Includes bibliographical references (page 18). "A profiling drogue has been developed to drift under an ice jam and report the thickness of ice above its track. The development involved mathematical modelling, scale modelling and full-scale trials in a tow tank to determine optimum shape and balancing forces. In 1990, successful field trials were done with ice Jams in the Thames River, Ontario and the Restigouche River, New Brunswick"--Abstract.
