Quantifying the Surface Deformation of Pingos on the Alaskan North Slope Using Interferometric Synthetic Aperture Radar (InSAR)

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 682-691, October/December 2026.
ABSTRACT Pingos are large mounds with cores formed of intrusive ice that form in periglacial landscapes. These ice structures can form in regions of discontinuous permafrost, commonly as hydraulic or open‐system pingos, or in locations of continuous permafrost, commonly as hydrostatic or closed‐system pingos.

Ground Penetrating Radar Observations of Subsurface Structures From the Makgadikgadi Pans (Botswana): A Terrestrial Analogue of Martian Playa Lakes

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Playa lakes are considered promising landing sites on Mars because of their strong astrobiological potential. Therefore, sediments and buried structures in terrestrial playa lakes have become the focus of numerous analogue studies. The inclusion of ground penetrating radar (GPR) in the payloads of Martian missions has opened new avenues for ...

Towards the CNN-based detection of disturbing objects in multi-channel GPR data

, 2022
A Ground Penetrating Radar (GPR) is an active sensor system, which enables the detection of buried objects interacting with the radar signal. Detectable objects can be of man-made (e.g. pipelines) or natural (e.g. stones) origin.

A Gaussian Process Regression Framework for Slant Ionospheric Delay Interpolation and Uncertainty Quantification With Applications to PPP‐RTK

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Reliable slant ionospheric information is crucial for Precise Point Positioning Real‐time Kinematic (PPP‐RTK), yet its correction in low‐latitude regions remains difficult because of ionospheric variability, observable anomalies, and insufficiently reliable uncertainty characterization.

Ground Penetrating Radar (GPR) for bridge inspection

Bridge inspection plays a crucial role in providing bridge operators with an overview of their infrastructure’s current condition, enabling them to extend their service life. This is even more important since a significant number of bridges were constructed after World War II with few comprehensive documents regarding their construction, for example ...

Mapping Glacier Bed Topography in Crevassed Regions: A New Passive Seismic Reflection Method Applied to Isunnguata Sermia, West Greenland

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Glacier bed topography is crucial for modeling ice mass loss. However, heavily crevassed regions are challenging to survey using conventional methods, leading to data gaps. We establish a passive seismic approach exploiting naturally occurring crevassing events recorded with a dense seismic array to image the ice–bed interface without spatial ...

First Empirical Assessment of Ice Content From a Himalayan Rock Glacier

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Climate warming and degradation of glaciers and permafrost in High Mountain Asia is threatening the sustainability of the region's natural “water towers” and allied ecosystems and infrastructure. Approximately 25,000 Himalayan rock glaciers exist and, being more resilient to climatic change than glaciers, they represent important freshwater ...
