HYDROLOGICAL DEVELOPMENT AND PHENOLOGY OF LAKES OF THE FILDES PENINSULA – ANTARCTICA: Hydrological development and phenology of lakes of the Fildes Peninsula - Antarctica
This paper evaluates the freezing and thawing dynamics of the Fildes Peninsula lakes using TerraSAR-X (TSX) images from February to April 2011, and the correlation of the open water surface area with temperature, precipitation and wind. The open water surface area was obtained from the TSX images cl...

The correlation of atmospheric air temperature with the area, determined by the Pearson and Spearman correlation method, demonstrates a significant correlation pattern in 7 of the 15 lakes, while precipitation is an important variable for the formation of open water in 11 of the 15 lakes.
