ICE-POPE 3

Part of the work we will conduct with the technical team of ArcticABC in Ny-Ålesund is to test acoustic instruments, in particular Acoustic Zooplankton and Fish Profilers (AZFPs). Two AZFPs will eventually be deployed on ICE-POPE 3 (Ice-Tethered Platform Cluster for Optical, Physical, and Ecological Sensors), one looking upward and the other downward, to study both zooplankton and fish under ice but also at greater depths in the water column (see attached figure). Before we install these instruments on the autonomous ICE-POPE and leave them operating in the Arctic for several months, we need to test the different settings we are planning to use and make sure they allow 1) a good enough resolution to detect small organisms near the ice cover; and 2) low energy consumption that enables data collection over a complete year cycle on the same battery pack.
