BioSonics DT-Xu Echosounder

Our BioSonics hydroacoustic echosounder installed on the Folger Deep instrument platform includes three transducers, at frequencies of 38, 123 and 210kHz. These transducers convert electrical signals from the transmitter into acoustic pulses sent out into the water. When the pulses strike animals or other objects in the water, echoes are produced, which can be detected and converted by the transducers back into electrical signals. Software is then used to determine distances, sizes, concentrations and movements of organisms and other objects in the water.

Discussion

BioSonics DT4 format and ASL AWCP data are supported by the Echoview software (www.echoview.com) for analysis of echosounder data for fisheries, zooplankton and other water column applications.

A public forum (www.fisheriesacoustics.com) is available to connect researchers around the world working in hydroacoustic data analysis and research.
