I discovered hydrothermal vents, but I’m only known for finding the Titanic

The discovery of these underwater hot springs in 1977 solved the mystery of how life first began on Earth, but it was locating the world's most famous shipwreck that made me a celebrity

The mid-ocean ridge is where the Earth creates its outer skin. It's called the boundary of creation. We knew there was life on the bottom of the ocean but not entire ecosystems supporting large animals until our expedition went down there in 1977.

First, we sent down an unmanned vehicle called Angus, which was essentially a camera system and strobe lights within a two-tonne steel cage. It was going down in the eternal darkness, slaloming back and forth like a skier down a mountain.
