Here's something you may not know. We have more information about the surface of Mars than we do about our ocean floors. Believe it or not, Mars is easier to photograph.
As a result there is still a lot about our oceans we don't know. That's why there are so many mysterious things about our oceans. We need to further study them, you know, once we are done with Mars.
And I hope we get to that point soon, because I have a lot of questions after reading some of these stories.
