- The organisms known to exist in the Arctic basin, where the Gakkel is located, may have evolved in a unique fashion because they were mostly isolated from the life in the deep waters of other oceans for all but the last 25 million years, said Robert Reves-Sohn, the expedition's lead scientist.
The job of reaching any new organisms at the ridge falls to scientists operating three new robotic vehicles, two of which are designed to navigate untethered under the ice.
The two robots, named Puma (other-otc: PMMAY.PK - news - people ) and Jaguar, cost about $450,000 each and received significant funding from NASA because their mission is similar to what scientists hope to do in a future exploration under the ice of one of Jupiter's moons, Europa.
The robots are built to descend to about 5,000 meters and work 5 to 6 meters off the bottom, photographing and removing samples, said Hanumant Singh, the project's chief engineer.
