James Cameron, maker of films Titanic and Avatar, became the first person to make a solo dive to the Pacific Ocean valley known as the Challenger Deep, southwest of Guam. He has safely returned to the ocean surface after a solo submarine dive.
Deep Sea Challenge Mission partner the National Geographic said Cameron had reached the depth of 35,756 feet (10,898 meters) at 7:52 am Monday local time (2152 GMT Sunday) in the Mariana Trench in his specially designed submersible.
Cameron spent several hours on the Pacific Ocean sea floor, collecting samples for scientific research and taking still photographs and moving images. His goal was to bring back data and specimens from the unexplored territory. He is expected to announce the results of the experiment later.
