BIO 010 Datasheet DT X AutoMonSys 1BioSonics offers unique and innovative solutions to monitor fish passage and assess behavioral impacts on aquatic animals including marine mammals, fish, and diving birds.

BioSonics sonar systems are often installed in fixed-position deployments to observe the underwater environment over a period of weeks, months or even years at a time. Such long-term observations are essential in monitoring changes in the behavior and for assessing fluctuations in the abundance of aquatic animals.

Applications for this technology include water intakes, marine and hydrokinetic turbine installations, spillways, screens, and fish bypass structures where concerns are raised about the impacts of operations on aquatic species. BioSonics has extensive experience designing and deploying hydroacoustic monitoring systems for a wide range of project applications; from traditional hydroelectric to nuclear power to the emerging ocean renewable energy industry.

  • Unique technology advantage

    BioSonics split beam technology can continuously determine a target's position in three dimensions; range, bearing, and vertical resolution. The position of each target passing through the sound field is calculated by accurately measuring the differences in an echo's arrival time to individual elements in the transducer. Three dimension tracking provides valuable behavioral information used to classify each target. BioSonics unique software incorporates target size, swimming speed, and trajectory data to create "tracks" and classify each target (e.g. as an actively swimming marine mammal, individual fish, a school of fish, or passively drifting debris).

    This cross-section view shows three split beam transducers monitoring from a near shore location to create an acoustic curtain with full water column coverage.

  • System description

    BioSonics sonar utilizes a digital, calibrated acoustic signal to determine target, position, size, and swimming behavior multiple times per second. The result is true 3-dimensional target tracking. Automated Monitoring System features include: "Watchdog" functionality to monitor system performance metrics and send status updates and alerts. Automated real time signal processing to build track lists and email summary reports for all results. Reporting intervals can be hourly, daily, or weekly. Integrated orientation sensors and rotators with programmable scanning modes to optimize sampling volume and maximize monitoring coverage.
