SCATTERING CHANGES IN THE DIELECTRIC AND PROPERTIES OF YOUNG SNOW-COVERED
ABSTRACT. Observations of the physical properties of the snow cover and underlying young fast ice in Resolute Passage, N.W.T., Canada, were made during the winter of 1982. Detailed measurements of snow density, and ice and snow temperatures, salinities, and brine volumes were made over a period of 4...
