More Than 200 Meters of Lake Ice Above Subglacial Lake Vostok, Antarctica
Science, 1999Isotope studies show that the Vostok ice core consists of ice refrozen from Lake Vostok water, from 3539 meters below the surface of the Antarctic ice sheet to its bottom at about 3750 meters. Additional evidence comes from the total gas content, crystal size, and electrical conductivity of the ice.

The ice topography over subglacial lakes
Cold Regions Science and Technology, 1990Abstract A model is developed which relates the ice-surface topography above subglacial lakes to the length l of bed transition regions bordering the lake where the effect of the presence of the lake causes a reduction in basal shear stress. The model is applied to four representative regions of an ice sheet.

Subglacial Lake McGregor, south-central Alberta, Canada
Sedimentary Geology, 2003Abstract It is proposed that a lake, here named “Subglacial Lake McGregor”, existed beneath the Laurentide Ice Sheet at, or near, the last glacial maximum. The lake resided in the ancient buried McGregor and Tee Pee preglacial valleys, which are now mostly filled with glacigenic deposits.
