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.

The Axis war effort throughout the first half of the 1940s led to some incredible advances in submarine technology. That includes the anaerobic Walter turbine — a newfangled engine that didn't need oxygen to work. Even more incredible, these discoveries were not entirely new, but in fact more than 60 years old — the fruits of a Victorian-era engineer's labours during construction of the world's first powered submarine.
