That means that I use radar to study glaciers and ice sheets.

So today, I want to talk to you about why it's so hard to put good numbers on sea level rise, and why I believe that by changing the way we think about radar technology and earth-science education, we can get much better at it.

I said in the beginning that I was a radio glaciologist, and the reason that that's a thing is that airborne ice-penetrating radar is the main tool we have to see inside of ice sheets.

These are used to transmit radar signals down into the ice.

While this is happening, scientists and engineers are on the airplane for eight hours at a stretch, making sure that the radar's working.

And there are sophisticated, interesting, electromagnetic reasons for that, but let's say for now that ice is basically the perfect target for radar, and radar is basically the perfect tool to study ice sheets.

Now, we're working on that, because it turns out that the very first radar observations of Antarctica were collected using 35 millimeter optical film.

There are these recent ground-based radar systems that stay in one spot.

We can choose between good spatial coverage with airborne radar sounding and good temporal coverage in one spot with ground-based sounding.

Well, for existing radar systems, the biggest driver of cost is the power required to transmit the radar signal itself.

So, actually, one of the most exciting things my group is doing right now is trying to use the radio emissions from the sun as a type of radar signal.

And defense radars use TV signals and radio signals all the time, so they don't have to transmit a signal of radar and give away their position.

Those earlier radar systems I talked about were developed by experienced engineers over the course of years at national facilities with expensive specialized equipment.

But the recent developments in software-defined radio, rapid fabrication and the maker movement, make it so that it's possible for a team of teenagers working in my lab over the course of a handful of months to build a prototype radar.

And by teaching engineering students to think like earth scientists and earth-science students who can think like engineers, my lab is building an environment in which we can build custom radar sensors for each problem at hand, that are optimized for low cost and high performance for that problem.

And if you're a radar, that's a really bad job.

He said, "But that's if you're a radar.

So we didn't use a radar; we built a black box that was looking for electrical signals, electronic communication.

In the Second World War, too, the existence of solar radiation was demonstrated by studies of interference that was detected by the radar stations of Great Britain.

Now if you think about it, in the age before GPS and radar, that was obviously a really difficult problem.

It completely passes below the radar screen.

And maybe the hardest part about my life ending is that I learned something hard about myself, and that was that, as much as I would be frustrated about not being able to get my work out to the world, there was a part of me that was working very hard to engineer staying small, staying right under the radar.

Let me get you our weather satellite radar.

All of a sudden your GPS readout goes blank, and now it's just you and the fog and whatever you can pull off the radar system if you remember how to work it.
