Sea ice properties on the USCGC Healy ice trials
During the USCGC Healy ice trials in Baffin Bay in April/May 2000, the sea ice thickness and strength, as well as the snow thickness, were measured. The thickness of the ice was measured. The thickness of the ice was measured by augering, by an electromagnetic (EM) method, from cores, and with an Ov...

The thickness of the ice was measured. The thickness of the ice was measured by augering, by an electromagnetic (EM) method, from cores, and with an Over-the-Side Video (OTSV). Good agreement was found from these methods in the first year ice, but less good for the two cores of multi-year ice. The snow thickness was measured by point survey measurements and from the OTSV. The OTSV method gave snow thicknesses consistently greater than the point measurement. These different methods are described and the results obtained are discussed. Sea ice strength was determined by drilling cores either by hand or with the RapidCore equipment, measuring temperature, salinity and density, and then calculating flexural strength. The mean strength of the first year ice was 315 kPa (46 psi) and the mean strength of two multi-year cores was 714 kPa (104 psi).
