Available in PDF, EPUB and Kindle. Book excerpt: Density and air bubble pressure data obtained from ice cores from Site 2, Greenland, are analyzed to determine porosity at the pore close-off level, which is found to have a very small standard deviation. A theory of densification of bubbly ice is developed on the simple assumption that the rate of decrease in porosity is proportional to porosity and also proportional to the difference between absolute load pressure and air bubble pressure. The theory is remarkable in that it has led to derivation of a useful equation for approximating the value of the integral exp t to the m power (dt) for m> 0. (Author).
