There’s a whole lot of ocean on this planet, and we don’t have much of an idea what’s at the bottom of most of it. That could change with the craft and techniques created during the Ocean Discovery Xprize[1], which had teams competing to map the sea floor quickly, precisely and autonomously. The winner just took home $4 million.
A map of the ocean would be valuable in and of itself, of course, but any technology used to do so could be applied in many other ways, and who knows what potential biological or medical discoveries hide in some nook or cranny a few thousand fathoms below the surface?
The prize, sponsored by Shell, started back in 2015[2]. The goal was, ultimately, to create a system that could map hundreds of square kilometers of the sea floor at a five-meter resolution in less than a day — oh, and everything has to fit in a shipping container. For reference, existing methods do nothing like this, and are tremendously costly.
But as is usually the case with this type of competition, the difficulty did not discourage the competitors — it only spurred them on. Since 2015, then, the teams have been working on their systems and traveling all over the world to test them.
Originally the teams were to test in Puerto Rico, but after the devastating hurricane season of 2017, the whole operation was moved to the Greek coast. Ultimately after the finalists were selected, they deployed their craft in the waters off Kalamata and told them to get mapping.

“It was a very arduous and audacious challenge,” said Jyotika Virmani, who led the program. “The test itself was...
