Current measurements below the ice in Eclipse Sound

Velocity and direction of the current under the sea ice of the EcIipse Sound between Baffin lsland and Bylot Island were measured with specially developed devices and registered on a recorder. During the period of registration (May-June 1972) an easterly current of 5-7 cm/s superimposed by tidal and local influences (max. 12 cm/s) was found. In addition , measurements of friction between steelcone surfaces und corresponding conical ice bores are reported on. The plotted results show the influence of ice-temperature, surface quality and in some cases the influence of time.
