Eric Stackpole describes how building a DIY whale tag during a National Geographic expedition let him record unprecedented footage from the back of a sperm whale. The video’s core point is that exploration is no longer constrained mainly by tools; instead, curiosity is now the limiting factor, and new technology can reveal both scientific data and emotional context.

Eric Stackpole frames the talk around a COVID-era research expedition aboard the Ocean Explorer, a ship he says was built for both research and storytelling. He explains that his background as an engineer who liked tinkering more than school led him to build low-cost underwater robots meant to democratize exploration, which in turn helped land him the job filming the show. The setup is personal and reflective rather than financial or market-focused. The central story is the team’s attempt in the Azores to tag a sperm whale with a very DIY device assembled by whale biologist Rui Peredo. Stackpole emphasizes how improvised the tag was — a taken-apart action camera, a light, a radio beacon, and suction cups — and how fragile the process felt. …
No immediate market setup is present. The nearest actionable signal is thematic interest in low-cost robotics and ocean-data tools, but the transcript is not an investment pitch.
Over a longer horizon, the implied path is continued adoption of bespoke sensing and underwater robotics for research, especially where standard tools miss behavior in the wild. The view would be strengthened by repeatable discoveries from similar tags rather than one-off spectacle.
The structural message is that discovery is becoming more democratized: smaller, cheaper, purpose-built tools can expand what humans can observe. If that holds, the durable regime is one where curiosity and engineering creativity matter more than scale alone.
The Ocean Explorer was used as both a research vessel and a storytelling platform.
Stackpole says the ship was designed for research and storytelling.
Low-cost underwater robots helped democratize exploration and played a role in getting the show producers interested.
He ties his robot-building work to the opportunity to film the show.
The DIY whale tag barely worked and required late-night improvisation to function.
He describes soldering and improvising until the device finally worked at 2 a.m.
