What drives me is exploration with a purpose, more the classic Royal Geographical Society genre.

The fact that this chain of life existed [at volcanic vents on the seafloor] in the black cold of the deep sea and was utterly independent of sunlight - previously thought to be the font of all Earth's life - has startling ramifications. If life could flourish there, nurtured by a complex chemical process based on geothermal heat, then life could exist under similar conditions on planets far removed from the nurturing light of our parent star, the Sun.

Why are we ignoring the oceans? Why does NASA spend in one year what NOAA will spend in 1600 years? Why are we looking up? Why are we afraid of the ocean?

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

Most of the time you are growing up, people tell you what's wrong with you. Your coach tells you, your parents tell you, the teachers tell you when they grade you. I think that's very good in the early stages, because it helps you then develop skills. But at some point in your career, generally I think when you are in your teens, you look in a mirror and you have to say, despite all the bumps and warts, "I like that person I'm looking at, and let's just do our best."

Everything I'm going to present to you was not in my textbooks when I went to school ... not even in my college textbooks. I'm a geophysicist, and [in] all my Earth science books when I was a student - I had to give the wrong answer to get an A.

I think the most important thing people can do to save our planet and the human race is to empower women!
