Among the projects of the scientific program of the F. S. Polarstern expedition of May 1984 along the coast of Labrador, Canada, was the measurement of the kinetic friction factor between various surfaces and sea ice samples collected at the site of the ship trials. The surfaces included a steel sheet coated with Inerta 160 to represent the ship hull, and base steel sheets of two roughnesses. The latter had previously been tested at CRREL with urea-doped ice, which is used as model ice in tests of icebreakers and other structures (Forland and Tatinclaux 1984). A friction test table was specially constructed by the Hamburgische Schiffbau- Versuchsanstalt (HSVA), the organization leading the expedition, and was instrumented on board the Polarstern. The ice samples used in the friction tests were cut from two large ice blocks gathered at the trials site, primarily Hebron Fjord; samples from the same blocks were used in two other projects, which were studies of ice structures (Gow 1984) and ice strength properties (Timco and Frederking, in prep.).
