It's unexplainable. I'm no, I'm hasten fouled. This week we're going deep underwater.

The vast darkness of the ocean. But also the surprising light coming from down there.

Reporter Bird Pinkerton has the story of one scientist chasing after that light.

About the extraordinary things she's discovered. But also about all the new questions she's revealed along the way.

Even as a little kid, Edie Wooder knew she wanted to be an adventure.

I had visions of being some kind of swashbuckling superhero, the female version of Zorro.

But then unlike most Adreamers, Edie actually became a swashbuckling superhero,

also known as a marine biologist. In 1984, she was working with a researcher who wanted to move away from studying animals pulled up in nets

and instead explore the ocean through diving. And that is how she found herself on a research vessel

off the coast of California, climbing into this special diving suit known as a wasp.

It's called wasp because somebody thought it looked like the insect. It's got this bubble head

and a yellow tubular body and it's got Michelin man arms with claws on the end.

The suit was going to let her see animals in the deep ocean,

sort of up close in personal, without being crushed by all the pressure down there.

So Edie got inside and then she was lowered off the back of the boat.

As you pass from air to water, everything changes. The colors all change.
