Abstract
Two methods have been used to measure the full scale deflection of ice by the operation of the icebreaker, CCGS Sir John Franklin. The data shows consistency and indicate that three types of disturbances are caused by the operation of the icebreaker in water with a .5m ice cover. One type, long period water/ice waves(T~5s) caused by jamming of the ice sheet near the ship's maximum beam, may be associated with reports of structural damage of icebreakers that occurs in the vicinity of the `shoulder' of the bow.
