Features


Can collect data continuously at high temporal and spatial resolution for up to one year

The AZFP component is available with up to four frequencies


Can be deployed in bottom-mounted frame or taunt-line moorings 





Applications


The Acoustic Zooplankton Fish Profiler-ice (AZFP-ice) combines the AZFP's abilities to monitor the presence and abundance of zooplankton, fish, suspended sediments and bubbles within the water column as well as the Ice Profiling Sonar's (IPS) ability to measure ice draft. A powerful calibrated tool for scientific research and environmental monitoring in oceans, lakes and rivers.
