Vityaz-D is the first underwater vehicle to operate autonomously at the extreme depths of the Mariana Trench. The duration of the mission, excluding diving and surfacing, was more than 3 hours. [36] [37] On 10 November 2020, the Chinese submersible Fendouzhe reached the bottom of the Mariana Trench at a depth of 10,909 m (35,791 ft; 5,965 fathoms).
The Marianas Trench Marine National Monument is a United States National Monument created by President George W. Bush by the presidential proclamation no. 8335 [3] on January 6, 2009. [4][5][6][7] The monument includes no dry land area, but protects 95,216 square miles (246,610 km 2) of submerged lands and waters in various places in the ...
Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe. In 1960, it became the first crewed vessel to reach the bottom of Challenger Deep in the Mariana Trench, the deepest point in Earth's seabed. [2] The mission was the final goal for Project Nekton, a series of dives conducted by the United States Navy in the Pacific ...
The Challenger Deep is the deepest surveyed spot in the world's oceans, and is located in the Mariana Trench, southwest of Guam. [7] From February 16, 1960, to May 10, 1960, the submarine USS Triton, under the command of Captain Edward L. Beach, Jr., made the first submerged circumnavigation of the world.
Oceanic trenches are prominent, long, narrow topographic depressions of the ocean floor. They are typically 50 to 100 kilometers (30 to 60 mi) wide and 3 to 4 km (1.9 to 2.5 mi) below the level of the surrounding oceanic floor, but can be thousands of kilometers in length. There are about 50,000 km (31,000 mi) of oceanic trenches worldwide ...
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April – 4 May 2019). The Challenger Deep is a relatively small slot-shaped depression in the bottom of a considerably larger crescent-shaped oceanic trench, which itself is an unusually deep feature in the ocean floor.
On 23 January 1960, Piccard and Lt. Don Walsh reached the floor of the Mariana Trench located in the western North Pacific Ocean. The depth of the descent was measured at 10,916 meters (35,813 feet); later, more accurate, measurements during 1995 found the Mariana Trench to be slightly less deep at 10,911 m (35,797 ft). The descent took four hours.
In 2021 he and Lahey traveled to the Mariana Trench, the deepest point on Earth, before Connor went on to become the first person to travel the depths of the ocean and space in one year.
