Periglacial Vegetation‐Banked Terraces: A Global Survey

Permafrost and Periglacial Processes, Volume 36, Issue 4, Page 715-738, October/December 2025.
ABSTRACT Periglacial vegetation‐banked terraces (VBTs) are roughly parallel, step‐like landforms with bare treads and vegetated risers, where tread length (across‐slope) markedly exceeds tread width (downslope). Many follow the contour, but others dip off‐contour at angles of up to 40°.

Regional Ice‐Depth and Thickness in Phlegra Montes, Mars From Radar Characterization of Glacial Landsystems Using SHARAD

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Morphological analyses of Viscous Flow Features (VFFs) in the mid‐latitude regions of Mars have led to the hypothesis that these landforms are equivalent to debris‐covered glaciers. Phlegra Montes is a 1400‐km‐long mountain range in the northern mid‐latitudes that spans from 30° to 50°N, where there is an abundance of glacial landsystems ...

Using Venus, Earth, and Mars to Understand Exoplanet Volatile and Climate Evolution

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Venus, Earth, and Mars exhibit a wide range of interactions between their deep interiors, surfaces, lower and upper atmospheres, and the Sun, with commensurate variations in the nature of their atmospheres and evolution of their volatiles. By examining these worlds' characteristics and behavior, we can gain some understanding of the breadth of

Subtle relict channels associated with large dolines in an area formerly beneath the Laurentide Ice Sheet, northern Ohio, USA

Boreas, Volume 54, Issue 4, Page 567-589, October 2025.
Low‐relief dry channels appear out of place across a glaciated karst landscape in northern Ohio. Channels are only a few metres deep cut into limestone and draped with a veneer of till. Several hypotheses are proposed for explaining the channels. Low‐relief dry channels are observed across the Bellevue‐Castalia Karst Plain of north‐central Ohio, USA ...

On the Crustal Architecture of the Terrestrial Planets

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Understanding the structure and composition of planetary crusts is fundamental for unraveling the diverse geologic pathways of rocky bodies in the solar system. In recent years, geophysical missions have shed light on the crustal architecture of the Moon and Mars.

Enhanced Seismic Backscattering for Lava Tube Detection

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract Lava tubes, a common volcanic feature on terrestrial planets, offer critical insights into lava flow processes and may serve as future potential habitats for space crews and other facilities on the Moon and Mars. Seismic detection of these features is challenging as the irregular morphology and rough cave ceilings and walls generate complex ...

Topographic Stress as a Mechanical Weathering Mechanism on Titan

Journal of Geophysical Research: Planets, Volume 130, Issue 8, August 2025.
Abstract Titan is unique among icy moons for its active surface processes and extensive erosional features. The presence of coarse sediment suggests that mechanical weathering breaks down Titan's surface material, but the exact processes of mechanical weathering are unknown.

The origin, evolution and life cycle of rock art shelters in the Kimberley Basin of NW Australia

Earth Surface Processes and Landforms, Volume 50, Issue 9, July 2025.
Sandstone rock shelters hosting abundant rock art in northwestern Australia evolve by undermining through recession of a weak layer, leading to progressive enlargement by bedding slab falls from the ceiling, creating new surfaces for rock paintings in the process. Eventually, continued undermining due to ongoing failure of the lower weak layer leads to

A Burial History of the Sedimentary Succession Preserved in Aeolis Mons, as Recorded by Fracture Networks at Maria Gordon Notch, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract Fractures in sedimentary rocks preserved within Gale crater record the deformational and burial history of the sediment infill. Fracture geometries and morphology can be used to time other geologic events, such as: compaction, diagenesis, fluid migration, geochemistry, and broader tectonic stresses within a basin.

Characterizing Fractured Zones in Urban Karst Geology Using Leaky Surface Waves From Distributed Acoustic Sensing

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Urban karst geology poses significant geohazard risks, most notably sinkholes and surface depression stemming from soluble and fractured bedrock that is prone to dissolution and collapse. However, mapping and characterizing these hazards using traditional geophysical surveys in cities is challenging due to dense infrastructure and high levels ...
