James Cameron’s Deepsea Challenge expedition
March 22, 2012
Relying on advanced engineering and technologies created by Cameron and his team, successful field tests were completed off the coast of Papua New Guinea. They included untethered deep-water dives — including one to a depth of more than 5 miles (more than 8 km) — in the revolutionary, single-pilot Deepsea Challenger submersible, the result of an eight-year engineering effort and the deepest-diving manned marine vehicle in existence.
“The deep trenches are the last unexplored frontier on our planet, with scientific riches enough to fill a hundred years of exploration,” Cameron said. “National Geographic, which has been exploring the world for nearly 125 years, is the ideal partner to help usher in a new era of deep-ocean research and exploration that supports leading scientific institutions in answering questions about the deepest, unexplored parts of the Earth. Our goal is to build a scientific legacy for generations to come. It’s also to inspire people across the globe to celebrate exploration and to explore with us online and through the media we produce.”
They spent approximately 20 minutes on the ocean floor before returning to the surface. Now, 52 years later, Cameron’s Deepsea Challenger represents breakthroughs in materials science, unique approaches to structural engineering and new ways of imaging through an ultra-small, full ocean depth-rated stereoscopic camera. Cameron’s Cameron-Pace Group, which supplies 3-D technologies and production support services, has provided the capability to document the historic expedition in high-resolution 3-D.
Cameron was named a National Geographic Explorer-in-Residence in 2011. While working on his film “Titanic,” he took 12 submersible dives to the famed shipwreck two and a half miles down in the North Atlantic. The technical success of that expedition led Cameron to form Earthship Productions, which develops films about ocean exploration and conservation. Since then he has led six expeditions, authored a forensic study of the Bismarck wreck site and done extensive 3-D imaging of deep hydrothermal vent sites along the Mid-Atlantic Ridge, the East Pacific Rise and the Sea of Cortez. Cameron has made 72 deep submersible dives, including 33 to Titanic. Fifty-one of these dives were in Russian Mir submersibles to depths of up to 3.03 miles (4.87 km).
The Deepsea Challenge expedition will be chronicled for a 3-D feature film for theatrical release on the intensive technological and scientific efforts behind this historic dive, which will subsequently be broadcast on the National Geographic Channel, and documented for National Geographic magazine.
Scripps Institution of Oceanography, UC San Diego, is the Deepsea Challenge Project’s primary science collaborator. For nearly a decade, Scripps has been involved with James Cameron in developing new ways to explore and study the deepest parts of the oceans. With its decades-long history of deep-sea exploration, Scripps is recognized as a world leader in investigating the science of the deep ocean, from exploring the deep’s geological features to researching its exotic marine life inhabitants.
Parts of the Mariana Trench are now protected under a 2009 proclamation by President George W. Bush that established the Marianas Trench Marine National Monument and gave management responsibility to the U.S. Fish and Wildlife Service in consultation with the National Marine Fisheries Service. The U.S. Fish and Wildlife Service issued permits for the dive in the U.S. areas of the Monument. Permits for other parts of the Challenger Deep and beyond were secured from authorities in the Federated States of Micronesia.
