![]() ![]() Toward the southern end of the Mariana Trench lies the Challenger Deep. The site of Jack and Rose’s true (albeit fictional) love, the sunken Titanic, can be found at 12,467 feet.Īccording to National Geographic, if you were to put Mount Everest at the bottom of the Mariana Trench, its peak would still sit around 7,000 feet below sea level. Whales aren’t usually seen below about 8,200 feet. Nuclear submarines hover around 850 feet below the surface as they travel through the ocean waters. Temperatures are just above freezing, and everything is drowning in darkness.įor comparison, most ocean life lives above a depth of 660 feet. Floor vents release bubbles of liquid sulfur and carbon dioxide. At that depth, the weight of all that water above makes the pressure in the Trench around opens in a new window1000 times higher than it would be in, say, Miami or New York. The Trench sits like a crescent-shaped dent in the floor of the Pacific Ocean, extending over 1500 miles long with an average width around 43 miles and a depth of almost 7 miles (or just under 36,201 feet). What’s down there? How deep is the Mariana Trench? Somewhere between Hawaii and the Philippines near the small island of Guam, far below the surface of the water, sits the Mariana Trench, the deepest spot in the ocean. ![]() Bacteria and small invertebrates are able to survive in the deepest spot. The site of the sunken Titanic, can be found at 12,467 feet. For comparison, most ocean life lives above a depth of 660 feet. Oceanogr., 14, 537–551.The Mariana Trench is a crescent-shaped dent in the floor of the Pacific Ocean, extending over 1500 miles long with an average width around 43 miles and a depth of almost 7 miles (or just under 36,201 feet).

Power spectra of daily mean currents showed three spectral peaks at periods of 100 days, 28–32 days and 14–15 days. A westward mean flow prevailed at the stations, and no cyclonic circulation with mean flows of the opposite directions was observed in the Mariana Trench at a longitude of 142☃5′ E. The mean flow at 7009 m depth at the northern station was 0.7 cm s −1 to 240°T, and that at 6615 m depth at the southern station was 0.5 cm s −1 to 267°T. Two current meters were set at 6608 m and 7009 m at a station 24.9 km north of the center for 443 days from 31 July 1995 to 16 October 1996, and two current meters at 6214 m and 6615 m at a station 40.9 km south of the center for 441 days from 2 August 1995 to 16 October 1996. Although rotor revolutions in 60 minutes of recording interval were zero for 37.5% of the time, the maximum current at the deepest layer of 10890 m was 8.1 cm s −1, being composed of tidal currents, inertia motion and long period variations. Three current meters were set at 9687 m, 10489 m and 10890 m at the station in the center of the Challenger Deep for 442 days from 1 August 1995 to 16 October 1996. ![]() The bottom currents in the Challenger Deep, the deepest in the world, were measured with super-deep current meters moored at 11☂2′ N and 142☃5′ E, where the depth is 10915 m.
