The Laboratory for Optical Biogeochemistry and Remote Sensing from Stirling University and the Remote Sensing and GIS Lab of Applied Physic Department of University of Vigo, went on a fieldwork campaign to characterize the biogeooptical parameters of the complex waters of the Ria de Vigo as part of the the validation of Copernicus EU Sentinel-2 and -3 data.
Check out some of the fieldwork campaign photos because they didn't only manage to spot a harmful algae bloom but also some dolphins!
