Brief description
The Flinders CMR survey was a pilot study undertaken in August 2012 as part of the National Marine Biodiversity Hub's National monitoring, evaluation and reporting theme. The aim of this theme is to develop a bluepint for the sustained monitoring of the South-east Commonwealth Marine Reserve Network. The particular aims of the survey were twofold; 1) to contribute to an inventory of demersal and epibenthic conservation values in the reserve and 2) to test methodologies and deployment strategies in order to inform future survey design efforts. Several gear types were deployed; including multibeam sonar, shallow-water (less than 150m) Baited Remote Underwater Video (BRUVs), deep- water BRUVs, towed video and digital stereo stills. This resource contains the shallow-water BRUV footage captured on the FLinders CMR shelf (less than 150 m). Stereo BRUV's were deployed using a probabalistic and spatially-balanced survey design called Generalized Random Tessellation Stratified (GRTS). Habitats were identified in a previous multibeam survey and consisted of 'mixed reef' (containing patchy reef) and sand. Mixed reef habitat was targeted in this survey (9 GRTS mixed reef sites versus 3 sand sites). A total of 60 stereo BRUVs were deployed. Data contained here represents footage collected using these drops and the associated scored data (abundance (MaxN) and lengths).Lineage

Statement: Stereo Baited Remote Underwater Video (BRUV) was collected from the Flinders Commonwealth Marine Reserve (CMR) shelf environment (less than 150 m). A cluster of five BRUV's were deployed at each site in a spatially balanced Generalized Random Tessellation Stratified (GRTS) design. BRUVS were deployed for a soak time of 1 hour. Captured video files were downloaded from the BRUVS after each drop. Two different video systems were used to capture video, Cannon HFM300 High Definition Cameras were used where possible and JVC Everio Standard Definition as back up. Upon return the native file of the footage (.MTS Cannon, .MOD JVC) was converted to .avi. This record contains the raw .avi footage. Footage will be analysed using a package from SeaGIS called EventMeasure and be the subject of a seperate metadata record.
