Figure 2
DEI images of ice core samples. These core samples showing three dimensions were drilled from depths of (a) 2175.8 m and (b) 575.8 m. The internal parts of the images were made transparent to show the inclusions more clearly. The cross sections in (a) and (b), which are cut through almost at the centre of each ice core, are shown in (c) and (d), respectively. Here, green regions in the images indicate areas where the densities are higher than that of the surrounding hexagonal ice, which corresponds to air hydrate. Also, red regions in the images indicate areas where the densities are lower than that of the surrounding hexagonal ice, which correspond to air bubbles. |
