Multidisciplinary Investigation of Healy Submarine Volcano (Kermadec Arc, New Zealand) Using AUV and Submersible Data: Structural Control on Magmatic and Hydrothermal Processes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract We present a comprehensive multidisciplinary investigation of the Healy submarine volcano in the southern Kermadec arc, northeast of New Zealand. We show the first results of sidescan‐sonar data collected at a submarine arc volcano by an Autonomous Underwater Vehicle (AUV).

Response of the Nitrogen Isotopic Composition of Planktic Foraminifer Tissue to Surface Ocean Nutrient Cycling: A Case Study in the Northern South China Sea

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract This study presents data on geographically small‐scale patterns of nitrogen (N) isotope signals (δ15N) within the northern South China Sea (SCS) imprinted on planktic foraminifers (PF). PF from net tows on the shelf, continental slope, and in pelagic waters from summer 2019 were analyzed for δ15N.

Intrusive Magmatism, Plate Stresses, and the Cause of Orthogonal Versus Oblique Spreading Mid‐Ocean Ridges

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The origin of orthogonally spreading ridge segments separated by oceanic transform faults, versus obliquely spreading ridge segments without transform faults (TFs), is a long‐standing enigma of plate tectonics. We address this problem using three‐dimensional (3D) geodynamic models that simulate axial magmatic intrusions along two ridge ...

The Seismic Signature of the Atlantis Massif Oceanic Detachment Fault Determined From Crystallographic Preferred Orientation and Microstructure

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract At slow‐spreading mid‐ocean ridges large scale detachment faults partly accommodate the spreading process. The mafic and ultramafic rocks at the ridges are infiltrated by water and change their mineralogy. Subsequently or contemporaneously to these reactions, detachment faulting takes place.

OBS Data Mining Reveals Seismic Structure and Dynamics of the Oceanic Blanco Transform Fault, Northeast Pacific

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Deformation along oceanic transform faults is partitioned between seismic and aseismic slip, controlled by lithology, thermal structure, and fluid circulation. We analyze one year of data from a 54‐station ocean bottom seismometer network deployed across the Blanco Transform Fault (BTF), Northeast Pacific.
