How Deep Can You Go?

3 Deepest Ocean Trenches
Mariana Trench, Pacific Ocean, 35760 - 36090 ft., 6.77 - 6.84 miles
The Challenger Deep is the deepest surveyed point in the oceans, with a depth of about 36,000 feet. The exact depth is unknown. The United States Navy bathyscaphe Trieste reached the bottom at 1:06 p.m. on January 23, 1960

Tonga Trench, Pacific Ocean, 35,702 ft., 6.76 miles. is located in the Pacific Ocean and is 10,882 meters (35,702 ft) deep at its deepest point, known as the Horizon Deep. The convergence is taking place at a rate estimated at approximately 15 centimeters (6 in) per year (by Lonsdale, 1986); however, recent Global Positioning Satellite measurements indicate in places a convergence of 24 centimeters (10 in) per year across the northern Tonga Trench, which is the fastest plate velocity recorded on the planet (Bevis et al., 1995).

Philippine Trench, Pacific Ocean, 34,580 ft., 6.55 miles. The Philippine Trench or Philippine Deep or Mindanao Trench or Mindanao Deep is a submarine trench to the east of the Philippine Islands. Its deepest point, the Galathea Depth, has a depth of 10,540 meters (5,763 fathoms or 34,580 feet). Until 1970 the Philippine Trench was regarded as the deepest point of the earth.
