Description
The Ice Profiling Sonar (IPS) is an example of an Upward-Looking Sonar (ULS) that provides continuous (1-2 Hz), high-resolution (1 cm vertical, ~1 m horizontal) measurement of ice draft. The IPS is typically installed on a subsurface mooring anchored to the seabed and has been used in data-logged and real-time configurations since the early 1990s. Used repeatedly over many years, the IPS has helped develop long time-series (25+ years) of Arctic ice conditions in a changing climate.
