Underwater footage of the damage caused by trawlers' net in Pribiloff and Zhemchug underwater canyons at the depth of 900 - 1600 ft. 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.
