Porous and Permeable Crystalline Basement: Evidence for Large‐Scale Hydraulic Connectivity at Kivetty, Finland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Porosity and permeability in crystalline shield basement are commonly assumed to be low, yet some fault zones sustain fluid circulation over kilometer scales. Here we quantify multiscale fault‐zone connectivity at Kivetty, central Finland, by integrating legacy deep‐borehole data, including packer tests, downhole logs, and a long‐term multi ...

Submarine Landslides Could Cause Wide‐Spread Tsunami Impact in the East Sea (Sea of Japan)

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The East Sea (Sea of Japan) is a seismically active back‐arc basin with a history of devastating tsunamis, yet regional hazard assessments and mitigation planning often overlook the tsunamigenic potential of submarine landslides. This study investigates the tsunami impact of large‐scale mass failures along the southwest (SW) margin of the East

First Direct Observations of Dilute Antarctic Turbidity Currents Associated With Dense Water Overflows

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Turbidity currents are increasingly recognised as a key mechanism for transporting sediment into the deep ocean, yet their structure, behavior, and long‐term impact in Antarctic submarine canyons remain poorly understood owing to a lack of direct observations.

Untangling Dynamic Drivers of Salt Marsh Migration

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Coastal marsh transgression into upland ecosystems is driven by complex hydrological processes, stressing vegetation through root‐zone salinization and hypoxia, but interacting roles of these stressors remains poorly understood. We use high‐resolution field observations at six sites along the Delmarva Peninsula, USA, to better understand how ...

Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 5, Page 1255-1268, September 2026.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...
