Hydroacoustics

This Backgrounder reviews the basic principles of hydroacoustics – using the echoes of transmitted high-frequency sounds to generate acoustic maps of the water column and the biota swimming within it. Here I limit my focus to the basic concept, design considerations for hydroacoustic surveys and means of interpreting echograms.

This and other Backgrounders are available on the Reports page.
