Abstract: The ridge described in Part I had a keel depth of 1.1 m and was monitored with thermistor strings for 4 weeks. The thickness of the consolidated layer was 0.2 m 19 hours after the formation and it finally became (h) 0.6–0.8 m. The oceanic heat flux during this initial phase was estimated to be roughly 2.2 kW/m. Different tests were done on ice from the consolidated layer, and the uniaxial compressive strength was 2.9–5.9 MPa, the salinity was between 2 and 5.5 ppt (similar to level ice in the area) and the density was between886 and 956 kg/m (level ice spanned from 783 to 906 kg/m).
