Ice Profiling Sonar (IPS)


An upward-looking sonar device, mounted on the ocean floor to accurately measure ice draft.

When you need to:

  • Estimate ice forces for design of offshore platforms and operational planning
  • Determine the extreme thickness of ice for pipeline installations
  • Examine in detail the underside of sea-ice
  • Understand the dynamics and thermodynamics of the sea ice regime for scientific research.
  • Climate change studies

    You can count on the Ice Profiling Sonar (IPS), for reliable accurate measurements of ice thickness and keel drafts.
