"I've looked at basic bubble physics, and optics... the dynamics of what bubbles do underneath waves, and particularly, sensing them in very difficult conditions like that big storm. ...Acoustical and optical devices for detecting bubbles... just under... [Y]ou're interested in the top meter, but the top meter is going up and down, or in the case by 10 meters. So it's not an easy place to get to. But that kind of challenge, studying bubbles in difficult situations... in the ocean, that's what I do now."
