Scientist Michelle Ridgway talks about the samples collected with the submarine in the underwater canyons. Greenpeace spends two months with the ship Esperanza in the Bering Sea, to investigate deep sea habitats and to conduct scientific surveys of underwater canyons. By utilizing state-of-the-art technology to observe coral, sponges and hopefully discover new species, Greenpeace will push for greater protection of the Bering waters.
