Recorder for long term deployments :

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 – L addresses the issue of long term deployments in coastal areas.

Key technical specifications

High dynamic range up to 110 dB

High storage capacity up to 16 TB

Raw data storage (.wav) on 24 bits

Autonomy of 5.6 months in continuous recording (energy & storage)

Self noise below sea state zero

Software configurable amplification gain and high pass filter using WiFi (without opening the recorder)

Remote software update of the recorder

Clean and secure access to SD cards (without contact with electronics)

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.

DaViS : DAta VIsualization Software

A post treatment dynamic visualization of the data is possible with the dedicated software: DaViS. It performs acoustics analysis in replay mode from .wav file of your DORI recorder.

DaViS displays the spectrogram, the temporal evolution of Sound Pressure Level (SPL), the Power Spectral Density and the third octave band levels. In addition, this software allows an audio listening.

Gain and sensitivity of hydrophone are automatically filled. The sound levels are directly shown in dB re 1µPa. This software is compatible with windows and free of charge (supplied with any recorder). The tools and graphs are user friendly.
