Abstract: The formation and changes of supraglacial lakes are important indicators of the melting of the Antarctic ice sheet, and hence are of great importance to the global climate system. In this study, we monitored the evolution of the supraglacial lakes on the Polar Record Glacier (PRG) in East Antarctica between 2000 and 2017 using Landsat and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images. The interannual and seasonal variations of lake area, depth and volume were examined. In addition, the relationships between supraglacial lakes, and air temperature, elevation and topography were analyzed using temperature data from Zhongshan Station and Advanced Land Observing Satellite Digital Elevation Model (ALOS DEM). The results show that each year, the supraglacial lakes on the PRG appeared prior to December, and entered the rapid growth stage in December. Lake area, depth, and volume peaked in middle and late January of the following year. Lake area, depth, and volume were consistent, and their changes were closely related to positive degree days. Ninety two percent of the lakes are in the region below an elevation of 200 m. In this region, supraglacial lakes form easily where ice flow lines converge or are in high density
