Ageostrophic Velocities of Curved Ocean Fronts

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Ageostrophic velocities at ocean fronts play a key role in ventilating the upper ocean. The overturning circulation driven by cross‐front ageostrophic flow is widely recognized as the major mechanism of vertical transport, but the role of along‐front ageostrophic velocities remains underrepresented in existing theory.

Paleoseismic Evidence of Recent Co‐Seismic Ruptures in Western Tierra del Fuego, Chile

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The Magallanes‐Fagnano fault (MFF) in Tierra del Fuego (TDF) is a major left‐lateral transform boundary between the South American and Scotia plates. While surface ruptures associated with the 1949 earthquakes have been documented in Argentina east of the Fagnano Lake, their extension to the west remained uncertain.

Uplift of the Transantarctic Mountains: Evidence for an Evolving and Long‐Lived Rayleigh‐Taylor Instability

Tectonics, Volume 45, Issue 8, August 2026.
Abstract Rayleigh‐Taylor instabilities within the upper mantle are investigated as a mechanism for the uplift of rift‐margin mountain ranges within the continents. Our focus is on the Transantarctic Mountains (TAM). These mountains form at the margin between East and West Antarctica and have been free from the effects of subduction for about 500 ...

Active Tectonics of the Eastern and Southern Alps ‐ Crustal Response to Deep Processes? A Review

Tectonics, Volume 45, Issue 8, August 2026.
Abstract Owing to the low N‐S convergence rates between Adria and Europe, crustal deformation rates in the Alps and its forelands are low. Active tectonics are, therefore, difficult to study, especially as non‐tectonic landscape forming processes can erase or modify the tectonic surface imprint. Large‐scale and dense seismological data recently offered

Architecture of the Patrimonio Fault System and the Miocene Post‐Orogenic Extension in Alpine Corsica (France)

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The exhumation of Alpine Corsica is the result of Oligocene‐Miocene lithospheric back‐arc extension in the wake of the eastward migration of Apenninic subduction. Although the geometry, kinematics and timing of ductile detachments are well constrained, the brittle extension leading to final exhumation of Alpine Corsica is less documented.

Spatial Dependence of High‐Frequency Ground Motion Along the Chilean Subduction Zone From Aftershock Sequences of the Mw 8.8 Maule and Mw 8.2 Iquique Earthquakes

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract The Chilean subduction zone is a highly active seismic region, producing megathrust earthquakes approximately every decade. We apply a stochastic approach to assess spatial variations in seismic wave characteristics along the Chilean trench using weak motion data.

Influence of Deep‐Sea Carbonate Sediments on the Long‐Term Durability of Carbon Storage From Ocean Alkalinity Enhancement

Global Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract Ocean Alkalinity Enhancement (OAE) is a marine carbon dioxide removal (CDR) strategy with a theoretical sequestration potential of several Gt CO2 ${\mathrm{C}\mathrm{O}}_{2}$ yr−1 ${\mathrm{y}\mathrm{r}}^{-1}$. The long‐term durability of OAE‐induced carbon storage depends on the persistence of the added alkalinity in the ocean, which is ...

Event Deposits Recorded Over the Past 800 kyr in IODP Hole U1433A (South China Sea): Implications of a Revised Methodology for Chronology and Paleoclimate Reconstruction

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Instantaneous event deposits such as turbidites, debrites, and slumps are common and frequently occur in marginal seas. These instantaneous deposits represent seconds to days in duration, and can therefore significantly impact age‐depth models and interpretation of paleoclimate history based on thick sedimentary sequences recovered in deep ...

Structurally‐Controlled Permeability Evolution and Mineralization in Geothermal Caprocks: The Fenice Capanne Mining District (Southern Tuscany, Italy)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The Neogene mineralized region of the Colline Metallifere in southern Tuscany (Italy) provides a natural laboratory to investigate feedback between fluid–rock interaction, structurally controlled fluid flow, and hydrothermal ore mineralization.
