The Posidonia oceanica Atlas has involved exhaustive labor and field work that has allowed us to identify marine habitats in the Balearic Islands through different techniques, including Side Scan Sonar or the interpretation of satellite images. The final result of this project is a cartography with a higher level of detail of Posidonia oceanica on the seabed of the Balearic Islands. The last phase of this project has involved the development of the “Posidonia GOIB” App, which allows any user to know, through geolocation and in real time, the seabed on which they intend to anchor. This way, we ensure that anchoring is done correctly and never on Posidonia oceanica.

The main objective of the project is to improve the knowledge of the distribution of Posidonia oceanica meadows in the Balearic Islands, specifically in the islands of Formentera, Ibiza, Menorca, and Mallorca. It also aims to provide citizens, especially recreational boaters, with accurate information on the exact location of Posidonia oceanica meadows. The goal is to integrate this reference mapping into the “Posidonia GOIB” app developed by the Government of the Balearic Islands. This will allow any user to accurately geolocate and in real time, find areas where recreational boats can anchor, thereby preventing any harm to Posidonia oceanica meadows.


Side Scan Sonar

The Side Scan Sonar of the island of Mallorca has been carried out from 0 to 30 meters. In deeper areas, other existing cartographies have been used.

Satellite images

In the areas closest to the coast, photointerpretation with orthophoto is carried out on clear and transparent areas, followed by on-site verifications where there are doubts.

Review of existing cartography

In Ibiza and Formentera, they have been updated and integrated with new cartography. In Menorca, the main cartography is elaborated by OBSAM.

Use the GOIB Viewer to find the most optimal anchoring location.
