The ExpeditionCasts podcast is back! The series returns with the video version of the Ocean Doctor’s popular blog post, "Attacked by the Giant Squid’s Cousins." (You can access the video version below.) That’s big news. But the GINORMOUS news is that ExpeditionCasts returns along with a new version of Google Earth. Version 5.0 of Google Earth allows you to explore the other 70 percent of the planet — the world’s oceans — and access

stunning underwater video content from around the world. 1planet1ocean has been privileged to be a contributor to this enormous, er, GINORMOUS project, and you’ll find five ExpeditionCasts videos among the others Google Earth 5.0. Look for them in Alaska’s Bering Sea and off the northwestern coast of Cuba.

The project has been a two-year effort stemming from a chance meeting of oceanographer Dr. Sylvia Earle and Google’s John Hanke at a meeting of the Geographical Society of Spain. Dr. Earle pointed out, directly but politely, that Google had done a great job with Google Earth, until you entered the water, that is. Since then, a large team of collaborators was assembled and has worked to bring the other 70 percent of the planet to life in Google Earth 5.0.

Earlier today at the California Academy of Sciences in San Francisco, former Vice President Al Gore, Google CEO Eric Schmidt, John Hanke (Director, Google Earth and Maps), Dr. Sylvia Earle (Explorer-in-Residence, National Geographic Society and Founder, Deep Search Foundation) and others announced Google Earth 5.0 to the world.

We invite you to explore Google Earth 5.0. If you like ExpeditionCasts, we’ll be releasing each of the videos that are part of Google Earth 5.0 over the next few weeks, which you’ll receive automatically if you subscribe to our feed (free) below. We recommend that you subscribe for the best video quality and so you don’t miss a single episode!

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.

The Esperanza is carrying 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 is being led by Greenpeace.

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.

These corals, some nearly two thousand years old, are vital components of the Bering Sea’s rich and unique ecosystem. Unfortunately, these corals are at great risk, ending up in fish trawling nets as “bycatch” or “incidental take,” the unintentional harvest of one species while fishing for another. Many tons of corals have been destroyed by indiscriminant trawling gear which scrapes the bottom and sides of seamounts — underwater mountains — for fish.

It is hoped that the data collected during this expedition will help advance our scientific understanding of these deepwater coral communities and be helpful to policy makers as well, leading to more effective conservation measures. A Scientific Advisory Panel is advising the project, including representatives from Scripps, the Smithsonian, the St. George Island Ecosystem Office, MCBI, Oceana, Texas A&M, and Nova Southeastern. 1planet1ocean president David E. Guggenheim will be serving as a sub pilot and scientific advisor.

The expedition will be using two DeepWorker submarines, one-person mini-subs, untethered, that are capable of a depth of up to 2,000 feet. Each sub is equipped with a high-definition video camera, a manipulator arm for collecting samples, sonar for navigation and is always in contact with the surface using through-water (acoustic) communications.

DeepWorker’s cabin recirculates the air, using carbon dioxide scrubbers similar to what’s used in spacecraft, providing up to 80 hours of life support. A typical dive lasts 4-6 hours.
