Flythrough movie showing the bathymetry, seabed habitats and biota of the outer continental shelf within the Flinders Commonwealth Marine Reserve (CMR), offshore from Flinders Island northeast Tasmania. The bathymetric image is derived from multibeam sonar collected by Geoscience Australia in 2012 using a 30 kHz Simrad EM3002 system on RV Challenger. Videos and seabed images were collected by the University of Tasmania and CSIRO as part of the same field program. Key features on the shelf bathymetry include low profile reefs, flat sandy seabed and the heads of two submarine canyons. The reefs provide hard substrate for sponge gardens whereas the sand flats are mostly barren. The two submarine canyons are sites of local upwelling, and attract large schools of Tasmanian Striped Trumpeter. The Flinders CMR is a study site for the Marine Biodiversity Research Hub, funded through the National Environmental Research Program (NERP). ..

Flythrough movie showing the bathymetry of the continental shelf within the Oceanic Shoals Commonwealth Marine Reserve (Timor Sea), highlighting carbonate banks and pinnacles as benthic habitats. The bathymetric image is derived from multibeam sonar collected in 2012 using a 300 kHz Simrad EM3002 system on RV Solander and gridded at 2 m resolution. The Oceanic Shoals Reserve is a study site for the Marine Biodiversity Research Hub, funded through the National Environmental Research Program. Survey work was carried out as a collaboration between Geoscience Australia, the Australian Institute of Marine Science and University of Western Australia. Further information is provided in GA Record 2013/38.

Flythrough movie showing the bathymetry of the shelf surrounding Lord Howe Island (NSW), with examples of seabed habitats and biota. The bathymetric image is derived from merged grids (8 m and 40 m resolution) that incorporates multibeam sonar collected in 2008 using a 30 kHz Simrad EM300 system on RV Southern Surveyor, legacy sonar data from various sources and satellite-derived bathymetry (grid development detailed in GA Record 2010/36). Key features on the shelf bathymetry include a drowned reef that encircles the island and intervening areas of sediment-covered basins. Lord Howe Island shelf is a study site for the Marine Biodiversity Research Hub, funded through the Commonwealth Environment Research Facilities (CERF) programme. Further information is provided in GA Record 2010/26.

Full Version - shows orthographic and fly-through sequence for each of 5 scenarios with a combined max. inundation outline fly-through at end. Description. - Tropical Cyclone Alby passed close to the southwest corner of West Australia on April 4th 1978. Large waves and a storm surge generated by the northerly winds caused substantial coastal erosion along the Lower West coast particularly in the Geographe Bay area. Low-lying areas at Bunbury and Busselton were flooded, forcing the evacuation of many homes including the Bunbury Nursing Home. An approximate 1.1 m storm surge at Busselton caused the tide to peak at 2.5 m about 1 m above the highest astronomical tide. The Busselton Jetty was severely damaged. At Fremantle the surge was about 0.6 m causing a high tide of 1.8 m, about 0.5 m above the highest astronomical tide. [From BOM - http://www.bom.gov.au/weather/wa/cyclone/about/perth/alby.shtml - Retrieved 21/01/2010] This movie displays the results of a number of simulated storm surge events caused by an equivalent storm to Tropical Cyclone Alby on the current built terrain of Mandurah, and projected 2100 coastline with 0.5, 0.8 and 1.1m rises in sea level. Scenario A TC Alby equivalent at current sea level Scenario B Worst case TC Alby equivalent with current sea level Scenario C Worst case TC Alby equivalent in 2100 with 0.5m sea level rise Scenario D Worst case TC Alby equivalent in 2100 with 0.8m sea level rise Scenario E Worst case TC Alby equivalent in 2100 with 1.1m sea level rise

In December 2010, the Northern Territory Government (NTG) announced funding for high priority environmental monitoring and research activities in Darwin Harbour. Following the announcement, the Darwin Harbour Habitat Mapping Program was developed and managed by the Department of Land Resource Management (DLRM). Under the Program, DLRM collaborated with GA, the Australian Institute of Marine Science (AIMS), and the Darwin Port Corporation to undertake multibeam and backscatter data acquisition for the Darwin Harbour. This flythough presents seabed bathymetry compilations for the Darwin Harbour in the Northern Territory. These videos are intended for potential public release. The overall objective of the INPEX Environmental Offset program `Mapping Marine and Estuarine Benthic Habitats in Darwin and Bynoe harbours is to improve knowledge of the marine habitats in the Darwin and Bynoe harbours region by producing thematic habitat maps to underpin marine resource management decisions.

Flythrough movie showing the bathymetry of Carnarvon shelf, highlighting benthic habitats at Point Cloates. The bathymetric image is derived from multibeam sonar collected in 2008 using a 300 kHz Simrad EM3002 system on RV Solander. Key features on the shelf include a prominent ridge at 60 m water depth and a complex area of smaller ridges and mounds across the inner shelf. The ridges and mounds provide hard substrate for diverse coral and sponge communities. The Carnarvon shelf is a study site for the Marine Biodiversity Research Hub, funded through the Commonwealth Environment Research Facilities (CERF) programme. Survey work was carried out as a collaboration between Geoscience Australia and the Australian Institute of Marine Science. Further information is provided in GA Record 2009/02.
