Why Use the i3XO Ecomapper AUV?
A key reason to use the i3XO EcoMapper AUV is when undulating and below-surface water quality mapping is desired. By contrast the HYCAT is a surface-only vehicle. The i3XO brings together an unprecedented array of sensor technologies on an autonomous underwater vehicle (AUV) of its size:
- A specially modified EXO1 water quality sonde, capable of holding any 4 EXO sensors
- Multi-beam, side-scan sonar for high-resolution mapping of the seafloor and surfaces
- Advanced Doppler Velocity Log for bathymetry and downward-looking current profiling
- An optional towable magnetometer, as well as the option to use an expansion port for additional sensors
- A unique internal navigation system that enables 0.3% accuracy of distance travelled and geo-referencing of data points
Examples of work the i3XO has been used for include monitoring cooling ponds at iron mines for environmental contamination and turbidity, to ensure compliance with local regulations. it has been used for identification of unexploded ordnances and search and rescue missions. Dredging contractors have used floor mapping for depth, obstructions, and other details needed prior to dredging, to minimize impacts and guard safety. All sensors have supported spatial water quality profiling in estuaries, lakes and rivers for teaching, research, and regulatory purposes.
