Abstract: Polar sea ice is an important component of the global climate system, and has a great impact on polar expeditions. Using binary images of ice and water with supervised classification by MODIS L1B data, we analyzed seasonal and interannual variations in sea ice around Zhongshan Station between 2000 and 2014, combined with Landsat images and voyage data for an icebreaker (MV Xuelong) between 2007–2012. We demonstrate that for that area surrounding Zhongshan Station between 2000 and 2014, interannual variation in sea ice was consistent, and the seasonal variation of sea ice between August and March was significant. The area of sea ice reached a maximum in late September or early October, and a minimum in mid to late February. The arrival time of Xuelong at Zhongshan Station was consistent with the initial stage of sea ice melt, and the track characteristics of Xuelong closely related to the distribution of sea ice.
