| Definition | An upward-looking sonar device which can be mounted on lake, river or ocean floors to measure ice draft for monitoring of ice dynamics in shallow water environments. Ice thickness is measured in real-time using an acoustic transducer, tilt sensor, high-precision pressure sensor and temperature sensor, all providing suitably high resolution for shallow water measurements. The instrument can be operated in an internal recording mode with a connection to an underwater battery pack for power, or with RS-422 serial output for real-time operation using an underwater cable which also allows for external power. The SWIP has a storage capacity up to 16 Gb, an operating frequency of either 542 kHz (standard) or 235 kHz (optional), a half-beam width of 3 degrees (standard) or 5.5 degrees (optional), a sampling rate of up to 2 Hz, and a maximum range of 20 metres. The tilt sensor has a range -20 to +20 degrees, an accuracy -0.5 to +0.5 and a precision of 0.01 degrees. | ||
