Located in the Pacific Ocean near the Mariana Trench, the Challenger Deep is the deepest known point of the ocean floor. Only four manned descents have ever braved the journey to this remote location. On March 26, 2012 filmmaker James Cameron piloted the deep submergence vehicle Deepsea Challenger to become the first person to complete a solo dive of this ocean frontier. Listen in as he shares his experiences and perspectives from his record-setting dive.
In spring 2012, the Deep Sea Challenge Expedition, with film director and National Geographic Explorer in Residence James Cameron, conducted submersible operations in the deepest point on Earth, the Mariana Trench.
In “Exploring Beyond the Abyss: The Deep Sea Challenge Expedition,” Scripps Institution of Oceanography’s Doug Bartlett, the chief scientist of this headline expedition and a leading expert in microbial life in the planet’s most remote and extreme places, describes what the journey was like and how his research is providing greater insight into how organisms thrive in such extreme depths of the ocean.
