Measured
Surface currents from Rijkswaterstaat's HF radar, which reads the speed of the water from radio waves reflected off the waves, roughly every 300 m and every minute.
Model
Rijkswaterstaat's operational forecast models (SCALWEST, OSR, DCSM-FM) as published in the open RWsOS viewer. They compute the current on a fine grid every few minutes.
Atlas
The Stroomatlas Zeeschelde by Flanders Hydraulics Research (hourly vectors for a mean spring tide from the SCALDIS model) and the Stroomatlas Zeebrugge 2024 (every 20 minutes, mean of the top 10 m), interpolated in time and space.
AIS
Ship positions broadcast by every seagoing vessel, collected over 24 hours through aisstream.io and drawn as tracks, swing circles and a distance-time diagram.

Each video is labelled as measured, model or atlas. Atlas videos show average astronomical tides; model videos are forecasts for that specific day, including the forecast wind. Not for navigation.
