Ice-sonar deployment and corrected draft processing using IPS6, vehicle IPS-Rover and shallow-water SWIP configurations with scientific analysis.
Technical detail
Core features
IPS6 420 kHz; stated 240 m ice/310 m water acoustic range and corrected draft accuracy
IPS-Rover vehicle electronics/transducer package with integration maturity limits
SWIP shallow-water 20 m acoustic range with mounting/tilt/impact dependencies
Deployment/recovery, pressure/tilt/sound-speed correction and ice statistics
Ice profiling
Ice draft
Oceanographic analysis
Use & integration
Recorded applications
Underwater ice-draft measurement and ice-engineering analysis
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Historical IPS5 field use and ASL processing are independently documented by NOAA. IPS6 numerical specifications remain supplier claims; current IPS6/Rover/SWIP configurations and vehicle qualification require separate evaluation. Draft is submerged keel depth, not total ice thickness.
Commercial availability
Specify sonar/pressure/housing limits, mooring or vehicle interfaces, power/sampling, tilt/impact risks and atmospheric/sound-speed/density corrections. Instrument endurance does not establish vehicle endurance or uncorrected draft accuracy.
