The vehicle will be deployed vertically from a cable winch through the ice deployment hole to the ocean water underneath. The vehicle will be deployed vertically from a cable winch through the ice deployment hole to the ocean water underneath.
The forward-looking and downward-looking camera images are sent directly to the surface (through the optical fiber
tether) for human operator viewing. A computer located at the surface is used to display vehicle state information as well as the visualization of sonar and video data for use by the human operators. Both the sidescan sonar and forward-looking sonar are also sent to the surface directly without any processing to enable real-time human analysis of the environment structure.
Image and sonar data will be captured and saved at the surface for future offline analysis. All other sensor information is also sent to the surface for recording and future offline analysis, in particular the acoustic Doppler current profiler (ADCP) and CT-sensor data used for analysis of the water column. The estimated location of the vehicle is sent to the surface for mapping purposes and to aid in human operation of the vehicle.
