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.

Expedition to the Bering Sea Concludes Successfully with New Insights, New Questions

With a Terabyte (1,000 Gigabytes) of high-definition video, photographs and other data, along with numerous biological samples, now making their way around the world to scientists, policymakers and public forums, new insights and perspectives are emerging as the hard work of reviewing this vast volume of new data moves forward. The science team and sub pilots have departed Esperanza, which is continuing west along the Aleutian Island chain, continuing important outreach to local communities. The ship will eventually continue west to Japan.

Before departing Dutch Harbor, the science team/sub pilots made the first public presentation of its findings, including imagery and videos, to the community of Unalaska. The following day, members of the community were invited aboard Esperanza during an Open House to meet with the crew and see the ship up close. Read more

Esperanza Heads South to Dutch Harbor with New Insights

Location of Pinnacles Remains a Mystery

The Esperanza began its 2-day steam south and endured gale-force winds and 15-foot seas along the way, but all are well and grateful for the successes along the way. The team achieved a total of 25 sub dives during the expedition, well-exceeding expectations for this part of the world where weather is typically unforgiving.

The team collected nearly a Terabyte (1,000 Gigabytes) of high-definition video, photographs and other data, now being archived, cataloged and distributed. Also collected were numerous coral, sponge, and other invertebrate samples which are being prepared for distribution to scientists around the world for further analysis. Read more

Deep Dives at Zhemchug Canyon Reveal Corals, Intricately Woven Ecosystem

Before rough seas rolled in on Tuesday, the team aboard Esperanza was able to complete six manned submersible dives and three ROV dives at Zhemchug Canyon, considered the largest canyon in the ocean. The subs worked close to their maximum depth of 2,000 feet while the ROV worked at its deepest depth ever, around 3,000 feet. Numerous coral species were present and documented throughout the dives.

Zhemchug Canyon has also revealed an intricate ecosystem whose inhabitants depend upon small holes or rises in the otherwise flat, silty bottom, including “flatfish holes,” depressions made by halibut, flounder, sole and skates, and drop-stones, rocks and boulders that fall from melting icebergs above.

Esperanza Now at Zhemchug Canyon, Largest Underwater Canyon in the World

Continued favorable weather and few mechanical problems means that the team aboard Esperanza has been able to complete 14 manned submersible dives at Pribilof Canyon. On Saturday (August 4), Esperanza arrived at Zhemchug Canyon to explore this, the largest undersea canyon in the world, much larger than the Grand Canyon. Within the first few minutes of the deepest ROV dive yet, more than 3,000 feet down, the team discovered corals, including pink “bubblegum” corals along with other soft corals.

Earlier, during the final dives at Pribilof Canyon, the team documented numerous corals, but also evidence of extensive trawling damage in the area. Read David Guggenheim’s account in his OceanDoctor blog. Read more

Exploration of Pribilof Canyon Now Under Way, Revealing Rich Ecosystem, Corals

Thanks to great weather, state-of-the-art equipment and a top-notch crew, it has been a productive weekend for the team aboard Esperanza which arrived on site at Pribilof Canyon Saturday morning (July 28) when David Guggenheim and Michelle Ridgway made the first tandem dive in two DeepWorker submarines into Pribilof canyon to a depth of just over 1,000 feet and began to document a fascinating diversity of life, including a variety of corals, anenomes, sponges and fish. On Sunday, the ship visited a second site in Pribilof Canyon where John Hocevar and Timo Marshall completed a successful tandem dive, documenting more corals and successfully collecting a number of specimens with DeepWorker’s manipulator arm for analysis by scientists around the world.

Already, the Greenpeace-led team has accumulated nearly 16 hours of bottom time (8 hours per sub), more than all of the previous research done in this region combined. The subs’ high-definition video cameras have already collected over 120 Gb of data. The subs are performing linear transects which will then be analyzed on the video. Twin lasers spaced 20 cm apart allow accurate analysis of the size of organisms encountered. Read more

Esperanza Sets Sail from Dutch Harbor: Bering Sea Expedition Under Way

The Expedition to the Bering Sea officially got under way as the M/V Esperanza departed Dutch Harbor, Alaska on Friday, July 27 at 4pm Alaska Daylight Time. The Esperanza will steam through the night — for roughly 15 hours — to its first destination, Pribolof Canyon near the Pribolof Islands in the Bering Sea. The first DeepWorker dives are scheduled for Saturday morning.

In June, an international team of researchers and conservation specialists recently completed a week of intensive training and preparations for this Greenpeace-led expedition to Alaska’s Bering sea. The Esperanza is carrying two manned submersibles, a remotely-operated vehicle (ROV) and the research team to the Bering Sea for a three week survey of Zhemchug and Pribilof Canyons, specifically to map and document deepwater corals living at depths of more than 1,000 feet.

About

1planet1ocean is a nonprofit organization, founded to explore, restore and sustain the oceans through strong international partnerships, offering solutions to the problems our oceans face.

The ocean once stood as a forbidding, impenetrable divide that held civilizations apart for centuries. With the advent of paddle, sail, then steam, the seas began to unite the world through exploration and trade. Today, we understand that the ocean doesn’t divide us – it unites us. Ocean currents forge critical ecological linkages across vast ocean stretches. International collaboration is essential to protect the waters that we share. The 21st century has opened with an unprecedented opportunity to make this the century of the ocean. In the United States, two separate commissions – the U.S. Commission on Ocean Policy and the Pew Oceans Commission – offer a dire look at the state of U.S. marine ecosystems, but also a blueprint for their restoration and sustainability, and a once in a generation opportunity to create new laws and practices to ensure enduring protection. The momentum generated by these commission reports offers new opportunities for conservation, both domestically and internationally. There is a need to better engage the public, decision-makers and research institutions in this effort.

The name 1planet1ocean signifies the fact that the oceans no longer divide us, but indeed unite us, and a united effort — involving strong international collaboration — is needed to develop solutions that restore and sustain the world’s oceans. The name 1planet1ocean was inspired by the phrase “Un planeta, un oceano” [One planet, one ocean] written on the back of the official conference T-shirt of the 2003 MarCuba conference in Havana, Cuba.

Areas of Focus:

• Expeditionary research to identify and map important marine ecosystems, especially coral ecosystems, in order to inform strong conservation policies. Regions of interest include the Gulf of Mexico (with emphasis on Cuba’s northwest coast) and the Bering Sea.
• Sustainable aquaculture and the promotion of next-generation land-based recirculating aquaculture systems in order to reduce pressure on wild fish stocks and provide a sustainable alternative that supports local communities.
• Connecting people to the oceans through outreach, education, videography, photography and leading-edge Web technologies.
