THEORY OF DENSIFICATION OF DRY SNOW ON HIGH POLAR GLACIERS, II
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)
