Analysis of Turbulent Modeling for Free‐Surface Flows Using a Hybrid RANS‐LES Model and Particle‐Based Moving Particle Semi‐Implicit Method

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.
A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.

Mesoscale Circulation and Coral Community Disturbance at Isolated Reefs

open access: yesGlobal Change Biology Communications, Volume 1, Issue 1, March 2026.
The Loop Current is a seasonally and interannually dynamic mesoscale oceanographic feature in the Gulf of Mexico that strongly influences connectivity and environmental conditions across the region. We investigated the influence of Loop Current variability on coral reef disturbances at isolated reefs in the northwest Gulf, including coral disease ...

Potential Impacts of Climate Interventions on Marine Ecosystems

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Rising global temperatures pose significant risks to marine ecosystems, biodiversity, and fisheries. Recent comprehensive assessments suggest that large‐scale mitigation efforts to limit warming are falling short, and all feasible future climate projections, including those that represent optimistic emissions reductions, exceed the Paris ...
