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 in the order of 10 [-9] s [-1]. Maximum stresses and forces in the ice cover were 500 kPa and 400 kN/m, respectively. Les mouvements et les contraintes dans les couverts de glace ont été mesurés près de l'île Adams de novembre 1984 à mai 1985. La vitesse moyenne du mouvement horizontale était de 0. 1 m/jour. Les déformations globales en compression et traction étaient respectivement moins de 1 et 4%. Les vitesses de déformations mesurées au cours de périodes de 1- 2 mois étaient de l'ordre de 10 [-9] s [-1]. Les contraintes et forces maximales dans le couvert de glace étaient respectivement de 500kPa et 400 kN/m. Peer reviewed: Yes NRC publication: Yes
