The new Simrad EK60 scientific echo sounder system

A widely used tool for fish abundance estimation and other marine research is the scientific echo sounder. Acoustic information obtained from scientific echo sounders such as target strength and target position can be valuable for describing individual targets whereas measurements of volume backscattering strength are suitable for describing a large number of targets distributed over a volume of water. The new Simrad EK60 scientific echo sounder system provides high‐quality target strength, target position, and volume backscattering strength measurements over a large dynamic range for a wide range of frequencies (18–200 kHz). An overview of the EK60 will be presented and operation of the echo sounder will be demonstrated. The presentation will include demonstration of the calibration procedure of the EK60.
