Abstract
Frequent resuspension of sediments in the water column hampers photosynthesis in submerged aquatic vegetation due to decreased light, reduces gas exchange from sediment deposition and affects their anchoring ability. Remote sensing of light attenuation of the water column in form of diffuse attenuation coefficient of downwelling photosynthetically available radiation (KdPAR) provides a spatial perspective to study light attenuation of water column. This study aims to use Sentinel-2 derived KdPAR to characterize light variation and test its significance in relation to occurrence of eelgrass (Zostera marina) at Horsens and Roskilde fjords located in coastal waters of Denmark. Areas with maximum of KdPAR (mean > 75th percentile) coinciding with maximum and minimum variation (standard deviation >75th and
