| Definition | The ASL Environmental Sciences ISP4 is an upward looking sonar device for measuring ice keel drafts. Distance between the instrument and ice keel 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 difference. It has a depth range of 175 metres in ice or 225 metres in water and a precision of 0.05 metres. | |
