Development of Advanced Volume Scattering Instrumentation. A Bottom Moored and Drifting Bioacoustic Sensing Platform and Relay.
1996
Wiebe, Peter H. | Stanton, Timothy K.
The long range goal of this project has been to develop acoustical techniques and instruments for the measurement and analysis of the spatial and temporal structure of oceanic and neritic zooplankton and micronekton populations. In this particular effort, we refined, tested, and evaluated an existing prototype autonomous active acoustic system (the BIOacoustic Sensing Platform And Relay - BIOSPAR) for observation of high frequency (120 and 420 kHz) acoustic backscattering. The system was reconfigured so that it could command and control a newly developed digital echo sounder now produced by BioSonics, Inc. The system has been field tested on two cruises to Georges Bank and the Gulf of Maine.
