内容記述 |
Microscopic observations of air bubbles and air-hydrate crystals included in the Vostok ice cores, Antarctica, revealed that badly fractured ices were observed in the ice cores having high concentration of air bubbles. They also showed that the transformation of air bubbles to air-hydrate crystals reduced the chance of ice core fracture. In this paper, we suggest a fracture model of an ice core including air bubbles to discuss the depth dependence of ice core brittleness. |
