Theoretical studies on densification and relaxation of bubby glacier ice
This paper presents a brief review of the authors' earlier research on polar ice density modeling carried out and published (in the main) during 1983-1989 in Russia. A theoretical approach to macrocontinuum description of bubbly ice densification (expansion) on the basis of averaging asymptotic...
