The ‘ABB’ concept, a smart independent acoustic system for data collection from various opportunity platforms to provide ecosystem descriptors and indicators

Résumé

Our days there is through the variety of active acoustic transducer systems and the need to collect more and more data for the application of the ecosystem approach to fisheries, as the management of ecosystem uses or the effect of global change on aquatic ecosystem. From these observations, a consensus among researchers of several disciplines (e.g. fisheries, marine ecology, biogeochemistry, ecosystem modeling, etc.) to develop a system which could provide long time series i.e. to set observatories in order to observe change or at least record the state of the different compartments of the ecosystem (fish, bottom, planktonic layer, fish mammal, oxycline, etc.) and/or their interactions. Whatever the platform which could be instrumented the same problem occur dealing with acoustic sensor systems for their automation: define ad hoc parameters, the electrical supply availability, the data recovery possibilities and how to set the system on the structure to avoid interferences, damages and allow transducer calibration procedure. For all these reasons we propose to develop an Acoustics Blue Box ‘ABB’ allowing different kind configuration taking into account the transducer specificity and the local environmental characteristics. The concept of the ABB is to set acoustics transducers on an autonomous independent system which could be set on various platforms to record relevant information according to a specific scientific goal. Apart from fishing and commercial vessels we also identified other platforms as petroleum and gas off-shore platforms, bottom stations, drifting and anchored buoy systems, AUV, across various environment from deep sea to shallow water areas, and in marine, brackish, or freshwater environment. The proposal is to provide the main specification required to develop the ABB which could be set by the platform owner without producing interferences with their own exploitation systems. The continuous quick advance in technology allow envisaging for a near future: very high data storage capacity, fast Ethernet data transfer, and the availability of efficient independent power supply solutions which were since 10 years the major brakes to the use of analogous systems. Lastly we present the main descriptors and indicators which could be delivered from active acoustic transducers installed inside the ABB to develop local and wider observatories.
