Skildring: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 fish directly from echosounder data. We test various aspects of broadband echosounder use on fish aggregations. We travel to Lofoten/Vestrålen to aid

Skildring:TS-Probe on CRIMAC survey by G.O.Sars in 2020 Nov. Target - herring.TS-Probe is an echosounder-equipped probe that is operated from a research vessel, vertically deployed to up to 1500m depth, in order to study pelagic biological targets (fish, krill, jellyfish, etc.) at close range, both for acoustic echo properties and behavior.
