The size and thickness of the Antarctic ice sheet acts as a barometer for global health but figuring out exactly how much frozen water is sitting atop the southern pole is difficult. Satellite results are often obscured by layers of snow and ice core boring requires people to brave the extreme cold to collect them. But with this self-guided sonar sub, researchers can collect accurate ice information without ever getting off the boat.
