Transition of Glacial Regimes Recorded at IODP Site U1524 in the Ross Sea, Antarctica, Over the Last 800 Thousand Years

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract Reconstructing past interactions between the West Antarctic Ice Sheet (WAIS) and changing environmental conditions in the Ross Sea region can help determine long‐term WAIS stability. Existing sedimentary records reveal changes to oceanography, sea ice and ice sheet extent over the glacial‐interglacial cycles of the last ∼800 kyr.

Active Normal Fault Segmentation and Linkage in the Umbria‐Marche Apennines (Italy): Insights From 3D Structural Modeling

open access: yesTectonics, Volume 45, Issue 10, October 2026.
Abstract Normal‐fault growth, segmentation, and their relationships with crustal inheritance and rheological layering are investigated in a post‐thrusting setting of the southern sector of the Northern Apennines. We integrate 3D modeling with gravity, thermal, and seismological constraints to reconstruct the geometry and evolution of the main normal ...

Episodic Arc Behavior in an Accretionary Orogen: Insights From the New England Orogen, Eastern Australia

open access: yesTectonics, Volume 45, Issue 10, October 2026.
Abstract Detrital zircon U–Pb geochronology from Triassic–Jurassic basins in the New England Orogen (NEO) constrains sediment provenance and episodic continental arc evolution along the eastern Gondwanan margin. Dominant zircon clusters at 270–230 Ma and 340–300 Ma in these basins were likely sourced from contemporaneous magmatism in the NEO ...

Quantifying Groundwater–Surface Water Exchange on a River Island: A Comparative Analysis of Direct and Indirect Methods

open access: yesWater Resources Research, Volume 62, Issue 10, October 2026.
Abstract Groundwater–surface water exchange is a key hydrological process that governs river water quality and aquatic ecosystems. However, the quantification of such exchange remains uncertain, especially within river island aquifers where exchange processes are highly heterogeneous.
