This platform is a custom designed and developed mid-size robotic vehicle built at the Australian Centre for Field Robotics. This AUV has been designed for imaging over complex underwater bathymetry and for deployment off smaller vessels than AUV Sirius. The submersible is equipped with a suite of oceanographic sensors including high resolution stereo cameras (6MP each), depth sensor, Doppler Velocity Log (DVL), Compass, Inertial Measurement Unit (IMU), Ultra Short Baseline (USBL), forward and downward looking obstacle avoidance sonar and a conductivity/temperature sensor (Aanderraa). The vehicle is controlled by an on-board PC stack which is used to log sensor information and run the vehicle's control algorithms. The vehicle has demonstrated its capacity to collect high resolution, near bottom imagery on trajectories over rough terrain that has been used to generate 3D meshes and ortho-mosaics. {"type": "Polygon", "coordinates": [[[112.0, -44.0], [154.0, -44.0], [154.0, -9.0], [112.0, -9.0], [112.0, -44.0]]]} 112.0 154.0 -44.0 -9.0 AUV | Autonomous Underwater Vehicle CTD (Conductivity-Temperature-Depth Profilers) Cameras | Still Cameras - underwater Chemical Oceanography Coloured Dissolved Organic Matter (CDOM) Current Meters/Profilers | Acoustic Doppler Current Profiler (ADCP) Data Loggers Digital Imaging (acquisition and/or analysis) Field Surveys | Underwater Surveys Fluorometers IMOS Node | NSW-IMOS | New South Wales Integrated Marine Observing System Oceans | Bathymetry | Seafloor Topography Oceans | Bathymetry | Water Depth Oceans | Ocean Chemistry | Carbon Dioxide Oceans | Ocean Chemistry | Chlorophyll Oceans | Ocean Chemistry | Nutrients Oceans | Ocean Chemistry | Organic Matter Oceans | Ocean Chemistry | Oxygen Oceans | Ocean Optics | Fluorescence Oceans | Ocean Optics | Turbidity Oceans | Ocean Temperature | Water Temperature Oceans | Salinity/density | Conductivity Physical Oceanography SONAR Seabed Vehicles States, Territories (Australia) | Queensland States, Territories (Australia) | South Australia States, Territories (Australia) | Tasmania States, Territories (Australia) | Western Australia Turbulence Sensors Website of the Integrated Marine Observing System (IMOS) documentDigital HTML Website of the Australian Ocean Data Network (AODN) documentDigital HTML Unnamed resource documentDigital License Graphic PNG Unnamed resource documentDigital HTML
