Anisotropic Melt Inclusions as a Confounding Signal for Ice‐Penetrating Radar Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Ice‐penetrating radar is a powerful geophysical tool for understanding the subsurfaces of Earth, Mars, and icy moons. Radar reflectivity, attenuation, and birefringence are used to infer subsurface hydrology, englacial temperature, water content, and crystal orientation fabric.

Going Deeper With Deep Learning: Automatically Tracing Internal Reflection Horizons in Ice Sheets—Methodology and Benchmark Data Set

open access: yesJournal of Geophysical Research: Machine Learning and Computation
Mapping the internal stratigraphy of ice sheets serves a variety of glaciological applications, from the study of past ice flows to current distribution of surface mass balance and melting to contemporary ice dynamics, all of which are crucial for ...

Image-radargram analysis based on generalized Hough transform: experimental cases

open access: yesJournal of Geophysics and Engineering, 2012
This paper presents an algorithm based on the generalized Hough transform (GHT) to enhance geological structures in a 2D profile image constructed from ground-penetrating radar data. The proposed algorithm is applied over an edge representation image of the radargram; its local application (in Windows) allows us to identify structures and to obtain a ...

Dual‐Functional Additive Regulating Zn2+ Solvation Structure and (002) Plane‐Oriented Deposition for Dendrite‐Free Zn Anodes

open access: yesAdvanced Functional Materials, Volume 36, Issue 19, 5 March 2026.
Sulfosalicylic acid (SSA) is introduced as a bifunctional additive for Aqueous zinc‐ion batteries. SSA reconstructs the solvation structure of Zn2+ through the synergistic effects of its multiple functional groups, suppressing side reactions while selectively promoting Zn (002) deposition to prevent dendrite formation.

A Deep Learning Architecture for Semantic Segmentation of Radar Sounder Data

open access: yes, 2021
During the last decades, radar sounders provided direct measurements (radargrams) of the Earth’s polar caps’ subsurface. Radargrams are of critical importance for a better understanding of glaciologic structures and processes of the ice sheet in the ...

Preservation of Historically and Scientifically Important Geospatial Data From Venus

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract A large volume of scientifically and historically important data from the early exploration of Venus is not widely available to researchers. Our work is focused on ameliorating this problem with the archival of geospatial data including radar, topography, and radiometry.

Enhanced Resolution of Martian Polar Stratigraphy via Structure Enhancement Denoising and Sparse Deterministic Deconvolution of SHARAD Data

open access: yesRemote Sensing
The Martian North Polar Layered Deposits (NPLD) are a thick sequence of ice and dust layers that serve as a primary archive of the planet’s recent climate history.

Automated detection and characterization of diffraction curves in WISDOM/ExoMars radargrams [PDF]

open access: yes
IntroductionWISDOM (Water Ice Subsurface Deposits Observation on Mars) will be the Ground Penetrating Radar of the Rosalind Franklin rover of the ExoMars 2022 mission. This rover will be the first able to collect samples down to 2 m in the Martian subsurface, and analyse them in search of potential traces of life [1].

Revealing the Internal Structure of Mars‐Analog Glaciers From Drone‐Based Radar Sounding

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Martian debris‐covered glaciers (DCGs) contain large quantities of water ice beneath a protective layer of rock and dust. Properties of the overlying regolith such as density and depth to ice are critical parameters for guiding in situ resource utilization (ISRU) of water and coring missions targeting potential habitats.

IceAnatomy: a benchmark dataset and methodology for automatic ice boundary extraction from radio-echo sounding data [PDF]

open access: yesThe Cryosphere
The measurement of ice thickness is of great importance for the accurate estimation of glacier volume and the delineation of bedrock topography. In particular, this is a crucial factor in forecasting the future evolution of glaciers in the context of a ...
