NUTCRACKERS OPENING ARCTIC ICE SECRETS

Notes instruments to measure the force exerted by moving ice on fixed structures, designed by Imperial Oil Company engineers, as being tested offshore from Kognallit Bay, near Tuktoyaktuk. They consist of two vertical cylinders 16 feet long and 30 in diam, hinged at the bottom. Hydraulic jacks on top of the legs push them open against the ice until it fractures. The feasibility of the instruments is briefly discussed relative to the ice in shallow Mackenzie Delta region waters.
