Lake Mercer, a subglacial lake deep below the Antarctic Ice, sat untouched by humans for millennia – until now. Scientists accidentally discovered the lake in 2007, when they were examining satellite imagery of Antarctica’s ice sheet. Then on December 26, 2018, they finally reached it. To explore the 50-foot-deep subglacial lake, researchers from a project called SALSA
