Researchers plan to camp near this shallow pond for six weeks starting in December, to get detailed measurements of its liquid and explore the local area.
At the base of the Transantarctic Mountains lies a geological oddity, reports Hannah Hickey at UW News.
Don Juan Pond is one of the saltiest bodies of water on the planet, filled with a dense, syrupy brine rich in calcium chloride that can remain liquid to minus 50 degrees Celsius, far below the freezing point of water.
But the source of water and salt to this unusual pond remains a mystery — even as hints emerge that water in a similar form could exist on Mars.
A new University of Washington study uses the pond’s bizarre chemistry to pinpoint the water’s source.
