Where are the Fish Acoustical oceanography and DEIMOS
Sound levels • 20 db quiet bedroom • 40 db library • 60 db conversational speech • 90 db street traffic • 130 db jet engine • 140+ db pain threshold
Sound in the Ocean • Water is 800 times more dense that air—so sound is intensified in ocean environments
Fisheries Acoustics • Uses sound to detect, map, and count aquatic species • Animals in the water are complicated scatterers of sound due to their shape, composition, curvature, and behavior.
Do your own analysis • Look at a data stream from the DEIMOS • Look for patterns and shapes in data • What do you think you are looking at? • What do you notice about the picture?
Density of Species • Richer colors=Dense marine organisms • Cooler colors=Less dense organisms
