Brief description
The Flinders Commonwealth Marine Reserve (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 blueprint for the sustained monitoring of the South-east CMR 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 Systems (BRUVS), deep- water BRUVS (to 600 m), towed video and digital stereo stills. This resource contains the deep-water BRUVS footage captured on the slope (~500m depth) of two sites: the Flinders CMR and the adjacent Cape Barren fisheries closure. At each site 3 stereo deepBRUVS were deployed over a 3-day period, during which they recorded between 11 and 15 1-hour sampling events each.Lineage
Statement: Two sites - inside the Flinders CMR and in the adjacent Cape Barren Fisheries closure at ~500m depth were sampled. At each site, three deep stereo baited remote underwater video systems (deepBRUVS) a modified version of traditional BRUVS developed at CSIRO for long-term, deep deployments, were deployed. Each deployment was over a 3-day period during which each deepBRUVS recorded between 11 and 15 1-hour sampling periods. A sampling period consists of the cameras turning on, then the lights switching on, followed by the release of a baitplume (liquid slurry of pilchards) to attract fish. For the deployment at the Cape Barren Closure site a baitbag (containing whole pilchards) was also attached to the bait-plume piston, to observe if fish were more attracted to the bait than the baitplume. Raw electronic video files (.MTS files) were collected. The files were renamed such that the survey identifier, sample number, clip number, port or starboard camera, and UTC date/time are encoded in the filename. Note, the UTC time can be displayed in the video showing subtitle track1. Footage will be analysed using a package from SeaGIS called EventMeasure and be the subject of a separate metadata record.Notes
