Water quality. Visual seabed surveys using remotely operated and/or towed observation gear for collection of environmental data has-tracked-changes The objective of BS EN1 Scope This European Standard describes methods, requirements and equipment for remote visual surveillance of organisms and the seabed using still photography and video recording to ensure precise and reproducible data. The main aims of the methods are to record or monitor seabed conditions and organisms on and just above the seabed in a reproducible way at a resolution that is appropriate to the aims of the survey.
