Nobody can write that badly. It has to be some sort of computer translation.
Project is pretty interesting.
Wonder if the wun’s BC will be found?
The expedition will traverse 40,000 nautical miles / 74,000 km in 11 months.
By the end of the expedition the sub will have descended through at least 72,000 m / 236,220 ft of water.
Up to 50 scientific lander deployments will be undertaken alongside the submersible dives.
No human has ever been to the bottom of the Java, Puerto Rico* or South Sandwich trenches.
No one has ever been to the bottom of Molloy Deep.
No manned submersible has ever been to Challenger Deep more than once.
No person has ever been to the summit of Mount Everest and also been to the bottom of the ocean at Challenger Deep, which could occur on this expedition.
11,000 meters is 36,089 feet (rounded down). There are 5,280 feet to a mile which is 6.8 miles (also rounded down).
An awesome experience for the adrenaline junkies. At least the first time down. What will he seek next to satisfy his need for adrenaline rushes? 8>)
That it is. I’ve always been interested in very deep dives, ever since I was a kid, reading about Beebe and Barton and their bathysphere. The Oregon Museum of Science and Industry (OMSI) had a bathysphere out in front of their old West Hills location, and we could climb around in and on it.
8>) Took me awhile to realize what you were actually referring to.
I remember that scene from Raise The Titanic where the submersible got destroyed.
Still creeps me a little even if it was a movie that wasn’t anywhere near as good as the book.
It is a crescent-shaped trough in the Earth’s crust averaging about 2,550 km (1,580 mi) long and 69 km (43 mi) wide.
The maximum known depth is 10,994 metres (36,070 ft) (± 40 metres [130 ft]) at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep.[2]
However, some unrepeated measurements place the deepest portion at 11,034 metres (36,201 ft).[3]
For comparison: if Mount Everest were dropped into the trench at this point, its peak would still be over 2 kilometres (1.2 mi) under water.[a]
At the bottom of the trench the water column above exerts a pressure of 1,086 bars (15,750 psi), more than 1,000 times the standard atmospheric pressure at sea level.
At this pressure, the density of water is increased by 4.96%, so that 95.27 litres of water under the pressure of the Challenger Deep would contain the same mass as 100 litres at the surface.
The temperature at the bottom is 1 to 4 °C (34 to 39 °F).[5]
The trench is not the part of the seafloor closest to the centre of the Earth. This is because the Earth is not a perfect sphere; its radius is about 25 kilometres (16 mi) smaller at the poles than at the equator.[6]
As a result, parts of the Arctic Ocean seabed are at least 13 kilometres (8.1 mi) closer to the Earth’s centre than the Challenger Deep seafloor.
In 2009, the Marianas Trench was established as a United States National Monument.[7]
Xenophyophores have been found in the trench by Scripps Institution of Oceanography researchers at a record depth of 10.6 kilometres (6.6 mi) below the sea surface.[8]
On 17 March 2013, researchers from the Scottish Association for Marine Science reported data that suggested microbial life forms thrive within the trench.[9][10]
“Because of its extreme depth, the Mariana Trench is cloaked in perpetual darkness and the temperature is just a few degrees above freezing.
The water pressure at the bottom of the trench is a crushing eight tons per square inch—or about a thousand times the standard atmospheric pressure at sea level. Pressure increases with depth.
The first and only time humans descended into the Challenger Deep was more than 50 years ago. In 1960, Jacques Piccard and Navy Lt. Don Walsh reached this goal in a U.S. Navy submersible, a bathyscaphe called the Trieste.
After a five-hour descent, the pair spent only a scant 20 minutes at the bottom and were unable to take any photographs due to clouds of silt stirred up by their passage.
Until Piccard and Walsh’s historic dive, scientists had debated whether life could exist under such extreme pressure. But at the bottom, the Trieste‘s floodlight illuminated a creature that Piccard thought was a flatfish, a moment that Piccard would later describe with excitement in a book about his journey. ...”

Since when is a trench considered to ba a “monument”?

Pretty sure I dated her once.
It’d be a perfect location for the SC state Fair.

Lifetime pass to the (future) Obama Presidential Library for the first one who can guess the film this still shot is from!
Don’t go down there, I’m warnin’ ya.
