Which film director dived to the bottom of the Mariana Trench in March 2012?
Hadal zone have occurred. "HROV Nereus" was thought to have imploded at a depth of 9,990 meters while exploring the Kermadec Trench in 2014. The first manned exploration to reach Challenger Deep, the deepest known part of the ocean located in the Mariana Trench, was accomplished in 1960 by Jacques Piccard and Don Walsh. They reached a maximum depth of 10,911 meters in the bathyscaphe "Trieste". James Cameron also reached the bottom of Mariana Trench in March 2012 using the "Deepsea Challenger". The descent of the "Deepsea Challenger" was unable to break the deepest dive record set by Piccard and Walsh by
Mariana Trench a survey which mapped the entire trench to resolution. The mapping revealed the existence of four rocky outcrops thought to be former seamounts. The Mariana Trench is a site chosen by researchers at Washington University and the Woods Hole Oceanographic Institution in 2012 for a seismic survey to investigate the subsurface water cycle. Using both ocean-bottom seismometers and hydrophones the scientists are able to map structures as deep as beneath the surface. Four descents have been achieved. The first was the manned descent by Swiss-designed, Italian-built, United States Navy-owned bathyscaphe "Trieste" which reached the bottom at 1:06 pm on 23
