Antarctica Has Over 300 Subglacial Lakes
While finding one of these subglacial lakes would certainly be extraordinary, as of 2018, researchers had identified 379 of them! What this means is that they may be much more ordinary than scientists had initially thought, and estimates say that we are sure to discover many, many more.
Scientists have been finding the lakes by using radiography; they discovered the first one in 1970. The largest known subglacial lake is Lake Vostok; it is hundreds of meters deep, 50 kilometers across, and 240 kilometers long! Some areas have higher concentrations of lakes because of their unique geography, which is more conducive to lake formation.
