There are roughly 3 million shipwrecks in Earth’s oceans, lakes, and rivers, according to an astounding estimate by UNESCO. Many wrecks lie where you’d expect them to be, like the World War II wreck-yards of the West Pacific and North Atlantic. And there are wrecks where you’d never think, including the desert of Namibia and under cornfields in Kansas. There are even wrecks in New York City: After the twin towers fell on 9/11, excavators found a shipwreck under the rubble from 1773—they dated the ship by examining the rings in its wood planks.
Like celebrities, there are the A-list shipwrecks. The Titanic, the Lusitania, and the Endurance have their own films, books, fan clubs, museum exhibits, and consumer products. But there’s another class of wrecks: the missing, forgotten, and the quietly but eye-poppingly valuable.
Several in this class have been missing for centuries, some carrying millions (or billions) in lost treasure. The key to finding them, according to famed wreck hunter David Mearns, isn’t to laboriously search the seabed, but to do months or years of research on every detail of a ship, including how it was built, where it went down, and any eyewitness accounts. Anyone can get started from their house, Mearns told me in an interview for my new book, Sinkable: Obsession, the Deep Sea, and the Shipwreck of the Titanic.
