August 2019 Ningaloo DMR BRUV field trip - part 1of 3

Name, Brief Description and owner: Baited Remote Underwater stereo-Video (BRUV) systems (6 in total) were used. All equipment (BRUVs, weights, cameras, lights, ropes, etc.) belonged to UWARelevant component details: make, model, serial number, firmware version, settings:Stereo‐BRUV systems consisted of a frame, protecting 2 convergent video cameras inside waterproof housings (plus one rear-facing video camera) and 2 lights (one forward-facing and one rear-facing), attached to a base bar, with a baited container fixed in front of the cameras. Systems were tethered by rope to surface buoys to facilitate relocation and retrieval. Weights were added to frames due to the current and depth in the area.Cameras used: 2 x Canon HG 25 (forward facing) with the follow settings:•\tFocus: Manual (3.0m)•\tRec Program: P)•\tImage stabilizer: OFF•\tFacial recognition: OFF•\tRecording mode: MXP•\tFrame rate: PF251 x GoPro Hero 3+ (backwards facing), taking photos every 60 seconds.Cameras were calibrated at UWA prior to and at the conclusion of the field trip, using SeaGIS software Cal.Contains folders:Backwards, Forwards, New Convert, Videos DoneLineage: Stereo‐BRUV systems consisted of a frame, protecting 2 convergent video cameras inside waterproof housings (plus one rear-facing video camera) and 2 lights (one forward-facing and one rear-facing), attached to a base bar, with a baited container fixed in front of the cameras.
