Life in some of the deepest ocean trenches in the world is being revealed by a UK-built video system designed to withstand pressures that would cause any other device to implode. The autonomous camera, developed at Aberdeen University's Oceanlab, recently filmed fish at 7,700m beneath the surface of the Pacific Ocean - the deepest any fish have been captured on video - and it has the potential to explore even greater depths. In laboratory tests the camera withstood pressure of l,400bar, which would be found at sea depths of 14,000m. The Mariana Trench in the eastern Philippine Sea, the deepest part of the world's oceans, has a maximum depth of 11,000m.
