Echogram

Caption

This echogram section displays the acoustic data showing the vertical and temporal distribution of fish within a 24-hour cycle. Contouring represents the presence (orange) and absence (white) of fish within the water column. Fish are retreating to 400 and 600 meters depth during the day and spending time in the upper 200 meters at night. The almost vertical lines show the fish swimming down at sunrise and up at sunset.
