BioSonics offers training for all levels of user experience. You can choose to attend one of our Hydroacoustic Assessment Workshops, or we can bring the training to your location – either in the classroom or on the job. If you’re interested in advanced training for a particular hydroacoustic application, please contact us.

Fisheries & Aquatic Habitat Assessment Workshop

Our workshops are held at our company headquarters in Seattle, Washington. The course content includes a review of hydroacoustic theory as well as practical training and tips for echo sounder operation, field calibration, and transducer mounting. Combining lecture, demonstrations, laboratory exercises, and a mobile survey on Lake Washington, our workshops provide an overview of the latest techniques for hydroacoustic data collection and processing.

Topics covered include:
  • Echo sounder Operation and Mobile Survey on Lake Washington
  • Physics of Sound in Water and Principles of Hydroacoustics
  • Fisheries and Plankton Assessment
  • Submerged Aquatic Vegetation (SAV), Bottom Classification, Bathymetry Assessment, and Mapping
  • Survey Design and Case Studies
  • Software Overview, Data Processing, Analysis, and Reporting Techniques
