CENTRE FOR MARINE SCIENCE AND TECHNOLOGY (CMST) WWW.CMST.CURTIN.EDU.AU Dolphin acoustics in the northwest (WAMSI II project: joint project with Murdoch) Sydney/Kormoran Project: To create an immersive, virtual museum experience using deep sea imagine of the story of two ships that sank each other in 1941 (collaboration with UWA) Acoustic assessment of habitat and abundance in the Northern Demersal Scalefish Fishery WA IMOS (Integrated Marine Observing System): collect ocean noise data sets to link with various physical, biological, man-made and climate driven processes

3. An acoustic assessment of habitat and abundance in the Northern Demersal Scalefish Fishery – FRDC Project 2011/022 Collaborators: CMST, Curtin; Kimberley Wildcatch, Licensee; Department of Fisheries, WA Objectives: 1.Characterise seafloor habitat associated with high fish abundance and fishing effort distribution; 2.Identify possible locations of significant biomass outside current areas of commercial effort; 3.Determine relative demersal fish biomass and investigate changes through time. Methods: Attach a multi- frequency (18, 38, 120 and 200 kHz) scientific, split- beam sonar system to a commercial vessel and collect acoustic backscatter during routine operations. To date: 1.>15,000 km of acoustic data collected.2. Video ground-truth data on habitat and fish. 3.Observed spatial relationships for acoustic habitats and in-water biomass.

4. WAMSI II Project 1.2.4 Distribution, abundance and genetic connectivity of Australian snubfin and humpback dolphins across the Kimberley Murdoch University, Australian National University & Curtin University joint project Carry out concurrent passive acoustic and visual observations of dolphins Correlate acoustic and visual detection rates and behaviour Integrate both acoustic and visual data to validate species presence and correlate with relative abundance Investigate geographic variation of humpback and snubfin vocalisations. Aims Roebuck Bay, Cygnet Bay and Beagle Bay Locations Begins April 2013 Courtesy of Deborah Thiele
