National Geographic Explorer-in-Residence James Cameron explored the deepest point on the surface of the Earth for about three hours on Sunday before resurfacing. Although Cameron’s expedition to the Mariana Trench’s Challenger Deep location was shorter than planned due to a hydraulic fuel leak in his sub called the DEEPSEA CHALLENGER, he was able to get a look at the deepest ocean floor, which he described as bleak. “It looked like the moon,” he said. He didn’t see much in the way of sea life, either. “I didn’t find anything that looked alive to me, other than a few [shrimplike] amphipods in the water,” he said from aboard the research vessel Mermaid Sapphire.
Among the 2.5-story-tall sub’s tools are a sediment sampler, a robotic claw, a “slurp gun” for sucking up small sea creatures for study at the surface, and temperature, salinity, and pressure gauges. Although Cameron had originally planned to collect samples with the sub’s hydraulic arm, the leak made that impossible. Despite the setbacks, Cameron and the DEEPSEA CHALLENGER made history by making the deepest solo dive ever! Cameron, well-known for his films Titanic and Avatar is also an ocean explorer. He dived to the wreckage of the Titanic 33 times.

Did you know that scientists know more about the surface of Mars than about the deepest points of the Earth?
James Cameron, filmmaker and National Geographic Explorer and his DEEPSEA CHALLENGE team are embarking on a voyage to advance the world’s understanding of our ocean’s
vast range of biological and geological phenomena. The historic
expedition to the Mariana Trench’s lowest point, Challenger Deep, which
lies 6.83 miles (10.99 kilometers) below the ocean surface.That is deeper than Mt. Everest is tall. This journey is the first
extensive scientific exploration in a manned submersible of the deepest
spot on Earth. James Cameron will pilot the DEEPSEA CHALLENGER vessel, which is
outfitted for scientific exploration and analysis. He will
conduct tests, collect samples, and document the experience in the
high-resolution 3-D for which he’s known globally.
