Abstract

The presence of sea ice in the polar region plays an important role in the global climate system, and it is therefore important to understand the characteristics on the temperature and salinity in growing process of sea ice. The objective of our study is to investigate characteristics of the temperature and the concentrations of salt under the ice conditions of grease ice and grease-pancake ice in wave fields. We used a wave tank installed in a cold room and measured the surface temperature, the water temperature, salinity, and ice thickness. As a result, it was found that the ice thickness and salinity rapidly increase when the water temperature became less than minus 2.2 degree. The grease ice condition showed the strong tendency than the pancake ice condition.
