David Gallo is a pioneer in mapping ocean terrain.
"When you go to the bottom of the sea, there are mountains, rivers, valleys, waterfalls, lakes. All the things we are familiar with on land, we find at the bottom of the sea, and they all need to be explored."
Gallo helps locate the remains of missing airliners. On this edition of River to River, he explains why it’s so hard to find wrecks.
The short answer? More than 90% of the ocean floor is unexplored.
“When something sinks to the bottom of the sea, it’s going into a totally unexplored space," Gallo says. "In some ways, it might as well be on Mars; but on Mars you can actually see it.”
