Scientists recently made a terrifying new discovery under Antarctica’s Ice . Using radar technology, they discovered a massive cavity two-thirds the size of Manhattan located under the Thwaites Glacier. The cavity is thought to have been caused by melting ice, which can contribute to sea level rise. This discovery is concerning as it indicates that the glacier is melting faster than previously thought. The cavity is estimated to contain around 14 billion tons of melting ice, which is equivalent to around 0.4 millimeters of global sea level rise.

If the glacier formed on land then the missing mass could have been rock and/or soil. Which would absorb more heat from light than the ice around it. Thawing and falling to the bottom of the ocean. Here's to the time when we are capable of tracking these movements and breadcrums dropping from the bottom of glaciers as they become sea-bound
