Archeology in the Deep

When I first met Brendan Foley last fall, I was immediately struck by the scope of his ideas. He's the resident archeologist at the Woods Hole Oceanographic Institution (there's only one), and he studies ancient shipwrecks in the Mediterranean. But Foley's style of archeology is very different from traditional forms. Instead of spending years excavating a single site, he wants to take a big picture approach, using tiny robotic vehicles to quickly find and catalog as many ancient wrecks as possible--gathering useful data about the size, shape, and contents of each vessel without ever touching them.

In the ancient world, Foley says, sailing ships were the vector for the exchange of goods, food, and even ideas between ancient cultures. "Sailing was safe, but not perfectly safe," he says. "A small percentage of all sailing voyages end in wrecking events. What we're left with, then, on the bottom of the Mediterranean, is a random sampling of everything that ever moved across the Mediterranean throughout antiquity. Really, the entirety of the human experience lies there on the sea floor."

Foley thinks that by collecting basic information on a vast number of wreck sites, he can start filling in gaps in our understanding of the very early days of western civilization. His ultimate goal is an ambitious one--to document and compare every known wreck in the Mediterranean. Right now, he's doing it one site at a time. But as the technology of autonomous underwater vehicles improves, he thinks it might be possible one day to conduct the survey remotely using a fleet of small robot submarines.

Of course, that's years away from being a possibility. But who knows? if technology catches up to his vision, Foley's work could provide new insights on the origins of western civilization.

You can hear Foley describing his work in his own words in this podcast I released a couple days ago:

Hi I am attempting to have someone look into the story I believe was featured on NOVA in the last 4 years. Could not find in your archives. It was a European male explorer/underwater archeologist who discovered a ship underwater but locked off the water in the middle of the ocean and pumped the water out. I thnk this method could be used to help stop the oil leak. Thank you.
