Abstract

Split beam sonar has been used in fish stock assessment, habitat mapping and physical oceanography for over 30 years.  In recent years new advancements in signal processing and software has provided inroads to many other applications.  Acoustics are a preferred tool in fisheries management for both marine and freshwater applications.  My presentation will provide a brief overview of both traditional and non-traditional use of split beam sonar as well as deployment options and current data management options.  In addition habitat mapping and post processing methods will be discussed.
