Almost had my career with them. Twice, ocean and, later, landlubber.
Never out with them though on anything useful, as crew or scientist.
If I could do all over, I would choose that path. I wouldn't want to waste my time on global warming though, since it's so obviously true. The so-called "doubt" rains monies on doubters and scientists alike. So much time and energy wasted on arguments and conjecture.
Rather, even now, the undersea network of data collection devices would be where I would want my talents. Could still do it, but no one will believe me. That's why I don't like the over-concern with academic achievement these days. And why I'm big on people's potential over credentials.
