Abstract: Magnetostrictive displacement sensor has the characteristics of high precision, high reliability and multi-position detecting. Basing on the principle of this sensor and the special requirement of environmental suitability, an ice monitor thickness apparatus is developed and it can observe the fine process of ice thickness variations with large temporal and spatial resolutions. The apparatus has been used to measure sea ice thickness variation at Zhong Shan Station, Eastern Antarctica for about 6 months, with the precision of ±2mm, up to an hourly level in temporal resolution. The data give a powerful support to the development and modification of ice mass forecast models. This apparatus satisfies the needs of obtaining ice thickness with high precision for ice science and ice engineering.
