An experimental study on the spectral characteristics of one year‐old sea ice in the Bohai Sea, China.

Sample series of clean regular‐shaped ice representative of thermal interaction processes only were gathered in a controlled experiment on ice floes in China's Bohai Sea. Based on these samples, spectral characteristics for one‐year‐old sea ice were measured and analyzed. The same experiments were then performed for ice samples with two normal impurities and the results compared against those of clean samples. Along with increasing thickness, the reflectance of clean regular‐shaped ice rises in the form of a ladder within the visible light range. While flat regular‐shaped ice is covered by thaws snow and/or mixed with mud and sand, the trend of increasing reflection with thickness of clean regular‐shaped ice is disordered.
