Recorder for cabled stations or integration aboard existing systems (Gliders, AUV) :
Abyssens offers a line of underwater acoustic recorders with high performances in acoustic recording and storage. Thanks to a self noise below sea state zero and a high dynamic range, ambient noise can be monitored together with high level sources.
DORI recorder – XS addresses the issue of long term deployments in coastal areas through cabled stations. In addition, thanks to his very small design and low power consumtion architecture, this underwater acoustic recorder can easily be integrated aboard submarine systems.

Our main options
|✓ Temperature sensor
✓ Vacuum kit (allows you to test the watertightness of the device)
Typical use cases :
Two frequency ranges are available and offer you a complete listening range of the underwater soundscape. These underwater recorders can be used for PAM (Passive Acoustic Monitoring) allowing to listen the ambient noise and its constituents:
anthropogenic sounds : noise radiated by boats, sea works noises as pile driving, drilling or explosions, noise radiated by renewable marine energies
- biologic sounds : marine mammals, fishes and bentic activity
- geophonic sounds : wind, rain, seismic and volcanic activity
High frequency option allows listening up to 250 kHz, which is often requested for detecting clicks from marine mammals, such as harbor porpoises.
