Extremely Weak Geomagnetic Field Following Permo‐Carboniferous Reverse Superchron and Its Geological Implications

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Superchrons represent critical phases in geomagnetic field evolution, offering insights into Earth's distinct internal states. However, the lack of research on how the longest Phanerozoic superchron (Permo‐Carboniferous Reverse Superchron, PCRS, ∼318–263 Ma) terminated limits our understanding of the geodynamic processes and the interaction ...

Mesoscale Induced Vertical Fluxes Over the Iceland‐Faroe Ridge

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Mesoscale eddies play a crucial role in ocean dynamics, yet their impact on vertical heat fluxes over topographic features remains poorly understood. This study investigates the Iceland‐Faroe Ridge (IFR), a key boundary between the North Atlantic and Nordic Seas, southeast of Iceland.

Direct Ocean Tidal Current Measurements From Space: Enhanced Interpretation of Sentinel‐1 Doppler Shift Signals

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Advances in Sentinel‐1 Doppler processing have continued to unlock deeper understanding of surface current dynamics. With future missions emphasizing total surface currents observations, the resolving of processes will grow, including tidal currents.

The Santorini 2024–2025 Volcano‐Tectonic Sequence: Constraining the Initial Phase of the Intra‐Caldera Unrest

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract After less than 14 years from the previous 2011–2012 unrest, the Santorini volcano entered a new unrest phase, involving intra‐caldera deformation since July 2024 and microseismicity mainly after mid‐September 2024. We examine the first phase of this unrest, identified by GNSS and Synthetic Aperture Radar Interferometry data as an almost ...
