Created by hydrothermal activity beneath the ice?
A massive newly discovered lake may lie below the surface of the Antarctic ice sheet, according to researchers using satellite images.
Though not as large as Lake Vostok, Antarctica’s deepest and largest subsurface lake, the newly discovered lake is likely a close second, the researchers said.
“We’ve seen these strange, linear channels on the surface, and are inferring these are above massive, 1000-kilometer-long (600-mile-long) channels, and there’s a relatively large subglacial lake there too,” Martin Siegert of Imperial College London told New Scientist.
How does a huge lake form far beneath the surface of the ice?
Not by human intervention, for sure. Not by “global warming,” for sure.
That lake has to have been formed by hydrothermal activity heating the ice from below, the same hydrothermal activity that heats the world’s oceans.
