Biological fouling (bio-foudling) often degrades acoustic and optical data after several months of instrument deployment. Organisms grow on the instrument transducers and gradually block acoustical pulses and light transmission, which results in a gradual drift of the beam attenuation. Care has been exercised to remove data that have been affected by bio-fouling.
