Abstract:
The theory of snow densification is further developed on the basis of an exponential relation between viscosity and density. A linear relation between load-stress and strain rate is not valid for high stresses, and is replaced by a hyperbolic sine function. An empirical function is given for the temperature cycle correction. Two equations are derived for calculating depthdensity curves with computers, and a simplified one for use with desk calculators. InstructionsARE GIVEN FOR DETERMINATION OF FUNCTION PARAMETERS FROM FIELD DATA. Four depth-density curves for Greenland and Antarctic locations are computed and graphed to show that the theory is useful. Author
