Air Contamination and Mass Fractionation Correction in Groundwater From a Hydrocarbon System

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Noble gases are valuable geochemical tracers for investigating subsurface fluid origins and migration because of their chemical inertness and source‐specific isotopic ratios. However, subsurface water samples often show noble gas patterns that differ from air‐saturated water references, with excesses or depletions that complicate ...

Genetic Diversity and Population Structure of Squalus cf. mitsukurii (Chondrichthyes: Squalidae) Revealed by ddRAD Sequencing

Animal Genetics, Volume 57, Issue 2, April 2026.
ABSTRACT Assessing genetic structure across ocean basins is essential to understand connectivity and guide conservation in data‐deficient open‐water sharks. In this study, we examined the population genomics of Squalus cf. mitsukurii by analyzing tissue samples collected from two distant regions: California, USA (Pacific Ocean) and Pernambuco, Brazil ...

Late Eocene to Early Oligocene (36–26 Ma) Rock Magnetism and Magnetostratigraphy of IODP Site U1553, Southwestern Pacific: Defying the Challenges of Carbonate Dilution and Reductive Diagenesis

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The late Eocene to early Oligocene is an intriguing Paleogene period in which the Earth climate state changed from Warmhouse to Coolhouse. Accurate age models are essential for investigating these climate transitions. The southwestern Pacific International Ocean Discovery Program (IODP) Site U1553, with its almost complete succession of the ...

Encapsulating Textiles with Dynamic Covalent Networks for Sustainable and Efficient Oil Spill Cleanup

Advanced Science, Volume 13, Issue 13, 3 March 2026.
By encapsulating industrially relevant fabrics with dynamic imine networks, we show that the resulting composites exhibit exceptional oil absorbtion capability and chemical recyclability. It is poised for sustainable oil spill cleanup. ABSTRACT The development of high‐performance sorbents for oil spill remediation is highly desirable, which now calls ...

Fluid Flow Simulation for Predicting Bottomhole Pressure That Considers Wellbore Storage Effects Under Shut-In Conditions in Deepwater Drilling

Journal of Marine Science and Engineering
Under shut-in conditions in deepwater drilling, the gas invading the bottomhole ascends along the wellbore and accumulates at the wellhead, forming a high-pressure trap, challenging wellbore pressure prediction and control.

Saving the Planet, Saving the Team, and Shouting Down the Messenger: The Relationships Among Narcissism Subtypes and Misreporting of Emissions

Corporate Social Responsibility and Environmental Management, Volume 33, Issue 2, Page 2413-2431, March 2026.
ABSTRACT This study examines how three subtypes of narcissism—communal, antagonistic, and collective—relate to sustainability team members' willingness to misreport greenhouse gas (GHG) emissions. Using survey‐based online experiments with experienced professionals from the United States and United Kingdom, we assess whether narcissistic traits predict
