Coral reefs, the rainforests of the sea. Teeming with life, these underwater cities support 25% of marine species despite covering less than 1% of the ocean floor. They shield coastlines from storms and erosion, and sustain millions of people via food, tourism, and fishing. But coral reefs are also vital indicators of ocean health, and their rapid decline is a warning siren for the planet.

Dr. Orion McCarthy is sounding it. But he also may help silence it, through brilliant use of photogrammetry. Re/Capped in issue #44’s highlight of a partnership between Seatrees, the Scripps Institution of Oceanography, and Samsung, smartphone photogrammetry is creating a sea change for reef monitoring, analysis, and communication.Dr. McCarthy speaks to Ellis Malmgren, with astounding footage, about the origins of coral reef danger, what we face if we lose them, the Samsung collaboration, ecosystems, kelp, why 3D excels in stories and showcasing recovery, artificial general intelligence, optimism & pessimism, academia, intense moments under water, and what makes Hawaii special.
