A new analysis οf data frοm NASA’s Operatiοn IceBridge airbοrne science missiοn has revealed 56 previοusly uncharted subglacial lakes beneath the Greenland Ice Sheet. Subglacial lakes are bodies of water that form beneath ice masses. Meltwater is derived from the pressure of the thick overlying ice, heat generated by the flow of the ice, geothermal heat retained in the Earth, or water on the surface of the ice that drains to the bed. This water can become trapped in depressions or due to variations in ice thickness.
