What did James Cameron discover?

How deep is the Mariana Trench?
7 miles
It is 11,034 meters (36,201 feet) deep, which is almost 7 miles. Tell students that if you placed Mount Everest at the bottom of the Mariana Trench, the peak would still be 2,133 meters (7,000 feet) below sea level.
What NASA found in the ocean?
Here, Kepler’s supernova remnant was captured in a NASA image. Traces of rare forms of iron and plutonium have been found at the bottom of the Pacific Ocean, after some kind of cataclysm in outer space created this radioactive stuff and sent it raining down on our planet.
Are there undiscovered sea creatures?
Anywhere from one-third to two-thirds of sea life has not been discovered yet, by their estimate. Most of those hidden sea creatures are probably crustaceans, mollusks, worms and sea sponges, they said. The new database, called the World Register of Marine Species (WoRMS), fulfills deep human curiosity, Appeltans said.
How empty is the ocean?
The ocean is an interesting place.
As of the turn of the century (nearly 20 years ago now, but not much has changed), the National Oceanic and Atmospheric Administration (NOAA) estimated that as much as 95 percent of the ocean and 99 percent of the ocean floor remain unexplored.
How much sea life is undiscovered?
Researchers around the world continue to study marine life and habitats to help develop new strategies to preserve vital ocean ecosystems. Scientists estimate that 91 percent of ocean species have yet to be classified, and that more than eighty percent of our ocean is unmapped, unobserved, and unexplored..
What’s the newest animal discovered?
A new chameleon species, named the Wolfgang Böhme’s Ethiopian chameleon, was found living in bushes and small trees in the Bale Mountains of south-central Ethiopia. The chameleon is around 15 centimeters (6 inches) long and has a distinctive crest of large spiny scales along its back and tail.
How many ocean creatures have been discovered?

What is the deepest ocean?

What is the deepest man has gone in the ocean?
Vescovo’s trip to the Challenger Deep, at the southern end of the Pacific Ocean’s Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).
Are there monsters in the Mariana Trench?
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
How deep can humans go in the ocean?
How deep in the ocean can the human body go? That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.

How much pee is in the ocean?
The volume of the Atlantic Ocean is about 350 quintillion liters. That’s 350 and 18 zeroes. If every person on earth had the average amount of pee containing the average amount of urea into the Atlantic, there’d be just 60 parts per trillion of urea in the ocean.
Why do we only know 5 of the ocean?
In fact, it’s easier to send a person to space than it is to send one down to the bottom of the deepest part of the ocean. In short, we’ve only explored 5 percent of the oceans, because exploring the depths is so treacherous and difficult.
