Degradation Rate and Lifetime of Small Impact Craters on the Moon
AGU Advances, Volume 7, Issue 7, October 2026.Abstract Knowledge of crater degradation rates on the Moon is fundamental for dating individual craters, understanding material transport, and investigating crater equilibrium, with broader implications for water ice exploration, regolith evolution, and impact flux reconstruction.

Spatiotemporal Dynamics of Growing‐Season Plant‐Available Water in the Continental United States
Earth's Future, Volume 14, Issue 10, October 2026.Abstract Plant‐available water (PAW) is a primary regulator of plant growth, ecosystem productivity, and drought resilience, yet its spatial heterogeneity and long‐term response to hydrothermal changes remain poorly quantified at continental scales. Here, we quantify historical (2005–2015) and projected (2030–2100) changes in growing‐season PAW across ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract In paleomagnetism, records of paleosecular variation (PSV) on centennial timescales are often based on magnetic measurements from lava flows. However, samples from recent flows that cooled in known magnetic fields often fail to produce the expected paleomagnetic directions, and samples from the same flow often show large within‐ and between ...

Distal Rays and Secondary Craters of the Tycho Impact Event Revealed Through Deep Learning
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract The nature of secondary impact craters is a matter of ongoing debate, with important implications for understanding the impact cratering process, and for calibration of crater chronology. Rays generated by primary impact craters are characterized by secondary craters, providing identifiable terrains to study the size, morphology and clustering

Tracking Slow‐Moving Landslide Responses to the 2023 Kahramanmaraş Earthquake With InSAR
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.Abstract Strong earthquakes can have a dual impact on the slow‐moving landslide budget of a landscape by either triggering new actively deforming hillslopes or stabilizing existing ones. However, their regional‐scale influence on hillslope processes remains poorly understood because of limited observational coverage and the masking effects of long ...

Coseismic Shallow Landslide Distributions Reveal Patterns of Regolith Thickness in High Mountains
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.Abstract Earthquake‐triggered landslides are a major source of sediment mobilization in steep mountain landscapes, yet the controls that organize regional patterns of coseismic shallow failure remain incompletely understood. Because shallow landslides occur within regolith, their initiation and magnitude depend strongly on near‐surface material ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Classical satellite altimetry has limited sensitivity to seafloor topography at wavelengths shorter than about 150 km, leaving short‐wavelength structure poorly constrained away from ship tracks. The Surface Water and Ocean Topography (SWOT) mission improves gravity recovery at these scales.

DeepZoo: A cost‐effective and modular sampler for ecological studies in the deep ocean
Methods in Ecology and Evolution, Volume 17, Issue 10, Page 2895-2908, October 2026.Abstract Understanding the structure and dynamics of deep‐ocean communities requires effective sampling of pelagic organisms in near‐bottom waters. These dispersive organisms contribute to biodiversity, connectivity and ecosystem recovery. Yet, current sampling methods remain constrained by size, cost, and depth, leaving key questions unanswered in ...

The economic foundations of powersharing: Evidence from Africa
American Journal of Political Science, Volume 70, Issue 4, Page 1638-1652, October 2026.Abstract How—and with whom—do rulers share power? Existing research focuses on the strategic logic of powersharing. In this paper, we analyze its economic foundations. Powersharing is modeled as a subnational fiscal contract, in which rulers allocate political representation based on constituencies’ revenue potential. Empirically, we combine historical

Boreas, Volume 55, Issue 4, Page 1014-1031, October 2026.A detailed morphometric analysis of 200 cirques across the western Putorana Plateau, central Siberia, was undertaken to investigate cirque development, reconstruct glaciers and infer palaeoclimatic conditions. Cirques are amphitheatre‐shaped landforms with mean length and widths of 936 and 1000 m, respectively, indicating a mature glacial landscape ...
