Protecting the coastal coastal marine ecosystem of Posidonia oceanica from Space using Sentinel-2

QUASAR SCIENCE RESOURCES, S.L., has mapped for the Ministerio de Transición Ecológica y Reto Demográfico the marine ecosystem of Posidonia oceanica meadows along the Spanish Mediterranean coast (and Balearic Islands) using Sentinel-2 satellite images from 2021, combined with large data sets processing techniques and AI algorithms. In addition, a pilot study has been carried out for the assessment of the temporal evolution of the extension of these meadows between 2017 and 2021.
