Outline of Final Research Achievements

In order to understand the mechanism for precipitation of ikaite crystals in sea ice, tank and field experiments were examined. Precipitation of ikaite crystals was depended on the physics-chemical properties of seawater. In addition, the amount of ikaite crystals increased with increasing the elapsed time of the freezing. Based on tank and field experiments, we understood the mechanism for precipitation of ikaite crystals in sea ice.
