Together with Océanopolis, CHORUS set up an laboratory facility composed of six identical tanks dedicated to controlled “micro”-acoustics experiments. The aquariology team (picture) at Océanopolis guarantees for water quality and the animal’s well being, also over long time periods.
For long-, mid- and short-term field experiments, we design and apply moorings and hydrophone supports that are best adapted to the objective of the study. Most supports are suitable for the multichannel broadband recorders from RTSYS (see below). Drifting buoys are used for most surface recordings.
For the study of soundscapes, in particular its natural components (weather, benthic sounds), most sensors we use are sea-state zero (HTI-92) or B&K 8106 hydrophones. For the laboratory experiments, we often make recordings using a high-quality amplifier (B&K Nexus amplifier) connected to a PC or portable digital recorder (Tascam DR-680).
