Where is challenger deep located

They discovered an even deeper location with a depth of 10, meters 35, feet determined by echo sounding. The Challenger Deep was named after the Royal Navy vessel that made these measurements. They reached a depth of 10, meters 35, feet. In researchers from Woods Hole Oceanographic Institution completed the deepest dive by an unmanned robotic vehicle in the Challenger Deep.

Their Nereus robotic vehicle reached a depth of 10, meters. The Mariana Trench is located at a convergent plate boundary. Here two converging plates of oceanic lithosphere collide with one another. At this collision point, one of the plates descends into the mantle. At the line of contact between the two plates, the downward flexure forms a trough known as an ocean trench. An example of an ocean trench is shown in the diagram.

Ocean trenches form some of the deepest locations in Earth's oceans.

Underwater volcanic vent: As the Pacific Plate is pushed into the mantle and heated, water in the sediment is volatilized, and gases are liberated as the basalt of the plate melts.

These gases migrate to the surface to form a number of volcanic vents on the ocean floor. This photo shows gases escaping and bubbles moving towards the surface, expanding as they ascend.

Nevertheless, researchers and oceanographers believe that the Challenger Deep is not the deepest point of the world's oceans. On March 23, , the scientists recorded a sounding of 4, fathoms 26, feet or 8, meters in the region.

Over the years, the measurement was fine-tuned and later consolidated, but the HMS Challenger expedition marked the birth of modern oceanography. It also provided the first map of the ocean floor, showing how it gently slopes away from the land and then plummets thousands of feet into vast, flat plains. The Western Pacific, however, is different. It drops off again into the five-mile deep hole - the Mariana Trench, a natural trench that runs twice the length of California and is 30 times deeper than the Empire State Building is high.

On January 23, , Trieste, an Italian research bathyscaphe, became the first manned watercraft to reach the bottom of the Challenger Deep. We were trying to do the project sort of out of sight because we weren't too sure it was going to work," Walsh once told. We looked around, checked everything. If the inner window had cracked, we would've been instantly dead," added Don Walsh. Walsh and Piccard decided to proceed with the dive. They spent five hours descending and reached a depth of 35, feet 10, meters.

They found flatfish at the bottom, took a self-portrait, and initiated a return to the surface. The underwater explorers only spent 20 minutes at the bottom of the world.
