Tracking Mediterranean marine litter through observation-grounded Lagrangian models
The Mediterranean's Southern Tyrrhenian and Northern Ligurian seas exhibited near-persistent floating marine macro-litter occurrence in 2024, with coastal deposition frequencies highest on Corsica, western Sardinia, and northern Tunisia. This data-driven Lagrangian framework, anchored by systematic shipboard surveys, gives decision-makers an observation-grounded tool for MSFD Descriptor 10 monitoring.

Hurricane Paths Shape Estuarine Flushing in Florida’s Multi-Inlet Systems
Two hurricanes. Two weeks apart. Opposite outcomes. That is the story emerging from our new modeling study of Florida's multi-inlet estuaries, where we found that storm track, not just storm strength, dictates how these systems flush. Hurricanes Helene and Milton hit the same region, yet their winds drove contrasting bay, ocean exchanges. Helene shifted from landward intrusion to oceanward flushing; Milton did the reverse. This is a clear demonstration that wind orientation relative to inlet geometry governs transport pathways.
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.

Hurricane Irma's Impact: Salinity Shifts in a Florida Estuarine Bay
Hurricane Irma's floodwaters did not simply wash through South Florida; they reshaped Biscayne Bay's salinity with measurable force. Using numerical simulations, we found canal discharge drove salinity shifts up to 20 psu, while rainfall alone contributed just 8 psu. Near shore, canals accounted for 90% of the change; offshore, rainfall dominated. Wind proved decisive, accelerating flushing within days under easterlies. This is empirical ocean intelligence, clarifying how extreme events redistribute freshwater.
