CRIMAC survey with G.O.Sars, 2022.11.27-2022.12.03. From Tromsø and Kvænangen to Lofoten, Vestrålen and Myre. We test new ideas and methods in using scientific echosounders and sonars to study fish. We study herring in Kvænangen fjord with broadband echosounders pointing downwards and sideways to port and starboard. We test and measure the size of

We study herring in Kvænangen fjord with broadband echosounders pointing downwards and sideways to port and starboard. We test and measure the size of fish directly from echosounder data. We test various aspects of broadband echosounder use on fish aggregations. We travel to Lofoten/Vestrålen to aid

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 surf

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.

The first CRIMAC SFI scientific survey on broadband acoustics. G.O.Sars chasing after herring in Troms fjords (Kvænangen) and then into the open sea a third of the way to Iceland (I think herring got tired by that time, as did we).
