Profiler

The Wave Profiler has evolved from ASL's Ice Profiler, an upward looking sonar instrument successfully used for measurements of ice keel drafts.

Features and Benefits

• Operational in depths up to 225 meters
• Competitively priced
• Robust, easily deployable design
• Excellent horizontal resolution using a high frequency (420 Khz) transducer with narrow (1.8 degree) beam width
• Immense data capacity and integrity capability provided by on-board flash E-PROM data storage (64 Megabytes)
• Ability to measure instrument tilt with an accuracy of +/- 0.5 degrees
• Provides very linear sensor characteristics eliminating the challenge of errors in tracking steep waves or very long swell-waves.
• Longterm power supply provided with an Alkaline D cell battery pack
• Includes software for computation of significant wave height, peak periods and autospectral.
• Optional serial data output available for real time monitoring via underwater acoustic modem.

Applications

• Siting, environmental studies and onsite monitoring of Off-shore Oil Platforms
• Dredging & Sediment Transport studies
• Design of Coastal Structures
• Research oceanography
• Bridges & Causeways
