THE DEVELOPMENT OF THERMISTOR CHAIN BUOYS FOR USE IN ICE INFESTED WATERS

The use of temperature profiles gathered in near real-time can greatly increase the accuracy and timeliness of forecasts such as the prediction of freeze-up. This paper describes the development of ARGOS-based thermistor chain buoys for deployment in the Gulf of St. Lawrence up to and beyond the appearance of ice. The buoys use a slack, buoyant mooring system that allows them to remain in place until the arrival of ice cuts them free to drift with the ice pack while continuing to provide uninterrupted data transmission. Data recovered from field operations are presented and analyzed.
