Newly discovered lake may hold secret to Antarctic icesheet's rise and fall utaustin
The Princess Elizabeth Land sector of the East Antarctic Ice Sheet is a significant reservoir of grounded ice and is adjacent to regions that experienced great change during Quaternary glacial cycles and Pliocene warm episodes. The existence of an extensive subglacial water system in Princess Elizabeth Land bears the potential to significantly impact the thermal and kinematic conditions of the overlying ice sheet.
The inversion results suggest that LSE is located along a compressional geologic boundary, which provides reference for future characterization of the geologic and tectonic context of this region. We estimate LSE to be ~42 km in length and 370 kmin area, making it one of the largest subglacial lakes in Antarctica.
