Echograms of aquatic organisms observed by a quantitative echosounder around JAPAN →JAPANESE page

What is an Echogram ?

 Echogram is a image obtained by an echosounder. Echosounder transmits ultrasonic waves to detect the position of the sea bottom and fish schools by refelcted ultrasonic waves. In this website, we provide species identified echograms (ground-truthed echogram) obtained around Japan by a scientific echosounder, which can collect the refected ultrasonic waves intensity quantitatively.
