Abstract: This report presents the results of tests of the ice friction coefficient μk carried out during the May 1984 expedition of the F.S. Polarstern off the coast of Labrador. The test surfaces were Inerta-160-coated steel plates and bare steel plates, hand roughened and sandblasted. The main findings of the studies were: 1) columnar and granular sea ice showed no significant differences in friction coefficient; 2) for columnar ice, μk was independent of ice crystal orientation with respect to test surface; 3) μk was independent of normal pressure applied on ice sample; 4) μk initially decreased with increasing relative velocity between the ice sample and the test surface and reached a steady value at higher speeds; 5) μk increased with increasing surface roughness; 6) a wetting surface exhibited a higher friction coefficient than a non-wetting surface of the same or even higher roughness average.
