"The Hadal Trenches are one of the last great frontiers in marine science and the deepest places on Earth.
Mostly located around the Pacific rim in areas where tectonic plate collide and plunge, the seafloor reaches depths close to 11,000 metres (~7 miles) in some areas.
The Atacama Trench, a trench almost 6000 km long and more than 8000 m deep, runs along the west coast of South America.
Newcastle University scientists and engineers have been pioneering technology for the exploration of these ultra-deep environments for the last five years and have to date completed nearly 250 deployments of their novel 'lander' systems.
Using two full-ocean depth (11,000 m) capable landers equipped with HD cameras and traps the Newcastle team assessed the animals found within the trench."
