Ologies with Alie Ward: Antarcticology (Antarctic Research) with Ariel Waldman – Episode Summary
Episode Overview
In this episode, Alie Ward interviews Ariel Waldman—NASA alum, National Geographic explorer, microscopist, filmmaker, and host of PBS’s "Life Unearthed." Ariel specializes in Antarctic research, focusing on the continent’s biology, ecology, and astrobiological significance. Their conversation explores the realities of living, researching, and surviving in Antarctica, as well as the unexpected beauty and drama of its smallest inhabitants.
Main Themes
- What it takes to get to Antarctica and work as a researcher, as well as daily life and survival on the continent
- Antarctica’s unique geography, geology, and role as a planetary analog (especially for Mars and icy moons)
- Microbial and microscopic life forms that dominate Antarctica’s extreme ecosystems
- Science, logistics, cultural quirks, and the future of research and tourism at the "bottom of the world"
Key Discussion Points & Insights
1. Ariel Waldman’s Path to Antarctica
- Non-traditional trajectory: Ariel started in design/art, not science, but pivoted after being inspired by a NASA documentary.
- Quote: “I realized, oh, I am valuable to science as I exist today. Had I known that I could just walk in and work for NASA…I would’ve done that long ago.” (08:09)
- Cold-emailed NASA, landed a job translating between technical and creative communities, and eventually learned of Antarctica as a space analogue.
2. Getting to Antarctica: Applications & Qualification
- Applied for the NSF Antarctic Artists and Writers grant for 5 years before acceptance.
- Quote: “I applied to that grant for five years and then I got the chance…” (08:28)
- Stringent Physical Qualification (PQ) process: Medical checks to ensure candidates won't require emergency medical evacuations.
3. Packing, Transport, and Living Logistics
- Luggage limits: 85–185 pounds per person, must include all research and survival gear.
- Travel and resupply via military aircraft—weight is carefully budgeted.
4. Life at the Research Station & the Dry Valleys
- McMurdo Station: “Small town” vibes with a dorm, cafeteria, hundreds of people. But fieldwork (the Dry Valleys) involves camping in small groups amidst Mars-like deserts.
- Quote: “My teammates would go on a 10-mile hike… sampling all these little creepy crawlies… I would go and set up for the day…really alone.” (15:03)
- Solitude: Deep isolation, but also shared mealtimes for camaraderie.
5. Personal Impact of the Antarctic Experience
- Transformative: "I no longer felt like I needed to prove myself." (15:57)
- Quote: “Going to Antarctica is really, truly a wonderful reset button…Nearly everyone…has something that’s slightly life-changing.” (15:57)
6. Antarctica’s Geography, Geology & Astrobiological Significance
- Size: Larger than US + Mexico; up to 3 miles thick in ice.
- The McMurdo Dry Valleys: Largest ice-free region, protected by mountains.
- Analog for Mars & icy moons (Europa, Enceladus): Subglacial lakes, glaciers, and rock-ice interactions mirror extraterrestrial environments.
- Quote: “All the microorganisms that are able to survive under those layers of ice…[get] their energy from the rocks.” (19:44)
7. Research: Sampling & Studying Microorganisms
- Target organisms: Tardigrades, rotifers, nematodes, cyanobacteria, microalgae (e.g., diatoms), etc.
- Drilling and sampling: Up to 3 ft into glaciers (not the deep subglacial lakes).
- Lab challenges: Filming microscopic life requires balancing slide clarity and simulating environmental conditions.
8. Extreme Adaptations & Antarctic Food Webs
- Micro-animals are extremophiles. Tardigrades and others survive freezing, dryness, and darkness by entering suspended animation ("tun state").
- Quote: “It’s that incredible ability…pop back to life six months later, that they can extend their life from two months to decades.” (53:25)
- Food webs: Predator-prey interactions at a microscopic scale (predatory, omnivorous, and herbivorous tardigrades; rotifers; nematodes).
- Antarctic plants: No vascular plants in the Dry Valleys, but “layer cake” microbial mats and mosses.
9. Macroscopic Life, Mummies, and Misfits
- Inland: Penguins/seals can't survive—mummified remains are occasionally found due to the dry, cold conditions.
- Coastal/sea ice: Penguins, seals, orcas, sea spiders, prolific sub-ice marine life.
- Memorable moment: The observation tube ("obtube") experience—crawling down a tiny pipe under 9 feet of sea ice to sit surrounded by Antarctic marine life. (43:10, 73:53)
- Quote: “It’s just you in a metal pipe suspended in the middle of the ocean with no one else around… surreal and it'll stay with me forever.” (73:53)
10. Science, Waste Management & Environmental Stewardship
- Leave No Trace: All waste—including human waste—must be shipped back to the originating country (for the US, to LA).
- Quote: “All of the human waste…gets put on a cargo ship that goes to LA and gets disposed of around the LA area.” (47:05)
- Bathroom logistics: Buckets and coffee cans, outhouses in field camps (Pee bottles for hikes).
11. Climate Change, Microplastics, and Fragility
- Climate impacts are uneven: Antarctic Peninsula warming fastest; dry valleys’ frozen lakes predicted to melt within decades.
- Microplastics: Found even in the guts of Antarctica’s only terrestrial insect. ("You still find plastic in its guts…really brings home how widespread the problem is." (71:37))
- Research differentiates between external contamination vs. environmental sources.
12. International Governance & Research Culture
- Governed by the Antarctic Treaty: No nation owns Antarctica; only science and peaceful activities allowed; mutual monitoring.
- New protected zones are currently a political challenge (krill fishing disputes).
13. Gear, Visibility, and Survival
- Outer layers (parka, boots) are provided; all underlayers must be self-purchased (can be costly and women’s options are limited).
- Quote: “All of these sporting goods stores…are like, women like yoga and men like extreme cold sports…” (57:25)
- Jackets are red for visibility in whiteouts, not neon for better contrast.
14. Medical Emergencies, Death, and Extremes of Experience
- No pregnancies or births allowed for US/most programs—but a few historical stunts exist.
- Emergencies (medical/evacuation): Difficult especially in winter due to darkness, weather, and logistical complexities.
- Death: Remains are flown out—no burial.
- Quote: “You’ve got to send a plane down and get them out…You just never want your rescue crew to risk their lives more than they need to.” (61:37)
15. Tourism, Support Staff, and How to Visit Antarctica
- Tourism is rising rapidly—over 100,000 tourists a year, mostly via expensive cruises ($10k+).
- Support staff: Electricians, IT, plumbers, cooks—a “better” way for many to experience Antarctica.
- Quote: “All of these Antarctic stations…need support staff…You get to actually be involved in supporting science…” (65:09)
- Science collaboration: Takes genuine, multi-year networking and humility.
16. Antarctic Senses – Sound & Smell
- Soundscape: Wind and footsteps, no vegetation; remarkable quiet and “smell-less” air.
- Quote: “It’s mostly wind and…the sound of your own footsteps…It is utterly, utterly quiet.” (68:11)
- Sensory reset: “Fresh” air is redefined on return to plant-rich regions.
Notable Quotes & Moments
On taking risks:
“I was like, what the hell did I put myself up to? Like, who says, yeah, I’ve never filmed a documentary before and I’m going to do it in Antarctica for the first time, all myself, no crew, no problem.” – Ariel Waldman (72:57)
On Antarctic solitude:
“A lot of my days were completely by myself, but you at least get to have still like shared meals with a small group of people.” – Ariel Waldman (15:12)
On beauty amidst the micro-scale:
“I wasn’t ready for just that beauty…some of the creatures I saw—just beautiful, huge diatoms, microalgae that’s encased in glass. It looks as if someone sculpted this intricate jewelry…” – Ariel Waldman (49:24)
On adaptation:
“If you flash freeze a tardigrade, it’s not going to survive. They need to get a heads up that things are not right.” – Ariel Waldman (54:39)
On governance:
“No one owns Antarctica. There are countries that would like to claim a piece of it, but it’s not internationally recognized…” – Ariel Waldman (34:54)
