Autonomous underwater recorder
Colmar Italia supplies and rents underwater acoustic recorders for environmental monitoring and for PAM (passive acoustic monitoring) operators from the French company Rtsys exclusively for Italy.
These systems can be configured with a maximum of four low-power Co.l.mar hydrophones, guaranteeing autonomy in terms of duration of up to several months depending on the recording settings chosen.
The fields of application are:
- monitoring of underwater anthropogenic acoustic noise
- Marine biology
- underwater acoustic monitoring
