Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.Eighteen boreholes in Colombia's Tropical Andes reveal elevation‐controlled Critical Zone architecture. Four‐layer weathering profiles with thick saprolite (≤48 m) form at high elevations (>1,100 m) where dense fracturing enhances permeability. Low‐elevation boreholes lack saprolite despite high fracture density, demonstrating fracturing's dual role as

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.Rainfall‐induced landslides involving on Auckland Volcanic Field scoria cones are highly unusual, compared with widespread landsliding in the surrounding Auckland clay‐rich residual soils. Indeed, while Auckland can suffer from thousands of rainfall‐induced shallow landslides from severe storms at subdecadal timescales, these are usually limited to ...

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.The Rangitīkei Valley in the lower North Island of New Zealand contains flights of river terraces that are influenced by changes in sediment supply, stream power and base level associated with Quaternary climate events over the last ∼350 thousand years.

Diurnal Temperature Variability at Latitudinally Distinct Sites on the Moon
Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract The thermophysical environment of the Moon plays a crucial role for future exploration, resource utilization and also in understanding its geological evolution. While global‐scale surface temperature distributions have been reasonably well constrained through numerical modeling and orbiter observations, recent in situ measurements have ...

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Recently, possible exceptionally young mare volcanic glass beads were discovered in Chang'e‐5 (CE‐5) samples. Isotopic dating suggests an age of approximately 120 Ma, presenting new challenges to existing lunar thermal evolution models. Thus, our research focuses on the source region of Rima Mairan, a branch of Rima Sharp, and its surrounding ...

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

A Two‐Part Framework for Depth to Bedrock Prediction and Uncertainty Assessment in Sweden
European Journal of Soil Science, Volume 77, Issue 2, March–April 2026.ABSTRACT Accurate mapping of depth to bedrock (DTB) in complex post‐glacial landscapes is challenging due to high spatial variability and the prevalence of bedrock outcrops, which introduce “structural zeros” that violate standard regression modelling assumptions.

Pleistocene Smoothing and Resurfacing of Appalachian Ridgelines by Periglaciation
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Pleistocene cold periods created widespread periglacial conditions across mid‐latitudes, but isolating their geomorphic impact from modern climate, tectonics, and rock strength is challenging. We studied Appalachian (Eastern U.S.) ridgelines across a paleoclimate gradient, controlling for bedrock and structure, to test if colder periglacial ...

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Soil production, through bedrock weathering, regulates landscape evolution, biogeochemical cycles, and societal sustainability, yet quantifying soil production rates (SPRs) remains difficult due to limited tools. Here, we present a new framework for measuring SPRs based on uranium comminution ages and validate this approach at a deep granitic ...

Morphology of Antarctic Polygons and Implications for Polygon Evolution and Subsurface Ice Dynamics
Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 143-153, January/March 2026.ABSTRACT Polygonal terrain results from thermal contraction, is commonly found in periglacial environments, and serves as a valuable proxy for interpreting subsurface ice distribution and climate history on Earth and Mars. In this study, we investigate the morphology of polygons in Beacon Valley, Antarctica, to assess the relationship between polygon ...
