BERING SEA, Alaska — This past summer, the Greenpeace ship M/V Esperanza carried two manned submersibles, a remotely-operated vehicle (ROV) and an international research team to the Bering Sea for a three week survey of Zhemchug and Pribilof Canyons,to map and document deepwater corals living at depths of more than 1,000 feet. The expedition was conceived of and was led by Greenpeace. 1planet1ocean president David E. Guggenheim participated as a sub pilot and scientific consultant. Pribilof and Zhemchug Canyons revealed diverse and complex ecosystems, rich with corals, sponges, fish and other marine life. They also revealed striking human impacts from trawlers, damage that was documented during the expedition. More than a terabyte of video data and numerous biological specimens are now being analyzed and results are being shared with a range of decisionmakers and decisionmaking bodies, including the North Pacific Fisheries Management Council.
