Sea Ice: Part II. Estimating the Full-Scale Tensile, Flexural, and Compressive Strength of First-Year Ice
Sea-ice salinity, density, and temperature data were used to develop new methods for determining the bulk brine volume and porosity of sea-ice floes. Methods for estimating full-thickness ice sheet strength, based on large-scale field tests, are presented. The relationships among bulk sea-ice proper...
