Fe–Mn Crust δ98Mo Decline Records Tectonic Forcing on Marine Oxide Sink Reduction During the Early Eocene–Early Oligocene

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract S, Tl, and W isotope records document pronounced early Eocene shifts in marine redox, yet the absence of a Mo isotope record obscures its progression. Here, we present ∼80 Myr Mo–Os–Be–Nd isotope profiles from a Northwest Pacific hydrogenetic Fe–Mn crust, revealing a systematic δ98Mo decline from −0.24‰ (early Eocene) to −0.83‰ (early ...

Large‐Scale Hydrogen Storage: Surface and Subsurface Challenges

ChemBioEng Reviews, Volume 13, Issue 2, April 2026.
This review examines underground hydrogen storage with emphasis on the interaction between surface facilities and subsurface reservoirs. Variable renewable hydrogen requires compression, buffering, and purification before injection, while subsurface processes influence wellhead pressure, temperature, and composition.

Event‐driven shifts in river and reservoir sediment sources: Cottonwood River and John Redmond Reservoir, USA

Earth Surface Processes and Landforms, Volume 51, Issue 4, April 2026.
In‐channel flow events are dominated by streambank sediment (50%) whereas downstream lakebed deposits are dominated by cropland sources (40%). This shift in sediment provenance is event‐driven: during infrequent, out‐of‐bank flood events, vast quantities of floodplain cropland soil are mobilized in exceedance of the river's bank‐dominated internal load.

Observed Hydroclimatic Trends and Their Implications Over Water‐Cycle Dynamics in Montérégie, Southern Quebec, Canada

Global Challenges, Volume 10, Issue 4, April 2026.
In this study, we quantified the changes in different hydroclimatic parameters and evaluated their impacts on the groundwater resources across Montérégie. Using the GR4J+CemaNeige model, and multi‐decadal hydroclimatic records, the study shows the watershed's variability and identifies seasons and land cover scenarios where groundwater recharge ...

Development and Application of a Simplified Method for Preliminary Assessment of Enhanced Oil Recovery and CO2 Geological Storage in Petroleum Reservoirs

Greenhouse Gases: Science and Technology, Volume 16, Issue 2, Page 238-252, April 2026.
ABSTRACT Geologic carbon storage in depleted oil and gas reservoirs is a key CO2 mitigation strategy, utilizing existing infrastructure such as injection wells and pipelines, while capitalizing on well‐characterized subsurface properties. This article introduces a versatile methodology designed to estimate critical parameters, including the number of ...
