Skildring:
Experiment setup in the Austevoll Research Station. The gimballed transducer rig (centre) was deployed by crane of a workboat (seen in the background). The transducer rig was deployed (and held) by four ropes to the depth of 22m inside the fish net pen (net dimensions 12x12x27m). The container office (left) houses the five EK80 transceivers, 12V batteries, and PC running the EK80 software.
