Skildring:
Three of five scientific echosounders (orange thingies are the antenna/transducers). This is a gimbaled transducer arrangement for vertically upwards orientation of the acoustic beams when deployed to 25m depth. Installed under salmon net pen, looking through and up. Broadband and narrowband acoustic echo observations of individual fishes.Lovely fieldwork in Matre Research Station last week for CRIMAC project. Some net pens with salmon are now equipped like RV G.O.Sars, that is with full researc
