Drivers of Dissolved Thorium Isotope Distributions Along the Adélie Land Margin, East Antarctica: The Roles of Reversible Scavenging, Conservative Transport, and Lithogenic Supply

Global Biogeochemical Cycles, Volume 40, Issue 9, September 2026.
Abstract In this study, we present a mix of full‐depth profiles and near‐bottom observations of dissolved 230Th and 232Th from the Adélie Land margin in East Antarctica, a key site of Antarctic Bottom Water (AABW) formation. We show that the distribution of dissolved Th isotopes in this region is governed by a combination of reversible scavenging ...

Detection of Interannual and Fine‐Scale Plate Coupling Variations Using Intraplate Earthquakes and Geodetic Data: Application to the Tohoku‐Oki Plate Boundary

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We propose a method to infer detailed spatiotemporal variations in interplate coupling by integrating geodetic and seismic data. It examines whether focal mechanisms of intraplate earthquakes occurring near the plate interface align with the stressing rates caused by a geodetically derived slip‐deficit rate model, evaluating deviations from a ...

Reconciling Coupled Thermal‐Water Evolution Models of Earth With Observations Through Variable Regassing Efficiency

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Reconciling Earth's thermal evolution with geochemical observations remains a fundamental challenge, as parameterized convection models typically predict high present‐day Urey ratios inconsistent with geochemical estimates. Previous studies propose that if mantle water concentration varies inversely to mantle temperature, it would weaken the ...

Inception and Plate Evolution of the Lau Back‐Arc Basin From Plate Boundary Refinements

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Back‐arc basins are important settings for crustal growth that form in response to both near and far‐field tectonic influences. To better understand the processes that control back‐arc basin initiation and evolution, we present a refined model of the kinematics of opening of the Lau Basin, embedded in a global plate model.

Infragravity Waves Across a Steep‐Sloping Rough Rocky Seabed on the Inner Shelf

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Observations of infragravity (IG) waves were conducted from June to October 2023 along the rocky shores off China Rock, CA, on the inner shelf at depths of 8–13 m. The study examines inner‐shelf IG wave dynamics over rough, steep rocky shores and compares them with those over smoother, gentler sandy shores and coral reefs. IG energy correlated
