Biophysical Processes in the Torres Strait Marine Ecosystem II. Geoscience Australia Marine Survey 273. Underwater Video Data.Note: This metadata describes the dataset in accordance with the ANZLIC (Australia New Zealand Land Information Council) Core Metadata Guidelines Version 2. Dataset citationANZLIC unique identifier: ANZCW0703009568 Title: Biophysical Processes in the Torres Strait Marine Ecosystem II. Geoscience Australia Marine Survey 273. Underwater Video Data. CustodianCustodian: Geoscience Australia Jurisdiction: Australia DescriptionAbstract: Video footgae of the asea bed was collected to characterise the substrate, morphology, habitats and benthic biota in the study area. A vidoe camera was lowered to the seabed and recorded a minimun of three minutes of video. Additional information regarding this dataset is contained in the Survey report.

Data currencyBeginning date: 2004-10-08 Ending date: 2004-10-28 Dataset statusProgress: Complete Maintenance and update frequency: Not Known Access
Access constraints: Short versions of the underwater video footage are available via the MARS database and web pages. www.ga.gov.au/oracle/mars. The full length video is stored on VHS and mini DV tape. Free Data DownloadData qualityLineage: All data was collected on the Survey between 8 and 28 October 2004. Approximately 3-5 minutes of video was captured at each site and 1.5 minutes was capured every 20 minutes for the 24-hour stations. At each site the the video footage recored was edited down to 20-30 sedond snippets that showed the major habitats, biota and sedimentary processes that were observed at each station. The video was edited using standard video editing soft ware. Positional accuracy: The survey was conducted on the vessel R.V James Kirby. The vessel was equip with a differential GPS giving locational accuracy to within 1m. Attribute accuracy: Grab samples and sub samples from 2cm interval down the vibro cores were ananysied form percentage gravel sand, mud and for percentage of carbonate in bulk sample, and in the gravel sand and mud fractions. Cores were also analysied for physical properties by the Multi Sensor Core Logger. Water samples were filtered to determine the concentartion of suspended solids. Under water video footage has been described. Logical Consistency: Not known Completeness: Final Report has been published. All 20-30 second snippets are available via the Marine Samples (MARS) database web page. www.ga.gov.au/oracle/mars/ Contact information
