Description

The ASL Environmental Sciences (e.g. IPS4 or IPS5) ice profiler is an upward looking sonar device deployed on a mooring for measuring ice keel drafts. The distance between the instrument and the bottom of the ice is measured by sonar at an operating frequency of 420 kHz with a beam width of 1.8 degrees and sampling rate of up to 2Hz. Water depth is measured by a pressure sensor and ice draft is calculated by the difference.
