The bottom of the sea, that unknown area

The seabed is the least known area on Earth. Thanks to advances in technology, satellites and, above all, robots, have made it possible to take a fairly accurate picture of the seabed, but due to the lack of a succession of data, its evolution is still unknown. In any case, there are more and more plans to exploit the wealth that hides it. We went to the University of the Basque Country (UPV/EHU) for instructions.
