Ice cover movements and stresses were measured near Adams Island from November 1984 to May 1985. The average horizontal movement rate was 0.1 m/day. Global compressive and tensile strains were less than 1 and 4%, respectively. Strain rates (measured over 1 – 2 month periods) were of the order of 10 −9 s −1 . Maximum stresses and forces in the ice cover were 500 kPa and 400 kN/m, respectively. Key words: ice movements, ice stresses, ice forces, Canadian Arctic Ocean.
