I am an underwater explorer, not a treasure hunter.

There's probably more history now preserved underwater than in all the museums of the world combined. And there's no law governing that history. It's finders keepers.

I'm a geophysicist and all my earth science books when I was a student, I had to give the wrong answer to get an A. We used to ridicule continental drift. It was something we laughed at. We learned of Marshall Kay's geosynclinal cycle, which is a bunch of crap.

Well, when I was a kid, I grew up in San Diego next to the ocean. The ocean was my friend - my best friend.

Almost a quarter of our planet is a single mountain range and we didn't enter it until after Neil Armstrong and Buzz Aldrin went to the moon. So we went to the moon, played golf up there, before we went to the largest feature on our own planet.

Fifty percent of our country that we own, have all legal jurisdiction, have all rights to do whatever we want, lies beneath the sea and we have better maps of Mars than that 50 percent.

Most of the southern hemisphere is unexplored. We had more exploration ships down there during Captain Cook's time than now. It's amazing.

So, you know, I think the age of exploration is just beginning, not ending, on our planet.

I believe in just enriching the economy. And we're leaving so much on the table, 72 percent of the planet.
