And can you just tell us where you came from? Where'd you grow up? And maybe what were your earliest memories and interactions with science?

Yes, well, my family on my mother's side is from Baltimore, Maryland.

But we as a family unit, my mother, my father, and myself, I'm an only child, we've sort of followed my mother's trajectory in terms of her career as an instructor.

She was a speech major at Wheaton College.

So Wheaton College plays a big role in my story.

And after leaving Wheaton College, she got a series of teaching positions, met my father, continued to teach.

And we ended up moving to Saskatoon, Saskatchewan when I was five years old because of a teaching position that she got.

And maybe just start with how you got invited to join on that expedition.

Using Esri-

Esri-Software Yes So how did you make the move from being the university person to being the Esri person? Well, it was, uh, uh, I think it might've been all of the letters that I wrote to, to Jack Dangermond- Okay, yes ...

the CEO of, of Esri, as well as to, uh, other people at Esri, just telling them about how we in the ocean community are trying to use their technology and how it's, uh, it's useful and powerful, but it's coming up short because it's not three-dimensional enough.

It is not, uh, able to ingest many of the formats that we produce, uh, at sea, including bathymetric formats.

Mm-hmm.

Uh, it's not four-dimensional.

It doesn't pay enough attention to the temporal component of the data.

Yes

Let's go.

Descending in a submersible is not unlike, uh, being in a space capsule in many ways.

You're in a very small space, not enough room to, to stand up.

It was very slow and very peaceful and very calm.

And as we got to around 800 to 900 meters depth, that's when we lost light.

We were treated to a fireworks show of sorts, worms, jellyfish, angler fish.

They use bioluminescence to communicate with each other.

Okay, Dawn, just to start, how does one map the seafloor?
