Field notes
The source notes describe radar readings as water speed inferred from radio waves reflected off waves, at roughly 300-metre spacing and one-minute intervals. The site also distinguishes hourly mean-spring-tide vectors in the Zeeschelde atlas from Zeebrugge atlas values updated every 20 minutes and averaged over the top 10 metres; forecast-model videos include that day's forecast wind.
