Microstructural Controls on Geothermal Reservoir Host Rock Responses to Elevated Pressures and Temperatures

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Rock microstructure controls geothermal fluid flow within reservoirs hosted in active volcanic environments and as such it is necessary to constrain the microstructural evolution of rocks at elevated pressure and temperature conditions. Despite Andean geothermal systems hosting numerous high enthalpy geothermal plays, there remains a paucity ...

Instability of Fluid‐Mineral Equilibrium Under Non‐Hydrostatic Stress Investigated With Molecular Dynamics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Mechanical–chemical coupling governs the interaction between metamorphism and deformation and controls the long‐term stability of subsurface reservoirs. Deformation induces non‐hydrostatic stresses in minerals. However, the conditions for thermodynamic equilibrium between stressed solids and fluids remain debated.

Foredunes in Front of Secondary Dunes Exhibiting Strong Reduction Potential in Storm Wave Settings: A 2D Experimental and Numerical Study

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Coastal zones need further investigations of beach dune erosion to improve storm‐surge protection measures in light of climate change. This study presents a hybrid approach investigating the influence of coastal foredunes on storm‐induced secondary dune erosion.

Monitoring Coral Reef Metabolism Under Changing Oceans–Novel Insights From Seawater Stable Carbon Isotopes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Mounting environmental stressors are driving Caribbean reefs from coral to sponge and macroalgae dominance, necessitating a need for more nuanced metrics of reef metabolism under trophic transitions. Drawing upon four seasonally replicated field campaigns to Curaçao, we reveal highly variable net ecosystem productivity (−243 ± 69 C m−2 day−1 ...

Evidence for Long‐Term Coupling of Deep Ocean Carbon Storage and Global Climate Over the Past 4.5 Million Years

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Robust evidence indicates that late Pleistocene glacial‐interglacial climate cycles are linked to periodic, orbitally‐forced changes in the partitioning of CO2 between the deep ocean and atmosphere. The extent to which changes in deep ocean carbon storage are related to climate on longer timescales is less well understood.

Tracking via Coccolith Assemblages the East Asian Monsoon and Carbonate Production in the South China Sea During Termination II and Marine Isotope Stage 5e

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Coccolith assemblages from the last 158 kyr, encompassing Marine Isotope Stage (MIS) 5e (130–116 kyr) and preceding deglaciation (Termination II; T‐II), offer important insights about current and future climate changes. The South China Sea (SCS) represents a perfect area for reconstructing past East Asian Monsoon (EAM) dynamics thanks to its ...
