Field notes
The platform separates observation from intervention: UPAM records reef soundscapes with hydrophones, while MERA broadcasts selected recordings through an underwater speaker during spawning periods. The homepage names acoustic indicators including species activity, trophic fish-group biomass, and noise pollution, and also lists 3D photogrammetry. Its project index covers multiple island and coastal territories, including Réunion, Mayotte, Saint-Barthélemy, Guadeloupe, Europe, and New Caledonia.
