Mechanical properties of ice at Norströmsgrund
In March 2003, level ice with a thickness of 59 cm was sampled from an ice floe close to the lighthouse Norströmsgrund. Large pressure ridges were surrounding the floe, which had a diameter of about 60 meters. A total of 12 large ice cores with a diameter of 200 mm were drilled out along two rows, w...
