Sound as a diagnostic tool for coral reefs' state and functioning

For the first time, passive acoustics enables standardised and continuous monitoring of coral reefs.

We will work together to choose the relevant sites and go all the way to put together customized coral reef protection measures.

Our custom scientific reports provide critical metrics about coral reefs' state and functioning and can be visualised on our dedicated website.

What information do we obtain through soundscapes?

MONITORING OF BIOLOGICAL ACTIVITIES

Assessment of the overall ecological state of a site using ecoacoustic indices
Assessment of the biomass of fishes within each trophic group
Quantification of the activity of key species or groups of species
Quantification of the diversity and abundance of biological sounds

MONITORING OF HUMAN ACTIVITIES

Quantification of noise pollution (per hour/per day)
Monitoring of no-entry areas - count of the infractions
Quantification of divers presence

Why conduct passive acoustic monitoring with Reef Pulse?

Compare sites with each other and with others in the region to identify conservation priorities
Monitor no-entry areas and quantify infractions
Evaluate management measures effects over time (e.g., protection of a given area, creation of artificial reefs, species reintroduction)
Understand resilience mechanisms after bleaching events or local impacts (e.g., pollution, terrigenous inputs)
Identify key reproductive periods for species with patrimonial or commercial interest
