A new nature film uses microscopes to reveal climate secrets

Ariel Waldman’s – In her six-part docuseries “Life Unearthed,” Ariel Waldman brings a soil-science team to Antarctica’s dry valleys and to North American prairies, filming microscopic life in situ with microscopes, a macro probe lens, drones, and custom camera rigs. The message

She’s standing alone in a landscape that looks like it belongs to another world: dry. dusty ice on jagged mountains. rock shards underfoot. and a hazy white sky where the sun appears very far away. Ariel Waldman smiles anyway. “I’m in Antarctica’s dry valleys,” she explains—an expanse of deep-brown earth between frozen mountains and ancient glaciers.

It’s not a mission to another planet. But in her new six-episode docuseries. Life Unearthed. Waldman is trying to make Earth feel alien in the way it really can—through what’s hidden inside it. The series. which is available on PBS and YouTube. follows a soil-science team in Antarctica’s southernmost continent while she builds her own toolbox for seeing life at the scale most people never notice.

Waldman brought microscopes, including a macro probe lens designed to capture depth of field when shooting minute landscapes. She also brought a drone and several complicated camera mounts. With those tools. she records “the microscopic jungle” that lurks in the planet’s crust—microbial mats in Antarctica’s desert valleys. and tiny animals across other ecosystems—while also filming herself at work. creating a running portrait of what it’s like to study an environment that’s changing quickly. “and sometimes violently. ” as climate change reshapes it.

The series moves from the seemingly lifeless dry valleys of Antarctica to the bubbling wetlands of North American prairies. There. Waldman introduces viewers to nematodes. rotifers. and tardigrades—tiny creatures that shape and nourish ecosystems while remaining invisible to the naked eye. The docuseries doesn’t just claim they’re important; Waldman films them in place. turning size and invisibility into something you can actually watch.

Perhaps the boldest part is how much of it she did on her own. Waldman filmed her journey entirely on her own, alongside a soil-science team in the field. She also serves as the official curator of the San Francisco Microscopical Society. and the project carries a personal mission: normalise the idea that people should look at the dirt through microscopes as often as they peer through telescopes at the sky.

Waldman told me she’s motivated by urgency, and by a simple barrier to discovery. “If you want to do a nature documentary in [the dry valleys] of Antarctica. you need microscopes to see the animals that exist there. ” she said. The same logic applies to the prairies, where the vast majority of biomass lurks deep in the soggy ground.

When people get the chance to see what lives there, she argues, they gain confidence—enough, she hopes, to advocate for conservation. “When people can see life in all its diversity, she believes, we become more confident about advocating for its conservation,” she said.

The idea is also stitched into how she talks about life beyond Earth. Waldman’s point is that if you’re searching for living things on other planets or moons. “our best guess is that we would find something microscopic.” In Life Unearthed. she films tardigrades—also known as water bears—under the microscope. watching them wiggle their puffy legs and bump into plant cells. She notes that these animals can survive in the extreme cold of Antarctica and the sweltering prairies. and even the vacuum of space. For Waldman, that survival doesn’t just make tardigrades compelling. It suggests the kinds of characters we might find beyond the safe envelope of our atmosphere.

I first met Waldman when she was working with NASA and running Spacehack. an organisation that connects citizen scientists with space-exploration projects. She introduced me to CubeSat, a group of people who launch DIY satellites into orbit. Later. she helped create Science Hack Day. a global event where scientists and enthusiasts collaborate on projects ranging from data gathering to software development. Since then. we’ve stayed in touch. and I’ve watched her build a career that blends science. art. and community organising—exactly the blend she’s now bringing to Earth’s smallest life.

The day before she left for Antarctica, her biggest worry wasn’t weather or equipment readiness. It was something more basic: how she would get as much equipment as possible into her suitcases.

Waldman’s academic background is in graphic design, not traditional field biology. Still, she doesn’t want to research the planet quietly. She wants to show it to people—so she’s encouraging viewers to try the same door into discovery. She talks about getting a cheap microscope and “just throw things under it. ” an invitation that feels less like a gimmick and more like a philosophy.

Scale is central to that philosophy, too. Waldman has been influenced by the famous 1977 Eames short film Powers of Ten. which turns understanding into a series of jumps—closer. farther. bigger. smaller. In her work, scale is the bridge between worlds: drones for aerial views, microscopes for the unseen. And when she’s chasing prairie crayfish in their underground burrows. she uses a camera on a long wire designed for snaking into clogged pipes.

“Humans are both very small in the universe and very large in the universe, depending on your perspective,” she mused. “So much of life is ‘virtually invisible to us without technology’.”

The docuseries lands on a hope that feels grounded rather than grand: Life Unearthed should push more people to pick up a microscope and look at the invisible wildlife beneath their feet. To understand the true wonder of nature. Waldman seems to believe. you have to see it first—at whatever scale it’s willing to reveal itself.

And in Antarctica’s dry valleys, with deep-brown earth stretching out between frozen mountains and ancient glaciers, that belief takes a vivid form: a researcher’s smile, a suitcase packed with cameras, and a world that only starts to make sense once you’re ready to look much smaller.
