I set out to learn. I went around Scripps... I knocked on people's doors and I said "Hello, I'm a physicist. ...I'm learning about the ocean. If you've got a book you would recommend..." and people recommended books to me... [O]ne of them was Jacques Cousteau's Silent World and a whole bunch of others... Once I knew I wanted to learn, I was in exactly the right place to begin that journey.

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.
The day they carried... [the surface following buoy] down to the beach... and I had never thought about what really might be underneath [the ocean]... [T]hen I understood the context for them and... became an ocean scientist by the back door. ...Then I had opportunities to go to sea and I continued the research...
So after I finished my PhD I looked around for another topic, and I found bubbles... [T]hat... took me to Scripps, to the lab of Grant Deane and he... showed me the ocean... indirectly... I was in that lab. I had these experiments on bubbles. They involved things I understood, s and tanks and... s... [T]here was this frame by the door... and after three weeks they all started fussing around it, and I realized this thing, which I now know is just a surface following buoy, was their gateway to another world.
It's not a linear path. I did my PhD... in experimental explosion physics... I was interested in the , which was much harder then than it is now. This was before CCDs and CMOS sensors were built into things like high-speed cameras... [Y]ou had to do it the old-school way. ...[I]t was interesting and challenging and I liked building that kind of experiment. Looking at small things that were too quick... to see directly. But I never wanted to do [explosion physics]...
We know how that graph goes... Wind speed... along the x-axis, some measure of gas flux... along the y-axis, and we knew at the time that the graph only went so far to the right... [W]e were putting dots... on the graph that had not been there before... So there's that added thing of being there with the right equipment at the right time to... measure something that has not been measured directly before...
[W]e have all these dry numbers and significant wave height is one of them... [W]atching what it really means for a significant wave height to be 10 meters and thinking about how small that is compared to the depth of the ocean... It's like... having a swimming pool and... blowing tiny ripples across the top. ...Being in that situation was... fascinating and fun... I wouldn't want to do it every day, but it was... a special experience.
