Title: Properties of Hummocked Ice in Transition Zone between Fast Ice and Pack Ice, Labrador
Abstract: This paper discusses property measurements made at four sites in a hummocked area of ice about 40 km east of Nain, Labrador. The measurements were made in April, when the ice thickness ranged from 0.99 to 2.20 m. The ice at the four sites was isothermal at near melting temperatures throughout its full thickness, with slightly colder temperatures at the top ice surface. The ice salinity ranged from near zero in the top ice, to 4 to 5% towards the interior of the ice, and upwards of 8% in the bottom ice. In situ borehole strengths of the hummocked ice ranged from 5.3 to 10.6 MPa at the top ice surface, and near zero to 5.5 MPa at the bottom ice surface. The borehole strength in the interior regions of ice ranged from 9.8 to 14.9 MPa.
