Real-Time characterisation of ocean transport

Problem Addressed

In critical situations—such as oil spills, container losses, pellet dispersion or maritime search and rescue operations—it is essential to understand, in real time, how water masses and drifting objects move. This requires Lagrangian models driven by modelled or observational current data.

What we do and how we do it

• We operate real-time Lagrangian models fed by modelled current and wind data, as well as observational data from the EUSKOOS observing network (HF radars).
• We integrate this information into operational systems capable of generating hourly and daily drift forecasts.
• We apply these tools to:
  • Maritime emergencies (pollutant spills, search and rescue).
  • Tracking of drifting objects and marine debris, such as plastic pellets or lost fishing gear.
  • Decision support for Maritime Rescue (SASEMAR) and local authorities.
• We validate model performance through drifter buoy campaigns to ensure reliability.
• We collaborate within international networks to keep these tools aligned with the state of the art in science and technology.

Key Benefits

• Real-time information to support maritime emergency response.
• Reduced environmental impacts through faster and more effective interventions.
• Predictions adapted to the complex coastal dynamics of the Bay of Biscay.
• Practical tools for authorities, rescue services and productive sectors.
• Strengthened positioning of AZTI as a reference centre in operational modelling applied to safety and environmental management.
