New Submersible to Dive in French Polynesia
Ocean-conservation veteran Dr. Sylvia Earle’s company DOER Marine is preparing its first operational test of the “Honu” submersible. The three-passenger vehicle will travel to depths of 1,000 metres for up to eight hours, with the inaugural dive slated for later this year in French Polynesia. Earle argues that, when built to certified safety standards, submersible travel can be “safer than flying.”
From Titan Tragedy to a Fresh Start
Public wariness of underwater craft surged after the 2023 Titan implosion, which killed five explorers 3,500 metres below the Atlantic and prompted a U.S. Coast Guard inquiry that forced OceanGate to cease operations. Earle, the first woman chief scientist at the U.S. National Oceanic and Atmospheric Administration (1990) and a former participant in the 1970 Tektite II experiment, sees Honu as a way to restore confidence and expand scientific access to the ocean’s abyss.
Ocean Knowledge Gaps and Conservation Stakes
Scientists have directly observed only 0.0001 percent of the deep ocean, despite it covering more than 70 percent of Earth’s surface. Human activity has already degraded roughly half of global coral-reef ecosystems, and merely 3 percent of ocean areas enjoy formal protection. Earle warns that continued exploitation—such as proposed deep-sea mining near American Samoa and a $5 billion Gulf of Mexico oil project—could push marine systems toward irreversible tipping points.
Earle’s Vision and Calls to Action
In the interview, Earle stresses that the ocean supplies most of the planet’s oxygen and acts as a major carbon sink, making its health essential for humanity.
Verbatim Quotes
- “I first met the ocean when I was 3,” — Dr. Sylvia Earle
- “It's just kind of disheartening to realize how one species — that would be us — how dreadfully effective we have been at eliminating the very fabric of life that is essential for our existence,” — Dr. Sylvia Earle
- “But the good news is the kids are growing up knowing we've got problems. But they also know there are solutions and that on their watch, our watch right now, this is the best chance we have ever had as a species to shape the world we want, not just the world we get,” — Dr. Sylvia Earle
