Abstract: In the Second Chinese National Arctic Research Expedition (CHINARE) during July and August, 2003, the expedition area covered the latitude range of 72oN-80oN and the longitude range of 169oW- 150oE. A set of sea ice digital videos and photos along the investigation route was obtained by means of a digital video fixed on the side of R/V Xuelong and a digital camera fixed on the helicopter. This paper presents the methods of obtaining sea ice thickness and concentration from the digital images. And using these methods, the distribution of ice thickness and concentration along the route of CHINARE-2003 is obtained, which can provide the basic parameters for the state of sea ice characters along the investigation route and the farther research of the coupled atmosphere-sea ice-ocean model in the Arctic Region.
