Abstract

Abstract

In order to investigate the melting process at the ice-water lateral interface and to quantify the dominant factors affecting the lateral melting rate of ice layer, an ice melting experiment was carried out in a low-temperature water tank. Simultaneous measurements of the ice bottom and surface processes and the lateral melting process of the ice layer were carried out, while the laboratory air temperature, ice temperature at different depths inside the ice samples and water temperature at different depths in open water were recorded, the relationships between different elements and their influence patterns on the lateral melting rate of ice were investigated using correlation analysis methods. The results show that the lateral melting rate at different depths inside the ice samples was slow and uniform in the early stage of melting, with an average melting rate of 0.05 mm/h. The lateral melting rate at different depths in the middle and late stages of melting increased significantly and was no longer uniform, with an average melting rate of 0.15 mm/h. The correlation coefficient of the average lateral melting rate and air temperature (r=0.82) was better than that between the average water temperature (r=0.74) and the water-ice temperature difference (r=0.48). The quantitative relationships of lateral melting rate with temperature (air temperature, water temperature) and depth were established to accurately describe the non-uniformity of the lateral melting process of ice layer. It also verifies the feasibility of conducting non-uniform lateral melting test techniques, and lays the foundation for sea ice tests that more closely resemble real Arctic conditions considering wind speed and light source conditions.
