Blue and black fibres dominated every seawater sample collected in Saint John Harbour, and 94% of zooplankton taxa had ingested microlitter. In Arctic oil-spill emergencies, the margin for error is measured in hours and ecological cost.

Saint John Harbour: Establishing a Baseline for Microplastic Levels
Blue and black fibres dominated every seawater sample collected in Saint John Harbour, and 94% of zooplankton taxa had ingested microlitter. That finding, from a multi-year survey by our researchers, establishes a critical baseline for microplastic levels in the Bay of Fundy. Notably, larval fish and *Calanus* copepods showed the highest encounter rates. This is empirical, local data, the kind needed to monitor change and assess ecological risk.
Optimizing Arctic Oil Spill Response with Integrated Data and Simulation
In Arctic oil-spill emergencies, the margin for error is measured in hours and ecological cost. A hierarchically hybrid scheduling framework, coupling decision tiers from resource call-ups to on-site adjustments, directly confronts this complexity. The Barents Sea case study proves the model's mettle: a balanced solution achieving a 25.1-hour response time with an 84.6% recovery rate, cutting composite performance loss by over 59% against static planning. This is the integrated data ecosystem operational, not theoretical.
Halogenated Flame Retardants: Tracking Distribution and Risk in Korean Coastal Waters
Along the Korean coast, the chemical fingerprints of flame retardants are changing. New measurements from sediment and bivalves at 50 locations confirm a clear shift: while legacy PBDEs and HBCDDs persist, alternatives like decabromodiphenyl ethane are taking their place, particularly near industrial hubs. This transition is not without consequence. BDE 47 shows a real potential to accumulate in biota, and localized hotspots of BDE 209 demand attention.
