Bio-acoustic Sonar

The Bio-acoustic Sonar measures acoustic signals of plankton and zooplankton on coastal arrays. The sonar emits sound waves into the water column which bounce off organisms back towards the sensor in a phenomenon known as “backscatter.” The more organisms, the higher the backscatter. Some Bio-acoustic Sonars are situated in the coastal environment (ZPLSC), while others are at the open-ocean global arrays (ZPLSG).
