Comparison of the strength of iceberg and other freshwater ice and the effect of temperature
Based on literature results, the temperature of an iceberg around the Grand Banks of Newfoundland is shown to vary from -2°C at the surface to approximately -20°C at depth. This temperature variation affects the strength of the ice. The strength of iceberg ice is shown to be 1.7 times less than othe...
