Absorption by pure water
Absorption very strong in red and NIR
Small change in water dept = detectable
difference in RS signal in red and NIR
High accuracy in depth estimation
10 cm depth variations easily detectable10 cm depth variations easily detectable

Impact of atmospheric correction
Impact of glint and atmospheric correction
Bright sand in shallow water Deep water
Impact of wind?
SDB for fish stock recovery
Some former bays potentially
very good fish spawning sites
Fish likes vegetation, but not
when it is reaching the surface
With remote sensing we
should be able to recognise
suitable areas
Validation tool
Thank you for your attention!
