Abstract

Finding an accurate and simple methodology to map the deep-sea macroalgae in the West Channel and West Brittany zones will be of high interest to evaluate and survey the ecological and economical diversity of the seabed. Nowadays, only emerged or shallow-water macroalgae can be efficiently monitored by passive telcdection techniques based on the spectral analysis of their reflectance, whereas the deep-sea macroalgae are shaded by the water surface. This has led us to propose an in situ monitoring of the seabed using an active spectral methodology based on fluorescence imaging.
