Seagrass meadows are one of the most important coastal habitats across the globe. In the Mediterranean Sea, Posidonia oceanica is the dominant endemic plant that affects physical, biogeochemical, and biological processes. The monitoring of the spatial distribution requires an update and accurate seagrass meadows delineation, i.e. meadow edge marking with a replicable method.

This study aims to present an approach to support the coastal marine habitat mapping, under the scheme of the Natura 2000 network using very high-resolution Earth observation data and to test if satellite images can be used for the mapping of the deep limits of seagrass meadows.

The authors state that their results prove that high-resolution satellite images can be used for coastal mapping and that the deep limits of the seagrass meadows can be identified even in large depths when the water column conditions allow.

It is stated that good knowledge of the site area is a prerequisite for ensuring highly accurate and precise results with low uncertainty and highlight that the WorldView constellation is a reliable satellite platform among the VHR satellite-based sensors, suitable for fine scale coastal habitat mapping.
