[Image changes to show an animation of the RV Investigator]

[Text appears: RV Investigator Multibeam Surveying]

[Image changes as camera goes under the water to show the hull of the RV Investigator and text appears:  Investigator has a 13.5m x 9.5m gondola, fixed 1.2m below the hull]

[Image changes back to show a picture of the RV Investigator emitting acoustic signals and text appears:  The gondola is fitted with:  Kongsberg EM122 full ocean depth multibeam swath mapping system.   Kongsberg EM710 shallow water multibeam swath mapping system.   Simrad ME70 is a steerable multibeam (up to 45 beams) echo sounder, capable of 3-D images for biomass estimation, fish school characterisation and behaviour studies.  The gondola is fitted with:   Kongsberg SBP120 sub-bottom profiler.   Multi frequency hydrophone.   Skipper DL850 dual axis doppler log.   12 kHz transducer, for underwater communication, e.g. mooring releases and pingers.]

[Image changes to an aerial view of the RV Investigator and text appears:  Investigator can map the sea floor to full ocean depth.]

[Image changes to show the sea floor below RV Investigator, with an arrow appearing to mark a 30 kilometre width, and text appears:  The EM122 has a resolution of 1° x 1° and in deep water has a swath width of up to 30km.  The EM710 has a resolution of 0.5° x 1° and is capable of high resolution surveying to 1000 m.]

[Image changes to an underwater view of the hull of the RV Investigator and text appears:  Investigator’s hull was analysed using computer-based fluid dynamics to ensure the bubbles generated by the hull, and the pattern they formed sweeping down around the ship, wouldn’t interfere with the acoustic equipment.  This was then analysed during tow tank testing.  To further ensure the ship created fewer bubbles, the bow was specially designed avoiding both the use of a bulbous-shaped bow and tunnel thrusters.  Instead, Investigator has a soft nose stem and retractable azimuthing bow thruster.]

[Image changes to show seabed mapping images and text appears:  To maximize the performance of the acoustic equipment, the ship has been built to comply with DNV-Silent-R, to minimize the noise from the machinery on board.  This will increase the range of resolution of seabed mapping, sub-surface imaging, and marine ecosystem monitoring instruments.]

[Image changes to show an animation of the RV Investigator]

[Text appears: RV Investigator CTD]

[Image changes to an aerial view of the RV Investigator and then moves down to the side of the ship where a door opens and the CTD comes out of the ship, suspended over the water on a mechanical arm]

[Camera zooms in on the CTD, and text appears:  CTD stands for conductivity, temperature, depth.  This device collects a wide range of data underwater to help scientists understand the characteristics of the ocean such as currents, its composition, and how it changes over time]

[Image changes back to the CTD suspended over the water and the mechanical arm lowers the CTD into the ocean]

[Image changes to show water sampling bottles on the CTD and text appears:  Water sampling bottles close remotely to collect water samples at different depths]

[Image changes to show the underside of the CTD and text appears:  The CTD unit gathers data using electronic sensors and sends data back to the ship]

[Image changes back to the RV Investigator and text appears:  Investigator uses its thrusters to maintain position above the CTD]

[Image changes to show the RV Investigator stationary above the water and the CTD descending down through the water.  Graphs appear to the right of the image and text appears:  AS the CTD descends through the water column electronics monitor many ocean properties like light levels, pressure and temperature.  Electronics also measure turbidity (how cloudy the water is with tiny particles)]

[Image changes to show an arrow indicating the depth of the water at 7 kilometres, the CTD returning to the surface of the water, and text appears:  As the CTD returns to the surface sampling bottles are closed remotely, to capture water at specific depths.  The water is then analysed to measure concentrations of nutrients like nitrate, phosphate and silicate.  It is also analysed for concentrations of trace elements like iron, which is important for plankton growth.  Onboard the ship, water samples can be analysed for the number and types of plankton]

[Image changes to show an aerial shot of the east coast of Australia surrounded by the ocean currents and text appears:  CTD data collected has allowed scientists map where cold and warm currents travel in the ocean, and to discover the southward movement of the East Australia Current (EAC).  As the EAC moves south, ecosystems are changing, bringing warmer water species to the seas around Tasmania]

[Camera zooms in on the radar emitting microwave pulses]

[Text appears: The radar sends 800 pulses every second.]

[Camera zooms out on Investigator and shows the area where the radar can collect data. Text appears: Data is collected within a 150 km radius from the ship and 20 km into the atmosphere.]

[Camera pans skyward to show precipitation. Text appears: The pulse has a vertical and horizontal signal, called dual polarisation. The returning signal reveals the quantity, location, size and shape of any precipitation.]

[Image changes to show pictures of water, snow and ice. Text appears: Scientists will be able to see if a cloud is made from water, snow or ice]

[Image changes to show an aerial shot of landmasses surrounded by ocean. Text appears: Land-based radars already collect data for scientists. The radar on Investigator will record the first data from the oceans around Australia. Footnote appears: Stuart Ramsden, National Computational Infrastructure, & Todd Lane, the Centre of Excellence for Climate System Science, University of Melbourne.]
