Los Angeles - Titanic director James Cameron has donated the world's deepest diving submarine to the Woods Hole Oceanographic Institute, it was announced on Tuesday.

News of the donation came exactly a year after Cameron piloted the DeepSea Challenger to a depth of almost 11 000 metres in the Mariana Trench, the deepest place on earth.

In a statement, Woods Hole said it would work with Cameron to incorporate the sub's numerous engineering advancements into future research platforms and deep-sea expeditions. Cameron will also serve on the institute's Centre for Marine Robotics advisory board.

Cameron has long been fascinated with the ocean depths, starting from his 1989 film The Abyss, and including his 1997 Titanic blockbuster; Expedition: Bismarck, in 2002; Ghosts of the Abyss in 2003; and Aliens of the Deep in 2005. - Sapa-dpa
