations in surface melt forcings affect the dynamics of melt recharge into a firn aquifer and the accompanying ...

Rupture Cascade Initiated by Wastewater Disposal: Nucleation and Domino Effect of Canada's Largest Induced Earthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract In 2022–2023, three local‐magnitude (ML) 4.8–5.6 earthquakes shook the Peace River oilsands area of Alberta, Canada. Previous studies statistically linked the seismicity to nearby disposal activities but lacked in‐depth investigation into triggering mechanisms, including subsurface fluid migration and earthquake interaction.

Freeze‐Thaw Processes Induce Convective Fingering in Saline Soils

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Saline soils in cold regions are often affected by freeze‐thaw processes, yet how these processes affect two‐dimensional salt transport dynamics remains poorly understood. Here, we show the importance of two‐dimensional flow induced by seasonal freeze‐thaw processes based on a validated numerical model.

Reproducing GRACE Total Water Storage Change at Finer Spatial Scales

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The Gravity Recovery and Climate Experiment (GRACE) satellite mission provides accurate observations of terrestrial water storage anomalies (TWSA), but their coarse spatial resolution (∼3°) limits sub‐regional‐scale applications. Existing downscaling methods rely on high‐resolution hydrometeorological inputs, which often underestimate the full
