London: James Cameron described his record-breaking dive seven miles into the depths of the ocean as "going to another planet".
The director spoke to reporters after becoming the first person to make a solo dive to the Mariana Trench. He spent around three hours on the bottom collecting research samples for marine biology, geology and geophysics and taking still photographs and video footage of the trench.
"My feeling was one of complete isolation from all of humanity. I felt as though literally in the space of one day, I`ve gone to another planet and come back," the Telegraph quoted him as saying.
The dive follows seven years of planning and the design and construction of a specialised submarine that allowed Cameron to withstand the immense pressure at the ocean floor.
"The whole sub actually squeezes down almost three inches in length just because of the pressure. The sphere that I`m in actually shrinks. The window that I look out actually pushes in towards me under 16,000 pounds per square inch of pressure," he added.
Cameron said that there were no large creatures there - only small shrimp-like animals that were an inch in length.
"Any of the animals that live there are adapted to this extreme pressure, this total darkness. They`re usually white, they have no pigment. Some of them have eyes to see bioluminescence, some of them have no eyes at all. It`s a completely alien world," he said.
