Acoustic Zooplankton Fish Profiler (AZFP)
Autonomous, calibrated multi-frequency scientific echosounder for long-term monitoring of zooplankton and fish in oceans, lakes and rivers.
Description
The AZFP is a multi-frequency scientific echosounder for long-term autonomous monitoring of zooplankton and fish distributions.
Key features
- It measures acoustic backscatter at multiple ultrasonic frequencies to detect zooplankton, fish, bubbles and suspended sediments.
- Up to four frequencies can be chosen from 38, 67.5, 120, 200, 333, 455, 769 and 1250 kHz, with non-standard options available.
- Deployments of 12 months are typical and may extend to 18+ months; AUV and glider options exist.
- Each unit is calibrated and verified in ASL's test tank.
Applications
Long-term autonomous monitoring of zooplankton and fish in oceans, lakes and rivers, and detection of bubbles and suspended sediments, on moorings, AUVs or gliders.
