The mission of this International Polar Year ( IPY ) project is to uncover secrets of the enigmatic Gamburtsev subglacial mountains that are buried by up to4 km of ice ;

The formation of subglacial lakes results mainly from geothermal flux and partially from heat produced from basal sliding and internal ice deformation which raise the temperature of the basal ice to melting point and gradually melt the ice .

Generally the influence of subglacial topography to ice surface is not significant in addition to the location of 900 km where ice surface uplifts evidently caused by rising of subglacial topography .
