BBC : The extreme water pressure of the Kermadec Trench in the southwest Pacific Ocean near New Zealand is thought to have caused the destruction of the Nereus, a robotic underwater vehicle built by the Woods Hole Oceanographic Institution. On 10 May, while diving to a depth of almost 10 km, the Nereus ceased communicating with the research team that was using it to explore one of the deepest ocean trenches in the world. A search near the dive site revealed several pieces of debris floating on the surface; they were later identified to be from the Nereus. The evidence suggests the vessel suffered a catastrophic implosion. Workers continue to look for debris in order to learn more about why the vehicle failed.
