A review 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 GrandBanks of Newfoundland is shown to vary from about 0°C at the water-ice interface to approximately -20°C in the interior. This temperature variation affects the strength of the ice. Are view of the strength of iceberg ice show...
