Jessica Mejia's office looks a little different than most.

So the only way that we can get on the glacier to do our field work is we have to fly via

helicopter. Yes, Jessica is a glaciologist. She's a postdoctoral fellow at the

University of Buffalo, but her study subject is a couple thousand

miles away on the Greenland ice sheet, a frigid mass that covers around 80% of the country.

Looking out over it in southeast Greenland, it's very jagged mountains on the edge of it.

And then you see the glacier kind of cascading over these steep cliffs.

And as you keep on flying flying you fly kind of away from this whole

cracked area that's kind of steeply sloping and then you just see the horizon that's

just flat with ice.

And that is where the helicopter drops Jessica's team.

And he was like, see you in a month.

Good luck.

Their first step is to set up camp, which

means shoveling out a flat space, pitching tents, and

building a wall of snow for protection from the wind. Basically, they have to create a

space in which they can survive on this glacier that takes its name, Hellheim, from Norse mythology's

frozen world of the death.

It's almost kind of like another planet when you're out there because you are the only people out there.

You know you're very much alone, you just hear kind of the wind or if the wind dies down,

it's silent. These glaciers are melting due to climate change and that's causing sea levels to rise.
