Frozen Ground Induces Seawater Retreat in Coastal Unconfined Aquifers

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract While seawater intrusion (SWI) in coastal aquifers has been extensively investigated, most studies focused on unfrozen conditions. In many cold regions, frozen ground is common, yet its impact on SWI remains poorly understood. Here, we demonstrate that the formation of frozen ground alters salinity distribution in coastal unconfined aquifers ...

Study of hydrothermal processes in ice-layers subgrade under constant temperature and dynamic loading

Scientific Reports
The presence of ice-layers in the subgrade soils makes the hydrothermal state of road subgrade built in island permafrost regions more susceptible to external environmental influences.

Thinking Outside the Rocks: Subsurface Water Storage, Topography, and Land Cover Are Key Modulators of Large‐Scale Riverine Dissolved Silicon Dynamics

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Riverine dissolved silicon (DSi) dynamics reflect integrated geologic, hydrologic, climatic, and ecological controls. We compiled annual DSi data for 337 rivers across four continents and trained interpretable machine‐learning models to predict concentrations and yields from 28 watershed variables.

Permafrost Thaw Dynamics Drive the Regime Shifts of Iron‐Bound Organic Carbon Sequestration in the East Siberian Arctic Shelf

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract In the changing Arctic, permafrost thaw is shifting from gradual to abrupt. Although iron‐bound organic carbon (OC‐FeR) critically modulates permafrost carbon‐climate feedbacks, its decadal‐scale variability and response to this regime shift remain poorly constrained.

Evolution of Near‐Term Atmospheric Methane and Associated Temperature Response Under the Global Methane Pledge: Insights From an Earth System Model

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Methane is a powerful greenhouse gas with a shorter lifetime than carbon dioxide (CO2), making it an important target for near‐term climate action. The Global Methane Pledge (GMP) aims to cut anthropogenic methane emissions by 30% from 2020 levels by 2030. Using an Earth system model with interactive CH4 sources and sinks, we assess the Pledge'

Low‐Frequency Polarization of Blank Ice Features in Solid Rocks

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract For hydrogeological management of seasonally frozen soils, or permafrost, the quantification of ice and water content is key. Changes in electrical conductivity are commonly used to monitor ice‐to‐water ratios but hard rocks, ice and air are all highly resistive materials.

Water Storage Changes of Lakes and Reservoirs Across Asia (2018–2023) and Their Effects in Flood Control

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Monitoring lake and reservoir water levels is critical for water resource management and flood risk mitigation. We integrate Sentinel‐3A/B and ICESat‐2 altimetry to reconstruct monthly water levels (2018–2023) for 7,433 lakes and reservoirs (>5 km2) across Asia and estimate their storage variations.
