AbstractSalinity/electrical conductivity, oxygen isotope and grain structure analysis of ice cores recovered from the surface of an ice island showed the ice to be of freshwater origin. The grain structure of the ice was somewhat columnar; density ranged from 875 to 900 kg/m[3]. Seven uniaxial compression tests were done on specimens 60 mm in diameter, 110 mm to 160 mm long and oriented vertically with respect to the surface of the ice island. Compressive strengths ranged from 1.4 MPa to 3.5 MPa (at epsilon [nom] = 10[-5]s[- 1], comparable to values for iceberg ice.
