A Hydrogeophysical Survey Utilising the sTEM and sTEMprofiler Systems: Transient Electromagnetic Data and Resistivity Models

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
We present a transient electromagnetic dataset from northwestern Denmark acquired with the novel sTEMprofiler system, mapping buried Quaternary valleys. The open dataset, including raw data and resistivity models, enables benchmarking of inversion methods and integration into geological and hydrological studies. ABSTRACT Transient electromagnetic (TEM)

Velocity estimation in GPR data based on diffraction analysis: Methodology and application to Antarctic firn

Near Surface Geophysics, Volume 24, Issue 2, Page 170-186, April 2026.
Abstract This study presents a methodological framework for estimating electromagnetic wave velocities in ground‐penetrating radar (GPR) data based exclusively on the analysis of diffractions. The approach integrates diffraction separation using the plane wave destruction algorithm and subsequent velocity refinement through the residual diffraction ...

Rates of Sea‐Level Rise Are Highly Sensitive to Ice Viscosity Parameters in Model Benchmarks

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Glacier flow plays a major role in current and future rates of globally averaged sea‐level rise. The viscosity of glacial ice, controlling the rate of flow, decreases as stress increases and is highly sensitive to the value of the stress exponent, n $n$, in the constitutive equation for viscous flow.

Mechanisms of Surface Meltwater Ponding and Drainage on the Greenland Ice Sheet Revealed Using SkySat Imagery and Deep Learning

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surface meltwater impacts Greenland Ice Sheet mass balance indirectly by reducing albedo and promoting hydrofracture. However, fully understanding both processes requires accurate mapping of small‐scale features such as ponds, channels, and moulins that govern meltwater formation and drainage. Here we investigate surface water dynamics at high

Cryogenian Glacial Erosion and Tectonics as Agents of Crustal Recycling

Terra Nova, Volume 38, Issue 2, Page 87-96, April 2026.
ABSTRACT Zircon preserves evidence of recycling processes that link surface environments to the mantle. Combined δ18O‐εHf in zircon fingerprints magmatic sources and tracks how crustal material is reworked over time. We apply statistical analyses to a global compilation that apparently resolves shifts in zircon U–Pb, δ18O, and Lu‐Hf data spanning the ...
