Statement: *AUV details* Surveys were conducted with a state-of-the-art Autonomous Underwater Vehicle (AUV), which is operated by the Australian Centre for Field Robotics (University of Sydney) and part-funded by IMOS. The submersible is equipped with a full suite of oceanographic instruments, including a high resolution stereo camera pair and strobes, multibeam sonar, depth, conductivity and temperature sensors, Doppler Velocity Log (DVL) including a compass with integrated roll and pitch sensors, Ultra Short Baseline Acoustic Positioning System (USBL) and forward looking obstacle avoidance sonar. For biological survey work, the vehicle is also fitted with a Wetlabs Eco Puck, measuring chlorophyll-a, CDOM and scattering (red), and an Aanderaa Optode, measuring dissolved oxygen concentrations. The ‘flight path’ for each AUV dive can be precisely pre-programmed with a range of sampling designs, depending on the ecological question at hand (see below). The AUV was capable of conducting dives of up to 3 hours (limited by battery-life) and 3 or 4 dives per day. The vehicle was operated and deployed by a team of 4 scientists/technicians from ACFR; surveys were conducted from the CSIRO-operated research vessel ‘Linnaeus’ in April 2010. *Survey locations and design* Long-term monitoring was established at 3 key locations within the WCB; Rottnest Island (‘Rottnest’), Jurien Bay (‘Jurien’) and The Houtman Abrolhos Islands (‘Abrolhos’) (Fig. 2). The key objective of the sampling was to survey predominantly rocky reef/coral habitat that could be established as LTM sites and revisited as part of monitoring efforts. As such, sites were selected, based on bathymetry maps and existing knowledge (i.e. Marine Futures project), to target moderate to high relief reef. At each location, replicate sites were chosen along a depth gradient, with 2 sites at 15, 25 and 40 m depth. At Rottnest, one of the sites at both 15 and 25 m was positioned within the Kingston Reef marine sanctuary, to enable cost effective monitoring of this ... |
