Deep Sources of Recent Volcanism in Armenia Inferred From Ambient Noise Tomography

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract We perform Rayleigh wave ambient noise tomography to investigate crustal seismic velocity structure and sources of volcanism in Armenia. Armenia, a key part of the tectonically and volcanically active Caucasus‐Anatolia region, is actively being deformed by the ongoing Arabian‐Eurasian continental collision.

Geomagnetic Variability in a Post‐Superchron Geodynamo: Insights From the Deccan Traps

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Studying long‐term geomagnetic field behavior is crucial for understanding Earth's evolution, as field variability reflects processes in the planet's deep interior. One key question concerns the relationship between field strength and polarity reversal frequency, particularly during the Cretaceous Normal Superchron (CNS), a prolonged interval ...

Environmental Controls on the Cycling of Fe and Mn in Patagonian Fjord Systems

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Fjord sediments are important reservoirs and conduits of potentially bioavailable iron (Fe) and manganese (Mn). Both elements are critical to life, serving as key reactants in metabolic pathways, and play an important role in the reactivity and burial of organic carbon.
