Detection of Macroalgal Bloom from Sentinel−1 Imagery

Remote Sensing, 2023
The macroalgal bloom (MAB) is caused by brown algae forming a floating mat. Most of its parts stay below the water surface, unlike green algae; thus, its backscatter value becomes weaker in the synthetic aperture radar (SAR) images, such as Sentinel−1 ...
