STRUCTURAL CONTROL OF THE VERTICAL VARIATION OF THE STRENGTH OF SEA AND SALT ICE
The vertical variation in the strength of sea ice was studied by using data from NaCl ice which shows a structural similarity to sea ice and has straightforward phase relations. Measurements show that the plate spacing is a linear function of the sixth root of the distance below the upper ice surfac...

The vertical variation in the strength of sea ice was studied by using data from NaCl ice which shows a structural similarity to sea ice and has straightforward phase relations. Measurements show that the plate spacing is a linear function of the sixth root of the distance below the upper ice surface (z). Available values of the same parameter for natural sea ice are in good agreement with this relation. Equations giving the dependence of the ring-tensile strength of the ice on z were developed. It is demonstrated that in NaCl ice sheets the systematic increase in the plate width with depth produces significant changes in the ring-tensile strength of the ice. Field tests previously performed indicate that similar relations hold for sea ice. |
