Abstract: Freeze-up processes in the North Saskatchewan River, Edmonton, AB, Canada were monitored during the 2009/10 freeze-up season. Instrumentation used for monitoring included the following: a high (545 kHz) and low (235 kHz) frequency Shallow Water Ice Profiling Sonars (SWIPS), 2 MHz AquaDopp current profiler, underwater video camera, and a real-time monitoring station that recorded and transmitted digital images of river ice conditions and air and water temperatures. Different river ice phenomena were distinguished and recorded using the SWIPS acoustic signal. Preliminary linkages between meteorological and hydraulic factors affecting river ice processes are presented and discussed for some selected events of interest. The SWIPS proved to be a very effective instrument for studying the properties of suspended frazil ice and frazil pans.
