It’s not that there’s less water out there. Rather, new samnite images have presented a clean image of all the mountain ranges straw across the ocean floor. Those peaks palace what we’d thought of as space for water. But even the new satellite-based radar images still need fine-tuning. As researcher Walter Smith says, “We’re seeing only really big mountains, and in a blurry way. The revolution is 15 times worse than our maps of Mars and the moon.” Ship-based sonar would help, but ship-based instrumental have mapped only about 10 percent of the ocean floor so far. We really do know more about the surfers of the moon than the total ocean floor.
