Field notes

The site separates continuous acoustic monitoring from MERA, a restoration system that plays recordings from healthy reefs through underwater speakers. Its project list includes long-duration monitoring around Europa Island, a year-long study in Saint Barthélemy, and reference work in Réunion, alongside a separate photogrammetry offering. Audio excerpts are available through the site and a linked SoundCloud account, while service deployment and content rights are handled by contact.
