Fifty percent of the United States of America is underneath the ocean. And we have better maps of Mars than those areas.

The deep sea is the largest museum on earth, it contains more history than all the museums on land combined, and yet we're only now penetrating it.

Everyone is an explorer. How could you possibly live your life looking at a door and not open it?

Remember to always dream. More importantly, work hard to make those dreams come true and never give up.

The Titanic will protect itself.
