A Hole Opens Up Under Antarctic Glacier -- Big Enough To Fit Two-Thirds of Manhattan
Scientists have discovered an enormous void under an Antarctic glacier, sparking concern that the ice sheet is melting faster than anyone had realized -- and spotlighting the dire threat posed by rising seas to coastal cities around the world, including New York City and Miami. From a report: The cavity under Thwaites Glacier in West Antarctica is about six miles long and 1,000 feet deep -- representing the loss of 14 billion tons of ice. It was discovered after an analysis of data collected by Italian and German satellites, as well as NASA's Operation IceBridge, a program in which aircraft equipped with ice-penetrating radar fly over polar regions to study the terrain. The discovery is described in a paper published Jan. 30 in the journal Science Advances. The researchers expected to see significant loss of ice, but the scale of the void came as a shock.Read more of this story at Slashdot.
