20210920 CRIMAC associated master student Cecilie Skaale (sup. Tonje Forland) got help from expert acousticians Egil Ona, Tonje Forland, Antonio, and Rokas to set up her experiment in Matre.
Broadband echo-sounders are used in Matre to study the behavior of salmon in net pens with and without sea lice prevention measures - restricted access to surface waters coupled with submerged air-filled dome or walled tube to sea surface for swim-bladder inflation.

2021.11.10-21 CRIMAC acoustics and trawl survey by G.O.Sars in Barents sea.
Ronald (engineer), Rokas (researcher), and Rune (PhD student) having fun with an acoustics equipped probe (TS-Probe) in action. This probe was used to measure acoustic echo properties of small cod and haddock in the Barents sea. Echoes from various types of bottom was also measured for purpose of acoustics-based substrate identification.
Not every research ship around the world has as many scientific echosounders as this probe built at IMR
