SmartPAM+ monitors both turbidity and underwater noise impacts of coastal maritime constructions.
It is the result of past development phases lead by Quiet-Oceans in partnership with UPC.

SmartPAM+ indeed originates from the existing Smart-PAM developed by Quiet-Oceans, a system that monitors underwater noise. Based on a range of buoys designed to comply with local conditions, it includes underwater noise, bioacoustics and AIS sensors as well as embedded electronics to translate measured data into usable information. The necessary processed data is then transferred in real time through several wireless communications links.


  • Offers a unique solution to marine construction projects, which must mitigate their underwater noise impact in accordance with the EU Marine Strategy Framework Directive.
  • Allows companies and governments to check if underwater noise levels comply with regulations and to avoid any physiological damage on marine mammals.
  • Has been successfully tested and implemented in two marine protected areas in the Atlantic and the Caribbean and at one coastal construction site in the Mediterranean.
  • Offers real time information flow guarantee that no marine mammal is too close to the works area before construction begins every day.

In the framework of the project, a number of improvements will be done on Smart-PAM to achieve these features:

  • Addition of a turbidity sensor (choice, integration, tests);
  • Improvement of the monitoring capability of biological activity, especially of fish and juveniles (recording of such activity, training of algorithm, tests).

Thanks to AGESCIC project, SmartPAM+ will additionally integrate turbidity monitoring.
To sum up, Smart-PAM will be used in this project to:

  • assess the performance of the SUBSEA QUIETER membrane and HAREST;
  • check the compliance with permitted levels;
  • avoid any acoustic-related physiological damage on marine mammals to comply with regulations.
