Curated underwater video highlights of marine protected areas (IMAS, UWA & collaborators)
공공데이터포털
This data is a national compilation of video clips predominantly derived from underwater video sampling techniques (e.g. BRUV, Stereo-BOSS) for quantitative sampling of abundance, body size, and diversity of demersal fishes. The curated collection also includes regional 'compilation' videos highlighting a particular marine protected area or region of interest. Current contributors to this data compilation are IMAS, UWA, Geoscience Australia and the NESP Marine Biodiversity & Marine and Coastal Hubs, with the intention that this collection will grow to encompass collections from other research organisations around Australia. As of August 2024, this dataset includes video in and around Abrolhos, Arafura, Apollo, Beagle, Bremer, Christmas Island, Cod Grounds, Coral Sea, Dampier, Eastern Recherche, Flinders, Franklin, Freycinet, Gascoyne, Geographe, Huon, Lord Howe, Montebello, Murat, Murray, Ningaloo, Oceanic Shoals, Perth Canyon, South Tasman Rise, South-west Corner, Tasman Fracture, Two Rocks, and Zeehan Australian Marine Parks (AMPs), and of Bathurst Channel in the Port Davey Marine Reserve. The dataset allows examination of changes in fish communities over time as part of ongoing monitoring of these regions. This record represents a 'parent' record of multiple collections. See individual 'child' records for more information on specific regional collections.

공공데이터포털
Fish and shark assemblage data are being obtained from the analysis of Stereo-BRUV footage captured in April 2015. Data is comprised of raw camera output stream files (.MTS and .MP4) for 133 Stereo-BRUV drops in shallow water (~10m) from Exmouth to Barrow Island, Western Australia. Files are less than 1.9GB and total approximately 2.2TB. Videos are structured within Stereo-BRUV drops (identified with an OpCode i.e. NCB1-NCB272) with a left and right camera folder within each drop. Videos are lodged with the iVEC Data Store - https://data.ivec.org The Pilbara Marine Conservation Partnership (PMCP) was an initiative designed to enhance the net conservation benefits of the globally-significant coral reef ecosystems of the Pilbara (Western Australia) by providing an assessment of the condition and trajectory of key ecological values. These assessments were designed to inform and complement existing governance and management arrangements and the PMCP is intended to provide ongoing advice and assessment for conservation efforts in the region, providing lasting benefits. The PMCP concept is based on three core ecological components, namely: Coral Reef Health - concentrating mainly on habitat forming primary producers. Fish and Sharks - their community structure, interactions and impacts on lower trophic levels. Environmental Pressures - physical and anthropogenic factors that influence the condition of reefs and associated biota.
Surveys of fish-habitat associations using Baited Remote Underwater Video Stations (BRUVS (TM)) offshore from Port Hedland, Western Australia

In July 2012, baited remote underwater video stations (BRUVS (TM)) were deployed in the vicinity of Port Hedland, in two areas parallel to the coast (inshore and offshore) on either side of the shipping channel and some dredge spoil grounds, in depths of 4.6 to 24 metres.The survey design specified the deployment of 230 BRUVS (TM) at random within grids of the two study areas, at a spacing not less than 450 metres apart, to minimise the likelihood of individuals moving between stations and being double-counted. Of the 230 BRUVS (TM) deployed during the field campaign, 221 produced imagery of sufficient quality for analysis.Commencing immediately after reaching the seafloor, 60 minutes of bottom-time was analysed for all video recordings, regardless of whether video extended longer. Data was recorded using a purpose built interface and included identification to species level and life stage (adult or juvenile) of all vertebrates, relative abundance (MaxN ; maximum number visible at any single point on the tape), time of arrival and the time elapsed before MaxN and feeding occurs. Depth and GPS position of each deployment, estimates of water clarity and the timing of ancillary events such as feeding activity and loss of bait bag were also recorded.The habitat at each station was classified by reviewing an image of the seafloor from each of the BRUVS (TM) sampling stations. To provide quantitative estimates of habitats, the percentage cover (to the nearest 10%) was then determined for six categories of (abiotic) substratum, summed to 100%, and for 12 categories of (biotic) epibenthos, also summed to 100%. This study was undertaken to provide baseline estimates of fish diversity and relative abundance in direct relation to habitat and depth within inshore and offshore areas in the vicinity of Port Hedland, where a large expansion of port facilities will be accompanied by dredging and relocation of dredge spoil on adjacent seabeds in the local region.

Fish and shark assemblage data are being obtained from the analysis of Stereo-BRUV footage captured in September 2015. Data is comprised of raw camera output stream files (.MTS and .MP4) for 92 Stereo-BRUV drops in shallow water (~10m) around the Mackeral Islands, Western Australia. Files are less than 1.9GB and total approximately 1.5TB.
