Abstract:The sea-ice mainly refers to that floats on the surface of the sea.They are affected by the wind and the flow.Sea-ice is considered to be not only a kind of serious natural disaster,at the same time in the icy water of resources development,the physical parameters of the sea ice is also considered an important environmental parameters that the sea-ice thickness is the most important.In order to monitor and study the sea-ice thickness change and disappear,people have taken a lot of methods to obtain the thickness of the ice. This paper summarizes the method of measuring ice thickness representative at home and abroad in recent years. There is also the error analysis about each method.
