Introduction to Underwater Video Operations
Underwater video operations are routinely conducted during NEFSC fisheries acoustic surveys to identify acoustic targets. The underwater video system is typically deployed by portable winch as the vessel drifts over backscattering layers. The system includes stereo video with attitude sensor that provides us with the ability to determine the in-situ 3-dimensional orientation of acoustical targets. The individual acoustic measurement of a given organism can vary by its orientation and behavior. Future research will apply this capability towards validating theoretical backscattering models for various species. Self-contained video systems have also been developed for attachment to our midwater trawl operations to examine gear selectivity.
