Episode: "A whale’s-eye-view of the ocean"
Guest: Eric Stackpole
Host: Elise Hu
Date: April 11, 2026

Overview:

This episode features engineer and explorer Eric Stackpole as he recounts a groundbreaking project: using a DIY underwater camera rig to capture never-before-seen footage of sperm whales communicating and interacting deep beneath the ocean’s surface. Stackpole argues that in our technologically rich age, the bounds of discovery are set less by our tools and more by our curiosity—emphasizing the value of wonder, democratized exploration, and emotional connection with scientific discovery.

Key Discussion Points & Insights

1. The Story Behind the Whale Footage

• Stackpole describes working on the Ocean Explorer research vessel during the COVID-19 pandemic ([04:10]):

  • Quote: “I had the strange fortune of being sequestered here aboard the Ocean Explorer, one of the most advanced research vessels on the planet…” – Eric Stackpole ([04:11])

• The mission’s highlight came from deploying a homemade whale tag—assembled from an action camera, light, radio beacon, and suction cups ([05:12]):

  • The tag’s construction was challenging and low-tech, “It barely worked. We had to spend nights soldering and improvising to try to get it going.” ([05:38])

• After much suspense, the tag successfully captured the whales’ journey into the depths, yielding unprecedented footage, audio, and communication between sperm whales ([06:17]–[07:00]):

  • Memorable Moment: Stackpole and whale biologist Rui Pareto watched footage from the whale’s perspective, hearing both echolocation and “coda” clicks—social communication between whales ([07:00]):
    • Quote: “That is echolocation... We started hearing a different sound. It was a rapid series of clicks. That's called codas. This is the way sperm whales used to communicate with each other. So we were hearing her talking to another whale. We could not believe our ears. And then we couldn't believe our eyes.” – Eric Stackpole ([06:58]–[07:15])

2. Emotional Impact & The Value of Wonder

• The footage moved Stackpole and Rui to tears; it was more than scientific data—it was “an experience of life” ([07:54]):
  • Quote: “The footage we had seen was not just data. This was an experience of life. It was reminding me why exploration really matters.” – Eric Stackpole ([07:54])
• Stackpole reflects that storytelling in science invites viewers to connect emotionally, not just intellectually:
  • Quote: “Getting to see what it's like to be a sperm whale diving into the deep sea is something our technology has enabled us to do... that moment... helps me understand in a broader sense what being alive on the planet means.” ([16:43])

3. Exploration, Curiosity, and the Human Drive

• Stackpole’s path began with tinkering, not formal academia; he credits curiosity and hands-on experiments for his learning ([12:02]):
  • Quote: “The best way for me to learn is to try things out myself... Tinkering started as a way of indulging my curiosity where the classroom setting wasn't really doing that.” ([12:02])
• For those struggling in traditional learning, Stackpole suggests looking for themes or common threads in what excites you—a practice he likened to “a hound dog with its nose to the ground” ([13:10]).

4. Failure, Iteration, and Success

• Stackpole normalizes failure as fundamental to progress ([14:44]):
  • Quote: “Failure may be one of the most important parts of the process... that's how you learn how to do it better. That really brings things forward.” ([14:44])

5. Democratizing Exploration Through DIY Tools

• Even at the cutting edge, off-the-shelf or DIY equipment is essential:
  • Quote: “You know, there's no whale Tags R Us, especially if you have a very specific question that you're trying to answer.” ([19:45])
  • The openness and accessibility of tools like the OpenROV make discovery possible for more people and promote innovative approaches ([19:45]–[21:24]).

6. Technology: Double-edged Sword

• While advances in tech (notably AI) can open new worlds, Stackpole acknowledges both excitement and potential dangers ([23:33]):
  • Quote: “From the moment we harnessed fire, we were dealing with these sort of double edged sword scenarios... We should treat it with a sort of respect, with a cautiousness, but also with an excitedness and eagerness to see what is possible.” ([23:33])

7. Curiosity as the New Limit ([24:48])

• Modern technology gives us more access than ever—the biggest barrier is now our interest and focus:
  • Quote: “It's more that our understanding is limited by curiosity... We are living in an era now where our tools can give us amazing ability to understand the world in ways never before possible.” ([24:48])

8. Next Frontiers & Internal Exploration ([26:21])

• Stackpole’s latest project: a portable houseboat for immersive, everyday exploration ([26:21])
• He reflects that wonder can come not only from scientific firsts but from personal, everyday experiences in nature.

9. Advice for Listeners ([27:55])

• Learn: There’s always deeper to go—don’t confuse surface knowledge for full understanding.
• Feel: Connect with childlike wonder; awe and emotion are vital to science.
• Do: Don’t wait for permission. Try things yourself, embrace first failures, and persist.

  • Quote: “Just don't wait. Don't wait for permission. That's what I would suggest. Try something out horribly, and if you continue to be interested in it, you'll eventually make it successful.” ([28:03])

    • Catchphrase: “Failure your way to success.” ([30:03])

Notable Quotes & Timestamps

• “We had footage from the back of a sperm whale... For minutes we watched in disbelief as we watched this exchange of these two whales. Friends, family, lovers, we can never know for sure. But what we were witnessing was something no one had ever seen before.” – Eric Stackpole ([06:17]–[07:35])
• “Our tools no longer limit what we can understand. It's more that our understanding is limited by curiosity. So the question isn't what can we explore? ... The real question is, what will we wonder about next?” – Eric Stackpole ([08:35])
• “Failure may be one of the most important parts of the process.” – Eric Stackpole ([14:44])
• “You don't have to personify an animal to relate to it. When you see it diving into the abyss... that's an emotional roller coaster that is sort of relatable.” – Eric Stackpole ([18:13])
• “If you want to do something new, you probably have to do it in a new way.” ([19:45])
• “We are all explorers. We're all trying to find those things to relate to, even in the natural world.” ([18:24])
• “Curiosity is now our biggest limit to exploration.” ([24:48])
• “Just don't wait. Try something out horribly. If you continue to be interested in it, you’ll eventually make it successful.” ([28:03])
