ZEPHYRUS P&M research team has been surveying the Aveiro lagoon salt marshes with its drone Suzanne Daveau II, using a multispectral camera. ZP&M is mapping vegetation communities and monitoring coastal changes in both the Aveiro and Tagus salt marshes, in order to contribute to the assessment of the fate of mercury contaminants in sediments. This project is a collaboration with the Centre of Structural Chemistry at Técnico - ULisboa and University of Aveiro.
