It transmits an acoustic pulse of programmable duration, then listens for the echo from targets in the water column. It returns a value of the acoustic intensity for every 12.5 cm. It can be deployed up to 150 m beneath the surface, looking upward, or from the surface looking downward."@en ; sdo:inDefinedTermSet ; sdo:name "ASL Environmental Sciences Zooplankton Acoustic Profiler (ZAP) 200 kHz {Water Column Profiler (WCP)} echosounder"@en ; sdo:termCode "SDN:L22::TOOL1420" .
