Go to Earth's Deepest Spot —for $750K

More people have been to space than to Challenger Deep

(Newser) - If now sounds like a good time to escape to the bottom of the Mariana Trench, with $750,000 you probably can. For that price, explorer and retired naval officer Victor Vescovo will take daring travelers to the deepest point on Earth, Challenger Deep in Mariana Trench, which has been...

Deep-Sea Explorer Went as Low as You Can Go in 5 Oceans

Vescovo is now considering a space mission

(Newser) - The Molloy Deep, 3.4 miles below the surface of the Arctic Ocean, has two things in common with the South Sandwich Trench in the Southern Ocean: It's the deepest spot in that ocean, and Victor Vescovo is the only person who has ever been there. Vescovo, a 53-year-old...

Plastic Bag Found in Truly Depressing Spot

Not even the bottom of the Mariana Trench is safe from our trash

(Newser) - "Single-use plastic reached the world's deepest ocean trench at 10,898 m," states the study plainly, referring to that great scourge: the plastic bag. National Geographic reports that a review of the Deep-Sea Debris Database, an assemblage of photos and videos taken during roughly 5,000 dives...

Evidence of Deepest Life on Earth Found Near Mariana Trench

Microbes could be living up to 6 miles under the seafloor

(Newser) - A team of researchers may have discovered evidence of the deepest life on Earth (and we're not talking college freshmen taking their first philosophy class). According to a study published Monday in Proceedings of the National Academy of Sciences , there may be microbes living up to six miles under...

In Deepest Part of Ocean, 'Sky High' Pollution

Toxic chemicals reach 6 miles deep in ocean: study

(Newser) - At the deepest spot in the ocean, scientists have found beer cans, plastic bags, a tin of Spam, and now tiny crustaceans contaminated with toxic chemicals banned nearly 50 years ago. The "extraordinary levels" of pollution in the Mariana Trench in the western Pacific Ocean and the Kermadec Trench...

Near Ocean's Deepest Spot, a 3.5-Second Symphony

Scientists believe it comes from minke whales

(Newser) - The 3.5-second symphony covers nearly half of the sound range that humans can hear, rising from a frequency as low as 38 hertz to an 8,000-hertz "metallic finale." But unless you make a detour to waters above the deepest spot in the ocean, you might never...

Humans Have Polluted Deepest Part of the Oceans: Study

Crustaceans in Mariana, Kermadec trenches rife with chemicals

(Newser) - Survival of the fittest in the depths of the sea likely includes plenty of its own inherent challenges, but now it's got a man-made one to add to the list. A research team out of Scotland's University of Aberdeen has discovered high concentrations of human-created organic pollutants in...

At Ocean's Deepest Point, You Might Expect Silence. Not So

Researchers surprised by 'almost constant noise'

Earth's Deepest Spot Is Alive With 'Unexpected' Bacteria

Microscopic bacteria are alive and well in the Mariana Trench's deepest canyon

(Newser) - To the naked eye, life gets scarce the deeper into the ocean one goes. But both the ocean's surfaces and its floors are teeming with microscopic life, and the deepest point of all—the Challenger Deep canyon in the Mariana Trench nearly seven miles below sea level—is home...

Deep-Sea Sub Vanishes 6 Miles Down

Scientists believe the Nereus imploded due to the pressure

(Newser) - Some 6.2 miles below the surface of the Pacific, tragedy very likely struck. What the BBC describes as one of the "most capable deep-sea research subs" in existence has vanished—and likely imploded. The $8 million Nereus was in the Kermadec Trench northeast of New Zealand, among the...

James Cameron Donates Historic Sub to Researchers

Still, 'I'd like to go dive the sub again'

Things Can Actually Live at the Ocean's Deepest Point

Bacteria makes a home 8 miles underwater

(Newser) - The Pacific Ocean's Mariana Trench contains the deepest point in all the world's oceans. But despite its nearly eight-mile depth (Mount Everest, by comparison, doesn't hit six miles), Challenger Deep is also home to life, a study finds. Researchers sent a robot into Challenger Deep in 2010...
