The Magnetic Signature of Shear Zones in Marbles and Experimental Simulations

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
This dataset explores how strain, microstructure, texture and magnetic susceptibility interact in natural and experimental shear zones. It includes data from low‐ and high‐temperature marble shear zones and analogue experiments simulating different deformation regimes.

A Zonal‐Meridional Projection Method for Quantifying Global Land‐Ocean Moisture Transport

International Journal of Climatology, Volume 46, Issue 12, October 2026.
We present a physically consistent and computationally efficient method to quantify global coastal moisture transport by projecting vertically integrated moisture flux onto signed land–ocean boundary segments. The signed projection naturally distinguishes ocean‐to‐land inflow and land‐to‐ocean outflow without explicit directional classification ...

A novel integrated circular radiography (ICRAD) phantom for evaluating non‐uniform image quality metrics in radiography

Medical Physics, Volume 53, Issue 10, October 2026.
Abstract Background Anode heel effects have been shown to cause a non‐uniform distribution of X‐ray photon fluence, and anode angle could cause focal spot size variations across field. However, no previous study has investigated their effects on image quality metrics in radiography.

Resource competition between buoyancy‐regulating and sinking phytoplankton species along a stratified water column

Oikos, Volume 2026, Issue 10, October 2026.
In temperate lakes, plankton dynamics are closely linked to seasonal shifts in water stratification, following air temperature. The onset of summer stratification typically coincides with the formation of an algal spring bloom in the well‐mixed surface layer (epilimnion).

Electrical Resistivity Tomography for the 2D and 3D Investigation of Pingos and Permafrost Mounds in Northern Canada's Mountain and Coastland Areas

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 804-829, October/December 2026.
ABSTRACT Pingos and related permafrost mounds are widespread periglacial landforms in Arctic environments that are ice‐rich on the one hand and contain taliks on the other, making them vulnerable to climate change. So far, the interior, geophysical characteristics, and distribution of ground ice within these dome‐ or cone‐shaped features have not been ...
