Bay of Bourgneuf intertidal seagrass

Thanks to an ESA-funded project and data from the Copernicus Sentinel-2 mission, researchers have revealed seasonal variations in intertidal seagrass across Western Europe and North Africa. As a key indicator of biodiversity, these new findings offer valuable insights for the conservation and restoration of these vital ecosystems.

The two Sentinel-2 images shown here illustrate changes in intertidal seagrass cover in the Bay of Bourgneuf, located north of the Bay of Biscay, off the western coast of France. The image on the left, from April 2021, shows sparse intertidal seagrass, while the image on the right, from September 2021, reveals abundant growth.
