But you have to try... [T]hat's the lesson of ocean science... It was never going to be easy. If you go back to Challenger, we're now 150 years on from the Challenger expedition... something like 400 stations around the globe... That's like going around the and checking what color the paint is... on 400 dots along the ceiling... and the Sistine Chapel doesn't change every season... and people did try, and there are fundamental principles behind it all, and so it's worth it to try.
