Backscatter over the real seafloor. Each survey is shown as a depth-layered summary (about 60 columns per transect, 2 m layers); use Cell detail in the panel on the right to show every cell of chosen surveys. Not multibeam — each column is a single-ping estimate, not a measured school outline.
Tip: scroll zooms toward the mouse, double-click recentres on a spot, and holding Shift makes zoom and pan much faster. If the fish are hard to see, lower the Seabed opacity (or switch the solid seabed off) in the panel on the right, and zoom in.
