| Abstract | Pack-ice driving forces are synonymous with the limiting forces that can be transmitted through pack ice. Knowledge of this topic is important in relation to: ice loads on structures (the limiting driving force approach); ice motion modelling and forecasting; arctic ship routing. Until recently, limiting pack-ice forces had been speculated upon but never measured. This paper describes a pilot experiment to measure typical values for pack-ice driving forces across a width of several kilometres in the southern Beaufort Sea. In-situ ice pressure sensors were installed near the middle of a multi-year floe. The floe was subject to converging ice conditions and pressure ridging occurred around it. Corresponding compressive ice stresses in the floe were measured from which the average pack-ice forces associated with the observed ridging could be inferred. The paper describes the background to the project, the general approach, the equipment used, and the results obtained. |
