Dynamic Coastline Modeling Improves Oil Spill Risk Assessment.
A finite shoreline cannot absorb oil indefinitely, yet that is the static assumption most spill models rely on. This study replaces that flawed premise with a dynamic adsorption-desorption mechanism, integrating substrate-specific retention and release into the SCHISM model. The result is a rise-then-fall evolution of stranded oil, not a static partition. Applied to the Zhoushan Archipelago, it reshapes risk zoning by revealing how tidal flats trap while gravelly shores permeate.
Fjord Jellyfish Reveal Unexpected Population Structure Despite Wide Dispersal
In a Norwegian fjord, jellyfish are rewriting the rules of marine connectivity. Genetic analysis of *Aurelia aurita* reveals that benthic polyps act as a persistent reservoir of diversity, while their pelagic medusae are transient, environmentally filtered subsets. Drift simulations predicted homogenized mixing, yet field data shows heterogeneous genetic structure. Dispersal potential alone cannot explain this. Life-stage complexity and local demographics matter.

Microplastic Pollution Assessed Across Key International Shipping Routes
Aboard the research vessel *Jaywun*, 100 surface-water samples now trace a microplastic story across the Atlantic, Mediterranean, Red Sea, and Arabian Gulf. Concentrations swung from 4 to 290 particles per liter, with polyester and PET dominating the mix. The Arabian Sea carried the heaviest load, while the Strait of Gibraltar surprised with a localized peak.
