Long-term Passive Acoustic Monitoring is the foundation of the entire program and it is achieved through the use of non-invasive underwater recorders. We are currently focused on the northernmost portion of the MesoAmerican Reef, continuously monitoring at The Listener sculpture site in Punta Nizuc, and intermittently at two other sites located at Isla Mujeres and Isla Contoy. We have also incorporated sensors for temperature and light along with the acoustic sensors.


Our plan for expanding the monitoring is focused on:

1. upgrade intermittent monitoring sites to continuous monitoring.
2. add additional monitoring sites south along the entirety of the MesoAmerican Reef, including the rest of the coast of Quintana Roo, Mexico, and into Belize and Honduras.
3. Monitor additional parameters, such as salinity and pH.
4. Design and construct our own devices for soundscape monitoring.
5. Create a network of real-time monitoring stations, with autonomous pattern analysis, and powered with renewable energy and without the use of land-based cables.

To realize our vision for the evolution of this project we are growing our logistical, administrative, research, and dive teams.
