The ocean floor is vast. The planet’s five ocean basins cover 71 per cent of the earth’s surface. And although we actually have mapped it, that map is distinctly low-res, according to an article in The Conversation. In fact, it’s less detailed than our maps of Mars, the Moon and Venus! That’s because all that pesky water gets in the way of mapping tools. But… oceanographers are working on it.
